“It’s no longer a question of if we will have a heatwave, but how many are we going to experience this year and how long will they last,” said Marisol Yglesias Gonzalez, technical officer for climate change and health at the WHO in Bonn.
As for how many people could be at risk, Pierre Masselot, a statistician at the London School of Hygiene and Tropical Medicine, told POLITICO this heatwave could cause more than 4,500 excess deaths between June 30 and July 3. The countries likely to experience the highest excess death rates are Italy, Croatia, Slovenia and Luxembourg, he said. “The worst days will likely be [Tuesday] and Wednesday.”
Heat claims more than 175,000 lives across the WHO’s Europe region — spanning from Iceland to Russia — each year. A major study co-authored by Masselot and published in January, which covered 854 European cities, warned that deaths from heat would rise sharply if significant climate adaptation is not prioritized.
The WHO on Monday echoed that climate change, driven by the burning of fossil fuels, means heatwaves will become more frequent, dangerous and intense, leading to more serious illness and death.
Almost two-thirds of Spanish towns have been slapped with health risk warnings, including 804 at the highest alert level, according to data from the Aemet national weather agency. A spokesperson stated that intense heat is expected across the country until July 3. Meanwhile, heat alerts are also in place in France, Italy, Portugal and Greece.
The Greek government has also issued warnings about air pollution from wildfires that have ripped through coastal towns near Athens. Meanwhile, more than 50,000 people have been evacuated in Turkey, primarily due to a fire near Izmir.
