BEAUMONT, France — The vines were once demonized for causing madness and blindness, and had been banned decades ago. The French authorities, brandishing money and sanctions, nearly wiped them out.
But there they were. On a hillside off a winding mountain road in a lost corner of southern France, the forbidden crop was thriving. Early one recent evening, Hervé Garnier inspected his field with relief.
In a year when an April frost and disease have decimated France’s overall wine production, Mr. Garnier’s grapes — an American hybrid variety named jacquez, banned by the French government since 1934 — were already turning red. Barring an early-autumn cold snap, all was on track for a new vintage.
“There’s really no reason for its prohibition,” Mr. Garnier said. “Prohibited? I’d like to understand why, especially when you see the prohibition rests on nothing.”
Forgotten Fruits, a group fighting for the legalization of the American grapes. Showing off forbidden vines, including the clinton and isabelle varieties, on a property in the southern Cévennes region, near the town of Anduze, he added, “These vines are ideal for making natural wine.”
Memory of the Vine.” A membership fee of 10 euros, or about $12, yields a bottle.
With the growing threat of climate change and the backlash against the use of pesticides, Mr. Garnier is hoping that the forbidden grapes will be legalized and that France’s wine industry will open up to a new generation of hybrids — as Germany, Switzerland and other European nations already have.
“France is a great wine country,” he said. “To remain one, we have to open up. We can’t get stuck on what we already know.”
EVIA, Greece — Amid twisted cages and scorched trees, Harilaos Tertipis stepped out of his ruined stables dragging the charred corpses of his sheep — burned, like so much else, in the wildfires that have raged across Greece.
As the survivors of his flock huddled together on a roadside hill below, the bells on their necks clanging and their legs singed, he said that if he had stayed with his animals instead of rushing home to protect his family and house, “I wouldn’t be here now.”
scientists have now concluded is irreversible.
before we reach irreversible tipping points.”
But a string of disasters this summer has left many to wonder whether that tipping point is already here, driving home the realization that climate change is no longer a distant threat for future generations, but an immediate scourge affecting rich and poor nations alike.
Turkey and Algeria, virtually no corner of Europe has been untouched by a bewildering array of calamities, whether fire, flood or heat.
Sweltering temperatures have set off wildfires in Sweden, Finland and Norway. Formerly once-in-a-millennium flooding in Germany, Belgium, Switzerland and the Netherlands killed at least 196 people. Places in Italy hit more than 118 degrees this week, while parts of the country were variously scorched by fire, battered by hailstorms or inundated by floods.
“It’s not just Greece,” said Vasilis Vathrakoyiannis, a spokesman for the Greek fire service. “It’s the whole European ecosystem.”
But the shifting epicenter of natural disaster has now fallen on Evia, a densely wooded island northeast of Athens, once best known for its beekeepers and resin producers, its olive groves and seaside resorts, and now a capital of the consequences of a warming planet.
This week, as firefighters scrambled to put out rekindling fires and helicopters dropped seawater to sate licking flames, acres of burned hillsides and fields lay under white ash, as if dusted with snow.
I drove through winding roads riddled with fallen trees and electric wires. Smoke hung low, like a thick fog. The trunks of mangled trees still smoldered and the hive boxes of beekeepers looked like burned end tables abandoned in empty fields. Miles away from the fires, the smoke still left an acrid taste in my mouth. Ash drifted around cafes where waitresses constantly watered down tables and the sun imbued the dense haze with a sickly orange hue.
“We lived in paradise,” said Babis Apostolou, 59, tears in his eyes as he looked over the charred land surrounding his village, Vasilika, on the northern tip of Evia. “Now it’s hell.”
This week, the fires covered new ground. In the southern Peloponnese, where wildfires killed more than 60 people in 2007, a long stretch of fire tore through forest and houses, prompting the evacuation of more than 20 more villages. But many Greeks have refused to leave their homes.
When the police told Argyro Kypraiou, 59, in the Evia village of Kyrinthos to evacuate on Saturday, she stayed. As the trees across the street blazed, she fought the airborne barrage of burning pine cones and flames with a garden hose. When the water ran out she beat back the fire with branches.
“If we had left, the houses would have burned,” she said across from the still smoldering ravine. A truck rolled by and the driver leaned out the window, shouting to her that there was another fire in the field behind her house. “We keep putting out fires,” she shouted back. “We don’t have any other job.”
Kyriakos Mitsotakis, the prime minister of Greece, has called the recent days “among the hardest for our country in decades” and promised to compensate the afflicted and reforest the land. Residents across the seared north of Evia complained that the government had failed to fly water-dropping aircraft out to them fast enough or that it had waited too long to ask the European Union for help.
Greece’s top prosecutor has ordered up an investigation into whether criminal activity could possibly have sparked the fires, perhaps to clear land for development. Many here blamed mysterious arsonists for starting the fire.
“This is arson,” said Mr. Apostolou. “I had heard they want to put in wind turbines.”
Mr. Tertipis said, “I hope the person who set these fires will suffer as much as my animals.”
But it was also possible that the finger-pointing at arsonists stemmed from a feeling of powerlessness and the need to blame someone — anyone — for a crisis that at least some acknowledged was everyone’s fault.
“We all have to make changes,” said Irini Anastasiou, 28, who expected the fires to keep happening around the world as the planet warmed. She looked out from the front desk of her now empty hotel in Pefki, one of the hardest-hit towns, and saw an opaque wall of haze over the sea.
“Usually, you see clear across to the mountains,” she said. “Now you can see nothing.”
The residents of Evia did what they could. In the town of Prokopi, volunteer firefighters set up base in the Forest Museum (“focused on man and his relationship to the forest”).
