Iceberg Twice the Size of Manhattan Breaks Off Glacier in Greenland

"A huge iceberg that's about twice the size of Manhattan has broken off the Petermann Glacier in Greenland — the same sheet of ice that just two years ago "calved" another massive berg."

"'It's dramatic. It's disturbing,' University of Delaware professor Andreas Muenchow, tells The Associated Press. 'We have data for 150 years and we see changes that we have not seen before. ... It's one of the manifestations that Greenland is changing very fast.'"

"Satellite images taken by NASA on Monday and Tuesday confirm the news. We've taken three to show the break. Look to the area inside the small squares we've drawn on the images."
