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.

The Climate Crisis – A Race We Can Win

Climate change is the defining crisis of our time and it is happening even more quickly than we feared. But we are far from powerless in the face of this global threat. As Secretary-General António Guterres pointed out in September, “the climate emergency is a race we are losing, but it is a race we can win”.

No corner of the globe is immune from the devastating consequences of climate change. Rising temperatures are fueling environmental degradation, natural disasters, weather extremes, food and water insecurity, economic disruption, conflict, and terrorism. Sea levels are rising, the Arctic is melting, coral reefs are dying, oceans are acidifying, and forests are burning. It is clear that business as usual is not good enough. As the infinite cost of climate change reaches irreversible highs, now is the time for bold collective action.

GLOBAL TEMPERATURES ARE RISING

Billions of tons of CO2 are released into the atmosphere every year as a result of coal, oil, and gas production. Human activity is producing greenhouse gas emissions at a record high , with no signs of slowing down. According to a ten-year summary of UNEP Emission Gap reports, we are on track to maintain a “business as usual” trajectory.

The last four years were the four hottest on record. According to a September 2019 World Meteorological Organization (WMO) report, we are at least one degree Celsius above preindustrial levels and close to what scientists warn would be “an unacceptable risk”. The 2015 Paris Agreement on climate change calls for holding eventual warming “well below” two degrees Celsius, and for the pursuit of efforts to limit the increase even further, to 1.5 degrees. But if we don’t slow global emissions, temperatures could rise to above three degrees Celsius by 2100 , causing further irreversible damage to our ecosystems.

Glaciers and ice sheets in polar and mountain regions are already melting faster than ever, causing sea levels to rise. Almost two-thirds of the world’s cities   with populations of over five million are located in areas at risk of sea level rise and almost 40 per cent of the world’s population live within 100 km of a coast. If no action is taken, entire districts of New York, Shanghai, Abu Dhabi, Osaka, Rio de Janeiro, and many other cities could find themselves underwater within our lifetimes , displacing millions of people.

FOOD AND WATER INSECURITY

Global warming impacts everyone’s food and water security. Climate change is a direct cause of soil degradation, which limits the amount of carbon the earth is able to contain. Some 500 million people today live in areas affected by erosion, while up to 30 per cent of food is lost or wasted as a result. Meanwhile, climate change limits the availability and quality of water for drinking and agriculture.

In many regions, crops that have thrived for centuries are struggling to survive, making food security more precarious. Such impacts tend to fall primarily on the poor and vulnerable. Global warming is likely to make economic output between the world’s richest and poorest countries grow wider .

NEW EXTREMES

Disasters linked to climate and weather extremes have always been part of our Earth’s system. But they are becoming more frequent and intense as the world warms. No continent is left untouched, with heatwaves, droughts, typhoons, and hurricanes causing mass destruction around the world. 90 per cent   of disasters are now classed as weather- and climate-related, costing the world economy 520 billion USD each year , while 26 million people are pushed into poverty as a result.

A CATALYST FOR CONFLICT

Climate change is a major threat to international peace and security. The effects of climate change heighten competition for resources such as land, food, and water, fueling socioeconomic tensions and, increasingly often, leading to mass displacement .

Climate is a risk multiplier   that makes worse already existing challenges. Droughts in Africa and Latin America directly feed into political unrest and violence. The World Bank estimates that, in the absence of action, more than 140 million people in Sub-Saharan Africa, Latin America, and South Asia will be forced to migrate within their regions by 2050.

A PATH FORWARD

While science tells us that climate change is irrefutable, it also tells us that it is not too late to stem the tide. This will require fundamental transformations in all aspects of society — how we grow food, use land, transport goods, and power our economies.

While technology has contributed to climate change, new and efficient technologies can help us reduce net emissions and create a cleaner world. Readily-available technological solutions already exist for more than 70 per cent   of today’s emissions. In many places renewable energy is now the cheapest energy source and electric cars are poised to become mainstream.

In the meantime, nature-based solutions provide ‘breathing room’ while we tackle the decarbonization of our economy. These solutions allow us to mitigate a portion of our carbon footprint while also supporting vital ecosystem services, biodiversity, access to fresh water, improved livelihoods, healthy diets, and food security. Nature-based solutions include improved agricultural practices, land restoration, conservation, and the greening of food supply chains.

