The data implies that demographic shifts played a somewhat smaller role in Mr. Obama’s re-election than the postelection narrative suggested. Even if the electorate were as old and as white as it was in 2004, Mr. Obama would have won, because of the gains he made among white voters in states like New Mexico, Colorado and Iowa.

All of this is good news for a Republican who intends to win with greater strength among white working-class voters, like Mr. Trump.

the Upshot analysis shows that all of Mr. Obama’s weaknesses were in the South — defined as the former Confederacy plus Oklahoma, Missouri, Kentucky and West Virginia — where he won just 26 percent.

Yet it’s hard to argue that the attacks on Bain Capital were responsible for Mr. Obama’s gains among young and college-educated white voters. These voters moved decisively in Mr. Obama’s direction, perhaps in part because of cultural issues. If that’s right, Mr. Trump will be hard pressed to reverse Mr. Obama’s gains — and there’s plenty of evidence he could slip further.

According to data from L2, a nonpartisan voter file vendor, the missing white voters were far more likely to be registered Democrats, or to have participated in Democratic primaries, than the white voters who actually did turn out.

Even if the missing white voters were disproportionately Republican, a return to previous turnout levels wouldn’t have been anywhere near enough to get Mr. Romney over the top. There were far fewer missing white voters in the battleground states than there were nationally. There weren’t close to enough of them to flip the outcome in key states.

The real pool of missing white voters are those who haven’t participated in any recent election, or aren’t even registered to vote. There are millions of these missing white voters — but they will be much harder to mobilize. Many are young, and might not be especially favorable to Mr. Trump. The older ones are true bystanders in American politics.

If Mr. Trump lost five points among well-educated white voters and Hispanics, which is how he’s doing in current polls, his target for white working-class voters would quickly skyrocket. In a battleground state like Colorado, for example, he would need to gain 15 percentage points more of the white working class

What’s happening in Ferguson is the result of several recent historical factors and deeply entrenched racial attitudes, as well as a breakdown in participatory democracy.

In Ferguson, the American public has awakened to images of local police, fully decked out in surplus military gear from our recent wars in Iraq and Afghanistan, who are deploying all that in accordance with a now widespread “broken windows” policy, which was established on the hypothesis that if small crimes and misdemeanors are checked in certain neighborhoods, more serious crimes will be deterred. But this policy quickly intersected with police racial profiling already in existence to result in what has recently become evident as a propensity to shoot first.

How does this “broken windows” policy relate to the tragic deaths of young black men/boys? N.Z.:People are now stopped by the police for suspicion of misdemeanor offenses and those encounters quickly escalate.

Young black men are the convenient target of choice in the tragic intersection of the broken windows policy, the domestic effects of the war on terror and police racial profiling.

Why do you think that young black men are disproportionately targeted? N.Z.: Exactly why unarmed young black men are the target of choice, as opposed to unarmed young white women, or unarmed old black women, or even unarmed middle-aged college professors, is an expression of a long American tradition of suspicion and terrorization of members of those groups who have the lowest status in our society and have suffered the most extreme forms of oppression, for centuries.

Police in the United States are mostly white and mostly male. Some confuse their work roles with their own characters. As young males, they naturally pick out other young male opponents. They have to win, because they are the law, and they have the moral charge of protecting.

So young black males, who have less status than they do, and are already more likely to be imprisoned than young white males, are natural suspects.

Besides the police, a large segment of the white American public believes they are in danger from blacks, especially young black men, who they think want to rape young white women. This is an old piece of American mythology that has been invoked to justify crimes against black men, going back to lynching. The perceived danger of blacks becomes very intense when blacks are harmed.

The term “white privilege” is misleading. A privilege is special treatment that goes beyond a right. It’s not so much that being white confers privilege but that not being white means being without rights in many cases. Not fearing that the police will kill your child for no reason isn’t a privilege. It’s a right. 

that is what “white privilege” is meant to convey, that whites don’t have many of the worries nonwhites, especially blacks, do.

Other examples of white privilege include all of the ways that whites are unlikely to end up in prison for some of the same things blacks do, not having to worry about skin-color bias, not having to worry about being pulled over by the police while driving or stopped and frisked while walking in predominantly white neighborhoods, having more family wealth because your parents and other forebears were not subject to Jim Crow and slavery.

Probably all of the ways in which whites are better off than blacks in our society are forms of white privilege.

Over half a century later, it hasn’t changed much in the United States. Black people are still imagined to have a hyper-physicality in sports, entertainment, crime, sex, politics, and on the street. Black people are not seen as people with hearts and minds and hopes and skills but as cyphers that can stand in for anything whites themselves don’t want to be or think they can’t be.

race is through and through a social construct, previously constructed by science, now by society, including its most extreme victims. But, we cannot abandon race, because people would still discriminate and there would be no nonwhite identities from which to resist. Also, many people just don’t want to abandon race and they have a fundamental right to their beliefs. So race remains with us as something that needs to be put right.

But by the end of the early 1980s recession, the sector had lost almost 3 million jobs. Today, there are about 12 million people working in manufacturing, altogether. In the cities where these jobs were concentrated, the fallout was particularly brutal.

The high tariff wall allowed American manufacturing to introduce all available innovations into U.S.-based factories without the outsourcing that has become common in the last several decades. The lack of competition from immigrants and imports boosted the wages of workers at the bottom and contributed to the remarkable “great compression” of the income distribution during the 1940s, 1950s, and 1960s. Thus the closing of the American economy through restrictive immigration legislation and high tariffs may indirectly have contributed to the rise of real wages … and the general reduction of inequality from the 1920s to the 1950s.

What happened? The road from there to Trump is long and punctuated with many markers. But here are three significant turns: the 1968 election; the 1979 peak in manufacturing employment, and the 2008 election of Barack Obama.

In a shockingly frank 1981 interview looking back at the 1968 election, the Republican strategist Lee Atwater explained how Nixon disguised his appeal to anti-black voters in the language of economic angst. “By 1968 you can’t say ‘nigger’—that hurts you, backfires. So you say stuff like, uh, forced busing, states’ rights, and all that stuff, and you’re getting so abstract. Now, you’re talking about cutting taxes, and all these things you’re talking about are totally economic things and a byproduct of them is, blacks get hurt worse than whites.”

Was the white south’s shift to the Republican column really all about civil rights? In a 2015 study, Yale University researchers drawing from Gallup surveys dating back to 1958 concluded that although southern white Democrats held racist views before the 1960s, the correlation between “conservative racial views” and “Democratic identification” disappeared after Kennedy proposed the Civil Rights Act in 1963.

Essentially, almost all of those voters became Republicans. “Defection among racially conservative whites explains all of the decline in relative white Southern Democratic identification between 1958 and 1980” and three-quarters of the decline until 2000, they concluded.

The most important American industry for most of the 20th century had been manufacturing. Once employing more than a third of the private workforce, and mostly men without a college education, manufacturing employment peaked in the summer of 1979 at almost 20 million workers.

The 1950s was a remarkable decade for blue-collar male workers. Union membership in the private sector peaked at 35 percent. The male labor-participation rate peaked in 1951. The next year, unemployment fell under 3 percent for the only period on record. Factories that once made shrapnel turned out lawn mowers and washing machines that supplied a happy migration to the suburbs. All this occurred within an economy that was uniquely closed, as the economist Robert Gordon wrote in his book The Rise and Fall of American Growth:

Since 1980, the share of men between 25 and 54 who are neither working nor looking for work has increased with each passing decade. Since 1980, this figure, called the "inactivity rate," has more than doubled

Meanwhile, work has shifted toward service-sector jobs where less-educated women have fared better than men. Women without a college degree are earning more than they were 20 years ago, but since 1990, median real earnings for men without a college degree have fallen 13 percent.

nly one age-and-ethnic group is dying at higher rates than they were 15 years ago: middle-aged American whites without a college education.

. In 2004, white Republicans and white Democrats were similarly likely to say that "too much" money was spent to improve conditions for black people. Eight years later, Republicans were three times more likely to agree.

although the expression of racism by all whites toward blacks has decreased over time, "they’ve failed to decrease under Obama” among Republicans.

The reemergence of racial antagonism is concentrated among Trump supporters. Six out of ten of them think Obama is a Muslim, and only 21 percent acknowledge that the president was born in the United States.

economic anxiety can amplify racial threat effects by leading the majority to fear losing scarce resources to the rising minority. According to "group position theory,” or “group threat,” people in an ethnic majority identify with each other and feel threatened when their position in the cultural hierarchy is tenuous

Berkeley, applied group position theory to the rise of the Tea Party, arguing that racial resentment was the motor of the movement. They concluded that “the election of the first nonwhite president [and] the rising minority population have been perceived as threatening the relative standing of whites in the U.S.”

In short, scarcity triggers tribalism. Despite the long decline in racism among most American voters, prejudice is blooming where voters are most pessimistic and afraid.

in 1972, activist Phyllis Schlafly launched an anti-feminist crusade, STOP ERA, which reframed this notion of choice. The ERA, Schlafly insisted, would actually require women to put their children in government day care and put themselves on the front lines in warfare. Schlafly depicted feminism as a mandate and presented anti-feminism as a morally superior alternative.

Schlafly had successfully organized Southern white, mostly religious women — the very people the GOP needed to recapture the South after Jimmy Carter’s victories there in 1976. Reagan appealed to these same Southern white women not by overtly opposing women’s equality, but by expressing his concern that the ERA would weaken the American family and diminish special protections for women.

Southern white culture had long been a stronghold of traditional gender norms. In theory, the ideal Southern white woman was placed on a pedestal: financially supported, removed from the hardships of public life and protected from dangerous black men she was taught to fear. For poor and working-class white women, the pedestal and its protections were more aspirational than real, but the ideal was nonetheless powerful and pervasive in the South.

This advantage helped propel Reagan to the White House and reignited the partisan transformation of the South that had stalled after Richard Nixon’s resignation.

more distorting, coverage of this new gender gap often ignored significant racial and regional distinctions. Reagan actually won white women by a 52-39 margin, which jumped to 59-34 percent among Southern white women. Women’s perceived preference for Carter really only reflected the way that the president had trounced Reagan among African American women.

This post-election narrative took root in part because the idea that white women, particularly in the South, would not only hand the presidency to the party that opposed the ERA, but that they would do so because it opposed the ERA, was just too hard to accept

The next time a woman appeared on the Democratic ticket — this time at the top — the problem of the oversimplified notion of a gender gap was even clearer. Hillary Clinton crushed Donald Trump among nonwhite women and even won white women living outside the South. However, among white women in the states of the former Confederacy, Trump, who was endorsed early on by Phyllis Schlafly, bested Clinton by 25 points, 58 percent to 33 percent.

Courting anti-feminist white women was a critical part of the GOP’s Southern strategy, one often forgotten today, and it has solidified them into an integral component of the Republican base. Their preferences help explain why feminist candidates struggle in the South, why the gender gap has been misunderstood, why the ERA failed and why the 2016 election turned out the way it did

If Democrats hope to build a winning coalition in 2020, anti-feminist white women must be considered distinct not only from women of color, but also from feminist white women both inside the South and beyond its borders

since the civil-rights movement, Republicans (and many non-Republicans) have expressed two conflicting racial mantras: (1) racism no longer exists, and (2) racism is spreading against white people. Since Joe Biden’s election, this second mantra has overtaken the first.

White-supremacist ideology lives on what Heather McGhee calls the “zero-sum myth,” the idea that progress for people of color necessarily comes at white folks’ expense.

It fearmongers about the future: If white people are not worshipped in schools, then they will be demonized; if white people don’t reign supreme, then they will be subjugated; if white people don’t hoard resources and opportunities, then they will be starved; if white people cannot kill at will, then they will be killed at will

White violence is presumed to be self-defense. Defending yourself against a white supremacist is presumed to be a criminal act.

Extreme fear perhaps breeds this extreme fear. White supremacists probably fear revenge, retaliation, the tables turning—as they wipe the blood of democracy, of equality, of the dying and dead off their hands

they know the level of brutality they have leveled against people of color and their white allies.

They probably can’t imagine that Indigenous anti-racists just want their land back and aren’t genocidal; that Black anti-racists just want reparations and don’t want to enslave; that Asian anti-racists just want to be visible and don’t want to render white people invisible; that Latino and Middle Eastern anti-racists just want to flee violence and don’t want to invade predominantly white nations.

History reproduces itself. But when people don’t know history—or are barred from learning it—how can they ever recognize its reproduction?

That’s still well below the national median, but the conditions of the White population are dismal: a median household income of $24,800, only 41% with any post-high school education, and 30% living in poverty.

