Witryna10 cze 2024 · NASA ICE Cryosphere Research Cryospheric Sciences at NASA Increases in ice loss from the glaciers of Antarctica, Greenland, and the rest of the Arctic are contributing to sea level rise, while similarly dramatic changes are occurring in the sea ice cover of the Arctic and Southern Oceans. Witryna30 kwi 2024 · The findings come from the Ice, Cloud and land Elevation Satellite 2 (ICESat-2), which was launched into orbit in fall 2024 and began taking detailed global elevation measurements, including over Earth’s frozen regions. By comparing the new data with measurements taken by the original ICESat from 2003 to 2009, researchers …
Climate of Antarctica - Wikipedia
WitrynaNearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt — around 30 × 106 km 3 (7.2 × 106 cu mi) of ice — the seas would rise by over 60 m (200 ft). [19] WitrynaThe Greenland Ice Sheet, the largest ice sheet of the Northern Hemisphere, holds enough water to raise global mean sea level by 7.4 meters, while the Antarctic Ice … team 5827
