Antarctic Ice Shelves

A study published in Science shows that the rate of melting in Antarctic ice shelves has increased from 25 cubic kilometers per year from 1994 to 2003 (6 cubic miles) to 310 cubic kilometers per year from 2003 to 2012 (74 cubic miles).  Ice shelves on the ocean hold back land ice.  Loss of the shelves allows glaciers to flow into the ocean and raise sea level.
