A new report from World Weather Attribution (WWA) has declared that Europe's latest heat wave, which triggered red alerts across several countries, is the most severe ever recorded in the region. The study, released on Friday, attributes the extreme temperatures to fossil fuel-driven climate change, stating that such heat has been made significantly more likely and intense.
Unprecedented Temperatures Linked to Climate Change
The WWA analysis found that the temperatures experienced during this heat wave would have been virtually impossible 50 years ago. Even during previous record-breaking events, such as the 1976 heat wave, the 2026 temperatures would have been virtually impossible in June and highly unlikely at any time of the year. In 2003, the first major heat wave of this century, daytime heat like this would have been about 10 times less likely than today.
Nighttime temperatures recorded during this heat wave were even more extreme, being more than 100 times less likely in 2003. Many European capitals experienced their hottest three-day period in June and their hottest three-day spell since 1950, according to the report.
Rapid Warming of Western Europe
The report highlights that across large parts of Western Europe, June is warming faster than any other month. The hottest daytime temperatures are now warming at around three times the global average rate, while nighttime temperatures are warming at about twice the global average. The researchers warn that such extremes are becoming increasingly common as the climate warms.
Call for Rapid Fossil Fuel Phase-out
WWA emphasizes that a rapid phase-out of fossil fuels is critical to avoid even higher temperatures and their consequences in the future. The report states, 'Extreme heat is already reaching the limits of our societies’ ability to cope.'
International Study Collaboration
The findings are based on a study by researchers from Sweden, Denmark, the United States, the Netherlands, Ireland, and the United Kingdom. They assessed how human-induced climate change affected the likelihood and intensity of the extreme heat across Western Europe, focusing on the three hottest days and nights in the most severely affected areas, as well as conditions in 19 European capitals.