In a growing nationwide trend, the median household incomes of people of color, according to the U.S. Census Bureau, now exceed those of White people in nearly 200 of the 1,500 Republican-trifecta counties—those in which the party controls the governor’s office and both legislative chambers of state government (see Figure 1)

In the most telling statistics, White people in Antlers are nearly twice as likely to die by guns as Native Americans (see Figure 2). Compared with Whites nationally, Antlers Whites suffer excessive death rates from drugs and alcohol (1.3 times the national average), suicide (1.5 times), all violent deaths (1.8 times), homicide (2.5 times), and gunfire (2.6 times).

When I was growing up in Antlers 60 years ago and visited it 20 years ago, my family’s old block consisted of well-kept middle-class homes fronting yards for chickens and horses. On my latest visit in January 2022, I found the houses all boarded up or blowing open in the wind (see photo at top). There are hundreds of abandoned dwellings with collapsing roofs and walls and junk-filled empty lots alongside barely intact, yet still occupied, houses.

Antlers is not all devastation, however. It sports a gleaming Choctaw-built travel center financed by casino revenues, which are also invested in local Native Americans’ well-being.

Across America, the partisan gap in gross domestic product per capita is also huge and growing: $77,900 in Democratic-voting areas, compared with $46,600 in Republican-voting areas

444 Republican counties have a GDP per capita of under $30,000, and 10 times as many people live in those counties than in the seven similarly low-GDP Democratic counties.

Whites in about 40% of all Republican counties lost income over the past two decades. And Trump’s administration was no help to his base. During his presidency, the overall Democrat–Republican GDP per capita gap widened by another $1,800.

For the largest urbanized states, the three with Democratic control of all branches of government (California, New York, and Illinois) had GDPs per capita vastly higher than the three biggest Republican-controlled states (Texas, Florida, and Ohio).

The right-wing canard that hardworking White people subsidize welfare-grubbing cities is backward. Democrat-voting counties, with 60% of America’s population, generate 67% of the nation’s personal income, 70% of the nation’s GDP, 71% of federal taxes, 73% of charitable contributions, and 75% of state and local taxes.

Mirroring Antlers, White Republican America also suffers violent death rates, including from suicide, homicide, firearms, and drunken driving crashes, far higher than Whites in Democratic America and higher than non-White people everywhere.

To top it off, Republican-governed Americans are substantially more likely to die from COVID-19.

As the death gap between Republican and Democratic areas widens over time, the life expectancy for Whites in Republican-voting areas (77.6 years) is now three years shorter than that of Whites in Democratic areas (80.6 years), shorter than those of Asians and Latino people everywhere, and only a few months longer than Black and Native Americans in Democratic areas.

That White people are falling behind across key economic, health, and safety indexes is not due to victimization by immigrants and liberal conspiracies, however, but to victimization by other Whites and self-inflicted alcoholism, drug overdose, and suicide.

Aside from the problem that Republican members of congress (and two recalcitrant Democrats) have sabotaged beneficial initiatives, former President Barack Obama already tried that. From 2010 to 2016, the Obama administration’s economic recovery measures fostered millions of new jobs and thousands of dollars in real median income growth for Whites in urban and most rural areas alike, reversing the recession under Republican George W. Bush’s presidency.

Is the solution to undividing America massive federal programs to improve Republican America’s struggling economies and troubled social conditions, then?

To be black in the Baltimore of my youth was to be naked before the elements of the world, before all the guns, fists, knives, crack, rape, and disease. The law did not protect us. And now, in your time, the law has become an excuse for stopping and frisking you, which is to say, for furthering the assault on your body

There is nothing uniquely evil in these destroyers or even in this moment. The destroyers are merely men enforcing the whims of our country, correctly interpreting its heritage and legacy. This legacy aspires to the shackling of black bodies

It is hard to face this. But all our phrasing—race relations, racial chasm, racial justice, racial profiling, white privilege, even white supremacy—serves to obscure that racism is a visceral experience, that it dislodges brains, blocks airways, rips muscle, extracts organs, cracks bones, breaks teeth

ou must never look away from this. You must always remember that the sociology, the history, the economics, the graphs, the charts, the regressions all land, with great violence, upon the body.

And should one live in such a body? What should be our aim beyond meager survival of constant, generational, ongoing battery and assault? I have asked this question all my life.

The question is unanswerable, which is not to say futile. The greatest reward of this constant interrogation, of confrontation with the brutality of my country, is that it has freed me from ghosts and myths.

I was afraid long before you, and in this I was unoriginal. When I was your age the only people I knew were black, and all of them were powerfully, adamantly, dangerously afraid. It was always right in front of me. The fear was there in the extravagant boys of my West Baltimore neighborhood

The fear lived on in their practiced bop, their slouching denim, their big T- shirts, the calculated angle of their baseball caps, a catalog of behaviors and garments enlisted to inspire the belief that these boys were in firm possession of everything they desired.

But a society that protects some people through a safety net of schools, government-backed home loans, and ancestral wealth but can only protect you with the club of criminal justice has either failed at enforcing its good intentions or has succeeded at something much darker.

still and all I knew that we were something, that we were a tribe—on one hand, invented, and on the other, no less real. The reality was out there on the Yard, on the first warm day of spring when it seemed that every sector, borough, affiliation, county, and corner of the broad diaspora had sent a delegate to the great world party

I remember being amazed that death could so easily rise up from the nothing of a boyish afternoon, billow up like fog. I knew that West Baltimore, where I lived; that the north side of Philadelphia, where my cousins lived; that the South Side of Chicago, where friends of my father lived, comprised a world apart. Somewhere out there beyond the firmament, past the asteroid belt, there were other worlds where children did not regularly fear for their bodies

I came to understand that my country was a galaxy, and this galaxy stretched from the pandemonium of West Baltimore to the happy hunting grounds of Mr. Belvedere. I obsessed over the distance between that other sector of space and my own. I knew that my portion of the American galaxy, where bodies were enslaved by a tenacious gravity, was black and that the other, liberated portion was not. I knew that some inscrutable energy preserved the breach. I felt, but did not yet understand, the relation between that other world and me. And I felt in this a cosmic injustice, a profound cruelty, which infused an abiding, irrepressible desire to unshackle my body and achieve the velocity of escape.

Before I could escape, I had to survive, and this could only mean a clash with the streets, by which I mean not just physical blocks, nor simply the people packed into them, but the array of lethal puzzles and strange perils which seem to rise up from the asphalt itself. The streets transform every ordinary day into a series of trick questions, and every incorrect answer risks a beat-down, a shooting, or a pregnancy. No one survives unscathed

When I was your age, fully one-third of my brain was concerned with who I was walking to school with, our precise number, the manner of our walk, the number of times I smiled, who or what I smiled at, who offered a pound and who did not—all of which is to say that I practiced the culture of the streets, a culture concerned chiefly with securing the body.

Why were only our heroes nonviolent? Back then all I could do was measure these freedom-lovers by what I knew. Which is to say, I measured them against children pulling out in the 7-Eleven parking lot, against parents wielding extension cords, and the threatening intonations of armed black gangs saying, “Yeah, nigger, what’s up now?” I judged them against the country I knew, which had acquired the land through murder and tamed it under slavery, against the country whose armies fanned out across the world to extend their dominion. The world, the real one, was civilization secured and ruled by savage means. How could the schools valorize men and women whose values society actively scorned? How could they send us out into the streets of Baltimore, knowing all that they were, and then speak of nonviolence?

the beauty of the black body was never celebrated in movies, in television, or in the textbooks I’d seen as a child. Everyone of any import, from Jesus to George Washington, was white. This was why your grandparents banned Tarzan and the Lone Ranger and toys with white faces from the house. They were rebelling against the history books that spoke of black people only as sentimental “firsts”—first black four-star general, first black congressman, first black mayor—always presented in the bemused manner of a category of Trivial Pursuit.

erious history was the West, and the West was white. This was all distilled for me in a quote I once read, from the novelist Saul Bellow. I can’t remember where I read it, or when—only that I was already at Howard. “Who is the Tolstoy of the Zulus?,” Bellow quipped

this view of things was connected to the fear that passed through the generations, to the sense of dispossession. We were black, beyond the visible spectrum, beyond civilization. Our history was inferior because we were inferior, which is to say our bodies were inferior. And our inferior bodies could not possibly be accorded the same respect as those that built the West. Would it not be better, then, if our bodies were civilized, improved, and put to some legitimate Christian use?

now I looked back on my need for a trophy case, on the desire to live by the standards of Saul Bellow, and I felt that this need was not an escape but fear again—fear that “they,” the alleged authors and heirs of the universe, were right. And this fear ran so deep that we accepted their standards of civilization and humanity.

“Tolstoy is the Tolstoy of the Zulus,” wrote Wiley. “Unless you find a profit in fencing off universal properties of mankind into exclusive tribal ownership.” And there it was. I had accepted Bellow’s premise. In fact, Bellow was no closer to Tolstoy than I was to Nzinga. And if I were closer it would be because I chose to be, not because of destiny written in DNA. My great error was not that I had accepted someone else’s dream but that I had accepted the fact of dreams, the need for escape, and the invention of racecraft.

The destroyers will rarely be held accountable. Mostly they will receive pensions.

I could see now that that world was more than a photonegative of that of the people who believe they are white. “White America” is a syndicate arrayed to protect its exclusive power to dominate and control our bodies. Sometimes this power is direct (lynching), and sometimes it is insidious (redlining). But however it appears, the power of domination and exclusion is central to the belief in being white, and without it, “white people” would cease to exist for want of reasons

here will surely always be people with straight hair and blue eyes, as there have been for all history. But some of these straight-haired people with blue eyes have been “black,” and this points to the great difference between their world and ours. We did not choose our fences. They were imposed on us by Virginia planters obsessed with enslaving as many Americans as possible. Now I saw that we had made something down here, in slavery, in Jim Crow, in ghettoes. At The Mecca I saw how we had taken their one-drop rule and flipped it. They made us into a race. We made ourselves into a people.

Think of all the embraces, all the private jokes, customs, greetings, names, dreams, all the shared knowledge and capacity of a black family injected into that vessel of flesh and bone. And think of how that vessel was taken, shattered on the concrete, and all its holy contents, all that had gone into each of them, was sent flowing back to the earth. It is terrible to truly see our particular beauty, Samori, because then you see the scope of the loss. But you must push even further. You must see that this loss is mandated by the history of your country, by the Dream of living white.

I don’t know if you remember how the film we saw at the Petersburg Battlefield ended as though the fall of the Confederacy were the onset of a tragedy, not jubilee. I doubt you remember the man on our tour dressed in the gray wool of the Confederacy, or how every visitor seemed most interested in flanking maneuvers, hardtack, smoothbore rifles, grapeshot, and ironclads, but virtually no one was interested in what all of this engineering, invention, and design had been marshaled to achieve. You were only 10 years old. But even then I knew that I must trouble you, and this meant taking you into rooms where people would insult your intelligence, where thieves would try to enlist you in your own robbery and disguise their burning and looting as Christian charity. But robbery is what this is, what it always was.

American reunion was built on a comfortable narrative that made enslavement into benevolence, white knights of body snatchers, and the mass slaughter of the war into a kind of sport in which one could conclude that both sides conducted their affairs with courage, honor, and élan. This lie of the Civil War is the lie of innocence, is the Dream.

I, like every kid I knew, loved The Dukes of Hazzard. But I would have done well to think more about why two outlaws, driving a car named the General Lee, must necessarily be portrayed as “just some good ole boys, never meanin’ no harm”—a mantra for the Dreamers if there ever was one. But what one “means” is neither important nor relevant. It is not necessary that you believe that the officer who choked Eric Garner set out that day to destroy a body. All you need to understand is that the officer carries with him the power of the American state and the weight of an American legacy, and they necessitate that of the bodies destroyed every year, some wild and disproportionate number of them will be black.

Here is what I would like for you to know: In America, it is traditional to destroy the black body—it is heritage. Enslavement was not merely the antiseptic borrowing of labor—it is not so easy to get a human being to commit their body against its own elemental interest. And so enslavement must be casual wrath and random manglings, the gashing of heads and brains blown out over the river as the body seeks to escape. It must be rape so regular as to be industrial. There is no uplifting way to say this.

It had to be blood. It had to be the thrashing of kitchen hands for the crime of churning butter at a leisurely clip. It had to be some woman “chear’d ... with thirty lashes a Saturday last and as many more a Tuesday again.” It could only be the employment of carriage whips, tongs, iron pokers, handsaws, stones, paperweights, or whatever might be handy to break the black body, the black family, the black community, the black nation. The bodies were pulverized into stock and marked with insurance. And the bodies were an aspiration, lucrative as Indian land, a veranda, a beautiful wife, or a summer home in the mountains. For the men who needed to believe themselves white, the bodies were the key to a social club, and the right to break the bodies was the mark of civilization.

