Climate Change Essay for Students and Children

500+ words climate change essay.

Climate change refers to the change in the environmental conditions of the earth. This happens due to many internal and external factors. The climatic change has become a global concern over the last few decades. Besides, these climatic changes affect life on the earth in various ways. These climatic changes are having various impacts on the ecosystem and ecology. Due to these changes, a number of species of plants and animals have gone extinct.

When Did it Start?

The climate started changing a long time ago due to human activities but we came to know about it in the last century. During the last century, we started noticing the climatic change and its effect on human life. We started researching on climate change and came to know that the earth temperature is rising due to a phenomenon called the greenhouse effect. The warming up of earth surface causes many ozone depletion, affect our agriculture , water supply, transportation, and several other problems.

Reason Of Climate Change

Although there are hundreds of reason for the climatic change we are only going to discuss the natural and manmade (human) reasons.

Get the huge list of more than 500 Essay Topics and Ideas

Natural Reasons

These include volcanic eruption , solar radiation, tectonic plate movement, orbital variations. Due to these activities, the geographical condition of an area become quite harmful for life to survive. Also, these activities raise the temperature of the earth to a great extent causing an imbalance in nature.

Human Reasons

Man due to his need and greed has done many activities that not only harm the environment but himself too. Many plant and animal species go extinct due to human activity. Human activities that harm the climate include deforestation, using fossil fuel , industrial waste , a different type of pollution and many more. All these things damage the climate and ecosystem very badly. And many species of animals and birds got extinct or on a verge of extinction due to hunting.

Effects Of Climatic Change

These climatic changes have a negative impact on the environment. The ocean level is rising, glaciers are melting, CO2 in the air is increasing, forest and wildlife are declining, and water life is also getting disturbed due to climatic changes. Apart from that, it is calculated that if this change keeps on going then many species of plants and animals will get extinct. And there will be a heavy loss to the environment.

What will be Future?

If we do not do anything and things continue to go on like right now then a day in future will come when humans will become extinct from the surface of the earth. But instead of neglecting these problems we start acting on then we can save the earth and our future.

Although humans mistake has caused great damage to the climate and ecosystem. But, it is not late to start again and try to undo what we have done until now to damage the environment. And if every human start contributing to the environment then we can be sure of our existence in the future.

Our Future Is Now - A Climate Change Essay by Francesca Minicozzi, '21

Francesca Minicozzi (class of 2021) is a Writing/Biology major who plans to study medicine after graduation. She wrote this essay on climate change for WR 355/Travel Writing, which she took while studying abroad in Newcastle in spring 2020. Although the coronavirus pandemic curtailed Francesca’s time abroad, her months in Newcastle prompted her to learn more about climate change. Terre Ryan Associate Professor, Writing Department

Our Future Is Now

By Francesca Minicozzi, '21 Writing and Biology Major

“If you don’t mind me asking, how is the United States preparing for climate change?” my flat mate, Zac, asked me back in March, when we were both still in Newcastle. He and I were accustomed to asking each other about the differences between our home countries; he came from Cambridge, while I originated in Long Island, New York. This was one of our numerous conversations about issues that impact our generation, which we usually discussed while cooking dinner in our communal kitchen. In the moment of our conversation, I did not have as strong an answer for him as I would have liked. Instead, I informed him of the few changes I had witnessed within my home state of New York.

Zac’s response was consistent with his normal, diplomatic self. “I have been following the BBC news in terms of the climate crisis for the past few years. The U.K. has been working hard to transition to renewable energy sources. Similar to the United States, here in the United Kingdom we have converted over to solar panels too. My home does not have solar panels, but a lot of our neighbors have switched to solar energy in the past few years.”

“Our two countries are similar, yet so different,” I thought. Our conversation continued as we prepared our meals, with topics ranging from climate change to the upcoming presidential election to Britain’s exit from the European Union. However, I could not shake the fact that I knew so little about a topic so crucial to my generation.

After I abruptly returned home from the United Kingdom because of the global pandemic, my conversation with my flat mate lingered in my mind. Before the coronavirus surpassed climate change headlines, I had seen the number of internet postings regarding protests to protect the planet dramatically increase. Yet the idea of our planet becoming barren and unlivable in a not-so-distant future had previously upset me to the point where a part of me refused to deal with it. After I returned from studying abroad, I decided to educate myself on the climate crisis.

My quest for climate change knowledge required a thorough understanding of the difference between “climate change” and “global warming.” Climate change is defined as “a pattern of change affecting global or regional climate,” based on “average temperature and rainfall measurements” as well as the frequency of extreme weather events. 1 These varied temperature and weather events link back to both natural incidents and human activity. 2 Likewise, the term global warming was coined “to describe climate change caused by humans.” 3 Not only that, but global warming is most recently attributed to an increase in “global average temperature,” mainly due to greenhouse gas emissions produced by humans. 4

I next questioned why the term “climate change” seemed to take over the term “global warming” in the United States. According to Frank Luntz, a leading Republican consultant, the term “global warming” functions as a rather intimidating phrase. During George W. Bush’s first presidential term, Luntz argued in favor of using the less daunting phrase “climate change” in an attempt to overcome the environmental battle amongst Democrats and Republicans. 5 Since President Bush’s term, Luntz remains just one political consultant out of many politicians who has recognized the need to address climate change. In an article from 2019, Luntz proclaimed that political parties aside, the climate crisis affects everyone. Luntz argued that politicians should steer clear of trying to communicate “the complicated science of climate change,” and instead engage voters by explaining how climate change personally impacts citizens with natural disasters such as hurricanes, tornadoes, and forest fires. 6 He even suggested that a shift away from words like “sustainability” would gear Americans towards what they really want: a “cleaner, safer, healthier” environment. 7

The idea of a cleaner and heathier environment remains easier said than done. The Paris Climate Agreement, introduced in 2015, began the United Nations’ “effort to combat global climate change.” 8 This agreement marked a global initiative to “limit global temperature increase in this century to 2 degrees Celsius above preindustrial levels,” while simultaneously “pursuing means to limit the increase to 1.5 degrees.” 9 Every country on earth has joined together in this agreement for the common purpose of saving our planet. 10 So, what could go wrong here? As much as this sounds like a compelling step in the right direction for climate change, President Donald Trump thought otherwise. In June 2017, President Trump announced the withdrawal of the United States from the Paris Agreement with his proclamation of climate change as a “’hoax’ perpetrated by China.” 11 President Trump continued to question the scientific facts behind climate change, remaining an advocate for the expansion of domestic fossil fuel production. 12 He reversed environmental policies implemented by former President Barack Obama to reduce fossil fuel use. 13

Trump’s actions against the Paris Agreement, however, fail to represent the beliefs of Americans as a whole. The majority of American citizens feel passionate about the fight against climate change. To demonstrate their support, some have gone as far as creating initiatives including America’s Pledge and We Are Still In. 14 Although the United States officially exited the Paris Agreement on November 4, 2020, this withdrawal may not survive permanently. 15 According to experts, our new president “could rejoin in as short as a month’s time.” 16 This offers a glimmer of hope.

The Paris Agreement declares that the United States will reduce greenhouse gas emission levels by 26 to 28 percent by the year 2025. 17 As a leader in greenhouse gas emissions, the United States needs to accept the climate crisis for the serious challenge that it presents and work together with other nations. The concept of working coherently with all nations remains rather tricky; however, I remain optimistic. I think we can learn from how other countries have adapted to the increased heating of our planet. During my recent study abroad experience in the United Kingdom, I was struck by Great Britain’s commitment to combating climate change.

Since the United Kingdom joined the Paris Agreement, the country targets a “net-zero” greenhouse gas emission for 2050. 18 This substantial alteration would mark an 80% reduction of greenhouse gases from 1990, if “clear, stable, and well-designed policies are implemented without interruption.” 19 In order to stay on top of reducing emissions, the United Kingdom tracks electricity and car emissions, “size of onshore and offshore wind farms,” amount of homes and “walls insulated, and boilers upgraded,” as well as the development of government policies, including grants for electric vehicles. 20 A strong grip on this data allows the United Kingdom to target necessary modifications that keep the country on track for 2050. In my brief semester in Newcastle, I took note of these significant changes. The city of Newcastle is small enough that many students and faculty are able to walk or bike to campus and nearby essential shops. However, when driving is unavoidable, the majority of the vehicles used are electric, and many British citizens place a strong emphasis on carpooling to further reduce emissions. The United Kingdom’s determination to severely reduce greenhouse emissions is ambitious and particularly admirable, especially as the United States struggles to shy away from its dependence on fossil fuels.

So how can we, as Americans, stand together to combat global climate change? Here are five adjustments Americans can make to their homes and daily routines that can dramatically make a difference:

Stay cautious of food waste. Studies demonstrate that “Americans throw away up to 40 percent of the food they buy.” 21 By being more mindful of the foods we purchase, opting for leftovers, composting wastes, and donating surplus food to those in need, we can make an individual difference that impacts the greater good. 22
Insulate your home. Insulation functions as a “cost-effective and accessible” method to combat climate change. 23 Homes with modern insulation reduce energy required to heat them, leading to a reduction of emissions and an overall savings; in comparison, older homes can “lose up to 35 percent of heat through their walls.” 24
Switch to LED Lighting. LED stands for “light-emitting diodes,” which use “90 percent less energy than incandescent bulbs and half as much as compact fluorescents.” 25 LED lights create light without producing heat, and therefore do not waste energy. Additionally, these lights have a longer duration than other bulbs, which means they offer a continuing savings. 26
Choose transportation wisely. Choose to walk or bike whenever the option presents itself. If walking or biking is not an option, use an electric or hybrid vehicle which emits less harmful gases. Furthermore, reduce the number of car trips taken, and carpool with others when applicable.
Finally, make your voice heard. The future of our planet remains in our hands, so we might as well use our voices to our advantage. Social media serves as a great platform for this. Moreover, using social media to share helpful hints to combat climate change within your community or to promote an upcoming protest proves beneficial in the long run. If we collectively put our voices to good use, together we can advocate for change.

As many of us are stuck at home due to the COVID-19 pandemic, these suggestions are slightly easier to put into place. With numerous “stay-at-home” orders in effect, Americans have the opportunity to make significant achievements for climate change. Personally, I have taken more precautions towards the amount of food consumed within my household during this pandemic. I have been more aware of food waste, opting for leftovers when too much food remains. Additionally, I have realized how powerful my voice is as a young college student. Now is the opportunity for Americans to share how they feel about climate change. During this unprecedented time, our voice is needed now more than ever in order to make a difference.

However, on a much larger scale, the coronavirus outbreak has shed light on reducing global energy consumption. Reductions in travel, both on the roads and in the air, have triggered a drop in emission rates. In fact, the International Energy Agency predicts a 6 percent decrease in energy consumption around the globe for this year alone. 27 This drop is “equivalent to losing the entire energy demand of India.” 28 Complete lockdowns have lowered the global demand for electricity and slashed CO2 emissions. However, in New York City, the shutdown has only decreased carbon dioxide emissions by 10 percent. 29 This proves that a shift in personal behavior is simply not enough to “fix the carbon emission problem.” 30 Climate policies aimed to reduce fossil fuel production and promote clean technology will be crucial steppingstones to ameliorating climate change effects. Our current reduction of greenhouse gas emissions serves as “the sort of reduction we need every year until net-zero emissions are reached around 2050.” 31 From the start of the coronavirus pandemic, politicians came together for the common good of protecting humanity; this demonstrates that when necessary, global leaders are capable of putting humankind above the economy. 32

After researching statistics comparing the coronavirus to climate change, I thought back to the moment the virus reached pandemic status. I knew that a greater reason underlay all of this global turmoil. Our globe is in dire need of help, and the coronavirus reminds the world of what it means to work together. This pandemic marks a turning point in global efforts to slow down climate change. The methods we enact towards not only stopping the spread of the virus, but slowing down climate change, will ultimately depict how humanity will arise once this pandemic is suppressed. The future of our home planet lies in how we treat it right now.

Climate Change Essay

500+ words essay on climate change.

Climate change is a major global challenge today, and the world is becoming more vulnerable to this change. Climate change refers to the changes in Earth’s climate condition. It describes the changes in the atmosphere which have taken place over a period ranging from decades to millions of years. A recent report from the United Nations predicted that the average global temperature could increase by 6˚ Celsius at the end of the century. Climate change has an adverse effect on the environment and ecosystem. With the help of this essay, students will get to know the causes and effects of climate change and possible solutions. Also, they will be able to write essays on similar topics and can boost their writing skills.

What Causes Climate Change?

The Earth’s climate has always changed and evolved. Some of these changes have been due to natural causes such as volcanic eruptions, floods, forest fires etc., but quite a few of them are due to human activities. Human activities such as deforestation, burning fossil fuels, farming livestock etc., generate an enormous amount of greenhouse gases. This results in the greenhouse effect and global warming which are the major causes of climate change.

Effects of Climate Change

If the current situation of climate change continues in a similar manner, then it will impact all forms of life on the earth. The earth’s temperature will rise, the monsoon patterns will change, sea levels will rise, and storms, volcanic eruptions and natural disasters will occur frequently. The biological and ecological balance of the earth will get disturbed. The environment will get polluted and humans will not be able to get fresh air to breathe and fresh water to drink. Life on earth will come to an end.

Steps to be Taken to Reduce Climate Change

The Government of India has taken many measures to improve the dire situation of Climate Change. The Ministry of Environment and Forests is the nodal agency for climate change issues in India. It has initiated several climate-friendly measures, particularly in the area of renewable energy. India took several steps and policy initiatives to create awareness about climate change and help capacity building for adaptation measures. It has initiated a “Green India” programme under which various trees are planted to make the forest land more green and fertile.

