Sea Level, Ice, and Greenhouses -- FAQ
The stable configurations are for the ice sheet to advance all the way to the edge of the continental shelf, or to collapse to include no ice shelf. Why should we worry about the presence or absence of the ice shelves? They can't change sea level if they disappeared. But the ice shelves serve another role ...

NERC - Is the world's ice melting?
Antarctic ice sheet is growing or shrinking. They compare how much snow accumulates, with estimates of how much ice is lost as calving icebergs or through melting ice shelves. But this isn't very precise. Satellites can estimate how thick the ice sheet is by measuring the height of the ice surface ...
