Europe heatwave kills an estimated 50,000 people in urban areas

A study published in Nature Health by researchers from Imperial College London and the London School of Hygiene & Tropical Medicine estimates that extreme heat killed approximately 50,000 people in European urban centers during the summer of 2026. The analysis covered 854 urban areas across 30 countries, including the EU, UK, Norway, and Switzerland, representing about 40% of the population.

Researchers attribute approximately two-thirds of these deaths—roughly 32,000 fatalities—directly to human-caused climate change driven by fossil fuel combustion. This death toll is significantly higher than previous record years, such as 2022 (approximately 29,000 deaths) and 2003 (approximately 28,000 deaths).

The most lethal period occurred between June 17 and July 1, 2026, accounting for nearly one-third of all heat-related deaths. During this window, temperatures were on average 5 degrees Celsius above the 1991–2020 baseline. While the elderly were most affected, the study noted that approximately 6,000 deaths occurred in individuals under the age of 65.

Italy, France, Spain, Germany, and the United Kingdom recorded the highest absolute numbers of heat-related deaths. Experts warn that many European infrastructures are not designed to withstand such extreme temperatures, necessitating urgent adaptation and cooling strategies.
