Monthly Analysis
Global-mean monthly-mean surface temperature anomalies with the base period 1951-1980. V denotes the major volcanic eruptions, and m and M denote the years of the minima and maxima of sunspot number cycles, respectively. See a NOAA/NGDC page. Figure also available in PDF. (Updated on 2025/01/10) , now with GHCN v4 and ERSST v5.)
