The troposphere (LT) temperature anomaly is +0.21 degrees below the global Version 6.0 global average for December 2021. C, up from +0.08 degrees of November 2021. C.
The average annual abnormality for 2021 is +0.134 degrees. C is above the 30-year average (1991-2020), making it the 8th warmest year on the 43-year satellite record, behind 2016, 2020, 1998, 2019, 2017,2010 and 2015.
The linear warming trend since January 1979 remains at +0.14 C/decade (+0.12 C/decade for the global average oceans and +0.18 C/decade). for land with a global average).
The regional LT departures that differ from the 30-year (1991-2020) average over the past 24 months are:
