The warmer the higher: Sea-level rise from Filchner-Ronne ice in Antarctica
The more ice is melted of the Antarctic Filchner-Ronne shelf, the more ice flows into the ocean and the more the region contributes to global sea-level rise. While this might seem obvious, it is no matter of course for the huge ice masses of Antarctica: parts of the ice continent are characterized by instabilities that, once triggered, can lead to persistent ice discharge into the ocean even without a further increase of warming - resulting in unstoppable long-term sea-level rise. In the Filchner-Ronne region however, ice-loss will likely not show such behavior, scientists from the Potsdam Institute for Climate Impact Research now found. Published in Nature Climate Change, their study shows that in this area the ice flow into the ocean increases just constantly with the heat provided by the ocean over time.
