In War and Peace and War (2006), his most accessible book, he likens himself to Hari Seldon, the “maverick mathematician” of Isaac Asimov’s Foundation series, who can foretell the rise and fall of empires. In those 10,000 years’ worth of data, Turchin believes he has found iron laws that dictate the fates of human societies.

The fate of our own society, he says, is not going to be pretty, at least in the near term. “It’s too late,”

The problems are deep and structural—not the type that the tedious process of demo­cratic change can fix in time to forestall mayhem.

Turchin likens America to a huge ship headed directly for an iceberg: “If you have a discussion among the crew about which way to turn, you will not turn in time, and you hit the iceberg directly.” The past 10 years or so have been discussion. That sickening crunch you now hear—steel twisting, rivets popping—­­is the sound of the ship hitting the iceberg.

Of the three factors driving social violence, Turchin stresses most heavily “elite overproduction”—­the tendency of a society’s ruling classes to grow faster than the number of positions for their members to fill.

Don’t we want everyone to be rich and educated? The problems begin when money and Harvard degrees become like royal titles in Saudi Arabia. If lots of people have them, but only some have real power, the ones who don’t have power eventually turn on the ones who do.

“You have a situation now where there are many more elites fighting for the same position, and some portion of them will convert to counter-elites,” Turchin said.

Elite jobs do not multiply as fast as elites do. There are still only 100 Senate seats, but more people than ever have enough money or degrees to think they should be running the country

Turchin noted that a person can be part of an ideological elite rather than an economic one.

Elite overproduction creates counter-elites, and counter-elites look for allies among the commoners. If commoners’ living standards slip—not relative to the elites, but relative to what they had before—they accept the overtures of the counter-elites and start oiling the axles of their tumbrels

Commoners’ lives grow worse, and the few who try to pull themselves onto the elite lifeboat are pushed back into the water by those already aboard.

The final trigger of impending collapse, Turchin says, tends to be state insolvency. At some point rising in­security becomes expensive. The elites have to pacify unhappy citizens with handouts and freebies—and when these run out, they have to police dissent and oppress people.

Eventually the state exhausts all short-term solutions, and what was heretofore a coherent civilization disintegrates.

“I gave up because I solved the problem.” Turchin published one final monograph, Complex Population Dynamics: A Theoretical / Empirical Synthesis (2003), then broke the news to his UConn colleagues that he would be saying a permanent sayonara to the field

“Does population ecology have general laws?” Turchin asked. Most ecologists said no: Populations have their own dynamics, and each situation is different.

All sciences go through this transition to mathematization,” Turchin told me. “When I had my midlife crisis, I was looking for a subject where I could help with this transition to a mathematized science. There was only one left, and that was history.”

After its long adolescence of collecting and cataloging, ecology had enough data to describe these universal laws—and to stop pretending that every species had its own idiosyncrasies. “Ecologists know these laws and should call them laws,” he said.

The laws Turchin applied to ecology—and his insistence on calling them laws—­generated respectful controversy at the time. Now they are cited in textbooks.

Having left ecology, Turchin began similar research that attempted to formulate general laws for a different animal species: human beings.

Turchin suggested that “there are several very general law-like propositions” that could be applied to ecology.

If the historians weren’t going to usher in a mathematical revolution themselves, he would storm their departments and do it for them.

“There is a longstanding debate among scientists and philosophers as to whether history has general laws,” he and a co-author wrote in Secular Cycles (2009). “A basic premise of our study is that historical societies can be studied with the same methods physicists and biologists used to study natural systems.”

he likened historians reluctant to build general principles to his colleagues in biology “who care most for the private life of warblers.” “Let history continue to focus on the particular,” he wrote. Cliodynamics would be a new science

To seed the journal’s research, Turchin masterminded a digital archive of historical and archaeological data.

The coding of its records requires finesse, he told me, because (for example) the method of determining the size of the elite-aspirant class of medieval France might differ from the measure of the same class in the present-day United States. (For medieval France, a proxy is the membership in its noble class, which became glutted with second and third sons who had no castles or manors to rule over. One American proxy, Turchin says, is the number of lawyers.)

Historians of religion have long pondered the relationship between the rise of complex civilization and the belief in gods—especially “moralizing gods,” the kind who scold you for sinning. Last year, Turchin and a dozen co-authors mined the database (“records from 414 societies that span the past 10,000 years from 30 regions around the world, using 51 measures of social complexity and 4 measures of supernatural enforcement of morality”) to answer the question conclusively. They found that complex societies are more likely to have moralizing gods, but the gods tend to start their scolding after the societies get complex, not before

One of Turchin’s most unwelcome conclusions is that complex societies arise through war. The effect of war is to reward communities that organize themselves to fight and survive, and it tends to wipe out ones that are simple and small-scale

the data are clear: Darwinian processes select for complex socie­ties because they kill off simpler ones.

Certain aspects of this cyclical view require relearning portions of American history, with special attention paid to the numbers of elites. The industrialization of the North, starting in the mid-19th century, Turchin says, made huge numbers of people rich. The elite herd was culled during the Civil War, which killed off or impoverished the southern slaveholding class, and during Reconstruction, when America experienced a wave of assassinations of Republican politicians.

“There is a very close correlation between adopting democratic institutions and having to fight a war for survival.”

Also unwelcome: the conclusion that civil unrest might soon be upon us, and might reach the point of shattering the country. In 2012, Turchin published an analysis of political violence in the United States, again starting with a database. He classified 1,590 incidents—riots, lynchings, any political event that killed at least one person—from 1780 to 2010. Some periods were placid and others bloody, with peaks of brutality in 1870, 1920, and 1970, a 50-year cycle.

In 2010, when Nature surveyed scientists about their predictions for the coming decade, most took the survey as an invitation to self-promote and rhapsodize, dreamily, about coming advances in their fields. Turchin retorted with his prophecy of doom and said that nothing short of fundamental change would stop another violent turn.

It wasn’t until the Progressive reforms of the 1920s, and later the New Deal, that elite overproduction actually slowed, at least for a time.

This oscillation between violence and peace, with elite over­production as the first horseman of the recurring American apocalypse, inspired Turchin’s 2020 prediction

The notion that democracy finds its strength in its essential goodness and moral improvement over its rival systems is likewise fanciful. Instead, democratic societies flourish because they have a memory of being nearly obliterated by an external enemy. They avoided extinction only through collective action, and the memory of that collective action makes democratic politics easier to conduct in the present,

Some sound like ideas that might have come from Senator Elizabeth Warren—tax the elites until there are fewer of them

others, such as a call to reduce immigration to keep wages high for American workers, resemble Trumpian protectionism.

He opposes credential-­oriented higher education, for example, which he says is a way of mass-producing elites without also mass-­producing elite jobs for them to occupy. Architects of such policies, he told me, are “creating surplus elites, and some become counter-elites.” A smarter approach would be to keep the elite numbers small, and the real wages of the general population on a constant rise.

We need to stop the runaway process of elite overproduction, but I don’t know what will work to do that, and nobody else does. Do you increase taxation? Raise the minimum wage? Universal basic income?” He conceded that each of these possibilities would have unpredictable effects

practice “adaptive management,” changing and modulating your approach as you go.

Eventually, Turchin hopes, our understanding of historical dynamics will mature to the point that no government will make policy without reflecting on whether it is hurtling toward a mathematically pre­ordained disaster.

He says he could imagine an Asimovian agency that keeps tabs on leading indicators and advises accordingly. It would be like the Federal Reserve, but instead of monitoring inflation and controlling monetary supply, it would be tasked with averting total civilizational collapse.

Since at least the 19th century, the discipline has embraced the idea that history is irreducibly complex, and by now most historians believe that the diversity of human activity will foil any attempt to come up with general laws, especially predictive ones.

The idea that one thing causes another, and that the causal pattern can tell you about sequences of events in another place or century, is foreign territory.

Turchin counters that he has heard claims of irreducible complexity before, and that steady application of the scientific method has succeeded in managing that complexity.

One social scientist who can speak to Turchin in his own mathematical argot is Dingxin Zhao, a sociology professor at the University of Chicago who is—incredibly—­also a former mathematical ecologist.

in a way I am sympathetic to Turchin. If you come to social science from natural sciences, you have a powerful way of looking at the world. But you may also make big mistakes.”

Turchin is nonetheless filling a historiographical niche left empty by academic historians with allergies not just to science but to a wide-angle view of the past.

humans are much wilier social creatures, Zhao said. A woodpecker will eat a termite, but it “will not explain that he is doing so because it is his divine right.” Humans pull ideological power moves like this all the time, Zhao said, and to understand “the decisions of a Donald Trump, or a Xi Jinping,” a natural scientist has to incorporate the myriad complexities of human strategy, emotion, and belief. “I made that change,” Zhao told me, “and Peter Turchin has not.”

Zhao said that human beings are just much more complicated than bugs.

He places himself in a Russian tradition prone to thinking sweeping, Tolstoyan thoughts about the path of history. By comparison, American historians mostly look like micro-historians.

Rather than bending toward progress, the arc in his view bends all the way back on itself, in a never-­ending loop of boom and bust. This puts him at odds with American historians, many of whom harbor an unspoken faith that liberal democracy is the end state of all history.

Writing history in this sweeping, cyclical way is easier if you are trained outside the field. “If you look at who is doing these megahistories, more often than not, it’s not actual historians,”

The genre’s most famous book, Guns, Germs, and Steel (1997), beheld 13,000 years of human history in a single volume. Its author, Jared Diamond, spent the first half of his career as one of the world’s foremost experts on the physiology of the gall­bladder.

Steven Pinker, a cognitive psychologist who studies how children acquire parts of speech, has written a megahistory about the decline of violence across thousands of years, and about human flourishing since the Enlightenment

Most historians I asked about these men—and for some reason megahistory is nearly always a male pursuit—used terms like laughingstock and patently tendentious to describe them.

Pinker retorts that historians are resentful of the attention “disciplinary carpet­baggers” like himself have received for applying scientific methods to the humanities and coming up with conclusions that had eluded the old methods.

“Given the noisiness of human behavior and the prevalence of cognitive biases, it’s easy to delude oneself about a historical period or trend by picking whichever event suits one’s narrative,” he says. The only answer is to use large data sets.

“There’s no reason that traditional history and data science can’t merge into a cooperative enterprise,” Pinker wrote. “Knowing stuff is hard; we need to use every available tool.”

Turchin’s conclusions are only as good as his databases, she told me, and any database that tries to code something as complex as who constitutes a society’s elites—then tries to make like-to-like comparisons across millennia and oceans—will meet with skepticism from traditional historians

Turchin’s data are also limited to big-­picture characteristics observed over 10,000 years, or about 200 lifetimes. By scientific standards, a sample size of 200 is small, even if it is all humanity has.

Privately, some historians have told me they consider the tools he uses powerful, if a little crude. Clio­dynamics is now on a long list of methods that arrived on the scene promising to revolutionize history. Many were fads, but some survived that stage to take their rightful place in an expanding historiographical tool kit

Turchin’s methods have already shown their power. Cliodynamics offers scientific hypotheses, and human history will give us more and more opportunities to check its predictions—­revealing whether Peter Turchin is a Hari Seldon or a mere Nostradamus.

The economy that Hickel envisions would cease to pursue growth, green or otherwise. Materials and energy will still be consumed, and waste generated, but at much lower levels. All impacts on the natural world will be tethered to the question, “Growth for whom, and to what ends?” In place of an individualistic consumer economy, Hickel’s post-growth economy would direct itself toward the creation of public goods that allow the many to live well—mass transit, health care—rather than to keep a few in luxury.

A growing body of research reveals an inverse relationship between “happiness” and growth beyond a certain point.

In the rich countries, general contentment peaked in 1950, when GDP and real per capita incomes were fractions of their present size (and inequality near modern historic lows); degrowthers posit that similar happiness levels will be reclaimed on the way back down the economic mountain

Hickel describes a post-growth economy defined by stability and equality, and the freedom and leisure possible when the economy is no longer subservient to the god of growth

He estimates that the U.S. economy could be scaled down by as much as 65 percent while still improving the lives of its citizens. This includes the metric most often tied to celebrations of endless growth: life expectancy.

degrowth will entail a steep reduction across a much wider range of high-energy consumer goods. Keeping a global economy within safe ecological limits is a zero-sum game.

When limited resources are directed toward clean energy infrastructure, public health care, and regenerative agriculture, it will still be possible to build and power modern 24-hour hospitals in every city, but not to have Xbox consoles, two-car garages, and giant appliances in every home.

would have to redefine it, too.

The post-growth economy could not succeed solely by redistributing wealth; it would have to redefine it, too.

He argues that short-term growth would have to continue in those countries that have still not achieved the basic levels of sanitation, infrastructure, and education needed for a decent standard of living, to close the gap. Their larger goal, meanwhile, would be to break free from their historical role as a source of natural resources and cheap labor for the north.

For degrowth to be just, global, and effective, the sharpest reduction in consumption will have to come from the north, where the greatest damage to the planet is currently being done

Ecological economists generally agree that the safe outer limit is eight tons

One person in a low-income country has a materials footprint of roughly two tons per year, a measure of total raw materials consumed, including those embodied in imports. In lower-middle–income countries, that number is four tons; in upper-middle–income countries, 12 tons. In the high-income nations of North America, Europe, and Asia, the number leaps to 28

The wealthiest 20 percent of the human population is responsible for 90 percent of “overshoot” carbon in the atmosphere (that is, a level of carbon that exceeds the limit needed to keep global temperature rise below 2 degrees Celsius)

The planet’s richest one percent has a carbon footprint twice the size of the poorest half of the world’s population combined

For the global north, degrowth not only starts at home, it starts with the biggest houses.

Less Is More doesn’t end in a poetic appreciation for nature’s majesty, but by teasing out its implications for the political project of preserving a habitable planet. Hickel devotes much of the book to explaining that degrowth must be central to this project, promising not just survival, but real democracy, social abundance, and liberation.

Both involve broad social shifts away from private consumption and toward the production of shared public goods.

This beautiful coincidence overlaps with policy programs like the Green New Deal in important way

In July 1979, shortly after installing a set of solar panels over the West Wing, Jimmy Carter did something peculiar for a peacetime president. He asked Americans to sacrifice: to consume less, take public transit more, value community over material things, and buy bonds to fund domestic energy development, including solar

Next to Schumacher’s “Buddhist economics,” Debsian socialism was reformist tinkering. Schumacher didn’t see liberation as a matter of reshuffling the ownership and management structures of the smokestack-powered growth economy. He believed a deeper transformation was needed to maintain a livable planet. This would require new socioecological blueprints “designed for permanence.” As the left and the right battled for control over growth’s levers and spoils, Schumacher pointed out how both had become blind to the rise of growth as its own self-justifying, pan-ideological religion; its patterns of production and consumption, he observed, required “a degree of violence” that did not “fit into the laws of the universe.”

