History

Historical Context

Europe’s 2003 heat wave, which killed more than 70,000 people across France, Italy and Spain, spurred the EU to allocate €1.5 billion for climate-health projects and prompted WHO heat-risk guidelines for 30 states. The same pattern of extreme summer heat resurfaces in the Eastern U.S. heat dome of 2024, triggering National Weather Service warnings for Washington, New York and Philadelphia.
