Projections of 21st-century sea-level fall along coastal Greenland.

ABSTRACT: The Greenland Ice Sheet will significantly contribute to global mean sea-level rise this century. However, glacial isostatic adjustment is expected to cause regional sea-level fall around Greenland as the land rebounds and the gravitational pull of the shrinking ice sheet decreases. A fall in local sea level has implications for Greenlandic communities whose economy, near-shore infrastructure, and food security are vulnerable to coastal changes, and for the dynamics of marine-terminating glaciers. In this study, we use a glacial isostatic model paired with sea-level and vertical land motion observations to predict future sea-level change in this region. We find that local sea level will fall around the island by 2100 CE (relative to 2017 CE) reaching a median value and likely range (17th-8
