Is America Ready for ‘Degrowth Communism’?

News Feed
Tuesday, May 28, 2024

Kohei Saito knows he sounds like a madman. That’s kind of the point, the Japanese philosopher told me during a recent visit to New York City. “Maybe, then, people get shocked,” he said. “What’s this crazy guy saying?”The crazy idea is “degrowth communism,” a combination of two concepts that are contentious on their own. Degrowth holds that there will always be a correlation between economic output and carbon emissions, so the best way to fight climate change is for wealthy nations to cut back on consumption and reduce the “material throughput” that creates demand for energy and drives GDP.The degrowth movement has swelled in recent years, particularly in Europe and in academic circles. The theory has dramatic implications. Instead of finding carbon-neutral ways to power our luxurious modern lifestyles, degrowth would require us to surrender some material comforts. One leading proponent suggests imposing a hard cap on total national energy use, which would ratchet down every year. Energy-intensive activities might be banned outright or taxed to near oblivion. (Say goodbye, perhaps, to hamburgers, SUVs, and your annual cross-country flight home for the holidays.) You’d probably be prohibited from setting the thermostat too cold in summer or too warm in winter. To keep frivolous spending down, the government might decide which products are “wasteful” and ban advertising for them. Slower growth would require less labor, so the government would shorten the workweek and guarantee a job for every person.Saito did not invent degrowth, but he has put his own spin on it by adding the C word.As for what kind of “communism” we’re talking about, Saito tends to emphasize workers’ cooperatives and generous social-welfare policies rather than top-down Leninist state control of the economy. He says he wants democratic change rather than revolution—though he’s fuzzy on how exactly you get people to vote for shrinkage.This message has found an enthusiastic audience. Saito’s 2020 book, Capital in the Anthropocene, sold half a million copies. He took a job at the prestigious University of Tokyo and became a regulator commentator on Japanese TV—one of the few far-left talking heads in that country’s conservative media sphere. When we met up in April, he was touring the northeastern U.S. to promote the new English translation of the book, titled Slow Down: The Degrowth Manifesto, and planning to appear on a series of panels at Georgetown University to discuss his ideas. One day during his New York stint, we visited the pro-Palestinian protests at Columbia University, where a young protester named Tianle Zhang spotted him and waved him over, telling Saito he’s the reason he’s applying to graduate school. They took a selfie together and Saito posted it on X.Saito’s haters are just as passionate as his admirers. The right-wing podcaster James Lindsay recently dedicated a three-hour episode to what he called Saito’s “death cult.” Liberals who favor renewable energy and other technologies say Saito’s ideas would lead to stagnation. On the pro-labor left, Jacobin magazine published multiple pieces criticizing degrowth in general and Saito in particular, calling his vision a “political disaster” that would hurt the working class. And don’t get the Marxist textualists started; they accuse Saito of distorting the great man’s words in order to portray Marx as the OG degrowth communist.It’s understandable why Saito provokes so much ire: He rejects the mainstream political consensus that the best way to fight climate change is through innovation, which requires growth. But no matter how many times opponents swat it down, the idea of degrowth refuses to die. Perhaps it survives these detailed, technical refutations because its very implausibility is central to its appeal.Economic growth, the French economist Daniel Cohen has written, is the religion of the modern world. Growth is the closest thing to an unalloyed good as exists in politics or economics. It’s good for the rich, and it’s good for the poor. It’s good if you believe inequality is too high, and if you think inequality doesn’t matter. Deciding how to distribute wealth is complicated, but in theory it gets easier when there’s more wealth to distribute. Growth is the source of legitimacy for governments across the political spectrum: Keep us in power, and we’ll make your life better.Japan has worshipped as devoutly as anyone. After the country’s defeat in World War II, GDP replaced military might as a source of national pride. Japan’s economy grew at a rate of nearly 10 percent until the 1970s and remained strong through the 1980s as its automotive and electronics industries boomed. So when the Asian financial bubble burst and the Japanese economy collapsed in the early 1990s, the country faced not just an economic crisis, but a crisis of meaning. If Japan wasn’t growing, what was it?[Read: Does the economy really need to stop growing quite so much?]Saito was born in 1987, just before the crash, and he grew up in a time of stagnation. As a student at a private all-boys secondary school, his politics were moderate, he says. He thought of problems like inequality and consumerism in terms of individual moral failings rather than as the consequences of policy choices. But the war in Iraq got him reading Noam Chomsky, college introduced him to Marx, and the 2008 financial crisis spurred him to question the capitalist system. Saito briefly enrolled at the University of Tokyo, but transferred to Wesleyan University, which he found insufficiently radical, on a scholarship. He graduated in 2009.The 2011 earthquake and nuclear disaster at Fukushima pushed Saito to reconsider humanity’s relationship with nature. “Fukushima caused me to question whether technology and the increase of productive forces create a better society,” he said. “The answer was no.”Saito moved to Berlin and got his Ph.D. at Humboldt University, where he studied Marx’s views on ecology. In 2016, he published an academic treatise on Marx’s “ecosocialism,” the English translation of which won the prestigious Deutscher Memorial Prize for books in the Marxist tradition.Around that time, the idea of degrowth, which had been kicking around environmentalist circles for decades, was gaining steam in Europe. Saito started reading thinkers such as Tim Jackson, Giorgos Kallis, and Kate Raworth, all of whom argued that there are planetary boundaries we can’t exceed without causing mayhem. Thinkers since Thomas Malthus had been talking about limits to humanity’s expansion—sometimes with disturbing implications, as in Paul Ehrlich’s 1968 best seller, The Population Bomb, which described with disgust a teeming Delhi slum. But degrowthers identified the pursuit of GDP as the culprit, arguing that it fails to account for all kinds of human flourishing. Greta Thunberg amplified the degrowth message further when she mocked capitalist society’s “fairy tales of eternal economic growth.”Japan was a ripe target for these ideas. For decades, the country had been mired in low and sometimes even negative growth. The problem was no longer new, and the government’s proposed solutions—negative interest rates; trying to boost worker productivity—were losing their appeal. “A lot of young people feel like, I don’t want to work endless overtime and give up my family life and all my hobbies just to serve a corporation until I die,” says Nick Kapur, an associate professor at Rutgers University at Camden who studies modern Japanese history. “For what? Just to grow our GDP?”  Saito saw an opening: to connect degrowth with the Marxist ideas that he had been studying closely for years. Degrowth on its own had bad branding, he told me between bites of Beyond Burger at Tom’s Restaurant in Morningside Heights. The solution, he said with a grin, was to add “another very negative term: communism.”When we met, Saito had traded his usual blazer and clean-cut look for an oversize denim jacket and a boy-band tousle. He has a disarming sense of humor: When he signs a book, he stamps it with a cartoon image of himself alongside Marx. But he’s serious about the need to embrace degrowth communism. He argues, not unreasonably, that degrowth is incompatible with capitalism, which encourages individuals to act selfishly and grow their riches. “Many people criticize neoliberalism,” Saito said. “But they don’t criticize capitalism. So that’s why we have ethical capitalism, sustainable capitalism, green capitalism.” Degrowth communism instead targets what Saito says is the root cause of our climate woes—capitalism itself—rather than just the symptoms, and prioritizes the public good over profit.While degrowthers and Marxists have plenty of intellectual overlap, the match has always been an awkward one. Marx is generally considered pro-growth: He wanted to leverage the productive tools of capitalism to bring about a socialist future in which the fruits of that production would be fairly distributed. Saito, however, rejects that “Promethean” characterization of Marx. In Capital in the Anthropocene, he instead argues that Marx converted late in life from productivism to, yes, degrowth communism. To make his case, Saito cites some of Marx’s lesser-known writings, including a draft of his 1881 letter to the Russian revolutionary writer Vera Zasulich and Critique of the Gotha Programme, which was published after Marx’s death.Saito’s book is a mishmash of political polemic, cultural criticism, and obscure Marxist exegesis. He calls individual actions like using a thermos instead of plastic water bottles “meaningless,” and mocks the UN Sustainable Development Goals, dismissing them and other market-friendly solutions as “the opiate of the masses.” Instead of relying on technology alone to save humanity, he argues, wealthy countries need to give up their consumerist lifestyles and redistribute their resources to poor countries to help them navigate the transition to a slower global economy. He advocates transitioning away from capitalism toward a “sharing economy,” and offers a mix of solutions both modest and bold. Workers should own their businesses. Citizens should control local energy production. Also: “What if Uber were publicly owned, turning its platform into a commons?” Saito argues that this arrangement would produce not scarcity but “radical abundance” as we freed ourselves from the obligation to generate ever-higher profits: “There will be more opportunities to do sports, go hiking, take up gardening, and get back in touch with nature. We will have time once again to play guitar, paint pictures, read … Compared to cramming ourselves into crowded subways every morning and eating our deli lunches in front of our computers as we work nonstop for hours and hours every day, this is clearly a richer lifestyle.”On a superficial level, Saito put a fresh young face on old environmentalist ideas. Well spoken and self-deprecating, he didn’t have the off-putting self-seriousness of many ideologues. After years of ineffective stimulus and grind culture, Saito’s ideas may have intrigued Japanese audiences looking for “the opposite of the status quo,” Nick Kapur told me. Saito’s analysis also offered a kind of tonic for Japan’s national neurosis around slow growth: What if this is good, actually? On a recent Saturday, Saito sat onstage at the People’s Forum, a community center in New York’s Chelsea neighborhood, along