When New York City announced on Tuesday that it would soon require people to show proof of at least one coronavirus vaccine shot to enter businesses, Mayor Bill de Blasio said the system was “simple — just show it and you’re in.”
Less simple was the privacy debate that the city reignited.
Vaccine passports, which show proof of vaccination, often in electronic form such as an app, are the bedrock of Mr. de Blasio’s plan. For months, these records — also known as health passes or digital health certificates — have been under discussion around the world as a tool to allow vaccinated people, who are less at risk from the virus, to gather safely. New York will be the first U.S. city to include these passes in a vaccine mandate, potentially setting off similar actions elsewhere.
But the mainstreaming of these credentials could also usher in an era of increased digital surveillance, privacy researchers said. That’s because vaccine passes may enable location tracking, even as there are few rules about how people’s digital vaccine data should be stored and how it can be shared. While existing privacy laws limit the sharing of information among medical providers, there is no such rule for when people upload their own data onto an app.

passed a law limiting such use only to “serious” criminal investigations.
“One of the things that we don’t want is that we normalize surveillance in an emergency and we can’t get rid of it,” said Jon Callas, the director of technology projects at the Electronic Frontier Foundation, a digital rights group.
While such incidents are not occurring in the United States, researchers said, they already see potential for overreach. Several pointed to New York City, where proof of vaccination requirements will start on Aug. 16 and be enforced starting on Sept. 13.
For proof, people can use their paper vaccination cards, the NYC Covid Safe app or another app, the Excelsior Pass. The Excelsior Pass was developed by IBM under an estimated $17 million contract with New York State.
To obtain the pass, people upload their personal information. Under the standard version of the pass, businesses and third parties see only whether the pass is valid, along with the person’s name and date of birth.
On Wednesday, the state announced the “Excelsior Pass Plus,” which displays not only whether an individual is vaccinated, but includes more information about when and where they got their shot. Businesses scanning the Pass Plus “may be able to save or store the information contained,” according to New York State.
Phase 2,” which could involve expanding the app’s use and adding more information like personal details and other health records that could be checked by businesses upon entry.
IBM has said that it uses blockchain technology and encryption to protect user data, but did not say how. The company and New York State did not respond to requests for comment.
Mr. de Blasio told WNYC in April that he understands the privacy concerns around the Excelsior Pass, but thinks it will still “play an important role.”
For now, some states and cities are proceeding cautiously. More than a dozen states, including Arizona, Florida and Texas, have in recent months announced some type of ban on vaccine passports. The mayors of San Francisco, Los Angeles and Seattle have also said they were holding off on passport programs.
Some business groups and companies that have adopted vaccine passes said the privacy concerns were valid but addressable.
Airlines for America, an industry trade group, said it supported vaccine passes and was pushing the federal government to establish privacy standards. The San Francisco Chamber of Commerce, which is helping its members work with Clear, said using the tools to ensure only vaccinated people entered stores was preferable to having businesses shut down again as virus cases climb.
“People’s privacy is valuable,” said Rodney Fong, the chamber’s president, but “when we’re talking about saving lives, the privacy piece becomes a little less important.”
BERLIN — As concerns grow over the highly contagious Delta variant of the coronavirus, Germany on Monday became the biggest Western country yet to announce that it will offer vaccine booster shots to a wide range of people considered potentially vulnerable, adding to growing momentum in rich nations to give additional shots to fully vaccinated people.
The move by Germany came even as a top European Union official criticized the bloc as falling far short of its promises to donate vaccine doses to Africa and Latin America. And with a limited global vaccine supply, health experts say the top priorities should be distributing doses to poor countries that lag far behind in inoculations, and persuading vaccine-resistant people in wealthy countries to get their first shots.
There is also still no consensus among scientists on the need for booster shots, but as fears rise of more pandemic waves and more costly lockdowns, a growing number of countries are preparing to give their people booster doses — or have already started.
Starting in September, Germany, Europe’s largest economy, wants to administer a booster of the Pfizer-BioNTech or Moderna vaccine to older people, residents of care homes, and people with compromised immune systems — and also to anyone who was already fully vaccinated with the two-dose AstraZeneca or single-dose Johnson & Johnson shots, which clinical trials have shown are not as highly protective.
an early leader in vaccination, began administering boosters to people 60 and older last week. A month ago, Russia made additional shots available to anyone six months after inoculation, and on Sunday, Hungary began offering them four months post-vaccination.
France is offering them only to those with weak immune systems, and plans to give them this fall to those who were the first to be vaccinated early this year — mostly people over 75 and those with serious health problems.
government advisers recommended in late June that everyone over 50 should be eligible but said the priority should be getting the shots to people over 70, health workers, nursing home residents, and younger adults with immune problems or other serious vulnerabilities.
increasingly think that vulnerable populations may need additional shots even as research continues into how long the vaccines remain effective. Some people have already obtained boosters simply by not revealing previous vaccination.
But as governments, terrified of another surge in the virus, increasingly lean toward boosters, the need for them remains unclear.
Studies have indicated that immunity resulting from the Pfizer-BioNTech and Moderna vaccines is long-lasting, and researchers are still working to interpret recent Israeli data suggesting a decline in efficacy of the Pfizer-BioNTech vaccine months after inoculation.
although the vaccine remains powerfully effective against severe disease and death.
Experts were divided on the utility of booster shots so soon after vaccination began. Experience with other diseases indicates that older people and those with weak immune systems might benefit, but there is little hard evidence with the coronavirus.
“The problem here is, we’re just sort of going on immunological priors, rather than really great data to justify things one way or the other,” said Deepta Bhattacharya, an immunologist at the University of Arizona. “I totally understand the decision, but I think we have to acknowledge that there’s a wide range of uncertainty on what it’s going to do.”
Booster doses may help some people with weak immune systems, but others may show little improvement even after a third dose, and still others may not need a booster at all, scientists say.
While dozens of mostly wealthy countries, including the United States and most of Europe, have administered more than 100 doses per 100 people, many other nations remain below five per 100 — primarily in Africa, where cases have soared as the Delta variant spreads.

Doctors Without Borders said recently that it would be “unconscionable” to give booster doses in richer nations before people in poorer ones get their first doses.
“Wealthy governments shouldn’t be prioritizing giving third doses when much of the developing world hasn’t even yet had the chance to get their first Covid-19 shots,” Kate Elder, the senior vaccines policy adviser at Doctors Without Borders’ Access Campaign, said in a statement.
a so-called vector vaccine, like AstraZeneca or Johnson & Johnson.
It is the latest sign that governments are encouraging their citizens to mix and match vaccines in the hope of provoking a more protective immune response against Covid-19. Early results from a British vaccine study showed that volunteers produced high levels of antibodies and immune cells after getting one dose each of the Pfizer-BioNTech and AstraZeneca-Oxford shots.
The new German guidelines announced Monday also went a step further in encouraging parents to vaccinate children between 12 and 17, announcing that doctors and vaccination centers across the country would make the jab available to them before the start of the new school year.
Health ministers stopped short of making a formal recommendation for vaccinating children, but the move made plain their impatience with Germany’s Standing Committee on Vaccinations, which has so far refrained from guiding parents one way or the other, pending more data becoming available.
Vaccinating children “is one building block to allow a safe start into the new school year after the summer vacation,” Mr. Holetschek said.

an ambitious proposal to cut carbon emissions, how will those who hope to succeed Chancellor Angela Merkel respond?
If only because of their sheer scale, analysts say, the floods are likely to play a significant role for voters when they go to the polls on Sept 26 to replace Ms. Merkel, who has led the country for 16 years.
The death toll in Germany climbed to at least 143 on Saturday, while the toll across the border in Belgium stood at 27, its national crisis center said. The count rose most sharply in Germany’s Ahrweiler district in Rhineland-Palatinate State, where the police said that more than 90 people had died. The authorities feared that number could yet grow.
In Germany, Europe’s largest economy and a country that prides itself on its sense of stability, the chaos wrought by nature was likely to reverberate for months, if not years.
But on Saturday, residents and rescue workers in flood-hit areas faced the more immediate and daunting task of clearing piles of debris, unclogging roads and salvaging some of the homes that had survived the deluge.
Hundreds of people remain unaccounted for, but officials have struggled to offer precise numbers.
Electricity and telephone services remain inaccessible in parts of Germany, and some roads are still impassable. That lack of access may account for the high tallies of those still considered missing. And some of those who are not accounted for could simply be away, on vacation or work assignment. In Belgium, police officers started knocking on doors to try to confirm the whereabouts of residents.
Still, officials said they expected to find additional victims.
Extreme downpours like the ones that hit Germany are one of the most visible signs that the climate is changing as a result of global warming from greenhouse gas emissions. Studies have shown a warmer atmosphere can hold more moisture, generating more rainfall.
Floods of this size have not been seen in 500 or even 1,000 years, according to meteorologists and German officials.
Rhineland-Palatinate was one of the two hardest-hit German states in the west, along with North Rhine-Westphalia. The Rhine River flows through the two regions, and the rain fell so rapidly that it engorged even small streams and tributaries not typically considered flood threats.

