Heat-Related Mortality in a Warming Climate: Projections for 12 U.S. Cities
Heat is among the deadliest weather-related phenomena in the United States, and the number of heat-related deaths may increase under a changing climate, particularly in urban areas. Regional adaptation planning is unfortunately often limited by the lack of quantitative information on potential futur...
