While testing has been comparatively limited, the continent appears to have bucked the doomsday predictions of global health experts. The telltale signs of severe outbreaks seen elsewhere — crowded hospitals and a spike in deaths — have emerged in only a handful of African countries. Surveys done by the World Health Organization have found negligible excess mortality rates in most African countries, reducing suspicion that many covid-19 deaths are going uncounted.

even as more research emerges, public health experts caution that the explanation for why Africa’s caseload has remained low will be complicated.

“It is highly unlikely that there is a single, definitive answer as to why this is the case,” said Ngoy Nsenga, a Congolese epidemiologist and the WHO’s program manager for emergency response in Africa. “Youthful populations, warmer climates, less time indoors, less traveling, less obesity and diabetes, immunities derived from other diseases — even other coronaviruses — are all playing a part, we think. But what distinguishes Africa from other places like Brazil that might share those factors, but were still hard-hit, are our human interventions.”

Those interventions have exacted immense economic damage, however, and with many African governments not seeing uncontrolled growth in cases, they have been rolled back in many places.

Health officials, however, caution that the threat is far from over — even if hospitals aren’t filling up.

“During the holiday season, there will be a tendency for large movement from capital cities to villages, remote areas, for people to connect with families. That might drive the pandemic,”

Ndongo Dia, head of the respiratory virus diagnostic laboratory at the Pasteur Institute in Senegal’s capital, Dakar, isn’t sure why Senegal dodged the worst of the pandemic.

The nation has garnered widespread praise for its quick response, which included sealing its border, rolling out four-hour tests while Americans waited days for results, and imposing a curfew until infections slowed.

Beyond that, Dia said, “our luck is the composition of our population. The number of severe cases is going to be much lower compared to the northern countries, where there are more elderly people.”

Death rates have been higher in South Africa, Algeria, Egypt and Tunisia, where a larger percentage of the population is over the age of 65. Those four countries make up two-thirds of all coronavirus deaths in Africa.

Preliminary analyses done by the WHO indicate that Africans may be twice as likely to experience covid-19 without any illness, and that more than 80 percent of cases on the continent have been asymptomatic — a far higher percentage than elsewhere in the world.

“It is not different strains — that I can refute. We have a network of laboratories all over the continent and the world,” he said. “We have sequenced from many places, we haven’t seen dramatically different strains here.”

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Traditionally, a scientist submits her paper to a journal, which sends it to a (surprisingly small) group of peers for (several rounds of usually anonymous) comments; if the paper passes this (typically months-long) peer-review gantlet, it is published (often behind an expensive paywall). Languid and opaque, this system is ill-suited to a fast-moving outbreak. But biomedical scientists can now upload preliminary versions of their papers, or “preprints,” to freely accessible websites, allowing others to immediately dissect and build upon their results. This practice had been slowly gaining popularity before 2020, but proved so vital for sharing information about COVID‑19 that it will likely become a mainstay of modern biomedical research. Preprints accelerate science, and the pandemic accelerated the use of preprints. At the start of the year, one repository, medRxiv (pronounced “med archive”), held about 1,000 preprints. By the end of October, it had more than 12,000.

The U.S. is now catching up. In April, the NIH launched a partnership called ACTIV, in which academic and industry scientists prioritized the most promising drugs and coordinated trial plans across the country. Since August, several such trials have started.

Researchers have begun to uncover how SARS‑CoV‑2 compares with other coronaviruses in wild bats, the likely reservoir; how it infiltrates and co-opts our cells; how the immune system overreacts to it, creating the symptoms of COVID‑19. “We’re learning about this virus faster than we’ve ever learned about any virus in history,” Sabeti said.

Similar triumphs occurred last year—in other countries. In March, taking advantage of the United Kingdom’s nationalized health system, British researchers launched a nationwide study called Recovery, which has since enrolled more than 17,600 COVID‑19 patients across 176 institutions. Recovery offered conclusive answers about dexamethasone and hydroxychloroquine and is set to weigh in on several other treatments. No other study has done more to shape the treatment of COVID‑19.

SARS‑CoV‑2’s genome was decoded and shared by Chinese scientists just 10 days after the first cases were reported. By November, more than 197,000 SARS‑CoV‑2 genomes had been sequenced. About 90 years ago, no one had even seen an individual virus; today, scientists have reconstructed the shape of SARS‑CoV‑2 down to the position of individual atoms

Respiratory viruses, though extremely common, are often neglected. Respiratory syncytial virus, parainfluenza viruses, rhinoviruses, adenoviruses, bocaviruses, a quartet of other human coronaviruses—they mostly cause mild coldlike illnesses, but those can be severe. How often? Why? It’s hard to say, because, influenza aside, such viruses attract little funding or interest.

COVID‑19 has developed a terrifying mystique because it seems to behave in unusual ways. It causes mild symptoms in some but critical illness in others. It is a respiratory virus and yet seems to attack the heart, brain, kidneys, and other organs. It has reinfected a small number of people who had recently recovered. But many other viruses share similar abilities; they just don’t infect millions of people in a matter of months or grab the attention of the entire scientific community

Thanks to COVID‑19, more researchers are looking for these rarer sides of viral infections, and spotting them.

These factors pull researchers toward speed, short-termism, and hype at the expense of rigor—and the pandemic intensified that pull. With an anxious world crying out for information, any new paper could immediately draw international press coverage—and hundreds of citations.

“There’s a perception that they’re just colds and there’s nothing much to learn,” says Emily Martin of the University of Michigan, who has long struggled to get funding to study them. Such reasoning is shortsighted folly. Respiratory viruses are the pathogens most likely to cause pandemics, and those outbreaks could potentially be far worse than COVID‑19’s.

Their movements through the air have been poorly studied, too. “There’s this very entrenched idea,” says Linsey Marr at Virginia Tech, that viruses mostly spread through droplets (short-range globs of snot and spit) rather than aerosols (smaller, dustlike flecks that travel farther). That idea dates back to the 1930s, when scientists were upending outdated notions that disease was caused by “bad air,” or miasma. But the evidence that SARS‑CoV‑2 can spread through aerosols “is now overwhelming,”

Another pandemic is inevitable, but it will find a very different community of scientists than COVID‑19 did. They will immediately work to determine whether the pathogen—most likely another respiratory virus—moves through aerosols, and whether it spreads from infected people before causing symptoms. They might call for masks and better ventilation from the earliest moments, not after months of debate

They will anticipate the possibility of an imminent wave of long-haul symptoms, and hopefully discover ways of preventing them. They might set up research groups to prioritize the most promising drugs and coordinate large clinical trials. They might take vaccine platforms that worked best against COVID‑19, slot in the genetic material of the new pathogen, and have a vaccine ready within months

the single-minded focus on COVID‑19 will also leave a slew of negative legacies. Science is mostly a zero-sum game, and when one topic monopolizes attention and money, others lose out.

