Last month saw the lowest global sea ice cover for any February on record in a stark reminder of how our planet is warming, new data reveal.
Sea ice is the frozen seawater that floats on the ocean's surface. As the planet warms, the amount of sea ice declines. In February 2025, sea ice around the poles reached an "all-time minimum" when compared with previous Februaries (records began in 1979), according to a statement from the European Union's Copernicus Climate Change Service.
