France, the Netherlands and Belgium have recorded 3,700 excess ​deaths during the June heatwave that sent temperatures soaring ‌across Europe, with authorities warning that the numbers are preliminary and could rise.

Experts have said the heatwave, which lasted from about June ​20-28, was the worst recorded in Europe, causing disruption to ​power generation, damaging infrastructure and overwhelming healthcare systems. The ⁠extreme heat was almost certainly driven by climate change, scientists ​said, Reuters reported.

There were 2,025 excess deaths recorded in France during the ​heatwave, with a particular increase in deaths among people aged over 45, French Health Minister Stephanie Rist told local television on Friday.

Deaths at home ​rose 91% between June 22-28 compared to the previous ​week, while deaths in nursing homes and healthcare facilities also increased, the ‌country’s ⁠public health authority said in a bulletin.

“Mortality will … be higher than these initial figures suggest,” the authority warned.

‘UNPRECEDENTED’ MORTALITY DATA

In Belgium, the Health Ministry said on Thursday it had registered ​excess mortality of ​about 1,200 ⁠deaths between June 18 and June 29, adding that 530 of the deaths were among people ​aged 85 or older. People aged under ​65 accounted ⁠for 180 of the excess deaths.

“Such excess mortality during a heatwave is unprecedented in our country,” the ministry said in ⁠a statement.

Authorities ​in the Netherlands said the heatwave led ​to about 480 excess deaths, mainly among the over 80s.

Forty people have drowned in France over recent days as they sought to cool down to escape record ​heat, the prime minister said on Tuesday, as a heatwave swept across much of Europe.

Britain, Italy, Switzerland and Spain were also sweltering in extreme heat, with record temperatures ‌in some areas disrupting schools and transport networks and forcing tourist sites – including the Eiffel Tower – to shut.

Europe is warming at more than twice the global average, according to the World Meteorological Organization, making such prolonged heat episodes increasingly likely.

HEAT ALERT ACROSS FRANCE

France experienced its hottest day on record on Tuesday, Meteo France forecaster said, with a peak of 44.3 degrees Celsius (111.74 degrees Fahrenheit) in one town in the south west.

Fifty-four departments are under red alerts in what Meteo ​France said was unprecedented. That will jump to 58 on Wednesday.

Across the country, people have been jumping into canals and rivers to cool off. Sports minister Marina Ferrari said ​she understood the urge to escape the heat but warned against swimming in unauthorized or dangerous areas.

Speaking ahead of an emergency meeting on the ⁠heatwave, Prime Minister Sebastien Lecornu called the drownings “a sad scourge” and said there had been 40 deaths since June 18, most of them young people.

On Monday, first responders were unable to resuscitate ​two children, aged 2 and 4, who were found unconscious by their mother in the family car outside their home, said a prosecutor in Carpentras, southeast France.

HEAT DOME

The heatwave is being driven by ​a weather pattern known as an Omega block, because it takes the shape of the Greek letter Ω, with a bulge of hot air trapped between cooler systems, allowing temperatures to build day after day. Heatwaves and storms are being intensified by climate change.

Meteo France said current conditions were comparable to the August 2003 heatwave, which lasted 16 days and led to an estimated 80,000 excess deaths across Europe. It was uncertain how long the current episode would ​last.

“Thursday will once again be a sweltering day (in France), with temperatures remaining just as high. On Friday, a gradual drop is expected to begin from the Atlantic coast,” the weather forecaster said.

​Heatwaves can affect people’s physical and mental health but also force businesses to adapt and put grain harvests at risk.

HEAT ALERTS IN ITALY, BRITAIN

In Italy, the health ministry issued its highest level alert for 15 cities and authorities took ‌measures to curtail ⁠work in some sectors. Storms were expected over the Alps and Apennines, bringing heavy rain, gusty winds and hail.

Britain is also in the grip of the heat, with the Met Office forecasting temperatures of up to 37 C in southern England on Tuesday — potentially a new June record — before rising further on Wednesday and Thursday. Dozens of schools planned early closures.

Transport networks across Europe came under strain, with trains cancelled or running more slowly.