Long-term studies that monitored bird migrations or the changing climate will forever have holes in their data because field research had to be canceled.

negligence has left COVID‑19 long-haulers with few answers or options, and they initially endured the same dismissal as the larger ME community. But their sheer numbers have forced a degree of recognition. They started researching, cataloging their own symptoms. They gained audiences with the NIH and the World Health Organization. Patients who are themselves experts in infectious disease or public health published their stories in top journals. “Long COVID” is being taken seriously, and Brea hopes it might drag all post-infection illnesses into the spotlight. ME never experienced a pivot. COVID‑19 might inadvertently create one

Other epistemic trespassers spent their time reinventing the wheel. One new study, published in NEJM, used lasers to show that when people speak, they release aerosols. But as the authors themselves note, the same result—sans lasers—was published in 1946, Marr says. I asked her whether any papers from the 2020 batch had taught her something new. After an uncomfortably long pause, she mentioned just one.

The incentives to trespass are substantial. Academia is a pyramid scheme: Each biomedical professor trains an average of six doctoral students across her career, but only 16 percent of the students get tenure-track positions. Competition is ferocious, and success hinges on getting published

Conservationists who worked to protect monkeys and apes kept their distance for fear of passing COVID‑19 to already endangered species.

Among scientists, as in other fields, women do more child care, domestic work, and teaching than men, and are more often asked for emotional support by their students. These burdens increased as the pandemic took hold, leaving women scientists “less able to commit their time to learning about a new area of study, and less able to start a whole new research project,

published COVID‑19 papers had 19 percent fewer women as first authors compared with papers from the same journals in the previous year. Men led more than 80 percent of national COVID‑19 task forces in 87 countries. Male scientists were quoted four times as frequently as female scientists in American news stories about the pandemic.

American scientists of color also found it harder to pivot than their white peers, because of unique challenges that sapped their time and energy.

Science suffers from the so-called Matthew effect, whereby small successes snowball into ever greater advantages, irrespective of merit. Similarly, early hindrances linger. Young researchers who could not pivot because they were too busy caring or grieving for others might suffer lasting consequences from an unproductive year. COVID‑19 “has really put the clock back in terms of closing the gap for women and underrepresented minorities,”

In 1848, the Prussian government sent a young physician named Rudolf Virchow to investigate a typhus epidemic in Upper Silesia. Virchow didn’t know what caused the devastating disease, but he realized its spread was possible because of malnutrition, hazardous working conditions, crowded housing, poor sanitation, and the inattention of civil servants and aristocrats—problems that require social and political reforms. “Medicine is a social science,” Virchow said, “and politics is nothing but medicine in larger scale.”

entists discovered the microbes responsible for tuberculosis, plague, cholera, dysentery, and syphilis, most fixated on these newly identified nemeses. Societal factors were seen as overly political distractions for researchers who sought to “be as ‘objective’ as possible,” says Elaine Hernandez, a medical sociologist at Indiana University. In the U.S., medicine fractured.

New departments of sociology and cultural anthropology kept their eye on the societal side of health, while the nation’s first schools of public health focused instead on fights between germs and individuals. This rift widened as improvements in hygiene, living standards, nutrition, and sanitation lengthened life spans: The more social conditions improved, the more readily they could be ignored.

The ideological pivot away from social medicine began to reverse in the second half of the 20th century.

Politicians initially described COVID‑19 as a “great equalizer,” but when states began releasing demographic data, it was immediately clear that the disease was disproportionately infecting and killing people of color.

These disparities aren’t biological. They stem from decades of discrimination and segregation that left minority communities in poorer neighborhoods with low-paying jobs, more health problems, and less access to health care—the same kind of problems that Virchow identified more than 170 years ago.

In March, when the U.S. started shutting down, one of the biggest questions on the mind of Whitney Robinson of UNC at Chapel Hill was: Are our kids going to be out of school for two years? While biomedical scientists tend to focus on sickness and recovery, social epidemiologists like her “think about critical periods that can affect the trajectory of your life,” she told me. Disrupting a child’s schooling at the wrong time can affect their entire career, so scientists should have prioritized research to figure out whether and how schools could reopen safely. But most studies on the spread of COVID‑19 in schools were neither large in scope nor well-designed enough to be conclusive. No federal agency funded a large, nationwide study, even though the federal government had months to do so. The NIH received billions for COVID‑19 research, but the National Institute of Child Health and Human Development—one of its 27 constituent institutes and centers—got nothing.

The horrors that Rudolf Virchow saw in Upper Silesia radicalized him, pushing the future “father of modern pathology” to advocate for social reforms. The current pandemic has affected scientists in the same way

COVID‑19 could be the catalyst that fully reunifies the social and biological sides of medicine, bridging disciplines that have been separated for too long.

“To study COVID‑19 is not only to study the disease itself as a biological entity,” says Alondra Nelson, the president of the Social Science Research Council. “What looks like a single problem is actually all things, all at once. So what we’re actually studying is literally everything in society, at every scale, from supply chains to individual relationships.”

years of painstakingly worded treaties, high-level visits and cutting-edge disease surveillance—all meant to encourage good-faith cooperation—have only bitten around the edges of the problem.

“It can’t demand entry into a country because they think something bad is happening.”

Nearly 200 countries were counting on an agency whose budget—roughly $2.4 billion in 2020—is less than a sixth of the Maryland Department of Health’s. Its donors, largely Western governments, earmark most of that money for causes other than pandemic preparedness.

In 2018 and 2019, about 8% of the WHO’s budget went to activities related to pandemic preparedness

It took those experts more than four months to agree that widespread mask-wearing helps, and that people who are talking, shouting or singing can expel the virus through tiny particles that linger in the air. In that time, about half a million people died.

To write its recommendations, the WHO solicits outside experts, which can be a slow process.

the agency’s bureaucratic structure, diplomatic protocol and funding were no match for a pandemic as widespread and fast-moving as Covid-19.

As months rolled on, it became clear that governments were reluctant to allow the U.N. to scold, shame or investigate them.

In particular, The Wall Street Journal found:

* China appears to have violated international law requiring governments to swiftly inform the WHO and keep it in the loop about an alarming infectious-disease cluster

—there are no clear consequences for violations

* The WHO lost a critical week waiting for an advisory panel to recommend a global public-health emergency, because some of its members were overly hopeful that the new disease wasn’t easily transmissible from one person to another.

* The institution overestimated how prepared some wealthy countries were, while focusing on developing countries, where much of its ordinary assistance is directed

Public-health leaders say the WHO plays a critical role in global health, leading responses to epidemics and setting health policies and standards for the world. It coordinates a multinational effort every year to pick the exact strains that go into the seasonal flu vaccine, and has provided public guidance and advice on Covid-19 when many governments were silent.

The world’s public-health agency was born weak, created in 1948 over U.S. and U.K. reluctance. For decades, it was legally barred from responding to diseases that it learned about from the news. Countries were required to report outbreaks of only four diseases to the WHO: yellow fever, plague, cholera and smallpox, which was eradicated in 1980.

SARS convinced governments to retool the WHO. The next year, delegates arrived in the Geneva palace where the League of Nations once met to resolve a centuries-old paradox: Countries don’t report outbreaks, because they fear—correctly—their neighbors will respond by blocking travel and trade.

Nearly three times that amount was budgeted for eradicating polio, a top priority for the WHO’s two largest contributors: the U.S. and the Bill & Melinda Gates Foundation.

“Everybody pushed back. No sovereign country wants to have this.”

