This graph shows the change in global surface temperature compared to the long-term average from 1951 to 1980. Earth’s average surface temperature in 2023 was the warmest on record since recordkeeping began in 1880 (source: NASA/GISS). NASA’s analysis generally matches independent analyses prepared by the National Oceanic and Atmospheric Administration (NOAA) and other research groups. Overall, Earth was about 2.45 degrees Fahrenheit (or about 1.36 degrees Celsius) warmer in 2023 than in the late 19th-century (1850-1900) preindustrial average. The 10 most recent years are the warmest on record.