“The two great divisions of society are not the rich and poor, but white and black,” said the great South Carolina senator John C. Calhoun. “And all the former, the poor as well as the rich, belong to the upper class, and are respected and treated as equals.” And there it is—the right to break the black body as the meaning of their sacred equality. And that right has always given them meaning, has always meant that there was someone down in the valley because a mountain is not a mountain if there is nothing below.

There is no them without you, and without the right to break you they must necessarily fall from the mountain, lose their divinity, and tumble out of the Dream. And then they would have to determine how to build their suburbs on something other than human bones, how to angle their jails toward something other than a human stockyard, how to erect a democracy independent of cannibalism. I would like to tell you that such a day approaches when the people who believe themselves to be white renounce this demon religion and begin to think of themselves as human. But I can see no real promise of such a day. We are captured, brother, surrounded by the majoritarian bandits of America. And this has happened here, in our only home, and the terrible truth is that we cannot will ourselves to an escape on our own.

I think now of the old rule that held that should a boy be set upon in someone else’s chancy hood, his friends must stand with him, and they must all take their beating together. I now know that within this edict lay the key to all living. None of us were promised to end the fight on our feet, fists raised to the sky. We could not control our enemies’ number, strength, or weaponry. Sometimes you just caught a bad one. But whether you fought or ran, you did it together, because that is the part that was in our control. What we must never do is willingly hand over our own bodies or the bodies of our friends. That was the wisdom: We knew we did not lay down the direction of the street, but despite that, we could—and must—fashion the way of our walk. And that is the deeper meaning of your name—that the struggle, in and of itself, has meaning.

I have raised you to respect every human being as singular, and you must extend that same respect into the past. Slavery is not an indefinable mass of flesh. It is a particular, specific enslaved woman, whose mind is as active as your own, whose range of feeling is as vast as your own; who prefers the way the light falls in one particular spot in the woods, who enjoys fishing where the water eddies in a nearby stream, who loves her mother in her own complicated way, thinks her sister talks too loud, has a favorite cousin, a favorite season, who excels at dressmaking and knows, inside herself, that she is as intelligent and capable as anyone. “Slavery” is this same woman born in a world that loudly proclaims its love of freedom and inscribes this love in its essential texts, a world in which these same professors hold this woman a slave, hold her mother a slave, her father a slave, her daughter a slave, and when this woman peers back into the generations all she sees is the enslaved. She can hope for more. She can imagine some future for her grandchildren. But when she dies, the world—which is really the only world she can ever know—ends. For this woman, enslavement is not a parable. It is damnation. It is the never-ending night. And the length of that night is most of our history. Never forget that we were enslaved in this country longer than we have been free. Never forget that for 250 years black people were born into chains—whole generations followed by more generations who knew nothing but chains.

You must resist the common urge toward the comforting narrative of divine law, toward fairy tales that imply some irrepressible justice. The enslaved were not bricks in your road, and their lives were not chapters in your redemptive history. They were people turned to fuel for the American machine. Enslavement was not destined to end, and it is wrong to claim our present circumstance—no matter how improved—as the redemption for the lives of people who never asked for the posthumous, untouchable glory of dying for their children. Our triumphs can never redeem this. Perhaps our triumphs are not even the point. Perhaps struggle is all we have

I am not a cynic. I love you, and I love the world, and I love it more with every new inch I discover. But you are a black boy, and you must be responsible for your body in a way that other boys cannot know. Indeed, you must be responsible for the worst actions of other black bodies, which, somehow, will always be assigned to you. And you must be responsible for the bodies of the powerful—the policeman who cracks you with a nightstick will quickly find his excuse in your furtive movements. You have to make your peace with the chaos, but you cannot lie.

“I could have you arrested,” he said. Which is to say: “One of your son’s earliest memories will be watching the men who sodomized Abner Louima and choked Anthony Baez cuff, club, tase, and break you.” I had forgotten the rules, an error as dangerous on the Upper West Side of Manhattan as on the West Side of Baltimore. One must be without error out here. Walk in single file. Work quietly. Pack an extra No. 2 pencil. Make no mistakes.

the price of error is higher for you than it is for your countrymen, and so that America might justify itself, the story of a black body’s destruction must always begin with his or her error, real or imagined—with Eric Garner’s anger, with Trayvon Martin’s mythical words (“You are gonna die tonight”), with Sean Bell’s mistake of running with the wrong crowd, with me standing too close to the small-eyed boy pulling out.

You are called to struggle, not because it assures you victory but because it assures you an honorable and sane life

I am sorry that I cannot save you—but not that sorry. Part of me thinks that your very vulnerability brings you closer to the meaning of life, just as for others, the quest to believe oneself white divides them from it. The fact is that despite their dreams, their lives are also not inviolable. When their own vulnerability becomes real—when the police decide that tactics intended for the ghetto should enjoy wider usage, when their armed society shoots down their children, when nature sends hurricanes against their cities—they are shocked by the rages of logic and the natural world in a way that those of us who were born and bred to understand cause and effect can never be.

I would not have you live like them. You have been cast into a race in which the wind is always at your face and the hounds are always at your heels. And to varying degrees this is true of all life. The difference is that you do not have the privilege of living in ignorance of this essential fact.

I never wanted you to be twice as good as them, so much as I have always wanted you to attack every day of your brief bright life determined to struggle. The people who must believe they are white can never be your measuring stick. I would not have you descend into your own dream. I would have you be a conscious citizen of this terrible and beautiful world.

Other polls also show black voters increasingly concerned about racism. White voters might be moving in the other direction, and philosophically seem to be deprioritizing the importance of diversity in favor of an embrace of capitalism, nationalism, and individual liberty

The majority of black and Hispanic people do think that speaking English is at least a somewhat important component of Americanness, but almost a tenth of both groups think it’s not important at al

black and Hispanic respondents are much more likely than whites to say that belief in God is a very important component of a specific American identity.

Seventy-six percent of white people and 74 percent of Hispanics think that civil liberties such as freedom of speech are very important pieces of American identity, while only 61 percent of black respondents feel so

More than half of black respondents think that a belief in capitalism isn’t a very important part of that identity, while good majorities of both white and Hispanic people think that it’s either somewhat important or very important

Forty-five percent of Hispanic respondents said that racial, ethnic, and religious diversity make the country much stronger, compared with 32 percent of whites

white respondents are most likely to say that diversity makes the country weaker, or to be ambivalent about the idea of diversity altogether.

the small but influential sliver of black conservatives who identify as Republican appears to be diminishing, as the increasing influence of Trumpism and the alt-right of the modern GOP have made the Republican Party more and more openly hostile to black voters.

Latino voters have increasingly made opposing the GOP agenda a top political priority in the age of President Donald Trump

40 percent of Hispanic respondents think that a potential citizenship question would be used for checking individuals’ immigration status as opposed to counting the population. Black respondents, on the other hand, are the least likely to buy the stated rationale for the question, and only 17 percent believe that it will be used for the sole purpose of counting the population

The profiles of the Republican and Democratic parties have shifted accordingl

In the 2018 midterm elections, Democrats elected one of the most racially diverse incoming classes of legislators since Reconstruction, and a diverse field of potential presidential contenders revolves around a multifaceted policy debate that’s heavily influenced by progressive ideas

Republicans have had to shape their party around explicit appeals to white voters and their anxieties, and have had to build an electoral strategy that can promote low overall turnout and stoke white grievances

In short, Democrats have cultivated an image as the party of racial and cultural pluralism, while Republicans have rejected pluralism as a viable strategy.

Majorities of both white and Hispanic respondents also favor the minimum-wage increase, but not at the numbers or with the fervor of black people

black and Hispanic respondents are also much more likely to strongly favor stricter gun-control laws than whites

black respondents are the most likely racial group to support providing pathways to citizenship for unauthorized immigrants currently living in the United States.

Six percent of black people and 7 percent of Hispanic people reported that they or someone else in their household did not have the proper voter identification the last time they went to vote, a small proportion but one much higher than the 1 percent of white respondents who said they’d had similar problems.

Nineteen percent of black people and 14 percent of Hispanic people said they’d had to wait in long lines, as opposed to 9 percent of whites

they come after a 2018 midterm election in which claims of voter suppression and major civil-rights lawsuits came to define elections in places such as Georgia, Kansas, and North Dakota.

A strong majority of white respondents—59 percent—think that speaking English is a very important part of being American.

These numbers track with the Census Bureau’s recent approximation that more than 600,000 households would fail to complete the census because of the question

these results from PRRI and The Atlantic shed new light on fundamental questions

They illustrate that the so-called demographic destiny of America is one that would look radically different should the country become majority nonwhite sometime in the next 20 or 30 years. The data indicate that white, black, and Hispanic voters have markedly divergent ideas on what exactly makes the American identity, and they also indicate that these differences are enforced and entrenched via spatial and social segregation

the data also cast some doubt on the political prospects of that demographic destiny. They show that black and Hispanic voters are more likely to be carved out of the political process, and that those efforts are perhaps aided by the existing regime of segregation

they show that the competing visions of America, as separated by race and region, are indeed competing, and that they are the chessboard upon which all politics is played.

Health officials, including Dr. Anthony Fauci, have said Trump's voice in promoting the vaccine would go far in convincing Republicans to get it.

Trump has made small efforts to promote the vaccine, including in a speech at this year's Conservative Political Action Conference, but he did not appear in a public service announcement featuring former presidents that was released last week.Psaki noted those presidents -- Barack Obama, George W. Bush, Bill Clinton and Jimmy Carter -- "did not need an engraved invitation" to promote the vaccine.

"The President's goal is to vaccine all Americans, not just those who voted for him," she said. "We know we need to meet everyone where they are, and that includes conservatives."

Mr Jones finds white evangelicals especially likely to express goodwill to African-Americans. But dig into their unconscious biases, he claims, and you see a different picture emerge. “In survey after survey” white Christians are much likelier than non-religious whites to express negative attitudes towards minorities and complacency about the rough treatment of African-Americans, among other indicators of racism.

Melding history, theology, statistical modelling and his own experience, as a Southern Baptist seminarian, Mr Jones suggests in “White Too Long” that white Christian traditions are so steeped in historic racism that “the norms of white supremacy have become deeply and broadly integrated into white Christian identity.”

Another explanation, argues a new book by Robert P. Jones, an authority on American religion and politics, and head of the Public Religion Research Institute, is that white Christians were especially receptive to Mr Trump’s race-baiting. Mr Jones also offers a grim theory for why this was the case.

Asked whether police killings of black men were isolated incidents, 71% of white evangelicals said they were, compared with 38% of non-religious whites.

white evangelicals are likely to be old, conservative and live in the South—characteristics that point to unreconstructed views on race independently of religion

two qualifiers are often added

Second, while people who simply identify as white evangelicals might hold such views, the most pious do not.

Mr Jones is unconvinced by either qualifier. He controls for age, partisanship and geography in his model—and finds the same pattern.

And he finds that practising evangelicals score the highest on his index of racism.

He concludes that white Christian identity is “independently predictive” of racist attitudes.

But, Mr Jones argues, the history of American Christianity makes this likelier than it might sound. The dominant southern strains of white evangelicalism were formed amid and sometimes in response to slavery.

Such claims are shocking.

The Southern Baptists, America’s biggest denomination, was launched to defend it biblically—which it did by representing black skin as the accursed “mark of Cain”. Many southern pastors were cheerleaders for the Confederacy, then shaped the culture of nostalgia and lament (the “religion of the lost cause”) that precluded a reckoning with Jim Crow’s legacy.

Post-war pessimism also led evangelicals to adopt a premillennialist theology, which viewed the world as irredeemable by man. Instead of wasting their time on social justice, it urged them to focus on their individual spirituality

The perverse effect, argues Mr Jones, was to imbue white evangelicals with “an unassailable sense of religious purity” that blinded them to their own behaviour.

As African-Americans fled north, mainstream protestants and Catholics increasingly adopted the mores of southern evangelicals.

The moral majority of the 1970s and 80s, fuelled by a Catholic aversion to abortion and common fears of the civil-rights movement, was the culmination of this fusion

Mr Jones’s model suggests the same racial attitudes are common to most white Christian traditions. Evangelicals are merely the most extreme case.

This troubling past was always the real mark of Cain, Mr Jones writes. And “today God’s anguished questions—‘Where is your brother?’ and ‘What have you done?’—still hang in the air like morning mist on the Mississippi River.