We need to follow the path of sustainable development to effectively address the concerns of climate change. We need to minimise the use of fossil fuels, which is the major cause of global warming. We must adopt alternative sources of energy, such as hydropower, solar and wind energy to make a progressive transition to clean energy. Mahatma Gandhi said that “Earth provides enough to satisfy every man’s need, but not any man’s greed”. With this view, we must remodel our outlook and achieve the goal of sustainable development. By adopting clean technologies, equitable distribution of resources and addressing the issues of equity and justice, we can make our developmental process more harmonious with nature.

We — Ayana Elizabeth Johnson and Katharine Wilkinson — are climate experts who focus on solutions, leadership and building community.

We are a natural and a social scientist, a Northerner and a Southerner. We’re also both lifelong interdisciplinarians in love with words and the cofounders of The All We Can Save Project , in support of women climate leaders.

Our collaboration has led us to read widely and deeply about the climate crisis that’s facing humanity. Here are 15 of our favorite writings on climate — this eclectic list contains books, essays, a newsletter, a scientific paper, even legislation and they’re all ones we wholeheartedly recommend.

All We Can Save: Truth, Courage, and Solutions for the Climate Crisis coedited by Ayana Elizabeth Johnson and Katharine Wilkinson

We had the honor of editing this collection of 41 essays, 17 poems, quotes and original illustrations — so naturally we love it! But you don’t have to take our word for it. As Rolling Stone said : “Taken together, the breadth of their voices forms a mosaic that honors the complexity of the climate crisis like few, if any, books on the topic have done yet. … The book is a feast of ideas and perspectives, setting a big table for the climate movement, declaring all are welcome.” All We Can Save nourished, educated and transformed us as we shaped its pages, and we can’t wait for it to do the same for you.

Ghost Fishing: An Eco-justice Poetry Anthology edited by Melissa Tuckey

We count ourselves among those who can’t make sense of the climate crisis without the aid of poets, who help us to see more clearly, feel our feelings, catch our breath, and know we’re not alone. This anthology is a magnificent quilt of poems that are made for this moment and all its intersections.

“We Don’t Have to Halt Climate Action to Fight Racism” by Mary Annaïse Heglar

“Climate People,” as she likes to call us, should be grateful that Mary Annaïse Heglar decided a few years back to pick up her pen once more as a writer. All of her essays are necessary reading, but this one is especially so, crafted from Mary’s perspective as a “Black Climate Person.” It’s a powerful articulation of the inextricability of a society that values Black lives and a livable planet for all.

Sacred Instructions: Indigenous Wisdom for Living Spirit-Based Change by Sherri Mitchell — Weh’na Ha’mu Kwasset

Weh’na Ha’mu Kwasset means “she who brings the light,” and Sherri Mitchell does exactly that in this incredible tapestry of a book, which begins with Penawahpskek Nation creation stories and concludes with guidance on what it means to live in a time of prophecy. It is rare that a book so generously shares wisdom, much less wisdom about how we got to where we are, what needs mending, and what a path forward that’s grounded in ancestral ways of knowing and being might look like.

Emergent Strategy: Shaping Change, Changing Worlds by adrienne maree brown

How lucky are we to be contemporaries of adrienne maree brown? Very. This is a book that we come back to time and time again to ground and enliven our work. We love this line from her about oak trees: “Under the earth, always, they reach for each other, they grow such that their roots are intertwined and create a system of strength that is as resilient on a sunny day as it is in a hurricane.” That’s the kind of community we’re trying to nurture.

“Circumstances Affecting the Heat of the Sun’s Rays” by Eunice Newton Foote

Eunice Newton Foote rarely gets the credit she’s due — and she deserves a lot of credit. In fact, we like to think of her as the first climate feminist. In 1856, she connected the dots between carbon dioxide and planetary warming, but science and history forgot (dismissed?) her until recently. This is her original paper, which was published in The American Journal of Science and Arts . Foote was also a signatory to the women’s rights manifesto created at Seneca Falls in 1848, alongside visionaries like Frederick Douglass.

The Drawdown Review by Project Drawdown

Full disclosure: Katharine is The Drawdown Review’ s editor-in-chief and principal writer. But Ayana fully endorses this recommendation — it’s a valuable resource as we charge ahead toward climate solutions. We all need to know what tools are in the toolbox, and The Drawdown Review is the latest compendium of climate solutions that already exist. This publication is beautifully designed, grounded in research, and you can access it for free.

The Green New Deal Resolution by the 116th US Congress

It seems that almost everyone has an opinion about the Green New Deal, but few people have read the actual piece of legislation: House Resolution 109: Recognizing the Duty of the Federal Government to Create a Green New Deal, which was introduced by Rep. Alexandria Ocasio-Cortez and Sen. Ed Markey. The big secret is that it’s only 14 pages! It makes a clear, compelling and concise case for what comprehensive climate policy should look like in the US. We’d love for everyone to read it so we can all have a more grounded discussion about what we might agree and disagree with and chart a course forward.

“Think This Pandemic Is Bad? We Have Another Crisis Coming” by Rhiana Gunn-Wright

Speaking of policy … this op-ed , penned by Rhiana Gunn-Wright, who is one of the policy leads for the Green New Deal, makes the connections between climate, justice, COVID-19 and our recession as clear as day. She lays out an ironclad case for the the need to address these issues together, and why. As she writes, “We need to design the stimulus not only to help the US economy recover but to also become more resilient to the climate crisis, the next multitrillion-dollar crisis headed our way.”

“How Can We Plan for a Future in California?” by Leah Stokes

In the midst of raging fires and continuing pandemic, UC Santa Barbara Professor Leah Stokes, who’s based in Santa Barbara, lays it plain in her piece : “I don’t want to live in a world where we have to decide which mask to wear for which disaster, but this is the world we are making. And we’ve only started to alter the climate. Imagine what it will be like when we’ve doubled or tripled the warming, as we are on track to do.” As she and others have been pointing out, journalists have been failing to make the critical connection: “What’s happening in California has a name: climate change.”

HEATED by Emily Atkin

This is the reading rec that keeps on giving, literally — it’s a daily newsletter that brings climate accountability journalism right to your inbox. It’s chock full of smarts, spunk, truth-telling and super timely writing that isn’t hemmed in by media overlords. If you’re pissed off about the climate crisis, Emily Atkin made HEATED just for you.

The July 20 2020 Issue of TIME Magazine

This entire issue, titled “One Last Chance”, is dedicated to coverage of climate, and it includes wise words from so many luminaries from politician Stacey Abrams to soil scientist Asmeret Asefaw Berhe , with a lead piece by Time ’s climate journalist Justin Worland. Ayana also has a piece in this issue called “ We Can’t Solve the Climate Crisis Unless Black Lives Matter .” To see all of this collected in one place — insights on topics from oceans to agriculture to politics to activism — was heartening. We hope there’s much more of this to come, from many magazines.

“Wakanda Doesn’t Have Suburbs” by Kendra Pierre Louis

A pop-culture connoisseur and expert storyteller, Kendra Pierre Louis takes up the topic of climate stories in her essay — the good, the bad, and the ugly. The good, she explains, are all too rare, and that’s a big problem because stories are powerful. Black Panther may be our best story of living thoughtfully and well on this planet, not least thanks to an absence of carbon-spewing suburbs. It’s going to take much better narratives, and many more of them, if humans are to, as she puts it, “repair our relationship with the Earth and re-envision our societies in ways that are not just in keeping with our ecosystems but also make our lives better.” !

“We Need Courage, Not Hope, to Face Climate Change” by Kate Marvel PhD

This piece by NASA climate scientist Kate Marvel is, as the kids say, a whole mood. Hope is not enough, hope is often passive, and that won’t get us where we need to go. Pretty much everyone who works on climate is constantly being asked what gives us hope — how presumptuous to assume we have it! But what we do have is courage. In spades. As Marvel writes in this poetic piece: “We need courage, not hope. Grief, after all, is the cost of being alive. We are all fated to live lives shot through with sadness, and are not worth less for it. Courage is the resolve to do well without the assurance of a happy ending.”

Truth, Courage, and Solutions for the Climate Crisis

Admittedly, this last recommendation isn’t something to read, but to watch and listen to. This playlist of TED Talks by women climate leaders (who were all contributors to our anthology All We Can Save — read about it above) will inspire you, deepen your understanding, connect the dots and help you find where you might fit into the heaps of climate work that needs doing. It includes poignant talks by Colette Pichon Battle and Christine Nieves Rodriguez , which are respectively about communities in Louisiana and Puerto Rico recovering from hurricanes and rebuilding resilience and which broke our hearts open. We were so moved we invited them to adapt their talks into essays for All We Can Save . Christine’s piece — “Community is Our Best Chance” — is the final essay in the book and the note we want to end on here. It’s not about what each of us can do as individuals to address the climate crisis; it’s about what we can do together . Building community around solutions is the most important thing.

Our climate change crisis

The climate change emergency.

Even in a world increasingly battered by weather extremes, the summer 2021 heat wave in the Pacific Northwest stood out. For several days in late June, cities such as Vancouver, Portland and Seattle baked in record temperatures that killed hundreds of people. On June 29 Lytton, a village in British Columbia, set an all-time heat record for Canada, at 121° Fahrenheit (49.6° Celsius); the next day, the village was incinerated by a wildfire.

Within a week, an international group of scientists had analyzed this extreme heat and concluded it would have been virtually impossible without climate change caused by humans. The planet’s average surface temperature has risen by at least 1.1 degree Celsius since preindustrial levels of 1850–1900 — because people are loading the atmosphere with heat-trapping gases produced during the burning of fossil fuels, such as coal and gas, and from cutting down forests.

A little over 1 degree of warming may not sound like a lot. But it has already been enough to fundamentally transform how energy flows around the planet. The pace of change is accelerating, and the consequences are everywhere. Ice sheets in Greenland and Antarctica are melting, raising sea levels and flooding low-lying island nations and coastal cities. Drought is parching farmlands and the rivers that feed them. Wildfires are raging. Rains are becoming more intense, and weather patterns are shifting .

The roots of understanding this climate emergency trace back more than a century and a half. But it wasn’t until the 1950s that scientists began the detailed measurements of atmospheric carbon dioxide that would prove how much carbon is pouring from human activities. Beginning in the 1960s, researchers began developing comprehensive computer models that now illuminate the severity of the changes ahead.

Global average temperature change, 1850–2021

Long-term climate datasets show that Earth’s average surface temperature (combined land and ocean) has increased by more than 1 degree Celsius since preindustrial times. Temperature change is the difference from the 1850–1900 average.

Today we know that climate change and its consequences are real, and we are responsible. The emissions that people have been putting into the air for centuries — the emissions that made long-distance travel, economic growth and our material lives possible — have put us squarely on a warming trajectory . Only drastic cuts in carbon emissions, backed by collective global will, can make a significant difference.

“What’s happening to the planet is not routine,” says Ralph Keeling, a geochemist at the Scripps Institution of Oceanography in La Jolla, Calif. “We’re in a planetary crisis.” — Alexandra Witze

Tracking a Greenland glacier

The calving front of Greenland’s Helheim Glacier, which flows toward the sea where it crumbles into icebergs, held roughly the same position from the 1970s until 2001 (left, the calving front is to the far right of the image). But by 2005 (right), it had retreated 7.5 kilometers toward its source.

The first climate scientists

One day in the 1850s, Eunice Newton Foote, an amateur scientist and women’s rights activist living in upstate New York, put two glass jars in sunlight. One contained regular air — a mix of nitrogen, oxygen and other gases including carbon dioxide — while the other contained just CO 2 . Both had thermometers in them. As the sun’s rays beat down, Foote observed that the jar of CO 2 alone heated more quickly, and was slower to cool, than the one containing plain air.

Illustration of Eunice Newton Foote. Hers were some of the first studies of climate change.

The results prompted Foote to muse on the relationship between CO 2 , the planet and heat. “An atmosphere of that gas would give to our earth a high temperature,” she wrote in an 1856 paper summarizing her findings .

Three years later, working independently and apparently unaware of Foote’s discovery, Irish physicist John Tyndall showed the same basic idea in more detail. With a set of pipes and devices to study the transmission of heat, he found that CO 2 gas, as well as water vapor, absorbed more heat than air alone. He argued that such gases would trap heat in Earth’s atmosphere, much as panes of glass trap heat in a greenhouse, and thus modulate climate. “As a dam built across a river causes a local deepening of the stream, so our atmosphere, thrown as a barrier across the terrestrial rays, produces a local heightening of the temperature at the Earth’s surface,” he wrote in 1862.

Today Tyndall is widely credited with the discovery of how what are now called greenhouse gases heat the planet, earning him a prominent place in the history of climate science. Foote faded into relative obscurity — partly because of her gender, partly because her measurements were less sensitive. Yet their findings helped kick off broader scientific exploration of how the composition of gases in Earth’s atmosphere affects global temperatures.

Carbon floods in

Humans began substantially affecting the atmosphere around the turn of the 19th century, when the Industrial Revolution took off in Britain. Factories burned tons of coal; fueled by fossil fuels, the steam engine revolutionized transportation and other industries. In the decades since, fossil fuels including oil and natural gas have been harnessed to drive a global economy. All these activities belch gases into the air.

Yet Svante Arrhenius, a Swedish physical chemist, wasn’t worried about the Industrial Revolution when he began thinking in the late 1800s about changes in atmospheric CO 2 levels. He was instead curious about ice ages — including whether a decrease in volcanic eruptions, which can put CO 2 into the atmosphere, would lead to a future ice age. Bored and lonely in the wake of a divorce, Arrhenius set himself to months of laborious calculations involving moisture and heat transport in the atmosphere at different zones of latitude. In 1896 he reported that halving the amount of CO 2 in the atmosphere could indeed bring about an ice age — and that doubling CO 2 would raise global temperatures by around 5 to 6 degrees C.

It was a remarkably prescient finding for work that, out of necessity, had simplified Earth’s complex climate system down to just a few variables. Today, estimates for how much the planet will warm through a doubling of CO 2 — a measure known as climate sensitivity — range between 1.5 degrees and 4.5 degrees Celsius. (The range remains broad in part because scientists now incorporate their understanding of many more planetary feedbacks than were recognized in Arrhenius’ day.)

