2021: 6th warmest year on record
14 January 2022
Two U.S. science agencies — NASA and the National Oceanic and Atmospheric Administration — and a private measuring group released their calculations for last year’s global temperature on Thursday, and all said it wasn’t far behind ultra-hot 2016 and 2020.
Six different calculations found 2021 was between the fifth and seventh hottest year since the late 1800s. NASA said 2021 tied with 2018 for sixth warmest, while NOAA puts last year in sixth place by itself.
Scientists say a La Nina — natural cooling of parts of the central Pacific that changes weather patterns globally and brings chilly deep ocean water to the surface — dampened global temperatures just as its flip side, El Nino, boosted them in 2016.
Still, they said 2021 was the hottest La Nina year on record and that the year did not represent a cooling off of human-caused climate change but provided more of the same heat.