Scalable new technologies and nature-based solutions will enable us all to leapfrog to a cleaner, more resilient world. If governments, businesses, civil society, youth, and academia work together, we can create a green future where suffering is diminished, justice is upheld, and harmony is restored between people and planet.

Responding to the Climate Threat: Essays on Humanity’s Greatest Challenge

A new book co-authored by MIT Joint Program Founding Co-Director Emeritus Henry Jacoby

From the Back Cover

This book demonstrates how robust and evolving science can be relevant to public discourse about climate policy. Fighting climate change is the ultimate societal challenge, and the difficulty is not just in the wrenching adjustments required to cut greenhouse emissions and to respond to change already under way. A second and equally important difficulty is ensuring widespread public understanding of the natural and social science. This understanding is essential for an effective risk management strategy at a planetary scale. The scientific, economic, and policy aspects of climate change are already a challenge to communicate, without factoring in the distractions and deflections from organized programs of misinformation and denial. 

Here, four scholars, each with decades of research on the climate threat, take on the task of explaining our current understanding of the climate threat and what can be done about it, in lay language―importantly, without losing critical  aspects of the natural and social science. In a series of essays, published during the 2020 presidential election, the COVID pandemic, and through the fall of 2021, they explain the essential components of the challenge, countering the forces of distrust of the science and opposition to a vigorous national response.  

Each of the essays provides an opportunity to learn about a particular aspect of climate science and policy within the complex context of current events. The overall volume is more than the sum of its individual articles. Proceeding each essay is an explanation of the context in which it was written, followed by observation of what has happened since its first publication. In addition to its discussion of topical issues in modern climate science, the book also explores science communication to a broad audience. Its authors are not only scientists – they are also teachers, using current events to teach when people are listening. For preserving Earth’s planetary life support system, science and teaching are essential. Advancing both is an unending task.

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.

4.  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.

5.  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.

6.  “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.

7.  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.

8.  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.

9.  “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.”

10.  “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.”

11.  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.

12.  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.

13.  “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.” !

14.  “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.”

15.  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.

Century of Science: Theme

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.

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.”

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.

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.

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?

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 .

Climate Change ‘Biggest Threat Modern Humans Have Ever Faced’, World-Renowned Naturalist Tells Security Council, Calls for Greater Global Cooperation

Climate change is a “crisis multiplier” that has profound implications for international peace and stability, Secretary-General António Guterres told the Security Council today, amid calls for deep partnerships within and beyond the United Nations system to blunt its acute effects on food security, natural resources and migration patterns fuelling tensions across countries and regions.

Throughout the morning, the Council’s high-level open debate on climate and security heard from a range of influential voices, including naturalist David Attenborough, who called climate change “the biggest threat to security that modern humans have ever faced”.  In video remarks telecast at the outset, he warned that concentrations of carbon dioxide currently in the atmosphere have not been equalled for millions of years.

“If we continue on our current path, we will face the collapse of everything that gives us our security,” he said:  food production, access to fresh water, habitable ambient temperature and ocean food chains.  The poorest — those with the least security — are certain to suffer.  “Our duty right now is surely to do all we can to help those in the most immediate danger.”

While the world will never return to the stable climate that gave birth to civilization, he said that, if Governments attending the twenty-sixth Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in November recognize climate change as a global security threat, “we may yet act proportionately — and in time”.

Climate change can only be dealt with by unparalleled levels of global cooperation, he said.  It will compel countries to question economic models, invent new industries and recognize the moral responsibility that wealthy nations have to the rest of the world, placing a value on nature that “goes far beyond money”.  He challenged the international community to finally create a stable, healthy world where resources are equally shared and where — for the first time in history — people “come to know what it feels like to be secure”.

Mr. Guterres echoed those calls, describing the climate emergency as “the defining issue of our time”.  Noting that the last decade was the hottest in human history, he said wildfires, cyclones, floods and droughts are now the new normal.  “These shocks not only damage the environment on which we depend, they also weaken our political, economic and social systems,” he said.

