A collapse of the West Antarctic ice sheet is considered possible if not highly likely over the next few centuries, with potential to raise global sea level approximately 5 m, and larger sea-level rise possible if changes propagate into the East Antarctic ice sheet. Continuation of recent West...

Uncertainties in Representative Concentration Pathway (RCP) scenarios and Antarctic Ice Sheet (AIS) melt propagate into uncertainties in projected mean sea-level (MSL) changes and extreme sea-level (ESL) events. Here we quantify the impact of RCP scenarios and AIS contributions on 21st-century ESL...
Over the last two decades, the Greenland ice sheet (GrIS) has been losing mass at an increasing rate, enhancing its contribution to sea-level rise (SLR). The recent increases in ice loss appear to be due to changes in both the surface mass balance of the ice sheet and ice discharge (...

Using remote sensing satellites and ground-based meteorological observations, researchers have been able to study changes in surface meltwater. However, monitoring water hidden inside and beneath the ice sheet at high temporal and spatial resolutions has remained challenging, Ran explained. ...
Controversy about the amplitude and timing of this meltwater pulse (MWP-1A) has, however, led to uncertainty about the source of the melt water and its temporal and causal relationships with the abrupt climate changes of the deglaciation. Here we show that MWP-1A started no earlier than 14,...