But Arrhenius’ findings didn’t gain much traction with other scientists at the time. The climate system seemed too large, complex and inert to change in any meaningful way on a timescale that would be relevant to human society. Geologic evidence showed, for instance, that ice ages took thousands of years to start and end. What was there to worry about? And other laboratory experiments — later shown to be flawed — appeared to indicate that changing levels of CO 2 would have little impact on heat absorption in the atmosphere. Most scientists aware of the work came to believe that Arrhenius had been proved wrong.

One researcher, though, thought the idea was worth pursuing. Guy Stewart Callendar, a British engineer and amateur meteorologist, had tallied weather records over time, obsessively enough to determine that average temperatures were increasing at 147 weather stations around the globe. In 1938, in a paper in a Royal Meteorological Society journal , he linked this temperature rise to the burning of fossil fuels. Callendar estimated that fossil fuel burning had put around 150 billion metric tons of CO 2 into the atmosphere since the late 19th century.

Like many of his day, Callendar didn’t see global warming as a problem. Extra CO 2 would surely stimulate plants to grow and allow crops to be farmed in new regions. “In any case the return of the deadly glaciers should be delayed indefinitely,” he wrote. But his work revived discussions tracing back to Tyndall and Arrhenius about how the planetary system responds to changing levels of gases in the atmosphere. And it began steering the conversation toward how human activities might drive those changes.

When World War II broke out the following year, the global conflict redrew the landscape for scientific research. Hugely important wartime technologies, such as radar and the atomic bomb, set the stage for “big science” studies that brought nations together to tackle high-stakes questions of global reach. And that allowed modern climate science to emerge.

The Keeling curve and climate change

One major postwar effort was the International Geophysical Year, an 18-month push in 1957–1958 that involved a wide array of scientific field campaigns including exploration in the Arctic and Antarctica. Climate change wasn’t a high research priority during the IGY, but some scientists in California, led by Roger Revelle of the Scripps Institution of Oceanography in La Jolla, used the funding influx to begin a project they’d long wanted to do. The goal was to measure CO 2 levels at different locations around the world, accurately and consistently.

The job fell to geochemist Charles David Keeling, who put ultraprecise CO 2 monitors in Antarctica and on the Hawaiian volcano of Mauna Loa. Funds soon ran out to maintain the Antarctic record, but the Mauna Loa measurements continued. Thus was born one of the most iconic datasets in all of science — the “Keeling curve,” which tracks the rise of atmospheric CO 2 . When Keeling began his measurements in 1958, CO 2 made up 315 parts per million of the global atmosphere. Within just a few years it became clear that the number was increasing year by year. Because plants take up CO 2 as they grow in spring and summer and release it as they decompose in fall and winter, CO 2 concentrations rose and fell each year in a sawtooth pattern — but superimposed on that pattern was a steady march upward.

Monthly average CO 2 concentrations at Mauna Loa Observatory

Atmospheric carbon dioxide measurements collected continuously since 1958 at Mauna Loa volcano in Hawaii show the rise due to human activities. The visible sawtooth pattern is due to seasonal plant growth: Plants take up CO 2 in the growing seasons, then release it as they decompose in fall and winter.

“The graph got flashed all over the place — it was just such a striking image,” says Ralph Keeling, who is Charles David Keeling’s son. Over the years, as the curve marched higher, “it had a really important role historically in waking people up to the problem of climate change.” The Keeling curve has been featured in countless earth science textbooks, congressional hearings and in Al Gore’s 2006 documentary on climate change, An Inconvenient Truth . Each year the curve keeps going up: In 2016 it passed 400 ppm of CO 2 in the atmosphere, as measured during its typical annual minimum in September. In 2021, the annual minimum was 413 ppm. (Before the Industrial Revolution, CO 2 levels in the atmosphere had been stable for centuries at around 280 ppm.)

Around the time that Keeling’s measurements were kicking off, Revelle also helped develop an important argument that the CO 2 from human activities was building up in Earth’s atmosphere. In 1957 he and Hans Suess, also at Scripps at the time, published a paper that traced the flow of radioactive carbon through the oceans and the atmosphere. They showed that the oceans were not capable of taking up as much CO 2 as previously thought; the implication was that much of the gas must be going into the atmosphere instead. “Human beings are now carrying out a large-scale geophysical experiment of a kind that could not have happened in the past nor be reproduced in the future,” Revelle and Suess wrote in the paper. It’s one of the most famous sentences in earth science history.

“Human beings are now carrying out a large-scale geophysical experiment of a kind that could not have happened in the past nor be reproduced in the future.”

Here was the insight underlying modern climate science: Atmosheric CO 2 is increasing, and humans are causing the buildup. Revelle and Suess became the final piece in a puzzle dating back to Svante Arrhenius and John Tyndall.

“I tell my students that to understand the basics of climate change, you need to have the cutting-edge science of the 1860s, the cutting-edge math of the 1890s and the cutting-edge chemistry of the 1950s,” says Joshua Howe, an environmental historian at Reed College in Portland, Ore.

Environmental awareness grows

As this scientific picture began to emerge in the late 1950s, Science News was on the story. A March 1, 1958 article in Science News Letter , “Weather May Be Warming,” described a warm winter month in the Northern Hemisphere. It posits three theories, including that “carbon dioxide poured into the atmosphere by a booming industrial civilization could have caused the increase. By burning up about 100 billion tons of coal and oil since 1900, man himself may be changing the climate.” By 1972, the magazine was reporting on efforts to expand global atmospheric greenhouse gas monitoring beyond Keeling’s work; two years later, the U.S. National Oceanic and Atmospheric Administration launched its own CO 2 monitoring network, now the biggest in the world.

Environmental awareness on other issues grew in the 1960s and 1970s. Rachel Carson catalyzed the modern U.S. environmental movement in 1962 when she published a magazine series and then a book, Silent Spring , condemning the pesticide DDT for its ecological impacts. 1970 saw the celebration of the first Earth Day , in the United States and elsewhere, and in India in 1973 a group of women led a series of widely publicized protests against deforestation. This Chipko movement explicitly linked environmental protection with protecting human communities, and helped seed other environmental movements.

The fragility of global energy supplies was also becoming more obvious through the 1970s. The United States, heavily dependent on other countries for oil imports, entered a gas shortage in 1973–74 when Arab members of the Organization of the Petroleum Exporting Countries cut off oil supplies because of U.S. government support for Israel. The shortage prompted more people to think about the finiteness of natural resources and the possibility of overtaxing the planet. — Alexandra Witze

Climate change evidence piles up

Observational data collected throughout the second half of the 20th century helped researchers gradually build their understanding of how human activities were transforming the planet. “It was a sort of slow accretion of evidence and concern,” says historian Joshua Howe of Reed College.

Environmental records from the past, such as tree rings and ice cores, established that the current changes in climate are unusual compared with the recent past. Yet such paleoclimatology data also showed that climate has changed quickly in the deep past — driven by triggers other than human activity, but with lessons for how abrupt planetary transformations can be.

Ice cores pulled from ice sheets, such as that atop Greenland, offer some of the most telling insights for understanding past climate change. Each year snow falls atop the ice and compresses into a fresh layer of ice representing climate conditions at the time it formed. The abundance of certain forms, or isotopes, of oxygen and hydrogen in the ice allows scientists to calculate the temperature at which it formed, and air bubbles trapped within the ice reveal how much carbon dioxide and other greenhouse gases were in the atmosphere at that time. So drilling down into an ice sheet is like reading the pages of a history book that go back in time the deeper you go.

Scientists began reading these pages in the early 1960s, using ice cores drilled at a U.S. military base in northwest Greenland . Contrary to expectations that past climates were stable, the cores hinted that abrupt climate shifts had happened over the last 100,000 years. By 1979, an international group of researchers was pulling another deep ice core from a second location in Greenland — and it, too, showed that abrupt climate change had occurred in the past. In the late 1980s and early 1990s a pair of European- and U.S.-led drilling projects retrieved even deeper cores from near the top of the ice sheet, pushing the record of past temperatures back a quarter of a million years.

Together with other sources of information, such as sediment cores drilled from the seafloor and molecules preserved in ancient rocks, the ice cores allowed scientists to reconstruct past temperature changes in extraordinary detail. Many of those changes happened alarmingly fast. For instance, the climate in Greenland warmed abruptly more than 20 times in the last 80,000 years, with the changes occurring in a matter of decades. More recently, a cold spell that set in around 13,000 years ago suddenly came to an end around 11,500 years ago — and temperatures in Greenland rose 10 degrees Celsius in a decade.

Evidence for such dramatic climate shifts laid to rest any lingering ideas that global climate change would be slow and unlikely to occur on a timescale that humans should worry about. “It’s an important reminder of how ‘tippy’ things can be,” says Jessica Tierney, a paleoclimatologist at the University of Arizona in Tucson.

More evidence of global change came from Earth-observing satellites, which brought a new planet-wide perspective on global warming beginning in the 1960s. From their viewpoint in the sky, satellites have measured the steady rise in global sea level — currently 3.4 millimeters per year and accelerating, as warming water expands and as ice sheets melt — as well as the rapid decline in ice left floating on the Arctic Ocean each summer at the end of the melt season. Gravity-sensing satellites have ‘weighed’ the Antarctic and Greenlandic ice sheets from above since 2002, reporting that more than 400 billion metric tons of ice are lost each year.

Temperature observations taken at weather stations around the world also confirm that we are living in the hottest years on record. The 10 warmest years since record keeping began in 1880 have all occurred since 2005. And nine of those 10 have come since 2010.

What’s more, extreme weather is hammering the planet more and more frequently. That 2021 heat wave in the Pacific Northwest, for instance, is just a harbinger of what’s to come. — Alexandra Witze

Worrisome predictions from climate models

By the 1960s, there was no denying that the planet was warming. But understanding the consequences of those changes — including the threat to human health and well-being — would require more than observational data. Looking to the future depended on computer simulations: complex calculations of how energy flows through the planetary system. Such models of the climate system have been crucial to developing projections for what we can expect from greenhouse warming.

A first step in building climate models was to connect everyday observations of weather to the concept of forecasting future climate. During World War I, the British mathematician Lewis Fry Richardson imagined tens of thousands of meteorologists working to forecast the weather, each calculating conditions for a small part of the atmosphere but collectively piecing together a global forecast. Richardson published his work in 1922, to reviews that called the idea “of almost quixotic boldness.”

Charney paper (first weather predictions with ENIAC)

But it wasn’t until after World War II that computational power turned Richardson’s dream into reality. In the wake of the Allied victory, which relied on accurate weather forecasts for everything from planning D-Day to figuring out when and where to drop the atomic bombs, leading U.S. mathematicians acquired funding from the federal government to improve predictions. In 1950 a team led by Jule Charney, a meteorologist at the Institute for Advanced Study in Princeton, N.J., used the ENIAC, the first general-purpose, programmable electronic computer, to produce the first computer-driven regional weather forecast . The forecasting was slow and rudimentary, but it built on Richardson’s ideas of dividing the atmosphere into squares, or cells, and computing the weather for each of those. With the obscure title “Numerical integration of the barotropic vorticity equation,” the paper reporting the results set the stage for decades of climate modeling to follow.

By 1956 Norman Phillips, a member of Charney’s team, had produced the world’s first general circulation model, which captured how energy flows between the oceans, atmosphere and land. Phillips ran the calculations on a computer with just 5 kilobytes of memory, yet it was able to reproduce monthly and seasonal patterns in the lower atmosphere. That meant scientists could begin developing more realistic models of how the planet responds to factors such as increasing levels of greenhouse gases. The field of climate modeling was born.

The work was basic at first, because early computers simply didn’t have much computational power to simulate all aspects of the planetary system. “People thought that it was stupid to try to study this greenhouse-warming issue by three-dimensional model[s], because it cost so much computer time,” meteorologist Syukuro Manabe told physics historian Spencer Weart in a 1989 oral history .

Climate models have predicted how much ice the Ilulissat region of the Greenland ice sheet might lose by 2300 based on different scenarios for greenhouse gas emissions. The models are compared to 2008 (first image). In a best-case scenario, in which emissions peak by mid-century, the speed at which the glacier is sending ice out into the ocean is much lower (second image) than with a worst-case scenario, in which emissions rise at a high rate (third image).

An important breakthrough came in 1967, when Manabe and Richard Wetherald — both at the Geophysical Fluid Dynamics Laboratory in Princeton, a lab born from Charney’s group — published a paper in the Journal of the Atmospheric Sciences that modeled connections between Earth’s surface and atmosphere and calculated how changes in carbon dioxide would affect the planet’s temperature. Manabe and Wetherald were the first to build a computer model that captured the relevant processes that drive climate , and to accurately simulate how the Earth responds to those processes. (Manabe shared the 2021 Nobel Prize in physics for his work on climate modeling; Wetherald died in 2011.)

The rise of climate modeling allowed scientists to more accurately envision the impacts of global warming. In 1979, Charney and other experts met in Woods Hole, Mass., to try to put together a scientific consensus on what increasing levels of CO 2 would mean for the planet. They analyzed climate models from Manabe and from James Hansen of NASA. The resulting “Charney report” concluded that rising CO 2 in the atmosphere would lead to additional and significant climate change. The ocean might take up much of that heat, the scientists wrote — but “it appears that the warming will eventually occur, and the associated regional climatic changes so important to the assessment of socioeconomic consequence may well be significant.”

In the decades since, climate modeling has gotten increasingly sophisticated . Scientists have drawn up a variety of scenarios for how carbon emissions might change in the future, depending on the stringency of emissions cuts. Modelers use those scenarios to project how climate and weather will change around the globe, from hotter croplands in China to melting glaciers in the Himalayas. Climate simulations have also allowed researchers to identify the fingerprints of human impacts on extreme weather that is already happening, by comparing scenarios that include the influence of human activities with those that do not.