Hundreds of boxes packed with supplies for the displaced cluttered the log cabin. They brimmed with crackers and cereals and granola bars. Soft stacks of children-and-adult diapers reached up to the windows. Boxes held medicines and burn creams, aloe vera, Flamigel, hydrogel and Flogo Instant Calm Spray, under a sign promoting TWIG, the Transnational Woodland Industries Group.
An international group of emergency workers operated out of the cabin. Some of the 108 firefighters sent by Romania coordinated with Greek Army officials and local authorities to put out the flames. Some volunteers went out with chain saws to cut down trees while those returning leaned against a wall of bottled water and ruminated on what had gone wrong.
Ioannis Kanellopoulos, 62, blamed heavy snowfall during the winter for breaking so many branches and creating so much kindling on the forest floor. But the intense heat did not help.
“When the fire broke out it was 113 degrees in the shade,” he said.
He said the previous benchmark for destruction in the area was a 1977 blaze. This fire had far eclipsed it, he said, and guaranteed that it would not be surpassed for years.
“There’s nothing left to burn,” he said.
“It’s not California,” added his friend Spiros Michail, 52.
That there was nothing left to burn was the island’s common refrain. The punchline to the terrible joke nature had played on them.
But it wasn’t true. There was plenty more to burn.
At night the fires came back, appearing on the dark hillsides in the distance like Chinese lanterns. The fires burned on the sides of the roads like ghostly campsites.
Stylianos Totos, a forest ranger, stood rod straight as he looked through binoculars at a hillside near Ellinika.
“How do we get access to that one,” he called to his colleague in a truck carrying more than a ton of water. He worried that the wind would change direction from east to west and feed the fire with fresh pines. Just before 9 p.m. Tuesday, one of the small flames flared up, lighting all the barren land and twisted branches around it. “Andrea,” he shouted. “Call it in.”
But any help, and any change in global behavior, had come too late for Mr. Tertipis and his flock.
Mr. Tertipis, 60, who lost his mother and suffered permanent scarring on his left arm in 1977’s fire, rushed back from home to his stables before dawn on Sunday. The fire had consumed half his flock, but left a plush green pine tree and verdant field untouched only a few dozen yards away.
“That’s how it is, in five minutes, you live or die,” he said, adding, “the fire just changes all the time.”
For two days he could not answer the phone or do much of anything other than weep. Then he started cleaning up, wading through the remains in galoshes, dragging load after load away, using a sled he fashioned from a hook and a broken refrigerator door.
He had been raising animals all his life, and he said he had no choice but to keep going, no matter how inhospitable the weather around him had become.
“Things may have changed,” he said with a shrug. “What are you going to do? Just give up?”
ATHENS — Firefighters continued to battle blazes across Greece on Saturday after another difficult night that saw thousands more people fleeing their homes and hundreds being evacuated by sea, as southern Europe grapples with one of its worst heat waves in decades.
Wildfires are also still raging in Turkey, which is in its 11th day of trying to extinguish flames that are ravaging its southern coastline and that have killed at least eight people and destroyed hundreds of acres of land.
High winds in Greece hampered nighttime firefighting efforts on Friday as wildfires tore through swaths of forestland north of Athens, the capital, and through mountains and farmland on the island of Evia and on the southern Peloponnese peninsula.
As flames ravaged Evia’s coastline, hundreds of residents and tourists were evacuated by ferry, dramatic scenes of which were captured on video by the National Observatory of Athens’s online weather service, Meteo.
North of the capital, police officers went door to door to urge people to abandon their homes, and they evacuated a detention facility for migrants, a day after moving asylum seekers out of another camp in the area.
At first light on Saturday, firefighters and aircraft from several countries — including Croatia, Cyprus, France, Israel, Sweden and Ukraine — joined their Greek counterparts in battling blazes dotting the mainland and islands. Romania and Switzerland were also sending help, followed by the Czech Republic, Egypt, Germany and Spain.
Fifty-five fires were active around the country, the largest of which were north of Athens, on the island of Evia and in Fokida, in central Greece, according to Nikos Hardalias, the deputy civil protection minister, speaking at a briefing early Saturday afternoon. He added that the situation had improved slightly since Friday, but that fires were constantly rekindling as winds strengthened.
Dozens of firefighting aircraft and thousands of firefighters have been working to control the wildfires, but overnight, TV reports said, flames moved north, reaching a new town and forcing six neighborhoods to evacuate.
Earlier Saturday in Greece, Prime Minister Kyriakos Mitsotakis said his government’s priority was protecting human lives, and then, as possible, people’s properties.
A 38-year-old volunteer firefighter from Ippokrateios Politeia, a settlement north of Athens affected by the fires, died on Thursday of head injuries after being hit by a falling electricity pylon.
More than 20 people have suffered burns, including four firefighters, two of whom were critically injured. President Katerina Sakellaropoulou visited those firefighters on Saturday at a hospital in Athens.
The fires have razed tens of thousands of acres of forestland, but the number of homes that have been destroyed remains unclear.
Officials have said that at least three people have been arrested and are facing arson charges in connection with blazes in Kryoneri, north of Athens; in Fthiotida, in central Greece; and in Kalamata, in southern Greece.
ATHENS — Shells of houses and cars left gutted by flames. Stretches of forest reduced to ash. Tourists evacuated by boat from once idyllic beaches where the skies are thick with smoke. As southern Europe grapples with one of its worst heat waves in decades, deadly forest fires have engulfed stretches of the region, bringing a newly reopened tourism industry to a halt and forcing mass evacuations.
The raging fires pushed residents from their homes in villages on the Greek mainland and islands and across neighboring Turkey, and forced tourists to abandon beachside destinations across the region.
