Heat Wave

A heat wave is a prolonged period of abnormally hot weather. With an overall warming of the Earth’s climate, heat waves are expected to become more frequent, longer, and more intense in places where they already occur. Increased frequency and severity of heat waves can lead to more illness and death, particularly among older adults, the young, and other vulnerable groups.
