A review of the past six years of research on ice-sheet mass-balance change shows that accelerated loss from Greenland is a robust finding, but that loss from Antarctica is probably far lower than previously thought. In 2007, the Intergovernmental Panel
This work is an outcome of the ESA–NASA Ice Sheet Mass Balance Inter-comparison Exercise. A.S. was additionally supported by a Royal Society Wolfson Research Merit Award and by the ESA Climate Change Initiative. Reviewer information Nature thanks R. Bell and C. Hulbe for their contribution ...
2, and it is expected to continue to be so3. Although increases in glacier flow4,5,6and surface melting7,8,9have been driven by oceanic10,11,12and atmospheric13,14warming, the magnitude and trajectory of the ice sheet’s mass imbalance remain uncertain. Here we compare and...
The Antarctic Ice Sheet (AIS) has been losing ice mass and contributing to global sea level rise (GSLR). Given its mass that is enough to cause ~58 m of GSLR, accurate estimation of mass balance trend is critical for AIS mass loss monitoring and sea level rise forecasting. Here, we...
The Antarctic Ice Sheet(AIS)has been losing ice mass and contributing to the rise in the global sea-level(GSL)for the last 4 decades,as quantified by using satellite observations.We developed a framework for implementing the state-of-the-art input-output(IO)method that has the advantage of ...

Heat balance of West Antarctic ice streams, investigated with a numerical model of coupled ice sheet, ice stream, and ice shelf flow / Hulbe, C. (1998), Heat balance of West Antarctic ice streams, investigated with a numerical model of coupled ice sheet, ice stream, and ice shelf flow,...
Here we compare and combine 26 individual satellite measurements of changes in the ice sheet’s volume, flow and gravitational potential to produce a reconciled estimate of its mass balance. The ice sheet was close to a state of balance in the 1990s, but annual losses have risen since then,...
