Scientists say Europe's heatwave 'impossible' without climate change

scienceJun 26, 202642913

A World Weather Attribution study finds the current western Europe heatwave is the most severe and widespread ever and would have been impossible without human-driven climate change. The study says high humidity has pushed heat stress to record levels, with almost half of Europe’s 850 largest cities enduring their worst ever heat stress, a combination of temperature and humidity. Many capital cities recorded not only their hottest three-day period in June but their hottest three-day period at any time of year. The authors estimate that an event like this would have been about 2C cooler in 2003 and about 3.5C cooler in 1976 because of lower global heating then. Impacts are already acute: the UK set a new June temperature record, France shut down nuclear reactors, and heat-related deaths are rising in Spain, Italy and France. The London Ambulance Service reported its highest number of life-threatening emergencies in a single day driven by extreme heat. The study attributes the event to fossil fuel-driven warming and warns that without stopping emissions future heat conditions will become even more extreme.