To Pollard, the Southern side had fought nobly for noble ends. “The war has left the South its own memories, its own heroes, its own tears, its own dead,” he wrote. “Under these traditions, sons will grow to manhood, and lessons sink deep that are learned from the lips of widowed mothers.” Pollard declared that a “‘war of ideas,’” a new war that “the South wants and insists upon perpetrating,” was now unfolding.

The South, Pollard wrote, “must wear the crown of thorns before she can assume that of victory.”

in “The Lost Cause Regained,” published in 1868. Pollard wrote that he was “profoundly convinced that the true cause fought for in the late war has not been ‘lost’ immeasurably or irrevocably, but is yet in a condition to be ‘regained’ by the South on ultimate issues of the political contest.” The issue was no longer slavery, but white supremacy, which Pollard described as the “true cause of the war” and the “true hope of the South.”

The Civil War, then, was to be fought perennially

And in many ways it unfolds still. The defiance of federal will from Reconstruction to our own day, the insistence on states’ rights in the face of the quest for racial justice and the revanchist reverence for Confederate emblems and figures are illuminated by engaging with the ethos of which Pollard so effectively wrote.

David W. Blight detailed how a white narrative of the war took hold, North and South, after Appomattox. As early as 1874 the historian William Wells Brown had said, “There is a feeling all over this country that the Negro has got about as much as he ought to have.”

In this recasting of reality, the Civil War was a family quarrel in which both sides were doing the best they could according to their lights.

White Americans chose to celebrate one another without reference to the actual causes and implications of the war. “The memory of slavery, emancipation and the 14th and 15th Amendments never fit well into a developing narrative in which the Old and New South were romanticized and welcomed back to a new nationalism,” Blight wrote, “and in which devotion alone made everyone right, and no one truly wrong

To recall that the war had been about what Lincoln had called a “new birth of freedom” meant acknowledging the nation’s failings on race. So white Americans decided to recall something else.

In such a view, it had all been a struggle between two reasonable parties over the nature of the Constitution; slavery was incidental

By minimizing race in the story of the war, white Americans felt free to minimize race not only in the past but in the present — leading, as Blight wrote, to “the denigration of Black dignity and the attempted erasure of emancipation from the national narrative of what the war had been about.”

in 1965, at a time when white Southerners were still deeply engaged in preserving Pollard’s Lost Cause, the editors of Ebony magazine published a special edition that became a book: “The White Problem in America.

“The problem of race in America, insofar as that problem is related to packets of melanin in men’s skins, is a white problem,” not a Black one, Lerone Bennett Jr., a historian and senior editor at Ebony, wrote in the volume’s opening essay. “And in order to solve that problem we must seek its source, not in the Negro but in the white American (in the process by which he was educated, in the needs and complexes he expresses through racism) and in the structure of the white community (in the power arrangements and the illicit uses of racism in the scramble for scarce values: power, prestige, income).”

King’s piece, “The Un-Christian Christian,” argued that white religious believers “too often … have responded to Christ emotionally, but they have not responded to His teachings morally.”

Baldwin closes the book by imagining the interior monologue of the white American who has been raised on the false history of the Lost Cause. “Do not blame me,” Baldwin wrote of the white “stammering” in his conscience. “I was not there. I did not do it. My history has nothing to do with Europe or the slave trade. Anyway, it was your chiefs who sold you to me.

on the same day … in the most private chamber of his heart always, he, the white man, remains proud of that history for which he does not wish to pay, and from which, materially, he has profited so much” — a history manipulated to make the unspeakable palatable.

He rose from a political party bent on thwarting demographic change by subverting the democratic process; a party whose base was addicted to white identity politics, steeped in religious fundamentalism, and suffused with authoritarian cravings—a party which, infected by Trumpism, now spreads the multiple malignancies metastasized by Trump’s personal and political pathologies.

Since the civil rights revolution triggered an influx of resentful Southern whites, the GOP has catered to white grievance and anxiety.

Trump’s transformative contribution has been to make racial antagonism overt—a badge of pride that bonds him to his followers in opposition to a pluralist democracy that threatens their imperiled social and political hegemony.

Take the poll released last week by the Public Religion Research Institute (PRRI) measuring the attitudes of “Fox News Republicans”—the 40 percent of party adherents who trust Fox as their primary source of TV news. The survey found that 91 percent oppose the Black Lives Matter movement; 90 percent believe that police killings of blacks are “isolated incidents”; and 58 think that whites are victimized by racial discrimination, compared to 36 percent who think blacks are.

He comprehends his audience all too well

Their animus toward immigration is equally strong. Substantial majorities believe that immigrants consume a disproportionate amount of governmental services, increase crime in local communities, and threaten our cultural and ethnic character.

In 2016, Vox reports, Trump carried whites by 54 to 39 percent; in 2020, by 57 to 42 percent (per the raw exit polls)

Another key subgroup of the GOP base, white evangelicals, harbors similar attitudes. The poll found that the majority adamantly disbelieve that the legacy of racial discrimination makes it difficult for African Americans to succeed

The head of the PRRI, Robert P. Jones, concludes that Trump arouses white Christians “not despite, but through appeals to white supremacy” based on evoking “powerful fears about the loss of White Christian dominance.”

That sense of racial and cultural besiegement pervades the 73 percent of Fox News Republicans who, the survey found, believe that white Christians suffer from “a lot” of societal discrimination—more than double the number who say that blacks do

Tucker Carlson serves as a cautionary tale. When Carlson dismissed, as gently as possible, the crackpot allegations of Trump lawyer Sidney Powell about a sweeping conspiracy using rogue voting machines, he was savaged across the right-wing echo chamber as a spineless quisling. Lesson learned.

fear of displacement helps explain the profound emotional connection between Trump and Republican voters. Their loyalty is not to the political philosophy traditionally embraced by the GOP, but a visceral sense of racial, religious, and cultural identity—and the need to preserve it—which is instinctively authoritarian and anti-democratic.

Bartels surveyed respondents regarding four statements which, taken together, read like a blueprint for Trump: The traditional American way of life is disappearing so fast that we may have to use force to save it. A time will come when patriotic Americans have to take the law into their own hands. Strong leaders sometimes have to bend the rules in order to get things done. It is hard to trust the results of elections when so many people will vote for anyone who offers a handout.

Support for Trump’s wall is nearly unanimous (96 percent); two-thirds (66 percent) favor barring refugees from entering the United States; and a majority (53 percent) support separating children from their parents when a family enters the country without permission.

This lies at the heart of Trump’s appeal: his shared sense of victimization by an insidious elite; his unvarnished denunciation of white America’s supposed enemies; and his promise to keep them at bay—if necessary, by force. For many in the Republican base, he fulfills a psychic longing for an American strongman.

In the New York Times, Katherine Stewart describes the growth of “a radical political ideology that is profoundly hostile to democracy and pluralism, and a certain political style that seeks to provoke moral panic, rewards the paranoid and views every partisan conflict as a conflagration, the end of the world.”

“Christian nationalism is a creation of a uniquely isolated messaging sphere. Many members of the rank and file get their main political information not just from messaging platforms that keep their audiences in a world that is divorced from reality, but also from dedicated religious networks and reactionary faith leaders.”

As Republican strategists well appreciate, a party whose appeal is confined to conservative whites is, over the demographic long term, doomed to defeat. The GOP’s design is to postpone as long as possible their electoral day of reckoning.

In launching his naked attempt to disenfranchise the majority of voters in Arizona, Georgia, Michigan, Pennsylvania, and Wisconsin through assertions of fraud unprecedented in their speciousness and scope, Trump took the GOP’s distaste for free and fair elections to its logical conclusion: the abrogation of American democracy at the highest level.

Trump justified his anti-democratic sociopathy by proliferating a plethora of groundless and preposterous falsehoods calculated to delegitimize our electoral processes. He claimed that millions of phony mail-in ballots had been cast for Biden; that voting machines had been re-engineered to exclude millions more cast for him; and that Republican election observers had been excluded from many polling places by a host of local officials bent on serving a labyrinthine conspiracy to purloin the White House.

Never once did he or his lawyers cite a shred of evidence supporting any material impropriety. Rather his purpose was to convince the Republican base that they were being cheated of their leader by the insidious “other.” Numerous polls confirm that it’s working; typical is a Politico/Morning Consult survey showing that 70 percent of Republicans don’t believe the election was fairly conducted.

As Trevor Potter, a Republican who formerly headed the Federal Election Commission, told the New York Times, Trump “is creating a road map to destabilization and chaos in future years. . . . What he’s saying, explicitly, is if a party doesn’t like the election result they have the right to change it by gaming the system.”

Reports Bump: “Most Republicans and Republican-leaning independents agreed with the first statement. . . . Nearly three-quarters agreed that election results should be treated with skepticism.” Republicans and Republican-leaning independents were also “significantly more likely to say they agreed with the other two statements than that they disagreed.”

Ultimately, this otherworldly obduracy stems from Trump’s manifest psychological illness: his imperishable narcissism; his ineradicable drive to be noticed; his relentless need to dominate; his comprehensive carelessness of all considerations save what pleases him in the moment. Television turned this moral pygmy into a mythic figure—and he cannot let go.

Republican elites want very much to turn the page on Donald Trump following his loss. But . . . they do not have any say in the matter, because their party now belongs to him. And the party belongs to Donald Trump because he has delivered to Republican voters exactly what they want.

a notable phenomenon of Trump’s presidency is the degree to which financially embattled working-class whites imagined, contrary to observable reality, that their economic situation had improved—or soon would. There are few better examples of how politics mirrors psychology more than lived experience.

This fidelity is why some Republican gurus remain committed to Trump’s strategy of maximizing support among middle-class and blue-collar whites. After all, they argue, despite Trump’s defeat the GOP did better than expected in senatorial and congressional races. Why risk tinkering with his formula?

Finally, economic populism is antithetical to the donor classes who, in truth, did better under Trump than did anyone else. They got their tax cuts and their judges—the GOP’s pipeline for judicial nominees, the Federalist Society, is dedicated to advancing pro-corporate jurisprudence. This is not the prescription for worker-friendly policies.

For the foreseeable future, Trumpism will define the GOP. The path to regeneration runs not through reform but, one fears, must proceed from self-destruction. The wait time will be painful for the party, and fateful for the country.

If the world had adopted the proposal widely endorsed at the end of the ’80s — a freezing of carbon emissions, with a reduction of 20 percent by 2005 — warming could have been held to less than 1.5 degrees.

Action had to be taken, and the United States would need to lead. It didn’t.

There can be no understanding of our current and future predicament without understanding why we failed to solve this problem when we had the chance.

The first suggestion to Rafe Pomerance that humankind was destroying the conditions necessary for its own survival came on Page 66 of the government publication EPA-600/7-78-019. It was a technical report about coal

‘This Is the Whole Banana’ Spring 1979

here was an urgent problem that demanded their attention, MacDonald believed, because human civilization faced an existential crisis. In “How to Wreck the Environment,” a 1968 essay published while he was a science adviser to Lyndon Johnson, MacDonald predicted a near future in which “nuclear weapons were effectively banned and the weapons of mass destruction were those of environmental catastrophe.” One of the most potentially devastating such weapons, he believed, was the gas that we exhaled with every breath: carbon dioxide. By vastly increasing carbon emissions, the world’s most advanced militaries could alter weather patterns and wreak famine, drought and economic collapse.

the Jasons. They were like one of those teams of superheroes with complementary powers that join forces in times of galactic crisis. They had been brought together by federal agencies, including the C.I.A, to devise scientific solutions to national-security problems: how to detect an incoming missile; how to predict fallout from a nuclear bomb; how to develop unconventional weapons, like plague-infested rats.

Agle pointed to an article about a prominent geophysicist named Gordon MacDonald, who was conducting a study on climate change with the Jasons, the mysterious coterie of elite scientists to which he belonged

During the spring of 1977 and the summer of 1978, the Jasons met to determine what would happen once the concentration of carbon dioxide in the atmosphere doubled from pre-Industrial Revolution levels. It was an arbitrary milestone, the doubling, but a useful one, as its inevitability was not in question; the threshold would most likely be breached by 2035.

The Jasons’ report to the Department of Energy, “The Long-Term Impact of Atmospheric Carbon Dioxide on Climate,” was written in an understated tone that only enhanced its nightmarish findings: Global temperatures would increase by an average of two to three degrees Celsius; Dust Bowl conditions would “threaten large areas of North America, Asia and Africa”; access to drinking water and agricultural production would fall, triggering mass migration on an unprecedented scale. “Perhaps the most ominous feature,” however, was the effect of a changing climate on the poles. Even a minimal warming “could lead to rapid melting” of the West Antarctic ice sheet. The ice sheet contained enough water to raise the level of the oceans 16 feet.