And as climate science firmed up and the most dramatic consequences became clear, the political battles raged. — Alexandra Witze

Climate science meets politics

With the development of climate science tracing back to the early Cold War, perhaps it shouldn’t be a surprise that the science of global warming became enmeshed in broader societal and political battles. A complex stew of political, national and business interests mired society in debates about the reality of climate change, and what to do about it, decades after the science became clear that humans are fundamentally altering the planet’s atmosphere.

Society has pulled itself together before to deal with global environmental problems, such as the Antarctic ozone hole. In 1974 chemists Mario Molina and F. Sherwood Rowland, both of the University of California, Irvine, reported that chlorofluorocarbon chemicals, used in products such as spray cans and refrigerants, caused a chain of reactions that gnawed away at the atmosphere’s protective ozone layer . The resulting ozone hole, which forms over Antarctica every spring, allows more ultraviolet radiation from the sun to make it through Earth’s atmosphere and reach the surface, where it can cause skin cancer and eye damage.

Governments ultimately worked under the auspices of the United Nations to craft the 1987 Montreal Protocol, which strictly limited the manufacture of chlorofluorocarbons . In the years following, the ozone hole began to heal. But fighting climate change would prove to be far more challenging. Chlorofluorocarbons were a suite of chemicals with relatively limited use and for which replacements could be found without too much trouble. But the greenhouse gases that cause global warming stem from a wide variety of human activities, from energy development to deforestation. And transforming entire energy sectors to reduce or eliminate carbon emissions is much more difficult than replacing a set of industrial chemicals.

In 1980, though, researchers took an important step toward banding together to synthesize the scientific understanding of climate change and bring it to the attention of international policy makers. It started at a small scientific conference in Villach, Austria. There, experts met under the auspices of the World Meteorological Organization, the International Council of Scientific Unions and the United Nations Environment Program to discuss the seriousness of climate change. On the train ride home from the meeting, Swedish meteorologist Bert Bolin talked with other participants about how a broader, deeper and more international analysis was needed. In 1985, a second conference was held at Villach to highlight the urgency, and in 1988, the Intergovernmental Panel on Climate Change, the IPCC, was born. Bolin was its first chairperson.

The IPCC became a highly influential and unique body. It performs no original scientific research; instead, it synthesizes and summarizes the vast literature of climate science for policy makers to consider — primarily through massive reports issued every couple of years. The first IPCC report , in 1990, predicted that the planet’s global mean temperature would rise more quickly in the following century than at any point in the last 10,000 years, due to increasing greenhouse gases in the atmosphere. Successive IPCC reports showed more and more confidence in the link between greenhouse emissions and rising global temperatures — and explored how society might mitigate and adapt to coming changes.

IPCC reports have played a key role in providing scientific information for nations discussing how to stabilize greenhouse gas concentrations. This process started with the Rio Earth Summit in 1992 , which resulted in the U.N. Framework Convention on Climate Change. Annual U.N. meetings to tackle climate change led to the first international commitments to reduce emissions, the Kyoto Protocol of 1997. Under it, developed countries committed to reduce emissions of CO 2 and other greenhouse gases. By 2007 the IPCC declared that the reality of climate warming is “unequivocal ”; the group received the Nobel Peace Prize that year along with Al Gore for their work on climate change.

The IPCC process ensured that policy makers had the best science at hand when they came to the table to discuss cutting emissions. “If you go back and look at the original U.N. framework on climate change, already you see the core of the science represented there,” says Rachel Cleetus, a climate policy expert with the Union of Concerned Scientists in Cambridge, Mass. Of course, nations did not have to abide by that science — and they often didn’t.

Throughout the 2000s and 2010s, international climate meetings discussed less hard-core science and more issues of equity. Countries such as China and India pointed out that they needed energy to develop their economies, and that nations responsible for the bulk of emissions through history, such as the United States, needed to lead the way in cutting greenhouse gases. Meanwhile, residents of some of the most vulnerable nations, such as low-lying islands that are threatened by sea level rise, gained visibility and clout at international negotiating forums. “The issues around equity have always been very uniquely challenging in this collective action problem,” says Cleetus.

By 2015, the world’s nations had made some progress on the emissions cuts laid out in the Kyoto Protocol, but it was still not enough to achieve substantial global reductions. That year, a key U.N. climate conference in Paris produced an international agreement to try to limit global warming to 2 degrees C , and preferably 1.5 degrees C, above preindustrial levels.

Every country has its own approach to the challenge of addressing climate change. In the United States, which gets approximately 80 percent of its energy from fossil fuels, sophisticated efforts to downplay and critique the science led to major delays in climate action. For decades U.S. fossil fuel companies such as ExxonMobil worked to influence politicians to take as little action on emissions reductions as possible. Working with a small group of influential scientists, this well-funded, well-orchestrated campaign took many of its tactics from earlier tobacco-industry efforts to cast doubt on the links between smoking and cancer, as historians Naomi Oreskes and Erik Conway documented in their book Merchants of Doubt.

Perhaps the peak of U.S. climate denialism came in the late 1980s and into the 1990s — roughly a century after Swedish physical chemist Svante Arrhenius laid out the consequences of putting too much carbon dioxide into the atmosphere. In 1988 NASA scientist James Hansen testified to lawmakers about the consequences of global warming. “It is already happening now,” Hansen said, summarizing what scientists had long known.

The high-profile nature of Hansen’s testimony, combined with his NASA expertise, vaulted global warming into the public eye in the United States like never before. “It really hit home with a public who could understand that there are reasons that Venus is hot and Mars is cold,” says Joshua Howe, a historian at Reed College. “And that if you use that same reasoning, we have some concerns about what is happening here on Earth.” But Hansen also kicked off a series of bitter public battles about the reality of human-caused climate change that raged for years.

One common approach of climate skeptics was to attack the environmental data and models that underlie climate science. In 1998, scientist Michael Mann, then at the University of Massachusetts–Amherst, and colleagues published a detailed temperature record that formed the basis of what came to be known as the “hockey stick” graph, so named because the chart showed a sharp rise in temperatures (the hockey blade) at the end of a long, much flatter period (the hockey stick). Skeptics soon demanded the data and software processing tools Mann used to create the graph. Bloggers and self-proclaimed citizen scientists created a cottage industry of questioning new climate science papers under the guise of “audits.” In 2009 hackers broke into a server at the University of East Anglia, a leading climate-research hub in Norwich, England, and released more than 1,000 e-mails between climate scientists. This “Climategate” scandal purported to reveal misconduct on the part of the researchers, but several reviews largely exonerated the scientists.

The graph that launched climate skeptic attacks

This famous graph, produced by scientist Michael Mann and colleagues, and then reproduced in a 2001 report by the Intergovernmental Panel on Climate Change, dramatically captures temperature change over time. Climate change skeptics made it the center of an all-out attack on climate science.

Such tactics undoubtedly succeeded in feeding politicians’ delay on climate action in the United States, most of it from Republicans. President George W. Bush withdrew the country from the Kyoto Protocol in 2001 ; Donald Trump similarly rejected the Paris accord in 2017 . As late as 2015, the chair of the Senate’s environment committee, James Inhofe of Oklahoma, brought a snowball into Congress on a cold winter’s day in order to continue his argument that human-caused global warming is a “hoax.” In Australia, a similar mix of right-wing denialism and fossil fuel interests has kept climate change commitments in flux, as prime ministers are voted in and out over fierce debates about how the nation should act on climate.

Yet other nations have moved forward. Some European countries such as Germany aggressively pursued renewable energies, such as wind and solar, while activists such as the Swedish teenager Greta Thunberg — the vanguard of a youth-action movement — pressured their governments for more.

In recent years the developing economies of China and India have taken center stage in discussions about climate action. Both nations argue that they must be allowed extra time to wean themselves off fossil fuels in order to continue economic growth. They note that historically speaking, the United States is the largest total emitter of carbon by far.

Total carbon dioxide emissions by country, 1850–2021

These 20 nations have emitted the largest cumulative amounts of carbon dioxide since 1850. Emissions are shown in in billions of metric tons and are broken down into subtotals from fossil fuel use and cement manufacturing (blue) as well as from land use and forestry (green).

China, whose annual CO 2 emissions surpassed those of the United States in 2006, declared several moderate steps in 2021 to reduce emissions, including that it would stop building coal-burning power plants overseas. India announced it would aim for net-zero emissions by 2070, the first time it has set a date for this goal.

Yet such pledges continue to be criticized. At the 2021 U.N. Climate Change Conference in Glasgow, Scotland, India was globally criticized for not committing to a complete phaseout of coal — although the two top emitters, China and the United States, have not themselves committed to phasing out coal. “There is no equity in this,” says Aayushi Awasthy, an energy economist at the University of East Anglia. — Alexandra Witze

Facing a warmer future

Climate change creeps up gradually on society, except when it doesn’t. The slow increase in sea level, for instance, causes waters to lap incrementally higher at shorelines year after year. But when a big storm comes along — which may be happening more frequently due to climate change — the consequences become much more obvious. Storm surge rapidly swamps communities and wreaks disproportionate havoc. That’s why New York City installed floodgates in its subway and tunnel system in the wake of 2012’s Superstorm Sandy , and why the Pacific island nation of Tuvalu has asked Australia and New Zealand to be prepared to take in refugees fleeing from rising sea levels.

The list of climate impacts goes on and on — and in many cases, changes are coming faster than scientists had envisioned a few decades ago. The oceans are becoming more acidic as they absorb carbon dioxide, harming tiny marine organisms that build protective calcium carbonate shells and are the base of the marine food web. Warmer waters are bleaching coral reefs. Higher temperatures are driving animal and plant species into areas in which they previously did not live, increasing the risk of extinction for many. “It’s no longer about impacts in the future,” says Rachel Cleetus, a climate policy expert at the Union of Concerned Scientists. “It’s about what’s happening in the U.S. here and now, and around the world.”

No place on the planet is unaffected. In many areas, higher temperatures have led to major droughts, which dry out vegetation and provide additional fuel for wildfires such as those that have devastated Australia , the Mediterranean and western North America in recent years. The Colorado River , the source of water for tens of millions of people in the western United States , came under a water-shortage alert in 2021 for the first time in history.

Then there’s the Arctic, where temperatures are rising at more than twice the global average and communities are at the forefront of change. Permafrost is thawing, destabilizing buildings, pipelines and roads. Caribou and reindeer herders worry about the increased risk of parasites to the health of their animals. With less sea ice available to buffer the coast from storm erosion, the Inupiat village of Shishmaref, Alaska, risks crumbling into the sea. It will need to move from its sand-barrier island to the mainland .

“We know these changes are happening and that the Titanic is sinking,” says Louise Farquharson, a geomorphologist at the University of Alaska in Fairbanks who monitors permafrost and coastal change around Alaska. Like many Arctic scientists, she is working with Indigenous communities to understand the shifts they’re experiencing and what can be done when buildings start to slump and water supplies start to drain away. “A big part is just listening to community members and understanding what they’re seeing change,” she says.

All around the planet, those who depend on intact ecosystems for their survival face the greatest threat from climate change. And those with the least resources to adapt to climate change are the ones who feel it first .

“We are going to warm,” says Claudia Tebaldi, a climate scientist at Lawrence Berkeley National Laboratory in California. “There is no question about it. The only thing that we can hope to do is to warm a little more slowly.”

That’s one reason why the IPCC report released in 2021 focuses on anticipated levels of global warming. There is a big difference between the planet warming 1.5 degrees versus 2 degrees or 2.5 degrees. Consider that we are now at least 1.1 degrees above preindustrial levels of CO 2 and are already seeing dramatic shifts in climate. Given that, keeping further global temperature increases as low as possible will make a big difference in the climate impacts the planet faces. “With every fraction of a degree of warming, everything gets a little more intense,” says paleoclimatologist Jessica Tierney. “There’s no more time to beat around the bush.”

Historical and projected global temperature change

Various scenarios for how greenhouse gas emissions might change going forward help scientists predict future climate change. This graph shows the simulated historical temperature trend along with future projections of global surface temperature based on five scenarios from the Intergovernmental Panel on Climate Change. Temperature change is the difference from the 1850–1900 average.

The future rests on how much nations are willing to commit to cutting emissions and whether they will stick to those commitments. It’s a geopolitical balancing act the likes of which the world has never seen.

Science can and must play a role going forward. Improved climate models will illuminate what changes are expected at the regional scale, helping officials prepare. Governments and industry have crucial parts to play as well. They can invest in technologies, such as carbon sequestration, to help decarbonize the economy and shift society toward more renewable sources of energy. “We can solve these problems — most of the tools are already there,” says Cascade Tuholske, a geographer at Columbia University. “We just have to do it.”

Huge questions remain. Do voters have the will to demand significant energy transitions from their governments? How can business and military leaders play a bigger role in driving climate action? What should be the role of low-carbon energy sources that come with downsides, such as nuclear energy ? How can developing nations achieve a better standard of living for their people while not becoming big greenhouse gas emitters? How can we keep the most vulnerable from being disproportionately harmed during extreme events, and incorporate environmental and social justice into our future?

These questions become more pressing each year, as CO 2 accumulates in our atmosphere. The planet is now at higher levels of CO 2 than at any time in the last 3 million years. Yet Ralph Keeling, keeper of the iconic Mauna Loa record tracking the rise in atmospheric CO 2 , is already optimistically thinking about how scientists would be able to detect a slowdown, should the world actually start cutting emissions by a few percent per year. “That’s what the policy makers want to see — that there’s been some large-scale impact of what they did,” he says.

At the 2021 U.N. climate meeting in Glasgow diplomats from around the world agreed to work more urgently to shift away from using fossil fuels. They did not, however, adopt targets strict enough to keep the world below a warming of 1.5 degrees Celsius. It’s been well over a century since Svante Arrhenius recognized the consequences of putting extra carbon dioxide into the atmosphere, and yet world leaders have yet to pull together to avoid the most dangerous consequences of climate change.

