Crevasses on Pine Island Glacier. It’s a process which, if it continues, could ultimately turn the West Antarctic ice sheet into an area of wide open ocean and raise global sea levels by 10 feet. There’s general agreement that these waters are responsible for West Antarctic retreat. The unavoidable question is what this sequence of events says about our own responsibility for destabilizing Pine Island (and, perhaps, other West Antarctic glaciers). And yet it’s hard not to wonder if whatever affected Pine Island during that era also affected its neighbors.
