January 2018 was the planet's fifth warmest January since record keeping began in 1880, said NOAA's National Centers for Environmental Information (NCEI) on Tuesday. NASA also rated January 2018 as the fifth warmest January on record, with the only warmer Januarys being 2016, 2017, 2007 and 2015. Global ocean temperatures during January 2018 were the fifth warmest on record, and global land temperatures were the eighth warmest on record. Global satellite-measured temperatures in January 2018 for the lowest 8 km of the atmosphere were the tenth warmest in the 40-year record, according to the University of Alabama Huntsville (UAH) and RSS.
