UAH Global Temperature Update for December, 2021: +0.21 deg. C.
by Roy W. Spencer, Ph. D.
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for December, 2021 was +0.21 deg. C, up from the November, 2021 value of +0.08 deg. C.
The annual average anomaly for 2021 was +0.134 deg. C above the 30-year mean (1991-2020), which places it as the 8th warmest year in 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 over the global-averaged oceans, and +0.18 C/decade over global-averaged land).
Various regional LT departures from the 30-year (1991-2020) average for the last 24 months are:

As you're ROTFL at today's news that 2021 was a Top 10 'hottest year' (an imperceptible 0.134C warmer than the the 30-year average), remember to thank God for the fossil fuels that are keeping you warm and alive in the bitter cold reality outside. pic.twitter.com/Mb9d5gBZmu

Meteorologist Dr. Ryan Maue: “Remove abrupt forced cooling from Mount Pinatubo and your eyeball may discern a 25-year pause/hiatus or period of very slow global warming. Then El Niño of 2015 arrives and global temperatures skyrocket by +0.5°C.”

Strat warming and very cold early 2021 shows up well, too. pic.twitter.com/60ILcB5DKI