They determined that infinite growth was, in fact, impossible on a finite planet. Barring a major course correction, the team projected, growthism would result in an ecological systems breakdown sometime in the middle of the twenty-first century

This warning, detailed in the 1972 bestseller The Limits to Growth, has aged better than the scorn heaped on it

We are now witnessing what appears to be the beginnings of the collapse predicted nearly 50 years ago

In his new book, Less Is More, Jason Hickel, an anthropologist and journalist, attempts to bring a comprehensive critique of growth closer to the center of the conversation, arguing through a sweeping history of capitalism that it’s uncontrolled growth, not its controlled arrest and reversal, that is the preposterous concept.

This economic and political revolution was reinforced by a complementary scientific one that displaced the lingering animist cosmology of pre-capitalist Europe. The dualism of Francis Bacon and Descartes held reason to be distinct from and superior to matter.

The idea of limitless growth is a relatively recent one. In Less Is More, Hickel traces its origins to the enclosure of the European commons in the sixteenth century

Starving refugees were scattered and forced into a new economy defined by neo-feudal servitude and wage labor. Landowners, meanwhile, began amassing great stores of surplus wealth.

By the mid-1800s, a new “science” had arisen from these assumptions. Neoclassical economics fully abstracted the economy from the natural world. The economy was geared not toward the creation of a happy and prosperous society, but toward the perpetual growth of wealth as its own end, achieved in an inherently virtuous cycle of converting labor and resources into capital, to be accumulated and reinvested in faster and more productive conversions of labor and resources

This ideology subsumed and profaned notions about progress and morality held by the classical economists, until eventually the field even l

This process unfolded despite repeated warnings along the way. Classical economists like John Stuart Mill and, to a lesser extent, Adam Smith not only acknowledged the existence of natural limits to growth, but saw economic development as a phase; at some point, they believed, nations would create enough wealth to pursue other definitions of progres

the caveats issued by Simon Kuznets, father of the concept adopted in the twentieth century as growth’s universal and signature metric: gross domestic product. Kuznets, Hickel points out, “warned that we should never use GDP as a normal measure of economic progress,” because GDP does not distinguish between productive and destructive behavior

Most people encounter the growth debate, if they encounter it at all, through the idea of “green growth.

This is a vision for our collective future based on the belief that technological advance will drastically reduce the amount of raw materials needed to sustain growth—a process known as dematerialization—and “decouple” growing GDP from its ecological impacts.

boosters of the idea point to the transition by rich countries from manufacturing to service-based economies, as well as efficiency gains in energy and in the use of materials

The belief that green growth will save us, also known as “ecomodernism” or “ecopragmatism,” has become a trendy article of faith among elites who acknowledge climate change and the dangers of breaching ecological boundaries

n 2017, Barack Obama threw his support behind the idea in an article for Science magazine, maintaining that signs of decoupling in major economies “should put to rest the argument that combatting climate change requires accepting lower growth or a lower standard of living.”

The argument that capitalism can grow itself out of the present crisis may be soothing to those who like the world as it is. It also relies on the kind of accounting tricks and rejection of reality

By only counting the emissions created within a country that imports most of its cars, washing machines, and computers, you end up pushing the emissions related to their production off the books. When you factor them back in, the picture is much less green. A number of recent studies show no evidence of meaningful decoupling—in energy or materials—even as the world increases its use of renewable energy and finds ways to use some materials more efficiently.

Green growth, Hickel concludes, is an ecologically incoherent “fairy tale.”

consider what the ecomodernist position asks us to believe. The current system requires annual growth of roughly 3 percent to avoid the shock of recession. This means doubling the size of the economy every 23 years

he economy of 2000 must be 20 times larger in the year 2100, and 370 times larger in the year 2200.

Hickel is less interested in the macroeconomic details of this future than are growth critics based in economics departments, like Tim Jackson and Kate Raworth, and more focused on the leisure, security, and general human flourish

he makes an alluring case that degrowth does not require anything like the “command-and-control fiasco of the Soviet Union, or some back-to-the-caves, hair-shirted disaster of voluntary impoverishment.”

Attaining the benefits of the post-growth economy would, however, require what the present consumer society considers “sacrifices.

it’s not clear how many of them are ready to give up its superficial pleasures enabled by consumer debt

Among nations, there’s also the question of fairness: Wouldn’t it be unjust to impose degrowth across the world, when it’s disproportionately the countries of the global north that have spent centuries burning through the planet’s resources?

This output tracks to the one percent’s share of global wealth—a number equal to the GDP of the bottom 169 countries.

Even if you accept the argument that inequality would be best addressed by more centuries of trickle-down growth, you keep running up against the simple fact of its impossibility. Even just one more century of growth—which so far has shown no sign of taking a less destructive form—will require multiple earths

Hickel is serious about bringing the system critiques of E.F. Schumacher and others out of their traditional cloisters and into the streets, and has sought allies in this effort

emphasize what Hickel calls the “beautiful coincidence” of degrowth: that “what we need to do to survive is the same as what we need to do to have better lives.”

Both are internationalist in outlook, and see the world through a lens of climate justice as well as climate equilibrium.

that is, communicating the many benefits of moving beyond the insecurity and terrors of the current system, and building a new society that is sustainable, stable, democratic, and fundamentally better in every way.

most economists see global trade as a win-win proposition, but resource limitation turns it into a win-lose, zero-sum contest. “The faster China grows, the higher grain prices go, the more people in China or India who upgrade to meat, the higher the tendency for Africa to starve,” he said.

Grantham argues that the late-18th-century doomsayer Thomas Malthus pretty much got it right but just had the bad timing to make his predictions about unsustainable population growth on the eve of the hydrocarbon-fueled Industrial Revolution, which “partially removed the barriers to rapid population growth, wealth and scientific progress.” That put off the inevitable for a couple of centuries, but now, ready or not, the age of cheap hydrocarbons is ending. Grantham’s July letter concludes: “We humans have the brains and the means to reach real planetary sustainability. The problem is with us and our focus on short-term growth and profits, which is likely to cause suffering on a vast scale. With foresight and thoughtful planning, this suffering is completely avoidable.”

“E.D.F. is educating people that dealing with climate change will be good for the economy and job creation. One of Jeremy’s insights is that we can make headway on the market side because higher commodity prices will enforce greater efficiency.”

When he reminds us that modern capitalism isn’t equipped to handle long-range problems or tragedies of the commons (situations like overfishing or global warming, in which acting rationally in your own self-interest only deepens the harm to all), when he urges us to outgrow our touching faith in the efficiency of markets and boundless human ingenuity, and especially when he says that a wise investor can prosper in the coming hard times, his bad news and its silver lining come with a built-in answer to the skeptical question that Americans traditionally pose to egghead Cassandras: If you’re so smart, how come you’re not rich?

Grantham believes that the best approach may be to recast global warming, which depresses crop yields and worsens soil erosion, as a factor contributing to resource depletion. “People are naturally much more responsive to finite resources than they are to climate change,” he said. “Global warming is bad news. Finite resources is investment advice.”