Indeed, where climate change dries up rivers, reduces harvests, destroys critical infrastructure and displaces communities, it exacerbates the risks of conflict, he said.  A study by the Stockholm International Peace Research Institute found that 8 of the 10 countries hosting the largest multilateral peace operations in 2018 were in areas highly exposed to climate change.

The impact is greatest where fragility and conflict have weakened coping mechanisms, he said, where people depend on natural capital for their livelihoods and where women — who bear the greatest burden of the climate emergency — do not enjoy equal rights.  He highlighted examples in Afghanistan, where reduced harvests have pushed people into poverty, leaving them susceptible to recruitment by armed groups, and across West Africa and the Sahel, where changes in grazing patterns have fostered conflict between pastoralists and farmers.  In some Pacific small island nations, entire communities have been forced to relocate.

“The forced movement of larger numbers of people around the world will clearly increase the potential for conflict and insecurity,” he observed.  He called for greater efforts to address climate‑related security risks, starting with a focus on prevention, and creating a global coalition committed to achieving net-zero emissions by mid-century.  The United Nations is asking companies, cities and financial institutions to prepare credible decarbonization plans.

In addition, immediate actions are needed to protect countries from increasingly frequent and severe climate effects.  He urged donors and multilateral and national development banks to increase the share of adaptation and resilience finance to at least 50 per cent of their climate finance support.  Developed countries, too, must keep their pledge to channel $100 billion annually to the global South.  “They have already missed the deadline of 2020,” he acknowledged.

Above all, he called for embracing a concept of security that places people at its centre, stressing that COVID-19 has laid bare the devastation that non‑traditional security threats can cause on a global scale.  In all such efforts, it will be essential to build on the strengths of the Security Council, Peacebuilding Commission, international financial institutions, regional organizations, civil society, the private sector, academia and others.

Issuing a call to action, Nisreen Elsaim, Chair of the Youth Organization on Climate Change and the United Nations Youth Advisory Group, said young people around the globe are watching the Security Council as it grapples with climate change.  Each of the organ’s four meetings on the issue — in 2007, 2011, 2018 and 2019 — have referenced serious climate-related security risks in Somalia, Darfur, West Africa and the Sahel, Mali and the Lake Chad Basin.  “Science has forecasted many more countries will join this list if we did not take the right measures now, and if we did not start adaptation specially in Africa,” she said, adding that, in her country, “we are living in continuous insecurity due to many factors that put Sudan on the top of the list when it comes to climate vulnerability”.

She recalled that, in a 2018 Council resolution on Sudan, members recognized the adverse effects of climate change, ecological changes and natural hazards on the situation in Darfur, focusing specifically on drought, desertification, land degradation and food insecurity.  “Human survival, in a situation of resources degradation, hunger, poverty and uncontrolled climate migration, will make conflict an inevitable result,” she said.  Moreover, climate-related emergencies cause major disruptions in access to health, life-saving sexual and reproductive health services, and result in loss of livelihoods and drive displacement and migration.  They also increase the risk of gender-based violence and harmful practices and force young people to flee in search of a decent life.

Welcoming the Council’s recent deployment of a new special political mission, the United Nations Integrated Transition Assistance Mission in the Sudan (UNITAMS), she said it has a historic opportunity to speak to the root causes of the conflict.  Climate change and youth participation is mentioned twice in the Mission’s mandate, and climate change challenges are included in the 2020 Juba Peace Agreement.  Emphasizing that young people must be part of the solution, she declared:  “We are the present, we have the future, let’s not repeat previous generations’ lapse.”

In the ensuing dialogue, Heads of State and Government, along with ministers and other senior officials described national actions to attenuate the negative impact of climate change and offered their views on the related security risks.  Some pressed the Council to broaden its thinking about non-traditional security threats.  Several — including leaders from Kenya and Niger — stressed that the link between climate and conflict could not be more evident, while others explored the ability of Governments to meet people’s basic needs, and still others cast doubt on the assertion that the relationship between climate and conflict is causal, instead pointing to political and economic factors that are known to drive tensions.