Germany’s president, Frank-Walter Steinmeier, traveled on Saturday to the town of Erftstadt, southwest of Cologne, where the flooding destroyed homes. Ms. Merkel planned to travel on Sunday to Schuld in Rhineland-Palatinate, which was badly hit, even as all of its 700 residents managed to survive.
There were scenes of devastation from all around Western Europe, the floods having caused damage from Switzerland to the Netherlands. But Germany was hardest hit.
Days before roiling waters tore through western Germany, a European weather agency had issued an extreme flood warning, as models showed that storms would send rivers surging to levels that had not been seen in hundreds of years.
The warnings, however, did little good.
Though Germany’s flood warning system, a network of sensors that measure river levels, functioned as it was supposed to, state and local officials said the amount of rain was unlike anything they had ever seen, causing even small streams and rivers to flood their banks.
Survivors and officials said many areas were caught unprepared as normally placid brooks and streams turned into torrents that swept away cars, houses and bridges. About 15,000 police officers, soldiers and emergency service workers have been deployed in Germany to help with the search and rescue.
Dr. Linda Speight, a hydrometeorologist at the University of Reading in Britain who studies how flooding occurs, blamed poor communication about the high risk posed by the flooding as contributing to the significant loss of life. “There should not have been so many deaths from this event,” she said.

Residents returning home, only to find their homes no longer there. Roads submerged by landslides. Loved ones still unaccounted for.
As the weather improved on Saturday and rescue workers searched for missing residents, many people in flood-hit areas of Germany were trying to re-establish some order amid the chaos and destruction.
Friends and relatives mobilized to help, maneuvering around blocked roads and washed-out bridges. Crushed cars and mounds of ruined goods were carted away, or piled by the side of muddied, cracked roads.
Many expressed amazement at how so much could have been destroyed so quickly. For Lisa Knopp, 19, who was helping to empty the flood-ruined basement of her grandmother’s home in Sinzig, a small town between the Rhine and Ahr rivers, the scenes of destruction “will stay with me a long time.”
Kim Falkenstein said her mother lost her home in Ahrweiler, one of the hardest-hit spots. Ms. Falkenstein, who was born in Ahrweiler and now lives in New York, said several friends had also lost their homes, and a classmate had died.
“I am heartbroken,” she said.
“Seeing my city being destroyed, people who I am close with losing their existence, and knowing I will never return to something I once called home,” Ms. Falkenstein said, “gives me goose bumps.”
In a country that is among Europe’s most prosperous, where orderliness is highly prized, many Germans were unnerved by the helplessness wrought by nature.
Bertrand Adams, a local official in Trier-Ehrang, a town in western Germany, stared in disbelief at the swirling waters only now receding from his community.
“It is beyond anything that could ever be imagined,” he told ZDF television. “We have a very good flood protection system that we developed only five years ago. We were so certain that nothing can go wrong.”
Daniela Schmitz, who has a ranch in Erftstadt, a town southwest of Cologne, was relieved that her property was not destroyed by the floods and that her horses had been evacuated. Others, she said, weren’t that fortunate.
“We were warned early enough — other stables are not doing so well,” she wrote in a WhatsApp message. “Many animals have drowned, entire stalls destroyed, and feed is becoming scarce. The conditions are really catastrophic in many places.”
On Saturday, German television channels carried wall-to-wall coverage of the flooding, as rescue workers continued searching for those who had been trapped by rising waters, with 143 confirmed dead in Germany and hundreds still missing.
As the official response picked up speed on Saturday, electricity, water and internet coverage were slowly being restored. Hundreds of police, fire and emergency vehicles crammed the roads into the most afflicted areas of Rhine-Palatinate and North Rhine-Westphalia.
“For a long time, chatting about the weather was synonymous with triviality. That’s over now,” Germany’s ARD public television said in its lead editorial on Friday. “The weather is highly political; there is hardly any nonpolitical weather anymore, especially not during an election campaign.”
The shift in the debate comes as the European Union has announced an ambitious blueprint to make the 27-country bloc carbon-neutral by 2050. No European country may be affected more than Germany, the continent’s largest economy.
Armin Laschet, 60, the conservative governor of North Rhine-Westphalia, who is looking to succeed Ms. Merkel in the Sept. 26 election, has lauded his regional government for passing legislation on climate change. But critics point to the open-pit soft coal mines operating in his state and his repeated emphasis on the importance of Germany remaining an industrial powerhouse.
Pressed in a television interview on whether the floods would prompt him to alter his climate policy, Mr. Laschet snapped at the moderator.
“I am a governor, not an activist,” he said. “Just because we have had a day like this does not mean we change our politics.”
Yet floods have a history of influencing political campaigns in Germany. In 2002, pictures of Chancellor Gerhard Schröder wading in rubber boots through streets awash in the muddy waters of the swollen Elbe, while his conservative rival remained on vacation, are credited with helping him win the election that year.
Perhaps wary of that lesson, Annalena Baerbock, the Greens party candidate for chancellor and Mr. Laschet’s strongest rival, cut short her vacation to visit stricken areas in Rhineland-Palatinate on Friday.
She called for immediate assistance for those affected, but also issued an appeal to better protect “residential areas and infrastructure” from extreme weather events, which she linked to the changing climate.
Whether the flooding will be enough to lift the party remains to be seen. After the Greens enjoyed an initial surge of excitement — Ms. Baerbock is the only woman running to replace the country’s first female chancellor — support for the party has dipped to around 20 percent in polls.
That puts the Greens in second place behind Mr. Laschet’s conservatives, who have been climbing to around 30 percent support, the latest surveys show.
Olaf Scholz, 63, Ms. Merkel’s finance minister who is also running for the chance to replace her and return his Social Democratic Party to the chancellery, headed on Friday to flooded regions in Rhineland-Palatinate, where he pledged swift help from the government and linked the disaster to climate change.
“I am firmly convinced that our task is stopping human-made climate change,” Mr. Scholz told ZDF public television.

They were disabled residents of a care home, the Lebenshilfe Haus, asleep when the waters of the flash flood suddenly rose early Thursday morning. Trapped on the first floor, they drowned before aid could arrive.
As calamitous floods hit Germany, the deaths of 12 people at a care home in Sinzig, a small town between the Rhine and Ahr rivers, have broken hearts all over the country and demonstrated how tragedy could have been avoided had flood warnings been better heeded.
“Every person who dies is a tragedy,” said Tabera Irrle, 23, a train driver who came to Sinzig to help with the cleanup. “But this is a special sadness.”
Neighbors could hear screaming, they said later, but all that emergency workers could do was save the other 24 residents on higher floors some three hours later, bringing them out the windows in small boats. The disabled residents had been under the care of a lone watchman.
Dominik Gasper, 17, was helping his parents and uncle clean out the mud and ruined belongings of his grandparents’ house near the care home. He knew about the 12 dead, he said.
“It was so horrible,” he said. “You can’t really understand such a thing.”
The waters crested in Sinzig at more than 7 meters, about 23 feet, the highest in a century, said Andreas Geron, the mayor. He said emergency workers in fire trucks had tried to warn residents late Wednesday night, but few said they had heard an alarm.
Two other Sinzig residents died in this town of 20,000, and a newly renovated bridge over the Ahr collapsed.
Luis Rufino, 50, a lifelong resident of Sinzig, was angry about what happened. He said some of it could have been prevented.
“Our health system is better than in the U.S., but they are still trying to avoid costs,” he said. “So there was only one guy watching over these poor people, and when the lights went out, they went into a panic, and when the flood came through, they had no chance.”
Ulrich van Bebber, the chairman of Lebenshilfe, which has operated the care home since it was built 27 years ago, told journalists that “we are all horrified, stunned and infinitely sad.”
He said those who survived were being cared for. “We want to keep the Lebenshilfe Haus as a residential facility and, if necessary, rebuild it.”

Usually a national leader faced with floods as severe as those in Germany would be expected to break off whatever she was doing and rush to the crisis area.
But Chancellor Angela Merkel of Germany completed an official visit to Washington that ended Friday, and she was not expected to visit the flood zone until Sunday, long after most other German political leaders had come and gone. (Saturday was also her 67th birthday.)
Ms. Merkel did express from Washington her sympathy to the victims, saying during an appearance with President Biden on Thursday: “My heart goes out to all of those who, in this catastrophe, lost their loved ones or who are still worrying about the fate of people still missing.”
And hours after touching down in Germany on Friday morning, Ms. Merkel took part in a crisis meeting with leaders of the state of Rhineland Palatinate, where many of the hardest-hit communities are. She also spoke by telephone with Armin Laschet, the leader of North Rhine Westphalia, which also suffered major devastation and loss of life.
Mr. Laschet — who, like Ms. Merkel, is a member of the conservative Christian Democratic Union party — is the party’s candidate to succeed her after the country holds elections in September.
So far Ms. Merkel has not faced major criticism for taking several days to see the damage for herself. She has never been one for political theater, and does not need to worry about opinion polls because she is stepping down from politics after the elections.
Germans also seemed to understand the importance of her trip to Washington — probably her last as chancellor — and meetings with Mr. Biden.
Germany is anxious to repair its relationship with the United States, a crucial ally and trading partner, after four tense years of dealing with President Donald J. Trump, who treated Germany like a rival and threatened to impose punitive tariffs on German cars. At a news conference with Mr. Biden on Thursday, Ms. Merkel seemed almost buoyant to be dealing with a new administration.
“We’re not only partners and allies, but we’re very close friends,” she said of Mr. Biden.
Addressing an underlying cause of Western Europe’s worst floods in centuries, the two leaders signed a pact to take “urgent action to address the climate crisis.”
“There is a dramatic increase in such unusual weather phenomena, and we have to contend with this,” Ms. Merkel said while standing alongside Mr. Biden.
Huge cleanup efforts were underway after days of flooding inundated parts of Western Europe this week.

