The Earth itself is our greatest ally in this effort. Ecosystems like California’s kelp forests absorb about half of the greenhouse gases humans emit, studies show. Without them, warming would be even worse. Nature shields us from the worst consequences of our own actions, forgiving the sins we refuse to repent.

If we hope to solve climate change, humanity must also address this biodiversity crisis — restoring ecosystems and the creatures that inhabit them.

One way to revitalize ecosystems: protect the ground they grow from.Think of the soft, spongy soil of an old-growth woodland. Here, a towering oak tree draws up water and nutrients via threadlike fungi attached to its roots. In exchange, the fungi take sugar from the oak, funneling carbon from the air into the ground.Now imagine a leaf from that oak drifting slowly to the forest floor. Perhaps it becomes food for an earthworm. Then microbes attack the earthworm’s droppings, breaking down the residue further still.Eventually, the carbon that was once a leaf can become trapped in clods of earth. Other atoms may form strong chemical bonds with minerals like iron, which prevents them from reacting with oxygen and returning to the air. Under the right conditions, carbon might stay locked away in dense, dark earth for centuries. Soils contain more carbon than the entire atmosphere and all the world’s plants combined.

This makes soil both a ticking time bomb and an overlooked climate solution

“And because soil is such an important reservoir,” Berhe said, “a small change in the release of that carbon can lead to a big change in the concentrations of greenhouse gases in the atmosphere.”

A 2020 analysis in the journal Nature Sustainability found that better soil stewardship could reduce emissions by at least 5.5 gigatons of carbon dioxide each year — about 15 percent of current annual emissions.

“Once that happens,” Berhe said, “it’s not just the carbon status of the soil that’s improved. The soil literally becomes softer. It holds more water and nutrients. It’s easier for plants to grow in … and serve as a home for the most abundant and diverse group of organisms that we know of.

Enhancing carbon in soils is just the beginning. In 2017, an international team of scientists set out to determine how much carbon the planet could pull out of the atmosphere, if humans would only give it a chance. In a study in the Proceedings of the National Academy of Sciences (PNAS), they concluded natural climate systems are capable of storing almost 24 gigatons of carbon dioxide per year — roughly two thirds of what people emit.

About half of that sequestration would be cost-effective, meaning enacting the necessary protections would cost less than the consequences of keeping that carbon in the air.

Of the climate solutions they studied, few delivered more carbon bang per buck than mangroves — lush systems of salt-tolerant shrubs and trees that thrive where freshwater rivers spill into the sea. Though these forests occupy just 0.5 percent of the Earth’s shorelines, they account for 10 percent of the coast’s carbon storage capacity.

But the unique ecosystems are too often dismissed as unproductive swamps, good for no one but the mosquitoes. In the past half-century, more than a quarter of the world’s mangroves have been destroyed — drained for development, converted for shrimp farms, poisoned by fertilizer and drowned by dammed-up streams.

Yet the Earth cannot compensate for all of humanity’s pollution, said William Schlesinger, former dean of Duke University’s School of the Environment and a co-author on the 2017 PNAS study. Unless people also reduce the amount of greenhouse gases we emit, no amount of ecological restoration will save us.

“The bottom line is we’ve got to get off of using fossil fuels in transportation and heating and lighting and everything else,”

In public talks, he puts it this way: “It’s easier to patch a hole in a bag than to pick up the marbles that fall out.”

Since the end of the last ice age, the frozen expanse at the top of the world has acted as a protective shield. During the summer, when the sun shines 24 hours a day, Arctic sea ice reflects about two-thirds of the light that hits it back into space. By contrast, the dark open ocean absorbs the majority of the sun’s heat.

If the Arctic loses its perpetual ice cover, it would add half a degree Celsius of warming to the global average temperature, studies suggest. The world is hurtling toward that milestone. Since 1979, the volume of ice left at the end of the summer has shrunk about 75 percent.

There is just one way to save it, she said: by stopping global warming. Only by ending the use of fossil fuels and eliminating greenhouse gas emissions can people prevent the Arctic from heating further and give the ice a chance to recover.

If we do nothing, models indicate, it will be a matter of decades before the summertime Arctic is ice-free for the first time in human history. Sea levels will surge, coastal communities will be deluged, and we will no longer have the planet’s air conditioning unit to help us cool our world down.

Our species evolved and our civilization was built under fairly stable climate conditions. When things changed, they changed slowly, giving us time to adapt.

The rapid transformation of our planet doesn’t just endanger ecosystems; humanity will suffer. People have never lived on a planet without mangroves, or peatlands, or summertime ice. We’ve never had to go without the benefits the Earth provides.

humanity’s moral senses have not kept pace with this power

Empathy could be an emotional bulwark against a warming world, if our collective care produced collective action. But it evolved to respond to suffering right here, right now. Our empathic imagination is not naturally configured to stretch around the planet or toward future generations.

Empathy evolved as the north star to our moral compass. When someone else’s pain feels like our own, we have reason not to harm them. Empathy is also ancient, tuned to a time when we lived in small groups of hunter-gatherers. Much as we did back then, we still find it easier to care for people who look or think like us, who are familiar, and who are right in front of us.

hearing about hundreds or thousands of victims leaves us unmoved. Such “compassion collapse” stymies climate action.

Like distance, time diminishes empathy. People find the future psychologically fuzzy

we even tend to view our future selves as strangers. This leads individuals to make shortsighted choices such as accruing debt instead of saving for retirement

Across generations, this tunnel vision worsens. Not only are the consequences of our actions far off, but they will be experienced by strangers who have yet to be born.

Touching the past can connect us to the future, especially when we look back fondly. In one set of studies, psychologists induced people to think about the sacrifices past generations had made for them. These individuals became more willing to sacrifice short-term gains to help future generations, paying forward their forbears’ kindness

One strategy is to turn the abstract concrete. When people make personal (or even virtual) contact with individuals who differ from them, they see them more clearly and empathize with them more deeply.

even if empathy is naturally tuned to the short term, the right tools can expand it into the future and build climate consciousness along the way.

their effectiveness in the climate conversation might also reflect the moral urgency of coming face to face with the people who must live in the world we leave behind

As one child activist recently declared: “You’re all going to be dead in 2050. We’re not. You’re sealing our future now.”

This raises another challenge in caring for the future: We won’t be there. Considering great spans of time means facing our mortality — an unnerving encounter that can turn people inward and increase tribalism.

other experiences can make us feel entwined with the world after us. One is the feeling of awe: a sense of something so vast that it interrupts our selfish preoccupations. Psychologists induce awe by showing people images of enormous things, like the Milky Way or a vista of Himalayan peaks from the show “Planet Earth.” In one such study, after watching awe-inspiring clips vs. amusing ones, people reported feeling small but also more connected to others; they also acted more generously.

Consistent with this idea, psychologists have found that people with a long view of the past are more concerned with environmental sustainability. For instance, older countries score more favorably on an environmental performance index

People made to see the United States as an old country vs. a young one reported feeling closer to future generations and were more willing to donate to environmental organizations.

This might explain why children and teenagers, such as Swedish activist Greta Thunberg, have emerged as leaders in the movement for climate action: Children are living, tangible and beloved representatives of the future, not to blame for climate change but at risk of paying for it dearly.

Empathizing with the future, alone, will not save the planet. The majority of carbon emissions come from a tiny number of massive companies, which are abetted by government deregulation. Empathy can be a psychological force for good, but climate change is a structural problem.

That doesn’t mean individuals don’t matter. Our behaviors create norms, social movements and political pressure. Newfound awareness of how voiceless, powerless people suffer has sparked enormous change in the past. It can again.

Empathy is built on self-preservation. We watch out for our children because they carry our genes, for our tribe because it offers sex, safety and sustenance. Spreading our care across space and time runs counter to those ancient instincts. It’s difficult emotional work, and also necessary. We must try to evolve our emotional lives: away from the past and toward a future that needs us desperately. Doing so might help us to finally become the ancestors our descendants deserve.

Caring

“This is how wealthy individuals or corporations translate their economic power into political and cultural power,” he said. “They have their profits and they hire people to write books that say climate change is not real. They hear people to go on TV and say climate change is not real. It ends up that people without economic power don't have the same size voice as the people who have economic power, and so it ends up distorting democracy.

So it’s kind of a combination of both industry and conservative philanthropies that are funding this process, and what they did was they borrowed a great deal of the strategy and tactics that came out of the tobacco industry’s efforts to prevent action on the health impacts of smoking.

some of the same people and some of the same organizations that were involved in the tobacco issue are also involved in climate change.