“Americans are just about the worst at dealing with long-term problems, down there with Uzbekistan,” he said, “but they respond to a market signal better than almost anyone. They roll the dice bigger and quicker than most.”

Grantham, the public face of a company that manages more than $100 billion in assets, the very embodiment of a high-finance insider in blue blazer and yellow tie, has serious doubts about capitalism’s ability to address the biggest problems facing humanity.

Grantham says that corporations respond well to this message because they are “persuaded by data,” but American public opinion is harder to move, and contemporary American political culture is practically dataproof. “The politicians are the worst,” he said. “An Indian economist once said to me, ‘We have 28 political parties, and they all think climate change is important.’ ” Whatever the precise number of parties in India, and it depends on how you count, his point was that the U.S. has just two that matter, one that dismisses global warming as a hoax and one that now avoids the subject.

Grantham, who says that “this time it’s different are the four most dangerous words in the English language,” has become a connoisseur of bubbles. His historical study of more than 300 of them shows the same pattern occurring again and again. A bump in sales or some other impressive development causes people to get excited. When they do, the price of that asset class — South Sea company shares, dot-coms — goes up, and human nature and the financial industry conspire to push it higher. People want to hear good news; they tend to be bad with numbers and uncertainty, and to assume that present conditions will persist. In the financial industry, the imperative to minimize career risk produces herd behavior.

So it’s news when Grantham, who has built his career on the conviction that peaks and troughs will even out as prices inevitably revert to their historical mean, says that this time it really is different, and not in a good way. In his April letter, “Time to Wake Up: Days of Abundant Resources and Falling Prices Are Over Forever,” he argued that “we are in the midst of one of the giant inflection points in economic history.” The market is “sending us the Mother of all price signals,” warning us that “if we maintain our desperate focus on growth, we will run out of everything and crash.”

here’s the short version: “The prices of all important commodities except oil declined for 100 years until 2002, by an average of 70 percent. From 2002 until now, this entire decline was erased by a bigger price surge than occurred during World War II. Statistically, most commodities are now so far away from their former downward trend that it makes it very probable that the old trend has changed — that there is in fact a Paradigm Shift — perhaps the most important economic event since the Industrial Revolution.”

When prices go up and stay up, it’s not a bubble. Prices may always revert to the mean, but the mean can change; that’s a paradigm shift. As Grantham tells it, oil went first. For a century it steadily returned to about $16 a barrel in today’s currency, then in 1974 the mean shifted to about $35, and Grantham believes it has recently doubled again. Metals and nearly everything else — coal, corn, palm oil, soybeans, sugar, cotton — appear to be following suit. “From now on, price pressure and shortages of resources will be a permanent feature of our lives,” he argues. “The world is using up its natural resources at an alarming rate, and this has caused a permanent shift in their value. We all need to adjust our behavior to this new environment. It would help if we did it quickly.”

Grantham is taking the Malthusian side in an ongoing debate about growth and commodity prices­. The argument often circles back to the bet made in 1980 between the biologist Paul Ehrlich, who foretold catastrophic scarcity caused by overpopulation, and the economist Julian Simon, who argued that any short-term increase in resource prices caused by population growth will stimulate inventors and entrepreneurs to find new ways to exploit those resources, lowering prices in the long run. The two men picked five commodities and wagered on whether their prices, taken as an indicator of scarcity, would be higher or lower in 1990. Simon won, 5-0, even though the world’s population grew by 800 million during that decade. Malthusians have been trying to live down that defeat ever since, but, as Grantham points out in his July letter, if we extend the original bet past its arbitrary 10-year limit to the present day, Ehrlich wins the five-commodity bet 4-1, and he wins big if the bet is further extended to all important commodities.

He’s an impassioned environmentalist not only for the usual reasons but also because he believes humanity’s vexed relationship with the planet is the great economic story of our time. “This commodities thing may turn out to be the most interesting call of my career,” he told me. “I have no doubt we’re going to have a bad hundred years. We have the resources to gracefully handle the transition, but we won’t. We apparently can’t.”

“Whether the stable population will be 1.5 billion or 5 billion,” he said to me, “the question is: How do we get there?”

titled “Tightness-Looseness Across the 50 United States,” the study calculated a catalog of measures for each state, including the incidence of natural disasters, disease prevalence, residents’ levels of openness and conscientiousness, drug and alcohol use, homelessness and incarceration rates.

Gelfand said:Some groups have much stronger norms than others; they’re tight. Others have much weaker norms; they’re loose. Of course, all cultures have areas in which they are tight and loose — but cultures vary in the degree to which they emphasize norms and compliance with them.

states in New England and on the West Coast were the loosest: California, Oregon, Washington, Maine, Massachusetts, Connecticut, New Hampshire and Vermont.

In both 2016 and 2020, Donald Trump carried all 10 of the top “tight” states; Hillary Clinton and Joe Biden carried all 10 of the top “loose” states.

“Rule Makers, Rule Breakers: How Tight and Loose Cultures Wire the World” in 2018, in which she described the results of a 2016 pre-election survey she and two colleagues had commissioned

The results were telling: People who felt the country was facing greater threats desired greater tightness. This desire, in turn, correctly predicted their support for Trump. In fact, desired tightness predicted support for Trump far better than other measures. For example, a desire for tightness predicted a vote for Trump with 44 times more accuracy than other popular measures of authoritarianism.

The 2016 election, Gelfand continued, “turned largely on primal cultural reflexes — ones that had been conditioned not only by cultural forces, but by a candidate who was able to exploit them.”

Along the same lines, if liberals and conservatives hold differing moral visions, not just about what makes a good government but about what makes a good life, what turned the relationship between left and right from competitive to mutually destructive?

Cultural differences, Gelfand continued, “have a certain logic — a rationale that makes good sense,” noting that “cultures that have threats need rules to coordinate to survive (think about how incredibly coordinated Japan is in response to natural disasters).

cultures that don’t have a lot of threat can afford to be more permissive and loose.”

The tight-loose concept, Gelfand argued,is an important framework to understand the rise of President Donald Trump and other leaders in Poland, Hungary, Italy, and France,

The gist is this: when people perceive threat — whether real or imagined, they want strong rules and autocratic leaders to help them survive

My research has found that within minutes of exposing study participants to false information about terrorist incidents, overpopulation, pathogen outbreaks and natural disasters, their minds tightened. They wanted stronger rules and punishments.

The South dominated the tight states: Mississippi, Alabama Arkansas, Oklahoma, Tennessee, Texas, Louisiana, Kentucky, South Carolina and North Carolina

Looseness, Gelfand posits, fosters tolerance, creativity and adaptability, along with such liabilities as social disorder, a lack of coordination and impulsive behavior.

If liberalism and conservatism have historically played a complementary role, each checking the other to constrain extremism, why are the left and right so destructively hostile to each other now, and why is the contemporary political system so polarized?

Gelfand writes that tightness encourages conscientiousness, social order and self-control on the plus side, along with close-mindedness, conventional thinking and cultural inertia on the minus side.

Niemi contended that sensitivity to various types of threat is a key factor in driving differences between the far left and far right.

