Global Temperature

LATEST MEASUREMENT:
LATEST ANNUAL AVERAGE ANOMALY:
2022 Created with Sketch.
An example of a temperature anomaly is how much warmer or colder than the long-term average a unit of time something is (like how much warmer than average the most recent year was globally).

Key Takeaway:

Earth’s global average surface temperature in 2020 statistically tied with 2016 as the hottest year on record, continuing a long-term warming trend due to human activities.

This graph shows the change in global surface temperature compared to the long-term average from 1951 to 1980. The year 2020 statistically tied with 2016 for the hottest year on record since recordkeeping began in 1880 (source: NASA/GISS). NASA’s analyses generally match independent analyses prepared by National Oceanic and Atmospheric Administration (NOAA) and other institutions.

The animation on the right shows the change in global surface temperatures. Dark blue shows areas cooler than average. Dark red shows areas warmer than average. Short-term variations are smoothed out using a 5-year running average to make trends more visible in this map.

The data shown are the latest available, updated annually.
