Temperature-Related Impacts
Warmer average temperatures will lead to hotter days and more frequent and longer heat waves.[2] These changes will lead to an increase in heat-related deaths in the United States—reaching as much as thousands to tens of thousands of additional deaths each year by the end of the century during summer months. These deaths will not be offset by the smaller reduction in cold-related deaths projected in the winter months.[1] However, adaptive responses, such as wider use of air conditioning, are expected to reduce the projected increases in death from extreme heat.
