Iceland’s Ok Glacier Melts Away
"These images show the latter stages of the decline of Okjökull, a melting glacier atop Ok volcano in west-central Iceland. (“Jökull” is Icelandic for “glacier.”) A 1901 geological map estimated that Okjökull spanned about 15 square miles (38 square kilometers). In 1978, aerial photography showed the glacier had shrunk to about 1 square mile (3 square kilometers). Today, less than half a square mile (less than 1 square kilometer) remains."
