The Cryosphere, September 17
Sea-level rise from the Greenland and Antarctic ice sheets alone could be 39 cm higher by 2100 than previously estimated under high emissions scenarios. These new estimates come from a large international effort comprising more than 30 different institutions and 60 leading ocean, climate and ice-sheet scientists; and are based on CMIP6, the newer models developed for IPCC AR6. The two papers – one focused on Greenland, the other on Antarctica — also show that ice loss and sea-level rise is much lower under low emissions scenarios consistent with 1.5°C, adding just 3-6 cm more to previous estimates under the new modeling, an 85% reduction.
