approximately 500 square miles of ice in the middle and about 30-80 on

part of Petermann Glacier reducing its volume by 10% and its area by
about 25%. Another important concern in recent years has become the
glacier’s melting.
In cooperation with the Greenpeace an expedition of three researchers
spent three months in Greenland exploring Petermann Glacier ant its
changes due to the global warming. They found a beautiful river created

was named Blue River and it attracts a great number of ...more
