Antarctic Ice Sheets (IMAGE) Princeton University Caption In two recent papers, Princeton University researchers present a probabilistic assessment of the Antarctic contribution to 21st-century sea-level change. Their methodology provides a consistent means to integrate the potential contribution of continental ice sheets such as Greenland and Antarctica into sea-level rise projections. In existing projections, the contribution of Antarctica to future sea-level rise is almost entirely derived from locations where present-day mass loss is concentrated (area 15, above). This is despite evidence that future discharge in other drainage basins -- which comprise more than 96 percent of the ice sheet's area -- remains uncertain.
