Since so much of the ice sheet is grounded underwater, rising sea levels may have the effect of lifting the sheets, allowing more - and increasingly warmer - water underneath it, leading to further bottom melting, more ice shelf disintegration, accelerated glacial flow, and further sea level rise, and so on and on, another vicious cycle.
