Ice melt processes that take place at the ice–ocean boundary of Greenland and Antarctic glaciers play a pivotal role in their evolution and contribution to sea-level rise, but widespread observations in these regions are lacking. A major observational initiative will be necessary to drastically reduce uncertainties in projections and better prepare society for sea-level rise.
