Global Average Surface Temperature Anomalies

JMA monitors the long-term change of the global average surface temperature anomalies for the purpose of monitoring the global warming. In this page, the long-term changes of annual and monthly anomalies of the global average surface temperature are shown.

[Data and Analysis Method]

Annual Anomalies of Global Average Surface Temperature (1891 - 2023)

Select the Period --»

The annual anomaly of the global average surface temperature in 2023 (i.e. the average of the near-surface air temperature over land and the SST) was +0.54°C above the 1991-2020 average (+1.09°C above the 20th century average), and was the warmest since 1891. On a longer time scale, global average surface temperatures have risen at a rate of about 0.76°C per century.