President Recep Tayyip Erdogan over the government’s handling of the deadly disaster, with opponents denouncing the lack of aerial support for the firefighting efforts.
Hundreds of square miles of forest burned as more than 180 fires blazed across the country. At least eight people died, hundreds were injured and dozens lost their homes.
in a video posted on Twitter. “My forest is in flames right now.”
Firefighters were able to control a fire approaching a power plant in Milas after working through the night to save the facility. Trees on the grounds of the power plant were burned, but the main site was not seriously damaged, officials said.
Greece battled multiple large fires across the country that killed scores of people.
While scientists have not yet had time to evaluate the connection between the current wave of extreme temperatures and global warming, it fits an overall trend that has seen climate change play a role in extreme weather in Europe. Research has shown that in major heat waves across Europe in recent summers, climate change has been a significant worsening factor.
Efthymis Lekkas, a professor of natural disaster management at the University of Athens, warned of “an enduring nightmare in August,” and urged the authorities to be ready for potential flooding after the destruction of large stretches of forest.
Greece’s General Secretariat for Civil Protection warned of an “extreme” risk of fires on Friday, as intense winds are forecast to worsen the situation.

TRIPOLI, Lebanon — Rania Mustafa’s living room recalls a not-so-distant past, when the modest salary of a security guard in Lebanon could buy an air-conditioner, plush furniture and a flat-screen TV.
But as the country’s economic crisis worsened, she lost her job and watched her savings evaporate. Now, she plans to sell her furniture to pay the rent and struggles to afford food, much less electricity or a dentist to fix her 10-year-old daughter’s broken molar.
For dinner on a recent night, lit by a single cellphone, the family shared thin potato sandwiches donated by a neighbor. The girl chewed gingerly on one side of her mouth to avoid her damaged tooth.
“I have no idea how we’ll continue,” said Ms. Mustafa, 40, at home in Tripoli, Lebanon’s second-largest city, after Beirut.
The huge explosion one year ago in the port of Beirut, which killed more than 200 people and left a large swath of the capital in shambles, only added to the desperation.
and the central bank unable to keep propping up the currency, as it had for decades, because of a drop in foreign cash flows into the country. Now, the bottom has fallen out of the economy, leaving shortages of food, fuel and medicine.
All but the wealthiest Lebanese have cut meat from their diets and wait in long lines to fuel their cars, sweating through sweltering summer nights because of extended power cuts.
long lines at gas stations, where drivers wait for hours to buy only a few gallons, or none at all if the station runs out.
hampered the investigation into the port explosion, and a billionaire telecoms tycoon, Najib Mikati, is currently the third politician to try to form a government since the last cabinet resigned after the blast.
Mustafa Allouch, the deputy head of the Future Movement, a prominent political party, said, like many other Lebanese, that he feared that the political system, intended to share power between a range of sects, was incapable of addressing the country’s problems.
“I don’t think it will work anymore,” he said. “We have to look for another system, but I don’t know what it is.”
His greatest fear was “blind violence” born out of desperation and rage.
“Looting, shooting, assaults on homes and small shops,” he said. “Why it hasn’t happened by now, I don’t know.”
The crisis has hit the poor hardest.
Five days a week, scores of people line up for free meals from a charity kitchen in Tripoli, some equipped with cut off shampoo bottles to carry their food because they can’t afford regular containers.
Robert Ayoub, the project’s head, said demand is going up, donations from inside Lebanon are going down, and the newcomers represent a new kind of poor: soldiers, bank employees and civil servants whose salaries have lost the bulk of their value.
In line on a recent day were a laborer who had walked an hour from home because he couldn’t afford transportation; a brick layer whose work had dried up; and Dunia Shehadeh, an unemployed housekeeper who picked up a tub of pasta and lentil soup for her husband and three children.
“This will hardly be enough for them,” she said.
The country’s downward spiral has set off a new wave of migration, as Lebanese with foreign passports and marketable skills seek better fortune abroad.
“I can’t live in this place, and I don’t want to live in this place,” said Layal Azzam, 39, before catching a flight to Saudi Arabia from Beirut’s international airport.
She and her husband had returned to Lebanon from abroad a few years ago and invested $50,000 in a business. But she said that it had failed and that she worried they would struggle to find care if their children got sick.
“There’s no electricity. They could cut the water. Prices are high. Even if someone sends you money from abroad, it doesn’t last,” she said. “There are too many crises.”

Mr. Sweetat is prepared to make compromises in a land where few are ready to do so. He believes cooperation in pursuit of shared prosperity, however difficult, is the only way forward. “If we don’t like it,” he said, “we can pack our bags and go to Switzerland.”
I asked him if he felt like an equal citizen in Israel.
“Of course, I don’t feel equal,” he said, “but I can achieve everything I want.”
Still, he said, “I don’t see new Arab villages being built. I don’t have enough space in my own village. I wanted to buy a piece of land near Tarshiha, but I couldn’t. I want my son, who is 2, to grow up here. Ask the country why I can’t find land here.”
“So, you can’t achieve everything you want?” I asked.
“There are things you can’t change, but we can improve them. The change can start from people.”
Overcoming Mutual Incomprehension
When Tal Becker, the legal adviser to the Israeli Foreign Ministry, drafted the preamble to the normalization treaty between Israel and the United Arab Emirates last year, he expected pushback on this clause:
“Recognizing that the Arab and Jewish peoples are descendants of a common ancestor, Abraham, and inspired,in that spirit, to foster in the Middle East a reality in which Muslims, Jews, Christians and peoples of all faiths, denominations, beliefs and nationalities live in, and are committed to, a spirit of coexistence.”
There was no dissent, despite the fact that the wording made clear that both Jews and Arabs belong in the Middle East.