Boris Johnson, Prime Minister of the United Kingdom and Council President for February, speaking in his national capacity, said the Council, while imperfect, has been willing to lead the way in confronting threats to international security.  “That is exactly what climate change represents,” he said, acknowledging that, while there are some who disagree, these cynics “could not be more wrong”.  While the causes of climate change may not sit within the Council’s traditional purview, its effects most certainly do.  He asked delegates to consider the young man forced onto the road when his once‑fertile home becomes a desert — one of the 16 million people displaced by weather-related disasters each year — who becomes easy prey for violent extremists, or the girl who drops out of school because her daily search for water takes her away from her family — and into the sights of the human traffickers.

“If such scenes were triggered by the actions of some despotic warlord or internecine conflict, few would question this Council’s right to act or its duty to do so,” he assured.  “This is not a subject from which we should shy away.”  The world must move from 51 billion metric tons of greenhouse‑gas emissions each year to net zero, so that the increase in global temperatures remains within manageable levels.  For its part, the United Kingdom Parliament passed a law committing to net zero by 2050, he said, drawing attention to his pledge that the nation would slash emissions by 68 per cent by 2030.  He urged the Council to act, “because climate change is a geopolitical issue every bit as much as an environmental one”, stressing that, if it is to succeed in maintaining peace and security worldwide, it must galvanize and support the United Nations family of agencies into a swift and effective response.

Kaïs Saïed, President of Tunisia , agreed with Ms. Elsaim that the world must listen to youth on climate change.  More broadly, humans — and not money — must be placed at the centre of the issue.  Voicing support for the Secretary-General’s 2021 priorities, especially his efforts to galvanize Member States to confront the multiple impacts of climate change, he described it as ironic that humans are, at the same time, the phenomenon’s drivers and its greatest victims.  “It is no one’s right to […] to commit all of humanity to death,” he stressed, noting that Council resolution 2532 (2020) confirmed that insecurity can be driven by a multitude of factors, not just armed conflict.  One such driver is the deepening poverty and resource scarcity resulting from a changing climate, particularly in Africa.  Climate factors often prolong conflict and create conditions conducive to deprivation, exclusion, terrorism and organized crime.

Calling on the Council to adopt a new, more comprehensive approach and for sufficient resources for all specialized agencies related to climate change, he underlined the need for early warning systems and better prevention strategies.  Noting that the COVID-19 pandemic and other recent crises have once again revealed the need for States to strengthen their solidarity, he emphasized the need for prompt action while stressing that the burden borne by States must be differentiated based on their degree of responsibility for causing the crisis.  Moreover, mitigation cannot be at the expense of developing countries, he said.

Uhuru Kenyatta, President of Kenya , said that new approaches to investment by the public and private sector need to reach the countries and regions worst hit by climate change.  Persistent droughts, constant sea‑level rise and increasingly frequent extreme weather patterns are reversing economic growth and development gains achieved over decades.  The result is increased fragility to instability and armed conflict that then come to the attention of this Security Council.  The implementation of the Council’s mandate to maintain global peace and security will only get more difficult with time if climate change remains on its present course.  Rather than wait for a future tipping point, we must redouble the efforts to direct all the resources and multilateral frameworks of our rules-based international order to mitigate the effects of climate change.  While the bulk of this work is happening outside the Council, no body with such a strong mandate should step aside from this challenge.

The climate-security nexus is already impacting Africa.  “Listen to us Africans when we tell you that the link is clear, its impact tangible and the need for solutions urgent,” he said.  Making recommendations, he said that the Council must do more when crafting mandates for conflict resolution and post-conflict resolution to ensure they dovetail with the efforts to deploy climate change mitigation and adaptation measures.  In this regard, he applauded Council resolutions 2349 (2017) and 2502 (2019), respectively on Lake Chad and the Democratic Republic of the Congo, that have integrated measures to address the impact of climate change.  The 15-member organ can also act strongly against illicit financial outflows, illicit resource exploitation, terrorism financing and money‑laundering in the most fragile regions in Africa.  Doing so immediately boosts the resources available to Governments to undertake climate change mitigation and offer the public services and goods needed to consolidate and protect peace.

Brigi Rafini, Prime Minister of Niger , agreed that the impact of climate change on peace and security is increasingly evident, stressing that water scarcity exacerbated by climate change could see gross domestic product (GDP) in the Sahel fall by 6 per cent and hunger increase 20 per cent by 2050.  Climate change has increased competition for diminished land and water resources, ramping up tensions between livestock owners and others.  He underscored the collective responsibility to tackle this existential challenge, stressing that “climate change and land degradation are no longer purely environmental matters”.  Rather, they are part of a broader view that links environmental goals with those for economic and social development, and the pursuit of international peace and stability.

