A recent scientific analysis estimates that approximately 2,300 people died from heat-related causes across 12 major European cities during a severe heatwave that lasted from June 23 to July 2, 2025. The study, conducted by research teams from institutions including Imperial College London and the London School of Hygiene & Tropical Medicine, highlights that human-induced climate change contributed directly to about 1,500 of these deaths. During this period, average summer temperatures in affected areas rose by around 4°C (7.2°F), with cities such as Barcelona, Madrid, London, Milan, Paris, and Lisbon experiencing temperatures exceeding 40°C. The heatwave also coincided with widespread wildfires in France and Spain. June 2025 was recorded as the third hottest June globally and the warmest June ever for Western Europe. Scientists warn that many heat-related deaths are not officially reported, suggesting the actual toll could be higher. This event underscores the growing impact of climate change on extreme weather events and public health in Europe.
