Europe swelters under an early heat wave as France records 40 drowning deaths

PARIS (AP) — Millions of people across Europe were exposed to extreme and exceptional high temperatures on Tuesday, with 40 fatalities from drowning recorded in France in the past week as residents seek relief from the searing heat.

Temperatures will remain high around the clock in France, the European nation the most affected so far by the early summer heat wave. The national weather service, Meteo France, placed 54 departments, about half the country, under a red heat wave alert.

Italy, Spain, and Britain were also hit.

Human-caused climate change is tied to increasingly extreme weather, and U.N. climate agency projections say the next five years should shatter more heat records.

French Prime Minister Sébastien Lecornu said that the 40 people who died by drowning since last Thursday were mainly young people.

The Louvre and the Eiffel Tower are closing early

In a country without widespread air conditioning, schools, public transportation and sporting events have been impacted. In Paris, the Eiffel Tower adjusted its operations to the scorching weather, closing in the afternoon instead of late at night as it usually does. The Louvre museum said it would close two hours earlier than normal from Wednesday through Saturday.

"Although parts of its historic building are naturally resilient, the museum remains vulnerable and is not sufficiently adapted to climate change," it said. "Heat buildup is greatest toward the end of the day and is further intensified by high visitor numbers."

Extreme conditions are expected to last at least until the end of the week, with daytime highs above 40 degrees Celsius (104 degrees Fahrenheit) in many towns.

"Further record-breaking temperatures are expected, including some that could surpass all previous records, regardless of the time of year," Meteo France said.

The heat wave is exceptionally intense, coming very early in the summer, "but with a still uncertain duration," the weather service said. It has already been compared to the August 2003 heat wave, when the highest temperatures in over half a century caused an estimated 15,000 deaths, many of them among older people in apartments and retirement homes without air conditioning.

Europe is the world's fastest-warming continent, with temperatures increasing twice as fast as the global average since the 1980s, according to the European Union's Copernicus Climate Change Service. Over the last four years, more than 200,000 people across Europe died from heat-related causes, and most of those deaths were preventable, the World Health Organization's Europe office said this month.

The above-average temperatures can cause heat exhaustion and life-threatening heat stroke.

Heat wave hits Britain and Spain

Across the English Channel from France, many British schools said they were closing for the day and trains were disrupted as the Met Office, the U.K. weather agency, issued a red extreme heat warning for Wednesday and Thursday, with forecasts suggesting June's all-time daily temperature record could be broken.

Temperatures of around 37 degrees C (98.6 F) are expected in southern England, with up to 35 C (95 F) in southeast Wales. The peak of the heat wave is now forecast for Wednesday and Thursday, when highs could reach at least 39 C (102.2 F). Conditions are expected to ease by Friday, the Met Office said.