President Frank-Walter Steinmeier of Germany on Saturday visited the city of Erftstadt, where floods had ripped away homes, setting off a landslide that wrought further destruction.
An entire stretch of highway remained submerged there on Saturday as fears mounted that people who had tried to flee this week’s torrential rains could have been trapped in their cars by flash flooding — and may still be found when the waters recede.
Already, at least 43 people are known to have died.
Mr. Steinmeier, who is seeking a second term in office after his current one ends in February, urged Germans to help in any way they could.
“Many people in this region have nothing left but hope,” Mr. Steinmeier said. “And we cannot disappoint these hopes.”
A president’s role in Germany is largely ceremonial, but in times of national tragedy or crisis, the head of state often helps set the tone and serve as a representative of the people.
Mr. Steinmeier was joined by Armin Laschet, governor of North Rhine-Westphalia, home to Erftstadt, and the leading candidate to succeed Chancellor Angela Merkel when Germans vote for a new government in the fall.
Ms. Merkel planned to travel on Sunday to the town of Schuld (not Stuhr as an earlier version of this item said) in Rhineland-Palatinate.

Extreme weather disasters across Europe and North America have highlighted two essential facts of science and history: The world as a whole is neither prepared to slow down climate change, nor live with it.
Some of Europe’s richest countries lay in disarray this weekend, as rivers burst through banks in Germany and Belgium, leaving people shellshocked at the intensity of the destruction.
Days before in the Northwestern United States, hundreds had died of heat. In Canada, wildfire had burned a village off the map. Moscow reeled from record temperatures. And the northern Rocky Mountains were bracing for another heat wave.
The events have ravaged some of the world’s wealthiest nations, whose affluence has been enabled by more than a century of burning coal, oil and gas — activities that pumped the greenhouse gases into the atmosphere that are warming the world.
“I say this as a German: The idea that you could possibly die from weather is completely alien,” said Friederike Otto, a physicist at Oxford University who studies the links between extreme weather and climate change. “There’s not even a realization that adaptation is something we have to do right now. We have to save peoples’ lives.”
Disasters magnified by global warming have left a trail of death and loss across much of the developing world, wiping out crops in Bangladesh, leveling villages in Honduras and threatening the very existence of small island nations.
A big question is whether the disasters in the developed world will have a bearing on what the world’s most influential countries and companies will do to reduce their own emissions of planet-warming gases.
“This tragic event is a reminder that, in the climate emergency, no one is safe,” Mohamed Nasheed, the former president of the Maldives, said in a statement about the flooding.

The floods devastating Europe have killed scores of people, leaving at least 1,300 missing, uprooting families, causing immense financial damage and reducing homes and cars to the state of floating bath toys. But it is not the first time the continent has been buffeted by a deluge.
Here are some of the other major lethal floods and flooding caused by storms in recent years.

In a matter of months in 2014, at least 5,000 houses in Britain were damaged in what was then seen as one of the rainiest seasons in nearly 250 years. While some blamed the flooding on the austerity measures of David Cameron, the prime minister at the time, others pointed to climate change.
In May of that year, the heaviest rains and floods in 120 years hit Bosnia and Serbia, killing at least 33 people, forcing thousands out of their homes, and cutting off power in 100,000 households in Serbia, as several months’ worth of rainfall fell in a matter of days.

Germany is no stranger to flooding.
In Bitterfeld, in eastern Germany, about 10,000 people were asked to leave their homes in June 2013 after a levee on the Mulde River burst, amid some of the worst flooding that some German regions had seen in centuries. More than 600 residents of Dresden were brought to safety as electricity and water services to the city’s affected center were cut off.
Chancellor Angela Merkel, now tested by the current flooding, showed her mettle at the time, touring three of the hardest-hit areas to wade through ankle-deep floodwaters and visit victims of the flood.

The storm was called Kyrill by German meteorologists, and it spurred unrelenting rain in Britain, Ireland, France, Belgium and the Netherlands.
The howling gale churned through the British Isles and Northern Europe, uprooting trees, shattering windows, flooding beaches and forcing the cancellation of hundreds of flights at airports from London to Frankfurt.
According to the European Environment Agency, Kyrill killed 46 people and resulted in overall losses worth 8 billion euros. At the time, it was one of the most damaging extreme weather episodes ever recorded in Europe.
The name Kyrill stemmed from a German practice of naming weather systems. Anyone may name one, for a fee, and three siblings had paid to name the system as a 65th birthday gift for their father, not realizing it would grow into a fierce storm.

Such was the deluge in Central and Southern Europe in 2005 that in the Alps, military helicopters were deployed to ferry in supplies, evacuate stranded tourists and even stranded cows in mountain pastures threatened by rising water.
The floods left dozens dead. In Romania, which was badly affected by the flooding, victims were drowned as torrents of water rushed into their homes. Austria, Bulgaria, Germany and Switzerland were also buffeted by the flooding.
The scenes of devastation were visceral and shocking. The Aare River broke through the windows of a children’s clothes shop in Bern, leaving baby strollers and toys floating in muddy water. Much of the historic old city of Lucerne remained underwater.
Meanwhile, in southern Poland, rivers broke their banks and at least seven bridges collapsed.

In 2002, some of the worst rains since 1890 pelted the Czech Republic, putting part of the historic center of Prague underwater and resulting in 50,000 residents being ordered to evacuate, as rivers swelled by near constant rain.
The death toll from the floods, which ravaged East and Central Europe, including Germany and Austria, and southern Russia, was more than 110. The flooding caused billions of dollars’ worth of damage.
The management of the crisis by Germany’s chancellor, Gerhard Schröder, helped propel him to re-election.
In Austria, the Salzach River burst its banks south of Salzburg and threatened to inundate the city at the height of its famous summer festival, forcing the authorities to close most bridges and major roads.

Was the flooding caused by climate change?
Tying a single weather event to climate change requires extensive attribution analysis, and that takes time, but scientists know one thing for sure: Warmer air holds more moisture, and that makes it more likely that any given storm will produce more precipitation.
For every 1 Celsius degree of warming, air can hold 7 percent more moisture.
On average, the world has warmed by a little more than 1 degree Celsius (about 2 degrees Fahrenheit) since the 19th century, when societies began pumping huge amounts of greenhouse gases into the atmosphere.
“Any storm that comes along now has more moisture to work with,” said Jennifer Francis, a senior scientist with the Woodwell Climate Research Center in Massachusetts. “That’s the straightforward connection to the increased frequency of heavy downpours.”
And although it is still a subject of debate, some scientists say climate change might be causing storms to linger longer.
Some studies suggest that rapid warming in the Arctic is affecting the jet stream. One consequence of that, said Hayley Fowler, a professor of climate change impacts at Newcastle University in England, is that the river of wind is weakening and slowing down at certain times during the year, including summer. That, in turn, affects weather systems farther south.
“That means the storms have to move more slowly,” Dr. Fowler said. The storm that caused the flooding was practically stationary, she noted.
The combination of more moisture and a stalled storm system means that a lot of rain can fall over a given area.
Geert Jan van Oldenborgh, one of the primary scientists with World Weather Attribution, a group that quickly analyzes extreme weather events to see whether they were made more likely by climate change, said the group was discussing whether to study the German floods.
Beyond the speed of a weather system and its moisture content, there are many factors that affect flooding that can make an analysis difficult. Local topography has to be taken into account, as that can affect how much runoff gets into which rivers.
Human impacts can complicate the analysis even further. Development near rivers can make runoff worse by reducing the amount of open land that can absorb rain. And infrastructure built to cope with heavy runoff and rising rivers may be under-designed and inadequate.

