Graph: The New Normal in the US – Earth is Getting Hotter

by
Climate Central

NOAA publishes climatological normals every decade based on 30-year average temperatures; the most recent normals are based on the average temperatures from 1981-2010. Expanding on this dataset, Climate Central calculated a 30-year average ending each year from 1980 to 2015. For example, the normal temperature for 1980 in this analysis was based on the average temperature from 1951-1980, and the 2015 normal is the average from 1986-2015.

Of the 135 locations analyzed, 97 percent of them had a higher 30-year average temperature in 2015 versus 1980, and many have seen an additional surge in their normals since the last NOAA analysis in 1981-2010.
