Projecting heat-related mortality impacts under a changing climate in the New York City region.

Objectives: We sought to project future impacts of climate change on summer heat-related premature deaths in the New York City metropolitan region.

Methods: Current and future climates were simulated over the northeastern United States with a global-to-regional climate modeling system. Summer heat-related premature deaths in the 1990s and 2050s were estimated by using a range of scenarios and approaches to modeling acclimatization (e.