She cited research thatfound 47 percent of the most extreme conservatives strongly endorsed the view that “The world is becoming a more and more dangerous place,” compared to 19 percent of the most extreme liberals

Conservatives and liberals, Niemi continued,see different things as threats — the nature of the threat and how it happens to stir one’s moral values (and their associated emotions) is a better clue to why liberals and conservatives react differently.

Unlike liberals, conservatives strongly endorse the binding moral values aimed at protecting groups and relationships. They judge transgressions involving personal and national betrayal, disobedience to authority, and disgusting or impure acts such as sexually or spiritually unchaste behavior as morally relevant and wrong.

Underlying these differences are competing sets of liberal and conservative moral priorities, with liberals placing more stress than conservatives on caring, kindness, fairness and rights — known among scholars as “individualizing values

conservatives focus more on loyalty, hierarchy, deference to authority, sanctity and a higher standard of disgust, known as “binding values.”

As a set, Niemi wrote, conservative binding values encompassthe values oriented around group preservation, are associated with judgments, decisions, and interpersonal orientations that sacrifice the welfare of individuals

Just as ecological factors differing from region to region over the globe produced different cultural values, ecological factors differed throughout the U.S. historically and today, producing our regional and state-level dimensions of culture and political patterns.

Niemi cited a paper she and Liane Young, a professor of psychology at Boston College, published in 2016, “When and Why We See Victims as Responsible: The Impact of Ideology on Attitudes Toward Victims,” which tested responses of men and women to descriptions of crimes including sexual assaults and robberies.

We measured moral values associated with unconditionally prohibiting harm (“individualizing values”) versus moral values associated with prohibiting behavior that destabilizes groups and relationships (“binding values”: loyalty, obedience to authority, and purity)

Increased endorsement of binding values predicted increased ratings of victims as contaminated, increased blame and responsibility attributed to victims, increased perceptions of victims’ (versus perpetrators’) behaviors as contributing to the outcome, and decreased focus on perpetrators.

For example, binding values are associated with Machiavellianism (e.g., status-seeking and lying, getting ahead by any means, 2013); victim derogation, blame, and beliefs that victims were causal contributors for a variety of harmful acts (2016, 2020); and a tendency to excuse transgressions of ingroup members with attributions to the situation rather than the person (2023).

What happened to people ecologically affected social-political developments, including the content of the rules people made and how they enforced them

Numerous factors potentially influence the evolution of liberalism and conservatism and other social-cultural differences, including geography, topography, catastrophic events, and subsistence styles

Joshua Hartshorne, who is also a professor of psychology at Boston College, took issue with the binding versus individualizing values theory as an explanation for the tendency of conservatives to blame victims:

I would guess that the reason conservatives are more likely to blame the victim has less to do with binding values and more to do with the just-world bias (the belief that good things happen to good people and bad things happen to bad people, therefore if a bad thing happened to you, you must be a bad person).

Belief in a just world, Hartshorne argued, is crucial for those seeking to protect the status quo:It seems psychologically necessary for anyone who wants to advocate for keeping things the way they are that the haves should keep on having, and the have-nots have got as much as they deserve. I don’t see how you could advocate for such a position while simultaneously viewing yourself as moral (and almost everyone believes that they themselves are moral) without also believing in the just world

Conversely, if you generally believe the world is not just, and you view yourself as a moral person, then you are likely to feel like you have an obligation to change things.

I asked Lene Aaroe, a political scientist at Aarhus University in Denmark, why the contemporary American political system is as polarized as it is now, given that the liberal-conservative schism is longstanding. What has happened to produce such intense hostility between left and right?

There is variation across countries in hostility between left and right. The United States is a particularly polarized case which calls for a contextual explanatio

A central explanation typically offered for the current situation in American politics is that partisanship and political ideology have developed into strong social identities where the mass public is increasingly sorted — along social, partisan, and ideological lines.

I then asked Aaroe why surveys find that conservatives are happier than liberals. “Some research,” she replied, “suggests that experiences of inequality constitute a larger psychological burden to liberals because it is more difficult for liberals to rationalize inequality as a phenomenon with positive consequences.”

Steven Pinker, a professor of psychology at Harvard, elaborated in an email on the link between conservatism and happiness:

t’s a combination of factors. Conservatives are likelier to be married, patriotic, and religious, all of which make people happier

They may be less aggrieved by the status quo, whereas liberals take on society’s problems as part of their own personal burdens. Liberals also place politics closer to their identity and striving for meaning and purpose, which is a recipe for frustration.

Some features of the woke faction of liberalism may make people unhappier: as Jon Haidt and Greg Lukianoff have suggested, wokeism is Cognitive Behavioral Therapy in reverse, urging upon people maladaptive mental habits such as catastrophizing, feeling like a victim of forces beyond one’s control, prioritizing emotions of hurt and anger over rational analysis, and dividing the world into allies and villains.

Why, I asked Pinker, would liberals and conservatives react differently — often very differently — to messages that highlight threat?

It may be liberals (or at least the social-justice wing) who are more sensitive to threats, such as white supremacy, climate change, and patriarchy; who may be likelier to moralize, seeing racism and transphobia in messages that others perceive as neutral; and being likelier to surrender to emotions like “harm” and “hurt.”

The authors used neural imaging to follow changes in the dorsomedial prefrontal cortex (known as DMPFC) as conservatives and liberals watched videos presenting strong positions, left and right, on immigration.

there are ways to persuade conservatives to support liberal initiatives and to persuade liberals to back conservative proposals:

While liberals tend to be more concerned with protecting vulnerable groups from harm and more concerned with equality and social justice than conservatives, conservatives tend to be more concerned with moral issues like group loyalty, respect for authority, purity and religious sanctity than liberals are. Because of these different moral commitments, we find that liberals and conservatives can be persuaded by quite different moral arguments

For example, we find that conservatives are more persuaded by a same-sex marriage appeal articulated in terms of group loyalty and patriotism, rather than equality and social justice.

“political arguments reframed to appeal to the moral values of those holding the opposing political position are typically more effective

We find support for these claims across six studies involving diverse political issues, including same-sex marriage, universal health care, military spending, and adopting English as the nation’s official language.”

In one test of persuadability on the right, Feinberg and Willer assigned some conservatives to read an editorial supporting universal health care as a matter of “fairness (health coverage is a basic human right)” or to read an editorial supporting health care as a matter of “purity (uninsured people means more unclean, infected, and diseased Americans).”

Conservatives who read the purity argument were much more supportive of health care than those who read the fairness case.

Liberals who read the fairness argument were substantially more supportive of military spending than those who read the loyalty and authority argument.

In “Conservative and Liberal Attitudes Drive Polarized Neural Responses to Political Content,” Willer, Yuan Chang Leong of the University of Chicago, Janice Chen of Johns Hopkins and Jamil Zaki of Stanford address the question of how partisan biases are encoded in the brain:

society. How do such biases arise in the brain? We measured the neural activity of participants watching videos related to immigration policy. Despite watching the same videos, conservative and liberal participants exhibited divergent neural responses. This “neural polarization” between groups occurred in a brain area associated with the interpretation of narrative content and intensified in response to language associated with risk, emotion, and morality. Furthermore, polarized neural responses predicted attitude change in response to the videos.

The four authors argue that their “findings suggest that biased processing in the brain drives divergent interpretations of political information and subsequent attitude polarization.” These results, they continue, “shed light on the psychological and neural underpinnings of how identical information is interpreted differently by conservatives and liberals.”