Time is running out. — Alexandra Witze

Climate change facts

We know that climate change and its consequences are real, and we are responsible. Here’s what the science tells us.

How much has the planet warmed over the past century?

The planet’s average surface temperature has risen by at least 1.1 degree Celsius since preindustrial levels of 1850–1900.

What is causing climate change?

People are loading the atmosphere with carbon dioxide and other heat-trapping gases produced during the burning of fossil fuels, such as coal and gas, and cutting down forests.

What are some of the effects of climate change?

Ice sheets in Greenland and Antarctica are melting, raising sea levels and flooding low-lying island nations and coastal cities. Drought is parching farmlands and the rivers that feed them. Wildfires are raging. Rains are becoming more intense, and weather patterns are shifting.

What is the greenhouse effect?

In the 19th century, Irish physicist John Tyndall found that carbon dioxide gas, as well as water vapor, absorbed more heat than air alone. He argued that such gases would trap heat in Earth’s atmosphere, much as panes of glass trap heat in a greenhouse, and thus modulate climate.

What is the Keeling curve?

line graph showing increasing monthly average CO2 concentrations at Mauna Loa Observatory from 1958 to 2022

One of the most iconic datasets in all of science, the Keeling curve tracks the rise of atmospheric CO 2 . When geochemist Charles David Keeling began his measurements in 1958 on the Hawaiian volcano of Mauna Loa, CO 2 made up 315 parts per million of the global atmosphere. Each year the curve keeps going up: In 2016 it passed 400 ppm of CO 2 in the atmosphere, as measured during its typical annual minimum in September. In 2021, the annual minimum was 413 ppm.

Does it get hotter every year?

Average global temperatures fluctuate from year to year, but temperature observations taken at weather stations around the world confirm that we are living in the hottest years on record. The 10 warmest years since record keeping began in 1880 have all occurred since 2005. And nine of those 10 have come since 2010.

What countries emit the most carbon dioxide?

The United States has been the largest total emitter of carbon dioxide by far, followed by China and Russia. China’s annual CO 2 emissions surpassed those of the United States in 2006.

What places are impacted by climate change?

No place on the planet is unaffected. Higher temperatures have led to major droughts, providing fuel for wildfires such as those that have devastated Australia , the Mediterranean and western North America in recent years. The Colorado River came under a water-shortage alert in 2021 for the first time in history. In the Arctic, where temperatures are rising at more than twice the global average, permafrost is thawing, destabilizing buildings, pipelines and roads. With less sea ice available to buffer the coast from storm erosion, the Inupiat village of Shishmaref, Alaska, risks crumbling into the sea. All around the planet, those who depend on intact ecosystems for their survival face the greatest threat from climate change. And those with the least resources to adapt to climate change are the ones who feel it first .

Essay on Climate Change

Climate Change Essay - The globe is growing increasingly sensitive to climate change. It is currently a serious worldwide concern. The term "Climate Change" describes changes to the earth's climate. It explains the atmospheric changes that have occurred across time, spanning from decades to millions of years. Here are some sample essays on climate change.

100 Words Essay on Climate Change

200 words essay on climate change, 500 words essay on climate change.

The climatic conditions on Earth are changing due to climate change. Several internal and external variables, such as solar radiation, variations in the Earth's orbit, volcanic eruptions, plate tectonics, etc., are to blame for this.

There are strategies for climate change reduction. If not implemented, the weather might get worse, there might be water scarcity, there could be lower agricultural output, and it might affect people's ability to make a living. In order to breathe clean air and drink pure water, you must concentrate on limiting human activity. These are the simple measures that may be taken to safeguard the environment and its resources.

The climate of the Earth has changed significantly over time. While some of these changes were brought on by natural events like volcanic eruptions, floods, forest fires, etc., many of the changes were brought on by human activity. The burning of fossil fuels, domesticating livestock, and other human activities produce a significant quantity of greenhouse gases. This results in an increase of greenhouse effect and global warming which are the major causes for climate change.

Reasons of Climate Change

Some of the reasons of climate change are:

Deforestation

Excessive use of fossil fuels

Water and soil pollution

Plastic and other non biodegradable waste

Wildlife and nature extinction

Consequences of Climate Change

All kinds of life on earth will be affected by climate change if it continues to change at the same pace. The earth's temperature will increase, the monsoon patterns will shift, the sea level will rise, and there will be more frequent storms, volcano eruptions, and other natural calamities. The earth's biological and ecological equilibrium will be disturbed. Humans won't be able to access clean water or air to breathe when the environment becomes contaminated. The end of life on this earth is imminent. To reduce the issue of climate change, we need to bring social awareness along with strict measures to protect and preserve the natural environment.

A shift in the world's climatic pattern is referred to as climate change. Over the centuries, the climate pattern of our planet has undergone modifications. The amount of carbon dioxide in the atmosphere has significantly grown.

When Did Climate Change Begin

It is possible to see signs of climate change as early as the beginning of the industrial revolution. The pace at which the manufacturers produced things on a large scale required a significant amount of raw materials. Since the raw materials being transformed into finished products now have such huge potential for profit, these business models have spread quickly over the world. Hazardous substances and chemicals build up in the environment as a result of company emissions and waste disposal.

Although climate change is a natural occurrence, it is evident that human activity is turning into the primary cause of the current climate change situation. The major cause is the growing population. Natural resources are utilised more and more as a result of the population's fast growth placing a heavy burden on the available resources. Over time, as more and more products and services are created, pollution will eventually increase.

Causes of Climate Change

There are a number of factors that have contributed towards weather change in the past and continue to do so. Let us look at a few:

Solar Radiation |The climate of earth is determined by how quickly the sun's energy is absorbed and distributed throughout space. This energy is transmitted throughout the world by the winds, ocean currents etc which affects the climatic conditions of the world. Changes in solar intensity have an effect on the world's climate.

Deforestation | The atmosphere's carbon dioxide is stored by trees. As a result of their destruction, carbon dioxide builds up more quickly since there are no trees to absorb it. Additionally, trees release the carbon they stored when we burn them.

Agriculture | Many kinds of greenhouse gases are released into the atmosphere by growing crops and raising livestock. Animals, for instance, create methane, a greenhouse gas that is 30 times more potent than carbon dioxide. The nitrous oxide used in fertilisers is roughly 300 times more strong than carbon dioxide.

How to Prevent Climate Change

We need to look out for drastic steps to stop climate change since it is affecting the resources and life on our planet. We can stop climate change if the right solutions are put in place. Here are some strategies for reducing climate change:

Raising public awareness of climate change

Prohibiting tree-cutting and deforestation.

Ensure the surroundings are clean.

Refrain from using chemical fertilisers.

Water and other natural resource waste should be reduced.

Protect the animals and plants.

Purchase energy-efficient goods and equipment.

Increase the number of trees in the neighbourhood and its surroundings.

Follow the law and safeguard the environment's resources.

Reduce the amount of energy you use.

During the last few decades especially, climate change has grown to be of concern. Global concern has been raised over changes in the Earth's climatic pattern. The causes of climate change are numerous, as well as the effects of it and it is our responsibility as inhabitants of this planet to look after its well being and leave it in a better condition for future generations.

Essay on Global Warming

Updated on
Apr 27, 2024

Being able to write an essay is an integral part of mastering any language. Essays form an integral part of many academic and scholastic exams like the SAT , and UPSC amongst many others. It is a crucial evaluative part of English proficiency tests as well like IELTS , TOEFL , etc. Major essays are meant to emphasize public issues of concern that can have significant consequences on the world. To understand the concept of Global Warming and its causes and effects, we must first examine the many factors that influence the planet’s temperature and what this implies for the world’s future. Here’s an unbiased look at the essay on Global Warming and other essential related topics.

Short Essay on Global Warming and Climate Change?

Since the industrial and scientific revolutions, Earth’s resources have been gradually depleted. Furthermore, the start of the world’s population’s exponential expansion is particularly hard on the environment. Simply put, as the population’s need for consumption grows, so does the use of natural resources , as well as the waste generated by that consumption.

Climate change has been one of the most significant long-term consequences of this. Climate change is more than just the rise or fall of global temperatures; it also affects rain cycles, wind patterns, cyclone frequencies, sea levels, and other factors. It has an impact on all major life groupings on the planet.

What is Global Warming?

Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century, primarily due to the greenhouse gases released by people burning fossil fuels . The greenhouse gases consist of methane, nitrous oxide, ozone, carbon dioxide, water vapour, and chlorofluorocarbons. The weather prediction has been becoming more complex with every passing year, with seasons more indistinguishable, and the general temperatures hotter.

The number of hurricanes, cyclones, droughts, floods, etc., has risen steadily since the onset of the 21st century. The supervillain behind all these changes is Global Warming. The name is quite self-explanatory; it means the rise in the temperature of the Earth.

What are the Causes of Global Warming?

According to recent studies, many scientists believe the following are the primary four causes of global warming:

Deforestation
Greenhouse emissions
Carbon emissions per capita

Extreme global warming is causing natural disasters , which can be seen all around us. One of the causes of global warming is the extreme release of greenhouse gases that become trapped on the earth’s surface, causing the temperature to rise. Similarly, volcanoes contribute to global warming by spewing excessive CO2 into the atmosphere.

The increase in population is one of the major causes of Global Warming. This increase in population also leads to increased air pollution . Automobiles emit a lot of CO2, which remains in the atmosphere. This increase in population is also causing deforestation, which contributes to global warming.

The earth’s surface emits energy into the atmosphere in the form of heat, keeping the balance with the incoming energy. Global warming depletes the ozone layer, bringing about the end of the world. There is a clear indication that increased global warming will result in the extinction of all life on Earth’s surface.

Solutions for Global Warming

Of course, industries and multinational conglomerates emit more carbon than the average citizen. Nonetheless, activism and community effort are the only viable ways to slow the worsening effects of global warming. Furthermore, at the state or government level, world leaders must develop concrete plans and step-by-step programmes to ensure that no further harm is done to the environment in general.

Although we are almost too late to slow the rate of global warming, finding the right solution is critical. Everyone, from individuals to governments, must work together to find a solution to Global Warming. Some of the factors to consider are pollution control, population growth, and the use of natural resources.

One very important contribution you can make is to reduce your use of plastic. Plastic is the primary cause of global warming, and recycling it takes years. Another factor to consider is deforestation, which will aid in the control of global warming. More tree planting should be encouraged to green the environment. Certain rules should also govern industrialization. Building industries in green zones that affect plants and species should be prohibited.

Effects of Global Warming

Global warming is a real problem that many people want to disprove to gain political advantage. However, as global citizens, we must ensure that only the truth is presented in the media.

This decade has seen a significant impact from global warming. The two most common phenomena observed are glacier retreat and arctic shrinkage. Glaciers are rapidly melting. These are clear manifestations of climate change.

Another significant effect of global warming is the rise in sea level. Flooding is occurring in low-lying areas as a result of sea-level rise. Many countries have experienced extreme weather conditions. Every year, we have unusually heavy rain, extreme heat and cold, wildfires, and other natural disasters.

Similarly, as global warming continues, marine life is being severely impacted. This is causing the extinction of marine species as well as other problems. Furthermore, changes are expected in coral reefs, which will face extinction in the coming years. These effects will intensify in the coming years, effectively halting species expansion. Furthermore, humans will eventually feel the negative effects of Global Warming.

Essay on Global Warming Paragraph in 100 – 150 words

Global Warming is caused by the increase of carbon dioxide levels in the earth’s atmosphere and is a result of human activities that have been causing harm to our environment for the past few centuries now. Global Warming is something that can’t be ignored and steps have to be taken to tackle the situation globally. The average temperature is constantly rising by 1.5 degrees Celsius over the last few years.

The best method to prevent future damage to the earth, cutting down more forests should be banned and Afforestation should be encouraged. Start by planting trees near your homes and offices, participate in events, and teach the importance of planting trees. It is impossible to undo the damage but it is possible to stop further harm.

Essay on Global Warming in 250 Words

Over a long period, it is observed that the temperature of the earth is increasing. This affected wildlife, animals, humans, and every living organism on earth. Glaciers have been melting, and many countries have started water shortages, flooding, and erosion and all this is because of global warming.

No one can be blamed for global warming except for humans. Human activities such as gases released from power plants, transportation, and deforestation have increased gases such as carbon dioxide, CFCs, and other pollutants in the earth’s atmosphere. The main question is how can we control the current situation and build a better world for future generations. It starts with little steps by every individual.

Start using cloth bags made from sustainable materials for all shopping purposes, instead of using high-watt lights use energy-efficient bulbs, switch off the electricity, don’t waste water, abolish deforestation and encourage planting more trees. Shift the use of energy from petroleum or other fossil fuels to wind and solar energy. Instead of throwing out the old clothes donate them to someone so that it is recycled.

Donate old books, don’t waste paper. Above all, spread awareness about global warming. Every little thing a person does towards saving the earth will contribute in big or small amounts. We must learn that 1% effort is better than no effort. Pledge to take care of Mother Nature and speak up about global warming.

