Annual Anomalies of Global Average Surface Temperature (1891 - 2013)


Select the Period --»

The annual anomaly of the global average surface temperature in 2013 (i.e. the average of the near-surface air temperature over land and the SST) was +0.20°C above the 1981-2010 average (+0.57°C above the 20th century average), and was the 2nd warmest since 1891. On a longer time scale, global average surface temperatures have risen at a rate of about 0.69°C per century.
