Earth's global surface temperatures in 2018 were the fourth warmest since 1880, an independent analysis by NASA and the National Oceanic and Atmospheric Administration (NOAA) has found. According to scientists at NASA's Goddard Institute for Space Studies (GISS) here, global temperatures in 2018 were 0.83 degrees Celsius warmer than 1951 to 1980 mean. NOAA's analysis found 2018 global temperatures were 0.79 degrees Celsius above the 20th-century average. Since the 1880s, the average global surface temperature has risen about one degree Celsius. NASA's temperature analyses incorporate surface temperature measurements from 6,300 weather stations, ship- and buoy-based observations of sea surface temperatures, and temperature measurements from Antarctic research stations.