with three other panelists: a historian, a geographer, and a journalist from The New Republic. It was a friendly crowd, but each of the panelists cast gentle doubt on Saito’s pitch. The historian said he’d like to see more modeling of the impact of degrowth policies; the geographer wondered how a degrowth agenda would ever expand beyond small, local experiments; and the journalist, Kate Aronoff, suggested that degrowth had a branding problem.Saito had just begun his U.S. tour, and he was already encountering more resistance than he’d expected. “One thing surprising about American culture is they’re really anti-degrowth,” Saito told me after the event, as we walked along a chaotic stretch of 9th Avenue. When an American writer recently laced into him online, Saito’s European friends came to his defense. But here he was more isolated.The simplest case against degrowth is that it’s not necessary. The prospect of boosting GDP while reducing emissions—known as “decoupling”—used to look like a moon shot. But now it’s happening. In more than 30 countries, including the United States and much of Europe, emissions are declining while GDP climbs, even when you factor in the “consumption-based emissions” generated in places that manufacture goods for rich countries. Solar and wind are cheaper in the U.S. than fossil fuels. Electric vehicles, for all their struggles, will make up half of global car sales by 2035, according to one recent estimate. Decoupling still isn’t happening nearly fast enough to meet the goals of the Paris Agreement, but green-growthers argue that we can speed up the process with enough investment. “It’s easy to say we need a socialist revolution to solve the climate crisis, but that’s not going to happen in the timescale,” says Robert Pollin, a progressive economist at the University of Massachusetts at Amherst who co-authored a book with Noam Chomsky on the Green New Deal.Other detractors say that degrowth would be actively harmful. It’s one thing to ask billionaires to cut back, but what about everyone else? Are they supposed to abandon hope of raising their standard of living? Saito includes working-class Americans in his indictment of the “imperial mode of living” that he blames for carbon emissions. This was too much for Matt Huber, a professor of geography at Syracuse University, and the left-leaning climate journalist Leigh Phillips, who co-wrote an article for Jacobin accusing Saito of doing “capital’s work” by “dividing the international working class against itself.”Perhaps the most vicious reads of Saito target his interpretation of Marx. In the eyes of his critics, his reliance on a handful of passages in order to prove that Marx embraced degrowth communism amounts to a kind of fan fiction. One otherwise-sympathetic scholar wrote in a Marxist journal that the evidence Saito marshals is “simply not very convincing.” Huber and Leigh describe various claims about Marx’s views made by Saito as “wild,” “remarkable,” and “unsubstantiated.” Even John Bellamy Foster, the University of Oregon sociology professor who pioneered Marxist ecological studies in the 1990s and published Saito’s first book, told an interviewer that “no concrete evidence could be found of Marx actually advocating what could reasonably be called degrowth” and called Saito’s analysis “profoundly ahistorical.” (Saito responded in an email that Huber and Phillips “never read Marx’s notebooks that I investigate. Thus, they are not in a position to judge whether my claims are unsubstantiated because I am rereading Marx’s texts based on new materials.” As for Foster’s criticism, Saito wrote: “​​Marx never used the terms like degrowth, sustainability, and ecology. It is an attempt to push beyond Marx’s thought because there is no necessity to dogmatize Marx and he did not complete his work.”)The question of whether Marx was a degrowther is academic—and so is degrowth itself, unless it can find a viable political path. Right now, that path is murky at best. The next politician to win reelection by urging voters to accept a lower standard of living will be the first. In the U.S., policies like a carbon tax and a national cap-and-trade program are dead on arrival. Even in Europe, farmers are protesting environmental regulations that they say erode their livelihoods. In today’s politics, proposing sacrifice seems like an obvious form of political suicide that would only empower politicians who don’t care about climate change.Saito nonetheless insists that degrowth is politically possible. It starts small, he says, with workers’ cooperatives and citizens’ assemblies, and then spreads from city to city. Europe is already taking the lead, he says: Amsterdam recently banned building new hotels, while Paris restricted parking for SUVs. (One could fairly ask whether these are degrowth policies or just traditional forms of regulation.) The Spanish government has piloted a four-day workweek, Barcelona has introduced car-free “superblocks,” and the Spanish city of Girona has begun to explore how to implement “post-growth policies.” Saito says success is simply a matter of convincing a critical mass of citizens to push for degrowth. He cites the statistic popularized by the Harvard political scientist Erica Chenoweth that it only takes 3.5 percent of the population protesting to enact change.Isn’t expecting rich countries to act against their own interests a little optimistic? “Oh, yeah,” Saito said. “But the capitalist alternative is much more optimistic.” For Saito, the long-term alternative to degrowth communism is not green growth but “climate fascism,” in which countries lock down, hoard their resources, and disregard the collective good. Faced with that prospect, humanity will make the right choice. “As a philosopher,” he said, “I want to believe in the universality of reason.”Saito does propose a few concrete fixes: Ban private jets. Get rid of advertising for harmful goods and services, such as cosmetic surgery. Enact a four-day workweek. Encourage people to own one car, instead of two or three. Require shopping malls to close on Sundays, to cut down on the time available for excessive consumption. “These things won’t necessarily dismantle capitalism,” he said. “But it’s something we can do over the long term to transform our values and culture.”Of course, transforming values might be the heaviest lift of all. “Changing people’s preferences is really hard,” Dietrich Vollrath, an economist at the University of Houston who studies growth, told me. “You don’t need to change people’s preferences if you just make solar really cheap.” The Harvard economist Benjamin Friedman, who wrote The Moral Consequences of Economic Growth, says people fundamentally care about raising their material living standards and always will. “Trying to reform humanity is not a project of much interest to economists,” he told me. “We talk about what to do, not how to wish for another form of human being.”Saito admits that he might be overshooting. He isn’t expecting countries to scale down in the next decade, but maybe after that. He’s not opposed to green-energy subsidies; he just wants degrowth to be part of the conversation. He emphasized that his ideas aren’t designed with realism in mind. “I’m not an activist,” he said. “I’m a scholar.” His job is to provide the theory behind the change. Making it work is up to others.Degrowthers like Saito seem to be caught in a double dilemma. They bristle at the suggestion that degrowth would take us back to premodern standards of living—yet in trying to dispel that notion, they narrow their vision so far that it resembles business-as-usual left-of-center politics. A typical rundown of degrowth policies looks like a wish list from the Democratic Socialists of America: health care for all, universal basic income, a smaller military, mutual aid, better public transportation, decolonization, and so on. Adherents reject the view that degrowth would require some authoritarian power to impose it, but have yet to articulate a political plan besides changing one mind at a time.“At bottom it’s not actually an evidence-based agenda,” Ted Nordhaus, the founder and executive director of the Breakthrough Institute and self-described “eco-modernist,” told me. “It’s sort of a worldview and a vibe.”And yet, for many, the vibe hits. Degrowth captures a core truth of the fight against climate change: What we’re doing is not enough and might even be making things worse. Degrowth might fail too, but in the eyes of its supporters, at least it’s directionally correct. It’s the protest vote of climate activism.While in D.C., Saito co-headlined a workshop with a few dozen students at Georgetown, where they discussed degrowth. The group was mostly in favor, according to two students who attended. Fiona Naughton, a rising sophomore who studies international labor policy, told me she and many of her peers find Saito’s ideas inspiring. “A lot of us have felt such immense climate anxiety and considered whether or not we should have children,” she said. “Degrowth gives us hope for a future that we haven’t felt in a long, long time.”I also followed up with Tianle Zhang, the protester who’d taken a selfie with Saito at the Columbia rally, and asked him about how he’d discovered Saito’s work. Zhang said that as a kid in Indiana, he’d watched the news in horror as oil gushed into the Gulf of Mexico for months after the Deepwater Horizon rig exploded. In college, he’d sensed a gap between the immensity of the problem of climate change and the attempts to address it. Saito was one of the few scholars he found who was trying to connect thinking about the environment with a broader theoretical critique of capitalism and society.Zhang said he was also deeply influenced by Paul Schrader’s 2017 film, First Reformed. The film stars Ethan Hawke as a troubled priest who descends so far into climate despair that he considers committing an act of terrorism. “For me, it was showing the failures of conventional morality to handle the issue of climate,” Zhang said.[From the January/February 2023 issue: Why the age of American progress ended]Degrowth’s appeal might be similar: not political, not even economic, but moral. In the climactic final scene of First Reformed, Hawke’s character wraps himself in barbed wire as he prepares to possibly do something horrifying and futile. This seems like a fitting metaphor for not only Saito’s proposals—Saito acknowledges that degrowth would require pain—but also their psychological appeal. We have been bad, and we must atone.Beyond its stark moral claims, the very fact of degrowth’s unreasonableness gives it weight. Degrowth advocates have called it a “missile word,” designed to provoke. There’s a reason we’re talking about degrowth and not the “steady-state economy,” which environmentalists have been pushing for decades. As the prominent degrowth thinker Jason Hickel has written, the term itself upends conventional wisdom: “It is only negative if we start from the assumption that more growth is good and desirable.” To this way of thinking, the inconceivability of degrowth only highlights how trapped we are in the growth-fetishist mindset.At the end of our dinner, Saito told me he’s working on his next book, about the role of government when it comes to implementing degrowth. “The state has to intervene, but how can we make a democratic transition?” he asked rhetorically. I asked if he had an answer. He said, “Not yet.”

