With 1880-1920 Base Period

In this graph the base period is switched from our traditional 1951-1980 to 1880-1920 for the reasons given in "A Better Graph", but of course we continue to also produce our graphs with the 1951-1980 base period, as shown below. Data through January 2024 are used for computing the means. Figures in PDF. last modified 2024/02/08, now with GHCN v4 and ERSST v5.)

With Our Traditional 1951-1980 Base Period from Here

Below are maps of the mean surface temperature anomaly for the past month, the past three months, and the past 12 months. Regional weather patterns, apparent on the monthly time scale, tend to disappear in averages over longer time scales.
