17 sty 2024 · 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 21st century.
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 · We found that Greenland has lost more than 1,000 gigatonnes (1 Gt is 10 9 tonnes) of ice owing to terminus retreat alone since 1985 (Fig. 1), representing an extra 20% loss that has not been ...
17 sty 2024 · 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...
18 sty 2024 · 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.
7 lis 2023 · Scientists analyzed eight ice shelves buttressing glaciers in northern Greenland, which together hold enough ice to raise sea levels by 2.1 meters — nearly 7 feet — should they break down and...
18 paź 2023 · Greenland holds enough ice to raise global sea levels by 7 metres if it were all to melt. The sheet currently loses around 270 billion tonnes of ice each year, and contributes a substantial...
