So 1 kilogram of AMB-FUBINACA could be portioned out over 15,625 doses, with a typical street price of $35. That means the dealer stands to make close to $500,000.

As soon as the drug shows up on the radar of authorities, the makers move on to the next compound.

And if the dangers of synthetic cannabinoids have researchers concerned, the risks of designer opioids are perhaps even greater.

Just last month, the federal Drug Enforcement Administration issued an alert for a new designer drug called Pink, which had been responsible for 46 deaths, including 31 in New York and 10 in North Carolina.

“Pink belongs to a family of deadly synthetic opioids far more potent than morphine,” according to the agency. “It is usually imported to the United States, mainly from illicit labs in China.”

while it is not in the interest of dealers to kill their clients, as these synthetic compounds become increasingly potent, the risks will continue to grow.

“No compound that has been made yet has the potential to kill thousands of people,” he said. “But that is a scenario that is becoming more and more close to reality.”

it faces the same daunting task that confronted Carl Bosch a century ago: How much can it bring costs down? And how fast can it scale up

They believe that over the next seven years they can bring expenses down to a level that would enable them to sell CO₂ into more lucrative markets. Air-captured CO₂ can be combined with hydrogen and then fashioned into any kind of fossil-fuel substitute you want. Instead of making bread from air, you can make fuels from air.

What Gebald and Wurzbacher really want to do is to pull vast amounts of CO₂ out of the atmosphere and bury it, forever, deep underground, and sell that service as an offset

companies like Climeworks face a quandary: How do you sell something that never existed before, something that may never be cheap, into a market that is not yet real?

It’s arguably the case, in fact, that when it comes to reducing our carbon emissions, direct air capture will be seen as an option that’s too expensive and too modest in impact. “The only way that direct air capture becomes meaningful is if we do all the other things we need to do promptly,” Hal Harvey, a California energy analyst who studies climate-friendly technologies and policies, told me

In short, the best way to start making progress toward a decarbonized world is not to rev up millions of air capture machines right now. It’s to stop putting CO₂ in the atmosphere in the first place.

If the nations of the world were to continue on the current track, it would be impossible to meet the objectives of the 2016 Paris Agreement, which set a goal limiting warming to 2 degrees Celsius or, ideally, 1.5 degrees. And it would usher in a world of misery and economic hardship. Already, temperatures in some regions have climbed more than 1 degree Celsius, as a report by the Intergovernmental Panel on Climate Change noted last October. These temperature increases have led to an increase in droughts, heat waves, floods and biodiversity losses and make the chaos of 2 or 3 degrees’ additional warming seem inconceivable

A further problem is that maintaining today’s emissions path for too long runs the risk of doing irreparable damage to the earth’s ecosystems — causing harm that no amount of technological innovation can make right. “There is no reverse gear for natural systems,” Harvey says. “If they go, they go. If we defrost the tundra, it’s game over.” The same might be said for the Greenland and West Antarctic ice sheets, or our coral reefs. Such resources have an asymmetry in their natural architectures: They can take thousands or millions of years to form, but could reach conditions of catastrophic decline in just a few decades.

To have a shot at maintaining a climate suitable for humans, the world’s nations most likely have to reduce CO₂ emissions drastically from the current level — to perhaps 15 billion or 20 billion metric tons per year by 2030; then, through some kind of unprecedented political and industrial effort, we need to bring carbon emissions to zero by around 2050

To preserve a livable environment we may also need to extract CO₂ from the atmosphere. As Wurzbacher put it, “if you take all these numbers from the I.P.C.C., you end up with something like eight to 10 billion tons — gigatons — of CO₂ that need to be removed from the air every year, if we are serious about 1.5 or 2 degrees.

Through photosynthesis, our forests take extraordinary amounts of carbon dioxide from the atmosphere, and if we were to magnify efforts to reforest clear-cut areas — or plant new groves, a process known as afforestation — we could absorb billions more metric tons of carbon in future years.

we could grow crops specifically to absorb CO₂ and then burn them for power generation, with the intention of capturing the power-plant emissions and pumping them underground, a process known as bioenergy with carbon capture and storage, or BECCS

Ever since the Industrial Revolution, human societies have produced an excess of CO₂, by taking carbon stores from deep inside the earth — in the form of coal, oil and gas — and from stores aboveground (mostly wood), then putting it into the atmosphere by burning it. It has become imperative to reverse the process — that is, take CO₂ out of the air and either restore it deep inside the earth or contain it within new surface ecosystems.

“It’s not about saying, ‘I want to plant a tree.’ It’s about saying, ‘We want to plant a billion trees.’

“We have to come to grips with the fact that we waited too long and that we took some options off the table,” Michael Oppenheimer, a Princeton scientist who studies climate and policy, told me. As a result, NETs no longer seem to be just interesting ideas; they look like necessities. And as it happens, the Climeworks machines on the rooftop do the work each year of about 36,000 trees.

air capture could likewise help counter the impact of several vital industries. “There are process emissions that come from producing iron and steel, cement and glass,” she says, “and any time you make these materials, there’s a chemical reaction that emits CO₂.” Direct air capture could even lessen the impacts of the Haber-Bosch processes for making fertilizer; by some estimates, that industry now accounts for 3 percent of all CO₂ emissions.

Wind and solar are now the cheapest forms of energy in the right locations,” Pacala says. “The return on those investments, if you calculated it, would blow the doors off anything in your portfolio. It’s like investing in early Apple. So it’s a spectacular story of success. And direct air capture is precisely the same kind of problem, in which the only barrier is that it’s too costly.”

what all the founders have in common is a belief that the cost of capturing a ton of carbon will soon drop sharply.