While some development in cities and elsewhere can make flooding worse, other projects can reduce flooding. That appears to have been the case in the Netherlands, which was not as severely affected as neighboring Germany by this week’s storm.
After several major floods on the Meuse River in the 1990s, the Dutch government began a program called Room for the River to reduce flooding, said Nathalie Asselman, who advises the government and other clients on flood risk.
The work involved lowering and widening river beds, lowering flood plains and excavating side channels.
“The aim of these measures is to lower flood levels,” she said.
Taming water in the Netherlands, a waterlogged country, has been a matter of survival for centuries, and the imperative to keep levels under control is inextricably bound up with Dutch identity. Much of the country sits below sea level and is gradually sinking. Climate change has also exacerbated the twin threats of storms and rising tides.
While a dike near the Meuse in southern Netherlands suffered a breach that caused some flooding until it was repaired on Friday, the measures appear to have worked.
The breach, in the dike along the Juliana Canal in the southern Netherlands, was closed by the Dutch military by dumping hundreds of sandbags into the growing hole. Hours before, thousands had been told to evacuate after the dike was breached along the canal, a 22-mile waterway that regulates the Meuse River.
The river’s water level is at heights not witnessed since 1911, the Dutch national broadcaster NOS reported. Yet water levels on the Meuse were about a foot lower than would have been the case without the flood-reduction measures, Ms. Asselman said. That meant that smaller tributaries backed up less where they met the Meuse, producing less flooding.
“If we wouldn’t have implemented these measures, then the situation would have been worse,” she said. “Both on the main river and the tributaries.”

An increasingly hot, dry and deadly summer has gripped much of the Western United States, with heat claiming lives in the Pacific Northwest and Canada in record numbers, and a deepening drought threatening water supplies — all of which is setting the stage for another potentially catastrophic fire season in California and neighboring states.
A fourth major heat wave was forecast to roast parts of the region again this weekend. It comes two weeks after a record-shattering spate of high temperatures — which scientists said would been virtually impossible without climate change — killed hundreds of people in the United States and Canada.
A week ago, Death Valley hit a 130-degree high, matching a reading from last year that may be the highest reliably recorded temperature on earth. Also this past weekend, Las Vegas tied its record high, 117 degrees, and Grand Junction, Colo., topped its previous record, hitting 107 degrees.
At least 67 weather stations from Washington State through New Mexico have recorded their hottest temperatures ever this summer, the National Weather Service said this week. Those records stretched back at least 75 years.
The heat helped drive the rapid growth of a wildfire in southern Oregon, known as the Bootleg Fire, that has burned more than 240,000 acres — about a third the size of Rhode Island, America’s smallest state. The fire, the largest of dozens across the West, has destroyed about two dozen homes, threatens 1,900 more and has set off a wave of evacuations.
The fire also burned across a power line corridor that serves as a major contributor to the electrical grid in California, where officials have issued warnings this week asking residents to conserve power by turning up their thermostats and turning off appliances, or risk rolling blackouts.
One part of the West saw some relief from the crushing heat this week, as monsoon rains fell on the Southwest, including New Mexico and Arizona. But the result was yet another disaster: flash flooding that left some city streets in Arizona awash in muddy water and propelled a torrent of water through part of the Grand Canyon, washing away a camp where about 30 people on a rafting trip were spending the night, killing one.
As the Earth warms from climate change, heat waves are becoming hotter and more frequent. “And as bad as it might seem today,” Jonathan Overpeck, a climate scientist at the University of Michigan, recently told The New York Times, “this is about as good as it’s going to get if we don’t get global warming under control.”
devastation from the floods came from all around Western Europe as the death toll passed 125 on Friday, with another 1,300 people still missing. Roads buckled and washed away. Cars piled atop one another. Houses were inundated to the roof tiles. Frightened residents were being evacuated in the shovels of earth movers.
But nowhere was affected more than Germany, where hundreds were still unaccounted for and the death toll had reached 106 and was expected to rise as rescue workers combed through the debris. At least 20 were reported dead in Belgium.
A European weather agency had issued an “extreme” flood warning after detailed models showed storms that threatened to send rivers surging to levels that a German meteorologist said on Friday had not been seen in 500 or even 1,000 years.
German officials said Friday their warning system, which includes a network of sensors that measure river levels in real time, functioned as it was supposed to. The problem, they said, was an amount of rain they had never seen before — falling so rapidly that it engorged even small streams and rivers not normally considered threats.
Extreme downpours like the ones that occurred in Germany are among the most visible and damaging signs that the climate is changing as a result of warming caused by greenhouse gas emissions. Studies have found that they are now occurring more frequently, and scientists point to a simple reason: A warmer atmosphere can hold more moisture, which creates extreme rainfall.
In Central Europe rescue efforts were hampered, with electricity and communications networks down, roads and bridges washed out, and drinking water scarce. The worst hit were thinly populated, rural areas.
In the city of Schleitheim, Switzerland, where a river burst its banks, residents recorded videos of cars being washed through the streets in a swirling flood of muddy water and debris.
Germans struggled even to grasp the scale of the calamity in their country. Chancellor Angela Merkel expressed her shock and solidarity from Washington, where she was visiting the White House. Politicians of all stripes called for a truce in the German election campaign. The focus was on how to deal with a disaster that was growing by the hour, with thousands left homeless, in addition to the missing.
In Belgium,the Meuse river overflowed its banks, flooding villages and the center of Liège, leaving thousands without power. The official death toll stands at 20 dead and 20 missing, the authorities said.
“We are still waiting for the final assessment, but these floods could have been the most disastrous that our country has ever known,” Alexander De Croo, Belgium’s prime minister said on Friday.
Relatives of those missing grappled with the fear of the unknown. The authorities in the Ahrweiler district of Rhineland-Palatinate said late Thursday that 1,300 people remained unaccounted for in their region, where the Ahr river swelled to an angry torrent late Wednesday, ripping through the towns and villages that hugged its banks.

One of the places in Germany hardest hit by the flooding was tiny Schuld, where the destruction arrived with remarkable speed in the once-tidy village. After the river swelled, vehicles bobbed like bath toys, six houses collapsed and half of those that remained standing had gaping holes torn by floating debris.
“It went so fast. You tried to do something, and it was already too late,” a resident of Schuld told Germany’s ARD public television.
At least 50 people were confirmed dead in the Ahrweiler district, where torrents of water rushed through towns and villages, washing away cars, homes and businesses.
In Sinzig, a town in the district, efforts to evacuate a care home for people with severe disabilities came just moments before the gushing waters swept through the lower levels, killing 12 of the residents.

BERLIN — Days before roiling waters tore through western Germany, a European weather agency issued an “extreme” flood warning after detailed models showed storms that threatened to send rivers surging to levels that a German meteorologist said on Friday had not been seen in 500 or even 1,000 years.
By Friday those predictions proved devastatingly accurate, with at least 125 people dead and 1,300 unaccounted for, as helicopter rescue crews plucked marooned residents from villages inundated sometimes within minutes, raising questions about lapses in Germany’s elaborate flood warning system.
Numerous areas, victims and officials said, were caught unprepared when normally placid brooks and streams turned into torrents that swept away cars, houses and bridges and everything else in their paths.
“It went so fast. You tried to do something, and it was already too late,” a resident of Schuld told Germany’s ARD public television, after the Ahr River swelled its banks, ripping apart tidy wood-framed houses and sending vehicles bobbing like bath toys.
Extreme downpours like the ones that occurred in Germany are one of the most visible signs that the climate is changing as a result of warming caused by greenhouse gas emissions. Studies have shown a warmer atmosphere can hold more moisture, generating more, and more powerful, rainfall.
The floods that cut a wide path of destruction this week through Germany, Belgium, Switzerland and the Netherlands were bigger than any on record, according to meteorologists and German officials.
German officials said Friday their warning system, which includes a network of sensors that measure river levels in real time, functioned as it was supposed to. The problem, they said, was an amount of rain they had never seen before — falling so rapidly that it engorged even small streams and rivers not normally considered threats.
To describe the events of recent days as a 100-year flood would be an understatement, said Uwe Kirsche, a spokesman for the German Weather Service.
“With these small rivers, they have never experienced anything like that,” Mr. Kirsche said. “Nobody could prepare because no one expected something like this.”
On Tuesday, Felix Dietsch, a meteorologist for the German Weather Service, went on YouTube to warn that some areas of southwest Germany could receive previously unimaginable volumes of rain.
The weather service, a government agency, assigned its most extreme storm warning, code purple, to the Eifel and Mosel regions, one of numerous government warnings issued on Twitter and other media earlier this week and transmitted to state and local officials.
But the waters rose so swiftly that some communities’ response plans were insufficient while others were caught off guard entirely.
Medard Roth, the mayor of Kordel, in the hard-hit state of Rhineland-Palatinate, said that he activated his town’s emergency flood response once Kyll River approached dangerous water levels. But the waters rose too rapidly to be held back by the usual measures.
“By 6 p.m., everything was already under water,” Mr. Roth told Bild, a German newspaper. “Nobody could have predicted that.”
Ursula Heinen-Esser, the environment minister for the state of North Rhine-Westphalia, said on Friday that floodwaters had reached “levels never before recorded.”
The German flood warning system leaves it up to local officials to decide what action to take, on the theory that they are best informed about local terrain and what people or property lies in the path of an overflowing river.
In the Ahrweiler district of neighboring Rhineland-Palatinate, regional officials issued their first warning to residents living near the banks of the river as it approached its record level of 3 meters, or nearly 10 feet. Three hours later, a state of emergency was declared.
By that time, many people had fled to the upper levels of their homes, and those who could not move fast enough died, including 12 handicapped people in an assisted living home in Sinzig.
“The warnings arrived,” Mr. Kirsche of the German Weather Service said. “But the question is why didn’t evacuations take place sooner? That’s something we have to think about.”