The climate denial movement is a powerful political force, says Brulle. They've got to be, too, to outweigh in the public's mind the opinions of pretty much every relevant scientist

But to cause an extinction event on the scale of those seen millions of years ago, in which more than 75 percent of species disappeared, we would have to lose all our threatened species within a century and then keep losing species at that same super-high rate for between 240 and 540 more years. In other words, the concept assumes that we won’t save anything, ever, and that hundreds of years into the future, we will still be as inept at protecting biodiversity as we are now.

That’s just not true. As of today, according to the International Union for Conservation of Nature’s Red List, the conservation status of 128,918 species has been assessed. Of those, 902 have gone extinct since the year 1500. This is absolutely too many. One is too many.

this study actually looked at the average decline of a given population (not species) of wild animal. So severe declines in small populations disproportionately increase the average decline.

You might have also heard that we’ve lost something like 60 percent of wild animals since the 1970s? Surely this suggests that a lot more extinctions are imminent?

More recently, a new analysis of the data showed that, indeed, the 60 percent average decline was driven by very severe crashes in a very small number of vertebrate populations. For example, one small population of Australian waterfall frogs declined 99.5 percent over two years. This decline became one data point, which was averaged with 14,000 others, many from stable or increasing populations.

Really, less than 3 percent of vertebrate populations are crashing

This means that declines are not the rule everywhere. It means that the specific populations in crisis can be identified and helped. And we have the knowledge to save them, if we can marshal the will and resources.

This targeted approach works for environmental policy too. The Trump administration pushed for more than 100 rollbacks of pollution standards, land protections, and other green policies,

Jill Tauber, the vice president of litigation for climate and energy at Earthjustice, told me that her organization has more than 100 lawsuits pending against the Trump administration and that so far, once cases pass any procedural hurdles, her side is winning more than 80 percent of them

The U.S. could spend about what it already spends on energy—a mere 4 to 6 percent of gross domestic product—and still reach this goal, according to a new report out of Princeton University.

as the cost of key technologies such as solar panels and batteries has fallen, the price tag to move the country to net-zero emissions by 2050—as President Joe Biden has pledged—has also dropped

The necessary changes would have to start immediately, and they aren’t minor. Visualize a huge build-out of solar, wind, and transmission lines, for starters

What they need to be able to say clearly to politicians is: ‘I value this; this is an important priority to me.’

To make it happen, though, American citizens must “create a demand for the policy,”

On Wednesday, Biden signed an executive order on climate, which sets a goal of conserving at least 30 percent of the country by 2030, launches a Civilian Climate Corps, and hits pause on fossil-fuel development on public lands

“If we don’t keep up that demand for policy, then it is just not going to happen,”

Jenkins also rejects the idea that if we fail to keep warming under 1.5 degrees Celsius, the key target in an influential United Nations report, all is lost. “Any time you see a round number like 2.0 or 1.5 or 20 percent by 2020, that is a political number,” he said. “The reality is that every 10th of a degree matters.” There is no threshold after which it is not worth fighting.

climate change and extinction have been ongoing problems for as long as many of us can remember, feeling that they’re impossible to engage with right now is only natural.

But many of our problems are so thoroughly tangled up with one another that we may not need to fight them separately.

So fighting for racial or economic justice, or against voter suppression, still can mean fighting for the environment.

Not everything can be saved. But 2021 can be better than 2020, and 2031 can be much, much better than 2021, if we demand it.

U.S. government scientists announced that 2020 was one of the two hottest years in recorded history. The other hottest year was 2016: fittingly, the year that the United States elected Donald Trump president, a disaster for the environment as well as democratic norms

scientists sounding the alarm about high extinction rates, and in the years that followed, the idea that we are in the midst of one of the planet’s greatest mass-extinction events

One very good reason to feel overwhelmed is that everything seems screwed up at once.  As a country, we’re facing climate change, the pandemic, racial injustice, the threat of dangerous fascist elements

Environmental destruction disproportionately harms people of color and lower-income people. And people of color are, on average, significantly more concerned about climate change than white people. A leading cause of inaction on climate change is the hoarding of power by some of the world’s wealthiest people, who profit from planetary destruction that they don’t have to deal with personally. They can simply crank up the air conditioner, pay more for the last remaining champagne and oysters, or fly to their New Zealand bunker, so they have no incentive to change unsustainable systems that they benefit from. When political power is more fairly distributed, the environment will benefit.

The document also states that China and India, with large populations, will play key roles in determining how quickly global temperatures rise.

When it comes to the odds of countries around the world meeting the commitment made at the 2015 climate conference in Paris to keep the rise in global temperatures to less than 2 degrees Celsius, the intelligence report said the odds were not good.

“High-emitting countries would have to make rapid progress toward decarbonizing their energy systems by transitioning away from fossil fuels within the next decade, whereas developing countries would need to rely on low-carbon energy sources for their economic development.”

That report said the military would begin to spend a significant portion of its next budget on climate analysis in its national security exercises and analysis.

Its bases are vulnerable to flooding, fires, drought and rising sea levels. Flooding harmed the Navy Base Coronado during a particularly tough hurricane year, the Naval Air Station Key West was hit by severe drought several years ago and a wildfire in 2017 burned 380 acres on Vandenberg Air Force Base in Southern California, among myriad other examples.

Beyond harming its basic infrastructure, droughts, fires and flooding can harm the Pentagon’s the performance of its aircraft, the ability to do testing activities and a host of training exercises.

moving to directly integrate concept of climate change as a threat multiplier into all aspects of defense strategy, planning, force posture and budget,”

cited the growing United States rivalry with China as an example of why the two issues are linked. “The Pentagon must bring a climate lens to its strategic assessment of Chinese foreign policy and behavior on the world stage,” said Ms. Sikorsky, who is now director of the Center for Climate and Security. “Otherwise it will get answers to key questions about China’s strength and strategy wrong.”

The department said climate change’s effect on the Northwest Passage, the waters between the Atlantic and Pacific oceans and through the Arctic Ocean, are already apparent. With the ice melting, the area has become easier to navigate and has opened it up to competition with Russia and China.

ith deadly and destructive hurricanes driving migrants to leave their homes in Central America and flee to the United States through Mexico. This has overwhelmed border officials at times since 2014 and particularly during the last six months.

looking at how climate change is already pushing people around the world to migrate, both within countries and between them. The report notes one forecast suggesting that climate change could lead to almost three percent of the populations of Latin America, South Asia and sub-Saharan Africa moving within their countries by 2050 — more than 143 million people.

“Even in the United States, one extreme event can result in a relatively high degree of permanent relocation of low-income populations exposed to chronic and worsening conditions over time,” the report says.

The Bloomberg article cites a July meta-analysis in the medical journal Lancet, which found a tenuous link between higher temperatures and suicides and mental illness. But the study deems the collective evidence of “low certainty” owing to inconsistent study findings, methodologies, measured variables and definitions.

“climate change might not necessarily increase mental health issues because people might adapt over time, meaning that higher temperatures could become normal and not be experienced as anomalous or extreme.”

yes. Before the media began reporting on putative temperature records—the scientific evidence for which is also weak—heat waves were treated as a normal part of summer. Uncomfortable, but figuratively nothing to sweat about.

according to a World Health Organization report last year, the very “awareness of climate change and extreme weather events and their impacts” may lead to a host of ills, including strained social relationships, anxiety, depression, intimate-partner violence, helplessness, suicidal behavior and alcohol and substance abuse.

A study in 2021 of 16- to 25-year-olds in 10 countries including the U.S. reported that 59% were very or extremely worried about climate change, and 84% were at least moderately worried

Forty-five percent claimed they were so worried that they struggled to function on a daily basis, the definition of an anxiety disorder.

“First and foremost, it is imperative that adults understand that youth climate anxiety (also referred to as eco-anxiety, solastalgia, eco-guilt or ecological grief) is an emotionally and cognitively functional response to real existential threats,” a May 10 editorial in the journal Nature explained. “Although feelings of powerlessness, grief and fear can be profoundly disruptive—particularly for young people unaccustomed to the depth and complexity of such feelings—it is important to acknowledge that this response is a rational one.”

These anxieties are no more rational than the threats from climate change are existential.

A more apt term for such fear is climate hypochondria.

The New Yorker magazine earlier this month published a 4,400-word piece titled “What to Do With Climate Emotions” by Jia Tolentino, a woman in the throes of such neurosis

Ms. Tolentino goes on to describe how climate therapists can help patients cope. “The goal is not to resolve the intrusive feeling and put it away” but, as one therapist advises her, “to aim for a middle ground of sustainable distress.” Even the climate left’s despair must be “sustainable.”

there’s nothing normal about climate anxiety, despite the left’s claims to the contrary.

