| Description: | Net loss of ice from the Greenland Ice Sheet has occurred every year since the late 1990s (Mouginot et al. 2019; Mankoff et al. 2021), contributing to global sea level rise (see section 3f for details). Over the 2025 mass balance year (1 September 2024 to 31 August 2025), three independent estimates find that the ice sheet again lost mass, but at a rate ∼30% less than the 1991–2020 average of roughly −200 Gt annually. These estimates are from input–output (−146±72 Gt), gravity (−129±50 Gt), and elevation (−143±36 Gt) methods; the values agree within measurement uncertainties.The ice loss can be partitioned into ice discharge (iceberg calving) and surface mass balance (SMB). SMB is the sum of gain from snowfall and refrozen rainfall and loss from runoff, sublimation, and evaporation. Observations of air temperature, precipitation, snow cover, and albedo—key factors that influence SMB—over the 2025 mass balance year are summarized here.Air temperatures were generally higher than the 1991–2020 average, especially in northern Greenland (Fig. 5.20a). Autumn (September–November 2024) and winter (December–February 2024/25) temperatures were above average, and spring (March–May 2025) brought pronounced warmth across Greenland, with record monthly highs set at 6 out of 34 stations. Summer (June–August 2025) was slightly cooler than average, except in mid-August, when a heatwave raised temperatures, primarily along the west coast. |
