NASA Study: More Greenland Ice Lost Than Previously Estimated
2024年1月17日 · Icebergs have tumbled from Greenland’s glaciers for thousands of years as part of a natural cycle that typically balanced glacier growth in the winter with melting and retreat in the summer. The new study finds that ice retreat has far outpaced growth throughout the …
Ice Sheets Today - National Snow and Ice Data Center
2024年8月14日 · 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.
Greenland Is Disappearing Quickly, and Scientists Have Found a …

Greenland Ice Sheet - NOAA Arctic
On 26 June 2023, Summit Station reached a temperature of 0.4°C and experienced melt for only the fifth time in its 34-year observational history. Introduction. The Greenland Ice Sheet (GrIS) is the second-largest contributor of sea-level rise (SLR), after thermal expansion (Zemp et al. 2019).
NASA scientists surprised by pace of Greenland glacier ice melt
2024年1月18日 · The study published in the journal Nature found the ice shelf, which makes up 80 per cent of the surface of Greenland, lost an additional 1,034 gigatonnes of mass between 1985 and 2022.
Greenland’s Ice Sheet May Be Losing 20% More Ice Than …
2024年1月17日 · Now, a new study reveals that about 20 percent more of the Greenland ice sheet has disappeared than previous estimates show. The missing ice has been breaking and melting from the ends of...
Greenland Ice Sheet - NOAA Arctic
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).
