Evolution Of The Antarctic Ice Sheet And How It Resists Climate Change

A new analysis of the stability of the Antarctic ice sheet shows that ice rises (pinning points that keep the floating parts of ice sheets in place) are formed during the transition between glacial and interglacial periods, which significantly slows down t ...
