   18 cze 2024 · Ice Sheets Today offers the latest satellite data and scientific analyses on surface melting of the Greenland Ice Sheet in the Northern Hemisphere and Antarctic Ice Sheet in the Southern Hemisphere. Surface melt on each ice sheet results from a combination of daily weather conditions and the amount of solar energy absorbed by its snow and ice.

   17 sty 2024 · From 1985 to 2022, as icebergs fell into the ocean at an accelerating rate, the Greenland Ice Sheet shed about 1,140 billion tons (1,034 billion metric tons) – one-fifth more mass than previously estimated.

   21 lis 2012 · The mass of ice in the Greenland Ice Sheet has begun to decline in recent decades, attended by an increase in surface melt. At high elevations on the ice sheet, an increase in winter snow accumulation has partially offset the melt.

   Ice sheets gain mass from net snow accumulation and lose mass through meltwater runoff and solid ice discharge. The sum of accumulation and runoff is termed surface mass balance (SMB) and is primarily responsive to air temperature, snow cover, albedo, and bare-ice area.

   Key Takeaway: Antarctica is losing ice mass (melting) at an average rate of about 150 billion tons per year, and Greenland is losing about 270 billion tons per year, adding to sea level rise. Data from NASA's GRACE and GRACE Follow-On satellites show that the land ice sheets in both Antarctica (upper chart) and Greenland (lower chart) have been ...

   During September 2022, the Greenland Ice Sheet experienced unprecedented late-season melt events, including surface melt conditions across 36% of the ice sheet surface on 3 September, including at Summit Station (3216 m above sea level in the ice sheet interior).
