![]() "Record global temperature in 2020, despite a strong La Niña in recent months, reaffirms a global warming acceleration that is too large to be unforced noise – it implies an increased growth rate of the total global climate forcing and Earth’s energy imbalance.

The warming rate over land is about 2.5 times faster than over the ocean. The eight warmest years in the record occurred in the past eight years. "20 are tied for 6th warmest year in the instrumental record. "Global surface temperature in 2021 (see figure above) was +1.12☌ (~2☏) relative to the 1880-1920 average in the GISS (Goddard Institute for Space Studies) analysis. Annual temperature and ranking data are posted as a table by CSAS at Columbia University.ĬSAS Earth Institute annual update: January 13, 2022 It is the 5th warmest year on record since 1880. The global average temperature in 2022 was 1.16☌ warmer than the baseline average for 1880-1920. *Note: NOAA-NCEI reports temperature increases relative to the 20th Century global average surface temperature, not pre-industrial levels.
