Summary Figures

Monthly (thin lines) and 12-month running mean (thick lines or filled colors in case of Nino 3.4 Index) global land-ocean temperature anomaly, global land and sea surface temperature, and El Nino index. All have a base period 1951-1980. Figure also available in PDF. The monthly mean temperature anomalies over land (data) and over ocean (data) are available. (Data through October 2017. last updated 2017/11/16, now with GHCN version 3.3.0 and ERSST v5. For Nino 3.4 SST see El Nino/La Nina page (last modified 2017/11/04) for data source and more information.
Annual and 5-year mean land surface temperature and SST graph is given in PDF. (2017/01/18)

Recent surface temperature in different temporal resolution. PDF (Data through October 2017 used. Now with GHCN V3.3.0 and ERSST v5. Last updated: 2017/11/16.)

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.
