2020 More Extreme Heat
Extreme heat looks much different today than just fifty years ago. Of the 242 cities analyzed, 142 (59%) experience three or more additional days of extreme heat. The ten cities recording the greatest increases in the number of extremely hot days were all in the southern United States ー seven of which were recorded in Texas alone.
NASA and NOAA recently announced that 2020 year-to-date global temperatures are the 2nd-hottest on record, just behind 2016. Greenhouse gas emissions are changing the atmosphere, causing our climate to warm to a level that modern society has never experienced.
Extreme heat is dangerous. It’s the top weather killer and is especially difficult to shelter from this year, as a result of the pandemic. The heat poses the most serious risks to outdoor workers and lower-income communities.
