The Greenland Ice Sheet covers 84% of the island and the Antarctic Ice Sheet covers approximately 98% of the continent. Due to the significant thickness of these ice sheets, global warming analysis typically focuses on the loss of ice mass from the ice sheets increasing sea level rise, and not on a reduction in the surface area of the ice sheets. Nov 12, 2018 · The Greenland and Antarctic ice sheets under 1.5 °C global warming. Nature Clim Change 8, 1053–1061 (2018) doi:10.1038/s41558-018-0305-8. Download citation. Received. 15 March 2018. Accepted If it melted completely, the Greenland ice sheet—nearly the size of Mexico—would raise global sea level by around 23 feet (seven meters). 3,11 While the ice sheet is unlikely to disappear in our children's lifetimes, the pace of shrinking largely depends on what we do to limit future warming. 14 Apr 19, 2018 · Scientists are exploring changes underway in the Greenland Ice Sheet as a result of global warming. Aug 25, 2016 · Global warming is melting the Greenland Ice Sheet, fast The Greenland Ice Sheet is losing 110 million Olympic size swimming pools worth of water each year.