Kohei Saito’s theory of how to solve climate change is economically dubious and politically impossible. Why is it so popular?

Kohei Saito knows he sounds like a madman. That’s kind of the point, the Japanese philosopher told me during a recent visit to New York City. “Maybe, then, people get shocked,” he said. “What’s this crazy guy saying?

The crazy idea is “degrowth communism,” a combination of two concepts that are contentious on their own.

This was too much for Matt Huber, a professor of geography at Syracuse University, and the left-leaning climate journalist Leigh Phillips, who co-wrote an article for Jacobin accusing Saito of doing “capital’s work” by “dividing the international working class against itself.”

Perhaps the most vicious reads of Saito target his interpretation of Marx. In the eyes of his critics, his reliance on a handful of passages in order to prove that Marx embraced degrowth communism amounts to a kind of fan fiction. One otherwise-sympathetic scholar wrote in a Marxist journal that the evidence Saito marshals is “simply not very convincing.” Huber and Leigh describe various claims about Marx’s views made by Saito as “wild,” “remarkable,” and “unsubstantiated.” Even John Bellamy Foster, the University of Oregon sociology professor who pioneered Marxist ecological studies in the 1990s and published Saito’s first book, told an interviewer that “no concrete evidence could be found of Marx actually advocating what could reasonably be called degrowth” and called Saito’s analysis “profoundly ahistorical.” (Saito responded in an email that Huber and Phillips “never read Marx’s notebooks that I investigate. Thus, they are not in a position to judge whether my claims are unsubstantiated because I am rereading Marx’s texts based on new materials.” As for Foster’s criticism, Saito wrote: “​​Marx never used the terms like degrowth, sustainability, and ecology. It is an attempt to push beyond Marx’s thought because there is no necessity to dogmatize Marx and he did not complete his work.”)

The question of whether Marx was a degrowther is academic—and so is degrowth itself, unless it can find a viable political path. Right now, that path is murky at best. The next politician to win reelection by urging voters to accept a lower standard of living will be the first. In the U.S., policies like a carbon tax and a national cap-and-trade program are dead on arrival. Even in Europe, farmers are protesting environmental regulations that they say erode their livelihoods. In today’s politics, proposing sacrifice seems like an obvious form of political suicide that would only empower politicians who don’t care about climate change.

Saito nonetheless insists that degrowth is politically possible. It starts small, he says, with workers’ cooperatives and citizens’ assemblies, and then spreads from city to city. Europe is already taking the lead, he says: Amsterdam recently banned building new hotels, while Paris restricted parking for SUVs. (One could fairly ask whether these are degrowth policies or just traditional forms of regulation.) The Spanish government has piloted a four-day workweek, Barcelona has introduced car-free “superblocks,” and the Spanish city of Girona has begun to explore how to implement “post-growth policies.” Saito says success is simply a matter of convincing a critical mass of citizens to push for degrowth. He cites the statistic popularized by the Harvard political scientist Erica Chenoweth that it only takes 3.5 percent of the population protesting to enact change.

Isn’t expecting rich countries to act against their own interests a little optimistic? “Oh, yeah,” Saito said. “But the capitalist alternative is much more optimistic.” For Saito, the long-term alternative to degrowth communism is not green growth but “climate fascism,” in which countries lock down, hoard their resources, and disregard the collective good. Faced with that prospect, humanity will make the right choice. “As a philosopher,” he said, “I want to believe in the universality of reason.”

Saito does propose a few concrete fixes: Ban private jets. Get rid of advertising for harmful goods and services, such as cosmetic surgery. Enact a four-day workweek. Encourage people to own one car, instead of two or three. Require shopping malls to close on Sundays, to cut down on the time available for excessive consumption. “These things won’t necessarily dismantle capitalism,” he said. “But it’s something we can do over the long term to transform our values and culture.”