China wanted an exemption from immediately reporting SARS outbreaks. The U.S. argued it couldn’t compel its 50 states to cooperate with the treaty. Iran blocked American proposals to make the WHO focus on bioterrorism. Cuba had an hourslong list of objections.

Around 3:15 a.m. on the last day, exhausted delegates ran out of time. The treaty they approved, called the International Health Regulations, imagined that each country would quickly and honestly report, then contain, any alarming outbreaks

In return, the treaty discouraged restrictions on travel and trade. There would be no consequences for reporting an outbreak—yet no way to punish a country for hiding one.

The treaty’s key chokepoint: Before declaring a “public health emergency of international concern,” or PHEIC, the WHO’s director-general would consult a multinational emergency committee and give the country in question a chance to argue against such a declaration.

Delegates agreed this could give some future virus a head start but decided it was more important to discourage the WHO from making any unilateral announcements that could hurt their economies.

Over the next few years, emergency committees struggled over how to determine whether an outbreak was a PHEIC. It took months to declare emergencies for two deadly Ebola epidemics

On Jan. 3, representatives of China’s National Health Commission arrived at the WHO office in Beijing. The NHC acknowledged a cluster of pneumonia cases, but didn’t confirm that the new pathogen was a coronavirus, a fact Chinese officials already knew.

That same day, the NHC issued an internal notice ordering laboratories to hand over or destroy testing samples and forbade anyone from publishing unauthorized research on the virus.

China’s failure to notify the WHO of the cluster of illnesses is a violation of the International Health Regulations

China also flouted the IHR by not disclosing all key information it had to the WHO

The WHO said it’s up to member states to decide whether a country has complied with international health law, and that the coming review will address those issues.

While Chinese scientists had sequenced the genome and posted it publicly, the government was less forthcoming about how patients might be catching the virus.

WHO scientists pored over data they did get, and consulted with experts from national health agencies, including the CDC, which has 33 staff detailed to the WHO.

Then a 61-year-old woman was hospitalized in Thailand on Jan. 13.

The next day, Dr. van Kerkhove told reporters: “It’s certainly possible that there is limited human-to-human transmission.” MERS and SARS, both coronaviruses, were transmissible among people in close quarters. Epidemiological investigations were under way, she said.

On Jan. 22, a committee of 15 scientists haggled for hours over Chinese data and a handful of cases in other countries. Clearly, the virus was spreading between people in China, though there was no evidence of that in other countries. The question now: Was it mainly spreading from very sick people in hospitals and homes—or more widely?

The committee met over two days, but was split. They mostly agreed on one point: The information from China “was a little too imprecise to very clearly state that it was time” to recommend an emergency declaration,

On Jan. 28, Dr. Tedros and the WHO team arrived for their meeting with Mr. Xi

Leaning across three wooden coffee tables, Dr. Tedros pressed for cooperation. In the absence of information, countries might react out of fear and restrict travel to China, he repeated several times throughout the trip. Mr. Xi agreed to allow a WHO-led international team of experts to visit. It took until mid-February to make arrangements and get the team there.

China also agreed to provide more data, and Dr. Tedros departed, leaving Dr. Briand behind with a list of mysteries to solve. How contagious was the virus? How much were children or pregnant women at risk? How were cases linked? This was vital information needed to assess the global risk, Dr. Briand said

Back in Geneva, Dr. Tedros reconvened the emergency committee. By now it was clear there was human-to-human transmission in other countries. When it met on Jan. 30, the committee got the information the WHO had been seeking. This time the committee recommended and Dr. Tedros declared a global public-health emergency.

President Trump and New York Gov. Andrew Cuomo both assured constituents their health systems would perform well. The U.K.’s chief medical officer described the WHO’s advice as largely directed at poor and middle-income countries. As for keeping borders open, by then many governments had already closed them to visitors from China.

The WHO shifted focus to the developing world, where it believed Covid-19 would exact the heaviest toll. To its surprise, cases shot up just across the border, in northern Italy.

the WHO’s health emergencies unit should report to the director-general and not member states, and its budget should be protected so it doesn’t have to compete with other programs for money.

If there were one thing the WHO might have done differently, it would be to offer wealthier countries the type of assistance with public-health interventions that the WHO provides the developing world

the WHO’s warning system of declaring a global public-health emergency needs to change. Some want to see a warning system more like a traffic light—with color-coded alarms for outbreaks, based on how worried the public should be

Emergency committees need clearer criteria for declaring a global public-health emergency and should publicly explain their thinking

The WHO should have more powers to intervene in countries to head off a health crisis

Lessons learned

Implementing many of those ideas would require herding diplomats back for another monthslong slog of treaty revisions. If and when such talks begin, new governments will likely be in place, and political priorities will float elsewher

“Unfortunately, I’m very cynical about this,” he said. “We are living through cycles of panic and neglect. We’ve been through all of this before.”

He sounded a similar alarm in his final lecture at Yale, in 2013. Liberal education, he said, was failing to provide students with a common set of values and the tools to make sense of the world.

“I find a kind of cultural void and ignorance of the past, a sense of rootlessness and aimlessness, as though not only the students but the whole world was born yesterday,”

Attempting to ease tensions with China to make cooperation on global public health possible won’t work, partly because Beijing cannot credibly commit to being more transparent and cooperative in the future.

Xi did not want to facilitate an international response to COVID-19 that could have attributed blame to China or isolated it through travel restrictions, either of which might have damaged the regime’s domestic legitimacy. Instead, Xi leveraged the pandemic to his advantage: China’s suppression of the virus became a matter of national pride, held up by Beijing in sharp contrast to the experience of the United States.

But in case cooperation fails, it must have a backup plan to rally allies and partners to provide a much greater share of global public goods, even if that means shouldering more of the costs.

as a number of U.S. embassy officials told the foreign policy analyst Colin Kahl and me for our book Aftershocks, this team’s cooperation with the Chinese government became more challenging as U.S.-Chinese rivalry intensified, largely because of China’s actions.

When COVID-19 hit, the Chinese Communist Party (CCP) maintained near-absolute secrecy. All channels of communication between Beijing and Washington went silent, as they did between Beijing and other governments. Chinese leaders sought to conceal vital information about the emerging epidemic in China from the rest of the world, even attempting to prevent Chinese scientists from sharing the genetic sequence of the virus with scientists in other countries.

It is impossible to say for certain why the Chinese government behaved the way it did, but secrecy and control make sense in light of what the vast majority of China experts believe to be Xi’s top priority: regime survival.

For China’s leaders, the pandemic revealed the inexorable decline of the West, confirmed Beijing’s power and capabilities, and created more latitude for the CCP to do as it wished.

according to the UN, the pandemic could force a total of 490 million people into poverty—defined as the loss of access to clean water, adequate food, or shelter—pushing the global poverty rate to around seven percent by 2030, compared with the pre-pandemic target of three percent. 

Contrary to popular belief, some senior Trump administration officials grasped the national security threat posed by the virus faster than their European counterparts did. Top officials in the National Security Council began focusing on the pandemic in early January, just days after news of the outbreak in Wuhan, China, became public.

ven though Pottinger and other NSC officials were wise to the danger, they ultimately failed to persuade Trump to make the necessary preparations to deal with the pandemic when it inevitably reached the United States. 