Progressives may even use climate change to displace their other anxieties—for instance, about having children

Displacement is a maladaptive mechanism by which people redirect negative emotions from one thing to another

Climate hypochondriacs deserve to be treated with compassion, much like anyone who suffers from mental illness. They shouldn’t, however, expect everyone else to enable their neuroses.

In the ’90s, when Ericsson looked into the numbers for the two dozen or so clinics that use his process, he discovered, to his surprise, that couples were requesting more girls than boys, a gap that has persisted, even though Ericsson advertises the method as more effective for producing boys. In some clinics, Ericsson has said, the ratio is now as high as 2 to 1.

A newer method for sperm selection, called MicroSort, is currently completing Food and Drug Administration clinical trials. The girl requests for that method run at about 75 percent.

Even more unsettling for Ericsson, it has become clear that in choosing the sex of the next generation, he is no longer the boss. “It’s the women who are driving all the decisions,”

Now the centuries-old preference for sons is eroding—or even reversing. “Women of our generation want daughters precisely because we like who we are,”

what if equality isn’t the end point? What if modern, postindustrial society is simply better suited to women?

Even Ericsson, the stubborn old goat, can sigh and mark the passing of an era. “Did male dominance exist? Of course it existed. But it seems to be gone now. And the era of the firstborn son is totally gone.”

Ericsson’s extended family is as good an illustration of the rapidly shifting landscape as any other. His 26-year-old granddaughter—“tall, slender, brighter than hell, with a take-no-prisoners personality”—is a biochemist and works on genetic sequencing. His niece studied civil engineering at the University of Southern California. His grandsons, he says, are bright and handsome, but in school “their eyes glaze over. I have to tell ’em: ‘Just don’t screw up and crash your pickup truck and get some girl pregnant and ruin your life.’

Man has been the dominant sex since, well, the dawn of mankind. But for the first time in human history, that is changing—and with shocking speed. Cultural and economic changes always reinforce each other

And the global economy is evolving in a way that is eroding the historical preference for male children, worldwide

Over several centuries, South Korea, for instance, constructed one of the most rigid patriarchal societies in the world.

As recently as 1985, about half of all women in a national survey said they “must have a son.” That percentage fell slowly until 1991 and then plummeted to just over 15 percent by 2003. Male preference in South Korea “is over,” says Monica Das Gupta, a demographer and Asia expert at the World Bank. “It happened so fast. It’s hard to believe it, but it is.” The same shift is now beginning in other rapidly industrializing countries such as India and China.

As thinking and communicating have come to eclipse physical strength and stamina as the keys to economic success, those societies that take advantage of the talents of all their adults, not just half of them, have pulled away from the rest. And because geopolitics and global culture are, ultimately, Darwinian, other societies either follow suit or end up marginalized

None of the 30 or so men sitting in a classroom at a downtown Kansas City school have come for voluntary adult enrichment. Having failed to pay their child support, they were given the choice by a judge to go to jail or attend a weekly class on fathering, which to them seemed the better deal.

in the U.S., the world’s most advanced economy, something much more remarkable seems to be happening. American parents are beginning to choose to have girls over boys. As they imagine the pride of watching a child grow and develop and succeed as an adult, it is more often a girl that they see in their mind’s eye.

What if the modern, postindustrial economy is simply more congenial to women than to men?

what if men and women were fulfilling not biological imperatives but social roles, based on what was more efficient throughout a long era of human history? What if that era has now come to an end? More to the point, what if the economics of the new era are better suited to women?

Once you open your eyes to this possibility, the evidence is all around you. It can be found, most immediately, in the wreckage of the Great Recession, in which three-quarters of the 8 million jobs lost were lost by men.

The recession merely revealed—and accelerated—a profound economic shift that has been going on for at least 30 years

Earlier this year, for the first time in American history, the balance of the workforce tipped toward women, who now hold a majority of the nation’s job

With few exceptions, the greater the power of women, the greater the country’s economic success

Women dominate today’s colleges and professional schools—for every two men who will receive a B.A. this year, three women will do the same. Of the 15 job categories projected to grow the most in the next decade in the U.S., all but two are occupied primarily by women

Indeed, the U.S. economy is in some ways becoming a kind of traveling sisterhood: upper-class women leave home and enter the workforce, creating domestic jobs for other women to fill.

The postindustrial economy is indifferent to men’s size and strength. The attributes that are most valuable today—social intelligence, open communication, the ability to sit still and focus—are, at a minimum, not predominantly male. In fact, the opposite may be true

Yes, women still do most of the child care. And yes, the upper reaches of society are still dominated by men. But given the power of the forces pushing at the economy, this setup feels like the last gasp of a dying age rather than the permanent establishment

In his final book, The Bachelors’ Ball, published in 2007, the sociologist Pierre Bourdieu describes the changing gender dynamics of Béarn, the region in southwestern France where he grew up. The eldest sons once held the privileges of patrimonial loyalty and filial inheritance in Béarn. But over the decades, changing economic forces turned those privileges into curses. Although the land no longer produced the impressive income it once had, the men felt obligated to tend it. Meanwhile, modern women shunned farm life, lured away by jobs and adventure in the city

The role reversal that’s under way between American men and women shows up most obviously and painfully in the working class

The working class, which has long defined our notions of masculinity, is slowly turning into a matriarchy, with men increasingly absent from the home and women making all the decisions

“Let’s see,” he continues, reading from a worksheet. What are the four kinds of paternal authority? Moral, emotional, social, and physical. “But you ain’t none of those in that house. All you are is a paycheck, and now you ain’t even that. And if you try to exercise your authority, she’ll call 911. How does that make you feel? You’re supposed to be the authority, and she says, ‘Get out of the house, bitch.’ She’s calling you ‘bitch’!”

Just about the only professions in which women still make up a relatively small minority of newly minted workers are engineering and those calling on a hard-science background, and even in those areas, women have made strong gains since the 1970s.

“Who’s doing what?” he asks them. “What is our role? Everyone’s telling us we’re supposed to be the head of a nuclear family, so you feel like you got robbed. It’s toxic, and poisonous, and it’s setting us up for failure.” He writes on the board: $85,000. “This is her salary.” Then: $12,000. “This is your salary. Who’s the damn man? Who’s the man now?” A murmur rises. “That’s right. She’s the man.”

In 1950, roughly one in 20 men of prime working age, like Henderson, was not working; today that ratio is about one in five, the highest ever recorded.

Men dominate just two of the 15 job categories projected to grow the most over the next decade: janitor and computer engineer. Women have everything else—nursing, home health assistance, child care, food preparation

Many of the new jobs, says Heather Boushey of the Center for American Progress, “replace the things that women used to do in the home for free.” None is especially high-paying. But the steady accumulation of these jobs adds up to an economy that, for the working class, has become more amenable to women than to men.

The list of growing jobs is heavy on nurturing professions, in which women, ironically, seem to benefit from old stereotypes and habits.

The men in that room, almost without exception, were casualties of the end of the manufacturing era. Most of them had continued to work with their hands even as demand for manual labor was declining.

Many professions that started out as the province of men are now filled mostly with women—secretary and teacher come to mind. Yet I’m not aware of any that have gone the opposite way. Nursing schools have tried hard to recruit men in the past few years, with minimal success. Teaching schools, eager to recruit male role models, are having a similarly hard time

The range of acceptable masculine roles has changed comparatively little, and has perhaps even narrowed as men have shied away from some careers women have entered. As Jessica Grose wrote in Slate, men seem “fixed in cultural aspic.” And with each passing day, they lag further behind.

women are also starting to dominate middle management, and a surprising number of professional careers as well. According to the Bureau of Labor Statistics, women now hold 51.4 percent of managerial and professional jobs—up from 26.1 percent in 1980

About a third of America’s physicians are now women, as are 45 percent of associates in law firms—and both those percentages are rising fast.

When we look back on this period, argues Jamie Ladge, a business professor at Northeastern University, we will see it as a “turning point for women in the workforce.”

A white-collar economy values raw intellectual horsepower, which men and women have in equal amounts. It also requires communication skills and social intelligence, areas in which women, according to many studies, have a slight edge. Perhaps most important—for better or worse—it increasingly requires formal education credentials, which women are more prone to acquire,

The men are black and white, their ages ranging from about 20 to 40. A couple look like they might have spent a night or two on the streets, but the rest look like they work, or used to. Now they have put down their sodas, and El-Scari has their attention, so he gets a little more philosophical

Companies began moving out of the city in search not only of lower rent but also of the “best educated, most conscientious, most stable workers.” They found their brightest prospects among “underemployed females living in middle-class communities on the fringe of the old urban areas.” As Garreau chronicles the rise of suburban office parks, he places special emphasis on 1978, the peak year for women entering the workforce. When brawn was off the list of job requirements, women often measured up better than men. They were smart, dutiful, and, as long as employers could make the jobs more convenient for them, more reliable

Near the top of the jobs pyramid, of course, the upward march of women stalls. Prominent female CEOs, past and present, are so rare that they count as minor celebrities,

Only 3 percent of Fortune 500 CEOs are women, and the number has never risen much above that.

