Spatial distribution of global surface temperature anomalies for December 2021

December 2021

The monthly global mean surface temperature anomaly in December 2021 (i.e. the average of the near-surface air temperature over the land and the SST) was +0.25°C above the 1991-2020 average (+0.80 °C above the 20th century average). ), Y it was the third warmest since 1891. On a longer time scale, global average surface temperatures have been increasing at a rate of about 0.75°C per century.

Monthly global average surface temperature anomalies in December (1891 – 2021, preliminary value)

The five warmest years (for their anomalies in December)
1. 2015 (+0,61°C),
2. 2019 (+0,48°C),
3. 2021, 2018(+0.25°C),
5. 2014 (+0,24 °C)

Behavior of 2021: the sixth warmest

JMA monitors the long-term change of global average surface temperature anomalies for the purpose of monitoring global warming. This page shows long-term changes in annual and monthly global mean surface temperature anomalies.

Spatial distribution of global surface temperature anomalies for 2021

The annual global mean surface temperature anomaly in 2021 (i.e., mean near-surface air temperature over land and SST) was +0.22°C above the 1991-2020 average (+0.77 °C above the 20th century average), and it was the sixth warmest since 1891. On a longer time scale, global average surface temperatures have been increasing at a rate of about 0.73°C per century.
