Europe is experiencing a severe summer marked by rolling heatwaves, drought, and wildfires, leading to widespread impacts including deadly temperatures, water shortages, and rising energy prices. The heatwaves are increasingly affecting the continent's nuclear power supply, with nuclear plants being taken offline due to high temperatures and warm rivers, a situation expected to worsen in coming decades. In Greece, gale-force winds have intensified wildfires near Athens, particularly in the towns of Keratea and Palaia Fokaia, resulting in the death of at least one elderly man and the destruction of homes and farmlands. Over 50 agricultural and forest fires have broken out in Greece in the past two days, marking one of the worst wildfire periods this summer. Firefighting efforts involve more than 200 firefighters, 11 water bombers, and seven helicopters. The wildfires and heatwaves are also affecting other parts of Europe, including Italy, where Mount Vesuvius has been closed to tourists, and France, where vineyards have been damaged. The combination of extreme weather and energy challenges is increasing gas consumption just as Europe prepares for winter amid geopolitical tensions involving the United States and Russia.