What are these talents? Once it was thought that leaders should be aggressive and competitive, and that men are naturally more of both. But psychological research has complicated this picture. In lab studies that simulate negotiations, men and women are just about equally assertive and competitive, with slight variations. Men tend to assert themselves in a controlling manner, while women tend to take into account the rights of others, but both styles are equally effective,

Researchers have started looking into the relationship between testosterone and excessive risk, and wondering if groups of men, in some basic hormonal way, spur each other to make reckless decisions. The picture emerging is a mirror image of the traditional gender map: men and markets on the side of the irrational and overemotional, and women on the side of the cool and levelheaded.

the perception of the ideal business leader is starting to shift. The old model of command and control, with one leader holding all the decision-making power, is considered hidebound. The new model is sometimes called “post-heroic,” or “transformational”

he aim is to behave like a good coach, and channel your charisma to motivate others to be hardworking and creative. The model is not explicitly defined as feminist, but it echoes literature about male-female differences

Most important, women earn almost 60 percent of all bachelor’s degrees—the minimum requirement, in most cases, for an affluent life.

Firms that had women in top positions performed better, and this was especially true if the firm pursued what the researchers called an “innovation intensive strategy,” in which, they argued, “creativity and collaboration may be especially important”

he association is clear: innovative, successful firms are the ones that promote women. The same Columbia-Maryland study ranked America’s industries by the proportion of firms that employed female executives, and the bottom of the list reads like the ghosts of the economy past: shipbuilding, real estate, coal, steelworks, machinery.

To see the future—of the workforce, the economy, and the culture—you need to spend some time at America’s colleges and professional schools

emographically, we can see with absolute clarity that in the coming decades the middle class will be dominated by women.

Women now earn 60 percent of master’s degrees, about half of all law and medical degrees, and 42 percent of all M.B.A.s

“We never explicitly say, ‘Develop your feminine side,’ but it’s clear that’s what we’re advocating,” s

n a stark reversal since the 1970s, men are now more likely than women to hold only a high-school diploma.

ne would think that if men were acting in a rational way, they would be getting the education they need to get along out there,” says Tom Mortenson, a senior scholar at the Pell Institute for the Study of Opportunity in Higher Education. “But they are just failing to adapt.”

I visited a few schools around Kansas City to get a feel for the gender dynamics of higher education. I started at the downtown campus of Metropolitan Community College. Metropolitan is the kind of place where people go to learn practical job skills and keep current with the changing economy, and as in most community colleges these days, men were conspicuously absent.

the tidal wave of women continues to wash through the school—they now make up about 70 percent of its students. They come to train to be nurses and teachers

As for the men? Well, little has changed. “I recall one guy who was really smart,” one of the school’s counselors told me. “But he was reading at a sixth-grade level and felt embarrassed in front of the women. He had to hide his books from his friends, who would tease him when he studied. Then came the excuses. ‘It’s spring, gotta play ball.’ ‘It’s winter, too cold.’ He didn’t make it.”

“The economy isn’t as friendly to men as it once was,” says Jacqueline King, of the American Council on Education. “You would think men and women would go to these colleges at the same rate.” But they don’t.

Men, it turned out, had a harder time committing to school, even when they desperately needed to retool. They tended to start out behind academically, and many felt intimidated by the schoolwork. They reported feeling isolated and were much worse at seeking out fellow students, study groups, or counselors to help them adjust.

Mothers going back to school described themselves as good role models for their children. Fathers worried that they were abrogating their responsibilities as breadwinner.

it began showing up not just in community and liberal-arts colleges but in the flagship public universities—the UCs and the SUNYs and the UNCs.

Guys high-five each other when they get a C, while girls beat themselves up over a B-minus. Guys play video games in each other’s rooms, while girls crowd the study hall. Girls get their degrees with no drama, while guys seem always in danger of drifting away.

realized how much the basic expectations for men and women had shifted. Many of the women’s mothers had established their careers later in life, sometimes after a divorce, and they had urged their daughters to get to their own careers more quickly. They would be a campus of Tracy Flicks, except that they seemed neither especially brittle nor secretly falling apart.

Among traditional college students from the highest-income families, the gender gap pretty much disappears. But the story is not so simple. Wealthier students tend to go to elite private schools, and elite private schools live by their own rules.

Quietly, they’ve been opening up a new frontier in affirmative action, with boys playing the role of the underprivileged applicants needing an extra boost

among selective liberal-arts schools, being male raises the chance of college acceptance by 6.5 to 9 percentage points

the U.S. Commission on Civil Rights has voted to investigate what some academics have described as the “open secret” that private schools “are discriminating in admissions in order to maintain what they regard as an appropriate gender balance.”

To avoid crossing the dreaded 60 percent threshold, admissions officers have created a language to explain away the boys’ deficits: “Brain hasn’t kicked in yet.” “Slow to cook.” “Hasn’t quite peaked.” “Holistic picture.”

Clearly, some percentage of boys are just temperamentally unsuited to college, at least at age 18 or 20, but without it, they have a harder time finding their place these days

“Forty years ago, 30 years ago, if you were one of the fairly constant fraction of boys who wasn’t ready to learn in high school, there were ways for you to enter the mainstream economy,” says Henry Farber, an economist at Princeton. “When you woke up, there were jobs. There were good industrial jobs, so you could have a good industrial, blue-collar career. Now those jobs are gone.”

the disparities start before college. Throughout the ’90s, various authors and researchers agonized over why boys seemed to be failing at every level of education, from elementary school on up

identified various culprits: a misguided feminism that treated normal boys as incipient harassers (Christina Hoff Sommers); different brain chemistry (Michael Gurian); a demanding, verbally focused curriculum that ignored boys’ interests (Richard Whitmire)

t’s not all that clear that boys have become more dysfunctional—or have changed in any way. What’s clear is that schools, like the economy, now value the self-control, focus, and verbal aptitude that seem to come more easily to young girls.

movement is growing for more all-boys schools and classes, and for respecting the individual learning styles of boys

In their desperation to reach out to boys, some colleges have formed football teams and started engineering programs.

allowing generations of boys to grow up feeling rootless and obsolete is not a recipe for a peaceful future. Men have few natural support groups and little access to social welfare; the men’s-rights groups that do exist in the U.S. are taking on an angry, antiwoman edge.

Marriages fall apart or never happen at all, and children are raised with no fathers. Far from being celebrated, women’s rising power is perceived as a threat.

his is the first time that the cohort of Americans ages 30 to 44 has more college-educated women than college-educated men, and the effects are upsetting the traditional Cleaver-family dynamics. In 1970, women contributed 2 to 6 percent of the family income. Now the typical working wife brings home 42.2 percent, and four in 10 mothers—many of them single mothers—are the primary breadwinners in their familie

ncreasing numbers of women—unable to find men with a similar income and education—are forgoing marriage altogether. In 1970, 84 percent of women ages 30 to 44 were married; now 60 percent are.

or all the hand-wringing over the lonely spinster, the real loser in society—the only one to have made just slight financial gains since the 1970s—is the single man, whether poor or rich, college-educated or not. Hens rejoice; it’s the bachelor party that’s over.

The sociologist Kathryn Edin spent five years talking with low-income mothers in the inner suburbs of Philadelphia. Many of these neighborhoods, she found, had turned into matriarchies, with women making all the decisions and dictating what the men should and should not do. “I think something feminists have missed,” Edin told me, “is how much power women have” when they’re not bound by marriage

he women, she explained, “make every important decision”—whether to have a baby, how to raise it, where to live. “It’s definitely ‘my way or the highway,’

Thirty years ago, cultural norms were such that the fathers might have said, ‘Great, catch me if you can.’ Now they are desperate to father, but they are pessimistic about whether they can meet her expectations.” The women don’t want them as husbands, and they have no steady income to provide. So what do they have?

Nothing,” Edin says. “They have nothing. The men were just annihilated in the recession of the ’90s, and things never got better. Now it’s just awful.”

The phenomenon of children being born to unmarried parents “has spread to barrios and trailer parks and rural areas and small towns,” Edin says, and it is creeping up the class ladder. After staying steady for a while, the portion of American children born to unmarried parents jumped to 40 percent in the past few years.