M.I.T.’s Howard Herzog, for instance, an engineer who has spent years looking at the potential for these machines, told me that he thinks the costs will remain between $600 and $1,000 per metric ton

He points out that because direct-air-capture machines have to move tremendous amounts of air through a filter or solution to glean a ton of CO₂ — the gas, for all its global impact, makes up only about 0.04 percent of our atmosphere — the process necessitates large expenditures for energy and big equipment. What he has likewise observed, in analyzing similar industries that separate gases, suggests that translating spreadsheet projections for capturing CO₂ into real-world applications will reveal hidden costs. “I think there has been a lot of hype about this, and it’s not going to revolutionize anything,

Climeworks’s current goal is to remove 1 percent of the world’s annual CO₂ emissions by the mid 2020s.

“Basically, we have a road map — $600, down to $400, down to $300 and $200 a ton,” Wurzbacher said. “This is over the next five years. Down to $200 we know quite well what we’re doing.” And beyond $200, Wurzbacher suggested, things get murkier.

To actually capture 1 percent of the world’s carbon emissions by 2025 would, by Gebald’s calculations, require that Climeworks build 250,000 carbon-capture plants like the ones on the roof at Hinwil. That adds up to about 4.5 million carbon collectors

The Climeworks founders therefore try to think of their product as the automotive industry might — a piece of mass-produced technology and metal, not the carbon they hope to sequester.

“Every CO₂ collector has about the same weight and dimensions of a car — roughly two tons, and roughly 2 meters by 2 meters by 2 meters,” Gebald said. “And all the methods used to produce the CO₂ collectors could be well automated. So we have the automotive industry as a model for how to produce things in large quantities for low cost.

n 1954, the economist Paul Samuelson put forward a theory that made a distinction between “private-consumption goods” — bread, cars, houses and the like — and commodities that existed apart from the usual laws of supply and demand.

the other type of commodity Samuelson was describing is something now known as a “public good,” which benefits everyone but is not bought, sold or consumed the same way

direct air capture’s success would be limited to the size of the market for private goods — soda fizz, greenhouse gas — unless governments decided to intervene and help fund the equivalent of several million (or more) lighthouses.

An intervention could take a variety of forms. It could be large grants for research to find better sorbent materials, for instance, which would be similar to government investments that long ago helped nurture the solar- and wind-power industries. But help could also come by expanding regulations that already exist.

The Climeworks founders told me they don’t believe their company will succeed on what they call “climate impact” scales unless the world puts significant prices on emissions, in the form of a carbon tax or carbon fee.

“Our goal is to make it possible to capture CO₂ from the air for below $100 per ton,” Wurzbacher says. “No one owns a crystal ball, but we think — and we’re quite confident — that by something like 2030 we’ll have a global average price on carbon in the range of $100 to $150 a ton.” There is optimism in this thinking

A company that sells a product or uses a process that creates high emissions — an airline, for instance, or a steel maker — could be required to pay carbon-removal companies $100 per metric ton or more to offset their CO₂ output. Or a government might use carbon-tax proceeds to directly pay businesses to collect and bury CO₂.

“It doesn’t cost too much to pump CO₂ underground,” Stanford’s Sally Benson says. Companies already sequester about 34 million metric tons of CO₂ in the ground every year, at a number of sites around the world, usually to enhance the oil-drilling process. “The costs range from $2 to $15 per ton. So the bigger cost in all of this is the cost of carbon capture.”

The weekend before, Gutknecht told me, he received 900 unsolicited inquiries by email. Many were from potential customers who wanted to know how soon Climeworks could bury their CO₂ emissions, or how much a machine might cost them.

A Climeworks app could be installed on my smartphone, he explained. It could then be activated by my handset’s location services. “You fly over here to Europe,” he explained, “and the app tells you that you have just burned 1.7 tons of CO₂. Do you want to remove that? Well, Climeworks can remove it for you. Click here. We’ll charge your credit card.

The vast and constant market demand for fuel is why Carbon Engineering has staked its future on synthetics. The world currently burns about 100 million barrels of oil a day.

“So let’s say you’d have to supply something like 50 million barrels a day in 2050 of fuels,” he said. “That’s still a monster market.”

Carbon Engineering’s chief executive, added that direct-air-capture synthetics have an advantage over traditional fossil fuels: They won’t have to spend a dime on exploration

our plants, you can build it right in the middle of California, wherever you have air and water.” He told me that the company’s first large-scale facility should be up and running by 2022, and will turn out at least 500 barrels a day of fuel feedstock — the raw material sent to refineries.

Climeworks recently joined a consortium of European countries to produce synthetic methane that will be used by a local trucking fleet. With different tweaks and refinements, the process could be adapted for diesel, gasoline, jet fuel — or it could be piped directly to local neighborhoods as fuel for home furnaces.

the new fuels are not necessarily cheaper. Carbon Engineering aspires to deliver its product at an ultimate retail price of about $1 per liter, or $3.75 per gallon. What would make the product competitive are regulations in California that now require fuel sellers to produce fuels of lower “carbon intensity.” To date this has meant blending gas and diesel with biofuels like ethanol, but it could soon mean carbon-capture synthetics too.

Since they’re made from airborne CO₂ and hydrogen and could be manufactured just about anywhere, they could rearrange the geopolitical order — tempering the power of a handful of countries that now control natural-gas and oil markets.

