Global warming record. Global map of surface temperature anomalies for the period 1911 to 1915. This is part of a sequence showing the trend of global warming from 1880 to 2018. Recent years have seen the warmest years since modern records began in 1880. This map shows where Earth's surface was warmer or cooler in the daytime than the average temperatures. Red is warmer than average, white is normal, and blue is cooler than average. The maps use the Robinson projection and the NASA Goddard Institute for Space Studies (GISS) Surface Temperature Analysis dataset (GISTEMP).
