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 March 2012. last updated 2012/04/13, now with GHCN version 3) For Nino 3.4 SST see El Nino/La Nina page (last modified 2012/04/05) for data source and more information.
Annual and 5-year mean land surface temperature and SST graph is given in PDF. (2012/04/27)