MacDonald explained that he first studied the carbon-dioxide issue when he was about Pomerance’s age — in 1961, when he served as an adviser to John F. Kennedy. Pomerance pieced together that MacDonald, in his youth, had been something of a prodigy: In his 20s, he advised Dwight D. Eisenhower on space exploration; at 32, he became a member of the National Academy of Sciences; at 40, he was appointed to the inaugural Council on Environmental Quality, where he advised Richard Nixon on the environmental dangers of burning coal. He monitored the carbon-dioxide problem the whole time, with increasing alarm.

They were surprised to learn how few senior officials were familiar with the Jasons’ findings, let alone understood the ramifications of global warming. At last, having worked their way up the federal hierarchy, the two went to see the president’s top scientist, Frank Press.

Thus began the Gordon and Rafe carbon-dioxide roadshow. Beginning in the spring of 1979, Pomerance arranged informal briefings with the E.P.A., the National Security Council, The New York Times, the Council on Environmental Quality and the Energy Department, which, Pomerance learned, had established an Office of Carbon Dioxide Effects two years earlier at MacDonald’s urging

. Out of respect for MacDonald, Press had summoned to their meeting what seemed to be the entire senior staff of the president’s Office of Science and Technology Policy — the officials consulted on every critical matter of energy and national security. What Pomerance had expected to be yet another casual briefing assumed the character of a high-level national-security meeting.

MacDonald would begin his presentation by going back more than a century to John Tyndall — an Irish physicist who was an early champion of Charles Darwin’s work and died after being accidentally poisoned by his wife. In 1859, Tyndall found that carbon dioxide absorbed heat and that variations in the composition of the atmosphere could create changes in climate. These findings inspired Svante Arrhenius, a Swedish chemist and future Nobel laureate, to deduce in 1896 that the combustion of coal and petroleum could raise global temperatures. This warming would become noticeable in a few centuries, Arrhenius calculated, or sooner if consumption of fossil fuels continued to increase.

Four decades later, a British steam engineer named Guy Stewart Callendar discovered that, at the weather stations he observed, the previous five years were the hottest in recorded history. Humankind, he wrote in a paper, had become “able to speed up the processes of Nature.” That was in 1939.

MacDonald’s history concluded with Roger Revelle, perhaps the most distinguished of the priestly caste of government scientists who, since the Manhattan Project, advised every president on major policy; he had been a close colleague of MacDonald and Press since they served together under Kennedy. In a 1957 paper written with Hans Suess, Revelle concluded that “human beings are now carrying out a large-scale geophysical experiment of a kind that could not have happened in the past nor be reproduced in the future.” Revelle helped the Weather Bureau establish a continuous measurement of atmospheric carbon dioxide at a site perched near the summit of Mauna Loa on the Big Island of Hawaii, 11,500 feet above the sea — a rare pristine natural laboratory on a planet blanketed by fossil-fuel emissions.

After nearly a decade of observation, Revelle had shared his concerns with Lyndon Johnson, who included them in a special message to Congress two weeks after his inauguration. Johnson explained that his generation had “altered the composition of the atmosphere on a global scale” through the burning of fossil fuels, and his administration commissioned a study of the subject by his Science Advisory Committee. Revelle was its chairman, and its 1965 executive report on carbon dioxide warned of the rapid melting of Antarctica, rising seas, increased acidity of fresh waters — changes that would require no less than a coordinated global effort to forestall.Yet emissions continued to rise, and at this rate, MacDonald warned, they could see a snowless New England, the swamping of major coastal cities, as much as a 40 percent decline in national wheat production, the forced migration of about one-quarter of the world’s population. Not within centuries — within their own lifetimes.

On May 22, Press wrote a letter to the president of the National Academy of Sciences requesting a full assessment of the carbon-dioxide issue. Jule Charney, the father of modern meteorology, would gather the nation’s top oceanographers, atmospheric scientists and climate modelers to judge whether MacDonald’s alarm was justified — whether the world was, in fact, headed to cataclysm.

If Charney’s group confirmed that the world was careering toward an existential crisis, the president would be forced to act.

Hansen turned from the moon to Venus. Why, he tried to determine, was its surface so hot? In 1967, a Soviet satellite beamed back the answer: The planet’s atmosphere was mainly carbon dioxide. Though once it may have had habitable temperatures, it was believed to have succumbed to a runaway greenhouse effect: As the sun grew brighter, Venus’s ocean began to evaporate, thickening the atmosphere, which forced yet greater evaporation — a self-perpetuating cycle that finally boiled off the ocean entirely and heated the planet’s surface to more than 800 degrees Fahrenheit

At the other extreme, Mars’s thin atmosphere had insufficient carbon dioxide to trap much heat at all, leaving it about 900 degrees colder. Earth lay in the middle, its Goldilocks greenhouse effect just strong enough to support life.

We want to learn more about Earth’s climate, Jim told Anniek — and how humanity can influence it. He would use giant new supercomputers to map the planet’s atmosphere. They would create Mirror Worlds: parallel realities that mimicked our own. These digital simulacra, technically called “general circulation models,” combined the mathematical formulas that governed the behavior of the sea, land and sky into a single computer model. Unlike the real world, they could be sped forward to reveal the future.

The government officials, many of them scientists themselves, tried to suppress their awe of the legends in their presence: Henry Stommel, the world’s leading oceanographer; his protégé, Carl Wunsch, a Jason; the Manhattan Project alumnus Cecil Leith; the Harvard planetary physicist Richard Goody. These were the men who, in the last three decades, had discovered foundational principles underlying the relationships among sun, atmosphere, land and ocean — which is to say, the climate.

When, at Charney’s request, Hansen programmed his model to consider a future of doubled carbon dioxide, it predicted a temperature increase of four degrees Celsius. That was twice as much warming as the prediction made by the most prominent climate modeler, Syukuro Manabe, whose government lab at Princeton was the first to model the greenhouse effect. The difference between the two predictions — between warming of two degrees Celsius and four degrees Celsius — was the difference between damaged coral reefs and no reefs whatsoever, between thinning forests and forests enveloped by desert, between catastrophe and chaos.

The discrepancy between the models, Arakawa concluded, came down to ice and snow. The whiteness of the world’s snowfields reflected light; if snow melted in a warmer climate, less radiation would escape the atmosphere, leading to even greater warming. Shortly before dawn, Arakawa concluded that Manabe had given too little weight to the influence of melting sea ice, while Hansen had overemphasized it. The best estimate lay in between. Which meant that the Jasons’ calculation was too optimistic. When carbon dioxide doubled in 2035 or thereabouts, global temperatures would increase between 1.5 and 4.5 degrees Celsius, with the most likely outcome a warming of three degrees.

within the highest levels of the federal government, the scientific community and the oil-and-gas industry — within the commonwealth of people who had begun to concern themselves with the future habitability of the planet — the Charney report would come to have the authority of settled fact. It was the summation of all the predictions that had come before, and it would withstand the scrutiny of the decades that followed it. Charney’s group had considered everything known about ocean, sun, sea, air and fossil fuels and had distilled it to a single number: three. When the doubling threshold was broached, as appeared inevitable, the world would warm three degrees Celsius

The last time the world was three degrees warmer was during the Pliocene, three million years ago, when beech trees grew in Antarctica, the seas were 80 feet higher and horses galloped across the Canadian coast of the Arctic Ocean.

After the publication of the Charney report, Exxon decided to create its own dedicated carbon-dioxide research program, with an annual budget of $600,000. Only Exxon was asking a slightly different question than Jule Charney. Exxon didn’t concern itself primarily with how much the world would warm. It wanted to know how much of the warming Exxon could be blamed for.

“It behooves us to start a very aggressive defensive program,” Shaw wrote in a memo to a manager, “because there is a good probability that legislation affecting our business will be passed.”

Shaw turned to Wallace Broecker, a Columbia University oceanographer who was the second author of Roger Revelle’s 1965 carbon-dioxide report for Lyndon Johnson. In 1977, in a presentation at the American Geophysical Union, Broecker predicted that fossil fuels would have to be restricted, whether by taxation or fiat. More recently, he had testified before Congress, calling carbon dioxide “the No.1 long-term environmental problem.” If presidents and senators trusted Broecker to tell them the bad news, he was good enough for Exxon.

The company had been studying the carbon-dioxide problem for decades, since before it changed its name to Exxon. In 1957, scientists from Humble Oil published a study tracking “the enormous quantity of carbon dioxide” contributed to the atmosphere since the Industrial Revolution “from the combustion of fossil fuels.” Even then, the observation that burning fossil fuels had increased the concentration of carbon in the atmosphere was well understood and accepted by Humble’s scientists.

The American Petroleum Institute, the industry’s largest trade association, asked the same question in 1958 through its air-pollution study group and replicated the findings made by Humble Oil. So did another A.P.I. study conducted by the Stanford Research Institute a decade later, in 1968, which concluded that the burning of fossil fuels would bring “significant temperature changes” by the year 2000 and ultimately “serious worldwide environmental changes,” including the melting of the Antarctic ice cap and rising seas.

The ritual repeated itself every few years. Industry scientists, at the behest of their corporate bosses, reviewed the problem and found good reasons for alarm and better excuses to do nothing. Why should they act when almost nobody within the United States government — nor, for that matter, within the environmental movement — seemed worried?

Why take on an intractable problem that would not be detected until this generation of employees was safely retired? Worse, the solutions seemed more punitive than the problem itself. Historically, energy use had correlated to economic growth — the more fossil fuels we burned, the better our lives became. Why mess with that?

That June, Jimmy Carter signed the Energy Security Act of 1980, which directed the National Academy of Sciences to start a multiyear, comprehensive study, to be called “Changing Climate,” that would analyze social and economic effects of climate change. More urgent, the National Commission on Air Quality, at the request of Congress, invited two dozen experts, including Henry Shaw himself, to a meeting in Florida to propose climate policy.

On April 3, 1980, Senator Paul Tsongas, a Massachusetts Democrat, held the first congressional hearing on carbon-dioxide buildup in the atmosphere. Gordon MacDonald testified that the United States should “take the initiative” and develop, through the United Nations, a way to coordinate every nation’s energy policies to address the problem.

During the expansion of the Clean Air Act, he pushed for the creation of the National Commission on Air Quality, charged with ensuring that the goals of the act were being met. One such goal was a stable global climate. The Charney report had made clear that goal was not being met, and now the commission wanted to hear proposals for legislation. It was a profound responsibility, and the two dozen experts invited to the Pink Palace — policy gurus, deep thinkers, an industry scientist and an environmental activist — had only three days to achieve it, but the utopian setting made everything seem possible

We have less time than we realize, said an M.I.T. nuclear engineer named David Rose, who studied how civilizations responded to large technological crises. “People leave their problems until the 11th hour, the 59th minute,” he said. “And then: ‘Eloi, Eloi, Lama Sabachthani?’ ” — “My God, my God, why hast thou forsaken me?”

The attendees seemed to share a sincere interest in finding solutions. They agreed that some kind of international treaty would ultimately be needed to keep atmospheric carbon dioxide at a safe level. But nobody could agree on what that level was.

William Elliott, a NOAA scientist, introduced some hard facts: If the United States stopped burning carbon that year, it would delay the arrival of the doubling threshold by only five years. If Western nations somehow managed to stabilize emissions, it would forestall the inevitable by only eight years. The only way to avoid the worst was to stop burning coal. Yet China, the Soviet Union and the United States, by far the world’s three largest coal producers, were frantically accelerating extraction.

“Do we have a problem?” asked Anthony Scoville, a congressional science consultant. “We do, but it is not the atmospheric problem. It is the political problem.” He doubted that any scientific report, no matter how ominous its predictions, would persuade politicians to act.

The talk of ending oil production stirred for the first time the gentleman from Exxon. “I think there is a transition period,” Henry Shaw said. “We are not going to stop burning fossil fuels and start looking toward solar or nuclear fusion and so on. We are going to have a very orderly transition from fossil fuels to renewable energy sources.”

What if the problem was that they were thinking of it as a problem? “What I am saying,” Scoville continued, “is that in a sense we are making a transition not only in energy but the economy as a whole.” Even if the coal and oil industries collapsed, renewable technologies like solar energy would take their place. Jimmy Carter was planning to invest $80 billion in synthetic fuel. “My God,” Scoville said, “with $80 billion, you could have a photovoltaics industry going that would obviate the need for synfuels forever!”

nobody could agree what to do. John Perry, a meteorologist who had worked as a staff member on the Charney report, suggested that American energy policy merely “take into account” the risks of global warming, though he acknowledged that a nonbinding measure might seem “intolerably stodgy.” “It is so weak,” Pomerance said, the air seeping out of him, “as to not get us anywhere.”