Many of their mothers are struggling financially; the most successful are working and going to school and hustling to feed the children, and then falling asleep in the elevator of the community college.

Still, they are in charge. “The family changes over the past four decades have been bad for men and bad for kids, but it’s not clear they are bad for women,”

Over the years, researchers have proposed different theories to explain the erosion of marriage in the lower classes: the rise of welfare, or the disappearance of work and thus of marriageable men

the most compelling theory is that marriage has disappeared because women are setting the terms—and setting them too high for the men around them to reach.

The whole country’s future could look much as the present does for many lower-class African Americans: the mothers pull themselves up, but the men don’t follow. First-generation college-educated white women may join their black counterparts in a new kind of middle class, where marriage is increasingly rare.

Japan is in a national panic over the rise of the “herbivores,” the cohort of young men who are rejecting the hard-drinking salaryman life of their fathers and are instead gardening, organizing dessert parties, acting cartoonishly feminine, and declining to have sex. The generational young-women counterparts are known in Japan as the “carnivores,” or sometimes the “hunters.”

American pop culture keeps producing endless variations on the omega male, who ranks even below the beta in the wolf pack.

At the same time, a new kind of alpha female has appeared, stirring up anxiety and, occasionally, fear. The cougar trope started out as a joke about desperate older women. Now it’s gone mainstream, even in Hollywood,

the more women dominate, the more they behave, fittingly, like the dominant sex. Rates of violence committed by middle-aged women have skyrocketed since the 1980

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.”

However, there is widespread skepticism about the prospect for change. In eight of the 17 publics, roughly half or more of those polled say the political system needs major changes or a complete overhaul and say they have little or no confidence the system can be changed effectively.

We found that the strongest predictor of being dissatisfied was being unhappy with the current state of the national economy. Another significant predictor was how someone feels about economic opportunity.

dissatisfaction with the way democracy is working was much more common among people who expect that when children in their country today grow up, they will be worse off financially than their parents. The economic pessimists are also especially likely to think their country’s political system needs major changes or needs to be completely reformed. For example, in the United Kingdom, 61% of respondents who are pessimistic about the next generation’s financial prospects think their country needs significant political reform, compared with just 34% among those who are optimistic that the next generation will do better financially than their parents.

People who believe their country is doing a poor job of dealing with the pandemic are consistently more likely to say they are dissatisfied with the way their democracy is working and that they want significant changes to the political system. For instance, 73% of Germans who feel their country is handling the crisis poorly say they believe their political system needs major changes or should be completely overhauled, while just 32% of those who think the country is handling it well express this view.

Across 27 nations we polled in 2018, a median of 54% said that most politicians in their country are corrupt. This sentiment was especially high in Greece (89%) and Russia (82%). When we asked Americans a similar question in the fall of 2020, two-thirds said most politicians are corrupt.

A median of 78% across the 38 nations polled said that “a democratic system where representatives elected by citizens decide what becomes law” is a very or somewhat good way to govern their country. More than half expressed this view in every country polled. However, even at this broad level, enthusiasm for representative democracy was somewhat subdued – a median of only 33% said it is a very good approach to governing.

Across the 16 advanced economies surveyed, a median of just 17% consider American democracy a good model for other countries to follow. A median of 57% think it used to be a good example but has not been in recent years. And around a quarter say the U.S. has never been a good example. The belief that democracy in the U.S. has never been a good model for other nations is especially common among young adults.

For example, a median of 49% believed a system in which “experts, not elected officials, make decisions according to what they think is best for the country” would be very or somewhat good. 

A median of 26% considered “a system in which a strong leader can make decisions without interference from parliament or the courts” a very or somewhat good way to govern.

A median of 24% said “a system in which the military rules the country” would be a very or somewhat good system. In five countries – Vietnam, Indonesia, India, South Africa and Nigeria – roughly half or more expressed this opinion, as did at least 40% in another six nations. And higher-income nations weren’t completely immune: 17% in the United States, Italy and France believed military rule could be a good way to run the country.

For example, 27% of Americans who identified as conservative thought autocracy would be a good way to govern, compared with 14% who identified as liberal. And 20% of conservatives supported military rule, compared with 12% of liberals. People with lower levels of educational attainment were more likely to consider military rule a good way to govern in 23 countries.

A median of more than 67% across 34 countries rated a fair judicial system, gender equality and freedom of religion as very important. But there was less support for holding regular competitive elections, freedom of speech and press freedom. A median of roughly six-in-ten or fewer said it was very important to have free expression on the internet or to allow human rights groups and opposition parties to operate freely.

In Greece, for example, the share who say having people of many different racial, ethnic and religious backgrounds makes their country a better place to live more than doubled between 2017 and 2021. Over the same period, favorable views of diversity increased by about 10 percentage points or more in Japan, the Netherlands, the UK and Spain. Slightly smaller increases can be seen in Germany, South Korea, Australia and Sweden.

A median of 67% across the same 17 publics say racial or ethnic discrimination is a problem where they live. Roughly three-in-ten or more in Germany, Spain, the UK, Greece, France, the U.S. and Italy say it is a very serious problem in their country. Younger adults and those on the ideological left are often more convinced on this point. In the U.S., about two-thirds of Americans on the left say racial and ethnic discrimination is a very serious problem in their country, compared with only 19% of Americans on the political right.

median of 56% across 17 advanced economies surveyed in 2021 say their political system needs major changes or needs to be completely reformed. Roughly two-thirds or more express this opinion in Italy, Spain, the U.S., South Korea, Greece, France, Belgium and Japan.

Across the 17 advanced economies we surveyed in 2021, a median of 61% say their country is more divided than before the outbreak. Moreover, the share of the public that feels this way has risen substantially as the pandemic has worn on. In the spring of 2020, only months into the crisis, just 29% of Canadians believed they were more divided, but a year later 61% express this view.

a median of 64% disagreed with the statement “most elected officials care what people like me think.”

A median of 50% disagreed with the statement “the state is run for the benefit of all the people,” while 49% agreed.

For example, 88% of Italians in 2002 said their government was run for the benefit of all, but only 30% held this view in 2019.

Across 34 nations polled in 2019, a median of 67% agreed that voting gives ordinary people some say about how the government runs things.

For climate, we already are seeing a glimpse of what is to come: drought, floods and far more extreme storms than in the recent past. We saw some of the implications over the past year, with supply chains broken because rivers were too dry for shipping and hydroelectric and nuclear power impaired.

As with climate change, demographic shifts determine societal ones, like straining the social contract between the working and the aged.

We are reversing the globalization of the past 40 years, with the links in our geopolitical and economic network fraying. “Friendshoring,” or moving production to friendly countries, is a new term. The geopolitical forces behind deglobalization will amplify the stresses from climate change and demographics to lead to a frenzied competition for resources and consumers.

The problem here, and a problem broadly with complex and dynamic systems, is that the whole doesn’t look like the sum of the parts. If you have a lot of people running around, the overall picture can look different than what any one of those people is doing. Maybe in aggregate their actions jam the doorway; maybe in aggregate they create a stampede

if we can’t get a firm hold on pedestrian economic issues like inflation and recession — the prospects are not bright for getting our forecasts right for these existential forces.

The problem is that the models don’t work when our economy is weird. And that’s precisely when we most need them to work.

Economics failed with the 2008 crisis because economic theory has established that it cannot predict such crises.

A key reason these models fail in times of crisis is that they can’t deal with a world filled with complexity or with surprising twists and turns.

The fourth, artificial intelligence, is a wild card. But we already are seeing risks for work and privacy, and for frightening advances in warfare.

we are not a mechanical system. We are humans who innovate, change with our experiences, and at times game the system

Reflecting on the 1987 market crash, the brilliant physicist Richard Feynman remarked on the difficulty facing economists by noting that subatomic particles don’t act based on what they think other subatomic particles are planning — but people do that.

What if economists can’t turn things around? This is a possibility because we are walking into a world unlike any we have seen. We can’t anticipate all the ways climate change might affect us or where our creativity will take us with A.I. Which brings us to what is called radical uncertainty, where we simply have no clue — where we are caught unaware by things we haven’t even thought of.

This possibility is not much on the minds of economists

How do we deal with risks we cannot even define? A good start is to move away from the economist’s palette of efficiency and rationality and instead look at examples of survival in worlds of radical uncertainty.

In our time savannas are turning to deserts. The alternative to the economist’s model is to take a coarse approach, to be more adaptable — leave some short-term fine tuning and optimization by the wayside

Our long term might look brighter if we act like cockroaches. An insect fine tuned for a jungle may dominate the cockroach in that environment. But once the world changes and the jungle disappears, it will as well.