A widespread view among Palestinians and throughout the Arab world has long been, on the contrary, that Israel and its Jewish population represent an illicit colonial projection into the Middle East that will one day end.
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.
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:
February and May 2014
A 7-year-old boy dead after falling ill in a flooded home in Surrey. A kayaker drowned on a swollen Welsh river.A coastal railroad ripped up by waves in Cornwall.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 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.
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.”
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.”
military threats to human rights concerns. Some were longstanding, others of newer vintage.
During the Cold War, the prospect of nuclear annihilation led to historic treaties and a framework that kept the world from blowing itself up. At this meeting, for the first time, cyberweapons — with their own huge potential to wreak havoc — were at the center of the agenda.
But Mr. Putin’s comments to the media suggested the two leaders did not find much common ground.
In addition to his denials that Russia had played a destabilizing role in cyberspace, he also took a hard line on human rights in Russia.
He said Mr. Biden had raised the issue, but struck the same defiant tone on the matter in his news conference as he has in the past. The United States, Mr. Putin said, supports opposition groups in Russia to weaken the country, since it sees Russia as an adversary.
“If Russia is the enemy, then what organizations will America support in Russia?” Mr. Putin asked. “I think that it’s not those who strengthen the Russian Federation, but those that contain it — which is the publicly announced goal of the United States.”
President Biden said on Wednesday that “I did what I came to do” in his first summit meeting with President Vladimir V. Putin of Russia.
Speaking after the summit in Geneva, Mr. Biden said the two leaders had identified areas of mutual interest and cooperation. But he said he had also voiced American objections to Russia’s behavior on human rights, and warned that there would be consequences to cyberattacks on the United States.
Any American president representing the country’s democratic values, Mr. Biden said, would be obliged to raise issues of human rights and freedoms. And so he said had discussed with Mr. Putin his concerns over the imprisonment of the Russian opposition leader Aleksei A. Navalny and warned there would be “devastating” consequences if Mr. Navalny were to die in prison.
Mr. Biden also brought up the detentions of two American citizens in Russia, Paul Whelan and Trevor Reed, he said.
On the issue of cybersecurity, Mr. Biden said he had argued that certain parts of the infrastructure need to be off limits to cyberattacks. He said he had provided Mr. Putin with a list of critical areas, like energy, that must be spared. Mr. Biden also said the two leaders had agreed to enlist experts in both countries to discuss what should remain off limits and to follow up on specific cases.
“We need to have some basic rules of the road,” Mr. Biden told reporters after the summit.
And if Russia continues to violate what he called the basic norms of responsible behavior, he said, “We will respond.”
Mr. Biden made clear that, during his discussions with Mr. Putin, there were no threats, no talk of military intervention and no mention of what specific retaliation the United States would take in such cases. But Mr. Biden said that the United States was fully capable of responding with its own cyberattacks —“and he knows it.”
Mr. Biden said “there’s much more work to do,” but declared over the course of his weeklong European trip, he had shown that “the United States is back.”
He also said Russia stood to lose internationally if it continued to meddle in elections. “It diminishes the standing of a nation,”Mr. Biden said.
President Vladimir V. Putin on Wednesday repeated well-worn denials of Russian mischief and tropes about American failings, as he spoke to the press after his first summit with President Biden.
But between those familiar lines, he left the door open to deeper engagement with Washington than the Kremlin had been willing to entertain in recent years. On issues like cybersecurity, nuclear weapons, diplomatic spats and even prisoner exchanges, Mr. Putin said he was ready for talks with the United States, and he voiced unusual optimism about the possibility of achieving results.
“We must agree on rules of behavior in all the spheres that we mentioned today: That’s strategic stability, that’s cybersecurity, that’s resolving questions connected to regional conflicts,” Mr. Putin said at a nearly hourlong news conference after the summit. “I think that we can find agreement on all this — at least I got that sense given the results of our meeting with President Biden.”
Mr. Putin’s focus on “rules of behavior” sounded a lot like the “guardrails” that American officials have said they hope to agree on with Russia in order to stabilize the relationship. “Strategic stability” is the term both sides use to refer to nuclear weapons and related issues.
To be sure, there is no guarantee that the United States and Russia will make progress on those fundamental issues, and American officials fear Russian offers of talks could be efforts to tie key questions up in committees rather than set clear red lines. But in recent years, substantive dialogue between the two countries has been rare, making Wednesday’s promises of new consultations significant.
But Mr. Putin fell back on familiar Kremlin talking points to bat away criticisms, pointing to supposed human rights violations in the United States and denying Russian complicity in cyberattacks. He also refused to budge in response to questions over his repression of dissent inside Russia and the imprisonment of the opposition leader Aleksei A. Navalny. As he has said in the past, he repeated that the Kremlin does not see domestic politics as up for negotiation or discussion.
“If you ignore the tiresome whataboutism, there were some real outcomes,” said Samuel Charap, a senior political scientist at the RAND Corporation in Arlington, Va. “Russia is not in the habit of confessing its sins and seeking forgiveness. Particularly under Putin.”
The main outcomes to Mr. Charap were the agreement on U.S.-Russian dialogue on strategic stability and cybersecurity, as well as the agreement for American and Russian ambassadors to return to their posts in Moscow and Washington. Mr. Putin also said there was “potential for compromise” on the issue of several Americans imprisoned in Russia and Russians imprisoned in the United States.
To tout his renewed willingness to talk — while acknowledging the uncertainty ahead — Mr. Putin quoted from Russian literature.
“Leo Tolstoy once said: ‘There is no happiness in life — there are only glimmers of it,’” Mr. Putin said. “I think that in this situation, there can’t be any kind of family trust. But I think we’ve seen some glimmers.”