From an environmental standpoint, air-capture fuels are not a utopian solution. Such fuels are carbon neutral, not carbon negative. They can’t take CO₂ from our industrial past and put it back into the earth

Even so, these fuels could present an enormous improvement. Transportation — currently the most significant source of emissions by sector in the United States — could cease to be a net emitter of CO₂

“If you can do one carbon-capture facility, where Carbon Engineering or Climeworks can build a big plant, great. You need to do that 5,000 times. And to capture a million tons of CO₂ with direct air capture, you need a small power plant just to run that facility. So if you’re going to build one direct-air-capture facility every day for the next 30 years to get to some of these scenarios, then in addition, we have to build a new mini power plant every day as well.

It’s also the case that you have to address two extraordinary problems at the same time, Peters added. “To reach 1.5 degrees, we need to halve emissions every decade,” he said. That would mean persuading entire nations, like China and the United States, to switch from burning coal to using renewables at precisely the same time that we make immense investments in negative-emission technologies.

this would need to be done even as governments choose among competing priorities:

“The idea of bringing direct air capture up to 10 billion tons by the middle or later part of the century is such a herculean task it would require an industrial scale-up the likes of which the world has never seen,”

Pacala wasn’t pessimistic about making a start. He seemed to think it was necessary for the federal government to begin with significant research and investments in the technology — to see how far and fast it could move forward, so that it’s ready as soon as possible

Gebald and Wurzbacher seemed to regard the climate challenge in mathematical terms. How many gigatons needed to be removed? How much would it cost per ton? How many Climeworks machines were required? Even if the figures were enormous, even if they appeared impossible, to see the future their way was to redefine the problem, to move away from the narrative of loss, to forget the multiplying stories of dying reefs and threatened coastlines — and to begin to imagine other possibilities.

Socially, the booming fast fashion industry is often built on low wages paid to women working in factories abroad but also increasingly in the UK

In the UK, we buy more clothes per person than any other country in Europe – five times what we bought in the 1980s, which creates 1.3m tonnes of waste each year, some 350,000 tonnes of which is dumped in landfill or incinerated.

Yet despite the overwhelming evidence gathered by the environmental audit committee (EAC), ministers this week rejected every recommendation for tackling abuses across the fashion industry, including a ban on incinerating or landfilling stock that can be recycled and a 1p charge on each garment to raise £35m a year for better clothing collection and sorting, a move supported by many in the industry.

But the response of the government was met with anger by many within the industry, where ethical fashion firms come up against others who produce at lower costs on the back of exploitative wage structures and environmentally damaging production models

“It is a vastly damaging industry that has been spiralling unchecked for far too long. The Earth and the people on it are exploited and damaged at every single step of the chain, and this culminates with unimaginable mountains of unused excess stock or badly made broken waste clothing with nowhere to go other than landfill or incineration.”

But others are less sure that voluntary measures will tackle what they say is a systemic power imbalance between brands and manufacturers, which leads to worker exploitation, or address the enormous environmental footprint of their trade.

“The fundamental problem with much of fast fashion is that its social and environmental costs are not taken into account. The environmental costs of materials and fabric are mostly offshored. The production that takes place in the UK often only pays half the legal minimum wage.

“So who is accountable for water and chemical pollution abroad, precarious work and employment, the undercutting of compliant manufacturers, the pollution from delivery and lack of recycling at home? Brands might find it difficult to make £5 fast fashion dresses and be socially and environmentally sustainable.

Ways to take the environmental heat out of your fashion habit

Commit to wearing every piece 30 times. If we doubled the amount of time we kept clothes for, we would cut our fashion emissions by 44%.

Get smart about fibres. Cheap cotton and synthetics come with huge environmental footprints. Cotton uses unsustainable amounts of water and pesticide. Go for hemp blended with organic cotton and silk and lyocel/modal.

Treat cotton as a luxury fibre. Buy products certified as organic to be free of the pesticide burden and plan to keep them for years.

Wash clothes less often. The average laundry cycle releases hundreds of thousands of tiny fragments of plastic from synthetic fibres into waterways. Put jeans in the freezer and remove dirt when frozen. Fleeces have been shown to release the most plastic fibres

Delete shopping apps from your phone and swear off insta-shopping for fashion. Go shopping for clothes in a shop.

f dry cleaning is a must, use an eco-friendly process: conventional dry cleaning harms the soil, air and wate

AIs like ChatGPT rapidly got better in their early days, but what we’ve seen in the past 14-and-a-half months are only incremental gains, says Marcus. “The truth is, the core capabilities of these systems have either reached a plateau, or at least have slowed down in their improvement,” he adds.

the gaps between the performance of various AI models are closing. All of the best proprietary AI models are converging on about the same scores on tests of their abilities, and even free, open-source models, like those from Meta and Mistral, are catching up.

models work by digesting huge volumes of text, and it’s undeniable that up to now, simply adding more has led to better capabilities. But a major barrier to continuing down this path is that companies have already trained their AIs on more or less the entire internet, and are running out of additional data to hoover up. There aren’t 10 more internets’ worth of human-generated content for today’s AIs to inhale.

A mature technology is one where everyone knows how to build it. Absent profound breakthroughs—which become exceedingly rare—no one has an edge in performance

companies look for efficiencies, and whoever is winning shifts from who is in the lead to who can cut costs to the bone. The last major technology this happened with was electric vehicles, and now it appears to be happening to AI.

the future for AI startups—like OpenAI and Anthropic—could be dim.

Microsoft and Google will be able to entice enough users to make their AI investments worthwhile, doing so will require spending vast amounts of money over a long period of time, leaving even the best-funded AI startups—with their comparatively paltry warchests—unable to compete.

Many other AI startups, even well-funded ones, are apparently in talks to sell themselves.

the bottom line is that for a popular service that relies on generative AI, the costs of running it far exceed the already eye-watering cost of training it.

