Last year was one of the seven warmest on record, the World Meteorological Organization (WMO), a United Nations agency, said on Wednesday.
Despite the cooling effect of La Niña between 2020 and 2022 on average global temperatures, 2021 remains one of the seven warmest years on record, according to six international datasets integrated by WMO. La Niña refers to a massive cooling of sea surface temperatures in the central and eastern equatorial Pacific Ocean. It has a temporary global cooling effect.
Last year’s global average temperature was 1.11 (±0.13) degrees Celsius above pre-industrial levels over the period from 1850 to 1900.
Last year was the seventh year in a row that average global temperatures was more than 1 degree Celsius above pre-industrial levels since 2015, a data set compiled by WMO shows.
The Copernicus Climate Change Service estimates that 2021 will be the fifth warmest year on record and slightly warmer than 2015 and 2018. The National Oceanic and Atmospheric Administration (NOAA) and Berkeley Earth found 2021 to be the sixth warmest year on record. NASA’s GISTEMP and HadCRUT also said 2021 is the sixth warmest year on record. Data from the Japan Meteorological Agency (JMA) Reanalysis Ranking 2021 shows that last year was indeed the seventh warmest year on record.