As the administration began to formulate its response, those who favored a more comprehensive public health approach both at home and abroad were excluded or marginalized at crucial moments. The result was that the Trump administration focused more on holding China responsible for the outbreak and reducing U.S. reliance on Beijing than on the minutiae of global public health policy or the hard work of rallying the world to tackle the pandemic.

the pandemic and China’s response to it helped unify the administration behind a more comprehensive strategy to push back against Beijing. Between March 2020 and the end of the year, the senior official said, the United States put in place more containment measures than it had in the previous three years, including restrictions on Chinese technology firms, sanctions on Chinese officials, looser regulations on diplomatic contacts with Taiwan, and recognition of the repression in Xinjiang as a genocide. In this sense, the pandemic was a pivotal moment in the U.S.-Chinese rivalry. 

Competition between the two countries overwhelmed everything else, including U.S. cooperation with allies on the pandemic, leaving a global leadership vacuum that no one could fill.

The EU tried to step up by increasing funding for the WHO and for COVAX, the global initiative to share vaccines, but it never came close to organizing a global response. China’s assertive foreign policy, and its attempts to use pandemic assistance to advance its interests, aggravated European leaders and convinced them to harden their positions toward China throughout the course of 2020. 

During this period, there was hardly any international cooperation on vaccine development or distribution, no coordination on travel restrictions or the distribution of medical supplies, and limited cooperation on achieving a cessation of hostilities in conflict zones

The economic disruption caused by COVID-19 devastated low-income countries, which received little in the way of international assistance. Especially hard hit were countries, such as Bangladesh, that had made significant development gains in the last two decades and were propelling themselves into the lower tier of middle-income economies.

The United States needs a strategy to address transnational threats under the conditions of great-power competition. It must aim to cooperate with rivals, especially China, to prepare for future pandemics and to tackle climate change

Pandemics are not the only transnational threat that promises to intensify great-power rivalry and diminish the prospects for much-needed cooperation. Climate change could do the same.

Rather than unite the world around a common purpose, climate change is likely to deepen competition between major powers, especially as the transition away from fossil fuels creates economic winners and losers.

Countries that aggressively decarbonize could place sanctions and other trade restrictions on countries that do not, leading to counterresponses and new trade wars.

the impediments to cooperation between Europe and China on climate change “are becoming higher” and warn that “decision-makers must not underestimate the highly competitive aspects of how China is changing its energy production and consumption.” 

The United States and Europe will both compete with China for access to raw materials and in developing the technology needed to make their economies carbon neutral: magnets, batteries, high-performance ceramics, and light-emitting diodes, among other things

even if the U.S. government remains broadly aligned with Europe on climate policy, the Europeans could still become disaffected if Congress blocks meaningful climate action, such as commitments to cut carbon emissions or invest in clean technology. This, in turn, could diminish Europe’s willingness to help uphold the U.S.-led international order.

If, on the one hand, they mean softening U.S. rhetoric without conceding much of substance to China, they would do well to look to Europe, where governments were much more inclined than the Trump administration to cooperate with China, but China did not take them up on the offer.

If, on the other hand, they mean unilaterally making major geopolitical concessions to China—on its territorial acquisitions in the South China Sea, for instance, or the status of Taiwan—the United States would not only pay an extremely high price but also likely embolden Beijing further without actually securing cooperation on pandemics or climate change beyond what Beijing has already offered.

There is no getting around strategic competition with Beijing: it is deeply embedded in the international order, mainly because China seeks to expand its sphere of influence in Asia at the expense of the United States and its allies, which are in turn committed to thwarting Beijing’s plans.

The United States and China are also engaged in what Jake Sullivan, Biden’s national security adviser, recently called “a competition of models.” China is seeking to make the world safe for the CCP and to demonstrate the effectiveness of its system. This entails pushing back against what it sees as pressure from liberal democratic countries that could thwart its objectives. For its part, the United States worries about the negative externalities of Chinese authoritarianism, such as censorship of international criticism of Beijing or the export of its tools of repression to other countries.

The United States also worries about what would happen to the military balance of power if China secured an enduring advantage in key technologies.

Even in diplomacy, friction will be endemic to the U.S.-Chinese relationship and will affect the broader international order for the foreseeable future. Outright confrontation can be avoided—but competition cannot. 

This competition places real limits on cooperation. Take the arena of global public health: many studies on how to improve pandemic preparedness call on world leaders to dramatically strengthen the WHO, including by giving it the same power to enforce international health regulations as the International Atomic Energy Agency enjoys with nuclear nonproliferation rules

The problem is getting every government to agree to a universally applicable mechanism for sanctions or some other enforcement mechanism. China will not agree to any reform that would involve intrusive inspections of its scientific research facilities.

The need for cooperation on transnational threats must change how the United States competes with China—not whether it competes.

U.S. officials should not give up on China entirely; instead, they should make a good-faith effort to work with Beijing, both bilaterally and in multilateral settings. Recognizing that there are strict limits on U.S.-Chinese cooperation is not the same as saying that no cooperation is possible.

the real challenge is determining what to do when cooperation with China and other rivals falls short of what is required. The United States needs a backup plan to tackle shared challenges through coalitions of the willing.

When it comes to pandemic preparedness, this means fully supporting the WHO (including by pressing for needed reforms) but also forging a coalition of like-minded states: a global alliance for pandemic preparedness that would regularly convene at the head-of-state level and work alongside nongovernmental organizations and the private sector.

Crucially, whenever the WHO declared an international public health emergency, alliance members would coordinate on travel and trade restrictions, as well as on public messaging and financial penalties and sanctions. Those penalties and sanctions would be aimed at those states that failed to provide sufficient access to or fully cooperate with the WHO. The alliance would support, not supplant, the WHO.

Sustained, managed competition with China could potentially help the United States build bipartisan support for investments in clean technology that would prevent Beijing from gaining an enduring advantage in this area.

ut the United States and the European Union will also need to build coalitions of the willing to deal with the international security consequences of accelerated climate change, such as extreme weather events that threaten large numbers of people, and to address the foreign policy dimensions of climate action, including managing the risk that a shift away from fossil fuels could destabilize countries and regions that are dependent on oil exports.

Cooperation across this divide should always be the first choice in times of shared crisis, but as the COVID-19 pandemic has demonstrated, the U.S.-led constellation must always have a backup plan. It did not have one in 2020. It needs one for the next crisis

The need to let the Baltic states go was clear—and when they left the Soviet Union in 1990, Solzhenitsyn, Yeltsin and most of Russia rallied against revanchist attempts to keep them in. Much the same was true of Central Asia and the Caucasus; they were colonies. Belarus and Ukraine were part of the metropolitan core. The bonds which tied “Little Russians” (ie Ukrainians), “Great Russians” and Belarusians together, Solzhenitsyn argued, must be defended by all means short of war.

The agreement reached, in draft form, at 4am on Sunday morning achieved those aims with a rather neat piece of casuistry. For Russia simply to have followed Ukraine into independence would have left moot the question of the Soviet Union’s residual powers. So instead they abolished the union itself.