After President Biden met his Russian counterpart on Wednesday, the two men did not face the news media at a joint news conference.
President Vladimir V. Putin of Russia spoke first, followed by Mr. Biden, in separate news conferences, a move intended by the White House to deny the Russian leader an international platform like the one he received during a 2018 summit in Helsinki with President Donald J. Trump.
“We expect this meeting to be candid and straightforward, and a solo press conference is the appropriate format to clearly communicate with the free press the topics that were raised in the meeting,” a U.S. official said in a statement sent to reporters this weekend, “both in terms of areas where we may agree and in areas where we have significant concerns.”
Top aides to Mr. Biden said that during negotiations over the meetings the Russian government was eager to have Mr. Putin join Mr. Biden in a news conference. But Biden administration officials said that they were mindful of how Mr. Putin seemed to get the better of Mr. Trump in Helsinki.
At that news conference, Mr. Trump publicly accepted Mr. Putin’s assurances that his government did not interfere with the 2016 election, taking the Russian president’s word rather than the assessments of his own intelligence officials.
The spectacle in 2018 drew sharp condemnations from across the political spectrum for providing an opportunity for Mr. Putin to spread falsehoods. Senator John McCain at the time called it “one of the most disgraceful performances by an American president in memory.”
Piggybacking on the attention to Russia with the Biden-Putin meeting on Wednesday, the European Union issued a long and pessimistic report on the state of relations between Brussels and Moscow.
“There is not much hope for better relations between the European Union and Russia anytime soon,” said Josep Borrell Fontelles, the E.U.’s foreign policy chief, introducing the report. It was prepared in advance of a summit meeting of European leaders next week at which the bloc’s future policy toward Russia will be on the agenda.
That discussion has been delayed several times by other pressing issues, including the pandemic.
“Under present circumstances, a renewed partnership between the E.U. and Russia, allowing for closer cooperation, seems a distant prospect,” Mr. Borrell said in a statement, introducing the 14-page report prepared by the European Commission.
The report urges the 27-member bloc to simultaneously “push back” against Russian misbehavior and violations of international law; “constrain” Russia’s efforts to destabilize Europe and undermine its interests, especially in the Western Balkans and neighboring post-Soviet states; and “engage” with Russia on common issues like health and climate, “based on a strong common understanding of Russia’s aims and an approach of principled pragmatism.”
The ambition, Mr. Borrell said, is to move gradually “into a more predictable and stable relationship,” a similar goal to that expressed by the Biden administration.
Mr. Borrell had an embarrassing visit to Moscow in February as he began to prepare the report. He stood by without reacting in a joint news conference as his Russian counterpart, Foreign Minister Sergey Lavrov, called the European Union an “unreliable partner.”
As they were meeting, Moscow announced that diplomats from Germany, Poland and Sweden had been expelled for purportedly participating in “illegal protests” to support the jailed opposition politician Aleksei A. Navalny, a fact Mr. Borrell discovered only later through social media.
He defended the trip, telling the European Parliament that he “wanted to test whether the Russian authorities are interested in a serious attempt to reverse the deterioration of our relations and seize the opportunity to have a more constructive dialogue. The answer has been clear: No, they are not.”
Relations have worsened since then with overt Russian support for a crackdown against democracy and protests in Belarus.
Even before the summit between the United States and Russia got underway on Wednesday, Ukrainian officials played down the prospect for a breakthrough on one of the thornier issues on the agenda: ending the war in eastern Ukraine, the only active conflict in Europe today.
Ukraine said it would not accept any arrangements made in Geneva between President Biden and President Vladimir V. Putin on the war, which has been simmering for seven years between Russian-backed separatists and the Ukrainian Army, officials said.
Before the summit’s start, Dmitri S. Peskov, the Kremlin’s spokesman, said that Ukraine’s entry into NATO would represent a “red line” for Russia that Mr. Putin was prepared to make plain on Wednesday. Mr. Biden said this week that Ukraine could join NATO if “they meet the criteria.”
The Ukrainian government has in recent years dug in its heels on a policy of rejecting any negotiation without a seat at the table after worry that Washington and Moscow would cut a deal in back-room talks. The approach has remained in place with the Biden administration.
“It is not possible to decide for Ukraine,” President Volodymyr Zelensky said on Monday. “So there will be no concrete result” in negotiations in Geneva, he said.
Ukraine’s foreign minister drove the point home again on Tuesday.
“We have made it very clear to our partners that no agreement on Ukraine reached without Ukraine will be recognized by us,” Dmytro Kuleba, the foreign minister, told journalists. Ukraine, he said, “will not accept any scenarios where they will try to force us to do something.”
Ukraine will have a chance for talks with the United States. Mr. Biden has invited Mr. Zelensky to a meeting in the White House in July, when a recent Russian troop buildup along the Ukrainian border is sure to be on the agenda.
Russia massed more than 100,000 troops along the Ukrainian border this spring. Despite an announcement in Moscow of a drawdown, both Ukrainian and Western governments say that only a few thousand soldiers have departed, leaving a lingering risk of a military escalation over the summer.
With Donald J. Trump in Osaka, Japan, in 2019.
With Barack Obama in New York in 2015.
With George W. Bush in Washington in 2005.
With Bill Clinton in Moscow in 2000.
If President Biden wanted an example of a summit that did not go according to plan, he needed only to look back to 2018.
That year, President Donald J. Trump flew to Helsinki to meet President Vladimir V. Putin of Russia, the first face-to-face meeting between the two and a highly anticipated moment given the then-ongoing investigations of Russian interference and cooperation with Mr. Trump’s 2016 presidential campaign.
It might have been a chance for Mr. Trump to push back against those accusations by offering a forceful denunciation of Russia’s actions in private, and again during a joint news conference by the two men.