Of course, transforming values might be the heaviest lift of all. “Changing people’s preferences is really hard,” Dietrich Vollrath, an economist at the University of Houston who studies growth, told me. “You don’t need to change people’s preferences if you just make solar really cheap.” The Harvard economist Benjamin Friedman, who wrote The Moral Consequences of Economic Growth, says people fundamentally care about raising their material living standards and always will. “Trying to reform humanity is not a project of much interest to economists,” he told me. “We talk about what to do, not how to wish for another form of human being.”

Saito admits that he might be overshooting. He isn’t expecting countries to scale down in the next decade, but maybe after that. He’s not opposed to green-energy subsidies; he just wants degrowth to be part of the conversation. He emphasized that his ideas aren’t designed with realism in mind. “I’m not an activist,” he said. “I’m a scholar.” His job is to provide the theory behind the change. Making it work is up to others.

Degrowthers like Saito seem to be caught in a double dilemma. They bristle at the suggestion that degrowth would take us back to premodern standards of living—yet in trying to dispel that notion, they narrow their vision so far that it resembles business-as-usual left-of-center politics. A typical rundown of degrowth policies looks like a wish list from the Democratic Socialists of America: health care for all, universal basic income, a smaller military, mutual aid, better public transportation, decolonization, and so on. Adherents reject the view that degrowth would require some authoritarian power to impose it, but have yet to articulate a political plan besides changing one mind at a time.

“At bottom it’s not actually an evidence-based agenda,” Ted Nordhaus, the founder and executive director of the Breakthrough Institute and self-described “eco-modernist,” told me. “It’s sort of a worldview and a vibe.”

And yet, for many, the vibe hits. Degrowth captures a core truth of the fight against climate change: What we’re doing is not enough and might even be making things worse. Degrowth might fail too, but in the eyes of its supporters, at least it’s directionally correct. It’s the protest vote of climate activism.

While in D.C., Saito co-headlined a workshop with a few dozen students at Georgetown, where they discussed degrowth. The group was mostly in favor, according to two students who attended. Fiona Naughton, a rising sophomore who studies international labor policy, told me she and many of her peers find Saito’s ideas inspiring. “A lot of us have felt such immense climate anxiety and considered whether or not we should have children,” she said. “Degrowth gives us hope for a future that we haven’t felt in a long, long time.”

I also followed up with Tianle Zhang, the protester who’d taken a selfie with Saito at the Columbia rally, and asked him about how he’d discovered Saito’s work. Zhang said that as a kid in Indiana, he’d watched the news in horror as oil gushed into the Gulf of Mexico for months after the Deepwater Horizon rig exploded. In college, he’d sensed a gap between the immensity of the problem of climate change and the attempts to address it. Saito was one of the few scholars he found who was trying to connect thinking about the environment with a broader theoretical critique of capitalism and society.

Zhang said he was also deeply influenced by Paul Schrader’s 2017 film, First Reformed. The film stars Ethan Hawke as a troubled priest who descends so far into climate despair that he considers committing an act of terrorism. “For me, it was showing the failures of conventional morality to handle the issue of climate,” Zhang said.

[From the January/February 2023 issue: Why the age of American progress ended]

Degrowth’s appeal might be similar: not political, not even economic, but moral. In the climactic final scene of First Reformed, Hawke’s character wraps himself in barbed wire as he prepares to possibly do something horrifying and futile. This seems like a fitting metaphor for not only Saito’s proposals—Saito acknowledges that degrowth would require pain—but also their psychological appeal. We have been bad, and we must atone.

Beyond its stark moral claims, the very fact of degrowth’s unreasonableness gives it weight. Degrowth advocates have called it a “missile word,” designed to provoke. There’s a reason we’re talking about degrowth and not the “steady-state economy,” which environmentalists have been pushing for decades. As the prominent degrowth thinker Jason Hickel has written, the term itself upends conventional wisdom: “It is only negative if we start from the assumption that more growth is good and desirable.” To this way of thinking, the inconceivability of degrowth only highlights how trapped we are in the growth-fetishist mindset.

At the end of our dinner, Saito told me he’s working on his next book, about the role of government when it comes to implementing degrowth. “The state has to intervene, but how can we make a democratic transition?” he asked rhetorically. I asked if he had an answer. He said, “Not yet.”

Insects Are Disappearing Even From “Untouched” Landscapes, Study Warns

A recent investigation by the University of North Carolina at Chapel Hill has revealed that insect numbers are falling sharply, even in landscapes with little direct human disturbance. This trend raises serious concerns for the stability of ecosystems that rely on insects for essential functions. Keith Sockman, an associate professor of biology at UNC-Chapel Hill, monitored flying insect populations across 15 field seasons between 2004 and 2024 in a subalpine meadow in Colorado. The site provided 38 years of weather records and had experienced minimal human impact. His analysis showed an average annual reduction of 6.6% in insect abundance, which adds up to a 72.4% loss over two decades. The decline was strongly linked to rising summer temperatures. Ecological importance of insects “Insects have a unique, if inauspicious position in the biodiversity crisis due to the ecological services, such as nutrient cycling and pollination, they provide and to their vulnerability to environmental change,” Sockman said. “Insects are necessary for terrestrial and freshwater ecosystems to function.” Colorado meadow used for Keith Sockman’s 20 year study. Credit: Keith Sockman (UNC-Chapel Hill)These results help fill an important gap in global insect research. Although many studies on insect decline emphasize ecosystems heavily altered by humans, far fewer have looked at populations in largely untouched environments. This work shows that sharp declines can still happen in such areas, pointing to climate change as a likely driving factor. “Several recent studies report significant insect declines across a variety of human-altered ecosystems, particularly in North America and Europe,” Sockman said. “Most such studies report on ecosystems that have been directly impacted by humans or are surrounded by impacted areas, raising questions about insect declines and their drivers in more natural areas.” Mountain ecosystems at risk Sockman emphasizes the urgency of these results for biodiversity conservation: “Mountains are host to disproportionately high numbers of locally adapted endemic species, including insects. Thus, the status of mountains as biodiversity hotspots may be in jeopardy if the declines shown here reflect trends broadly.” This research highlights the need for more comprehensive monitoring of insect populations in a variety of landscapes and adds urgency to addressing climate change. By showing that even remote ecosystems are not immune, the study underscores the global scale of the biodiversity crisis.

US senators call on big oil to disclose lobbying that led Trump to axe key climate rule

Senate committee investigates suspected push that led administration to overturn EPA’s endangerment findingIn the wake of the Trump administration’s announcement that it will overturn the rule which underpins virtually all US climate regulations, a Senate committee has launched an investigation into a suspected lobbying push that led to the move.On Tuesday, the Senate environment and public works committee sent letters to two dozen corporations, including oil giants, thinktanks, law firms and trade associations. The missives request each company to turn over documents regarding the 2009 declaration, known as the endangerment finding, which the Environmental Protection Agency (EPA) said in July that it will unmake.

