Climatewatch: Antarctica

It seems Antarctic ice is finally catching up to the kind of loss rate experienced by the ice sheets of Greenland:
Escalating ice loss
Though not affected by direct temperatures increase as much as by warming ocean waters, it could have a more dramatic impact as a lot of the West Antarctic sheet is largely below sea level (as opposed to both Greenland and East Antarctic sheets, resting on rough mountainous terrain which slows down the ice flowing into the ocean). This could lead to much faster disintegration if a critical point is reached or the same phenomenon that happens with the Larsen B shelf occurs again.
