West Antarctica Ice Shelves Collapsing

2009Antarctica

“Along the 900-mile (1450 km) peninsula that just north toward South America, interlocking temperature records, estimated from ice cores, ocean sediments, penguin rookery surveys, and thermometer readings show a very steep temperature increase over the last fifty years. The U.S. National Snow and Ice Data Center believe that the breakup since 1974 of seven peninsula ice shelves, comprising 5,200 square miles (13,500 sq. km) of ice, is due to this warming.”