In the wake of the Trump administration’s announcement that it will overturn the rule which underpins virtually all US climate regulations, a Senate committee has launched an investigation into a suspected lobbying push that led to the move.On Tuesday, the Senate environment and public works committee sent letters to two dozen corporations, including oil giants, thinktanks, law firms and trade associations. The missives request each company to turn over documents regarding the 2009 declaration, known as the endangerment finding, which the Environmental Protection Agency (EPA) said in July that it will unmake.The finding enshrined that carbon dioxide and five other greenhouse gases harm the health of Americans.“Rescinding the endangerment finding at the behest of industry is irresponsible, legally dubious, and deeply out of step with the EPA’s core mission of protecting human health and the environment, and the American public deserves to understand your role in advancing EPA’s dangerous decision,” wrote Rhode Island senator Sheldon Whitehouse, the ranking member of the committee. “I am concerned about the role that fossil fuel companies, certain manufacturers, trade associations, polluter-backed groups, and others with much to benefit from the repeal of the endangerment finding – including your organization – played in drafting, preparing, promoting, and lobbying on the proposal.”Fossil fuel companies and their allies are threatened by the endangerment finding because it confirms in law that carbon dioxide, which their products produce, are dangerous, Whitehouse told the Guardian. It also gives the EPA the authority to regulate those emissions under the Clean Air Act.The letter, which asks for all relevant private communications between the day Trump was re-elected in November to the day the EPA announced plans to rescind the endangerment finding in July, was sent to oil giants Exxon, Chevron, Shell, and BP, as well as coal producers, a rail giant and two auto manufacturers, whose business plans rely on fossil fuels.“The only interests that benefit from undoing the endangerment finding are polluter interests, and specifically fossil fuel polluter interests,” Whitehouse said.It was also sent to trade associations and law firms representing big oil and auto companies. And it was sent to far-right, pro-fossil fuel thinktanks Competitive Enterprise Institute, New Civil Liberties Alliance, the Heartland Institute, America First Policy Institute, and the Heritage Foundation, each of which challenge the authority of federal agencies, and some of which have directly praised the proposed endangerment finding rollback.The Guardian has contacted each recipient for comment.Because Republicans control the Senate, Democrats on the environment and public works committee lack the power to subpoena the documents. But the Senate committee still expects the companies to comply with their request.The letter could send a signal to polluting sectors and rightwing firms that they are being watched, and could set the stage for continued investigation if Democrats win back a congressional chamber in next November’s midterm elections.Fossil fuel interests pushed back on the endangerment finding when it was first written, yet little is known about more recent advocacy to overturn it. Immediately following the EPA’s announcement of the rollback, the New York Times reported that groups have not “been clamoring in recent years for its reversal”. But Whitehouse believes that has changed since Trump was re-elected in November 2025.When Joe Biden was president and Democrats controlled at least one chamber of Congress, Whitehouse said “a request to rescind the endangerment finding would have just looked like useless, pointless, madness.“But now that they can actually do it in their desperation and with the mask of moderation pulled off, I think it’s very clear that they were directing this happen,” he said.Under Trump, former lobbyists and lawyers for polluting industries such as oil, gas and petrochemicals have entered leadership positions at the EPA.“The fossil fuel industry owns and controls the Trump administration on all matters that relate to their industry, and they have subservient Republicans controlling both the House and the Senate,” said Whitehouse. “The change in power has allowed a change in tactics and attitude.”Two environmental non-profits have sued the Trump administration for “secretly” convening a group of climate contrarians to bolster its effort to topple the endangerment finding.The EPA’s proposed undoing of the crucial legal conclusion comes as part of a larger war on the environment by the Trump administration, which has killed dozens of climate rules since re-entering the White House in January.“The motive is to help fossil fuels survive,” said Whitehouse.

How Climate Change Is Increasing Landslide Risk Worldwide

As warming temperatures bring more extreme rain to the mountains, debris flows are on the rise

The landslide behind my neighbor’s backyard doesn’t exist—not according to the New York State landslide map or Greene County’s hazard-mitigation plan or the federal inventory managed by the U.S. Geological Survey. But when you’re standing in the middle of the debris field, the violence of the event is still evident 14 years after it occurred. The fan of the landslide, where a surge of boulders and mud blasted the forest open after rushing down the steeper slopes of Arizona Mountain in the Catskills, is about 100 feet wide—an undulating plane of rocks, mangled tree trunks, and invasive plants such as Japanese stiltgrass that thrive in disturbed areas.On a hot July day the seasonal stream that runs through this ravine, named the Shingle Kill, is small enough to step over. When Tropical Storm Irene hovered over these mountains on August 28, 2011, the Shingle Kill swelled like all the otherwise unremarkable streams in the area, frothing downhill in a torrent the color of chocolate milk. This storm was a particularly bad one, dropping up to 18 inches of rain on the northeastern escarpment of the Catskills. Throughout the region explosive rivers eroded their banks, flooding towns and ripping away buildings.The first house the Shingle Kill passes as it emerges into our community belonged at the time to Diane and Ken Herchenroder, who had lived there for nearly three decades. In the past, when the Shingle Kill occasionally raged, they could hear rocks colliding in the streambed. But this time it was louder—and faster.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