“the Kyivan myth of origins…became the cornerstone of Muscovy’s ideology as the polity evolved from a Mongol dependency to a sovereign state and then an empire.” Russian empire required Ukraine; and Russia had no history other than one of empire. The idea of Kyiv as just the capital of a neighbouring country was unimaginable to Russians.

When, as the economy worsened, Mr Gorbachev went to President George Bush for $10bn-15bn, Bush’s top concern was the nuclear threat. The same worry had led him to oppose Ukraine’s secession in a speech given just before the August coup. “Do you realise what you’ve done?” Mr Gorbachev demanded of Mr Shushkevich. “Once Bush finds out about this, what then?”

Yeltsin was overcome by a sense of lightness and freedom. “In signing this agreement,” he later recalled, “Russia was choosing a different path, a path of internal development rather than an imperial one…She was throwing off the traditional image of ‘potentate of half the world’, of armed conflict with Western civilisation, and the role of policeman in the resolution of ethnic conflicts. The last hour of the Soviet empire was chiming.” Maybe the convoluted interdependency of Russia and Ukraine did not matter as much as people thought; maybe democratic nationhood was enough. Maybe the problem had been a failure of imagination.

But when pollsters asked people what they expected of their incoming president, reducing this corruption was not their highest priority. The standing of the state was. Russians wanted a strong state and one respected abroad. As Mr Putin’s successful manifesto put it,

The strong state which provided an effective cover for kleptocracy in Mr Putin’s Russia was not an option for Mr Kuchma’s similarly oligarchic Ukraine. It had no real history as a state, let alone a strong one. Its national myth was one of Cossacks riding free. So in Ukraine the stealing was instead dressed up in terms of growing into that distinctive national identity. The essence of the argument was simple. As Mr Kuchma put it in a book published in 2003, “Ukraine is not Russia”.

Mr Kuchma could have used force against them; Mr Putin encouraged him to do so. But various considerations, including Western opprobrium, argued against it.

Mr Putin’s return to the presidency in 2012 came at a time when the global financial crisis had choked the Russian economy.

The degree to which Ukraine was not Russia became clearer, though, in 2004, when a rigged presidential election saw hundreds of thousands of Ukrainians protesting in the streets.

Mr Yanukovych did not want to be Russia’s vassal. Nor did he share western Europe’s values—especially when applied to matters of anti-corruption. But eventually he had to choose a side. At a secret meeting in Moscow in November 2013, as European leaders were preparing to sign their agreement with Ukraine, he was promised a $15bn credit line with $3bn paid up front. He ditched the European deal. And at 4am on November 30th his goons bludgeoned a few dozen students protesting against his betrayal in Kyiv’s Independence Square, known as Maidan.

This was far worse, for Mr Putin, than the Orange revolution. Ukraine had made geopolitical reality, to coin a phrase, of the independence it had claimed two decades before. Its demands for dignity resonated with Russia’s middle class and some of its elite, making it a genuinely dangerous example. So Mr Putin annexed Crimea and started a war in Donbas.

According to Russian state media, Mr Putin was not undermining a revolution against a corrupt regime quite like his own; he was protecting the Russian people and language from extermination at the hands of western Ukrainian fascists. The relevance to Russia of the issues that had led to what was being called in Ukraine “the revolution of dignity” was thus obscured

the annexation was supported by nearly 90% of the Russian population.

tract published in both Russian, Ukrainian and English in July 2021, Mr Putin described how the inheritors of “Ancient Rus” had been torn apart by hostile powers and treacherous elites, and how Ukraine had been turned from being “not Russia” into an anti-Russia, an entity fundamentally incompatible with Russia’s goals.

The only way Russia can escape chaos, he argued, is to export it to a neighbouring country.

Ukraine is not a province, or a colony; it is a beleaguered nation in a messy, perilous process of self-realisation. Belarus, for its part, is a grim illustration of how “severe and inflexible” things have to get in order to stop such aspirations welling up. Mr Lukashenko has met a nationalist resurgence with ever more brutal and well-orchestrated repression—a bloody irony given that he helped start it.

But change is afoot; it can be seen in the way that demography increasingly trumps regional allegiance. Even in the east nearly 60% of those born since 1991 see their future as in the EU—countrywide, the figure is 75%. All told 90% want Ukraine to stay independent, and nearly 80% are optimistic about its future.

That is why Alexei Navalny was first poisoned and is now jailed. As the leader of the opposition to Mr Putin he has championed the idea of Russia not as an empire but as a civic nation: a state for the people. It is why Russia has recently become much more repressive. It is why Mr Putin cannot tolerate a true peace on his borders.

The various peaks represent times in which each nation was hit by a new Covid wave, including the initial outbreak and influx of hospital patients, last winter's surge or the summer spike caused by the Delta variant.

Hospitals around the US have reported that the spike in infected patients has exacerbated pressure on facilities already strained by the pandemic.Dr Juan Reyes, the director of hospital medicine at George Washington University in Washington DC - which is among the US cities with the highest per capita hospital admissions rate - said that this surge "has been a lot more challenging" than previous ones.

In South Africa - where the Omicron variant was first detected in November - researchers found that those infected with Omicron are less likely to be sent to hospital and more likely to recover quickly.

Let's begin with this chart comparing how many people in several countries have been in hospital with Covid-19 during the pandemic. It's adjusted to account for population size and represents a ratio of the number of infected hospital patients per million inhabitants.

"The seasonality is also different," he said. "Omicron's surge through South Africa was during their summer,

Just over 63% of the US population is fully vaccinated, much lower than in the UK (71%) as well as Italy and France (both 75%). In Canada, almost 79% of the population is fully protected.

"incongruent" public health policy when it comes to Covid-19."In other words, there isn't a single unified method in how we're going to do things across the board," he said. "It's more regional than national, and because of that you have gaps. The consequences of that are people getting hospitalised."

the true figure is hard to determine."We don't know how much Delta there is," she told the BBC. "What the US has started to do is look at the number of new infections and sequences. Omicron is 95% of new infections, but we don't know how much Delta we still have around."

In many countries, researchers believe that the Omicron variant has begun to subside, possibly signalling the end of the increase in hospital patients with Covid.

"It still could make for a miserable winter," Dr Gandhi said. "I think that for the next month, life is going to be really hard in schools and hospitals

The kunga is the first known instance of a human-engineered hybrid of two species, a production far beyond the traditional processes of the domestication of animals, the researchers found.

Like mules, which are hybrids between horses and donkeys, and which were created much later, the kungas were sterile. Each new kunga was a one-off, a mating between a wild ass stallion and a donkey.

The stallions had to be captured and kept in captivity, even though they were highly aggressive, as modern records have indicated.

Kungas held their high status for at least 500 years, Dr. Geigl said. Horses did not appear until around 4,000 years ago to take their place in battle and ceremony, and to contribute to the creation of other hybrids. Before the current research, the oldest known hybrid was a mule from a site in Turkey dating to 3,000 years ago. Members of the same team reported on that find in 2020.

the “results were very convincing,” showing that people “were experimenting with hybrid equids long before the arrival of the horse.”

