Prepare for Killer Heat

Since the 1960's the United States has been seeing a gradual rise in the number of days when the temperature reaches extreme levels. Locations across the country have witnessed more intense and longer lasting heat waves than in the past. A new report by the Union of Concerned Scientists, Killer Heat in the United States: Climate Choices and the Future of Dangerously Hot Days (2019), says that the number of days of extreme, dangerous heat are going to significantly increase even more during the 21st century.

In ‘Off-the-charts’ heat to affect millions in U.S. in coming decades National Geographic has used the study to map out which areas are going to see the highest increase in the number of days of extreme heat. The map is colored to show the predicted increase in the number of days per year which will experience dangerously high temperatures. The map shows that the Central Lowlands and Coastal & Staked Plains will see some of the biggest increases in extreme heat. These location won't necessarily see the most days of extreme heat, just the biggest increase of days of extreme heat. Florida and Texas will actually be among the most dangerous states to live. For at least five months of the year (on average) Florida and Texas will see the heat index exceeding 100 degrees Fahrenheit.

If you want to know how many days of extreme heat you can look forward to then you can explore the Union of Concerned Scientists' interactive map Killer Heat in the United States. This map shows how global heating will effect every county in the contiguous United States. It includes choropleth maps showing the predicted number of extreme days which can be expected in each county by 2050 and 2100. It visualizes the predicted number of days of extreme heat for four different heat index thresholds: above 90°F, above 100°F, above 105°F, and “off the charts.” (Off-the-charts days are so extreme they exceed the upper limits of the National Weather Service heat index scale)

Do you know a similar map for Europe? It would be useful because we also know heat records in France and in my Law Firmin Paris, I'm suffering from heat at this time.