Essay on Global Warming in 500 Words

Global warming isn’t a prediction, it is happening! A person denying it or unaware of it is in the most simple terms complicit. Do we have another planet to live on? Unfortunately, we have been bestowed with this one planet only that can sustain life yet over the years we have turned a blind eye to the plight it is in. Global warming is not an abstract concept but a global phenomenon occurring ever so slowly even at this moment. Global Warming is a phenomenon that is occurring every minute resulting in a gradual increase in the Earth’s overall climate. Brought about by greenhouse gases that trap the solar radiation in the atmosphere, global warming can change the entire map of the earth, displacing areas, flooding many countries, and destroying multiple lifeforms. Extreme weather is a direct consequence of global warming but it is not an exhaustive consequence. There are virtually limitless effects of global warming which are all harmful to life on earth. The sea level is increasing by 0.12 inches per year worldwide. This is happening because of the melting of polar ice caps because of global warming. This has increased the frequency of floods in many lowland areas and has caused damage to coral reefs. The Arctic is one of the worst-hit areas affected by global warming. Air quality has been adversely affected and the acidity of the seawater has also increased causing severe damage to marine life forms. Severe natural disasters are brought about by global warming which has had dire effects on life and property. As long as mankind produces greenhouse gases, global warming will continue to accelerate. The consequences are felt at a much smaller scale which will increase to become drastic shortly. The power to save the day lies in the hands of humans, the need is to seize the day. Energy consumption should be reduced on an individual basis. Fuel-efficient cars and other electronics should be encouraged to reduce the wastage of energy sources. This will also improve air quality and reduce the concentration of greenhouse gases in the atmosphere. Global warming is an evil that can only be defeated when fought together. It is better late than never. If we all take steps today, we will have a much brighter future tomorrow. Global warming is the bane of our existence and various policies have come up worldwide to fight it but that is not enough. The actual difference is made when we work at an individual level to fight it. Understanding its import now is crucial before it becomes an irrevocable mistake. Exterminating global warming is of utmost importance and each one of us is as responsible for it as the next.

Essay on Global Warming UPSC

Always hear about global warming everywhere, but do we know what it is? The evil of the worst form, global warming is a phenomenon that can affect life more fatally. Global warming refers to the increase in the earth’s temperature as a result of various human activities. The planet is gradually getting hotter and threatening the existence of lifeforms on it. Despite being relentlessly studied and researched, global warming for the majority of the population remains an abstract concept of science. It is this concept that over the years has culminated in making global warming a stark reality and not a concept covered in books. Global warming is not caused by one sole reason that can be curbed. Multifarious factors cause global warming most of which are a part of an individual’s daily existence. Burning of fuels for cooking, in vehicles, and for other conventional uses, a large amount of greenhouse gases like carbon dioxide, and methane amongst many others is produced which accelerates global warming. Rampant deforestation also results in global warming as lesser green cover results in an increased presence of carbon dioxide in the atmosphere which is a greenhouse gas. Finding a solution to global warming is of immediate importance. Global warming is a phenomenon that has to be fought unitedly. Planting more trees can be the first step that can be taken toward warding off the severe consequences of global warming. Increasing the green cover will result in regulating the carbon cycle. There should be a shift from using nonrenewable energy to renewable energy such as wind or solar energy which causes less pollution and thereby hinder the acceleration of global warming. Reducing energy needs at an individual level and not wasting energy in any form is the most important step to be taken against global warming. The warning bells are tolling to awaken us from the deep slumber of complacency we have slipped into. Humans can fight against nature and it is high time we acknowledged that. With all our scientific progress and technological inventions, fighting off the negative effects of global warming is implausible. We have to remember that we do not inherit the earth from our ancestors but borrow it from our future generations and the responsibility lies on our shoulders to bequeath them a healthy planet for life to exist.

Climate Change and Global Warming Essay

Global Warming and Climate Change are two sides of the same coin. Both are interrelated with each other and are two issues of major concern worldwide. Greenhouse gases released such as carbon dioxide, CFCs, and other pollutants in the earth’s atmosphere cause Global Warming which leads to climate change. Black holes have started to form in the ozone layer that protects the earth from harmful ultraviolet rays.

Human activities have created climate change and global warming. Industrial waste and fumes are the major contributors to global warming.

Another factor affecting is the burning of fossil fuels, deforestation and also one of the reasons for climate change. Global warming has resulted in shrinking mountain glaciers in Antarctica, Greenland, and the Arctic and causing climate change. Switching from the use of fossil fuels to energy sources like wind and solar.

When buying any electronic appliance buy the best quality with energy savings stars. Don’t waste water and encourage rainwater harvesting in your community.

Student Essay Competition: Joint Approaches to the Climate and Biodiversity Crises

11 March 2021

We want to hear your thoughts on how we can tackle the climate and biodiversity crises. Submit your short essay (up to 1000 words) by 28 May 2021 for a chance to get published and win up to £100. The competition is open to postgraduate students across UCL.

There is growing recognition that accelerating climate change and mass biodiversity loss are mutually reinforcing challenges. Global warming is already putting massive pressure on vulnerable ecosystems, including coral reefs and the polar regions. Unless decisive climate action is taken, we could experience sudden and dramatic disruptions to key ecosystems as early as 2030.

In turn, the decline of biodiversity is making it more difficult to address the climate crisis . This is because biodiverse ecosystems, such as forests, mangroves or peatlands, act as significant natural carbon stores and also provide protection from extreme weather events and other adverse effects of global warming.

The implications for humans are immense. The combined challenge of climate change and ecosystem breakdown poses a multitude of interrelated risks, from food insecurity to the spread of infectious diseases . We are on a “ collision course with the laws of ecology ;” eroding the natural life support systems upon which human civilisation ultimately depends.

But there is also positive news. Because climate change and biodiversity loss are closely linked, we can address them together – in a way that simultaneously offers benefits to human communities. There is growing interest in policy interventions that work with nature to make societies more environmentally and socially sustainable. A move towards such integrated solutions could also help facilitate the achievement of the United Nations Sustainable Development Goals (SDGs).

We invite postgraduate students across UCL to share their thoughts on the challenges and opportunities ahead. Students from any discipline can participate. Essays should not exceed 1000 words. They should be aimed at (and accessible to) a general university audience.

The following list provides examples of the types of questions students might want to select for discussion. Authors are free to pose their own questions of a similar nature.

How can we best make sense of the interrelated challenges presented by climate change and biodiversity loss?
Where do we see compelling examples of community-based solutions that work with nature rather than against it?
What are the implications of accelerating global warming and biodiversity loss for the prospect of achieving the UN SDGs?
How can we effectively catalyse action to bring political reality into alignment with biophysical reality?
What kind of governance frameworks (local, national, regional and/or global) are needed to address climate change and biodiversity loss in an integrated manner?
How can societies become more resilient to the risks posed by a warmer, more volatile planet?
How can governments incentivise an ecologically and socially sustainable post-COVID-19 recovery?

The best three essays will be published on the website of the UCL Global Governance Institute. The author of the winning essay will receive £100. There will be prizes of £50 each for the two runner-up entries. The winning essays will also be circulated to a network of UCL colleagues and external experts working on the climate-biodiversity interface.

To participate, submit your essay as an attachment (in Word or PDF) to [email protected] by 28 May 2021. If you have any questions about the competition, please contact Julia Kreienkamp at [email protected] .

This essay competition is facilitated by a grant from UCL Grand Challenges and the UCL Global Engagement Office. It forms part of a wider project on “ A Shared Agenda for the United Nations Sustainable Development Goals on Biodiversity and Climate Change ,” hosted by the UCL Global Governance Institute.

Emily Pineo, "'Nature': An Ableist Concept"
Nyala Tolfree, "What Are You Wearing?"

Write an opinion essay in which you make a short, persuasive, evidence-based argument related to the climate crisis and the challenges of sustainability. The essay should be timely and newsworthy. It should be clear to the reader, explicitly or implicitly, why you are the one person to make this argument given your story, your passion for what you’re researching or learning, or your plans for the future. Your opinion essay should bring a new idea and new voice to the conversation. This prompt is intentionally open-ended, but you may choose a further focus within one of the following areas:

Climate justice and activism

Climate policy

Climate technology

A vision for New York City

My climate story

Formal requirements:

The essay should be between 750-1000 words.

Strong op-eds show familiarity with a public and academic conversation and are often in conversation with other writers. Given that, strong op-eds use evidence. You must cite your sources and include a Works Cited page using MLA citation. You must follow the NYU EWP standards for academic integrity, with the further stipulation that writers may not present text generated or translated by an Artificial Intelligence writing assistance tool as their own.

The essay must be your original work and cannot have been previously published, or be under contract to be published. (The essay can be a work completed in a course.)

Opinion essays due on Friday April 12 at 11:59 p.m.

The op-ed competition will award three (3) winners and recognize an additional three (3) honorable mentions. All winners will be invited to read from their work at an upcoming NYU event.

Prizes are:

Three cash prizes $500, $350, $200

Conversations with editors and writers of leading publications concerned with climate change (TBA)

Three Honorable Mentions: $50

Entries will be judged by professors from NYU's EWP. Top entries will be shared with editors from leading national publications that run feature opinion and editorial sections.

A minimum of three of the six prizes will be awarded to undergraduate submissions.

Entries will be first vetted to ensure they meet formal requirements (word count, citation, original work). Entries that do not meet these requirements will not be considered for a prize. Entries that meet these requirements will be scored on the following criteria:

Originality and urgency: The essay brings something new to the conversation in climate change and sustainability; the argument is timely and newsworthy.

Voice and motive: The essay is written in a compelling voice; we understand why the writer is writing the essay; we understand they have good reasons for doing so.

Evidence-based claims: The essay makes claims grounded in well-sourced evidence and logical analysis.

Structure: The essay has a well-defined beginning, middle, and end, with effective transitions between sections, paragraphs, and sentences.

Writing style: The essay follows genre conventions of the op-ed, short paragraphs, and sentences that are clear, concise, correct, and free of jargon.

What is an Op-Ed? Why write one?

Writers across and beyond academia write opinion essays (aka op-eds, editorials) to make urgent public arguments. The best examples of op-eds are clear, concise, persuasive, evidence-based, and, above all, written in the writer’s distinctive voice. In a good op-ed, the writer anticipates readers and avoids jargon. Sometimes, opinion essays are professional in tone and written in the third-person. Sometimes, opinion essays are informal and draw intensely on the writer’s personal stories. They often, but do not always, conclude with a call to action or thought, asking the reader to do or think something new.

The goal of an opinion essay, per long-time former New York Times opinion editor David Shipley, is for the writer to bring a new idea and fresh perspective to a publication’s audience. (You can read his essay here .) Through syndication and social media, opinion essays have the potential to be read far beyond their original publication. And so you, as a writer, have the potential for your voice and ideas to reach the world.

To learn more about how to write a climate opinion essay, you are welcome to view these interactive slides from a free online workshop that was hosted by the NYU Expository Writing Program on Wednesday, March 27. These slides contain links to useful tips about how to meet the competition criteria, as well as links to strong example opinion essays and other resources.

The climate crisis is real – but overusing terms like ‘crisis’ and ‘emergency’ comes with risk

Bahasa Indonesia

“Crisis” is an incredibly potent word, so it’s interesting to witness the way the phrase “climate crisis” has become part of the lingua franca .

Once associated only with a few “outspoken” scientists and activists, the phrase has now gone mainstream.

But what do people understand by the term “climate crisis”? And why does it matter?

The mainstreaming of crisis-talk

It’s not only activists or scientists sounding the alarm.

UN Secretary General Antonio Guterres now routinely employs dramatic phrases like “digging our own graves” when discussing climate. Bill Gates advises us to avoid “climate disaster”.

This linguistic mainstreaming marks redrawn battle lines in the “climate wars”.

Denialism is in retreat. The climate change debate now is about what is to be done and by whom?

Scientists, using the full authority of their profession, have been key to changing the discourse. The lead authors of Intergovernmental Panel on Climate Change (IPCC) reports now pull no punches, talking openly about mass starvation, extinctions and disasters.

Read more: An official welcome to the Anthropocene epoch – but who gets to decide it's here?

These public figures clearly hope to jolt citizens, businesses and governments into radical climate action.

But for many ordinary folks, climate change can seem remote from everyday life. It’s not a “crisis” in the immediate way the pandemic has been.

Of course, many believe climate experts have understated the problem for too long.

And yet the new ubiquity of siren terms like climate “crisis”, “emergency”, “disaster”, “breakdown” and “calamity” does not guarantee any shared, let alone credible, understanding of their possible meaning.

This matters because such terms tend to polarise.

Few now doubt the reality of climate change. But how we describe its implications can easily repeat earlier stand-offs between “believers” and “sceptics”; “realists’ and "scare-mongerers”. The result is yet more political inertia and gridlock.

We will need to do better.

Four ideas for a new way forward

Terms like “climate crisis” are here to stay. But scientists, teachers and politicians need to be savvy. A keen awareness of what other people may think when they hear us shout “crisis!” can lead to better communication.

Here are four ideas to keep in mind.

1. We must challenge dystopian and salvation narratives

A crisis is when things fall apart. We see news reports of crises daily – floods in Pakistan, economic collapse in Sri Lanka, famine in parts of Africa.

But “climate crisis” signifies something that feels beyond the range of ordinary experience, especially to the wealthy. People quickly reach for culturally available ideas to fill the vacuum.

One is the notion of an all-encompassing societal break down, where only a few survive. Cormac McCarthy’s bleak book The Road is one example.

Central to many apocalyptic narratives is the idea technology and a few brave people (usually men) can save the day in the nick of time, as in films like Interstellar .

The problem, of course, is these (often fanciful) depictions aren’t suitable ways to interpret what climate scientists have been warning people about. The world is far more complicated.

2. We must bring the climate crisis home and make it present now

Even if they’re willing to acknowledge it as a looming crisis, many think climate change impacts will be predominantly felt elsewhere or in the distant future.

The disappearance of Tuvalu as sea levels rise is an existential crisis for its citizens but may seem a remote, albeit tragic, problem to people in Chicago, Oslo or Cape Town.

But the recent floods in eastern Australia and the heatwave in Europe allow a powerful point to be made: no place is immune from extreme weather as the planet heats up.

There won’t be a one-size-fits-all global climate crisis as per many Hollywood movies. Instead, people must understand global warming will trigger myriad local-to-regional scale crises.

Many will be on the doorstep, many will last for years or decades. Most will be made worse if we don’t act now. Getting people to understand this is crucial.

3. We must explain: a crisis in relation to what?

The climate wars showed us value disputes get transposed into arguments about scientific evidence and its interpretation.

A crisis occurs when events are judged in light of certain values, such as people’s right to adequate food, healthcare and shelter.

