NASA Publishes Global Temperature Data for 2025, Finds Slight Warmth Compared to 2023
According to a recent analysis by NASA scientists, the global surface temperature in 2025 was slightly warmer than in 2023, but within a narrow margin of error. The two years are effectively tied, with 2024 still holding the record as the warmest year on record since the temperature records began in 1880.
The dataset analyzed by NASA includes temperature data from over 25,000 weather stations worldwide, as well as readings from onboard ships and buoys that measure surface ocean temperatures, and research stations at Antarctica. The analysis took into account factors such as changing station locations and urban heat island effects to provide a more accurate picture of global temperature trends.
Other independent analyses by reputable organizations, including NOAA, Berkeley Earth, the Hadley Centre, and the European Copernicus Climate Services Network, have also confirmed that 2025 was the third-warmest year globally. These studies used similar data sets but applied different methodologies and models, yet all showed a consistent trend of continued global warming.
The complete set of NASA's global temperature data for surface temperatures is now available online. For more information on NASA's Earth Science programs, visit [www.nasa.gov/earth](http://www.nasa.gov/earth).