First it took out a 32-foot-long footbridge that connected one side of the property to the other. Then trees started coming downriver, crashing into a culvert at the bottom of the yard. The culvert clogged, washing out the road. Water got diverted across their lawn on one side of the stream, and in the other direction it blew out the garage side door, then the front doors. (Their lawn tractor was found downstream days later.) Diane watched her row of beloved lilac bushes, probably more than 100 years old and 15 feet tall, get ripped from their roots. “They just floated away. And we thought, that’s going to be it,” she recalls. “Then we heard a rumble like a train barreling down the mountain.”Less than 2,000 feet above, in a hollow high on Arizona Mountain, oversaturated soils released themselves into the headwaters of the Shingle Kill, picking up speed and whatever materials the flow encountered as it carved downhill.As the slope flattened out, the landslide blew open the channel and spread out, depositing a wall of uprooted trees just upstream of the house. A slurry of rocks and mud continued flowing, plugging the Shingle Kill streambed all the way to the road, where it was stopped by the debris dam at the culvert.Robert Titus, a retired geology professor, and his wife, Johanna Titus, explored the slide about a month later for their Kaatskill Geologist column in a local newspaper. “We don’t use the words ‘awe,’ ‘awesome’ or ‘awed’ very often; we save them for when they are truly appropriate,” they wrote. “This was one of those times.” They described scenes that were evidence of boulders “floating on the moving muds,” as well as hundreds of “twisted and broken trees” that had been thrown high above the stream bank and were now stranded on top of the ravine. The Tituses recently told me it was unlike anything they had seen before or since.In July 2025, days of heavy rain triggered multiple mudslides and rockslides in New York State's Adirondacks, including this one on Mount Colden. It blocked access to hiking trails in a popular recreation spot in the High Peaks Wilderness area.To this day, the scar where the landslide began is unmissable from miles away.That this landslide didn’t get recorded is somewhat a quirk of disaster recovery. Debris from the slide itself wasn’t the singular cause of damage to any buildings or roads, so there was no financial fingerprint. The slide didn’t injure or kill anyone. Landslides aren’t mapped in the same way that the Federal Emergency Management Agency, for instance, tracks flood zones and inundation risk, and a rate of occurrence can’t be modeled like a flood. Because landslide insurance practically doesn’t exist in most of the country, no one needs the data to assess actuarial risk for homeowners. According to the New York Geological Survey, the vast majority of landslides in the state go unreported.But the Shingle Kill landslide did change the mountainside that day. Joel DuBois, director of the Greene County Department of Soil and Water, visited the site in the days after Irene and reviewed some recent photos of the stream corridor that was affected by the debris flow. “There appear to be a number of cycles of incision and aggradation,” DuBois wrote. “That is to say that channel incision, or down-cutting, results in steeper bank angles and higher bank heights, leaving the adjacent hillsides susceptible to landslide” both during and after flood events. The sediment then flows downstream and accumulates at existing debris dams, which tends to cause channels to migrate laterally, he explained. That too can trigger landslide activity.The area remains vulnerable at a time when landslide risk is expected to increase across much of the northeastern U.S.—as well as a lot of the world. That’s because climate change is causing concentrated bursts of rain that fall over a short period to occur more frequently. Such intense rainfall events are known to be the biggest trigger of landslides.It’s not quite right to say landslides aren’t common in the Catskills, because this superold plateau has been eroding for perhaps a few hundred million years. On a nongeological timescale, though, landslide susceptibility isn’t something many people think about in New York State, and the state geological survey can estimate only that between 100 and 400 occur every year.As warmer temperatures lead to more moisture in the air, climate change is quickly warping that math. In the Northeast, the heaviest rainstorms are now 60 percent heavier than they were in the 1950s, according to the Fifth National Climate Assessment. In a 2023 study, researchers at Dartmouth College found that extreme precipitation in the region will increase by 52 percent by the end of this century, mostly because of a higher number of such events each year. “Our landscape has pretty much been in equilibrium, for the most part, since the glaciers left,” Andrew Kozlowski, a New York State geologist, explained during a 2022 USGS presentation. “With climate change, we may be shifting that equilibrium and throwing all of this completely off balance, and there’s going to be a natural readjustment.”“Landslide” is the broad term for the movement of soils, rocks, and other debris down a slope. There are several different classifications for landslides. Some, like the Shingle Kill debris flow, move far too fast to be outrun. More than any other factor, they are set off by an intense storm. Others, such as rotational slides—backward-curving masses of material that can be hundreds of feet deep—are more sensitive to rainfall over the course of a season. They can move very slowly when a destabilized slope takes months to fail.Landslides can happen pretty much anywhere certain conditions exist but are most common in very steep mountain terrain where plenty of rain falls. In 2024 the U.S. Landslide Susceptibility Index was released and stated that 44 percent of the land in the U.S. could potentially experience landslide activity. Susceptibility is based partly on where landslides have occurred previously, and it wasn’t until the past decade that high-resolution lidar made it possible for states to survey vast swaths of land for evidence and clues. The extent to which states have done so is uneven.Benjamin DeJong, director of the Vermont Geological Survey, says you can think of landslide susceptibility as an inexact recipe. You’re going to need steeper slopes to achieve some kind of baseload that puts weight on the slope. Next, add loose, unconsolidated materials that can become saturated with water. If those saturated materials are overlying or underlying another kind of material that has very different permeability, meaning its ability to take in water, that contrast is a big factor.“By far the year that had the greatest total landslides that I’ve recorded was 2024. Last year was completely off the scale.” —David Petley University of HullThen you look at what’s on the base and on the top of the slope. If the base, or toe, is undercut—by a road, for instance, or a meandering stream—that’s going to make the slope more susceptible. Overloading the top, or head, of a slope with weight also drives it toward failure.The fourth ingredient is the loss of vegetation that helps to hold soils together. In California, for example, this loss happens on a regular cycle with wildfires. Vermont, DeJong says, went through an experiment in the 1800s where “the state tried to turn itself into Scotland by cutting down all the trees and bringing in sheep.” It was a bad idea that caused erosion and mass slope failure everywhere. The state gave up on that plan and allowed the forests to regrow. The last variable is how the slope handles stormwater. With more extreme precipitation events, it doesn’t take much mismanagement of a slope for the heavy weight of rain to concentrate in ways that cause the slope to fail.Geologist David Petley, who writes the Landslide Blog for the American Geophysical Union, has been maintaining a database of deadly landslides worldwide since 2004. He’s seen a clear long-term trend. “But by far—by far—the year that had the greatest total landslides that I’ve recorded was 2024,” he says. “Last year was completely off the scale.” Why? “The most simple hypothesis is that it was the year with the highest-ever global temperature. I do genuinely think it’s that simple.” There’s solid evidence that high atmospheric temperature, and possibly high sea-surface temperatures as well, drove high-precipitation events globally. “Last year I saw an extraordinary frequency of big storms that were triggering hundreds of thousands of landslides,” Petley says. They occurred at different locations all over the world.In the U.S., the remnants of Hurricane Helene, which came ashore in Florida in September 2024, dumped between 20 and 30 inches of water over the mountains of North Carolina. The storm ended up triggering more than 2,000 landslides across the Southeast. According to the USGS, in some cases several smaller mudslides converged into a single channel, burying entire communities in debris. The total number of people killed by landslides specifically, versus by flooding or a combination of the two, is hard to parse. But one storm-triggered mudslide in Craigtown, N.C., swept through a house, killing 11 members of the Craig family for whom the town is named. During the storm, four successive landslides in that valley wiped out the town.In the Appalachian Mountains of North Carolina, very old landslides might have been “brought back into activity” during Helene, Petley explains, reactivated by staggeringly intense rain. Scientists at World Weather Attribution pinned that extra intensity on climate change, reporting that it had made the storm’s rainfall throughout the Southeast about 10 percent heavier and the “unprecedented” rainfall totals over three days about 70 percent more likely than they would have been otherwise.In California, where dramatic debris flows have long been a concern, climate change is making matters worse in two ways. Bigger, more destructive wildfires wipe out more of the vegetation that was stabilizing the landscape. And then atmospheric rivers—a newer phenomenon consisting of long, narrow conveyer belts of moisture—arrive, bringing a series of intense rainfall events. Between December 2022 and January 2023 nine back-to-back atmospheric rivers struck California, leading to more than 600 landslides.Climate change is increasing landslide risk globally in other ways. In high mountain regions such as the European Alps and the Himalayas, melting permafrost and retreating glaciers are destabilizing steep slopes. A catastrophic glacier collapse in Switzerland this past summer destroyed an entire village; thankfully officials evacuated people just before it happened, but one person was killed.A section of the Shingle Kill streambed 14 years after a debris flow occurred on Arizona Mountain in New York State's Catskills during intense rain. The southern slope, shown on the left, continues to erode.Petley says the thing that’s surprised him most recently is the speed of change, especially during this past El Niño cycle. Strong rainfall events have always happened occasionally, but suddenly they are happening a lot. “I don’t think I fully understand why we’re seeing such a rapid shift to these events where a heavy rainfall will trigger 2,000 or 3,000 landslides in a relatively small area,” Petley says. In New Zealand in 2023, Cyclone Gabrielle triggered at least 100,000 landslides. Even in regions such as the Himalayas, where the monsoon season is becoming drier overall, the number of landslides is going up because the rainstorms that do arrive are more intense. “I worry a bit,” Petley says, “that the shift is happening so fast and becoming so extreme that in some places the risk is essentially unmanageable.”Vermont, like New York State, got clobbered by Tropical Storm Irene in 2011. DeJong, the Vermont state geologist, describes Irene as a wake-up call. “The mountains,” he says with a degree of irony, “are now where hurricanes come to die.”But it wasn’t until two freak July rainstorms—spaced exactly a year apart, one in 2023 and one in 2024—that the state’s geological survey became alarmed that landslides were going to be a much bigger problem than in the past. Given his experiences with Irene, DeJong expected the July 2023 storm to lead to maybe a handful of slides. Within a month of the storm his team had received more than 70 requests for landslide evaluations. Working on the ground in the aftermath of these two storms made DeJong realize that rainfall events at that scale “are fundamentally altering the landscape in ways that are not immediately recognizable,” he says.Now the four-person Vermont Geological Survey team is working on putting together a landslide-susceptibility map. The goal is to start with a more technical tool for scientists that can be overlaid with forecasts from the National Weather Service, which would create debris-flow forecasts like the ones already produced by the Los Angeles Department of Public Works. If that’s successful, the next step, DeJong says, would be creating a map that’s more accessible to the public, something that a person who’s looking to buy a parcel of land could reference to do some due diligence on landslide risk.But that gets tricky. The city of Juneau, Alaska, carried out a mapping project to evaluate levels of risk, with the aim of incorporating that risk into its land-use planning in 2024. The maps also would have highlighted concerns with existing buildings, though, meaning homeowners identified as living in high-risk areas might see their property values decline. Juneau’s susceptibility map was vehemently rejected by the community last year and was not adopted. In Vermont, as in many places, evidence of slope instability—and even past failures—hardly factors into development or the issuing of building permits.Rising landslide risk in mountainous places also creates a difficult tension about how to adapt to the effects of climate change. Recent disasters have made clear that mountain valleys in certain regions may not be great places to live. In Vermont “we’re losing a lot of housing in our flood corridors—which is a good thing,” DeJong says. “We’re getting people out of harm’s way.” But the state, like many others around the country, has a housing crunch with the need to build more. “When we’ve lost options down in the valleys, that puts a lot of building pressure up onto our slopes,” he explains. “And it’s really hard to make the argument not to do that.” Successfully adapting to one climate effect means running headlong into another.There are many climate-related problems to worry about in my Catskills community: the surging numbers of disease-carrying ticks, the choking out of native plants by invasive species, the hurricane-remnant floods, the decrease in winter snowfall that would replenish the aquifers, the summertime whiplash between deluge and drought. The Shingle Kill landslide wasn’t on my radar as a potential climate problem until a massive, ultraluxury resort and “branded residences” development was proposed for the hillside next to it. The plan calls for building more than 85 new structures totaling 275,593 square feet on a 102-acre site, 45 percent of which is classified as having steep slopes. To do so, developers will have to cut down about 11 acres of trees. The site, like the rest of our hamlet, has no access to municipal water or sewage. In addition to lining ponds for water storage and building a wastewater-treatment plant, a road network will be cut into the mountainside.The public documents for the project do not appear to show that a geologist evaluated whether the weight of all that development, plus the deforestation and excavation during construction, might further destabilize the slopes of the Shingle Kill. Our town planning board approved the project in May 2025 without requiring an environmental impact statement that would have identified and attempted to mitigate the biggest hazards. (I am a member of a community group that is suing our town planning board, arguing it didn’t take a hard look at potentially significant adverse effects to the environment from this project, including on groundwater availability, erosion, flooding and landslide risk.)Recent intense rain events “are fundamentally altering the landscape in ways that are not immediately recognizable.” —Benjamin DeJong Vermont Geological SurveyDiane and Ken Herchenroder’s house wasn’t damaged by the 2011 landslide, but the event did plenty of harm. Much of their property was rearranged by the acute displacement of raging water. The solid plug of rocks and mud, some 10 feet tall, had to be excavated from the streambed. Even once things were fixed, they didn’t want to stay. “We used to listen to the rain and the stream with the windows open, and it was very comforting,” Diane says from their house in New Hampshire, where they moved two years after the storm. “Honestly, after that slide occurred, Ken and I, I would have to say, have a little bit of post-traumatic stress from that.” Diane says her photographs of the landslide are on a CD somewhere; she hasn’t looked at them since. “I don’t really ever even talk about that day,” she says. “It was pretty devastating.”In 2018 Joe Merlino bought the Herchenroders’ former property, where he now lives with his daughter and his mother. A few years ago they had members of the U.S. Army Corps of Engineers come assess ongoing erosion along the Shingle Kill. The streambed continues to widen, and a sharp curve just upstream of Merlino’s house means floodwaters could rush right at it. He recalls that in 2021, when Tropical Storm Henri came through the Catskills, boulders smashed against the bridge that provides access between his house and his mom’s trailer. “[The Army Corps] basically told us the erosion is not going to stop,” Merlino says.Merlino often walks along the edges of the fan with his dog, observing the changes to the old debris piles with each storm. The possibility of more landslide activity is never far from his mind, he says, especially with a major development approved for the hillside above his home.I asked him whether he gets scared every time there’s heavy rain. “I come home from work early,” he says, to keep an eye on things and intervene if necessary. A few years ago he moved his daughter’s bedroom to the front of the house, away from the steep pitch of his backyard. “My fear is about my living room, which is in the back and has a lot of glass,” he says. “I watch the water rip around that curve, and one day something is going to come through and take the side of my house right out.”Greene County, where the Merlino family and I both live, is one of the four counties identified by New York State as the most vulnerable to expected annual building loss from landslides in the future. The county has steep escarpments that slope into the Hudson River Valley, which is rich in clays and silts from Glacial Lake Albany, a prehistoric waterbody that drained some 10,500 years ago. “I think we’re going to see a lot more slope failures in some of these populated areas in the Hudson Valley,” Kozlowski, the New York State geologist, said in 2022.Greene County considered landslides a threat back in 2016. In 2023 the county revisited its hazard-mitigation plan; our town, Cairo, was the only municipality out of 19 that did not participate. In the updated plan, the county removed landslides as a hazard, reasoning that they are “unlikely to lead to a disaster.”It’s true that landslides don’t do the same economic harm to our county as flooding and ice storms. But when they do occur, rebuilding is rarely an option. When a family lost their house in the town of Catskill to a landslide after a heavy rain event in May 2024, there wasn’t much anyone could do but condemn the structure.With funding for emergency response and climate resilience endangered at the federal level, is it worth investing in susceptibility maps for landslides that may never occur? Should people hesitate to build on potentially unstable slopes when that’s perhaps less risky than living directly in a flood path?DeJong says these are valid questions, but after his experiences over the past few years, he sees things differently. “We in Vermont have, so far, been incredibly fortunate to not see any fatalities,” he says. He remembers an older couple who were sitting in their house in July 2023 when the slope behind it failed. The structure warped outward, bending absurdly into something “that looked like a fun house falling over on them,” he recalls. Emergency services extracted them relatively unharmed, but DeJong knows it could have been worse. It turned out a lot worse in western North Carolina during Helene, where for years many building codes dismissed the risk of construction on steep slopes.It might take only one bad slide to change people’s minds about the risk. Before 2014, DeJong says, Washington State, much like New England, did not pay much attention to landslides and had no landslide program in its state geological survey. But then a slope in Oso, about an hour outside Seattle, experienced a catastrophic failure, taking out a neighborhood and killing 43 people. The state now takes landslides very seriously.“The Oso slide of New England could be right around the corner,” DeJong says. “People will say, ‘Why didn’t we know about this hazard? X number of people just died.’” He hopes his team can get its landslide-susceptibility maps finished so that when big rainfall events are forecast for the Green Mountains, officials can warn people in especially risky areas. “We’re really trying to switch to being more proactive so that X never becomes a number.”