But while those are huge numbers by any measure (world GDP is around $100 trillion), they aren’t big enough to motivate most leaders to justify mitigation, which will also cost a whole lot of money.

To put it in terms the authors use, the recently enacted Inflation Reduction Act will cost Americans roughly $80 per ton of carbon emissions avoided, and while each ton not pumped into the atmosphere would save the world $200 as a whole, it would only save Americans about $40 of that $200, making it feel to some altruistic but not self-evident in purely economic terms.

In their new paper, economists Adrien Bilal of Harvard and Diego Känzig of Northwestern take a fresh look at the data

They show that the social cost of carbon is likely far bigger — six times bigger — than previously estimated: losses of more than $1,000 per ton, or around 12 percent of world GDP per degree of warming.

— roughly equivalent to the economic drag on big economies if they were permanently at war.

Suddenly, that $80 Americans are spending on reducing one ton of carbon emissions is netting them $200 or so in U.S. economic activity.

Bilal and Känzig argue that it’s very much worth it for countries of means to spend the money now to avoid much greater costs down the line

the potential losses are so vast it makes sense for these countries to go ahead and act on their own to avoid climate change losses, even if other nations do nothing.

What’s different about your methodology and how did it lead you to the numbers you've come up with?

Adrien Bilal: So virtually all of the previous work that's been done on the subject has relied on comparisons of different countries that heat up or cool down at different points in time. The U.K. gets a little hotter in one year, and then Germany stays cool. And then you look at how GDP in the U.K. evolves following that change in temperature.

that generally gives you numbers in the vicinity of $150 per ton of carbon emitted and a 2 percent decline in GDP per degree Celsius in warming

we think that is quite different from what climate change is actually doing to the world. It's not only that the U.K. is going to heat up a little more than Germany, but the whole world is heating up because of climate change. And, in particular, oceans are also heating up. And when the whole planet warms, that has potentially really different implications for the climate system, increased frequency of extreme weather events that then have big local impacts. 

that's actually what geoscientists have been telling us for a long time, but it simply hadn't percolated into economics. And so we took that perspective very seriously and thought, "Well, what happens when we basically compare years where the world is very hot to years where the world is cooler?" And that gives you a much larger effect of climate change on the economy.

At the moment, reactionary forces have a death grip on the Republican Party, and their power has been cemented by the party’s institutionalization of closed primaries and caucuses (neither independents nor Democrats can participate) in more than half the states.

If the conservative movement continues on its downward trajectory, the American business community, which has the most to lose from Republican failure, will be the key force arguing for moderation.The problem that faces business leaders pressing for reform is not just the normal reluctance of a political party to change. Instead, it is the fact that much of the Republican electorate, as presently constructed, is profoundly committed — morally and ideologically — to “traditional values.” You’re asking groups of people to change who were brought together by their resistance to change. Their opposition to change is why they are Republicans

An indirect but important reflection of partisan attitudes to change is visible in the higher percentage of Republicans, 58 percent, who believe in creationism – defined in this survey as the belief that God created human beings in their present form within the last 10,000 years – than Democrats, 41 percent, and independents, 39 percent.In effect, for many cultural and social conservatives, being a Republican is not just an allegiance to one of two major political parties but a deeply held belief system, an ideology with a strong religious core.

Bush also destroyed centrist Democrats intellectually, by making it impossible for them to credibly critique liberalism from the right.

. In the late ’80s and the ’90s, centrist Democrats had also argued that Reagan’s decision to boost defense spending and aid the Afghan mujahideen had helped topple the Soviet empire. But in 2003, when Bush invaded Iraq, he sparked the greatest foreign-policy catastrophe since Vietnam.

If the lesson of the Reagan era had been that Democrats should give a Republican president his due, the lesson of the Bush era was that doing so brought disaster.

In the Senate, Bush’s 2001 tax cut passed with 12 Democratic votes; the Iraq War was authorized with 29. As the calamitous consequences of these votes became clear, the revolt against them destroyed the Democratic Party’s centrist wing

With the Dean campaign came an intellectual revolution inside the Democratic Party. His insurgency helped propel Daily Kos, a group blog dedicated to stiffening the liberal spine. It energized the progressive activist group MoveOn. It also coincided with Paul Krugman’s emergence as America’s most influential liberal columnist and Jon Stewart’s emergence as America’s most influential liberal television personality.

All of this has shaped the Clinton campaign’s response to Sanders. At the first Democratic debate, she noted that, unlike him, she favors “rein[ing] in the excesses of capitalism” rather than abandoning it altogether. But the only specific policy difference she highlighted was gun control, on which she attacked him from the left.

Whereas the party’s most respected thinkers had once urged Democrats to critique liberal orthodoxy, they now criticized Democrats for not defending that orthodoxy fiercely enough. The presidency of George W. Bush had made Democrats unapologetically liberal, and the presidency of Barack Obama was the most tangible result.

that’s only half the story. Because if George W. Bush’s failures pushed the Democratic Party to the left, Barack Obama’s have pushed it even further. If Bush was responsible for the liberal infrastructure that helped elect Obama, Obama has now inadvertently contributed to the creation of two movements—Occupy and Black Lives Matter—dedicated to the proposition that even the liberalism he espouses is not left-wing enough.

Todd Gitlin quotes Jeremy Varon, a close observer of Occupy who teaches at the New School for Social Research, as saying, “This is the Obama generation declaring their independence from his administration. We thought his voice was ours. Now we know we have to speak for ourselves.

Occupy. The movement may have burned out, but it injected economic inequality into the American political debate

The same anger that sparked Occupy—directed not merely at Wall Street but at the Democratic Party elites who coddled it—fueled Bill de Blasio’s election and Elizabeth Warren’s rise to national prominence. And without Occupy, it’s impossible to understand why a curmudgeonly Democratic Socialist from Vermont is seriously challenging Hillary Clinton

the Democracy Alliance, the party’s most influential donor club, which includes mega-funders such as George Soros and Tom Steyer, has itself shifted leftward during the Obama years. In 2014, it gave Warren a rapturous welcome when she spoke at the group’s annual winter meeting. Last spring it announced that it was making economic inequality its top priority.

By the time Barack Obama defeated Hillary Clinton for the Democratic presidential nomination in 2008, in part because of her support for the Iraq War, the mood inside the party had fundamentally changed.

Moreover, the Occupy-Warren-Sanders axis has influenced Clinton’s own economic agenda, which is significantly further left than the one she ran on in 2008. She has called for tougher regulation of the financial industry, mused about raising Social Security taxes on the wealthy (something she opposed in 2008), and criticized the Trans-Pacific Partnership (a trade agreement she once gushed about).

“Black Lives Matter developed in the wake of the failure of the Obama administration,” argues the Cornell sociologist Travis Gosa, a co-editor of The Hip Hop & Obama Reader. “Black Lives Matter is the voice of a Millennial generation that’s been sold a ba

Had Black Lives Matter existed when Bill Clinton was seeking the presidency, he probably would have run against the group

Today, by contrast, the Democratic Establishment has responded to Black Lives Matter much as it responded to Occupy: with applause

what’s most remarkable isn’t Hillary Clinton’s move to the left, or the Democratic Party’s. It’s the American public’s willingness to go along.

Much of this shift is being driven by a changing mood among whites. Between January and April alone, according to a YouGov poll, the percentage of whites who called deaths like those of Michael Brown and Freddie Gray “isolated incident[s]” dropped 20 points. There’s even been movement within the GOP. From 2014 to 2015, the percentage of Republicans saying America needs to make changes to give blacks an equal chance rose 15 points—more than the percentage increase among Democrats or Independents.

Most interesting—because he is the Republican candidate with the keenest sense of how to appeal to the general electorate—has been the approach of Senator Marco Rubio. In August, a Fox News anchor asked him about Black Lives Matter. Instead of condemning the movement, Rubio told the story of an African American friend of his whom police had stopped eight or nine times over the previous 18 months even though he had never broken the law. “This is a problem our nation has to confront,” Rubio declared. Then he talked about young African Americans who get arrested for nonviolent offenses and pushed into plea deals by overworked public defenders. The government, he said, must “look for ways to divert people” from going to jail “so that you don’t get people stigmatized early in life.”

Conservative Republicans didn’t talk this way in the ’90s. They didn’t talk this way even in the early Obama years. The fact that Rubio does so now is more evidence that today, unlike in the mid-’60s, the debate about race and justice isn’t moving to the right. It’s moving further left

What’s different this time? One difference is that in the 1960s and ’70s, crime exploded, fueling a politics of fear and vengeance. Over the past two decades, by contrast, crime has plummeted. And despite some hyperbolic headlines, there’s no clear evidence that it’s rising significantly again.