That difference is alarming, but what really matters to the long-term health of the industry is how much it costs to run AIs. 

Changing people’s mindsets and habits will be among the biggest barriers to swift adoption of AI. That is a remarkably consistent pattern across the rollout of all new technologies.

the industry spent $50 billion on chips from Nvidia to train AI in 2023, but brought in only $3 billion in revenue.

For an almost entirely ad-supported company like Google, which is now offering AI-generated summaries across billions of search results, analysts believe delivering AI answers on those searches will eat into the company’s margins

Google, Microsoft and others said their revenue from cloud services went up, which they attributed in part to those services powering other company’s AIs. But sustaining that revenue depends on other companies and startups getting enough value out of AI to justify continuing to fork over billions of dollars to train and run those systems

three in four white-collar workers now use AI at work. Another survey, from corporate expense-management and tracking company Ramp, shows about a third of companies pay for at least one AI tool, up from 21% a year ago.

OpenAI doesn’t disclose its annual revenue, but the Financial Times reported in December that it was at least $2 billion, and that the company thought it could double that amount by 2025. 

That is still a far cry from the revenue needed to justify OpenAI’s now nearly $90 billion valuation

the company excels at generating interest and attention, but it’s unclear how many of those users will stick around. 

AI isn’t nearly the productivity booster it has been touted as

While these systems can help some people do their jobs, they can’t actually replace them. This means they are unlikely to help companies save on payroll. He compares it to the way that self-driving trucks have been slow to arrive, in part because it turns out that driving a truck is just one part of a truck driver’s job.

Add in the myriad challenges of using AI at work. For example, AIs still make up fake information,

getting the most out of open-ended chatbots isn’t intuitive, and workers will need significant training and time to adjust.

That’s because AI has to think anew every single time something is asked of it, and the resources that AI uses when it generates an answer are far larger than what it takes to, say, return a conventional search result

None of this is to say that today’s AI won’t, in the long run, transform all sorts of jobs and industries. The problem is that the current level of investment—in startups and by big companies—seems to be predicated on the idea that AI is going to get so much better, so fast, and be adopted so quickly that its impact on our lives and the economy is hard to comprehend. 

Mounting evidence suggests that won’t be the case.

It also was used by Nazi doctors in human malaria experiments in the Dachau concentration camp during World War II.German scientist Claus Schilling, an expert in tropical diseases, infected hundreds of patients with malaria by exposing them to parasite-carrying mosquitoes.He then treated them with quinine and other drugs to see how they reacted.“Thirty or forty died from the malaria itself,” Franz Blaha, a physician and Czech inmate at Dachau, testified after the war. “Three hundred to four hundred died later … because of the physical condition resulting from the malaria attacks. In addition there were deaths resulting from poisoning due to overdoses.”

At that time, malaria was mostly treated with the quinine-like synthetic Atabrine, a medicine designed by German chemists in the early 1930s.

Other bizarre remedies hadn’t worked, Duran-Reynals, the quinine historian, reported.One ancient cure went: “Take the urine of the patient and mix it with some flour to make … seventy-seven small cakes … Proceed before sunrise to an anthill and throw the cakes therein. As soon as the insects have devoured the cakes the fever vanishes.”

But Atabrine, like quinine, had side effects, including gastritis, hallucinations and psychosis, Masterson wrote. Plus, it turned the skin of GIs and Marines yellow.“The most hair-raising [side effects] were rashes that … progressed grotesquely, with skin falling off in sheets, creating open sores that attracted flies,” Masterson wrote. Other side effects included “erratic mood swings, violent anger, and deep depression …[along with] the standard diarrhea, vomiting, and cramps.”Then came the rumor the drug caused impotence.During the fight for the Pacific island of Guadalcanal, Marines rejected Atabrine. Their officers had to watch them take the pills and make sure the pills were swallowed. But the Marines would later spit them out.Thousands got sick. “For every battle casualty, ten men lay sick with malaria,” Masterson wrote.

“A tree grows which they call ‘the fever tree’ … whose bark, of the color of cinnamon, made into powder … and given as a beverage, cures the fevers … it has produced miraculous results,” he reported.“Thus … did Father Calancha announce to the world that a cure had been found for the most widespread disease of the time,” Duran-Reynals wrote.

In the 1670s, despite the hidebound medical establishment, a young English pharmacist, Robert Talbor, became an expert in treating fevers. He had moved to the southeast coast of England, where fevers were “epidemical."By trial and error, he came up with a secret formula — “my particular … medicine,” he called it. He would reveal only that it was “a preparation of four vegetables,” and he warned people about using the “Jesuits’ Powder.”

The whole virtue of the pills consisted in the quinine alone.

There’s little predictability in how things will play out after this anthropogenic jolt, especially in the living world. [More on the “great acceleration” behind the jolt is here.]

That’s a very different sensation than, say, mourning the end of nature. It’s more a celebration, in a way — a deeper acceptance of our place on the planet, with all of our synthetic trappings, and our faults, as fundamentally natural.

on whether it’s possible to have a “good Anthropocene.” Kolbert’s Twitter post last spring nicely captured their view:

Taking full ownership of the Anthropocene won’t be easy. The necessary feeling is a queasy mix of excitement and unease. I’ve compared it to waking up in the first car on the first run of a new roller coaster that hasn’t been examined fully by engineers.

