CNN —Evidence from a 2,000-foot-long ice core reveals that the West Antarctic Ice Sheet shrank suddenly and dramatically around 8,000 years ago, according to new research — providing an alarming insight into how quickly Antarctic ice could melt and send sea levels soaring.

The ice core analyzed in the study was drilled from Skytrain Ice Rise located at the edge of the ice sheet, near the point where the ice starts to float and become part of the Ronne Ice Shelf.