Bud Moses is all too aware of the longer, hotter summers impacting his community in Sydney’s west.As black summer bushfires raged on 4 January 2020, Penrith was sweltering in temperatures of 48.9C, making it the hottest place on the planet that day. It was just one of a growing number of above-40C days Moses has witnessed in recent years.“We’ve seen the heat get a lot worse – it’s one of the clear physical attributes of climate change that most people seem to understand,” Moses, the western Sydney organiser of the Nature Conservation Council of New South Wales, said.Landmark climate report shows 'every Australian has a lot at stake', minister says – video“People talk about what impacts them – and here, that’s heatwaves, flooding and bushfires,” he said of the locals he meets when running Tabiea, a joint Nature Conservation Council and Arab Council Australia climate change awareness campaign targeting western Sydney’s culturally diverse community.“It’s a lot for them to take physically and mentally.”It’s no surprise to him that Sydney’s west and south have emerged as “heat-health risk” hotspots in the federal government’s long-awaited national climate risk assessment. Sign up to get climate and environment editor Adam Morton’s Clear Air column as a free newsletterWarming across the Australian continent has already reached 1.5C, Monday’s report by the Australian Climate Service (ACS) noted. Under a 3C scenario, the number of heat-related deaths in Sydney increases by 444%.With heatwaves causing more deaths in Australia than all other extreme events combined, the report found Blacktown and the outer west are some of Sydney’s most exposed suburbs when considering the health risks associated with ever-hotter summers.Extreme heat may lead to higher rates of heat-related illness which in turn will put additional strain on emergency services and hospital infrastructure, according to the assessment.Moses said many in his community live in rented or social housing and do not have access to air conditioning – and those who do limit its use because of cost-of-living pressures. The area needed shaded bus stops, more green space and better environmental standards in rented homes, he said.“If you talk to doctors in relation to heat stress, all the forecasts are showing that it’s going to have an impact, especially on old and vulnerable people,” Moses said.A temperature rise of 3C would, he said, “be dire”.Dr Judith Landberg, head of the ACS, told a Senate committee on Tuesday the number of heat-related deaths in Sydney was currently between 80 and 117 annually.Heat-health risk index map of Sydney, provided by the Australian Climate ServiceThe Blacktown mayor, Brad Bunting, said the report confirmed the experiences of and research undertaken by his council.“Blacktown is on the frontline of extreme heat, and the national report shows how serious the risks are for our community,” he said in a statement.The council is part of the Western Sydney Regional Organisation of Councils, which developed the 2021 Heat Smart Western Sydney plan to prepare for and respond to heatwaves. The Blue Mountains, Liverpool, Cumberland and Hawkesbury councils are also members.“Urban heat is not just an environmental challenge. It affects health, liveability and how we plan our city,” Bunting said.Heat-health risk is lowered by urban greening, according to the report, with the leafy, generally affluent suburbs of the northern beaches, north Sydney and Hornsby found to have lower heat-health risk. The city’s eastern suburbs have a moderate heat-health risk.Dr Milton Speer, a meteorologist and fellow with the University Technology Sydney, said his research comparing weather observations from 1962 to 2021 between Observatory Hill on Sydney harbour and Richmond revealed the west was often 5C warmer.In the west, one in 10 days exceeded 35.4C. On the coast, one in 10 days was above 30.4C. One in 20 days reached 37.8C or more in the west.Speer said western Sydney was further from sea breezes which can regulate the heat – “and the fact that there are fewer trees is very important”.skip past newsletter promotionSign up to Clear Air AustraliaAdam Morton brings you incisive analysis about the politics and impact of the climate crisisPrivacy Notice: Newsletters may contain information about charities, online ads, and content funded by outside parties.