MÜSCH, Germany — The bridge that spans the River Ahr washed away last night at around 10:00, said Michael Stoffels, 32, whose own house got flooded by about 12 feet of water.
Müsch, a village of 220 people at the junction of the Ahr and Trierbach rivers, was clobbered by the flash floods that have inundated this part of Germany. Only one person has died, but Müsch on Friday evening was without electricity, running water or cellphone coverage.
Residents and their friends were trying to clean up their battered homes, cracked streets and ruined cars. Local firefighters, like Nils Rademacher, 21, were managing the traffic of bulldozers, small trucks and backhoes, while instructing drivers that roads farther into the river valley were blocked with trees or made impassable by fallen bridges.
“A lot of good cars crashed or got crushed,’’ said Maria Vazquez, who works in a nearby auto repair shop. “I work with cars, so that’s sad, but I just hope that all the people are OK.”
The water rose to flood the village in less than two hours on Wednesday, and came halfway up the houses, Ms. Vazquez said.
The riverbanks were scenes of devastation, with crushed cars and thick tree stumps, while many of the cobbled streets were covered with mud and debris. Truckloads of broken furniture, tree branches and chunks of stone were being driven slowly over downed power lines.
The yellow road sign that tells drivers that they have entered Müsch was pulled out of the ground, laying bent and nearly adrift in the Trierbach River.
Mr. Stoffels said that he had no warning from the government, but that he rushed home from the retail store he manages nearby when a neighbor called. He was lucky, he said, since he has storage on the ground level and his living area is above that. The children’s playground next to his home, along the Ahr, was shattered, as was the main village electrical station, even before the bridge washed away.
He and his brother, who traveled 100 miles to help, and his friends, all wearing boots and muddy clothes, were trying to clean up as best they could. It helped, he said, that Müsch, in the Ahrweiler District of Rhineland-Palatinate close to the border with North Rhine-Westphalia, is farming country.
“Nearly everyone has a small tractor or a bulldozer of some kind,’’ he said. And it was true — the local firefighters were there, but there was little government presence, residents said. On Thursday, Mr. Stoffels said, “a couple of soldiers came for a time and a policeman looked around.”
Not far away, larger villages and towns were devastated, and more than 1,000 people are reported missing by the authorities.
Roger Lewentz, Rhineland-Palatinate’s interior minister, was unable to give an exact number of missing in his state.
“We do not yet know for sure whether some of them may be on vacation or simply unavailable. After all, the power and telephone connections are down in many affected locations,” he told Der Spiegel.
“There haven’t been floods like this here in 100 years,’’ said Sebastian Stich, 28, an office worker from nearby Barweiler who came to help his neighbors. “The bridges, the power, it’s all gone.’’

The floods devastating Europe have killed scores of people, leaving at least 1,300 missing, uprooting families, causing massive financial damage and reducing homes and cars to the state of floating bath toys.But it is not the first time the continent has been buffeted by a deluge. Here are some of the other major lethal floods and flooding caused by storms in recent years:

While some blamed the flooding on the austerity measures of David Cameron, the prime minister at the time, others pointed to climate change. In May of that same year, the heaviest rains and floods in 120 years hit Bosnia and Serbia, killing at least 33 people, forcing thousands out of their homes, and cutting off power in 100,000 households in Serbia, as several months’ worth of rainfall fell in a matter of days.

Germany is no stranger to flooding. In Bitterfeld, in eastern Germany, some 10,000 people were asked to leave their homes in June 2013 after a levee on the Mulde River burst, amid some of the worst flooding that some German regions had seen in centuries. More than 600 residents of Dresden were brought to safety as electricity and water services to the city’s affected center were cut off. Chancellor Angela Merkel, now tested by the current flooding, showed her mettle at the time, touring three of the hardest hit areas to wade through ankle-deep floodwaters and visit victims of the flood.

The storm was called Kyrill by German meteorologists, and it spurred unrelenting rain in Britain, Ireland, France, Belgium and the Netherlands. The howling gale churned through the British Isles and Northern Europe, uprooting trees, shattering windows, flooding beaches and forcing the cancellation of hundreds of flights at airports from London to Frankfurt. According to the European Environment Agency, Kyrill killed 46 people and resulted in overall losses worth 8 billion euros. At the time, it was one of the most damaging extreme weather episodes ever recorded in Europe. The name Kyrill stemmed from a German practice of naming weather systems. Anyone may name one, for a fee, and three siblings had paid to name the system as a 65th birthday gift for their father, not realizing it would grow into a fierce storm.

Such was the deluge in Central and Southern Europe in 2005 that in the Alps, military helicopters were deployed to ferry in supplies, evacuate stranded tourists and even stranded cows in mountain pastures threatened by rising water. The floods left dozens dead. In Romania, which was badly affected by the flooding, victims were drowned as torrents of water rushed into their homes. Austria, Bulgaria, Germany and Switzerland were also buffeted by the flooding. The scenes of devastation were visceral and shocking. The Aare River broke through the windows of a children’s clothes shop in Bern, leaving baby strollers and toys floating in muddy water. Much of the historic old city of Lucerne remained underwater. Meanwhile, in southern Poland, rivers broke their banks and at least seven bridges collapsed.

In 2002, some of the worst rains since 1890 pelted the Czech Republic, putting part of the historic center of Prague underwater and resulting in 50,000 residents being ordered to evacuate, as rivers swelled by near constant rain. The death toll from the floods, which ravaged East and Central Europe, including Germany and Austria, and southern Russia, was more than 110. The flooding caused billions of dollars worth of damage. The floods helped propel Germany’s chancellor, Gerhard Schröder, to re-election because of his management of the crisis. In Austria, the Salzach River burst its banks south of Salzburg and threatened to inundate the city at the height of its famous summer festival, forcing the authorities to close most bridges and major roads. Floodwaters rose in Hungary and Germany, and in northern Austria the authorities halted river traffic on parts of the Danube.

Was the flooding caused by climate change?
Tying a single weather event to climate change requires extensive attribution analysis, and that takes time, but scientists know one thing for sure: Warmer air holds more moisture, and that makes it more likely that any given storm will produce more precipitation.
For every 1 Celsius degree of warming, in fact, air can hold 7 percent more moisture.
On average, the world has warmed by a little more than 1 degree Celsius (about 2 degrees Fahrenheit) since the 19th century, when societies began pumping huge amounts of greenhouse gases into the atmosphere.
“Any storm that comes along now has more moisture to work with,” said Jennifer Francis, a senior scientist with the Woodwell Climate Research Center in Massachusetts. “That’s the straightforward connection to the increased frequency of heavy downpours.”
And, although it is still a subject of debate, some scientists say climate change might be causing storms to linger longer.
Some studies suggest that rapid warming in the Arctic is affecting the jet stream. One consequence of that, said Hayley Fowler, a professor of climate change impacts at Newcastle University in England, is that the river of wind is weakening and slowing down at certain times during the year, including summer. And that, in turn, affects weather systems farther south.
“That means the storms have to move more slowly,” Dr. Fowler said. The storm that caused the flooding was practically stationary, she noted.
The combination of more moisture and a stalled storm system means a lot of rain can fall over a given area.
Geert Jan van Oldenborgh, one of the primary scientists with World Weather Attribution, a group that quickly analyzes specific extreme weather events to see whether they were made more likely, or not, by climate change, said the group was discussing whether they would study the German floods.
Beyond the speed of a weather system and its moisture content, there are many factors that affect flooding that can make an analysis difficult. Local topography has to be taken into account, as that can affect how much runoff gets into which rivers.
Human impacts can complicate the analysis even further. Development near rivers, for instance, can make runoff worse by reducing the amount of open land that can absorb rain. Infrastructure built to cope with heavy runoff and rising rivers may be under-designed and inadequate.