CLIMATE SHELTERS

Spain’s meteorological agency has issued red alerts across parts of the country, warning of dangerous heat with temperatures expected to reach 44 C. Dozens of municipalities ​across northern Spain cancelled traditional bonfires due to wildfire ​risks.

Madrid has opened climate shelters for the ⁠homeless and other vulnerable people.

In Belgium, soaring temperatures forced a primary school near Brussels to relocate its final exams to a nearby church.

In Switzerland, the northeastern canton of St. Gallen restricted water withdrawal from rivers and lakes, citing low levels and high temperatures.

TRYING TO ADAPT

In cities affected by the ​heatwave, fans and air conditioning units were flying off the shelves.

“I came quick, I haven’t even had my coffee this morning, I ran here ​to buy an electric ⁠fan,” said filmmaker Victoria Yakubov, who managed to snag one last remaining fan in a Paris shop. “Everything was gone in less than 30 minutes.”

It was the same story in London, with fans “flying off the shelves”, John Lewis Oxford street branch manager, Paul Marsden said.

As parts of Europe baked, and the Eiffel Tower closed at 4 p.m. (1400 GMT) because of the heat, cooler northern destinations were drawing tourists seeking a “coolcation”.

“We were thinking ⁠about travelling ​to Croatia, but we came to Sweden because it’s cooler here,” said German tourist Katharina Rexing in Stockholm’s Old Town, ​on a day when it was 22 C in the Swedish capital and 30 C in Croatia’s Zagreb.

The United ​Nations weather agency forecast on Tuesday a moderate or possibly a strong El Nino that could drive up global ‌temperatures and increase the risk of extreme weather over the coming months.

El Nino is a periodic warming of sea surface temperatures in the central and eastern Pacific Ocean, which typically lasts between nine and 12 months, according to the World Meteorological Organization.

The WMO said warm ocean waters were driving El Nino’s development and predicted ​above-average temperatures in most parts of the world from June to August. The WMO said it is likely El Nino ​will continue until November.

It also said it remained uncertain how strong El Nino will be as models ⁠differ on its severity, but officials warned of the need to be ready.

“We need to prepare for a potentially strong El Nino ​event – which will exacerbate drought and heavy rainfall and increase the risk of heatwaves both on land and in the ocean,” said ​WMO Secretary-General Celeste Saulo.

MORE DROUGHTS, HURRICANES AND HEAT?

The weather pattern is known to disrupt regional climates, potentially bringing warmer temperatures across the globe, while increasing rainfall to the southern parts of South America and the United States, parts of the Horn of Africa and central Asia.

El Nino can also cause drought in ​Australia, Central America, Indonesia, and parts of south Asia, and spur hurricane formation in the central and eastern Pacific, the WMO said.

The ​last El Nino, which meteorologists said was strong, in 2023 to 2024 contributed to making 2024 the hottest year on record, Saulo said.

Saulo said other ‌risks ⁠associated with extreme heat included a wider spread of diseases borne by vectors such as mosquitoes and ticks and reduced food and water supplies.

“Communities that were already struggling will be pushed farther beyond their limits,” she said.

For consumers, facing inflation because of the Iran war, food prices may rise further because of El Nino.

Hein Schumacher, CEO of Barry Callebaut, one of the world’s biggest cocoa processors, warned crops in ​the growing regions of Ecuador and ​West Africa that account for ⁠60% of global output could be reduced.

“This is something that we are very cautiously observing,” he told media on a call on Tuesday. “El Nino could have an effect that could lead to, you ​know, a few thousands per ton.”

London cocoa futures are trading at £2,944 ($3,964.10) per metric ton, down from more ​than 9,000 in ⁠April 2024.

Some national weather agencies have forecast the strongest El Nino in a decade.

The WMO is more circumspect but said it had observed unusually warm subsurface conditions across the tropical Pacific with temperatures exceeding 6 degrees Celsius (10.8 degrees Fahrenheit) above average, creating a reservoir of heat that is ⁠driving surface ​warming.

U.N. Secretary-General António Guterres said it was a reminder of the need for ​a shift away from fossil fuels towards renewable energy.

“The world must treat it as the urgent climate warning it is. El Nino conditions will pour fuel on the ​fire of a warming world,” he said.
