The consensus says that as a whole the Antarctic ice sheet is melting. Part of the issue is that the southern continent is not reacting to climate change uniformly, with some areas growing and others shrinking. The entire Antarctic ice sheet is about the size of the U.S. and Mexico combined.
NASA chief scientist Waleed Abdalati, one of the few top ice researchers who wasn’t part of the study, praised the work.
“Understanding how and why the ice sheets are changing today better equips us for understanding and predicting how much and in what ways they will change in the future,” he said.