When the Williams Institute at the UCLA School of Law examined polls, it found that between two-thirds and three-quarters of Americans now support barring discrimination against transgender people.

Most Americans, in other words, having decided that discriminating against lesbians and gay men was wrong, have simply extended that view to transgender people via what Flores describes as a “mechanism of attitude generalization.”

In polling, Americans typically say they favor smaller government in general while supporting many specific government programs. When Bill Clinton took office in 1993, Americans said they favored “a smaller government providing fewer services” over “a bigger government providing more services” by 37 percentage points. When Obama took power in 2009, the margin was a mere eight points. And despite the president’s many economic interventions, the most recent time Pew asked that question, in September 2014, the margin was exactly the same.

This intervention has sparked an angry response on the Republican right, but not among Americans as a whole.

On health care, the story is similar: no public backlash. When Obama signed the Affordable Care Act in March 2010, most polls showed Americans opposing it by about eight to 10 points. Today, the margin is almost identical

Little has changed on taxes, either, even though Obama allowed some of the tax cuts passed under George W. Bush to expire. The percentage of Americans who say they pay more than their fair share in taxes is about the same as it was in the spring of 2010 (

in an era when government has grown more intrusive, African American activists have grown more confrontational, and long-standing assumptions about sexual orientation and gender identity have been toppled, most Americans are not yelling “stop,” as they began doing in the mid-1960s. The biggest reason: We’re not dealing with the same group of Americans.

On issue after issue, it is the young who are most pleased with the liberal policy shifts of the Obama era, and most eager for more

It is largely because of them that the percentage of Americans who want government to “promote traditional values” is now lower than at any other time since Gallup began asking the question in 1993, and that the percentage calling themselves “socially liberal” now equals the percentage calling themselves “socially conservative” for the first time since Gallup began asking that question in 1999.

Millennials are also sustaining support for bigger government. The young may not have a high opinion of the institutions that represent them, but they nonetheless want those institutions to do more

They were also 25 points more likely than those 65 and older to approve of Occupy Wall Street and 36 points more favorable toward socialism, which they actually preferred to capitalism, 49 percent to 46 percent. As the Pew report put it, “Millennials, at least so far, hold ‘baked in’ support for a more activist government.

The press often depicts American politics as a battle pitting ever more liberal Democrats against ever more conservative Republicans. Among the young, however, that’s inaccurate. Young Democrats may be more liberal than their elders, but so are young Republicans. According to Pew, a clear majority of young Republicans say immigrants strengthen America, half say corporate profits are too high, and almost half say stricter environmental laws are worth the cost—answers that sharply distinguish them from older members of the GOP.

Asked how they categorize themselves ideologically, more than two-thirds of Republican Millennials call themselves either “liberal” or “mixed,” while fewer than one-third call themselves “conservative.” Among the oldest Republicans, that breakdown is almost exactly reversed.

Millennials are not liberal primarily because they are young. They are liberal because their formative political experiences were the Iraq War and the Great Recession, and because they make up the most secular, most racially diverse, least nationalistic generation in American history. And none of that is likely to change.

America is not governed by public-opinion polls, after all. Congressional redistricting, felon disenfranchisement, and the obliteration of campaign-finance laws all help insulate politicians from the views of ordinary people, and generally empower the right. But despite these structural disadvantages, Obama has enacted a more consequential progressive agenda than either of his two Democratic predecessors did

If Clinton does win, it’s likely that on domestic policy, she will govern to Obama’s left. (On foreign policy, where there is no powerful left-wing activist movement like Occupy or Black Lives Matter, the political dynamics are very different.) Clinton’s campaign proposals already signal a leftward shift. And people close to her campaign suggest that among her top agenda items would be paid family leave, debt-free college tuition, and universal preschool

Clinton will face this reality from her first day in office. And she will face it knowing that because she cannot inspire liberals rhetorically as Obama can, they will be less likely to forgive her heresies on policy. Like Lyndon B. Johnson after John F. Kennedy, she will have to deliver in substance what she cannot deliver in style.

it’s likely that any Republican capable of winning the presidency in 2016 would govern to the left of George W. Bush. In the first place, winning at all would require a different coalition. When Bush won the presidency in 2000, very few Millennials could vote. In 2016, by contrast, they will constitute roughly one-third of those who turn out

In 2000, African Americans, Hispanics, and Asians constituted 20 percent of voters. In 2016, they will constitute more than 30 percent.

even if the 2016 Republican nominee wins 60 percent of the white vote (more than any GOP nominee in the past four decades except Reagan, in 1984, has won), he or she will still need almost 30 percent of the minority vote. Mitt Romney got 17 percent.

This need to win the votes of Millennials and minorities, who lean left not just on cultural issues but on economic ones, will shape how any conceivable Republican president campaigns in the general election, and governs once in office.

If America’s demographics have changed since the Bush presidency, so has the climate among conservative intellectuals. There is now an influential community of “reformocons”—in some ways comparable to the New Democratic thinkers of the 1980s—who believe Republicans have focused too much on cutting taxes for the wealthy and not enough on addressing the economic anxieties of the middle and working classes.

The candidate closest to the reformocons is Rubio, who cites several of them by name in his recent book. He says that partially privatizing Social Security, which Bush ran on in 2000 and 2004, is an idea whose “time has passed.” And unlike Bush, and both subsequent Republican presidential nominees, Rubio is not proposing a major cut in the top income-tax rate. Instead, the centerpiece of his economic plan is an expanded child tax credit, which would be available even to Americans who are so poor that they don’t pay income taxes

it’s likely that were he elected, Rubio wouldn’t push through as large, or as regressive, a tax cut as Bush did in 2001 and 2003. Partly, that’s because a younger and more ethnically diverse electorate is less tolerant of such policies. Partly, it’s because Rubio’s administration would likely contain a reformocon faction more interested in cutting taxes for the middle class than for the rich. And partly, it’s because the legacy of the Bush tax cuts themselves would make them harder to replicate

A key figure in passing the Bush tax cuts was Federal Reserve Chairman Alan Greenspan, who in 2001 warned that unless Washington lowered tax rates, surpluses might grow too large, thus producing a dangerous “accumulation of private assets by the federal government.” Greenspan’s argument gave the Bush administration crucial intellectual cover. But the idea now looks laughable. And it’s hard to imagine the current Federal Reserve chair, Janet Yellen, endorsing large upper-income tax cuts in 2017.

the kind of centrist, Chamber of Commerce–friendly Democrats who helped Bush pass his tax plan in 2001—including Max Baucus, John Breaux, Mary Landrieu, Zell Miller, Max Cleland, Tim Johnson, Blanche Lambert Lincoln—barely exist anymore. The Democrats’ shift left over the past decade and a half means that a President Rubio would encounter more militant opposition than Bush did in 2001

the next Republican president won’t be able to return the nation to the pre-Obama era.

That’s what happened when Dwight Eisenhower followed Franklin D. Roosevelt and Harry Truman. Ike moderated the growth in government expansion that had begun in the 1930s, but he didn’t return American politics to the 1920s, when the GOP opposed any federal welfare state at all. He in essence ratified the New Deal

It’s also what happened when Bill Clinton followed Ronald Reagan and George H. W. Bush. By passing punitive anticrime laws, repealing restrictions on banks, signing NAFTA, cutting government spending to balance the budget, reforming welfare, and declaring that the “era of big government is over,” Clinton acknowledged that even a Democratic president could not revive the full-throated liberalism of the 1960s and ’70s. He ratified Reaganism.

Barack Obama sought the presidency hoping to be the Democrats’ Reagan: a president who changed America’s ideological trajectory. And he has changed it. He has pushed the political agenda as dramatically to the left as Reagan pushed it to the right, and, as under Reagan, the public has acquiesced more than it has rebelled.

“It took something high profile to get people to understand, and it needed something in the media to make people aware,” Dr. Stewart said, referring to Benjamin’s death. “Even if it just means we’re preventing another Ben Robinson and not addressing dementia, that’s still very important. We’ve got to get things to change.”

Much of what Mr. Robinson and Dr. Stewart have accomplished is second nature in the United States, where concussions have been a growing part of the public dialogue for several years. Coaches and players in many sports are now taught that concussions, brain injuries resulting from a blow to the head or whiplash, can lead to headaches, memory loss, dizziness, sensitivity to light and other problems.

After an outcry from scientists, retired players and family members of injured and deceased athletes, the N.F.L. and other leagues have adopted protocols during games to detect concussions, pull players from the field, administer on-the-spot tests and detail when they can return to play.