Fiona Marshall, an archaeologist at Washington University in St. Louis, who has researched the prehistory of donkeys and their domestication, said the study was “enormously significant” partly because it showed that the breeders had clear intentions. The early process of domestication was always murky — probably part accident, part human intervention — but this research showed what the ancient Syrians were after.

“People wanted the qualities of a wild animal,” she said. Donkeys might have been tamer than their ancestors, the African wild ass, but the breeders in Mesopotamia wanted to back breed to other wild asses for strength and speed — and perhaps size.

the team sequenced DNA from numerous sources, including modern donkeys, horses and several species of wild asses, and museum samples.

Of particular importance were the bones of 44 kungas interred at a rich burial site in Syria called Umm el-Marra. Those skeletons had earlier led Dr. Weber and others to hypothesize that they were hybrids and that they were the kungas described in tablets and represented in art.

Their teeth showed bit marks and indicated they had been fed a special diet.

Donkeys are plentiful, of course, but the last known Syrian wild asses died in the late 1920s.

“The recipe for making the kunga was unknown for thousands of years,” Dr. Bennett said. “And we finally decode it not even 100 years since one element has become extinct.”

in the early 1340s, the disease had struck China, India, Persia, Syria and Egypt.

They know that the bacillus travels from person to person pneumonically, or through the air, as well as through the bite of infected fleas and rats.

The Black Death was terrifyingly, indiscriminately contagious

Today, scientists understand that the Black Death, now known as the plague, is spread by a bacillus called Yersina pestis.

However, Europeans were scarcely equipped for the horrible reality of the Black Death.

Not long after it struck Messina, the Black Death spread to the port of Marseilles in France and the port of Tunis in North Africa

Then it reached Rome and Florence, two cities at the center of an elaborate web of trade routes.

Today, this grim sequence of events is terrifying but comprehensible

No one knew exactly how the Black Death was transmitted from one patient to another, and no one knew how to prevent or treat it

Meanwhile, in a panic, healthy people did all they could to avoid the sick

Because they did not understand the biology of the disease, many people believed that the Black Death was a kind of divine punishment – retribution for sins against God such as greed, blasphemy, heresy, fornication and worldliness.

Ukraine is also receiving vital private-sector assistance, notably the delivery of Starlink internet terminals, which are helping maintain communications

All I can do is to apply history, as there is no model from political science or economics that can really help us here.

1. Do the Russians manage to take Kyiv in a matter of two, three, four weeks or never?

At least one military analyst I respect said late last week that the Russian invasion force has around two weeks left before serious logistical and supply problems force Putin seriously to the negotiating table.

On the other hand, Western media seem over-eager to cover news of Russian reverses, and insufficiently attentive to the harsh fact that the invaders continue to advance on more than one front.

A better analogy than the Winter War with Finland may be the Soviet invasion of Afghanistan that began in December 1979.

Economic warfare between 1914 and 1918 was not a substitute for sending British armies to fight on the European continent, just as it had not been in the Napoleonic Wars against France.

What I cannot tell is whether or not these weapons and other equipment will suffice to sustain Ukrainian resistance over the coming weeks.

But the Ukrainians have no real answers to higher-altitude bombardment and missile attacks.

2. Do the sanctions precipitate such a severe economic contraction in Russia that Putin cannot achieve victory?

I have heard it said that the breadth and depth of the sanctions imposed on Russia make them unprecedented. I disagree

recalls but does not quite match the sanctions that Britain and its allies imposed on Germany at the outbreak of World War

It seems there are seven distinct historical processes at work and it’s not clear which is going fastest.

Then, as now, it was possible for an increasingly authoritarian government to impose economic controls and divert resources away from civilian consumption to the war effort, while blaming the resulting deprivation on the enemy

We should remember that those measures did not defeat Germany, however, because — like Russia today — it had the resources to be self-sufficient

no one should forget that self-sufficiency is possible for Russia, albeit at the price of severe austerity, whether it is a choice or a consequence of war.

China is able to help Russia in ways that could mitigate the economic shock, just as for years it has helped Iran to circumvent U.S. sanctions by buying its oil.

Unlike Soviet citizens, who were accustomed to a state monopoly on communications, today’s Russians have come to rely as much as we do on Big Tech. Being cut off from the metaverse may prove a more psychologically painful deprivation than shortages of imported foods.

even a 35% quarterly decline in gross domestic product does not condemn a country to military defeat if its planes can still fly and its tanks still fire rounds.

3. Does the combination of military and economic crisis precipitate a palace coup against Putin?

4. Does the risk of downfall lead Putin to desperate measures (carrying out his nuclear threat)? 

The people with the power to arrest Putin are the people he counts on to execute his arrest orders: Nikolai Patrushev, the head of the Security Council and, like Putin, a long-serving KGB officer; Sergei Naryshkin, the head of foreign intelligence; and Alexander Bortnikov, who heads the Federal Security Service, the successor to the KGB.

6. Does the West’s attention deficit disorder kick in before any of this?

If Putin’s goal was to deter members of NATO from offering direct military assistance to Ukraine, it seemed to have some effect.

Russian casualties are being caused by Ukrainians using arms supplied by multiple NATO countries, including the U.S. and Turkey, but they are mostly crossing into Ukraine from Poland. Might Putin therefore strike a target in eastern Poland — Lublin, say, or Przemysl?

he is surely more likely to do so if believes the U.S. would not immediately retaliate in kind against a Russian target. A key lesson of this entire crisis has been that indications of weakness on the U.S. side, which I discussed here last week, have emboldened Putin.

5. Do the Chinese keep Putin afloat but on the condition that he agrees to a compromise peace that they offer to broker?

My guess is that the Chinese make no serious diplomatic move until they are convinced Putin’s invasion is thoroughly bogged down in Ukraine’s spring mud.

I would not bet the fate of Ukraine on Russian internal politics.

Remarkably, one U.S. legislator told me last week that he “couldn’t recall an issue more obsessively followed and more unifying among” his constituents.

The only real significance of Western public outrage at Putin’s actions is the political pressure it exerts on Biden and other leaders to take a tougher line with Russia.

7. What is the collateral damage?

History shows that wars (much more than pandemics) are the most common cause of jumps in inflation.

The best-known recent illustration is the way wars in 1973 (Yom Kippur) and 1979 (Iran-Iraq) contributed to the great inflation of the Seventies

these price spikes are not confined to oil and gas but involve a host of other commodities. The prospect of this year’s Ukrainian grain harvest being disrupted means a significant surge in food prices, with all kinds of consequences, especially in developing countries.

A tsunami of war has struck Ukraine. Whether the Russian tide flows or ebbs in the coming weeks will do much to determine the course of world history for the rest of our lives.

Nor can we ignore the risks that may be lurking within the international financial system.

This is the first big crisis of Cold War II, which is in many ways like a mirror image of Cold War I, with China the senior partner, Russia the junior, and a hot war in Eastern Europe rather than East Asia (it was Korea’s turn in 1950).

I do not know how the crisis will turn out, but I do know it will have profound consequences for the course of the superpower contest.

If the invasion of Ukraine ends in disaster for the heroic defenders of Kyiv and their comrades, another disaster may well follow — and it could occur as far away as Taiwan. Conversely, if there is justice in the world and the disaster befalls the architect of this war, that too will give birth to some fresh and unforeseeable event.

