A blistering heat wave swept across Europe this week, shattering temperature records in multiple countries and claiming hundreds of lives as extreme heat warnings blanketed the continent from Ireland to Slovenia.
France endured its hottest night on record Wednesday, with the national average reaching 38.5°C (101°F). That same day, the country set a new daytime record of 30°C (86°F), then saw it eclipsed within hours. The town of Palluau in western France recorded 43.8°C (110.84°F), the highest temperature ever documented in the country.
The United Kingdom also shattered its June temperature record for the second consecutive day, with 36.7°C (98.06°F) recorded in Somerset on Wednesday. Other weather stations across the country exceeded the previous June record of 35.6°C, which had stood since 1957.
The human toll has been severe. Spain reported at least 212 heat-related deaths, while Italy recorded five. France documented 40 drowning deaths tied to unsupervised swimming as people sought relief from the punishing temperatures. Officials warned that large swaths of the continent faced heightened wildfire danger as drought conditions intensified.
The World Meteorological Organization cautioned that the heat wave would spread across Western, Central, and Southern Europe over the coming two weeks, threatening millions more.
A new World Weather Attribution analysis reveals how profoundly the climate has shifted. The researchers found that human-caused climate change made this week's extreme heat "virtually impossible" just 50 years ago. Had this June's heat wave occurred in the climate of 1976, daytime temperatures would have been roughly 3.5°C cooler.
The statistical fingerprints of warming are stark. Sweltering overnight temperatures keeping people awake are now about 100 times more likely than they were 23 years ago during the infamous 2003 European heat wave. Daytime peaks are roughly 10 times more likely. Nearly 45% of cities analyzed across 30 European countries have already broken or are predicted to break their highest ever heat stress levels.
Scientists compared weather observations and climate models from different eras to isolate the impact of human emissions. The El Niño-Southern Oscillation, a natural climate pattern, played no role in triggering this week's extreme temperatures, researchers found.
Theodore Keeping, an extreme weather and wildfire researcher at Imperial College London, said the connection between human activity and intensifying heat is undeniable. "The science of how climate change is worsening heatwaves is settled," he stated. "Continued fossil-fuel emissions are directly responsible for the disruption people are experiencing this week in their homes, schools and workplaces. The speed of change is startling. Every few years we are seeing heat records shattered in Europe."
Author James Rodriguez: "This heat wave wasn't just bad luck or a natural cycle, it's a direct consequence of choices we're making right now, and the data proves it."
