LONDON (AP) — Britain’s record-breaking heatwave has spurred calls for the government to speed up efforts to adapt to a changing climate, especially after wildfires created the busiest day for London firefighters since bombs rained down on the city during World War II.

The country got a break Wednesday from the dry, hot weather that is gripping much of Europe as cooler air moved in from the west. Forecasters predict London will reach a high of 26 degrees Celsius (79 Fahrenheit) on Wednesday, down from the national record 40.3 C (104.4 F) set Tuesday at Coningsby in eastern England.

Even so, travel was disrupted for a third day as rail operators repaired damage caused by the heat, and firefighters continue to mop up hotspots at the scene of Tuesday’s fires.

Britain needs to prepare for similar heatwaves in the future because manmade carbon emissions have already changed the climate, said Professor Stephen Belcher, chief scientist at the Met Office, the U.K.’s national weather service. Only aggressive emissions reductions will reduce the frequency of such events, he said.

“Everything is still to play for, but we should adapt to the kind of events we saw yesterday as an occasional extreme event,” Baker told the BBC.

Climate scientists have been surprised by the speed at which temperatures in Britain have risen in recent years and the widespread area affected by this week’s event. Thirty-four locations around the U.K. on Tuesday broke the country’s previous record-high temperature of 37.8 C (100 F), set in 2019.

The weather walloped a country where few homes, schools or small businesses have air conditioning and infrastructure such as railroads, highways and airports aren’t designed to cope with such temperatures. Thirteen people, including seven teenage boys, are believed to have died trying to cool off after getting into difficulty in rivers, reservoirs and lakes.

Fifteen fire departments declared major incidents as more than 60 properties around the country were destroyed on Tuesday, Cabinet Office Minister Kit Malthouse told the House of Commons.

One of the biggest fires was in Wennington, a village on the eastern outskirts of London, where a row of houses was destroyed by flames that raced through tinder-dry fields nearby. Resident Tim Stock said he and his wife fled after the house next door caught fire and the blaze rapidly spread.

“It was like a war zone,″ he said. “Down the actual main road, all the windows had exploded out, all the roofs had caved, it was like a scene from the Blitz.”

The London Fire Brigade received 2,600 calls Tuesday, compared with the normal figure of about 350, Mayor Sadiq Khan said, adding that it was the department’s busiest day since the World War II. Despite lower temperatures on Wednesday, the fire danger remains high because hot, dry weather has parched grasslands around the city, Khan said.

“Once it catches fire it spreads incredibly fast, like wildfires like you see in movies or in fires in California or in parts of France,” Khan told the BBC.

Phil Gerigan, leader of the National Fire Chiefs Council’s resilience group, said wildfires are an emerging threat tied to climate change that is stretching the capacity of fire departments. Britain may need to expand its capacity to fight wildfires, adding more aerial tankers and helicopters, he told the BBC.

“As we look towards the future, it’s certainly something that the U.K. government and fire and rescue services need to consider,” he said. “Have we got the capability, the assets, to be able to meet what is a significantly emerging demand?”

Wildfires continue to spread destruction in other parts of Europe. Nearly 500 firefighters struggled to contain a large wildfire that threatened hillside suburbs outside Athens for a second day as fires burned across a southern swath of the continent.

A respite from the severe heat helped improve conditions in France, Spain and Portugal, countries that have battled blazes for days.

Britain’s travel network also suffered during the hot weather, with Luton Airport briefly shut down by a heat-damaged runway and trains forced to run at reduced speeds because of concerns the heat would warp rails or interrupt power supplies.

Some disruptions remained Wednesday, with the main train line from London to Edinburgh closed as crews worked to repair power lines and signaling equipment damaged by fire.

Among those stranded was Lee Ball, 46, who was trying to travel with his wife, Libby, and 10-year-old daughter, Amelie, from Worcestershire to London to get to Brussels for an Ed Sheeran concert. Their train was cancelled with less than 30 minutes notice, so they drove to another station — and waited.

“I’ve been up since 4:30 a.m., anxious, trying to get an answer from anywhere we can,” he said.

Communication from the train companies has been “appalling,” he said.

LONDON (AP) — Britain shattered its record for highest temperature ever registered Tuesday amid a heat wave that has seared swaths of Europe — and the national weather forecaster predicted it would get hotter still in a country ill prepared for such extremes.

