Alarming New Findings on Antarctic Melting and Climate Change

A new study published in the journal Nature shows that parts of a huge ice sheet covering Eurasia retreated up to 2,000 feet per day at the end of the last ice age, far outpacing the fastest-moving glaciers studied in Antarctica. The finding has sparked fears about how quickly ice in Greenland and Antarctica could melt and raise global sea levels in today's warming world. If air and ocean temperatures around Antarctica were to increase as projected, researchers say ice marching backward hundreds of feet in a day could trigger a collapse of modern-day glaciers sooner than previously thought.
