A major satellite-based study has found that Greenland and Antarctica lost about 12.5 trillion tons of ice between 1979 and 2025, contributing more than 1.2 inches to global sea-level rise. Researchers from the IMBIE team analyzed 42 satellite surveys involving 27 missions to track changes over nearly five decades. About 84% of the ice loss occurred because glaciers accelerated into the ocean, rather than from surface melting alone, highlighting the influence of warmer ocean waters. Ice loss increased sharply from the 1990s, although temporary slowing between 2020 and 2023 was linked to snowfall and weather conditions.
