Ice Sheets Today - National Snow and Ice Data Center
Nov 19, 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.

NASA Study: More Greenland Ice Lost Than Previously Estimated
Jan 17, 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.
Greenland Ice Sheet - NOAA Arctic
The Greenland ice sheet covers ~1.63 million km 2 and contains ice equivalent to 7.4 m of eustatic sea level rise (Morlighem et al. 2017). Following decades of relative stability, the ice sheet has now lost mass almost every year since 1998, with tied years of record ice loss in 2012 and 2019 (Mankoff et al. 2021).
