Scientists from Cornell University and the Center for Scientific Studies in Chile report that glaciers in Patagonia are melting at an unprecedented rate. With the help of NASA, the team used satellite data to map the changes in the Southern Patagonia Icefields. They discovered that the melting is occuring at much higher elevations, where the ice is typically the coldest. The melting glaciers have released enough moisture to cover the entire continental US with one inch of water. Read more here.