A breach in the dike along the Juliana Canalin the southern Netherlands on Friday was closed by the Dutch military by dumping hundreds of sandbags into the growing hole. Hours before, thousands had been told to evacuate after the dike was breached along thecanal, a 22-mile waterway that regulates the Meuse River.
The river’s water level is at heights not witnessed since 1911, the Dutch national broadcaster NOS reported.
That is no small thing is a water-logged country where taming water has been a matter of survival for centuries and the imperative to keep levels under control is inextricably bound up with Dutch identity.Much of the country sits below sea level and is gradually sinking. Climate change has also exacerbated the twin threats of storms and rising tides.
Residents of the villages of Brommelen, Bunde, Geulle and Voulwames were ordered to evacuate immediately, after initially being told to move to higher floors in their homes. About 10,000 people live in the area.
The local authorities said there was “a large hole” in the dike, prompting fears that the entire area would be flooded. While parts of the area were flooded, a disaster was averted after the breach was closed. NOS said the dike was still unstable and continued to be monitored.
Upriver, near the city of Venlo, evacuations were ordered for whole neighborhoods and surrounding villages, in total10,700 people and 7,100 houses, the municipality said in a tweet. People have until 6 p.m. local time to leave their homes.
Record water levels are moving through the Meuse River, prompting evacuations andfresh inspections of dikes along the river that empties into the North Sea. The river is a key waterway for European shipping connections.
Following flooding in recent decades, the Dutch authorities have designated special areas that can be flooded with excess water when critical levels are reached.
The Netherlands has so far been spared much of the death and destruction that this week’s flooding has caused in Germany and Belgium. But in Valkenburg, a city in the south of the Netherlands with about 16,000 residents, damage was severe. Hundreds of houses were without power, and the center of the city was flooded.
“The damage is incalculable,” Mayor Daan Prevoo of Valkenburg told the Algemeen Dagblad newspaper. He predicted that repairs would take weeks.

In Liège, Belgium’s third-largest city, much of the early panic eased on Friday as residents said the waters of the Meuse river seemed to recede, at least a bit.
Fears that a major dam might break led the mayor to call for parts of the city to be evacuated late Thursday. But on Friday, people were allowed back, though they were told to stay away from the river, which was still lapping over its banks.
“The situation is now under control, and people can return to their homes,” Laurence Comminette, the spokeswoman for the mayor, said in an interview. “Of course not everyone can go back, because many homes have been destroyed. But there is no longer an imminent danger of more flooding.”
Georges Lousberg, 78, said he thought the crisis was largely over in the city. “It did not rain much today, and the weather is supposed to be better the rest of the week.”
He said there had been times when the Meuse was even higher, especially before walls were built along its banks. “The worst flooding was in 1926,” he said.
Prasanta Char, 34, a postdoctoral student in physics at the University of Liège, said he had been anxious about rain overnight after the mayor’s evacuation call.
He had gone looking to buy water, but had a hard time because so many stores were closed. He finally found a small convenience store in the shuttered city.
“It’s much worse in Germany, and a lot of the roads are shut and the trains are stopped,” he said, “I’m still a bit anxious about rain, but today it seems better.”

Forecasts predicting improved weather for Western Europe over the weekend offered some hope amid the deluge, potentially aiding search-and-rescue efforts in areas devastated by floods.
The heavy rain in Germany in the Ahrweiler district of Rhineland-Palatinate was forecast to let up later Friday and over the weekend, after flooding left 1,300 people unaccounted for in the region. Emergency workers put sandbags in place to stem the rising waters in the region’s remote villages, like Schuld, where heavy flows of water washed away six homes and left more close to collapse.
On Saturday and Sunday, there is about a 20 percent chance of rain in that area, and temperatures are expected to rise above 70 degrees Fahrenheitwith partial sunshine later in the day, according to Weather.com. Conditions are likewise expected to improve in the state of North Rhine-Westphalia, also in western Germany, where at least 43 people have died in the flooding.
Andreas Friedrich, a meteorologist for Germany’s national weather service, said that dry, sunny weather was likely over the next few days in the western states hit by floods. The weather service has issued a warning about possible floods in the touristy area of southeastern Germany, north of the Alps, over the weekend, but conditions are not expected to be as bad as they were in the western part of the country, he said.
In Belgium, the weather is also expected to clear up over the weekend. The Royal Meteorological Institute of Belgium forecast only light rain in the hilly Ardennes region, which experienced heavy flooding over the past few days. In Liège, which was also hard hit, there was a 3 percent chance of precipitation on Saturday, according to the AccuWeather forecasting service.
Alex Dewalque, a spokesman for the meteorological institute, said water levels in the worst-hit parts of Belgium were already falling, making it easier for emergency workers to rescue stranded people and search for casualties. He said the coming days would be much drier and with warmer temperatures, and that there were no flood warnings.
More rain was expected in Switzerland’s northern Alps on Friday, however, and officials warned of more potential flooding in parts of the country. Lake Lucerne reached critical levels, forcing the closing of some bridges and roadways.
Sarah Schöpfer,a meteorologist at Switzerland’s Federal Office of Meteorology and Climatology MeteoSwiss, said she expected rainfall over the affected areas of Switzerland to lighten.
“We expect that tonight the precipitation activity weakens further and tomorrow it mainly affects the eastern Swiss Alps (mainly regions that did not get the highest amounts of rain during the last few days),” she said in an email. “So apart from the last showers today and tomorrow, the following days will be dry.”
In the story of how the modern world was constructed, Toyota stands out as the mastermind of a monumental advance in industrial efficiency. The Japanese automaker pioneered so-called Just In Time manufacturing, in which parts are delivered to factories right as they are required, minimizing the need to stockpile them.
Over the last half-century, this approach has captivated global business in industries far beyond autos. From fashion to food processing to pharmaceuticals, companies have embraced Just In Time to stay nimble, allowing them to adapt to changing market demands, while cutting costs.
But the tumultuous events of the past year have challenged the merits of paring inventories, while reinvigorating concerns that some industries have gone too far, leaving them vulnerable to disruption. As the pandemic has hampered factory operations and sown chaos in global shipping, many economies around the world have been bedeviled by shortages of a vast range of goods — from electronics to lumber to clothing.
In a time of extraordinary upheaval in the global economy, Just In Time is running late.
“It’s sort of like supply chain run amok,” said Willy C. Shih, an international trade expert at Harvard Business School. “In a race to get to the lowest cost, I have concentrated my risk. We are at the logical conclusion of all that.”
shortage of computer chips — vital car components produced mostly in Asia. Without enough chips on hand, auto factories from India to the United States to Brazil have been forced to halt assembly lines.
But the breadth and persistence of the shortages reveal the extent to which the Just In Time idea has come to dominate commercial life. This helps explain why Nike and other apparel brands struggle to stock retail outlets with their wares. It’s one of the reasons construction companies are having trouble purchasing paints and sealants. It was a principal contributor to the tragic shortages of personal protective equipment early in the pandemic, which left frontline medical workers without adequate gear.

“People adopted that kind of lean mentality, and then they applied it to supply chains with the assumption that they would have low-cost and reliable shipping,” said Mr. Shih, the Harvard Business School trade expert. “Then, you have some shocks to the system.”
An Idea That Went ‘Way Too Far’
presentation for the pharmaceutical industry. It promised savings of up to 50 percent on warehousing if clients embraced its “lean and mean” approach to supply chains.
Such claims have panned out. Still, one of the authors of that presentation, Knut Alicke, a McKinsey partner based in Germany, now says the corporate world exceeded prudence.
“We went way too far,” Mr. Alicke said in an interview. “The way that inventory is evaluated will change after the crisis.”
Many companies acted as if manufacturing and shipping were devoid of mishaps, Mr. Alicke added, while failing to account for trouble in their business plans.
“There’s no kind of disruption risk term in there,” he said.
Experts say that omission represents a logical response from management to the incentives at play. Investors reward companies that produce growth in their return on assets. Limiting goods in warehouses improves that ratio.
study. These savings helped finance another shareholder-enriching trend — the growth of share buybacks.
In the decade leading up to the pandemic, American companies spent more than $6 trillion to buy their own shares, roughly tripling their purchases, according to a study by the Bank for International Settlements. Companies in Japan, Britain, France, Canada and China increased their buybacks fourfold, though their purchases were a fraction of their American counterparts.
Repurchasing stock reduces the number of shares in circulation, lifting their value. But the benefits for investors and executives, whose pay packages include hefty allocations of stock, have come at the expense of whatever the company might have otherwise done with its money — investing to expand capacity, or stockpiling parts.
These costs became conspicuous during the first wave of the pandemic, when major economies including the United States discovered that they lacked capacity to quickly make ventilators.
“When you need a ventilator, you need a ventilator,” Mr. Sodhi said. “You can’t say, ‘Well, my stock price is high.’”
When the pandemic began, car manufacturers slashed orders for chips on the expectation that demand for cars would plunge. By the time they realized that demand was reviving, it was too late: Ramping up production of computer chips requires months.

