Antarctica's Largest Glacier Found to be 'Fundamentally Unstable' by New Study

Large-scale glacial melt is one of the realities that is being addressed by researchers in regards to global warming, as these systems of ice are the chief source of water contributing to sea level rise as global temperatures increase. There is a great deal of concern over the ice sheets covering Greenland, melting due to the nature of ocean currents in the region, and the ice shelves in West Antarctica, vulnerable from melt caused by warm water from below, as well as increasingly warm air from above. In contrast, the much more massive ice sheet that covers East Antarctica has historically been considered stable, and has been recorded as gaining ice in recent years, as opposed to the losses seen by Greenland and West Antarctica.