Scoville pointed out that the United States was responsible for the largest share of global carbon emissions. But not for long. “If we’re going to exercise leadership,” he said, “the opportunity is now.

One way to lead, he proposed, would be to classify carbon dioxide as a pollutant under the Clean Air Act and regulate it as such. This was received by the room like a belch. By Scoville’s logic, every sigh was an act of pollution. Did the science really support such an extreme measure? The Charney report did exactly that, Pomerance said.

Slade, the director of the Energy Department’s carbon-dioxide program, considered the lag a saving grace. If changes did not occur for a decade or more, he said, those in the room couldn’t be blamed for failing to prevent them. So what was the problem?

“Call it whatever.” Besides, Pomerance added, they didn’t have to ban coal tomorrow. A pair of modest steps could be taken immediately to show the world that the United States was serious: the implementation of a carbon tax and increased investment in renewable energy. Then the United States could organize an international summit meeting to address climate change

these two dozen experts, who agreed on the major points and had made a commitment to Congress, could not draft a single paragraph. Hours passed in a hell of fruitless negotiation, self-defeating proposals and impulsive speechifying. Pomerance and Scoville pushed to include a statement calling for the United States to “sharply accelerate international dialogue,” but they were sunk by objections and caveats.

They never got to policy proposals. They never got to the second paragraph. The final statement was signed by only the moderator, who phrased it more weakly than the declaration calling for the workshop in the first place. “The guide I would suggest,” Jorling wrote, “is whether we know enough not to recommend changes in existing policy.”

Pomerance had seen enough. A consensus-based strategy would not work — could not work — without American leadership. And the United States wouldn’t act unless a strong leader persuaded it to do so — someone who would speak with authority about the science, demand action from those in power and risk everything in pursuit of justice.

The meeting ended Friday morning. On Tuesday, four days later, Ronald Reagan was elected president.

‘Otherwise, They’ll Gurgle’ November 1980-September 1981

In the midst of this carnage, the Council on Environmental Quality submitted a report to the White House warning that fossil fuels could “permanently and disastrously” alter Earth’s atmosphere, leading to “a warming of the Earth, possibly with very serious effects.” Reagan did not act on the council’s advice. Instead, his administration considered eliminating the council.

After the election, Reagan considered plans to close the Energy Department, increase coal production on federal land and deregulate surface coal mining. Once in office, he appointed James Watt, the president of a legal firm that fought to open public lands to mining and drilling, to run the Interior Department. “We’re deliriously happy,” the president of the National Coal Association was reported to have said. Reagan preserved the E.P.A. but named as its administrator Anne Gorsuch, an anti-regulation zealot who proceeded to cut the agency’s staff and budget by about a quarter

Reagan “has declared open war on solar energy,” the director of the nation’s lead solar-energy research agency said, after he was asked to resign). Reagan appeared determined to reverse the environmental achievements of Jimmy Carter, before undoing those of Richard Nixon, Lyndon Johnson, John F. Kennedy and, if he could get away with it, Theodore Roosevelt.

When Reagan considered closing the Council on Environmental Quality, its acting chairman, Malcolm Forbes Baldwin, wrote to the vice president and the White House chief of staff begging them to reconsider; in a major speech the same week, “A Conservative’s Program for the Environment,” Baldwin argued that it was “time for today’s conservatives explicitly to embrace environmentalism.” Environmental protection was not only good sense. It was good business. What could be more conservative than an efficient use of resources that led to fewer federal subsidies?

Meanwhile the Charney report continued to vibrate at the periphery of public consciousness. Its conclusions were confirmed by major studies from the Aspen Institute, the International Institute for Applied Systems Analysis near Vienna and the American Association for the Advancement of Science. Every month or so, nationally syndicated articles appeared summoning apocalypse: “Another Warning on ‘Greenhouse Effect,’ ” “Global Warming Trend ‘Beyond Human Experience,’ ” “Warming Trend Could ‘Pit Nation Against Nation.’

Pomerance read on the front page of The New York Times on Aug. 22, 1981, about a forthcoming paper in Science by a team of seven NASA scientists. They had found that the world had already warmed in the past century. Temperatures hadn’t increased beyond the range of historical averages, but the scientists predicted that the warming signal would emerge from the noise of routine weather fluctuations much sooner than previously expected. Most unusual of all, the paper ended with a policy recommendation: In the coming decades, the authors wrote, humankind should develop alternative sources of energy and use fossil fuels only “as necessary.” The lead author was James Hansen.

Pomerance listened and watched. He understood Hansen’s basic findings well enough: Earth had been warming since 1880, and the warming would reach “almost unprecedented magnitude” in the next century, leading to the familiar suite of terrors, including the flooding of a 10th of New Jersey and a quarter of Louisiana and Florida. But Pomerance was excited to find that Hansen could translate the complexities of atmospheric science into plain English.

7. ‘We’re All Going to Be the Victims’ March 1982

Gore had learned about climate change a dozen years earlier as an undergraduate at Harvard, when he took a class taught by Roger Revelle. Humankind was on the brink of radically transforming the global atmosphere, Revelle explained, drawing Keeling’s rising zigzag on the blackboard, and risked bringing about the collapse of civilization. Gore was stunned: Why wasn’t anyone talking about this?

Most in Congress considered the science committee a legislative backwater, if they considered it at all; this made Gore’s subcommittee, which had no legislative authority, an afterthought to an afterthought. That, Gore vowed, would change. Environmental and health stories had all the elements of narrative drama: villains, victims and heroes. In a hearing, you could summon all three, with the chairman serving as narrator, chorus and moral authority. He told his staff director that he wanted to hold a hearing every week.

The Revelle hearing went as Grumbly had predicted. The urgency of the issue was lost on Gore’s older colleagues, who drifted in and out while the witnesses testified. There were few people left by the time the Brookings Institution economist Lester Lave warned that humankind’s profligate exploitation of fossil fuels posed an existential test to human nature. “Carbon dioxide stands as a symbol now of our willingness to confront the future,” he said. “It will be a sad day when we decide that we just don’t have the time or thoughtfulness to address those issues.”

That night, the news programs featured the resolution of the baseball strike, the ongoing budgetary debate and the national surplus of butter.

There emerged, despite the general comity, a partisan divide. Unlike the Democrats, the Republicans demanded action. “Today I have a sense of déjà vu,” said Robert Walker, a Republican from Pennsylvania. In each of the last five years, he said, “we have been told and told and told that there is a problem with the increasing carbon dioxide in the atmosphere. We all accept that fact, and we realize that the potential consequences are certainly major in their impact on mankind.” Yet they had failed to propose a single law. “Now is the time,” he said. “The research is clear. It is up to us now to summon the political will.”

Hansen flew to Washington to testify on March 25, 1982, performing before a gallery even more thinly populated than at Gore’s first hearing on the greenhouse effect. Gore began by attacking the Reagan administration for cutting funding for carbon-dioxide research despite the “broad consensus in the scientific community that the greenhouse effect is a reality.” William Carney, a Republican from New York, bemoaned the burning of fossil fuels and argued passionately that science should serve as the basis for legislative policy

the experts invited by Gore agreed with the Republicans: The science was certain enough. Melvin Calvin, a Berkeley chemist who won the Nobel Prize for his work on the carbon cycle, said that it was useless to wait for stronger evidence of warming. “You cannot do a thing about it when the signals are so big that they come out of the noise,” he said. “You have to look for early warning signs.”

Hansen’s job was to share the warning signs, to translate the data into plain English. He explained a few discoveries that his team had made — not with computer models but in libraries. By analyzing records from hundreds of weather stations, he found that the surface temperature of the planet had already increased four-tenths of a degree Celsius in the previous century. Data from several hundred tide-gauge stations showed that the oceans had risen four inches since the 1880s

It occurred to Hansen that this was the only political question that mattered: How long until the worst began? It was not a question on which geophysicists expended much effort; the difference between five years and 50 years in the future was meaningless in geologic time. Politicians were capable of thinking only in terms of electoral time: six years, four years, two years. But when it came to the carbon problem, the two time schemes were converging.

“Within 10 or 20 years,” Hansen said, “we will see climate changes which are clearly larger than the natural variability.” James Scheuer wanted to make sure he understood this correctly. No one else had predicted that the signal would emerge that quickly. “If it were one or two degrees per century,” he said, “that would be within the range of human adaptability. But we are pushing beyond the range of human adaptability.” “Yes,” Hansen said.

How soon, Scheuer asked, would they have to change the national model of energy production? Hansen hesitated — it wasn’t a scientific question. But he couldn’t help himself. He had been irritated, during the hearing, by all the ludicrous talk about the possibility of growing more trees to offset emissions. False hopes were worse than no hope at all: They undermined the prospect of developing real solutions. “That time is very soon,” Hansen said finally. “My opinion is that it is past,” Calvin said, but he was not heard because he spoke from his seat. He was told to speak into the microphone. “It is already later,” Calvin said, “than you think.”

From Gore’s perspective, the hearing was an unequivocal success. That night Dan Rather devoted three minutes of “CBS Evening News” to the greenhouse effect. A correspondent explained that temperatures had increased over the previous century, great sheets of pack ice in Antarctica were rapidly melting, the seas were rising; Calvin said that “the trend is all in the direction of an impending catastrophe”; and Gore mocked Reagan for his shortsightedness. Later, Gore could take credit for protecting the Energy Department’s carbon-dioxide program, which in the end was largely preserved.

8. ‘The Direction of an Impending Catastrophe’ 1982

Following Henry Shaw’s recommendation to establish credibility ahead of any future legislative battles, Exxon had begun to spend conspicuously on global-warming research. It donated tens of thousands of dollars to some of the most prominent research efforts, including one at Woods Hole led by the ecologist George Woodwell, who had been calling for major climate policy as early as the mid-1970s, and an international effort coordinated by the United Nations. Now Shaw offered to fund the October 1982 symposium on climate change at Columbia’s Lamont-Doherty campus.

David boasted that Exxon would usher in a new global energy system to save the planet from the ravages of climate change. He went so far as to argue that capitalism’s blind faith in the wisdom of the free market was “less than satisfying” when it came to the greenhouse effect. Ethical considerations were necessary, too. He pledged that Exxon would revise its corporate strategy to account for climate change, even if it were not “fashionable” to do so. As Exxon had already made heavy investments in nuclear and solar technology, he was “generally upbeat” that Exxon would “invent” a future of renewable energy.

Hansen had reason to feel upbeat himself. If the world’s largest oil-and-gas company supported a new national energy model, the White House would not stand in its way. The Reagan administration was hostile to change from within its ranks. But it couldn’t be hostile to Exxon.

The carbon-dioxide issue was beginning to receive major national attention — Hansen’s own findings had become front-page news, after all. What started as a scientific story was turning into a political story.

The political realm was itself a kind of Mirror World, a parallel reality that crudely mimicked our own. It shared many of our most fundamental laws, like the laws of gravity and inertia and publicity. And if you applied enough pressure, the Mirror World of politics could be sped forward to reveal a new future. Hansen was beginning to understand that too.

1. ‘Caution, Not Panic’ 1983-1984

in the fall of 1983, the climate issue entered an especially long, dark winter. And all because of a single report that had done nothing to change the state of climate science but transformed the state of climate politics.

After the publication of the Charney report in 1979, Jimmy Carter had directed the National Academy of Sciences to prepare a comprehensive, $1 million analysis of the carbon-dioxide problem: a Warren Commission for the greenhouse effect. A team of scientist-dignitaries — among them Revelle, the Princeton modeler Syukuro Manabe and the Harvard political economist Thomas Schelling, one of the intellectual architects of Cold War game theory — would review the literature, evaluate the consequences of global warming for the world order and propose remedies

Then Reagan won the White House.

the incipient report served as the Reagan administration’s answer to every question on the subject. There could be no climate policy, Fred Koomanoff and his associates said, until the academy ruled. In the Mirror World of the Reagan administration, the warming problem hadn’t been abandoned at all. A careful, comprehensive solution was being devised. Everyone just had to wait for the academy’s elders to explain what it was.

The committee’s chairman, William Nierenberg — a Jason, presidential adviser and director of Scripps, the nation’s pre-eminent oceanographic institution — argued that action had to be taken immediately, before all the details could be known with certainty, or else it would be too late.

Better to bet on American ingenuity to save the day. Major interventions in national energy policy, taken immediately, might end up being more expensive, and less effective, than actions taken decades in the future, after more was understood about the economic and social consequences of a warmer planet. Yes, the climate would change, mostly for the worst, but future generations would be better equipped to change with it.

