Killer Heat Wave

The video explains heat waves as a form of extreme weather that rapidly increases temperatures, leaving little time for adaptation. It describes how heat waves form when a high-pressure air mass becomes stationary, either over arid regions or warm waters, affecting moisture levels. Heat waves are common in North America and are more deadly than other extreme weather events. The 1995 Chicago heat wave is highlighted, where a mass of warm, moist air from the Gulf of Mexico caused high humidity and temperatures, resulting in 525 deaths over five days.