“Scotland is a great example of a team of passionate advocates creating change in their community,” he said. “It’s a template that I hope others follow.”

Concussions were far from Mr. Robinson’s mind when his son joined his teammates from Carrickfergus Grammar School to play their rivals from Dalriada that day.

Soccer was Benjamin’s first love, but when he was 11, he took up rugby, which was mandatory at his new school. Initially, he did not enjoy the sport. But he warmed to it after winning the award for most improved player. He did strength and conditioning drills to add muscle, and arm wrestled with his father.

The night before the game, his son watched “Invictus,” the film about South Africa’s victory in the 1995 Rugby World Cup. He slept that night in his uniform. When his mother dropped him off at the field the next day, Benjamin flashed a thumbs-up sign.

But just minutes into the second half, Benjamin collided with another player, whose shoulder hit him in the chest, according to Mr. Robinson, who obtained a DVD of the match from the police. His son’s head whipped back, and he fell. The coach came to look at Benjamin, who was on the ground for about 90 seconds, and helped him to his feet. A doctor who was watching his son play for Dalriada briefly walked onto the field but then turned back.

As time ran down, Benjamin made a tackle and then collapsed. The game was stopped. Ms. Walton ran onto the field, where Benjamin’s teammate told her that he was out cold. He was rushed to Royal Victoria Hospital in Belfast.

When Mr. Robinson and his wife, Carol, arrived at the hospital, he knew the situation was dire from the faces of the staff. His son was on life support. The doctors said that his brain injury looked like it was sustained in a car accident and that he had a slim chance of surviving.

Initially, though, a police investigator deferred to the schools when it came to gathering comments from Benjamin’s teammates and opponents. Officials at Carrickfergus declined to discuss the case.

Ms. Walton and Mr. Robinson, though, had to piece together much of what happened on their own. One break came while Ms. Walton was visiting her son’s grave — which she said she did every day — and met one of his teammates, who was out jogging. He told her that Benjamin had been knocked out during the match, not just hit at the end, as had been contended.

The big break came when a police officer gave Mr. Robinson a copy of a video taken of the match by a student. Mr. Robinson watched the shaky footage repeatedly and confirmed that his son suffered not one big blow, but at least three, and that the coach attended to him several times.

Yet she effectively absolved the coach and referee, who were not “made aware of Benjamin’s neurological complaints,” even though the coach can be seen on the video checking on him after a hit during the match. She implied that Benjamin could have let them know about his condition, even though experts say concussion victims often cannot adequately communicate what they are experiencing.

Soon after, Mr. and Ms. Robinson, Dr. Stewart and James Robson, the chief medical officer of Scottish Rugby, met with Scotland’s sport and education officials to lobby for change. A concussion-awareness leaflet was produced at the beginning of 2014.

It has been an unlikely road for Mr. Robinson and Dr. Stewart, an avid bike rider with no experience as a sideline doctor. But about five years ago, even before Benjamin’s death, Dr. Stewart began to get calls from former professional players and had conversations with Scottish Rugby as it tried to address brain trauma and degenerative brain disease.

Still, some sports executives have anonymously challenged Dr. Stewart. In one match in April in London, Oscar, the Brazilian star player on Chelsea who is known by one name, collided violently with the goalkeeper yet was not immediately taken out of the game. There are no concussion spotters at Premier League matches, but team and league officials could watch a replay of the game later. That is why Dr. Stewart — an adviser to the Football Association — was dismayed that Oscar was in uniform three days later, violating the league’s return-to-play guidelines that require at least six days of rest.

“I don’t need to stand up in front of a conference of sports medicine and be personally criticized,” he said. “But then I’ll get a call from Peter, who is enthused about something we’ve done with the leaflets, or some research collaborators who are keen to move forward, and I say, ‘Ah, for all the small minds that are critical and obviously trying to deny the inevitable signs, there are a whole bunch of people who are having a positive effect on it.’

On a chilly evening in late October, with teenagers practicing on a nearby field, Lianne Brunton, the club’s physical therapist, showed off the test on a tablet computer. At the start of the season, hundreds of youth and adult players are timed as they read aloud a series of numbers on several screens. If a player is suspected of having a concussion during a match, he or she is taken off and asked to read the numbers again. Players who take longer are evaluated further.

The test, which is widely used in the United States, is another example of how the grass-roots campaign to improve safety standards after Benjamin’s death has changed attitudes.

The Green New Deal, first and foremost, can be understood as trying to fix the BAD problem. In the long term, it’s an ambitious package of laws that will touch every sector of the economy. The Sunrise Movement, a youth-led activism group that has pushed for the policy, has listed seven demands that any Green New Deal must satisfy. They range from requiring the U.S. to get 100 percent of its electricity from renewable sources to “decarbonizing, repairing and improving transportation and other infrastructure.” They also call for a massive investment in technology that could directly remove carbon dioxide from the atmosphere.

The single most crucial aspect of the Green New Deal is its proposed job guarantee, a controversial policy that says that every American can have a job with the government if they want one. Data for Progress, a leftist advocacy group, claims that the Green New Deal could generate 10 million new jobs across the country over 10 years.

This policy—a job for every American who wants one—reflects what the party learned from fighting Obamacare’s repeal. Obamacare provides a revealing view into how economists think about policy versus how people experience it

Franklin D. Roosevelt’s New Deal was not a tax, even if it included taxes; it’s remembered instead as the greatest of all stimulus and jobs bills. If Democrats take the White House during a recession, they will have a far easier time passing a Green New Deal than a carbon tax.

Obamacare survived because it gave two new superpowers to voters. The first was the power never to be denied health insurance for preexisting conditions, and the second was free or cheap health insurance through Medicaid. The reason Americans jammed the Capitol Hill switchboards last year to protest the repeal—and pulled the lever for Democrats in November—wasn’t that they valued Obamacare’s elegant cost-control mechanism. They wanted to keep their superpowers.

Fixing climate change will include lots of technocratic tweaks, lots of bills about dirt. They will be hard to defend against later repeal. So it would be nice if lawmakers could wed them to a new benefit, a superpower that people will fight for years after passage. Hence the job guarantee—a universal promise of employment meant to win over Americans in general and create more union jobs in particular.

The policy aligns with emerging Democratic strategy, too. The Green New Deal is policy-by-slogan, like “Medicare for All” or “Free Community College” or “Abolish ICE.” Those phrases capture a worldview, a promise, and a vision of how life would be different after their passage. They mirror the pungency, if not the politics, of Trump’s promise to “Build the wall.”

as far as policy makers are concerned, Obamacare comprises a set of clever tweaks and rules meant to change how insurance markets work and lower the cost of health care. Before the law passed, Democratic lawmakers cared deeply about getting those tweaks right.

For her first day on Capitol Hill, and her first public act as a representative-elect, Ocasio-Cortez chose to focus on climate change

Many Americans first heard of the Green New Deal early last month, after Ocasio-Cortez made a surprise appearance at a demonstration in Nancy Pelosi’s office

“People are beginning to understand that climate change is here in the United States, here in my state, in my community, affecting the people and places I care about, and now,”

Asked whether people in the United States were being harmed by global warming “right now,” 48 percent of the respondents agreed, an increase of nine percentage points since March. And 49 percent said they believed they would be personally harmed by global warming, a seven-point jump over the same period.

he attributed the recent increases to a number of extreme weather events with plausible connections to a warming planet, and to the publicity that surrounded two major scientific reports on climate change last year.

The changes in public opinion over the last year were also tied to politics, Dr. Leiserowitz said, and to the efforts of President Trump to deny the scientific evidence of climate change.

“Every time he talks about climate change he drives more media attention to the exact issue,” Dr. Leiserowitz said

Mr. Trump’s approach to politics is so divisive, Dr. Leiserowitz said, that when he takes a strong stand on climate change and other issues, “he tends to drive a majority of the country in the opposite direction.”

In the poll, a record 62 percent of respondents understood that humans are the main cause of climate change, a four-point rise since March; those attributing it mostly to natural causes were at a record-low 23 percent, a drop of five points over the same period.

She noted that 41 percent of respondents in the poll said they talked about global warming with family and friends “often” or “occasionally,” and 56 percent said they heard about the topic in the news media at least once a month, a 13 percent increase since 2015. “It’s becoming harder and harder to avoid conversations about climate change,” she said.

The result is another lesson that the politics of climate change isn’t as simple as Western cultural elites claim. Labor thought that droughts, heat waves and brush fires would cause voters to embrace its climate solutions. Young people say they care about the issue, often as virtue-signaling

Faced with lost jobs, higher taxes and a higher cost of living, voters in democracies time and again have rejected climate-change policies that wouldn’t in the end matter all that much to the climate.
