Blog Post Image: ‘A better path’ toward projecting, planning for rising seas on a warmer Earth

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. (Image courtesy of Christopher Little)
