If global warming some day causes the West Antarctic Ice Sheet to collapse, as many experts believe it could, the resulting sea level rise in much of the United States and other parts of the world would be significantly higher than is currently projected, a new study concludes. This is because current estimations do not consider several key forces, such as gravity, changes in the Earth's rotation or a rebound of the land on which the massive glacier now rests, scientists say in the new study.
