What's New

NASA/GISS writes on their web page (https://data.giss.nasa.gov/gistemp/), "March 11, 2020: Dr. Joel Susskind from NASA/GSFC and his team created Surface Temperature Anomaly estimates from Remote Sensed data (Susskind et al. 2019). These estimates are completely independent from the data used by the GISS analysis." Below are the maps of comparison of these two different data sets for the longest period available.

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 lso available in data) and over ocean (data) are available. (Data through February 2020. last updated 2020/03/11, now with GHCN v4 and ERSST v5. For Nino 3.4 SST see El Nino/La Nina page (last modified 2020/03/04) for data source and more information.

We take the 1880-1920 global mean temperature as our best estimate for the pre-industrial value. However, the spatial coverage of stations is not good for that period (no Antarctica data, e.g.), so for the global maps we use 1951-1980 as the base period. Some other groups keep advancing their 30-year base period each decade, so that it is now 1981-2010. The above maps show the temperature change between these periods.
