Extreme Heat & Climate Change

No Image Description
Description
This tool shows the rapid increases in extreme heat projected to occur in locations across the US due to climate change. Results show the average number of days per year above a selected heat index, or “feels like” temperature, for three different time periods: historical, midcentury, and late century.

Note that data for the historical period reflect the annual average for all years between 1971 and 2000. For any given location, some years during that time period may have had more extreme heat days than reported here while others had fewer. Because extreme heat has increased since that historic period, places included in this tool may have experienced more frequent extreme heat in recent years than during the historic 30-year average.
