Most Antarctic ice shelves are set to disappear if greenhouse-gas emissions remain high

The time points beyond which individual Antarctic ice shelves could no longer exist in their current form have been estimated under several anthropogenic emission scenarios. These projections take into account uncertainties related to ice, atmosphere and ocean processes, including those concerning poorly understood processes such as ice fracturing and iceberg formation. The disappearance of many Antarctic ice shelves could lead to a sea-level rise of 10 metres.
