    Global surface temperature

    Global surface temperature is the average temperature of Earth's surface. More precisely, it is the weighted average of the temperatures over the ocean and land. The former is also called sea surface temperature and the latter is called surface air temperature. Temperature data comes mainly from weather stations and satellites. To estimate data in the distant past, proxy data can be used for example from tree rings, corals, and ice cores. Observing the rising GST over time is one of the many lines of evidence supporting the scientific consensus on climate change, which is that human activities are causing climate change. Alternative terms for the same thing are global mean surface temperature or global average surface temperature. Series of reliable temperature measurements in some regions began in the 1850—1880 time frame. The longest-running temperature record is the Central England temperature data series, which starts in 1659. The longest-running quasi-global records start in 1850. Wikipedia

    (The global mean surface air temperature for that period was 14°C (57°F), with an uncertainty of several tenths of a degree.) The image below shows global temperature anomalies in 2022, which tied for the fifth warmest year on record. The past nine years have been the warmest years since modern recordkeeping began in 1880.
  3. Jan 10, 2025Lee esta nota de prensa en español aquí.. Earth's average surface temperature in 2024 was the warmest on record, according to an analysis led by NASA scientists.. Global temperatures in 2024 were 2.30 degrees Fahrenheit (1.28 degrees Celsius) above the agency's 20th-century baseline (1951-1980), which tops the record set in 2023.

    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).NASA's analysis generally matches independent analyses prepared by the National Oceanic and Atmospheric Administration (NOAA) and other research groups.