Instead, standing on the stage by Mr. Putin’s side, Mr. Trump dismissed the conclusions by U.S. intelligence agencies about Russian meddling and said, in essence, that he believed Mr. Putin more than he did the C.I.A. and other key advisers
“They said they think it’s Russia,” Mr. Trump said. “I have President Putin; he just said it’s not Russia.” He added that he didn’t see any reason Russia would have been responsible for hacks during the 2016 election. “President Putin was extremely strong and powerful in his denial today.”
It was the kind of jaw-dropping assertion that U.S. administrations usually strive to avoid in the middle of highly scripted presidential summits. Critics lashed out at Mr. Trump for undermining his own government and for giving aid and comfort to an adversary. Even Republican allies of the president issued harsh denunciations.
“It is the most serious mistake of his presidency and must be corrected — immediately,” said Newt Gingrich, the former Republican House speaker and a staunch supporter of Mr. Trump.
There was nothing about the one day Helsinki summit that was normal. Mr. Putin and Mr. Trump were so chummy that the Russian president gave Mr. Trump a soccer ball to take home as a gift. Mr. Trump thanked him and bounced the ball to Melania Trump, the first lady, in the front row, saying he would take it home to give it to his son, Barron.
(Sarah Sanders, the White House press secretary at the time, later issued a statement saying that the ball — like all gifts — had been examined to make sure it had not been bugged with listening devices.)
In a statement issued as Mr. Biden headed to Europe last week, Mr. Trump once again called his meeting with Mr. Putin “great and very productive” and he defended supporting the Russian president over his intelligence aides.
“As to who do I trust, they asked, Russia or our ‘Intelligence’ from the Obama era,” he said in a statement. “The answer, after all that has been found out and written, should be obvious. Our government has rarely had such lowlifes as these working for it.”
The former president also took a cheap shot at his successor in the statement, warning him not to “fall asleep during the meeting.”
One thing was certain — Mr. Biden did not follow through on Mr. Trump’s request that when Mr. Biden met with Mr. Putin “please give him my warmest regards!”
In the United States, fireworks lit up the night sky in New York City on Tuesday, a celebration meant to demonstrate the end of coronavirus restrictions. California, the most populous state, has fully opened its economy. And President Biden said there would be a gathering at the White House on July 4, marking what America hopes will be freedom from the pandemic.
Yet this week the country’s death toll passed 600,000 — a staggering loss of life.
In Russia, officials frequently say that the country has handled the coronavirus crisis better than the West and that there have been no large-scale lockdowns since last summer.
But in the week that President Vladimir V. Putin met with Mr. Biden for a one-day summit, Russia has been gripped by a vicious new wave of Covid-19. Hours before the start of the summit on Wednesday, the city of Moscow announced that it would be mandating coronavirus vaccinations for workers in service and other industries.
“We simply must do all we can to carry out mass vaccination in the shortest possible time period and stop this terrible disease,” Sergey S. Sobyanin, the mayor of Moscow, said in a blog post. “We must stop the dying of thousands of people.”
It was a reversal from prior comments from Mr. Putin, who said on May 26 that “mandatory vaccination would be impractical and should not be done.”
Mr. Putin said on Saturday that 18 million people had been inoculated in the country — less than 13 percent of the population, even though Russia’s Sputnik V shots have been widely available for months.
The country’s official death toll is nearly 125,000, according to Our World in Data, and experts have said that such figures probably vastly underestimate the true tally.
While the robust United States vaccination campaign has sped the nation’s recovery, the virus has repeatedly confounded expectations. The inoculation campaign has also slowed in recent weeks.
Unlike many of the issues raised at Wednesday’s summit, and despite the scientific achievement that safe and effective vaccines represent, the virus follows its own logic — mutating and evolving — and continues to pose new and unexpected challenges for both leaders and the world at large.
The conflict in Syria — which has now raged for 10 years and counting — was on the meeting agenda for President Biden and President Vladimir V. Putin of Russia as they met on Wednesday.
Since the start of the war, Russia has supported President Bashar al-Assad and his forces, and in 2015 it launched a military intervention with ground forces in the country to prop up the then-flailing government. In the years since, government forces have regained control of much of the country, with the support of Russia and Iran, as Mr. al-Assad’s forced tamped down dissent and carried out brutal attacks against Syrian civilians.
The United States also became deeply involved in the conflict, backing Kurdish forces in the country’s north and conducting airstrikes in the fight against the Islamic State. It has maintained a limited military presence there. Both the United States and Russian forces have found themselves on opposite sides of the multifaceted conflict on numerous occasions.
After years of failed attempts at peace in Syria as the humanitarian toll has continued to mount, Lina Khatib, the director of the Middle East and North Africa Program at Chatham House, a British think tank, said the moment could be ripe for the two major powers to chart a path forward.
She said that “despite taking opposing sides in the Syrian conflict, there is potential for a US-Russian compromise,” and that the summit could be the best place to begin that process.
“The Biden administration must not waste the opportunity that the U.S.-Russian summit presents on Syria,” Ms. Khatib wrote in a recent piece before the meeting in Geneva. “While the focus of various U.S. government departments working on Syria is on the delivery of cross-border aid, fighting the Islamic State and planning an eventual exit for U.S. troops, all these problems are products of the ongoing conflict, and solving them requires a comprehensive strategy to end it.”
American and Russian reporters engaged in a shoving match on Wednesday outside the villa where President Biden and President Vladimir V. Putin of Russia were meeting, stranding much of the press outside when the two leaders began talking.
The chaotic scrum erupted moments after Mr. Biden and Mr. Putin shook hands and waved to reporters before closed-door meetings with a handful of aides.