Pronouncements of crisis need to explain the values that underpin judgements about unacceptable risk, harm and loss.

Historians, philosophers, legal scholars and others help us to think clearly about our values and what exactly we mean when we say “crisis”.

4. We must appreciate other crises and challenges matter more to many people

Some are tempted to occupy the moral high ground and imply the climate crisis is so grand as to eclipse all others. This is understandable but imprudent.

It’s important to respect other perspectives and negotiate a way forward. Consider, for example, the way author Bjørn Lomborg has questioned the climate emergency by arguing it’s not the main threat.

Lomborg was widely pilloried. But his arguments resonated with many. We may disagree with him, but his views are not irrational.

We must seek to understand how and why this kind of argument makes sense to so many people.

Words matter. It’s vital terms like “crisis” and “calamity” don’t become rhetorical devices devoid of real content as we argue about what climate action to take.

Climate Change Essay

500+ words essay on climate change.

Climate change is the shift of weather patterns and conditions. We are experiencing rapid change in the climate due to various factors. Needless to say, our earth is experiencing rising global temperatures. Do you think it is a matter of concern? Well yes, you might have heard about the melting glaciers which is resulting in rising sea levels. There has been a drastic change in the climate due to hazardous factors such as pollution, burning coals, industrial waste disposal in the air, etc. All this will result in affecting the environment and its resources. To overcome the issue of climate change, you need to bring social awareness along with stringent measures to protect and preserve the environment. In this climate change essay, we are going to discuss the factors and how to prevent climate change.

What is Climate Change?

Climate change is the change in the average weather conditions. We can say that climate change is responsible for change in the normal climatic conditions. These changes result in heavy storms, heat waves, floods, melting glaciers, etc. Our earth is going through a lot of changes with respect to climate, which is impacting the livelihood of people and other living things. Global warming is one aspect of climate change. Due to these factors, carbon dioxide and greenhouse gases are released in the atmosphere. Check out the following causes of climate change given below.

Climate Change Factors Essay

Nowadays, we experience extreme weather conditions whether it is cold, heat or rain. Some of the forces or factors that contribute to climate change are greenhouse gas emission, burning of coal, deforestation, air pollution, industrial gas, etc. These factors lead to major climatic change in the earth. Did you know that climate change leads to disastrous events? Yes, it affects the livelihood, health and the resources. It also impacts the water, air and the land we live in. It leads to extreme weather conditions such as droughts, heavy rain, floods, storms, heat waves, forest fires, etc. Moreover, it reduces the quality of drinking water, damages property, pollutes the air and also leads to loss of life. Additionally, it is impacting the life of flora and fauna around us. We need to take extreme measures to prevent climate change.

How To Prevent Climate Change Essay

As climate change is hampering the lives and resources of our earth, we need to look out for extreme measures to prevent climate change. Now, what can we do to prevent this? Is it possible for all of us to join and preserve nature? Yes, we can if appropriate strategies are implemented to combat climate change. The different ways to reduce climate change are mentioned below:

Make policies and agreements on climate change.
Implement projects on clean energy.
Create social awareness on climate change.
Prohibit deforestation and cutting down trees.
Conduct capacity building programs on climate change.
Keep the surroundings clean.
Avoid use of chemical fertilizers.
Reduce wastage of water and other natural resources.
Protect the flora and fauna.
Buy energy efficient products and appliances.
Plant more trees in the neighbourhood and surrounding areas.
Respect the environment and protect its resources.
Reduce the consumption of energy.

These are the ways to reduce climate change. If not implemented, you might see an increase in the weather conditions, shortage of drinking water, agricultural yields, and impact on livelihood. Therefore, you must focus on reducing anthropogenic activities so that you can breathe fresh air and drink clean water. These are the small steps to protect the environment and its resources.

Causes and Effects of Climate Change

Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions.

As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded history. Warmer temperatures over time are changing weather patterns and disrupting the usual balance of nature. This poses many risks to human beings and all other forms of life on Earth.

Causes of Climate Change

Generating power

Generating electricity and heat by burning fossil fuels causes a large chunk of global emissions. Most electricity is still generated by burning coal, oil, or gas, which produces carbon dioxide and nitrous oxide – powerful greenhouse gases that blanket the Earth and trap the sun’s heat. Globally, a bit more than a quarter of electricity comes from wind, solar and other renewable sources which, as opposed to fossil fuels, emit little to no greenhouse gases or pollutants into the air.

Manufacturing goods

Manufacturing and industry produce emissions, mostly from burning fossil fuels to produce energy for making things like cement, iron, steel, electronics, plastics, clothes, and other goods. Mining and other industrial processes also release gases, as does the construction industry. Machines used in the manufacturing process often run on coal, oil, or gas; and some materials, like plastics, are made from chemicals sourced from fossil fuels. The manufacturing industry is one of the largest contributors to greenhouse gas emissions worldwide.

Cutting down forests

Cutting down forests to create farms or pastures, or for other reasons, causes emissions, since trees, when they are cut, release the carbon they have been storing. Each year approximately 12 million hectares of forest are destroyed. Since forests absorb carbon dioxide, destroying them also limits nature’s ability to keep emissions out of the atmosphere. Deforestation, together with agriculture and other land use changes, is responsible for roughly a quarter of global greenhouse gas emissions.

Using transportation

Most cars, trucks, ships, and planes run on fossil fuels. That makes transportation a major contributor of greenhouse gases, especially carbon-dioxide emissions. Road vehicles account for the largest part, due to the combustion of petroleum-based products, like gasoline, in internal combustion engines. But emissions from ships and planes continue to grow. Transport accounts for nearly one quarter of global energy-related carbon-dioxide emissions. And trends point to a significant increase in energy use for transport over the coming years.

Producing food

Producing food causes emissions of carbon dioxide, methane, and other greenhouse gases in various ways, including through deforestation and clearing of land for agriculture and grazing, digestion by cows and sheep, the production and use of fertilizers and manure for growing crops, and the use of energy to run farm equipment or fishing boats, usually with fossil fuels. All this makes food production a major contributor to climate change. And greenhouse gas emissions also come from packaging and distributing food.

Powering buildings

Globally, residential and commercial buildings consume over half of all electricity. As they continue to draw on coal, oil, and natural gas for heating and cooling, they emit significant quantities of greenhouse gas emissions. Growing energy demand for heating and cooling, with rising air-conditioner ownership, as well as increased electricity consumption for lighting, appliances, and connected devices, has contributed to a rise in energy-related carbon-dioxide emissions from buildings in recent years.

Consuming too much

Your home and use of power, how you move around, what you eat and how much you throw away all contribute to greenhouse gas emissions. So does the consumption of goods such as clothing, electronics, and plastics. A large chunk of global greenhouse gas emissions are linked to private households. Our lifestyles have a profound impact on our planet. The wealthiest bear the greatest responsibility: the richest 1 per cent of the global population combined account for more greenhouse gas emissions than the poorest 50 per cent.

Based on various UN sources

Effects of Climate Change

Hotter temperatures

As greenhouse gas concentrations rise, so does the global surface temperature. The last decade, 2011-2020, is the warmest on record. Since the 1980s, each decade has been warmer than the previous one. Nearly all land areas are seeing more hot days and heat waves. Higher temperatures increase heat-related illnesses and make working outdoors more difficult. Wildfires start more easily and spread more rapidly when conditions are hotter. Temperatures in the Arctic have warmed at least twice as fast as the global average.

More severe storms

Destructive storms have become more intense and more frequent in many regions. As temperatures rise, more moisture evaporates, which exacerbates extreme rainfall and flooding, causing more destructive storms. The frequency and extent of tropical storms is also affected by the warming ocean. Cyclones, hurricanes, and typhoons feed on warm waters at the ocean surface. Such storms often destroy homes and communities, causing deaths and huge economic losses.

Increased drought

Climate change is changing water availability, making it scarcer in more regions. Global warming exacerbates water shortages in already water-stressed regions and is leading to an increased risk of agricultural droughts affecting crops, and ecological droughts increasing the vulnerability of ecosystems. Droughts can also stir destructive sand and dust storms that can move billions of tons of sand across continents. Deserts are expanding, reducing land for growing food. Many people now face the threat of not having enough water on a regular basis.

A warming, rising ocean

The ocean soaks up most of the heat from global warming. The rate at which the ocean is warming strongly increased over the past two decades, across all depths of the ocean. As the ocean warms, its volume increases since water expands as it gets warmer. Melting ice sheets also cause sea levels to rise, threatening coastal and island communities. In addition, the ocean absorbs carbon dioxide, keeping it from the atmosphere. But more carbon dioxide makes the ocean more acidic, which endangers marine life and coral reefs.

Loss of species

Climate change poses risks to the survival of species on land and in the ocean. These risks increase as temperatures climb. Exacerbated by climate change, the world is losing species at a rate 1,000 times greater than at any other time in recorded human history. One million species are at risk of becoming extinct within the next few decades. Forest fires, extreme weather, and invasive pests and diseases are among many threats related to climate change. Some species will be able to relocate and survive, but others will not.

Not enough food

Changes in the climate and increases in extreme weather events are among the reasons behind a global rise in hunger and poor nutrition. Fisheries, crops, and livestock may be destroyed or become less productive. With the ocean becoming more acidic, marine resources that feed billions of people are at risk. Changes in snow and ice cover in many Arctic regions have disrupted food supplies from herding, hunting, and fishing. Heat stress can diminish water and grasslands for grazing, causing declining crop yields and affecting livestock.

More health risks

Climate change is the single biggest health threat facing humanity. Climate impacts are already harming health, through air pollution, disease, extreme weather events, forced displacement, pressures on mental health, and increased hunger and poor nutrition in places where people cannot grow or find sufficient food. Every year, environmental factors take the lives of around 13 million people. Changing weather patterns are expanding diseases, and extreme weather events increase deaths and make it difficult for health care systems to keep up.

Poverty and displacement

Climate change increases the factors that put and keep people in poverty. Floods may sweep away urban slums, destroying homes and livelihoods. Heat can make it difficult to work in outdoor jobs. Water scarcity may affect crops. Over the past decade (2010–2019), weather-related events displaced an estimated 23.1 million people on average each year, leaving many more vulnerable to poverty. Most refugees come from countries that are most vulnerable and least ready to adapt to the impacts of climate change.

Climate change: An A-Z glossary of the words you need to know in the fight against global warming

Political reporter @alixculbertson

Friday 29 October 2021 09:45, UK

Climate change affects everybody on this planet, so it is important to know all the terminology surrounding it.

Here are some of the most important words and phrases:

Changes in processes, practices and structures to help cope with the effects of climate change - such as building flood defences or switching to drought-resistant crops.

Flood defences, like this temporary one on the River Severn, are a type of climate change adaptation

Biodiversity

A wide range of living organisms, such as animals and plants, in an environment. Biodiversity is essential for ecosystems to survive. For example, without plants, there would be no oxygen - and without bees to pollinate, there would be no fruit or nuts.

Biomass/biofuel

Biomass is any organic matter that comes from plants and animals, such as cow dung, corn crops or wood chips that can be used for renewable energy.

Biofuel is the fuel derived from biomass. The UK considers biofuel renewable, but some scientists say it is not as it emits CO2.

Carbon budget

The amount of CO2 that a country, company or organisation has agreed is the most it will produce in a particular period of time to meet emission reduction commitments.

Carbon capture/sequestration and storage

The collection and transport of concentrated CO2 gas from large emission sources, such as power plants.

Those gases are then injected into deep underground reservoirs. Geological sequestration is another name for carbon capture.

This carbon capture unit at the Mountaineer coal power plant in West Virginia, US, stores CO2 from the plant

Carbon intensity

The amount of carbon, by weight, emitted per unit of energy consumed.

Carbon markets

One country pays for carbon emissions to be reduced in another country so the first country can count those reductions towards its own national targets.

This can also be at regional or company level, with those who are going to exceed a greenhouse gas cap are able to trade allowance from a company that will not reach the cap.

Project trading can also happen with carbon offsetting (see below).

Carbon offsetting/credits

The practice of reducing CO2 or other greenhouse gas emissions made in one area to compensate for emissions elsewhere.

This could be planting trees for taking a plane and often involves a company funding a project elsewhere - restoring forests or developing renewable energy, for example.

The amount those producing carbon must pay for each tonne of greenhouse gas emissions.

CO2e (carbon dioxide equivalent)

A standard unit for measuring the impact of each different greenhouse gas in terms of the amount of CO2 that would create the same amount of warming.

Climate change

The long-term changes in the Earth's climate, or a region on Earth, including variations in sea levels, amounts of snow and sea ice.

Climate finance

Local, national or transnational financing that seeks to support mitigation and adaptation actions to address climate change.

The Paris Agreement (scroll down) calls for financial assistance from those with more financial resources than those that are poorer and more vulnerable.

Climate justice

Looking at the climate crisis through a human rights lens instead of a purely scientific one.

It puts people and communities most vulnerable to the impact of climate change at its heart.

The 26th UN Climate Change Conference due to take place in Glasgow from 1 to 12 November 2021. COP stands for Conference of the Parties.

It will bring world leaders together to agree on what actions need to be taken to achieve the Paris Agreement goals and those of the UN Framework Convention on Climate Change.

The different energy sources used in a geographical region, and in what proportions - often split into renewable (such as wind, solar and tidal) and non-renewable (such as gas and coal).

Wind farms such as Burbo Bank in Liverpool Bay, UK, produce renewable energy

Energy transition

The global energy sector's shift from fossil-based energy production and consumption to renewable energy.

Fast fashion

Cheap, often poor quality clothes produced rapidly by mass-market retailers in response to the latest trends. They are bought regularly and are often only worn a few times before being thrown out.

Global warming

A gradual increase in the Earth's overall temperature caused by increased levels of greenhouse gases such as CO2, CFCs and other pollutants that absorb infrared radiation.