The typically temperate nation was just the latest to be walloped by unusually hot, dry weather that has triggered wildfires from Portugal to the Balkans and led to hundreds of heat-related deaths. Images of flames racing toward a French beach and Britons sweltering — even at the seaside — have driven home concerns about climate change.

The U.K. Met Office registered a provisional reading of 40.2 degrees Celsius (104.4 degrees Fahrenheit) at Heathrow Airport in early afternoon — breaking the record set just an hour earlier and with hours of intense sunshine still to go. Before Tuesday, the highest temperature recorded in Britain was 38.7 C (101.7 F), set in 2019.

As the nation watched the mercury rise with a combination of horror and fascination, the forecaster warned temperatures could go higher still.

The sweltering weather has disrupted travel, health care and schools in a country not prepared for such extremes. Many homes, small businesses and even public buildings, including hospitals, don’t even have air conditioning, a reflection of how unusual such heat is in the country better known for rain and mild temperatures.

The intense heat since Monday has damaged the runway at London’s Luton airport, forcing it to shut for several hours, and warped a main road in eastern England, leaving it looking like a “skatepark,” police said. Major train stations were shut or near-empty on Tuesday, as trains were canceled or ran at low speeds out of concern rails could buckle.

Electric fans cooled the traditional mounted troops of the Household Cavalry as they stood guard in central London in heavy ceremonial uniforms. Other guards reduced their duties. The capital’s Hyde Park, normally busy with walkers, was eerily quiet — except for the long lines to take a dip in the Serpentine lake.

“I’m going to my office because it is nice and cool,” said geologist Tom Elliott, 31, after taking a swim. “I’m cycling around instead of taking the Tube.’’

Queen Elizabeth II carried on working. The 96-year-old monarch held a virtual audience with new U.S. ambassador Jane Hartley from the safety of inside Windsor Castle.

A huge chunk of England, from London in the south to Manchester and Leeds in the north, remained under the country’s first “red” warning for extreme heat Tuesday, meaning there is danger of death even for healthy people.

Such dangers could be seen in Britain and around Europe. At least six people were reported to have drowned across the U.K. in rivers, lakes and reservoirs while trying to cool off. Meanwhile, nearly 750 heat-related deaths have been reported in Spain and neighboring Portugal in the heat wave there.

The highest temperature previously recorded in Britain was 38.7 C (101.7 F), a record set in 2019. Tuesday’s reading was provisional, which means they are produced as near to real time as possible with final readings issued after data quality-control, the Met Office said.

Climate experts warn that global warming has increased the frequency of extreme weather events, with studies showing that the likelihood of temperatures in the U.K. reaching 40 C (104 F) is now 10 times higher than in the pre-industrial era.

The head of the U.N. weather agency expressed hope that the heat gripping Europe would serve as a “wake-up call” for governments to do more on climate change.

“I hope that also in democratic countries, these kind of events will have an impact on voting behavior,” World Meteorological Organization Secretary-General Petteri Taalas told reporters Tuesday in Geneva.

Combatting climate change head on is the only solution for Britain, said Professor Myles Allen, a climate scientist at the University of Oxford, because continually refurbishing the country’s infrastructure to cope will be “extremely expensive.”

“We cannot afford to live in an ever-changing climate,” he told the BBC. “We have to stop this, turn this around.”

Drought and heat waves tied to climate change have also made wildfires harder to fight.

In the Gironde region of southwestern France, ferocious wildfires continued to spread through tinder-dry pines forests, frustrating firefighting efforts by more than 2,000 firefighters and water-bombing planes.

Tens of thousands of people have been evacuated from homes and summer vacation spots since the fires broke out July 12, Gironde authorities said.

A smaller third fire broke out late Monday in the Medoc wine region north of Bordeaux, further taxing firefighting resources. Five camping sites went up in flames in the Atlantic coast beach zone where blazes raged around the Arcachon maritime basin famous for its oysters and resorts.

But weather forecasts offered some consolation, with temperatures expected to ease along the Atlantic seaboard Tuesday and the possibility of rains rolling in late in the day.

Britain was not the only northern European country experiencing unusual heat. As Amsterdam baked Tuesday, municipal workers sprayed water on some mechanical bridges over the Dutch city’s canals to prevent metal in them from expanding, which can jam them shut blocking boat traffic. Temperatures in the city are expected to approach 39 C (102 F) on Tuesday.