Once you begin to get the many feedbacks bouncing off each other and bouncing off the Earth system, it’s going to be very hard to follow what’s going to happen, particularly biologically…. One could not imagine, at the very end of the Cretaceous, the beginning of the Tertiary, that the mammals — these itty-bitty little squeaky furry things, would take over – effectively taking the position that the dinosaurs held for so long. All we can say is that, for sure, it will be different. We’re going down a different trouser leg of history.

in the broadest sense we have to embrace the characteristics, good and bad, that make humans such a rare thing — a species that has become a planet-scale force.

“The way I would like to see it is in, say, 100 years in the future the London Geological Society will look back and consider this period…a transition from the lesser Anthropocene to the greater Anthropocene.”

Fully integrating this awareness into our personal choices and societal norms and policies will take time. It is “the great work,” as Thomas Berry put it.

Technology alone will not do the trick. Another keystone to better meshing humanity’s infinite aspirations with life on a finite planet will be slowly shifting value systems from the foundation up

Edward O. Wilson’s “Biophilia” was a powerful look outward at the characteristics of the natural world that we inherently cherish.

Now we need a dose of what I’ve taken to calling anthropophilia, as well.

We have to accept ourselves, flaws and all, in order to move beyond what has been something of an unconscious, species-scale pubescent growth spurt, enabled by fossil fuels in place of testosterone.

We’re stuck with “The World With Us.” It’s time to grasp that uncomfortable, but ultimately hopeful, idea.

Then, just as Lee was extolling his notion of “Asian values” abroad, something unexpected happened in China. Faced with social upheaval brought about by Deng Xiaoping’s economic reforms, leaders in Beijing began groping for new ways to maintain order themselves. Intrigued by what Lee had been doing in Singapore, they too began reviving aspects of their old cultural edifice as a stabilizing force. The cultural vacuums in Singapore and China may have had different origins, but some version of “Asian values” suddenly felt like a comfortable remedy for both.

“I consider Deng a greater leader who changed the destiny of China and the world,” he said. He was deeply gratified by the way that Deng had brought wealth, power, order and pride back to China—still his racial homeland—as well as to all Chinese.

Deng’s admiration of Lee was just as deep. He appreciated Lee’s pragmatism and friendship, especially his refusal to criticize China for its undemocratic form of statecraft, even after the infamy of 1989. And, because “the Singapore model” proved that a country could modernize without surrendering to “wholesale Westernization,” Deng (and all subsequent leaders in Beijing) celebrated it. “If I had only Shanghai, I too might be able to change Shanghai as quickly,” he once wistfully lamented of his success. “But I have the whole of China!”

For Lee, the Chinese aphorism that best captured the uniquely Asian/Confucian view of the individual’s role in society was: Xiushen, qijia, zhiguo, pingtianxia: “Bringing peace under heaven first requires cultivating oneself, then taking care of one’s family, and finally looking after one’s country.”

Various people have described today’s supremely well-ordered Singapore as “a think tank state,” “a paradise designed by McKinsey” or “Disneyland with the death penalty.”

Modern Singapore boasts the world’s second-busiest port, its most celebrated airline and an airport that hosts 15 million visitors a year. With an annual average growth rate of almost 7% since 1976, it now has a per capita income of well over $50,000, making it the wealthiest country in Asia. And it has the second most entrepreneurs per capita in the world, trailing only the U.S.

Where did his enormous commitment and energy come from? How was he able to create such an unusual success story from virtually nothing?

Lee was a very different leader from his confreres in Beijing, but he shared something important with them: a mutual sense that, despite the long, painful and humiliating history of the Chinese people’s modern weakness, it was their destiny to make something of themselves

Lee once described the Chinese as burdened by “a sense of frustration that they were down for so long” and as “enormously ambitious to catch up.” As this rebirth finally began in the 1990s, it allowed Lee to proudly proclaim that China’s “reawakened sense of destiny is an overpowering force.” In making such utterances, he seemed to be speaking as a Chinese who identified as much with his race as with his nation

When Lee’s ancestors joined the great Chinese diaspora, they were stripped of their culture and national identities. This defoliating process created, in them and later generations of overseas Chinese, a strange kind of hunger for advancement

in Singapore, Lee could begin to satisfy that longing for progress uninhibited by the conservative traditions that have so often clashed with modernizing impulses around the world. His new country may have been an almost synthetic nation, without a coherent cultural core, but this relative vacuum ended up being a blessing in disguise when it came to the challenges of creating a completely new state from the bottom up.

China faced a similar situation in the wake of its own tectonic revolutionary upheavals. Mao Zedong once spoke of his people as possessing “two remarkable peculiarities.” They were, he said, “first poor and secondly blank,” which meant that they were inclined to “want revolution.” As he observed, “a clean sheet of paper has no blotches, and so the newest and most beautiful pictures can be painted on it.”

Mao’s savage Cultural Revolution destroyed even more of his country’s cultural legacy. But he was fond of reminding his followers that, “Without destruction there can be no reconstruction.” By the time Deng came to power in the late 1970s, his own reforms met with little resistance from those traditional forces that had so obstructed change earlier in the century. Like Lee in Singapore, Deng was aided by the fact that traditional culture had already been demolished.

Lee Kuan Yew not only made Singaporeans proud; he also made Chinese and other Asians proud. He was a master builder, a sophisticated Asian nationalist dedicated not only to the success of his own small nation but to bequeathing the world a new model of governance

Instead of trying to impose Western political models on Asian realities, he sought to make autocracy respectable by leavening it with meritocracy, the rule of law and a strict intolerance for corruption to make it deliver growth.