Government officials who knew Nierenberg were not surprised by his conclusions: He was an optimist by training and experience, a devout believer in the doctrine of American exceptionalism, one of the elite class of scientists who had helped the nation win a global war, invent the most deadly weapon conceivable and create the booming aerospace and computer industries. America had solved every existential problem it had confronted over the previous generation; it would not be daunted by an excess of carbon dioxide. Nierenberg had also served on Reagan’s transition team. Nobody believed that he had been directly influenced by his political connections, but his views — optimistic about the saving graces of market forces, pessimistic about the value of government regulation — reflected all the ardor of his party.

That’s what Nierenberg wrote in “Changing Climate.” But it’s not what he said in the press interviews that followed. He argued the opposite: There was no urgent need for action. The public should not entertain the most “extreme negative speculations” about climate change (despite the fact that many of those speculations appeared in his report). Though “Changing Climate” urged an accelerated transition to renewable fuels, noting that it would take thousands of years for the atmosphere to recover from the damage of the last century, Nierenberg recommended “caution, not panic.” Better to wait and see

The damage of “Changing Climate” was squared by the amount of attention it received. Nierenberg’s speech in the Great Hall, being one-500th the length of the actual assessment, received 500 times the press coverage. As The Wall Street Journal put it, in a line echoed by trade journals across the nation: “A panel of top scientists has some advice for people worried about the much-publicized warming of the Earth’s climate: You can cope.”

On “CBS Evening News,” Dan Rather said the academy had given “a cold shoulder” to a grim, 200-page E.P.A. assessment published earlier that week (titled “Can We Delay a Greenhouse Warming?”; the E.P.A.’s answer, reduced to a word, was no). The Washington Post described the two reports, taken together, as “clarion calls to inaction.

George Keyworth II, Reagan’s science adviser. Keyworth used Nierenberg’s optimism as reason to discount the E.P.A.’s “unwarranted and unnecessarily alarmist” report and warned against taking any “near-term corrective action” on global warming. Just in case it wasn’t clear, Keyworth added, “there are no actions recommended other than continued research.”

Edward David Jr., two years removed from boasting of Exxon’s commitment to transforming global energy policy, told Science that the corporation had reconsidered. “Exxon has reverted to being mainly a supplier of conventional hydrocarbon fuels — petroleum products, natural gas and steam coal,” David said. The American Petroleum Institute canceled its own carbon-dioxide research program, too.

Exxon soon revised its position on climate-change research. In a presentation at an industry conference, Henry Shaw cited “Changing Climate” as evidence that “the general consensus is that society has sufficient time to technologically adapt to a CO₂ greenhouse effect.” If the academy had concluded that regulations were not a serious option, why should Exxon protest

2. ‘You Scientists Win’ 1985

3. The Size of The Human Imagination Spring-Summer 1986

Curtis Moore’s proposal: Use ozone to revive climate. The ozone hole had a solution — an international treaty, already in negotiation. Why not hitch the milk wagon to the bullet train? Pomerance was skeptical. The problems were related, sure: Without a reduction in CFC emissions, you didn’t have a chance of averting cataclysmic global warming. But it had been difficult enough to explain the carbon issue to politicians and journalists; why complicate the sales pitch? Then again, he didn’t see what choice he had. The Republicans controlled the Senate, and Moore was his connection to the Senate’s environmental committee.

Pomerance met with Senator John Chafee, a Republican from Rhode Island, and helped persuade him to hold a double-barreled hearing on the twin problems of ozone and carbon dioxide on June 10 and 11, 1986

F.Sherwood Rowland, Robert Watson, a NASA scientist, and Richard Benedick, the administration’s lead representative in international ozone negotiations, would discuss ozone; James Hansen, Al Gore, the ecologist George Woodwell and Carl Wunsch, a veteran of the Charney group, would testify about climate change.

As Pomerance had hoped, fear about the ozone layer ensured a bounty of press coverage for the climate-change testimony. But as he had feared, it caused many people to conflate the two crises. One was Peter Jennings, who aired the video on ABC’s “World News Tonight,” warning that the ozone hole “could lead to flooding all over the world, also to drought and to famine.”

The confusion helped: For the first time since the “Changing Climate” report, global-warming headlines appeared by the dozen. William Nierenberg’s “caution, not panic” line was inverted. It was all panic without a hint of caution: “A Dire Forecast for ‘Greenhouse’ Earth” (the front page of The Washington Post); “Scientists Predict Catastrophes in Growing Global Heat Wave” (Chicago Tribune); “Swifter Warming of Globe Foreseen” (The New York Times).

After three years of backsliding and silence, Pomerance was exhilarated to see interest in the issue spike overnight. Not only that: A solution materialized, and a moral argument was passionately articulated — by Rhode Island’s Republican senator no less. “Ozone depletion and the greenhouse effect can no longer be treated solely as important scientific questions,” Chafee said. “They must be seen as critical problems facing the nations of the world, and they are problems that demand solutions.”

The old canard about the need for more research was roundly mocked — by Woodwell, by a W.R.I. colleague named Andrew Maguire, by Senator George Mitchell, a Democrat from Maine. “Scientists are never 100 percent certain,” the Princeton historian Theodore Rabb testified. “That notion of total certainty is something too elusive ever to be sought.” As Pomerance had been saying since 1979, it was past time to act. Only now the argument was so broadly accepted that nobody dared object.

The ozone hole, Pomerance realized, had moved the public because, though it was no more visible than global warming, people could be made to see it. They could watch it grow on video. Its metaphors were emotionally wrought: Instead of summoning a glass building that sheltered plants from chilly weather (“Everything seems to flourish in there”), the hole evoked a violent rending of the firmament, inviting deathly radiation. Americans felt that their lives were in danger. An abstract, atmospheric problem had been reduced to the size of the human imagination. It had been made just small enough, and just large enough, to break through.

Four years after “Changing Climate,” two years after a hole had torn open the firmament and a month after the United States and more than three dozen other nations signed a treaty to limit use of CFCs, the climate-change corps was ready to celebrate. It had become conventional wisdom that climate change would follow ozone’s trajectory. Reagan’s E.P.A. administrator, Lee M. Thomas, said as much the day he signed the Montreal Protocol on Substances That Deplete the Ozone Layer (the successor to the Vienna Convention), telling reporters that global warming was likely to be the subject of a future international agreement

Congress had already begun to consider policy — in 1987 alone, there were eight days of climate hearings, in three committees, across both chambers of Congress; Senator Joe Biden, a Delaware Democrat, had introduced legislation to establish a national climate-change strategy. And so it was that Jim Hansen found himself on Oct. 27 in the not especially distinguished ballroom of the Quality Inn on New Jersey Avenue, a block from the Capitol, at “Preparing for Climate Change,” which was technically a conference but felt more like a wedding.

John Topping was an old-line Rockefeller Republican, a Commerce Department lawyer under Nixon and an E.P.A. official under Reagan. He first heard about the climate problem in the halls of the E.P.A. in 1982 and sought out Hansen, who gave him a personal tutorial. Topping was amazed to discover that out of the E.P.A.’s 13,000-person staff, only seven people, by his count, were assigned to work on climate, though he figured it was more important to the long-term security of the nation than every other environmental issue combined.

Glancing around the room, Jim Hansen could chart, like an arborist counting rings on a stump, the growth of the climate issue over the decade. Veterans like Gordon MacDonald, George Woodwell and the environmental biologist Stephen Schneider stood at the center of things. Former and current staff members from the congressional science committees (Tom Grumbly, Curtis Moore, Anthony Scoville) made introductions to the congressmen they advised. Hansen’s owlish nemesis Fred Koomanoff was present, as were his counterparts from the Soviet Union and Western Europe. Rafe Pomerance’s cranium could be seen above the crowd, but unusually he was surrounded by colleagues from other environmental organizations that until now had shown little interest in a diffuse problem with no proven fund-raising record. The party’s most conspicuous newcomers, however, the outermost ring, were the oil-and-gas executives.

That evening, as a storm spat and coughed outside, Rafe Pomerance gave one of his exhortative speeches urging cooperation among the various factions, and John Chafee and Roger Revelle received awards; introductions were made and business cards earnestly exchanged. Not even a presentation by Hansen of his research could sour the mood. The next night, on Oct. 28, at a high-spirited dinner party in Topping’s townhouse on Capitol Hill, the oil-and-gas men joked with the environmentalists, the trade-group representatives chatted up the regulators and the academics got merrily drunk. Mikhail Budyko, the don of the Soviet climatologists, settled into an extended conversation about global warming with Topping’s 10-year-old son. It all seemed like the start of a grand bargain, a uniting of factions — a solution.

Hansen was accustomed to the bureaucratic nuisances that attended testifying before Congress; before a hearing, he had to send his formal statement to NASA headquarters, which forwarded it to the White House’s Office of Management and Budget for approval. “Major greenhouse climate changes are a certainty,” he had written. “By the 2010s [in every scenario], essentially the entire globe has very substantial warming.”

By all appearances, plans for major policy continued to advance rapidly. After the Johnston hearing, Timothy Wirth, a freshman Democratic senator from Colorado on the energy committee, began to plan a comprehensive package of climate-change legislation — a New Deal for global warming. Wirth asked a legislative assistant, David Harwood, to consult with experts on the issue, beginning with Rafe Pomerance, in the hope of converting the science of climate change into a new national energy policy.

In March 1988, Wirth joined 41 other senators, nearly half of them Republicans, to demand that Reagan call for an international treaty modeled after the ozone agreement. Because the United States and the Soviet Union were the world’s two largest contributors of carbon emissions, responsible for about one-third of the world total, they should lead the negotiations. Reagan agreed. In May, he signed a joint statement with Mikhail Gorbachev that included a pledge to cooperate on global warming.

Al Gore himself had, for the moment, withdrawn his political claim to the issue. In 1987, at the age of 39, Gore announced that he was running for president, in part to bring attention to global warming, but he stopped emphasizing it after the subject failed to captivate New Hampshire primary voters.

5. ‘You Will See Things That You Shall Believe’ Summer 1988

It was the hottest and driest summer in history. Everywhere you looked, something was bursting into flames. Two million acres in Alaska incinerated, and dozens of major fires scored the West. Yellowstone National Park lost nearly one million acres. Smoke was visible from Chicago, 1,600 miles away.

In Nebraska, suffering its worst drought since the Dust Bowl, there were days when every weather station registered temperatures above 100 degrees. The director of the Kansas Department of Health and Environment warned that the drought might be the dawning of a climatic change that within a half century could turn the state into a desert.

On June 22 in Washington, where it hit 100 degrees, Rafe Pomerance received a call from Jim Hansen, who was scheduled to testify the following morning at a Senate hearing called by Timothy Wirth. “I hope we have good media coverage tomorrow,” Hansen said.

Hansen had just received the most recent global temperature data. Just over halfway into the year, 1988 was setting records. Already it had nearly clinched the hottest year in history. Ahead of schedule, the signal was emerging from the noise. “I’m going to make a pretty strong statement,” Hansen said.

Hansen returned to his testimony. He wrote: “The global warming is now large enough that we can ascribe with a high degree of confidence a cause-and-effect relationship to the greenhouse effect.” He wrote: “1988 so far is so much warmer than 1987, that barring a remarkable and improbable cooling, 1988 will be the warmest year on record.” He wrote: “The greenhouse effect has been detected, and it is changing our climate now.”

“We have only one planet,” Senator Bennett Johnston intoned. “If we screw it up, we have no place to go.” Senator Max Baucus, a Democrat from Montana, called for the United Nations Environment Program to begin preparing a global remedy to the carbon-dioxide problem. Senator Dale Bumpers, a Democrat of Arkansas, previewed Hansen’s testimony, saying that it “ought to be cause for headlines in every newspaper in America tomorrow morning.” The coverage, Bumpers emphasized, was a necessary precursor to policy. “Nobody wants to take on any of the industries that produce the things that we throw up into the atmosphere,” he said. “But what you have are all these competing interests pitted against our very survival.”

Hansen, wiping his brow, spoke without affect, his eyes rarely rising from his notes. The warming trend could be detected “with 99 percent confidence,” he said. “It is changing our climate now.” But he saved his strongest comment for after the hearing, when he was encircled in the hallway by reporters. “It is time to stop waffling so much,” he said, “and say that the evidence is pretty strong that the greenhouse effect is here.”

The press followed Bumpers’s advice. Hansen’s testimony prompted headlines in dozens of newspapers across the country, including The New York Times, which announced, across the top of its front page: “Global Warming Has Begun, Expert Tells Senate.”

