About this series

GISTEMP v4, NASA Goddard Institute for Space Studies, global land-ocean temperature index, annual mean (January–December), 1880–. Only complete years.

Indicator definition

Difference between the year’s global mean surface temperature and the 1951–1980 average, in °C. Land stations (GHCN) plus sea surface temperatures (ERSST). For a longer record on another baseline see Global temperature anomaly since 1850 (HadCRUT5).

How to read the data

Until about 1940 the anomaly stayed below zero (coldest: −0.48 °C in 1909). Since 1980 it has risen by about 0.2 °C per decade: 0.39 °C in 2000, 1.01 °C in 2020 and a record 1.28 °C in 2024. Single years move with El Niño and La Niña; look at decades.