“We need to consider climate change as a threat to peace and security,” he said, urging the Council to shore up its understanding of impact on security and to systematically consider climate change in its resolutions pertaining to specific country and regional contexts.  In such efforts, it should rely on the advisory role of the Peacebuilding Commission, and the Informal Expert Group on Climate and Security, co-chaired by Niger and Ireland.  The appointment of a Special Envoy of the Secretary-General for Climate and Security likewise will raise the profile of this dimension within the Council’s work.

Nguyễn Xuân Phúc, Prime Minister of Viet Nam , said the Earth’s recent calamities have placed great burdens on the political and socioeconomic life of many countries, causing unemployment and poverty, creating instability and exacerbating current conflicts.  Against that backdrop, the Council should galvanize the international community’s collective efforts with an approach that is balanced between traditional and non-traditional security challenges.  That includes addressing the root causes of conflicts such as poverty, inequality, power politics and unilateral interference and coercion.

Calling for strict adherence to the Charter of the United Nations and international law, he said the 2030 Agenda for Sustainable Development, the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement on climate change must guide the way, and greater resources are needed to support developing countries, least developed countries, small island developing States and landlocked countries.  The Council should also enhance its early warning capacity, bolster its mediation and conflict prevention roles, work more closely with regional organizations and fully respect States’ sovereignty and national ownership.  Noting that Viet Nam is among the six countries most severely affected by climate change, he outlined various national efforts to address the challenge while requesting more international assistance.

Erna Solberg, Prime Minister of Norway , emphasized that climate change is redefining the global security landscape.  “We must rethink and adapt the Council’s approaches to peacebuilding and sustaining peace in three ways,” she said.  First, the Council needs better information on climate-related security risks.  International research networks and the informal expert group will be important in that regard.  Norway has helped establish a Nordic-Baltic expert network.  Second, the Council should discuss climate risks in specific country contexts, based on country reporting and briefings.  The United Nations must be at the forefront of preventive diplomacy.  To achieve sustainable solutions, peace diplomacy must be climate-sensitive, and climate action must be conflict‑sensitive.  Third, it is imperative to strengthen partnerships within and beyond the United Nations system, including with affected States and regional organizations.  The active participation of diverse groups, including women and youth, is also vital.

The national security communities in many countries have understood the security risks posed by climate change, she continued.  While climate change can lead to hard security challenges, there are no hard security solutions.  The first line of defence is ambitious climate action.  It must begin with the full implementation of the Paris Agreement and 2030 Agenda.  Climate action depends on multilateral cooperation.  By shouldering a common responsibility to counter climate change, the Council will be better prepared to maintain international peace and stability.

Ralph E. Gonsalves, Prime Minister and Minister for Foreign Affairs of Saint Vincent and the Grenadines , emphasizing that the Council has a responsibility to address the consequences of climate change, said a failure to do so would be, in part, “an abdication of our duty”.  It is time for the organ to seriously consider drafting a resolution on the matter and to map out a coherent approach, aiming for a working consensus.  Affirming UNFCCC’s role as the primary body for dealing with climate change and the Paris Agreement as a major part of the rules-based international system, he said the Council should play its role without encroaching on the work of UNFCCC’s inclusive decision-making body.  It should also engage with the Peacebuilding Commission and the General Assembly on climate and security risks that touch on issues of humanitarian support, sustainable development, health pandemics, peace and security.

Stressing that the first step to prevent or contain climate-security risks is for the major, and historical, emitters to fulfil — and indeed exceed — the commitments made in the Paris Agreement, he underlined the principle of common but differentiated responsibility.  Climate change is an existential threat that disproportionately affects the most vulnerable, especially small island developing States such as Saint Vincent and the Grenadines.  “It has become distressingly commonplace for an entire year’s [gross domestic product] to be washed away by a hurricane overnight, even as we are hindered by a lack of a sufficient inclusion, on favourable terms, into the global financial architecture,” he said.  Citing the many natural hazards in Haiti, in particular, he also drew attention to the Sahel region and the battle for dwindling resources.  However, no country is immune to such human-made challenges and all must stand in solidarity, with the Council paying close attention to climate change as it crafts its mandates, he said.

