Greenland glacier calves the Arctic's largest ice chunk in nearly a half-century

One of the largest of Greenland's marine "outlet" glaciers (i.e. glaciers ending in the sea) has calved an enormous "ice island" that reportedly extends over 100 square miles.  Not since 1962, when a 250 square mile island was formed from the Ward Hunt Ice Shelf, has such a large area of ice been calved in the Arctic.