Darlinghurst is generally about 50 metres above sea level, while Kogarah’s elevation is about 30 metres.Aerial view of flooding at North Narrabeen, on Sydney’s northern beaches, in April. Photograph: AAPIt is understood the report’s analysis included areas within 10km of the coastline and that the effects of sea level rise were not constrained to the coastline.The Australian National University emeritus professor and chair of the assessment’s expert advisory committee, Mark Howden, said its authors had taken a conservative approach which did not reflect current expert assessments of future sea level rise.In a 3C scenario, the sea level would rise 54cm, according to the report.A separate research paper had put sea level rise at a median point of 111cm within a range of 62cm-238cm in a high emissions scenario, he said.Saltwater intrusions into freshwater suppliesThe City of Sydney lord mayor, Clover Moore, said her council, which covers some of the country’s most densely populated postcodes, was doing its “best to ensure the city remains climate-resilient and adapts to additional extreme heat, drought, storms, flash flooding and rising sea levels” – but that heat was its priority.“We are most concerned about the impact of hotter days, for longer periods,” she said in a statement.“We are currently in the process of updating our floodplain management plans to prepare the city for sea level rise, while also advocating for state government guidance to be updated to reflect recent climate modelling.”She said addressing sea level rise was a bigger issue than any one council could address alone and should be led by state and federal governments.The assessment suggests the effect of Sydney’s rising sea level may be more widespread, with saltwater intrusions threatening freshwater supplies and water security across the city.A spokesperson for the Georges River council, which covers Kogarah, said in a statement the council was “committed to the current and future resilience” of the LGA and was actively planning for a climate-resilient future.They said the council would “consider the insights” in the report.

Sweeping California climate bills heading to Newsom's desk

California state lawmakers gave their stamp of approval over the weekend to a slate of sweeping energy and climate-related bills, which will now head to Gov. Gavin Newsom’s (D) desk. The package's six bills — some of which passed with bipartisan support in an extended session on Saturday — marked a last-minute victory for Newsom, who negotiated the final terms of the legislation with State Senate and Assembly leaders over the past week. “We have agreed to historic reforms that will save money on your electric bills, stabilize gas supply, and slash toxic air pollution — all while fast-tracking California’s transition to a clean, green job-creating economy,” the governor said in a statement in the days leading up to the package’s passage. Within the package is a bill to increase the amount of climate credit appearing on utility bills, as well as another that would revive California’s ability to expand regional power markets via U.S. West clean energy. A third bill focused on improving utility wildfire safety by strengthening oversight and expanding a dedicated fund for wildfire readiness. The package also included an extension of the state’s cap-and-trade program, now to be known as “cap-and-invest.” This system, which sets emissions caps and distributes tradable credits within that framework, seeks to hold carbon polluters accountable by charging them for excessive emissions. Established by Republican Gov. Arnold Schwarzenegger in 2006, the program was set to expire in 2030 but would now be reauthorized until 2045, if signed into law. The fifth bill in the package centered on strengthening local air pollution reduction efforts and oversight by extending monitoring periods, redoubling the efforts of state and local air quality agencies to deploy effective strategies. A final piece of legislation, which received pushback from some progressive lawmakers, involved the stabilization of both in-state petroleum production and refinery supply, while also offering protections to communities located near wells. The Center for Biological Diversity slammed the passage of this bill, arguing that it was included “as a last minute ‘gut and amend’ measure at the end of the legislative session.” The bill, the organization warned, exempts oil drilling in California’s Kern County from state environmental quality requirements for the next decade, allowing for the approval of up to 20,000 new wells. “It’s senseless and horrifying that California just gave its seal of approval to this reckless ‘drill, baby, drill’ bill,” Hollin Kretzmann, an attorney for the center, said in a statement. Other environmental groups, however, voiced their support for the suite of climate-related bills, with the Natural Resources Defense Council (NRDC) commending the state for maintaining “its climate leadership.” NRDC staff members particularly praised the advancement of the cap-and-invest extension, as well as western grid regionalization and the wildfire protections. “While the Trump administration takes us backward, California will continue to address climate change, while improving affordability,” Victoria Rome, California government affairs director for the NRDC, said in a statement. “Our lives and prosperity depend on it.” In addition to the six-bill energy package, Newsom will also be receiving a selection of unrelated climate bills that received the legislature’s approval. Among those are first-in-the-nation legislation to require tests of prenatal vitamins for heavy metals, a public transportation funding bill and a plan to phase out toxic “forever chemicals” from cookware, food packaging and other consumer products.