While liberals and conservatives, guided by different sets of moral values, may make agreement on specific policies difficult, that does not necessarily preclude consensus.

or each video,” they write,participants with DMPFC activity time courses more similar to that of conservative-leaning participants became more likely to support the conservative positio

Conversely, those with DMPFC activity time courses more similar to that of liberal-leaning participants became more likely to support the liberal position. These results suggest that divergent interpretations of the same information are associated with increased attitude polarizatio

Together, our findings describe a neural basis for partisan biases in processing political information and their effects on attitude change.

Describing their neuroimaging method, the authors point out that theysearched for evidence of “neural polarization” activity in the brain that diverges between people who hold liberal versus conservative political attitudes. Neural polarization was observed in the dorsomedial prefrontal cortex (DMPFC), a brain region associated with the interpretation of narrative content.

The question is whether the political polarization that we are witnessing now proves to be a core, encoded aspect of the human mind, difficult to overcome — as Leong, Chen, Zaki and Willer sugges

— or whether, with our increased knowledge of the neural basis of partisan and other biases, we will find more effective ways to manage these most dangerous of human predispositions.

But the system works. In the dorms, classrooms, summer internships and early jobs they learn how to behave the way successful people do in the highly educated hubs. There’s no economic reason to return home, and maybe it’s not even socially possible anymore.

The highly educated cluster around a few small nodes. Decade after decade, smart and educated people flock away from Merced, Calif., Yuma, Ariz., Flint, Mich., and Vineland, N.J. In those places, less than 15 percent of the residents have college degrees. They flock to Washington, Boston, San Jose, Raleigh-Durham and San Francisco. In those places, nearly 50 percent of the residents have college degrees.

the magnet places have positive ecologies that multiply innovation, creativity and wealth. The abandoned places have negative ecologies and fall further behind.

This sorting is self-reinforcing, and it seems to grow more unforgiving every year.

half of the jobs in university political science programs went to graduates of the top 11 schools. That is to say, if you have a Ph.D. from Harvard, Stanford, Princeton and so on, your odds of getting a job are very good. If you earned your degree from one of the other 100 degree-granting universities, your odds are not.

The first problem with the effort is that it’s like shooting a water gun into a waterfall

The second problem is the focus on income redistribution

The final problem is that, in an effort to reduce the economic concentration of power, the administration is concentrating political power in Washington

the liberal agenda is not very good at addressing the inequality problem it seeks to solve. The meritocracy is overwhelming the liberal project.

for any closet revolutionary who has ever dreamed of overthrowing the present economic order in favour of one a little less likely to cause Italian pensioners to hang themselves in their homes, this work should be of particular interest. Because it makes the ditching of that cruel system in favour of something new (and perhaps, with lots of work, better) no longer a matter of mere ideological preference but rather one of species-wide existential necessity.

Anderson points out that we have lost so much time to political stalling and weak climate policies – all while global consumption (and emissions) ballooned – that we are now facing cuts so drastic that they challenge the fundamental logic of prioritising GDP growth above all else.

Anderson and Bows argue that, if the governments of developed countries are serious about hitting the agreed upon international target of keeping warming below 2° Celsius, and if reductions are to respect any kind of equity principle (basically that the countries that have been spewing carbon for the better part of two centuries need to cut before the countries where more than a billion people still don’t have electricity), then the reductions need to be a lot deeper, and they need to come a lot sooner.

To have even a 50/50 chance of hitting the 2° target (which, they and many others warn, already involves facing an array of hugely damaging climate impacts), the industrialised countries need to start cutting their greenhouse-gas emissions by something like 10 per cent a year – and they need to start right now.

a 10 per cent drop in emissions, year after year, is virtually unprecedented since we started powering our economies with coal. In fact, cuts above 1 per cent per year “have historically been associated only with economic recession or upheaval”, as the economist Nicholas Stern put it in his 2006 report for the British government.

Only in the immediate aftermath of the great market crash of 1929 did the United States, for instance, see emissions drop for several consecutive years by more than 10 per cent annually, according to historical data from the Carbon Dioxide Information Analysis Centre

If we are to avoid that kind of carnage while meeting our science-based emissions targets, carbon reduction must be managed carefully through what Anderson and Bows describe as “radical and immediate de-growth strategies in the US, EU and other wealthy nations”. Which is fine, except that we happen to have an economic system that fetishises GDP growth above all else, regardless of the human or ecological consequences, and in which the neoliberal political class has utterly abdicated its responsibility to manage anything (since the market is the invisible genius to which everything must be entrusted).

in order to appear reasonable within neoliberal economic circles, scientists have been dramatically soft-peddling the implications of their research. By August 2013, Anderson was willing to be even more blunt, writing that the boat had sailed on gradual change. “Perhaps at the time of the 1992 Earth Summit, or even at the turn of the millennium, 2°C levels of mitigation could have been achieved through significant evolutionary changes within the political and economic hegemony. But climate change is a cumulative issue! Now, in 2013, we in high-emitting (post-)industrial nations face a very different prospect. Our ongoing and collective carbon profligacy has squandered any opportunity for the ‘evolutionary change’ afforded by our earlier (and larger) 2°C carbon budget. Today, after two decades of bluff and lies, the remaining 2°C budget demands revolutionary change to the political and economic hegemony” (his emphasis).

there are many people who are well aware of the revolutionary nature of climate science. It’s why some of the governments that decided to chuck their climate commitments in favour of digging up more carbon have had to find ever more thuggish ways to silence and intimidate their nations’ scientists

If you want to know where this leads, check out what’s happening in Canada, where I live. The Conservative government of Stephen Harper has done such an effective job of gagging scientists and shutting down critical research projects that, in July 2012, a couple thousand scientists and supporters held a mock-funeral on Parliament Hill in Ottawa, mourning “the death of evidence”. Their placards said, “No Science, No Evidence, No Truth”.

“The pope’s ideas will be jarring to a modern reader at first. He says that people should not ascribe to the market magical qualities that can solve all problems.”

“Humanity is called to recognize the need for changes of lifestyle, production and consumption, in order to combat this warming or at least the human causes which produce or aggravate it,” the pope wrote. “At one extreme, we find those who doggedly uphold the myth of progress and tell us that ecological problems will solve themselves simply with the application of new technology and without any need for ethical considerations or deep change.”

“He’s rather brilliantly brought back a concept that has been lost for 30 years or so, since the beginning of the Reagan administration — he says profit-making can’t be the sole criteria for decision-making,

While the pope’s arguments against markets are likely to play poorly in Washington, they could play well in Latin American nations, especially Brazil. That nation, one of the world’s largest polluters, has a majority Roman Catholic population and has resisted devising an aggressive climate change policy, in part because of its struggles with poverty.

The pope said several times that developed economies owed a debt to poor nations. “A true ‘ecological debt’ exists, particularly between the global north and south, connected to commercial imbalances with effects on the environment, and the disproportionate use of natural resources by certain countries over long periods of time,”

The group has previously estimated that, in the Americas, nature itself—animals, plants, soil, water, all of it—is worth about twenty-four trillion dollars to us, an implausibly specific figure that makes the costs of degradation both more and less concrete.

“I think fundamentally we’ve got to get the message across that this is a crisis for humanity that could signal the end of human civilization as we know it. It’s not about animals somewhere off in the Arctic. It’s about the life that we lead, and whether we can keep leading it, and the chaos and violence that could ensue if we don’t do something immediately.”