He saw “Asian values” as a source of legitimacy for the idea that authoritarian leadership, constrained by certain Western legal and administrative checks, offered an effective “Asian” alternative to the messiness of liberal democracy. Because his thinking proved so agreeable to the Chinese Communist Party, he became the darling of Beijing. And because China has now become the political keystone of the modern Asian arch, Beijing’s imprimatur helped him and his ideas to gain a pan-Asian stature that Singapore alone could not have provided.

Dabiq is a town in northern Syria currently held by ISIS where, according to Islamic prophecy, the armies of Rome will mass to meet the armies of Islam.

And according to those prophecies, the Islamic armies will ultimately conquer Jerusalem and Rome.

No matter that the majority of Muslims -- even many jihadists - see ISIS' interpretations of the Quran and the hadith as manipulations or distortions.

The revival of the caliphate is the launching pad for a global battlefield. No caliph can govern without pursuing offensive jihad, and that jihad will continue, as Dabiq put it, until "the shade of the blessed flag will expand until it covers all eastern and western extents of the Earth."

"There will come a time when three armies of Islam shall simultaneously rise, one in the Levant, one in Yemen and one in Iraq."

It is powerful motivation to ISIS supporters, and it's also a message to Muslims: The end of times is at hand, and if you want to be a true Muslim, on the right side of history, you had better join us.

Abu Bakr al-Baghdadi said it was an obligation to establish the caliphate and therefore to recognize him as caliph.

A caliphate can only exist if it holds territory: ISIS' raison d'etre is to sustain and expand

ISIS followers -- and Dabiq -- are fond of quoting the words of Abu Musab al-Zarqawi -- the "spiritual" father of the movement and leader of al Qaeda in Iraq until he was killed in 2006.

Libya is the only other country where ISIS holds territory -- the coastal town of Sirte and other patches along the Mediterranean

Libyan territory can also be (and has been) the platform for launching terror attacks in neighboring Egypt and Tunisia.

But ISIS' ambitions run much further -- it has established a presence in Yemen, Afghanistan and the Sinai Peninsula in Egypt.

ISIS does not recognize the borders of nation states that make up the modern world nor the idea of a democratic state or citizenship.

"The Islamic State does not recognize synthetic borders, nor any citizenship besides Islam," he declared in 2012.

"We won't enjoy life until we liberate the Muslims everywhere, and until we retrieve Al-Quds (Jerusalem) and regain Al-Andalus (Andalucia in Spain), and conquer Rome," Adnani said in 2013.

ISIS wants to stir religious hatred in Europe and the United States -- so that Muslims no longer feel they belong in the West, and either carry out attacks in their homelands or leave to join the caliphate.

It has already shown extreme cruelty toward Shiites -- most notably slaughtering more than 1,500 Iraqi air force cadets in Tikrit in June 2014.

And it sees the United States as complicit in supporting a Shia government in Iraq.

Embroiling the U.S. and the West in a land war -- ISIS reasons -- would give Muslims no choice but to come to the defense of the caliphate, setting up a global confrontation.

"Now that it has taken Dabiq, the Islamic State awaits the arrival of an enemy army there, whose defeat will initiate the countdown to the apocalypse,"

"We will conquer your Rome, break your crosses, and enslave your women. If we do not reach that time, then our children and grandchildren will reach it."

The four were verified on 30 December by the US-based International Union of Pure and Applied Chemistry, the global organisation that governs chemical nomenclature, terminology and measurement.

IUPAC announced that a Russian-American team of scientists at the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California had produced sufficient evidence to claim the discovery of elements 115, 117 and 118.

The body awarded credit for the discovery of element 113, which had also been claimed by the Russians and Americans, to a team of scientists from the Riken institute in Japan.

Kosuke Morita, who was leading the research at Riken, said his team now planned to “look to the unchartered territory of element 119 and beyond.” Ryoji Noyori, former Riken president and Nobel laureate in chemistry said: “To scientists, this is of greater value than an Olympic gold medal”.

The elements, which currently bear placeholder names, will be officially named by the teams that discovered them in the coming months. Element 113 will be the first element to be named in Asia.

“IUPAC has now initiated the process of formalising names and symbols for these elements temporarily named as ununtrium, (Uut or element 113), ununpentium (Uup, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118).”

New elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist.

The four new elements, all of which are synthetic, were discovered by slamming lighter ­nuclei into each other and tracking the following decay of the radioactive superheavy elements.

Like other superheavy elements that populate the end of the periodic table, they only exist for fractions of a second before decaying into other elements.

The upshot is that “fake news”—the political logic, not the synthetic variety—has become more than a talking point for the American president and his imitators. It has had and will continue to have real-world consequences, both for American democracy and beyond America’s shores. As the British minister Matt Hancock recently testified to the House of Lords, “the basis of a free democracy is to have an agreed, objective basis of fact off which to have political disagreements.” Hancock felt compelled to make one more point: “Objective reality … exists.”

Arendt put it differently. “Conceptually, we may call truth what we cannot change,” she wrote in the essay “Truth and Politics.” But “metaphorically, it is the ground on which we stand and the sky that stretches above us.”

At no other time in human history has fashion been so accessible to so many people. Technology will help to make fashion greener. Better regulation of supply chains will help too. There is a discernible shift from discarding clothes to repairing, reusing or even renting them. However, it is hard to see how this will be enough to make fashion truly sustainable if the industry still produces more and more clothes. Once normal service is resumed, we need to think again about the wisdom of fostering competitive consumption, which upholds the persistent demand for expansion, in our society.

their explanation begins by dismantling several others.

Was the source of the problem America’s all-too-ready supply of prescription opioids?

About a million Americans now use heroin daily or near-daily. Many others use illicitly obtained synthetic opioids like fentanyl.