Kaja Kallas, Prime Minister of Estonia , said 7 of the 10 countries most vulnerable and least prepared to deal with climate change host a United Nations peacekeeping operation or a special political mission — a fact the Council cannot ignore.  She expressed support for the statement to be delivered by Germany’s Foreign Minister on behalf of like-minded countries pointing the way forward for the Council, stressing that “we need to acknowledge that the climate emergency can pose a danger to peace — and we must make it a part of our security policy planning and discussions here”.  She pressed the Council to “do more” to fully

aspects of its work, noting that the Secretary-General must receive a mandate to collect data and coordinate policy to this aim.

Among other efforts, she said that Estonia cooperates with small island States and least developed countries in green technology solutions and know-how transfer.  The Government also recently launched the Data for the Environment Alliance, a coalition of State and non-State actors that will support the United Nations Environment Programme (UNEP) in developing a global environmental data strategy by 2025.

Simon Coveney, Minister for Foreign Affairs and Defence of Ireland , said that climate change has many complex impacts, not least on international peace and security, the very business of this Council.  Climate change is already causing upheaval, affecting peace and security and the stability of societies.  Pointing out that the relationship between climate and security works in complex ways, he said political instability undermines efforts to build climate resilience, and the impact of climactic shocks is compounded when institutions are strained.  Ireland is proud to join the Weathering Risk Project to help guide action at the Security Council and beyond, and is keen to understand better not just how climate change contributes to insecurity but how climate action can build peace.  Ireland chairs the Informal Expert Group of Member States on this topic, together with Niger, also partnering with Nauru and Germany, as Chairs of the Group of Friends on Climate and Security.

Ireland’s core message today is that the inclusion of climate in Council discussions and actions will strengthen conflict prevention and support peacebuilding efforts.  Stressing the need to ensure the full, equal and meaningful participation of women and youth in decision-making processes related to climate issues and the management of natural resources, he declared:  “But, in listening to and understanding the concerns and insights of future generations, we cannot abrogate our responsibility to provide leadership today”.

Marcelo Ebrard Casaubón, Minister for Foreign Affairs of Mexico , said the COVID-19 pandemic has revealed that international peace and security can no longer be viewed through a single lens, but must also consider multiple drivers of insecurity.  Food insecurity, water scarcity and droughts — all exacerbated by climate change — have reached severe levels in several regions of the world.  Pledging Mexico’s support to the next Conference of Parties to the UNFCCC in Glasgow, later in 2021, he said climate change requires a comprehensive global response with a focus on ecosystem preservations.  Mexico recently submitted its own national plan in that arena, which is coupled with a focus on prevention and adaptation, as well as efforts to reduce inequality and strengthen communities.  Stressing that all efforts must be taken in line with the 2030 Agenda, he welcomed the Council’s creation of an informal group to monitor the links between climate and peace and security as a timely measure.  Underlining the importance of ensuring sustainable peacebuilding and protecting livelihoods, he agreed with the Secretary-General that post-pandemic recovery efforts are an opportunity to “build back better” and build more egalitarian, adaptable societies.

Emmanuel Macron, President of France , said protecting the environment has, in recent years, meant recognizing climate change as a peace and security issue.  Of the 20 countries most affected by conflict in the world, 12 are also severely impacted by climate change, he said, spotlighting the impacts of desertification, the increase in forced migration and agricultural challenges — all of which have resulted in such fallout as the advent of climate refugees and growing conflicts over land and water.  Endorsing the initiative to address such matters under the auspices of the Council, he echoed calls for the appointment of a United Nations Special Envoy for Climate Security, as well as for an annual Secretary-General’s report with relevant recommendations.

Recognizing that the effects of climate change are unfairly distributed worldwide, he recalled his recent call for France’s contribution to the Green Climate Fund to be increased to one third of its total.  France strongly supports the creation of a “Great Green Wall” in Africa, which aims to restore 250 million hectares of land for agriculture, create 10 million green new jobs and sequester carbon.  He also pledged France’s commitment to accelerating the preservation of biodiversity, while calling for strengthened dialogue between the African Union and the United Nations on climate and security.  Turning to the Pacific, where many nations are struggling to implement mitigation measures, he called for additional international support and an easing of geopolitical tensions across the region.

