Scientists Link Europe's Record Heatwave to Climate Crisis

A new study by researchers from Sweden, Denmark, the United States, the Netherlands, Ireland, and the United Kingdom attributes Europe's current intense heatwave to a high-pressure system that has trapped warm air from North Africa over the continent. Temperatures in France, Germany, Italy, Spain, and southern England have soared 5 to 12 degrees Celsius above seasonal averages. The analysis reveals this heatwave as the most severe ever recorded in the region, noting that such daytime temperatures would have been "almost impossible" in 1976 and 10 times less likely during the major 2003 European heatwave, even without considering global warming.

Scientists calculated that without global warming, the current heatwave in Western Europe would have been substantially weaker, with daytime temperatures around 3.5 degrees Celsius lower under 1976 climate conditions and 2 degrees lower under 2003 conditions. Many European capitals are experiencing not only their hottest June on record but also their hottest three-day period in any month since 1950. Researchers also examined "wet-bulb globe temperature" (WBGT) measurements, which combine temperature and humidity to assess heat stress. According to this index, historical heat stress records have been broken or are expected to be broken in about 45% of European cities with populations over 50,000. High humidity exacerbates the danger by reducing the body's ability to cool through sweating.

The report highlights that the extreme heat affects not only human health but also ecosystems, energy infrastructure, and daily life. Media reports cited in the study indicate at least 40 heat-related deaths in France, leading to school closures, canceled outdoor events, and severe disruptions to rail transport. Emergency health calls in France increased by 20%. In the UK, some hospitals began prioritizing only life-threatening cases. Italy reported heat-related fatalities, power outages, and increased emergency service demand. Belgium and the Netherlands are also facing strain on their health and transportation systems. Researchers emphasize that heatwaves cause more deaths in Europe than all other natural disasters combined. An aging population, widespread chronic diseases, and unequal access to cooling facilities make societies increasingly vulnerable.
