The Greenland Ice Sheet has been losing ice mass for the 30th consecutive year, with a significant loss of 173 Gt in 2025/26.

The traditional state of the Greenland Ice Sheet, at @carbonbrief, written by @Ruth_Mottram and myself and this year augmented by Antarctic data, is out! The Greenland Ice Sheet shrinks for the 30ᵗʰ year in a row. Based on a mixture of observations and model data, the loss in 2025/26 was 173 Gt (=173 km³). The average of three different models gives a loss of 135 Gt. In either case, the last year with an ice gain was 1995/96. On a longer perspective, Greenland and Antarctica together lost 11309 Gt of ice between 1979 and 2023. This has raised the global sea level by around 32mm, 19 mm from Greenland and 13mm from Antarctica. This distribution in contribution to sea-level rise will change in the future, as the Antarctic Ice Sheet is roughly 10 times larger than the Greenland Ice Sheet. Ice loss in Antarctica is dominated by marine-terminating glaciers, mainly in West Antarctica, the stability of which is hard to predict. https://www.carbonbrief.org/guest-post-greenland-ice-sheet-shrinks-for-30th-year-in-a-row