Prakash Javadekar, Minister for Environment, Forests and Climate Change of  India , recalled the global democratic effort to take climate action in a nationally determined manner, based on the principle of common but differentiated responsibility and respective capabilities.  He cautioned the Council against building a parallel climate track where such principles are “brushed aside”.  Noting that there is no common, widely accepted methodology for assessing the links between climate change, conflict and fragility, he said fragility and climate impact are highly context‑specific.  In fragile contexts, where Governments struggle to provide basic services, emergency conditions are largely driven by political violence disrupting harvests and aid supplies, rather than by climate factors alone.  “A complete picture of climate vulnerability only emerges with an assessment of the State’s capacity to be the primary responder to interrelated environmental, social, economic and security dynamics,” he said.  While climate change does not directly cause violent conflict, its interaction with other social, political and economic factors can exacerbate conflict drivers.  He called for the building of robust governance structures at local, national and regional levels to address climate‑ and fragility-related risks, pressing donor countries to provide greater financial, technological and capacity-building assistance to help fragile States enact adaption and mitigation strategies.

John F. Kerry, Special Presidential Envoy for Climate of the United States , thanked European and other countries for their leadership on climate change during what he described as the United States “inexcusable absence” from the debate over the past four years.  Though climate change is indeed an existential threat, the world has yet to adequately respond to it.  Noting that the question of climate change is no longer one for debate, he declared:  “The evidence, the science, is screaming at us.”  Many of the world’s regions most impacted by climate change are also projected to become future conflict hotspots.  Therefore, the issue must feature in all of the Council’s work and reporting.  Emphasizing that President Joseph R. Biden understands that “we do not have a moment to waste”, he cited his new coordinated, whole-of-Government approach which aims to elevate the issue and put the United States on the path to sustainability that can never be reversed by any future President or demagogue.

Addressing climate change will require every country to step up and boost their level of ambition, he said, noting that the world’s largest carbon emitters bear the greatest responsibility.  First and foremost will be the need to reduce the use of coal globally.  “Inaction comes with a far higher price tag than action,” he said, stressing that, not since the industrial revolution has there been such potential to build back better in every part of the globe.  Just by doing nothing, humanity will march forward in what is tantamount to a mutual suicide pact, he warned, spotlighting the importance of the climate summit to be hosted by President Biden in the coming weeks, as well as the Conference of Parties to the UNFCCC to be held in Glasgow later in 2021.  The United States will also work with like-minded countries in the Council, he said, urging Member States to begin treating climate change as the security crisis that it is.

Xie Zhenhua, Special Envoy for Climate Change of China , said that, even as global climate governance enters a new and crucial phase, the spread of COVID-19 poses serious threats to the global response.  Given the differences in historical responsibility and development levels between States, he underscored the principle of common but differentiated responsibility and urged developed nations to lead the way.  In building back after the pandemic, countries should respect nature, protect biodiversity, champion green lifestyles and “avoid old paths of giving without taking” from the Earth.  In that context, he described climate change as a development issue, urging the international community to support developing nations, least developed countries and small island developing States in implementing mitigation and adaptation measures.

“We need to stay committed to multilateralism,” he stressed, underlining the importance of UNFCCC and the Paris Agreement as the main channels for those critical discussions.  Any role to be played by the Security Council on climate change must fall under its purview, he added.  Outlining China’s commitment to fulfilling its responsibilities under the Paris Agreement, he spotlighted its recently announced plan to have national CO 2 emissions peak before 2030 and to achieve carbon neutrality prior to 2060.  He also pointed out that the country’s forest cover has been rising steadily for many years, that it leads the world in green power generation and that it tops the list of clean energy patents registered.

