The complex relationship between Antarctica’s glaciers and the land on which they rest may help slow the rate of ice loss in the long term, according to a new method for modeling such interactions. Scientists are confident that as the Earth warms, more of its ice sheets will melt, adding to rising sea levels. But how much and how quickly they will shed their water are big unknowns. The new study is part of world-wide efforts to decrease those uncertainties by gathering more detailed data and developing new analytical methods…
