A dramatic event has shocked the Arctic… and the scientists who study the area! A block of ice four times the size of Manhattan has split off from a Greenland glacier and they worry that another, even larger, is preparing to break off. A recent article in the NY Times drew such immediate interest that a hearing in Congress was held to address the issue – global warming and rising ocean temperatures.

Scale is always hard to judge in the treeless landscape of Greenland. The cliff walls visible in the photograph are roughly 3,000 feet high, or about three times as high as the Eiffel Tower.