Greenwashing

Disinformation produced by an organisation to present an environmentally responsible public image.

The UN's Intergovernmental Panel on Climate Change. It was created to provide politicians with regular scientific assessments on climate change, its implications and potential future risks and to put forward adaptation and mitigation options.

Actions to limit global warming by reducing human emissions of greenhouse gases into the atmosphere and reducing their concentrations.

Electric cars are a form of climate change mitigation as they reduce human-induced CO2 emissions

Nationally determined contributions of each of the Paris Agreement's signatories.

They are national climate plans highlighting climate actions, including targets, policies and measures aimed at reducing climate change.

Net zero/absolute zero/carbon neutrality

All terms for when the amount of CO2 emissions released on an annual basis is zero or negative.

Paris Agreement

A legally binding international treaty on climate change adopted by 196 parties at COP21 in Paris in 2015.

Its goal is to limit global warming to well below 2C, preferably to 1.5C, below pre-industrial levels.

Every five years, countries must submit their plans for climate action (NDCs) and in 2020 they had to submit a long-term plan.

The United Nations Framework Convention on Climate Change is an international environmental treaty addressing climate change.

It was signed by 154 states at the Earth Summit in Rio de Janeiro in 1992 with the aim of stabilising greenhouse gas concentrations to prevent dangerous human-induced interference with the climate system.

ENVIRONMENT

The world's plastic pollution crisis, explained

Much of the planet is swimming in discarded plastic, which is harming animal and possibly human health. Can it be cleaned up?

Plastic pollution has become one of the most pressing environmental issues , as rapidly increasing production of disposable plastic products overwhelms the world’s ability to deal with them. Plastic pollution is most visible in developing Asian and African nations, where garbage collection systems are often inefficient or nonexistent. But the developed world, especially in countries with low recycling rates , also has trouble properly collecting discarded plastics. Plastic trash has become so ubiquitous it has prompted efforts to write a global treaty negotiated by the United Nations.

Why was plastic invented?

Plastics made from fossil fuels are just over a century old. Production and development of thousands of new plastic products accelerated after World War II, so transforming the modern age that life without plastics would be unrecognizable today. In plastic, inventors found a light, durable material that can be used in everything from transportation to medicine.

Plastics revolutionized medicine with life-saving devices, made space travel possible, lightened cars and jets—saving fuel and pollution—and saved lives with helmets, incubators, and equipment for clean drinking water.

The conveniences plastics offer, however, led to a throw-away culture that reveals the material’s dark side: today, single-use plastics account for 40 percent of the plastic produced every year. Many of these products, such as plastic bags and food wrappers, have a lifespan of mere minutes to hours, yet they may persist in the environment for hundreds of years.

Plastics by the numbers

Some key facts:

Half of all plastics ever manufactured have been made in the last 20 years.
Production increased exponentially, from 2.3 million tons in 1950 to 448 million tons by 2015. Production is expected to double by 2050.
Every year, about eight million tons of plastic waste escapes into the oceans from coastal nations. That’s the equivalent of setting five garbage bags full of trash on every foot of coastline around the world.
Plastics often contain additives making them stronger, more flexible, and durable. But many of these additives can extend the life of products if they become litter, with some estimates ranging to at least 400 years to break down.

How plastics move around the world

Most of the plastic trash in the oceans, Earth’s last sink, flows from land. Trash is also carried to sea by major rivers , which act as conveyor belts, picking up more and more trash as they move downstream. Once at sea, much of the plastic trash remains in coastal waters. But once caught up in ocean currents, it can be transported around the world.

On Henderson Island , an uninhabited atoll in the Pitcairn Group isolated halfway between Chile and New Zealand, scientists found plastic items from Russia, the United States, Europe, South America, Japan, and China. They were carried to the South Pacific by the South Pacific gyre, a circular ocean current.

Microplastics—a new health threat

Once at sea, sunlight, wind, and wave action break down plastic waste into small particles, often less than one-fifth of an inch across. These so-called microplastics are spread throughout the water column and have been found in every corner of the globe, from Mount Everest, the highest peak, to the Mariana Trench , the deepest trough.

The world’s nations agree to fix the plastic waste crisis

How a dramatic win in plastic waste case may curb ocean pollution

The Haunting Art of Plastic Pollution

Microplastics are breaking down further into smaller and smaller pieces. Plastic microfibers, meanwhile, have been found in municipal drinking water systems and drifting through the air.

It's no surprise then that scientists have found microplastics in people. The tiny particles are in our blood, lungs, and even in feces . Exactly how much microplastics might be harming human health is a question scientists are urgently trying to answer. ( Learn more. )

Harm to wildlife

Millions of animals are killed by plastics every year, from birds to fish to other marine organisms. Nearly 700 species, including endangered ones, are known to have been affected by plastics. Nearly every species of seabird eats plastics.

Most of the deaths to animals are caused by entanglement or starvation. Seals, whales , turtles, and other animals are strangled by abandoned fishing gear or discarded six-pack rings . Microplastics have been found in more than 100 aquatic species, including fish, shrimp, and mussels destined for our dinner plates. In many cases, these tiny bits pass through the digestive system and are expelled without consequence. But plastics have also been found to have blocked digestive tracts or pierced organs, causing death. Stomachs so packed with plastics reduce the urge to eat, causing starvation.

Plastics have been consumed by land-based animals, including elephants, hyenas, zebras, tigers, camels, cattle, and other large mammals, in some cases causing death .

Tests have also confirmed liver and cell damage and disruptions to reproductive systems, prompting some species, such as oysters, to produce fewer eggs. New research shows that larval fish are eating nanofibers in the first days of life, raising new questions about the effects of plastics on fish populations.

Stopping plastic pollution

Once in the ocean, it is difficult—if not impossible—to retrieve plastic waste. Mechanical systems, such as Mr. Trash Wheel , a litter interceptor in Maryland’s Baltimore Harbor, can be effective at picking up large pieces of plastic, such as foam cups and food containers, from inland waters. But once plastics break down into microplastics and drift throughout the water column in the open ocean, they are virtually impossible to recover.

The solution is to prevent plastic waste from entering rivers and seas in the first place, many scientists and conservationists—including the National Geographic Society —say. This could be accomplished with improved waste management systems and recycling , better product design that takes into account the short life of disposable packaging, and a reduction in manufacturing of unnecessary single-use plastics.

We Made Plastic. We Depend on It. Now We’re Drowning in It.

The Stench of Climate Change Denial

A person making a face indicating that there’s an unpleasant smell in the air.

By Paul Krugman

Opinion Columnist

This may sound a bit weird, but when I think about my adolescent years, I sometimes associate them with the faint smell of sewage.

You see, when I was in high school, my family lived on the South Shore of Long Island, where few homes had sewer connections. Most had septic tanks, and there always seemed to be an overflowing tank somewhere upwind.

Most of Nassau County eventually got sewered . But many American homes, especially in the Southeast, aren’t connected to sewer lines, and more and more septic tanks are overflowing, on a scale vastly greater than what I remember from my vaguely smelly hometown — which is both disgusting and a threat to public health.

The cause? Climate change. Along the Gulf and South Atlantic coasts, The Washington Post reported last week, “sea levels have risen at least six inches since 2010.” This may not sound like much, but it leads to rising groundwater and elevated risks of overflowing tanks.

The emerging sewage crisis is only one of many disasters we can expect as the planet continues to warm, and nowhere near the top of the list. But it seems to me to offer an especially graphic illustration of two points. First, the damage from climate change is likely to be more severe than even pessimists have tended to believe. Second, mitigation and adjustment — which are going to be necessary, because we’d still be headed for major effects of climate change even if we took immediate action to greatly reduce greenhouse gas emissions — will probably be far more difficult, as a political matter, than it should be.

On the first point: Estimating the costs of climate change and, relatedly, the costs polluters impose every time they emit another ton of carbon dioxide requires fusing results from two disciplines. On one side, we need physical scientists to figure out how much greenhouse gas emissions will warm the planet, how this will change weather patterns and so on. On the other, we need economists to estimate how these physical changes will affect productivity, health care costs and more.

Land Squeeze: The hidden battle for Africa’s soils

Land grabbing is not just back with a vengeance. It is taking on new guises such as carbon offsets, green hydrogen schemes, and other “green grabs”.

In recent years, Africa has been at the epicentre of an alarming global trend: the land squeeze . The 2007-8 global financial crisis unleashed a huge wave of land grabbing across Africa and the world. Though the crisis eased, the pressures on farmland never went away. Now 15 years on, global land prices have doubled, land grabbing is back with a vengeance, and farmers are being squeezed from all sides.

As a major report by IPES-Food reveals , today’s land squeeze is escalating dangerously in new and varying forms – including for carbon and biodiversity offsetting schemes, financialisation and speculation, resource grabs, expanding mines and mega-developments, and ever-more industrial food systems. We are seeing a new rush for land that is displacing small-scale farmers, Indigenous Peoples, pastoralists, and rural communities – or removing their control over their land. The consequences are dire, exacerbating rural poverty, food insecurity, and land inequality across the continent – and putting the future of small-scale farming at risk.

Land isn’t just dirt beneath our feet: it’s the bedrock of our food systems keeping us all fed. It is not like any other commodity to be bought and sold. It is the basis of diverse cultures, livelihoods, and rural traditions for millions of Africans. It is a home to biodiversity. Yet, according to the Land Matrix Initiative , Africa is at the forefront of the land grab crisis in the Global South, with nearly 1,000 large-scale land deals for agriculture recorded across the continent since 2000. Mozambique is worst affected with 110 large-scale agricultural land deals, followed by Ethiopia, Cameroon, and the Democratic Republic of Congo (DRC).

The land rush is not merely for agricultural purposes. This time it’s also being driven by “green grabs” where governments and powerful corporations appropriate land for dubious tree planting, carbon sequestration, and biofuel and green hydrogen schemes (requiring large amounts of water). These activities, masquerading as environmental initiatives, are ultimately bad for climate and sustainability, as they shift the burden for cutting carbon emissions from Global North polluters onto Africa’s lands. They do this while directly threatening the very communities bearing the brunt of climate change by displacing local land users and farmers. Already 20% of large land deals are “green grabs”, often targeting indigenous lands – and this could soar in the coming years. Governments’ pledges for land-based carbon removals worldwide already add up to almost 1.2 billion hectares of land – about as much land as is used to grow crops worldwide today.

“Green grabs” bring new powerful actors into Africa’s finely balanced land dynamics – creating a dangerous interface between small-scale farmers and rich governments, fossil fuels companies, large conservation groups, and real estate developers.

Take Blue Carbon, a Dubai-based firm backed by the ruling royal family that is buying up the rights to forests and farmland in order to trade carbon offsets. Blue Carbon has acquired some 25 million hectares of African land through agreements with the governments of five countries: including for 20% of Zimbabwe’s land , 10% of Liberia, and swathes of Kenya, Tanzania, and Zambia. Pastoralist and indigenous communities are particularly at risk. In Kenya, the forceful relocation of up to 700 members of the Ogiek People has been reported in connection with Blue Carbon’s investments. In Liberia, local leaders have denounced the lack of any consultation since the Memorandum of Understanding was signed.

The land squeeze also involves rampant encroachment for mining, urbanisation, and mega-developments. Prime agricultural land continues to be lost to rising urbanisation and large-scale infrastructure projects, leading to degradation and loss of biodiversity.

This is also a problem for our food security. A 2018 report showed that large-scale land deals in Ethiopia and Ghana are forcing smallholder farmers to become wage labourers, downsize onto smaller fragmented plots, or migrate to cities – undermining their ability to feed themselves and their communities. Around 90% of large-scale land deals divert land from local food production to producing biofuels, cash crops for export, mining oil, gas and minerals, or carbon offsetting. The vague terms of these deals exacerbate risks to smallholders and food availability.

The land squeeze is not just an environmental crisis; it’s a fight for justice and survival. This widespread appropriation of land underscores the urgent need for equitable and sustainable land governance across Africa. Transformative action is needed. Policymakers must protect and include local communities as part of climate change mitigation and biodiversity protection, supporting them to steward the land, rather than displacing them. This can be achieved by:

Removing speculative capital and financial actors from land markets to get land back into the hands of farmers. This should include capping land acquisitions, giving farmers first right of refusal, and cracking down on bogus land-based carbon offsets.
Incorporating the Right to Land in countries’ constitutions and environmental and agricultural policies – including in climate plans (Nationally Determined Contributions [NDCs]) and biodiversity strategies.
Establishing inclusive land and food systems governance to halt green grabs and re-centre communities. New mechanisms must place local communities and human rights at the heart of land governance. Democratic spatial planning and accountable land agencies are essential for this.
Making community-managed land conversation systems the flagship tool of the Global Biodiversity Framework to meet global biodiversity goals while protecting local food production.

Africa’s smallholders, pastoralists, and Indigenous communities are the stewards of its land and biodiversity. Their inclusion and empowerment are vital to feeding Africa, as well as to climate action – yet they lack rights and social protections. The powerful new “carbon colonialism” fights the climate crisis against communities rather than with them.

Bold action and leadership are needed to ensure farmers and communities have meaningful and equitable access to land. Africa’s land is not just an economic asset to be sold to the highest bidder. By empowering local communities and safeguarding their lands, we can pave the way for a sustainable and equitable future for all Africans.

The Jamaicans have an expression that you can’t clap with one hand. Reading this article, it suggested to me that the acquisition of land in Africa achieved by some kind of invasion. A physical appropriation. Comment or as you call it a land grab, by some kind of invading force. There is no mention in your article about the role of the various governments throughout Africa who have seen fit to sell off THEIR land? Your use of the word colonialism is provocative And suggests to me that the whole purpose of your article was to somehow imply that. these land transactions were some form of neocolonialism. In so doing, you have ignored the fundamental fact that these deals could only be achieved with the cooperation or collaboration of the various governments in Africa. But you make no mention of that fact. That devalues the whole article in my opinion.