Add these seven imponderables together and you see how profoundly important the next few weeks will be.

The failure of the administration to signal that it would retaliate is of a piece with last year’s reports that Biden’s national security team was considering ruling out first use of nuclear weapons in its new national military strategy. Nuclear missiles cease to be a deterrent if one side is unwilling to use them.

Today, however, the boot is on the other foot. Not only is Putin intimidating NATO; he may have achieved something more, namely a tacit admission by the Biden administration that it would not necessarily retaliate with nuclear weapons if Russia used them.

that’s particularly true on the I.R.A., which has to build all these things in the real world.

we’re trying to do industrial physical transformation at a speed and scale unheralded in American history. This is bigger than anything we have done at this speed ever.

The money is beginning to move out the door now, but we’re on a clock. Climate change is not like some other issues where if you don’t solve it this year, it is exactly the same to solve it next year. This is an issue where every year you don’t solve it, the amount of greenhouse gases in the atmosphere builds, warming builds, the effects compound

Solve, frankly, isn’t the right word there because all we can do is abate, a lot of the problems now baked in. So how is it going, and who can actually walk us through that?

Robinson Meyer is the founding executive editor of heatmap.news

why do all these numbers differ so much? How big is this thing?

in electric vehicles and in the effort, kind of this dual effort in the law, to both encourage Americans to buy and use electric vehicles and then also to build a domestic manufacturing base for electric vehicles.

on both counts, the data’s really good on electric vehicles. And that’s where we’re getting the fastest response from industry and the clearest response from industry to the law.

ROBINSON MEYER: Factories are getting planned. Steel’s going in the ground. The financing for those factories is locked down. It seems like they’re definitely going to happen. They’re permitted. Companies are excited about them. Large Fortune 500 automakers are confidently and with certainty planning for an electric vehicle future, and they’re building the factories to do that in the United States. They’re also building the factories to do that not just in blue states. And so to some degree, we can see the political certainty for electric vehicles going forward.

in other parts of the law, partially due to just vagaries of how the law is being implemented, tax credits where the fine print hasn’t worked out yet, it’s too early to say whether the law is working and how it’s going and whether it’s going to accomplish its goal

EZRA KLEIN: I always find this very funny in a way. The Congressional Budget Office scored it. They thought it would make about $380 billion in climate investments over a decade. So then you have all these other analyses coming out.

But there’s actually this huge range of outcomes in between where the thing passes, and maybe what you wanted to have happen happens. Maybe it doesn’t. Implementation is where all this rubber meets the road

the Rhodium Group, which is a consulting firm, they think it could be as high as $522 billion, which is a big difference. Then there’s this Goldman Sachs estimate, which the administration loves, where they say they’re projecting $1.2 trillion in incentives —

ROBINSON MEYER: All the numbers differ because most of the important incentives, most of the important tax credits and subsidies in the I.R.A., are uncapped. There’s no limit to how much the government might spend on them. All that matters is that some private citizen or firm or organization come to the government and is like, hey, we did this. You said you’d give us money for it. Give us the money.

because of that, different banks have their own energy system models, their own models of the economy. Different research groups have their own models.

we know it’s going to be wrong because the Congressional Budget Office is actually quite constrained in how it can predict how these tax credits are taken up. And it’s constrained by the technology that’s out there in the country right now.

The C.B.O. can only look at the number of electrolyzers, kind of the existing hydrogen infrastructure in the country, and be like, well, they’re probably all going to use these tax credits. And so I think they said that there would be about $5 billion of take up for the hydrogen tax credits.

But sometimes money gets allocated, and then costs overrun, and there delays, and you can’t get the permits, and so on, and the thing never gets built

the fact that the estimates are going up is to them early evidence that this is going well. There is a lot of applications. People want the tax credits. They want to build these new factories, et cetera.

a huge fallacy that we make in policy all the time is assuming that once money is allocated for something, you get the thing you’re allocating the money for. Noah Smith, the economics writer, likes to call this checkism, that money equals stuff.

EZRA KLEIN: They do not want that, and not wanting that and putting every application through a level of scrutiny high enough to try and make sure you don’t have another one

I don’t think people think a lot about who is cutting these checks, but a lot of it is happening in this very obscure office of the Department of Energy, the Loan Program Office, which has gone from having $40 billion in lending authority, which is already a big boost over it not existing a couple decades ago, to $400 billion in loan authority,

the Loan Program Office as one of the best places we have data on how this is going right now and one of the offices that’s responded fastest to the I.R.A.

the Loan Program Office is basically the Department of Energy’s in-house bank, and it’s kind of the closest thing we have in the US to what exists in other countries, like Germany, which is a State development bank that funds projects that are eventually going to be profitable.

It has existed for some time. I mean, at first, it kind of was first to play after the Recovery Act of 2009. And in fact, early in its life, it gave a very important loan to Tesla. It gave this almost bridge loan to Tesla that helped Tesla build up manufacturing capacity, and it got Tesla to where it is today.

EZRA KLEIN: It’s because one of the questions I have about that office and that you see in some of the coverage of them is they’re very afraid of having another Solyndra.

Now, depending on other numbers, including the D.O.E., it’s potentially as high as $100 billion, but that’s because the whole thing about the I.R.A. is it’s meant to encourage the build-out of this hydrogen infrastructure.

EZRA KLEIN: I’m never that excited when I see a government loans program turning a profit because I think that tends to mean they’re not making risky enough loans. The point of the government should be to bear quite a bit of risk —

And to some degree, Ford now has to compete, and US automakers are trying to catch up with Chinese EV automakers. And its firms have EV battery technology especially, but just have kind of comprehensive understanding of the EV supply chain that no other countries’ companies have

ROBINSON MEYER: You’re absolutely right that this is the key question. They gave this $9.2 billion loan to Ford to build these EV battery plants in Kentucky and Tennessee. It’s the largest loan in the office’s history. It actually means that the investment in these factories is going to be entirely covered by the government, which is great for Ford and great for our build-out of EVs

And to some degree, I should say, one of the roles of L.P.O. and one of the roles of any kind of State development bank, right, is to loan to these big factory projects that, yes, may eventually be profitable, may, in fact, assuredly be profitable, but just aren’t there yet or need financing that the private market can’t provide. That being said, they have moved very slowly, I think.

And they feel like they’re moving quickly. They just got out new guidelines that are supposed to streamline a lot of this. Their core programs, they just redefined and streamlined in the name of speeding them up

However, so far, L.P.O. has been quite slow in getting out new loans

I want to say that the pressure they’re under is very real. Solyndra was a disaster for the Department of Energy. Whether that was fair or not fair, there’s a real fear that if you make a couple bad loans that go bad in a big way, you will destroy the political support for this program, and the money will be clawed back, a future Republican administration will wreck the office, whatever it might be. So this is not an easy call.

when you tell me they just made the biggest loan in their history to Ford, I’m not saying you shouldn’t lend any money to Ford, but when I think of what is the kind of company that cannot raise money on the capital markets, the one that comes to mind is not Ford

They have made loans to a number of more risky companies than Ford, but in addition to speed, do you think they are taking bets on the kinds of companies that need bets? It’s a little bit hard for me to believe that it would have been impossible for Ford to figure out how to finance factorie

ROBINSON MEYER: Now, I guess what I would say about that is that Ford is — let’s go back to why Solyndra failed, right? Solyndra failed because Chinese solar deluged the market. Now, why did Chinese solar deluge the market? Because there’s such support of Chinese financing from the state for massive solar factories and massive scale.

