The data is clear: Earth’s temperature is on the rise, with the 10 most recent years being the hottest on record. Extreme heat is the number one weather-related killer in the United States. Laws and policies to protect individuals from the health hazards of extreme heat exposure are being contemplated across the nation at the federal, state, and local level. This paper aims to address the realities of extreme heat exposure and community needs during extreme heat. First, it will define important terms relevant to heat as used in climate science, occupational health, public health, and other fields. Second, it will describe heat exposure and needed protections for vulnerable populations, such as communities located in urban heat islands, those experiencing direct heat exposure in the workplace and those who lack access to cooling equipment at home. Last, the paper will explore law and policy approaches to address the health impacts of extreme heat, including a focused discussion of two different areas of the country: Florida and New York City.