“Even as someone who is basically an alarmist, it seemed really up in your face,” Wallace-Wells said of the group’s name and messaging. “But I also think, like, you kind of can’t argue with the results.”

Extinction Rebellion considers climate change and looming mass extinctions as intersecting but separate and potentially competing issues. In a statement last week, in response to the I.P.B.E.S. report, the group said that “too much of the focus has been on greenhouse gases and climate change. We also face an ecological crisis—the sixth mass extinction—which is as dangerous for our planet as climate change.” Jonathan Franzen said much the same, in this magazine, in 2015, describing climate change as a “usefully imponderable” problem compared to the threat of mass extinctions.

“There’s places where you’re losing habitat because temperatures are increasing, climate ranges are shifting north,

One third of the planet right now is in production of agriculture, and only about half of that is actually agriculture that has any kind of mind for the wildlife-habitat benefits that could be provided by just doing things slightly differently.”

“We’re trying to convince folks that, like, if we save nature, we save ourselves,” he continued. “If you have healthy habitats, we have healthy wildlife populations with clean water—all of that can help reduce emissions.”

Environmental groups insist that the sage grouse, just one of the countless bird species now thought to be at risk, really matters, and not only because undermining protections for it would be a boon for the fossil-fuel industries.

“It’s not just the sage grouse, right?” O’Mara said. “It’s the pronghorn. It’s the pygmy rabbit, the sagebrush vole. There’s a series of smaller species and bigger species that—if the sage grouse is healthy, that means the bigger ecosystem is doing pretty well. There’s three hundred and fifty other species that are likely doing O.K. if this one indicator species is doing O.K.”

the reality is that you have folks in both parties that deeply care about wildlife.”

We could all be doing more, but there’s maybe no greater separation between Democrats and Republicans today than on climate and pollution.”

Unlike climate change, the extinction crisis offers no clear targets to race toward or timelines to stick to. But addressing both will require, instead, a million revolutions, large and small, in the way we interact with and think about the natural world.

The relationship between ecology and capitalism is already emerging in the public conversation as a new paradigm, as political groups reassess their ideological foundations: those who believe that ecology and market economy are compatible compete against more radical advocates of a complete change of our growth model

There is a silver lining to this European upheaval, and it is an important one: the search for a better system is on, and citizens want to be part of the solution, as the large turnout at the European elections has shown. Europe is being turned into a giant political laboratory. Stay tuned.

or the first time, the threat of planetary security exceeded national security in the public imagination.

At the same time, the U.S. Department of Defense (DoD) was grappling with the national security implications of global climate change. A 2003 DoD report noted the potential for “military confrontation…triggered by a desperate need for natural resources such as energy, food, and water rather than by conflicts over ideology, religion, or national honor.”

According to Masco, “to attend to the shrinking arctic ice caps or the intensifying weather patterns is to reject the idea of a national security and replace it with a planetary vision of sustainability.

The primary resource for detailing the path of human evolution will always be fossil specimens.

In devising such scenarios and filling in the human family bush, researchers must consult a large and diverse array of fossils, and they must also employ refined excavation methods and records, geochemical dating techniques, and data from other specialized fields such as genetics, ecology and paleoecology, and ethology (animal behaviour)—in short, all the tools of the multidisciplinary science of paleoanthropology.

It is generally agreed that the taproot of the human family shrub is to be found among apelike species of the Middle Miocene Epoch (roughly 16–11.6 mya) or Late Miocene Epoch (11.6–5.3 mya). Genetic data based on molecular clock estimates support a Late Miocene ancestry. Various Eurasian and African Miocene primates have been advocated as possible ancestors to the early hominins, which came on the scene during the Pliocene Epoch (5.3–2.6 mya)

It's an ecological disaster so big, the army have been called in.

But scientists are now worried about many endangered species - including the Kangaroo Island dunnart, a mouse-like marsupial, and the glossy black-cockatoo.

"We're struggling to look for remnants of intact vegetation where some species may still be present," says Caroline, tearfully.

"A lot of the flora and fauna there are distinctive because a lot of the island's habitats remained fairly pristine. It's like stepping back in time when you cross to Kangaroo Island.

Kangaroo Island is one of Australia's most important wildlife sanctuaries, renowned for its biodiversity. Now it's feared that half of the island (more than 215,000 hectares) has been scorched.

"They are likely to have perished in the flames and for those who've survived, their habitats are gone," says Prof Dickman.

"We have no way of knowing exactly what has been lost. [But] if you don't have habitat, you don't have species."

It's estimated that half of the Kangaroo Island's 50,000 koalas have perished in the fires - a huge loss for a population that was thriving here.

A section of the outside grounds has been turned into a makeshift clinic. Volunteers race to treat as many animals as possible.

And, says Sam, the worst may not be over.

The global rate of consumption growth, before the pandemic, was 3% a year. Population growth is 1%. Some people assume this means that the rise in population bears one-third of the responsibility for increased consumption

But population growth is overwhelmingly concentrated among the world’s poorest people, who have scarcely any A or T to multiply their P. The extra resource use and greenhouse gas emissions caused by a rising human population are a tiny fraction of the impact of consumption growth.

Yet it is widely used as a blanket explanation of environmental breakdown.

Panic about population growth enables the people most responsible for the impacts of rising consumption (the affluent) to blame those who are least responsible.

At this year’s World Economic Forum in Davos, the primatologist Dame Jane Goodall, who is a patron of the charity Population Matters, told the assembled pollutocrats, some of whom have ecological footprints thousands of times greater than the global average: “All these things we talk about wouldn’t be a problem if there was the size of population that there was 500 years ago.”

If we had the global population of 500 years ago (around 500 million), and if it were composed of average UK plane passengers, our environmental impact would probably be greater than that of the 7.8 billion alive today.

he proposed no mechanism by which her dream might come true. This could be the attraction. The very impotence of her call is reassuring to those who don’t want change. If the answer to environmental crisis is to wish other people away, we might as well give up and carry on consuming.

Since the clergymen Joseph Townsend and Thomas Malthus wrote their tracts in the 18th century, poverty and hunger have been blamed not on starvation wages, war, misrule and wealth extraction by the rich, but on the reproduction rates of the poor.

Winston Churchill blamed the Bengal famine of 1943, that he helped to cause through the mass export of India’s rice, on the Indians “breeding like rabbits”. In 2013 Sir David Attenborough, also a patron of Population Matters, wrongly blamed famines in Ethiopia on “too many people for too little land”, and suggested that sending food aid was counter-productive.

Malthusianism slides easily into racism.

Most of the world’s population growth is happening in the poorest countries, where most people are black or brown. The colonial powers justified their atrocities by fomenting a moral panic about “barbaric”, “degenerate” people “outbreeding” the “superior races”

These claims have been revived today by the far right, who promote conspiracy theories about “white replacement” and “white genocide”. When affluent white people wrongly transfer the blame for their environmental impacts on to the birthrate of much poorer brown and black people, their finger-pointing reinforces these narratives. It is inherently racist.

The far right now uses the population argument to contest immigration into the US and the UK

how do we distinguish proportionate concerns about these harms from deflection and racism? Well, we know that the strongest determinant of falling birth rates is female emancipation and education. The major obstacle to female empowerment is extreme poverty. Its effect is felt disproportionately by women.