President Guy Parmelin of Switzerland had just welcomed the leaders “in accordance with its tradition of good offices” to “promote dialogue and mutual understanding.”
But shortly after the two leaders entered the villa, reporters from both countries rushed the side door, where they were stopped by Russian and American security and government officials from both countries. There was screaming and pushing as both sides tried to surge in, with officials yelling for order.
White House officials succeeded in getting nine members of their 13-member press pool into the library where Mr. Biden and Mr. Putin were seated against a backdrop of floor-to-ceiling books, along with each of their top diplomats and translators. The two leaders had already begun to make very brief remarks before reporters were able to get in the room.
Inside, more scuffling erupted — apparently amusing to the two leaders — as Russian officials told photographers that they could not take pictures and one American reporter was shoved to the ground. The two leaders waited, at moments smiling uncomfortably, for several minutes before reporters were pushed back out of the room as the summit meeting began.
“It’s always better to meet face to face,” Mr. Biden said to Mr. Putin as the commotion continued.
Chaotic scenes are not uncommon when reporters from multiple countries angle for the best spot to view a world leader, often in cramped spaces and with government security and handlers pushing them to leave quickly.
But even by those standards the scene outside the villa in this usually bucolic venue was particularly disruptive. Russian journalists quickly accused the Americans for trying to get more people into the room than had been agreed to, but it appeared that the Russians had many more people than the 15 for each side that had been negotiated in advance.
“The Americans didn’t go through their door, caused a stampede,” one Russian reporter posted on Telegram.
In fact, reporters from both countries had been told to try to go through a single door, and officials for both countries at times were stopping all of the reporters from entering, telling them to move back and blocking the door.
When American officials tried to get White House reporters inside, the Russian security blocked several of them.
Wednesday’s Geneva summit got off to an auspicious start: President Vladimir V. Putin of Russia landed on time.
His plane landed at about 12:30 p.m., an hour before he was set to meet President Biden, who had arrived in Geneva the previous evening. Mr. Putin is known for making world leaders wait — sometimes hours — for his arrival, one way to telegraph confidence and leave an adversary on edge.
But this time Mr. Putin did not resort to scheduling brinkmanship.
The summit’s start was laced with delicate choreography: Mr. Putin arrived first, straight from the airport, and was greeted on the red carpet in front of a lakeside villa by President Guy Parmelin of Switzerland. About 15 minutes later, Mr. Biden arrived in his motorcade, shook hands with Mr. Parmelin and waved to reporters.
The Swiss president welcomed the two leaders, wishing them “fruitful dialogue in the interest of your two countries and the whole world.” He then stepped aside, allowing Mr. Biden and Mr. Putin to approach each other, smiling, and shake hands.
Russian officials on Wednesday sought to put a positive last-minute spin on the meeting.
“This is an extremely important day,” a deputy foreign minister, Sergey Ryabkov, told the RIA Novosti state news agency hours before the summit’s start. “The Russian side in preparing for the summit has done the utmost for it to turn out positive and have results that will allow the further deterioration of the bilateral relationship to be halted, and to begin moving upwards.”
Even before Mr. Putin landed, members of his delegation had arrived at the lakeside villa where the meeting is being held. They included Foreign Minister Sergey V. Lavrov, who joined Mr. Putin in a small-group session with Mr. Biden and Secretary of State Antony J. Blinken at the start of the summit; and Valery V. Gerasimov, Russia’s most senior military officer.
Police officers from across Switzerland — the words “police,” “Polizei” and “polizia” on their uniforms reflecting the country’s multilingual cantons — cordoned off much of the center of Geneva on Wednesday.
The city’s normally bustling lakefront was off limits, and the park where President Biden and Mr. Putin were meeting was protected by razor wire and at least one armored personnel carrier.
Inside the leafy Parc la Grange, overlooking Lake Geneva, the police directed journalists to two separate press centers — one for those covering Mr. Putin, one for those covering Mr. Biden. As the reporters waited for the leaders to arrive, a Russian radio reporter went on air and intoned that Lake Geneva had become “a lake of hope.”
A storied villa on the shores of Lake Geneva is sometimes described as having “a certain sense of mystery about it,” but there was little mystery this week about why the mansion and the park surrounding it were closed off.
Visitors were coming.
The Villa la Grange, an 18th-century manor house at the center of Parc la Grange, was the site of the meeting on Wednesday between President Biden and President Vladimir V. Putin.
Set in one of Geneva’s largest and most popular parks, the site is known not just for its lush gardens, but also for its role as a setting for important moments in the struggle between war and peace.
In 1825, the villa’s library — home to over 15,000 works and the only room to retain the villa’s original decorative features — hosted dignitaries of a European gathering that aimed to help Greeks fighting for independence.
Designed by the architect Jean-Louis Bovet and completed in 1773, the villa was owned by the Lullin family and primarily used as a summer residence before it was bought by a merchant, François Favre, in 1800.
It cemented its place in history in 1864, when it was the site of a closing gala for officials who signed the original 1864 Geneva Convention, presided over by Henri Dunant, a founder of the International Red Cross. An attempt to ameliorate the ravages of war on both soldiers and civilians, it set minimum protections for people who are victims of armed conflict.
After World War II, a new draft of the conventions was signed in an attempt to address gaps in international humanitarian law that the conflict had exposed.
In 1969, Pope Paul VI, who traveled to the park to celebrate Mass for a congregation of tens of thousands, pointed to the villa’s history as he spoke about the risk of nuclear conflagration.
He spoke about the opposing forces of love and hate and called for “generous peacemakers.”
Sarah Cavey, a real estate agent in Denver, was thrilled last fall when Colorado introduced an app to warn people of possible coronavirus exposures.
