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.

The animation above shows the change in global surface temperatures. Dark blue shows areas cooler than average. Dark red shows areas warmer than average. To smooth out variations due to short-term temperature changes (which are considered “noise” in the data), this map shows a 5-year running average.
The “Global Temperature” value on the home page dashboard shows global temperature change since 1880, compared to NASA’s 1951-1980 baseline.