So a good way of deciding whether someone’s population concerns are genuine is to look at their record of campaigning against structural poverty.

Have they contested the impossible debts poor nations are required to pay? Have they argued against corporate tax avoidance, or extractive industries that drain wealth from poorer countries, leaving almost nothing behind

Or have they simply sat and watched as people remain locked in poverty, then complained about their fertility?

Before long, this reproductive panic will disappear. Nations will soon be fighting over immigrants: not to exclude them, but to attract them, as the demographic transition leaves their ageing populations with a shrinking tax base and a dearth of key workers.

we are firmly in a transition from a Middle East shaped by great powers to a Middle East shaped by Mother Nature.

We are just at the start of this paradigm shift from resistance to resilience, as this region starts to become too hot, too populated and too water-starved to sustain any quality of life.

et’s go back to Biden. He was dead right: America’s presence in Afghanistan and tacit security guarantees around the region were both stabilizing and enabling a lot of bad behavior — boycotts, occupations, reckless adventures and brutal interventions.

President Barack Obama’s pullback from the region and President Donald Trump’s refusal to retaliate against Iran — after it sent a wave of drones to attack a key Saudi oil facility in 2019 — were the warning signs that America had grown weary of intervening and refereeing in the Middle East’s sectarian wars. Biden just made it official.

“The U.S. is not pulling out entirely, but it is pulling back, and all of its Sunni Arab partners are now acting to protect themselves — and to stabilize the region — in an era when the U.S. will no longer be dominant there,”

“But the U.S. will still be needed to deter Iran, should it develop a nuclear capability — and to defuse other conflicts.”

just as we once supplanted the Soviets as the dominant shaper in the region, Mother Nature is now supplanting America as the dominant force.

In Mother Nature’s Middle East, leaders will be judged not by how much they resist one another or great powers, but by how much resilience they build for their people and nations at a time when the world will be phasing out fossil fuels, at a time when all the Arab-Muslim states have booming populations under the age of 30 and at a time of intensifying climate change.

The United Nations recently reported that Afghanistan has been hit with the worst drought in more than 30 years. It is crushing farmers, pushing up food prices and putting 18.8 million Afghans — nearly half of the population — into food insecurity. Over to you, Mr. Taliban: You broke it, you own it.

there may be a day, very soon, where the United States will need to return to active Israeli-Palestinian diplomacy — not based on land for peace, but sun and fresh water for peace. EcoPeace Middle East, an alliance of Israeli, Palestinian and Jordanian environmentalists, recently put forward just such a strategy called the “Green Blue Deal.”

How would it work? Jordan, with its vast desert areas, has the comparative advantage to produce large amounts of cheap solar electricity to meet its own needs and also to sell to the Israeli and Palestinian grids to “generate the electricity for desalination plants that could provide all three parties abundant fresh water,”

All the parties there are ecologically interdependent, but they have unhealthy interdependencies rather than healthy ones. America could become the trusted mediator who forges healthy interdependencies

Francis summarized accepted science and again took aim at skeptics who deny human-made climate change. He strayed beyond climate, couching artificial intelligence as representative of a worrying inclination to “increase human power beyond anything imaginable.”

“We must move beyond the mentality of appearing to be concerned but not having the courage needed to produce substantial changes,” the pope wrote.

In his new document, Francis noted how little world leaders have accomplished since then and blamed an absence of mechanisms to hold countries to their commitments, along with a “failure of conscience and responsibility.”

A Vatican delegation that attended the Paris negotiations was credited with helping to influence commitments from Poland and Catholic countries in Latin America.

Francis — who took the name of the patron saint of ecology — stands out among popes in his push to make environmentalism a core part of the faith.

He continued: “To the powerful, Pope Francis dares to repeat this question: ‘Why do you want to preserve today a power that will be remembered for its inability to intervene when it was urgent and necessary to do so?’”

Francis focused on what he described as a broken multilateral system for global decision-making and avoided calling on Catholics to take specific steps to combat climate change.

According to the Pew Research Center, 54 percent of American Catholics say the planet is warming mostly because of human activity — in line with the average among all American adults, but well behind the 90 percent figure among atheists.

“It is safe to say that many Catholics still do not view care for the environment as a central aspect of what it means to be a Catholic,” said David Cloutier, a professor of moral theology at Catholic University. “They view it as an optional activity that some Catholics might be involved in on the side, not a central commitment. But Pope Francis clearly is trying to move the church in that direction.”

The new projection, released on Monday, was carried out by the Earth4All collective of leading environmental science and economic institutions, including the Potsdam Institute for Climate Impact Research, Stockholm Resilience Centre and the BI Norwegian Business School. They were commissioned by the Club of Rome for a followup to its seminal Limits to Growth study more than 50 years ago.

“This gives us evidence to believe the population bomb won’t go off, but we still face significant challenges from an environmental perspective. We need a lot of effort to address the current development paradigm of overconsumption and overproduction, which are bigger problems than population.”

Previous studies have painted a grimmer picture. Last year, the UN estimated the world population would hit 9.7 billion by the middle of the century and continue to rise for several decades afterwards.

But the authors caution that falling birthrates alone will not solve the planet’s environmental problems, which are already serious at the 7.8 billion level and are primarily caused by the excess consumption of a wealthy minority.

The report is based on a new methodology which incorporates social and economic factors that have a proven impact on birthrate, such as raising education levels, particularly for women, and improving income.

In the business-as-usual case, it foresees existing policies being enough to limit global population growth to below 9 billion in 2046 and then decline to 7.3 billion in 2100.

too little too late: “Although the scenario does not result in an overt ecological or total climate collapse, the likelihood of regional societal collapses nevertheless rises throughout the decades to 2050, as a result of deepening social divisions both internal to and between societies. The risk is particularly acute in the most vulnerable, badly governed and ecologically vulnerable economies.”

In the second, more optimistic scenario – with governments across the world raising taxes on the wealthy to invest in education, social services and improved equality – it estimates human numbers could hit a high of 8.5 billion as early as 2040 and then fall by more than a third to about 6 billion in 2100. Under this pathway, they foresee considerable gains by mid-century for human society and the natural environment.

“By 2050, greenhouse gas emissions are about 90% lower than they were in 2020 and are still falling,” according to the report. “Remaining atmospheric emissions of greenhouse gases from industrial processes are increasingly removed through carbon capture and storage. As the century progresses, more carbon is captured than stored, keeping the global temperature below 2C above pre-industrial levels. Wildlife is gradually recovering and starting to thrive once again in many places.”

About 4,000 years ago, people started burning the forest, which was mostly bamboo, just enough to make small openings. They may have planted maize or squash, weeded out some underbrush, and transported seeds or saplings to create a partly curated forest of useful tree products that Dr. Watling calls a “prehistoric supermarket.” After that, they started building the geoglyphs. The presence of just a few artifacts, and the layout of the earthworks, suggest they weren’t used as ancient villages or for military defenses. They were likely built for rituals, some archaeologists suspect.

in contrast with the large-scale deforestation we see today — which threatens about 20 percent of the largest rain forest in the world — ancient indigenous people of the Amazon practiced something more akin to what we now call agroforestry. They restricted burns to site locations and maintained the surrounding landscape, creating small, temporary clearings in the bamboo and promoting the growth of plants like palm, cedar and Brazil nut that were, and still are, useful commodities. Today, indigenous groups around the world continue these sustainable practices in forests.
