The year 2023 was the hottest year in NASA’s record, continuing a trend of warming global temperatures.

Our record is calculated from millions of measurements from thousands of weather stations, ships and ocean buoys, and Antarctic research stations. It uses data starting in 1880, when coverage made it possible to reliably estimate global temperature.

Despite 2023 being the globally hottest year, individual locations may not have experienced a record-warm year. However, the effects of our changing climate are felt around the globe, with record droughts, shifting fire seasons, and sudden, intense precipitation events.

With more than 20 spacecraft and thousands of researchers studying Earth systems and the impacts of rising global temperatures, we’re helping people prepare for life on Earth now and in the future. Next month, we’re launching a new satellite, PACE, to add yet another dimension to our view of Earth and the climate.