As Case and Deaton note, most people who abuse or become addicted to opioids continue to lead functional lives and many eventually escape their dependence

The oversupply of opioids did not create the conditions for despair. Instead, it appears, the oversupply fed upon a white working class already adrift.

although opioid deaths plateaued, at least temporarily, in 2018, suicides and alcohol-related deaths continue upward.

Could deaths of despair be related to the rising incidence of obesity?

Case and Deaton report that we’re seeing the same troubling health trends “among the underweight, normal weight, overweight, and obese.”

Is the problem poverty?

Overdose deaths are most common in high-poverty Appalachia and along the low-poverty Eastern Seaboard, in places such as Massachusetts, New Hampshire, Delaware, and Connecticut. Meanwhile, some high-poverty states, such as Arkansas and Mississippi, have been less affected. Black and Hispanic populations are poorer but less affected, too.

How about income inequality? Case and Deaton have found that patterns of inequality, like patterns of poverty, simply don’t match the patterns of mortality by race or region.

A consistently strong economic correlate, by contrast, is the percentage of a local population that is employed

In the late nineteen-sixties, Case and Deaton note, all but five per cent of men of prime working age, from twenty-five to fifty-four, had jobs; by 2010, twenty per cent did not.

What Case and Deaton have found is that the places with a smaller fraction of the working-age population in jobs are places with higher rates of deaths of despair—and that this holds true even when you look at rates of suicide, drug overdoses, and alcohol-related liver disease separately. They all go up where joblessness does.

Conservatives tend to offer cultural explanations

People are taking the lazy way out of responsibilities, the argument goes, and so they choose alcohol, drugs, and welfare and disability checks over a commitment to hard work, family, and community. And now they are paying the price for their hedonism and decadence—with addiction, emptiness, and suicide.

Yet, if the main problem were that a large group of people were withdrawing from the workforce by choice, wages should have risen in parallel.

Case and Deaton argue that the problem arises from the cumulative effect of a long economic stagnation and the way we as a nation have dealt with it

For the first few decades after the Second World War, per-capita U.S. economic growth averaged between two and three per cent a year. In the nineties, however, it dipped below two per cent. In the early two-thousands, it was less than one per cent. This past decade, it remained below 1.5 per cent.

Different populations have experienced this slowdown very differently

Anti-discrimination measures improved earnings and job prospects for black and Hispanic Americans. Though their earnings still lag behind those of the white working class, life for this generation of people of color is better than it was for the last.

Not so for whites without a college education. Among the men, median wages have not only flattened; they have declined since 1979. The work that the less educated can find isn’t as stable: hours are more uncertain, and job duration is shorter

Among advanced economies, this deterioration in pay and job stability is unique to the United States.

In the past four decades, Americans without bachelor’s degrees—the majority of the working-age population—have seen themselves become ever less valued in our economy. Their effort and experience provide smaller rewards than before, and they encounter longer periods between employment.

The problem isn’t that people are not the way they used to be. It’s that the economy and the structure of work are not the way they used to be

Today, about seventy-five per cent of college graduates are married by age forty-five, but only sixty per cent of non-college graduates are

Nonmarital childbearing has reached forty per cent among less educated white women.

Religious institutions previously played a vital role in connecting people to a community. But the number of Americans who attend religious services has declined markedly over the past half century, falling to just one-third of the general population today.

Case and Deaton see a picture of steady economic and social breakdown, amid over-all prosperity.

climate—the amount of social and economic instability not only in your life but also in your family and community—matters, too. Émile Durkheim pointed out more than a century ago that despair and then suicide result when people’s material and social circumstances fall below their expectations.

why has the steep rise in deaths of despair been so uniquely American

The United States has provided unusually casual access to means of death.

The availability of opioids has indeed played a role, and the same goes for firearms

The U.S. has also embraced automation and globalization with greater alacrity and fewer restrictions than other countries have. Displaced workers here get relatively little in the way of protection and support.

And we’ve enabled capital to take a larger share of the economic gains. “Economists long thought that the ratio of wages to profits was an immutable constant, about two to one,” Case and Deaton point out. But since 1970, they find, it has declined significantly.

A more unexpected culprit identified by Case and Deaton is our complicated and costly health-care system.

The focus of Case and Deaton’s indictment is on the fact that America’s health-care system is peculiarly reliant on employer-provided insurance.

As they show, the premiums that employers pay amount to a perverse tax on hiring lower-skilled workers.

According to the Kaiser Family Foundation, in 2019 the average family policy cost twenty-one thousand dollars, of which employers typically paid seventy per cent.

“For a well-paid employee earning a salary of $150,000, the average family policy adds less than 10 percent to the cost of employing the worker,” Case and Deaton write. “For a low-wage worker on half the median wage, it is 60 percent.”

between 1970 and 2016, the earnings that laborers received fell twenty-one per cent. But their total compensation, taken to include the cost of their benefits (in particular, health care), rose sixty-eight per cent. Increases in health-care costs have devoured take-home pay for those below the median income.

this makes American health care itself a prime cause of our rising death rates.

we must change the way we pay for health care. Instead of preserving a system that discourages employers from hiring, retaining, and developing workers without bachelor’s degrees, we need to make health-care payments proportional to wages—as with tax-based systems like Medicare.

So far, the American approach to the rise in white working-class mortality has been to pour resources into addiction-treatment centers and suicide-prevention programs. Yet the rates of suicide and addiction remain sky-high. It’s as if we’re using pressure dressings on a bullet wound to the chest instead of getting at the source of the bleeding.

Case and Deaton want us to recognize that the more widespread response is a sense of hopelessness and helplessness. And here culture does play a role.

