Mapping the Vulnerability of Urban Populations to Extreme Heat Events Challenge The frequency and intensity of extreme heat events have been increasing globally and are projected to continue increasing through the 21st century. Compounding the rising average and extreme temperatures that are occurring with climate change, urban heat islands (UHIs) can add 6 to 8° C to urban temperatures compared to rural locations for many mid-latitude cities. UHIs can result from excess heat absorbed by built infrastructure, high vehicle emissions, and a lack of cooling. Extreme heat, which is exacerbated by the UHI effect and climate change, is the leading cause of weather-related mortality in the United States and many other countries. The large populations concentrated in urban areas and their high deg