The automaker least affected by the shortage is Toyota. From the inception of Just In Time, Toyota relied on suppliers clustered close to its base in Japan, making the company less susceptible to events far away.
‘It All Cascades’
In Conshohocken, Pa., Mr. Romano is literally waiting for his ship to come in.
He is vice president of sales at Van Horn, Metz & Company, which buys chemicals from suppliers around the world and sells them to factories that make paint, ink and other industrial products.
In normal times, the company is behind in filling perhaps 1 percent of its customers’ orders. On a recent morning, it could not complete a tenth of its orders because it was waiting for supplies to arrive.
The company could not secure enough of a specialized resin that it sells to manufacturers that make construction materials. The American supplier of the resin was itself lacking one element that it purchases from a petrochemical plant in China.
One of Mr. Romano’s regular customers, a paint manufacturer, was holding off on ordering chemicals because it could not locate enough of the metal cans it uses to ship its finished product.
“It all cascades,” Mr. Romano said. “It’s just a mess.”
No pandemic was required to reveal the risks of overreliance on Just In Time combined with global supply chains. Experts have warned about the consequences for decades.
In 1999, an earthquake shook Taiwan, shutting down computer chip manufacturing. The earthquake and tsunami that shattered Japan in 2011 shut down factories and impeded shipping, generating shortages of auto parts and computer chips. Floods in Thailand the same year decimated production of computer hard drives.
Each disaster prompted talk that companies needed to bolster their inventories and diversify their suppliers.
Each time, multinational companies carried on.
The same consultants who promoted the virtues of lean inventories now evangelize about supply chain resilience — the buzzword of the moment.
Simply expanding warehouses may not provide the fix, said Richard Lebovitz, president of LeanDNA, a supply chain consultant based in Austin, Texas. Product lines are increasingly customized.
“The ability to predict what inventory you should keep is harder and harder,” he said.
Ultimately, business is likely to further its embrace of lean for the simple reason that it has yielded profits.
“The real question is, ‘Are we going to stop chasing low cost as the sole criteria for business judgment?’” said Mr. Shih, from Harvard Business School. “I’m skeptical of that. Consumers won’t pay for resilience when they are not in crisis.”
Fox News once devoted its 7 p.m. and 11 p.m. time slots to relatively straightforward newscasts. Now those hours are filled by opinion shows led by hosts who denounce Democrats and defend the worldview of former President Donald J. Trump.
For seven years, Juan Williams was the lone liberal voice on “The Five,” the network’s popular afternoon chat show. On Wednesday, he announced that he was leaving the program, after months of harsh on-air blowback from his conservative co-hosts. Many Fox News viewers cheered his exit on social media.
Donna Brazile, the former Democratic Party chairwoman, was hired by Fox News with great fanfare in 2019 as a dissenting voice for its political coverage. She criticized Mr. Trump and spoke passionately about the Black Lives Matter movement, which other hosts on the network often demonized. Ms. Brazile has now left Fox News; last week, she quietly started a new job at ABC.
Onscreen and off, in ways subtle and overt, Fox News has adapted to the post-Trump era by moving in a single direction: Trumpward.
amounted to an existential moment for a cable channel that is home to Trump cheerleaders like Sean Hannity and Laura Ingraham: the 2020 election.
Fox News’s ratings fell sharply after the network made an early call on election night that Joseph R. Biden Jr., the Democratic presidential nominee, would carry Arizona and later declared him the winner, even as Mr. Trump advanced lies about fraud. With viewers in revolt, the network moved out dissenting voices and put a new emphasis on hard-line right-wing commentary.
the network fired its veteran politics editor, Chris Stirewalt, who had been an onscreen face of the early call in Arizona for Mr. Biden. This month, it brought on a new editor in the Washington bureau: Kerri Kupec, a former spokeswoman for Mr. Trump’s attorney general William P. Barr. She had no journalistic experience.
opinion shows at 7 and 11 — with segments that lament “cancel culture” and attack Mr. Biden — are attracting bigger audiences than the newscasts they replaced. And the niche right-wing network Newsmax has failed to sustain its postelection audience gains.
In some ways, the Murdochs are making a rational business decision by following the conservatives who have made up the heart of the Fox News audience; recent surveys show that more than three-quarters of Republicans want Mr. Trump to run in 2024.
But under Roger Ailes, the network’s founder, who shaped its look and feel, Fox News elevated liberal foils like Alan Colmes, a Democrat who shared equal billing in prime time with Mr. Hannity until the end of 2008, and moderates like Mr. Williams.

“Roger’s view was you had to have some unpredictability and you had to challenge the audience; you couldn’t just be reading Republican talking points every night,” said Susan R. Estrich, a Democratic lawyer and former commentator on Fox News who negotiated Mr. Ailes’s exit from the network amid his sexual misconduct scandal.

Ms. Estrich recalled that Mr. Ailes had defended Megyn Kelly, the former Fox News host, when Mr. Trump, then a presidential candidate, attacked her in misogynist terms. Now, she said, “instead of trying to broaden their audience, Fox News is narrowing it and digging in.”

Ms. Brazile said she had left Fox News of her own accord.
“Fox never censored my views in any way,” she wrote in an email. “Everyone treated me courteously as a colleague.” Ms. Brazile added: “I believe it’s important for all media to expose their audiences to both progressive and conservative viewpoints. With the election and President Biden’s first 100 days behind us, I’ve accomplished what I wanted at Fox News.”
an outcry from the Anti-Defamation League.
A pro-Trump drift at Fox News is not new: George Will, a traditional conservative who opposed Mr. Trump’s candidacy, lost his contributor contract in 2017. Shepard Smith, a news anchor who was tough on Mr. Trump, left in 2019.
Some Fox News journalists, though, say privately that they are increasingly concerned with the network’s direction. Kristin Fisher, one of the network’s rising stars in Washington and a White House correspondent, left Fox News last month despite the network’s effort to keep her. She had faced criticism from viewers in November after a segment in which she aggressively debunked lies about election fraud advanced by Mr. Trump’s lawyers.
The longtime Washington bureau chief, Bill Sammon, resigned in January after internal criticism over his handling of election coverage, around the time that Mr. Stirewalt was fired. (Mr. Stirewalt was let go along with roughly 20 digital journalists at Fox News, which the network attributed to a realignment of “business and reporting structure to meet the demands of this new era.”)
Mr. Sammon has effectively been replaced by Doug Rohrbeck, a producer with extensive news experience on Bret Baier’s newscast and Chris Wallace’s Sunday show. Still, some Fox journalists were surprised when the network hired Ms. Kupec, the former Barr spokeswoman, to work under Mr. Rohrbeck. (In 2019, CNN hired Sarah Isgur, the spokeswoman for former Attorney General Jeff Sessions, as a political editor. After protests from staff, she was shifted to an on-air role and later left the network.)

