Nearly two-thirds of the excess deaths would not have happened without climate change, a study says.
Heat killed an estimated 50,000 people in European cities this summer, a record, according to a modelling study led by Imperial College London.
The researchers said nearly two-thirds of the excess deaths would not have occurred without climate change. The study covered 854 cities in 30 countries.
A separate economic analysis estimated the heat cost the EU about 0.17 per cent of GDP between April and September, roughly 17 billion euros, about 2.5 times the average of the previous decade.
Western Europe's summer averaged nearly 3 degrees Celsius above normal, with some days up to 12 degrees hotter. Heat deaths in 2022 and 2003 were estimated at about 29,000 and 28,000.