Based on software from Apple and Google, the state’s smartphone app uses Bluetooth signals to detect users who come into close contact. If a user later tests positive, the person can anonymously notify other app users whom the person may have crossed paths with in restaurants, on trains or elsewhere.
Ms. Cavey immediately downloaded the app. But after testing positive for the virus in February, she was unable to get the special verification code she needed from the state to warn others, she said, even after calling Colorado’s health department three times.
“They advertise this app to make people feel good,” Ms. Cavey said, adding that she had since deleted the app, called CO Exposure Notifications, in frustration. “But it’s not really doing anything.”
announced last year that they were working together to create a smartphone-based system to help stem the virus, their collaboration seemed like a game changer. Human contact tracers were struggling to keep up with spiking virus caseloads, and the trillion-dollar rival companies — whose systems run 99 percent of the world’s smartphones — had the potential to quickly and automatically alert far more people.
Soon Austria, Switzerland and other nations introduced virus apps based on the Apple-Google software, as did some two dozen American states, including Alabama and Virginia. To date, the apps have been downloaded more than 90 million times, according to an analysis by Sensor Tower, an app research firm.
But some researchers say the companies’ product and policy choices limited the system’s usefulness, raising questions about the power of Big Tech to set global standards for public health tools.
Stephen Farrell and Doug Leith, computer science researchers at Trinity College in Dublin, wrote in a report in April on Ireland’s virus alert app.
CA Notify in December, about 65,000 people have used the system to alert other app users, the state said.
“Exposure notification technology has shown success,” said Dr. Christopher Longhurst, the chief information officer of UC San Diego Health, which manages California’s app. “Whether it’s hundreds of lives saved or dozens or a handful, if we save lives, that’s a big deal.”
In a joint statement, Apple and Google said: “We’re proud to collaborate with public health authorities and provide a resource — which many millions of people around the world have enabled — that has helped protect public health.”

Based in part on ideas developed by Singapore and by academics, Apple and Google’s system incorporated privacy protections that gave health agencies an alternative to more invasive apps. Unlike virus-tracing apps that continuously track users’ whereabouts, the Apple and Google software relies on Bluetooth signals, which can estimate the distance between smartphones without needing to know people’s locations. And it uses rotating ID codes — not real names — to log app users who come into close contact for 15 minutes or more.
said last year in a video promoting the country’s alert system, called Corona-Warn-App.
But the apps never received the large-scale efficacy testing typically done before governments introduce public health interventions like vaccines. And the software’s privacy features — which prevent government agencies from identifying app users — have made it difficult for researchers to determine whether the notifications helped hinder virus transmission, said Michael T. Osterholm, the director of the Center for Infectious Disease Research and Policy at the University of Minnesota.
“The apps played virtually no role at all in our being able to investigate outbreaks that occurred here,” Dr. Osterholm said.
Some limitations emerged even before the apps were released. For one thing, some researchers note, exposure notification software inherently excludes certain vulnerable populations, such as elderly people who cannot afford smartphones. For another thing, they say, the apps may send out false alarms because the system is not set up to incorporate mitigation factors like whether users are vaccinated, wearing masks or sitting outside.
Proximity detection in virus alert apps can also be inconsistent. Last year, a study on Google’s system for Android phones conducted on a light-rail tram in Dublin reported that the metal walls, flooring and ceilings distorted Bluetooth signal strength to such a degree that the chance of accurate proximity detection would be “similar to that of triggering notifications by randomly selecting” passengers.
Kimbley Craig, the mayor of Salinas, Calif. Last December, when virus rates there were spiking, she said, she downloaded the state’s exposure notification app on her Android phone and soon after tested positive for Covid-19. But after she entered the verification code, she said, the system failed to send an alert to her partner, whom she lives with and who had also downloaded the app.
“If it doesn’t pick up a person in the same household, I don’t know what to tell you,” Mayor Craig said.
In a statement, Steph Hannon, Google’s senior director of product management for exposure notifications, said that there were “known challenges with using Bluetooth technology to approximate the precise distance between devices” and that the company was continuously working to improve accuracy.
The companies’ policies have also influenced usage trends. In certain U.S. states, for instance, iPhone users can activate the exposure notifications with one click — by simply turning on a feature on their settings — but Android users must download a separate app. As a result, about 9.6 million iPhone users in California had turned on the notifications as of May 10, the state said, far outstripping the 900,000 app downloads on Android phones.
Google said it had built its system for states to work on the widest range of devices and be deployed as quickly as possible.
Some public health experts acknowledged that the exposure alert system was an experiment in which they, and the tech giants, were learning and incorporating improvements as they went along.
One issue they discovered early on: To hinder false alarms, states verify positive test results before a person can send out exposure notifications. But local labs can sometimes take days to send test results to health agencies, limiting the ability of app users to quickly alert others.
In Alabama, for instance, the state’s GuideSafe virus alert app has been downloaded about 250,000 times, according to Sensor Tower. But state health officials said they had been able to confirm the positive test results of only 1,300 app users. That is a much lower number than health officials would have expected, they said, given that more than 10 percent of Alabamians have tested positivefor the coronavirus.
“The app would be a lot more efficient if those processes were less manual and more automated,” said Dr. Scott Harris, who oversees the Alabama Department of Public Health.
Colorado, which automatically issues the verification codes to people who test positive, has reported higher usage rates. And in California, UC San Diego Health has set up a dedicated help line that app users can call if they did not receive their verification codes.
Dr. Longhurst, the medical center’s chief information officer, said the California app had proved useful as part of a larger statewide public health push that also involved mask-wearing and virus testing.
“It’s not a panacea,” he said. But “it can be an effective part of a pandemic response.”