The representative of the Russian Federation agreed that addressing climate change requires a global approach that is coordinated, targeted at reducing emissions and implementing effective adaptation measures, especially through UNFCCC.  Noting that the Council has discussed climate change on several occasions, he said the issue is often presented as a fundamental threat to stability and as a root cause of problems, particularly in Africa, with warnings about the increasing risks of conflict.  While he agreed that climate change can exacerbate conflict, he questioned whether it is the root cause of violence.  “There are serious doubts,” he said.  The connection between climate and conflict can be examined only in certain countries and regions.  Discussing it in the global context is not relevant.  “Not all conflicts are threats to international peace and security,” he explained.  In addition, considering climate as a root cause of security issues distracts from the true root causes, and thus, hinders solutions.  Political and socioeconomic factors, which have a greater influence on conflict risk, cannot be ignored, he said, pointing out that COVID-19 has exacerbated inequalities within and between countries and sparked an uptick in hunger — including in countries that were already in conflict.  He urged donors to address the problem of “green protectionism”, seen in their refusal to exchange technology that would allow others to adapt.   While discussing climate issues in the Council is seen as beneficial, the “real work” of improving coordination of international activities would be better accomplished in the General Assembly, the Economic and Social Council and UNFCC.  Conflicts — in and of themselves — reduce the ability of States to adapt to climate change, he said, explaining that the increased security risks in the Sahel are, in fact, caused by countries pursuing regime change in Libya.

Lazarus McCarthy Chakwera, President of Malawi , speaking for the least developed countries, said building resilience to mitigate the security risks associated with climate change must begin with reflections on COVID-19, as Governments have relegated many other priorities in the quest to fight the virus.  Describing the impact of the nexus between climate change and security is “indiscriminate and consequential”, he said water scarcity, desertification and cyclones all foster competition for resources, and in the process, turn people into climate refugees.  Least developed countries bear the brunt of these phenomena, despite that their emissions are 30 times lower than those of high‑income countries.  Stressing that recovery from the coronavirus must be aligned with efforts to limit global temperature rise to 1.5°C, he pressed developed countries to approach the 2021 UNFCC meeting with more ambition than in years past, as their current commitments to cut emissions remain “woefully inadequate”.  They must fulfil their pledges to provide $100 billion in climate financing annually, answer the call to earmark 50 per cent of financing in the Green Climate Fund for adaptation, especially in least developed countries, and to meaningfully transfer climate‑friendly technologies to help least developed countries accelerate their green development efforts.

Gaston Alphonso Browne, Prime Minister and Minister for Finance and Corporate Governance of Antigua and Barbuda , spoke on behalf of the Alliance of Small Island States, declaring:  “Make no mistake […] climate change’s existential threat to our own survival is not a future consideration, but a current reality.”  For the past 30 years, the Alliance has been the single most consistent advocate on climate, he said, highlighting the often-overlooked threats faced by small island developing States.  He urged the international community to simultaneously plan and operationalize a system to address inevitable loss and damage which uproot peace and security of small island developing States.  Equitable solutions are needed to systematically address difficult issues, such as climate change displacement, including the treatment of climate refugees, and loss of territory. For the past three decades, small island and low-lying States have been sounding the alarm, sending the SOS distress signal.  They are losing their territories, populations, resources and very existence due to climate change.  The Secretary-General recently stated:  “Without nature’s help, we will not thrive or even survive[…] For too long, we have been waging a senseless and suicidal war on nature.”  Sadly, small island developing States continue to be the front line for this war.  “Our appeal for the Council is to take this threat very seriously before it is too late,” he said.

Heiko Maas, Federal Minister for Foreign Affairs of Germany , speaking for the Group of Friends of Climate and Security, said those countries are united by the common belief that climate change is the fundamental challenge of our time.  The poorest and most vulnerable are suffering the most, with entire islands at risk of disappearing.  “We are putting their future, their safety and their well‑being at risk if we don’t act,” he stressed, calling for concerted efforts by the United Nations in making climate change its top priority.  Agreeing with other speakers that the issue has major implications for peace and security, he said it therefore belongs firmly on the Council’s agenda.  In July 2020, the Nauru delegation presented the organ with a plan of action, including calling for the appointment of a Special Envoy on Climate and Security; regular reporting to the Council; climate‑sensitive peacebuilding; and more cooperation with civil society, regional and national actors on climate-related security risks.  Now, it is time for the Council to adopt a strong resolution reflecting each of those points, he said.
