Giant 'sandbanks' on the sea floor may be able to help protect glaciers from the effects of global warming. If they work as planned, these large walls could make glaciers last as much as 10 times longer than they otherwise would, researchers say.Simulations found they may even be able to recover from existing damage relatively quickly.Scroll down for video  The Thwaites glacier (pictured) is one of two fast-moving glaciers at the Western edge of the Antarctic ice sheet.