EZRA KLEIN: — the private market can’t. So that’s the meta question I’m asking here. In your view, because you’re tracking this much closer than I am, are they too much under the shadow of Solyndra? Are they being too cautious? Are they getting money out fast enough?

ROBINSON MEYER: I think that’s right; that basically, if we think the US should stay competitive and stay as close as it can and not even stay competitive, but catch up with Chinese companies, it is going to require large-scale state support of manufacturing.

EZRA KLEIN: OK, that’s fair. I will say, in general, there’s a constant thing you find reporting on government that people in government feel like they are moving very quickly

EZRA KLEIN: — given the procedural work they have to go through. And they often are moving very quickly compared to what has been done in that respect before, compared to what they have to get over. They are working weekends, they are working nights, and they are still not actually moving that quickly compared to what a VC firm can do or an investment bank or someone else who doesn’t have the weight of congressional oversight committees potentially calling you in and government procurement rules and all the rest of it.

ROBINSON MEYER: I think that’s a theme across the government’s implementation of the I.R.A. right now, is that generally the government feels like it’s moving as fast as it can. And if you look at the Department of Treasury, they feel like we are publishing — basically, the way that most of the I.R.A. subsidies work is that they will eventually be administered by the I.R.S., but first the Department of the Treasury has to write the guidebook for all these subsidies, right?

the law says there’s a very general kind of “here’s thousands of dollars for EVs under this circumstance.” Someone still has to go in and write all the fine print. The Department of Treasury is doing that right now for each tax credit, and they have to do that before anyone can claim that tax credit to the I.R.S. Treasury feels like it’s moving extremely quickly. It basically feels like it’s completely at capacity with these, and it’s sequenced these so it feels like it’s getting out the most important tax credits first.

Private industry feels like we need certainty. It’s almost a year since the law passed, and you haven’t gotten us the domestic content bonus. You haven’t gotten us the community solar bonus. You haven’t gotten us all these things yet.

a theme across the government right now is that the I.R.A. passed. Agencies have to write the regulations for all these tax credits. They feel like they’re moving very quickly, and yet companies feel like they’re not moving fast enough.

that’s how we get to this point where we’re 311 days out from the I.R.A. passing, and you’re like, well, has it made a big difference? And I’m like, well, frankly, wind and solar developers broadly don’t feel like they have the full understanding of all the subsidies they need yet to begin making the massive investments

I think it’s fair to say maybe the biggest bet on that is green hydrogen, if you’re looking in the bill.

We think it’s going to be an important tool in industry. It may be an important tool for storing energy in the power grid. It may be an important tool for anything that needs combustion.

ROBINSON MEYER: Yeah, absolutely. So green hydrogen — and let’s just actually talk about hydrogen broadly as this potential tool in the decarbonization tool kit.

It’s a molecule. It is a very light element, and you can burn it, but it’s not a fossil fuel. And a lot of the importance of hydrogen kind of comes back to that attribute of it.

So when we look at sectors of the economy that are going to be quite hard to decarbonize — and that’s because there is something about fossil fuels chemically that is essential to how that sector works either because they provide combustion heat and steelmaking or because fossil fuels are actually a chemical feedstock where the molecules in the fossil fuel are going into the product or because fossil fuels are so energy dense that you can carry a lot of energy while actually not carrying that much mass — any of those places, that’s where we look at hydrogen as going.

green hydrogen is something new, and the size of the bet is huge. So can you talk about first just what is green hydrogen? Because my understanding of it is spotty.

The I.R.A. is extremely generous — like extremely, extremely generous — in its hydrogen subsidies

The first is for what’s called blue hydrogen, which is hydrogen made from natural gas, where we then capture the carbon dioxide that was released from that process and pump it back into the ground. That’s one thing that’s subsidized. It’s basically subsidized as part of this broader set of packages targeted at carbon capture

green hydrogen, which is where we take water, use electrolyzers on it, basically zap it apart, take the hydrogen from the water, and then use that as a fue

The I.R.A. subsidies for green hydrogen specifically, which is the one with water and electricity, are so generous that relatively immediately, it’s going to have a negative cost to make green hydrogen. It will cost less than $0 to make green hydrogen. The government’s going to fully cover the cost of producing it.

That is intentional because what needs to happen now is that green hydrogen moves into places where we’re using natural gas, other places in the industrial economy, and it needs to be price competitive with those things, with natural gas, for instance. And so as it kind of is transported, it’s going to cost money

As you make the investment to replace the technology, it’s going to cost money. And so as the hydrogen moves through the system, it’s going to wind up being price competitive with natural gas, but the subsidies in the bill are so generous that hydrogen will cost less than $0 to make a kilogram of it

There seems to be a sense that hydrogen, green hydrogen, is something we sort of know how to make, but we don’t know how to make it cost competitive yet. We don’t know how to infuse it into all the processes that we need to be infused into. And so a place where the I.R.A. is trying to create a reality that does not yet exist is a reality where green hydrogen is widely used, we have to know how to use it, et cetera.

And they just seem to think we don’t. And so you need all these factories. You need all this innovation. Like, they have to create a whole innovation and supply chain almost from scratch. Is that right?

ROBINSON MEYER: That’s exactly right. There’s a great Department of Energy report that I would actually recommend anyone interested in this read called “The Liftoff Report for Clean Hydrogen.” They made it for a few other technologies. It’s a hundred-page book that’s basically how the D.O.E. believes we’re going to build out a clean hydrogen economy.

And, of course, that is policy in its own right because the D.O.E. is saying, here is the years we’re going to invest to have certain infrastructure come online. Here’s what we think we need. That’s kind of a signal to industry that everyone should plan around those years as well.

It’s a great book. It’s like the best piece of industrial policy I’ve actually seen from the government at all. But one of the points it makes is that you’re going to make green hydrogen. You’re then going to need to move it. You’re going to need to move it in a pipeline or maybe a truck or maybe in storage tanks that you then cart around.

Once it gets to a facility that uses green hydrogen, you’re going to need to store some green hydrogen there in storage tanks on site because you basically need kind of a backup supply in case your main supply fails. All of those things are going to add cost to hydrogen. And not only are they going to add cost, we don’t really know how to do them. We have very few pipelines that are hydrogen ready.

All of that investment needs to happen as a result to make the green hydrogen economy come alive. And why it’s so lavishly subsidized is to kind of fund all that downstream investment that’s eventually going to make the economy come true.

But a lot of what has to happen here, including once the money is given out, is that things we do know how to build get built, and they get built really fast, and they get built at this crazy scale.

So I’ve been reading this paper on what they call “The Greens’ Dilemma” by J.B. Ruhl and James Salzman, who also wrote this paper called “Old Green Laws, New Green Deal,” or something like that. And I think they get at the scale problem here really well.