Rafe Pomerance called his allies on Capitol Hill, the young staff members who advised politicians, organized hearings, wrote legislation. We need to finalize a number, he told them, a specific target, in order to move the issue — to turn all this publicity into policy. The Montreal Protocol had called for a 50 percent reduction in CFC emissions by 1998. What was the right target for carbon emissions? It wasn’t enough to exhort nations to do better. That kind of talk might sound noble, but it didn’t change investments or laws. They needed a hard goal — something ambitious but reasonable. And they needed it soon: Just four days after Hansen’s star turn, politicians from 46 nations and more than 300 scientists would convene in Toronto at the World Conference on the Changing Atmosphere, an event described by Philip Shabecoff of The New York Times as “Woodstock for climate change.”

Pomerance had a proposal: a 20 percent reduction in carbon emissions by 2000. Ambitious, Harwood said. In all his work planning climate policy, he had seen no assurance that such a steep drop in emissions was possible. Then again, 2000 was more than a decade off, so it allowed for some flexibility.

Mintzer pointed out that a 20 percent reduction was consistent with the academic literature on energy efficiency. Various studies over the years had shown that you could improve efficiency in most energy systems by roughly 20 percent if you adopted best practices.

Of course, with any target, you had to take into account the fact that the developing world would inevitably consume much larger quantities of fossil fuels by 2000. But those gains could be offset by a wider propagation of the renewable technologies already at hand — solar, wind, geothermal. It was not a rigorous scientific analysis, Mintzer granted, but 20 percent sounded plausible. We wouldn’t need to solve cold fusion or ask Congress to repeal the law of gravity. We could manage it with the knowledge and technology we already had.

Besides, Pomerance said, 20 by 2000 sounds good.

The conference’s final statement, signed by all 400 scientists and politicians in attendance, repeated the demand with a slight variation: a 20 percent reduction in carbon emissions by 2005. Just like that, Pomerance’s best guess became global diplomatic policy.

Hansen, emerging from Anniek’s successful cancer surgery, took it upon himself to start a one-man public information campaign. He gave news conferences and was quoted in seemingly every article about the issue; he even appeared on television with homemade props. Like an entrant at an elementary-school science fair, he made “loaded dice” out of sections of cardboard and colored paper to illustrate the increased likelihood of hotter weather in a warmer climate. Public awareness of the greenhouse effect reached a new high of 68 percent

global warming became a major subject of the presidential campaign. While Michael Dukakis proposed tax incentives to encourage domestic oil production and boasted that coal could satisfy the nation’s energy needs for the next three centuries, George Bush took advantage. “I am an environmentalist,” he declared on the shore of Lake Erie, the first stop on a five-state environmental tour that would take him to Boston Harbor, Dukakis’s home turf. “Those who think we are powerless to do anything about the greenhouse effect,” he said, “are forgetting about the White House effect.”

His running mate emphasized the ticket’s commitment to the issue at the vice-presidential debate. “The greenhouse effect is an important environmental issue,” Dan Quayle said. “We need to get on with it. And in a George Bush administration, you can bet that we will.”

This kind of talk roused the oil-and-gas men. “A lot of people on the Hill see the greenhouse effect as the issue of the 1990s,” a gas lobbyist told Oil & Gas Journal. Before a meeting of oil executives shortly after the “environmentalist” candidate won the election, Representative Dick Cheney, a Wyoming Republican, warned, “It’s going to be very difficult to fend off some kind of gasoline tax.” The coal industry, which had the most to lose from restrictions on carbon emissions, had moved beyond denial to resignation. A spokesman for the National Coal Association acknowledged that the greenhouse effect was no longer “an emerging issue. It is here already, and we’ll be hearing more and more about it.”

By the end of the year, 32 climate bills had been introduced in Congress, led by Wirth’s omnibus National Energy Policy Act of 1988. Co-sponsored by 13 Democrats and five Republicans, it established as a national goal an “International Global Agreement on the Atmosphere by 1992,” ordered the Energy Department to submit to Congress a plan to reduce energy use by at least 2 percent a year through 2005 and directed the Congressional Budget Office to calculate the feasibility of a carbon tax. A lawyer for the Senate energy committee told an industry journal that lawmakers were “frightened” by the issue and predicted that Congress would eventually pass significant legislation after Bush took office

The other great powers refused to wait. The German Parliament created a special commission on climate change, which concluded that action had to be taken immediately, “irrespective of any need for further research,” and that the Toronto goal was inadequate; it recommended a 30 percent reduction of carbon emissions

Margaret Thatcher, who had studied chemistry at Oxford, warned in a speech to the Royal Society that global warming could “greatly exceed the capacity of our natural habitat to cope” and that “the health of the economy and the health of our environment are totally dependent upon each other.”

The prime ministers of Canada and Norway called for a binding international treaty on the atmosphere; Sweden’s Parliament went further, announcing a national strategy to stabilize emissions at the 1988 level and eventually imposing a carbon tax

the United Nations unanimously endorsed the establishment, by the World Meteorological Organization and the United Nations Environment Program, of an Intergovernmental Panel on Climate Change, composed of scientists and policymakers, to conduct scientific assessments and develop global climate policy.

One of the I.P.C.C.’s first sessions to plan an international treaty was hosted by the State Department, 10 days after Bush’s inauguration. James Baker chose the occasion to make his first speech as secretary of state. “We can probably not afford to wait until all of the uncertainties about global climate change have been resolved,” he said. “Time will not make the problem go away.”

: On April 14, 1989, a bipartisan group of 24 senators, led by the majority leader, George Mitchell, requested that Bush cut emissions in the United States even before the I.P.C.C.’s working group made its recommendation. “We cannot afford the long lead times associated with a comprehensive global agreement,” the senators wrote. Bush had promised to combat the greenhouse effect with the White House effect. The self-proclaimed environmentalist was now seated in the Oval Office. It was time.

8. ‘You Never Beat The White House’ April 1989

After Jim Baker gave his boisterous address to the I.P.C.C. working group at the State Department, he received a visit from John Sununu, Bush’s chief of staff. Leave the science to the scientists, Sununu told Baker. Stay clear of this greenhouse-effect nonsense. You don’t know what you’re talking about. Baker, who had served as Reagan’s chief of staff, didn’t speak about the subject again.

despite his reputation as a political wolf, he still thought of himself as a scientist — an “old engineer,” as he was fond of putting it, having earned a Ph.D. in mechanical engineering from M.I.T. decades earlier. He lacked the reflexive deference that so many of his political generation reserved for the class of elite government scientists.

Since World War II, he believed, conspiratorial forces had used the imprimatur of scientific knowledge to advance an “anti-growth” doctrine. He reserved particular disdain for Paul Ehrlich’s “The Population Bomb,” which prophesied that hundreds of millions of people would starve to death if the world took no step to curb population growth; the Club of Rome, an organization of European scientists, heads of state and economists, which similarly warned that the world would run out of natural resources; and as recently as the mid-’70s, the hypothesis advanced by some of the nation’s most celebrated scientists — including Carl Sagan, Stephen Schneider and Ichtiaque Rasool — that a new ice age was dawning, thanks to the proliferation of man-made aerosols. All were theories of questionable scientific merit, portending vast, authoritarian remedies to halt economic progress.

When Mead talked about “far-reaching” decisions and “long-term consequences,” Sununu heard the marching of jackboots.

Sununu had suspected that the greenhouse effect belonged to this nefarious cabal since 1975, when the anthropologist Margaret Mead convened a symposium on the subject at the National Institute of Environmental Health Sciences.

While Sununu and Darman reviewed Hansen’s statements, the E.P.A. administrator, William K. Reilly, took a new proposal to the White House. The next meeting of the I.P.C.C.’s working group was scheduled for Geneva the following month, in May; it was the perfect occasion, Reilly argued, to take a stronger stand on climate change. Bush should demand a global treaty to reduce carbon emissions.

Sununu wouldn’t budge. He ordered the American delegates not to make any commitment in Geneva. Very soon after that, someone leaked the exchange to the press.

A deputy of Jim Baker pulled Reilly aside. He said he had a message from Baker, who had observed Reilly’s infighting with Sununu. “In the long run,” the deputy warned Reilly, “you never beat the White House.”

9. ‘A Form of Science Fraud’ May 1989

The cameras followed Hansen and Gore into the marbled hallway. Hansen insisted that he wanted to focus on the science. Gore focused on the politics. “I think they’re scared of the truth,” he said. “They’re scared that Hansen and the other scientists are right and that some dramatic policy changes are going to be needed, and they don’t want to face up to it.”

The censorship did more to publicize Hansen’s testimony and the dangers of global warming than anything he could have possibly said. At the White House briefing later that morning, Press Secretary Marlin Fitzwater admitted that Hansen’s statement had been changed. He blamed an official “five levels down from the top” and promised that there would be no retaliation. Hansen, he added, was “an outstanding and distinguished scientist” and was “doing a great job.”

10. The White House Effect Fall 1989

The Los Angeles Times called the censorship “an outrageous assault.” The Chicago Tribune said it was the beginning of “a cold war on global warming,” and The New York Times warned that the White House’s “heavy-handed intervention sends the signal that Washington wants to go slow on addressing the greenhouse problem.”

Darman went to see Sununu. He didn’t like being accused of censoring scientists. They needed to issue some kind of response. Sununu called Reilly to ask if he had any ideas. We could start, Reilly said, by recommitting to a global climate treaty. The United States was the only Western nation on record as opposing negotiations.

Sununu sent a telegram to Geneva endorsing a plan “to develop full international consensus on necessary steps to prepare for a formal treaty-negotiating process. The scope and importance of this issue are so great that it is essential for the U.S. to exercise leadership.”

Sununu seethed at any mention of the subject. He had taken it upon himself to study more deeply the greenhouse effect; he would have a rudimentary, one-dimensional general circulation model installed on his personal desktop computer. He decided that the models promoted by Jim Hansen were a lot of bunk. They were horribly imprecise in scale and underestimated the ocean’s ability to mitigate warming. Sununu complained about Hansen to D. Allan Bromley, a nuclear physicist from Yale who, at Sununu’s recommendation, was named Bush’s science adviser. Hansen’s findings were “technical poppycock” that didn’t begin to justify such wild-eyed pronouncements that “the greenhouse effect is here” or that the 1988 heat waves could be attributed to global warming, let alone serve as the basis for national economic policy.

When a junior staff member in the Energy Department, in a meeting at the White House with Sununu and Reilly, mentioned an initiative to reduce fossil-fuel use, Sununu interrupted her. “Why in the world would you need to reduce fossil-fuel use?” he asked. “Because of climate change,” the young woman replied. “I don’t want anyone in this administration without a scientific background using ‘climate change’ or ‘global warming’ ever again,” he said. “If you don’t have a technical basis for policy, don’t run around making decisions on the basis of newspaper headlines.” After the meeting, Reilly caught up to the staff member in the hallway. She was shaken. Don’t take it personally, Reilly told her. Sununu might have been looking at you, but that was directed at me.

Reilly, for his part, didn’t entirely blame Sununu for Bush’s indecision on the prospect of a climate treaty. The president had never taken a vigorous interest in global warming and was mainly briefed about it by nonscientists. Bush had brought up the subject on the campaign trail, in his speech about the White House effect, after leafing through a briefing booklet for a new issue that might generate some positive press. When Reilly tried in person to persuade him to take action, Bush deferred to Sununu and Baker. Why don’t the three of you work it out, he said. Let me know when you decide

Relations between Sununu and Reilly became openly adversarial. Reilly, Sununu thought, was a creature of the environmental lobby. He was trying to impress his friends at the E.P.A. without having a basic grasp of the science himself.

Pomerance had the sinking feeling that the momentum of the previous year was beginning to flag. The censoring of Hansen’s testimony and the inexplicably strident opposition from John Sununu were ominous signs. So were the findings of a report Pomerance had commissioned, published in September by the World Resources Institute, tracking global greenhouse-gas emissions. The United States was the largest contributor by far, producing nearly a quarter of the world’s carbon emissions, and its contribution was growing faster than that of every other country. Bush’s indecision, or perhaps inattention, had already managed to delay the negotiation of a global climate treaty until 1990 at the earliest, perhaps even 1991. By then, Pomerance worried, it would be too late.

Pomerance tried to be more diplomatic. “The president made a commitment to the American people to deal with global warming,” he told The Washington Post, “and he hasn’t followed it up.” He didn’t want to sound defeated. “There are some good building blocks here,” Pomerance said, and he meant it. The Montreal Protocol on CFCs wasn’t perfect at first, either — it had huge loopholes and weak restrictions. Once in place, however, the restrictions could be tightened. Perhaps the same could happen with climate change. Perhaps. Pomerance was not one for pessimism. As William Reilly told reporters, dutifully defending the official position forced upon him, it was the first time that the United States had formally endorsed the concept of an emissions limit. Pomerance wanted to believe that this was progress.