Despite continuing criticism from liberals, Fox News remains a financial juggernaut for the Murdoch empire; it is expected to earn record advertising revenues this year, the network said.
Even as its programming decisions seem aimed at attracting Trump supporters, Fox News does face one roadblock: Mr. Trump. The former president has maintained his stinging criticism of Fox News, which, he has claimed, betrayed him by calling the election for Mr. Biden.
On Friday, after criticism from Paul Ryan, the former House speaker, Mr. Trump wrote that “Fox totally lost its way and became a much different place” after the Murdochs appointed Mr. Ryan to the Fox Corporation board.
The Associated Press has started a review of its social media policy after more than 150 staff members publicly condemned the firing of a young journalist for violating that policy.
In a memo to its global newsrooms on Monday, The A.P.’s top editors said they had heard the concerns from many journalists over the weekend and were “committed to expanding the conversation taking place about A.P.’s approach to social media.”
The news agency faced a backlash after Emily Wilder, a 22-year-old news associate who had joined the company in Arizona, was dismissed on May 19, three weeks after she was hired.
Ms. Wilder, who graduated from Stanford University in 2020 and had worked at The Arizona Republic, said in a statement on Friday that she had been the subject of a campaign by Stanford College Republicans, whose social media posts drew attention to her pro-Palestine activism at the university. She added that her editors had reassured her she would not be fired for her past advocacy work.
one tweet, she said that “using ‘israel’ but never ‘palestine,’ or ‘war’ but not ‘siege and occupation’ are political choices — yet media make those exact choices all the time without being flagged as biased.”
Dozens of A.P. journalists signed an open letter after Ms. Wilder’s firing, criticizing the news agency and asking for clarification on how she had violated the company’s social media policy.
Today in Business
“The lack of clarity on the violations of the social media policy has made A.P. journalists afraid to engage on social media — often critical to our jobs — in any capacity,” the letter said.
Ten newsroom leaders responded Monday in a memo to the staff announcing a plan to review its guidelines. They said that formal groups would discuss ideas and make recommendations, and a committee of staff members would review the recommendations by Sept. 1. Any changes to the policy would then be raised in the next round of contract negotiations with the union that represents A.P. employees, the News Media Guild.
“One of the issues brought forward in recent days is the belief that restrictions on social media prevent you from being your true self, and that this disproportionately harms journalists of color, L.G.B.T.Q. journalists and others who often feel attacked online,” the memo said.
The editors said in the note that “much of the coverage” of Ms. Wilder’s dismissal “does not accurately portray a difficult decision that we did not make lightly.”
Lauren Easton, a spokeswoman for The A.P., said the company generally refrained from commenting on personnel, but confirmed that Ms. Wilder was dismissed for violating the social media policy.
“We understand that other news organizations may not have made the same decision,” she said. “While many news organizations offer points of view, opinion columnists and editorials, A.P. does not. We don’t express opinion. Our bedrock is fact-based, unbiased reporting.”
It was seven years ago when Waymo discovered that spring blossoms made its self-driving cars get twitchy on the brakes. So did soap bubbles. And road flares.
New tests, in years of tests, revealed more and more distractions for the driverless cars. Their road skills improved, but matching the competence of human drivers was elusive. The cluttered roads of America, it turned out, were a daunting place for a robot.
The wizards of Silicon Valley said people would be commuting to work in self-driving cars by now. Instead, there have been court fights, injuries and deaths, and tens of billions of dollars spent on a frustratingly fickle technology that some researchers say is still years from becoming the industry’s next big thing.
Now the pursuit of autonomous cars is undergoing a reset. Companies like Uber and Lyft, worried about blowing through their cash in pursuit of autonomous technology, have tapped out. Only the most deep pocketed outfits like Waymo, which is a subsidiary of Google’s parent company Alphabet, auto industry giants, and a handful of start-ups are managing to stay in the game.
said that fully functional self-driving cars were just two years away. More than five years later, Tesla cars offered simpler autonomy designed solely for highway driving. Even that has been tinged with controversy after several fatal crashes (which the company blamed on misuse of the technology).
Perhaps no company experienced the turbulence of driverless car development more fitfully than Uber. After poaching 40 robotics experts from Carnegie Mellon University and acquiring a self-driving truck start-up for $680 million in stock, the ride-hailing company settled a lawsuit from Waymo, which was followed by a guilty plea from a former executive accused of stealing intellectual property. A pedestrian in Arizona was also killed in a crash with one of its driverless cars. In the end, Uber essentially paid Aurora to acquire its self-driving unit.
But for the most deep-pocketed companies, the science, they hope, continues to advance one improved ride at a time. In October, Waymo reached a notable milestone: It launched the world’s first “fully autonomous” taxi service. In the suburbs of Phoenix, Ariz., anyone can now ride in a minivan with no driver behind the wheel. But that does not mean the company will immediately deploy its technology in other parts of the country.
Dmitri Dolgov, who recently took over as Waymo’s co-chief executive after the departure of John Krafcik, an automobile industry veteran, said the company considers its Arizona service a test case. Based on what it has learned in Arizona, he said, Waymo is building a new version of its self-driving technology that it will eventually deploy in other geographies and other kinds of vehicles, including long-haul trucks.
The suburbs of Phoenix are particularly well suited to driverless cars. Streets are wide, pedestrians are few and there is almost no rain or snow. Waymo supports its autonomous vehicles with remote technicians and roadside assistance crews who can help get cars out of a tight spot, either via the internet or in person.
“Autonomous vehicles can be deployed today, in certain situations,” said Elliot Katz, a former lawyer who counseled many of the big autonomous vehicle companies before launching a start-up, Phantom Auto, that provides software for remotely assisting and operating self-driving vehicles when they get stuck in difficult positions. “But you still need a human in the loop.”
Self-driving tech is not yet nimble enough to reliably handle the variety of situations human drivers encounter each day. They can usually handle suburban Phoenix, but they can’t duplicate the human chutzpah needed for merging into the Lincoln Tunnel in New York or dashing for an offramp on Highway 101 in Los Angeles.
“You have to peel back every layer before you can see the next layer” of challenges for the technology, said Nathaniel Fairfield, a Waymo software engineer who has worked on the project since 2009, in describing some of the distractions faced by the cars. “Your car has to be pretty good at driving before you can really get it into the situations where it handles the next most challenging thing.”
Like Waymo, Aurora is now developing autonomous trucks as well as passenger vehicles. No company has deployed trucks without safety drivers behind the wheel, but Mr. Urmson and others argue that autonomous trucks will make it to market faster than anything designed to transport regular consumers.
Long-haul trucking does not involve passengers who might not be forgiving of twitchy brakes. The routes are also simpler. Once you master one stretch of highway, Mr. Urmson said, it is easier to master another. But even driving down a long, relatively straight highway is extraordinarily difficult. Delivering dinner orders across a small neighborhood is an even greater challenge.
“This is one of the biggest technical challenges of our generation,” said Dave Ferguson, another early engineer on the Google team who is now president of Nuro, a company focused on delivering groceries, pizzas and other goods.
Mr. Ferguson said that many thought self-driving technology would improve like an internet service or a smartphone app. But robotics is a lot more challenging. It was wrong to claim anything else.
“If you look at almost every industry that is trying to solve really really difficult technical challenges, the folks that tend to be involved are a little bit crazy and little bit optimistic,” he said. “You need to have that optimism to get up everyday and bang your head against the wall to try to solve a problem that has never been solved, and it’s not guaranteed that it ever will be solved.”
Uber and Lyft aren’t entirely giving up on driverless cars. Even though it may not help the bottom line for a long time, they still want to deploy autonomous vehicles by partnering with the companies that are still working on the technology. Lyft now says autonomous rides could arrive by 2023.
“These cars will be able to operate on a limited set of streets under a limited set of weather conditions at certain speeds,” said Jody Kelman, the executive of Lyft. “We will very safely be able to deploy these cars, but they won’t be able to go that many places.”
With vaccination spreading across the United States, social life has begun to bend toward a semblance of normalcy: dinner parties, restaurants, spontaneous encounters with strangers, friends and colleagues on the street or in the office. It’s exciting but also slightly nerve-racking.
“I think there will be a period of heightened anxiety as we meet people face-to-face again,” Adam Mastroianni, a fifth-year Ph.D. student in psychology at Harvard, told me (over the phone). “I’ve heard this from a lot of my friends, that we’re worried: Have we forgotten how to be with other people?”
I’d called Mr. Mastroianni for some help in rediscovering this ancient calculus. In March, he and his colleagues Daniel Gilbert, Gus Cooney and Timothy Wilson published a paper in the Proceedings of the National Academy of Sciences — “Do conversations end when people want them to?” — on one of the stickier aspects of human interaction. Our conversation has been edited for brevity and clarity.

Carmakers have been promising to scrap the internal combustion engine, and now it’s the truckmakers’ turn. But the makers of giant 18-wheelers are taking a different route.
Daimler, the world’s largest maker of heavy trucks, whose Freightliners are a familiar sight on American interstates, said last week that it would convert to zero-emission vehicles within 15 years at the latest, providing another example of how the shift to electric power is reshaping vehicle manufacturing with significant implications for the climate, economic growth and jobs.
The journey away from fossil fuels will play out differently and take longer in the trucking industry than it will for passenger cars. For one thing, zero emission long-haul trucks are not yet available in large numbers.
And different technology may be needed to power the electric motors. Batteries work well for delivery vehicles and other short-haul trucks, which are already on the roads in significant numbers. But Daimler argues that battery power is not ideal for long-haul 18-wheelers, at least with current technology. The weight of the batteries alone subtracts too much from payload, an important consideration for cost-conscious trucking companies.
online presentation Thursday, Daimler executives announced a partnership with Shell to build a “hydrogen corridor” of fueling stations spanning northern Europe. For shorter-haul trucks, Daimler announced a partnership with the Chinese company CATL to develop batteries, and partnerships with Siemens and other companies to install high-voltage charging stations in Europe and the United States.
Trevor Milton, resigned last year facing accusations he had made numerous false assertions about the company’s hydrogen fuel-cell technology.
Nikola at least demonstrated how eager investors are to put their money into hydrogen trucks. Another example is Hyzon, a maker of fuel cells based in Rochester, N.Y., that has begun offering complete trucks and buses. In February, Hyzon was acquired by Decarbonization Plus Acquisition Corporation, a so-called SPAC that raises money before it has any assets.
Tesla unveiled a design for a battery-powered semi truck in 2017, which the company has said it will begin delivering this year. Tesla, Scania and some other truckmakers are skeptical of hydrogen technology, which they regard as too expensive and less energy-efficient.
The traditional truckmakers like Daimler and Volvo have some advantages over the start-ups. Truck buyers tend to be practical hauling firms or drivers who carefully calculate the costs of maintenance and fuel consumption before they make a decision. Managers of big fleets may also be reluctant to take a chance on a manufacturer without a long track record.
President Biden has been promoting electric vehicles, but has not yet defined what that means for the trucking industry.
Trucking companies, which have depended on diesel for most of the last century, will have to revamp their maintenance departments, install their own charging or hydrogen fueling stations in some cases, retrain drivers and learn to plan their routes around hydrogen or electric charging points.
But Mr. Kedzie said that emission-free trucks also had some advantages. Fuel costs for battery-powered vehicles are much lower than for diesel trucks. Maintenance costs may be lower because electric vehicles have fewer moving parts. Drivers like the way electric trucks perform — an important factor at the moment when there is a driver shortage in America.
Many companies that ship a lot of goods, like Walmart or Target, are trying to reduce their carbon footprints and taking an interest in zero-emission trucks. “There are a lot of potential benefits” Mr. Kedzie said.
Daimler says its aim is to make battery-powered short-haul trucks that can compete on cost with diesel by 2025, and long-haul fuel-cell trucks that achieve diesel parity by 2027.
“In that very moment when the customer starts benefiting more from a zero-emission truck than a diesel truck, well, there’s no reason to buy a diesel truck anymore,” Andreas Gorbach, chief technology officer for Daimler’s trucks and buses division, said during the presentation Thursday. “This is the tipping point.”
