Interactive global land and ocean temperature anomalies maps, available at the NOAA Climate at a Glance website, provide valuable illustrative data. The anomalies are based on 1981-2010 mean.
Where do these data come from?
Global temperature anomaly data come from the Global Historical Climatology Network-Monthly (GHCN-M) data set and International Comprehensive Ocean-Atmosphere Data Set (ICOADS). A combined global land and ocean temperature anomaly dataset was created from these resources.
