Scientists thickened Arctic ice with seawater, but there is a big catch

Scientists tested spraying seawater onto Arctic ice, which showed promising initial results. The treated ice became thicker and more reflective, resisting summer melting effectively. This method offers an alternative to controversial geoengineering approaches for ice preservation. While promising, researchers note significant challenges for large-scale implementation across the Arctic. Further work is essential before this technique can be considered for broader application.
