North America: 10th warmest As detailed in a January 12 post at this site by Bob Henson, 2020 for the U.S. was the fifth-warmest year in history going back to 1895. Ten states had their second-warmest year on record and four had their third-warmest year. None of the contiguous 48 states was below-average in temperature in 2020. Figure 1. Departure of temperature from average for 2020, the second-warmest year the globe has seen since record-keeping began in 1880, according to NOAA. Record-high annual temperatures over land and ocean surfaces were measured across parts of Europe, Asia, southern North America, South America, and across parts of the Atlantic, Indian, and Pacific oceans. No land or ocean areas were record cold for the year. (Image credit: NOAA National Centers for Environmental Information)
