Globally, heat kills more people than any other weather-related event. With temperatures and humidity expected to increase in the coming decades, heat stress is projected to have increasingly severe impacts on many regions of the world. Here, researchers estimate the global exposure to fatal heat stress throughout the 21st century and its effects on human health, infrastructure, power generation, and economic performance.
