A graph and an animated time series showing the change in global surface temperature relative to 1951-1980 average temperatures. The year 2023 is the warmest on record.

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 2024 was the warmest on record since recordkeeping began in 1880 (source: NASA/GISS ).

This color-coded map shows a progression of changing global surface temperatures since 1884. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.

Color-coded map of changing global surface temperature anomalies from 1880 through 2022.

Earth’s average surface temperature in 2023 was the warmest on record, according to an analysis by NASA.

Graphs showing ocean heat content change from 1955 to present, based on observations from satellites and various ocean measurement devices.