When it comes to people whose lives aren’t going well, American culture is a harsh judge: if you can’t find enough work, if your wages are too low, if you can’t be counted on to support a family, if you don’t have a promising future, then there must be something wrong with you

We Americans are reluctant to acknowledge that our economy serves the educated classes and penalizes the rest. But that’s exactly the situation, and “Deaths of Despair” shows how the immiseration of the less educated has resulted in the loss of hundreds of thousands of lives, even as the economy has thrived and the stock market has soared.

capitalism, having failed America’s less educated workers for decades, must change, as it has in the past. “There have been previous periods when capitalism failed most people, as the Industrial Revolution got under way at the beginning of the nineteenth century, and again after the Great Depression,” they write. “But the beast was tamed, not slain.”

Today, the battles are over an employer-based system for financing health care, corporate governance that puts shareholders’ interests ahead of workers’, tax plans that benefit capital holders over wage earners.

We are better at addressing fast-moving crises than slow-building ones. It wouldn’t be surprising, then, if we simply absorbed current conditions as the new normal.

Market forces have worked hard to make sure we don’t notice the depredations we’re complicit in: the microplastics that pollute our waterways every time we wash a fleece jacket or a polyester blouse, the toilet tissue that’s destroying the boreal forest, the poisons we spray on our yards — up to 10 times as much, per acre, as farmers use — because they are marketed to us as benign “applications.”

Many people no longer feel a connection to the natural world because they no longer feel themselves to be a part of it. We’ve come to think of nature as something that exists a car ride away. We don’t even know the names of the trees in our own yards.

Nature is all around us anyway, and I’m not talking about just the songbirds and the cottontail rabbits in any suburban neighborhood. I’m talking about the coyote holed up in a bathroom at Nashville’s downtown convention center; the red-tailed hawks nesting in Manhattan; the raccoon climbing a skyscraper in St. Paul, Minn.; the black bear lounging in a Gatlinburg, Tenn., hot tub; the eastern box turtle knocking on my friend Mary Laura Philpott’s front door.

Recognizing that kinship will do more than keep our fellow creatures safer. It will also keep us safer, and make us happier, too.

So in recent years, scientists started creating structures that resemble human embryos in the lab by using chemical signals to coax cells into forming themselves into entities that look like very primitive human embryos.

Now, Wu's team and another international team of scientists have gone further than ever before. They created hollow balls of cells that closely resemble embryos at the stage when they usually implant in the womb, which are known as blastocysts. The new laboratory-made embryos have been dubbed "blastoids."

Now with this technique we can make hundreds of these structures. So this will allow us to scale up our understanding of very early human development. We think this will be very important." Some other scientists are hailing the research.

The goal of the experiments is to gain important insights into early human development and find new ways to prevent birth defects and miscarriages and treat fertility problems.But the research, which was published in two separate papers Wednesday in the journal Nature Portfolio, raises sensitive moral and ethical concerns.

The two experiments started with different cells to get similar results. Wu's group created his blastoids from human embryonic stem cells, and from "induced pluripotent stem cells," which are made from adult cells. Polo's group started with adult skin cells.

Hyun agrees the research is very important and could lead to a many other advances. But Hyun says it's important to come up with clear guidelines about how scientists can responsibly be permitted to pursue this kind of research.

Hyun favors revising a guideline known as the 14-day rule, which prohibits experiments on human embryos in the lab beyond two weeks of their existence. Hyun says exceptions should be allowed under certain carefully reviewed conditions.

But others worry about easing the 14-day rule.That could mean "we could just keep growing these sort-of humans in a test tube and not even considering the fact that they're so close to being human, right?"

In fact, another team of scientists at the Weizmann Institute of Science in Israel figured out how to grow mouse embryos outside the womb — a step toward creating an "artificial womb," according to report published Wednesday in the journal Nature.

An international group of researchers led by Monash University in Melbourne, published a paper in the journal Nature Materials earlier this year outlining the use of a technology that uses synthetic membranes to filter out the lithium from the brine.

Doctors and forensic scientists have long known that certain medical procedures turn people into chimeras, but where exactly a donor’s DNA shows up — beyond blood — has rarely been studied with criminal applications in mind.

The average doctor does not need to know where a donor’s DNA will present itself within a patient. That’s because this type of chimerism is not likely to be harmful. Nor should it change a person. “Their brain and their personality should remain the same,”

for a forensic scientist, it’s a different story. The assumption among criminal investigators as they gather DNA evidence from a crime scene is that each victim and each perpetrator leaves behind a single identifying code — not two

In 2004, investigators in Alaska uploaded a DNA profile extracted from semen to a criminal DNA database. It matched a potential suspect. But there was a problem: The man had been in prison at the time of the assault. It turned out that he had received a bone marrow transplant. The donor, his brother, was eventually convicted.

she heard about another disconcerting scenario since then. It involved police investigators who were skeptical of a sexual assault victim’s account because she said there had been one attacker, though DNA analysis showed two. Eventually the police determined that the second profile had come from her bone marrow donor.

In 2008, he was trying to identify the victim of a traffic accident for the National Forensic Service in Seoul, South Korea. Blood showed that the individual was female. But the body appeared to be male, which was confirmed by DNA in a kidney, but not in the spleen or the lung, which contained male and female DNA. Eventually, he figured out that the victim had received a bone marrow transplant from his daughter.

Fraternal twins sometimes acquire each other’s DNA in the womb; in at least one case that led to unfounded fears of infidelity when a man’s child did not seem to be his. In another case, a mother nearly lost custody of her children after a DNA test.

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
