January 2017 was Third-warmest January on Record
Scientists at NASA’s Goddard Institute for Space Studies (GISS) recently announced that January 2017 was the third warmest January on record since 1880, when the record for modern global temperatures began. January 2017 was 0.92° C warmer than the average January temperatures from 1951-1980.
The monthly analysis of global temperatures is compiled from publicly available data acquired by about 6,300 meteorological stations around the world, sea surface temperatures from thermometers on ship- and buoys, and Antarctic research stations.
The hottest January on record was 2016, which was 1.12° C warmer than the January mean temperature, followed by 2007 at 0.96° C warmer. January 2017 was third.
