Monster iceberg on the loose

And whatever gets in its way is going to have a bad day:

An island of ice more than four times the size of Manhattan is drifting across the Arctic Ocean after breaking off from a glacier in Greenland. Potentially in the path of this unstoppable giant are oil platforms and shipping lanes - and any collision could do untold damage.

Few images can capture the world's climate fears like a 100-square- mile chunk of ice breaking off Greenland's vast ice sheet, a reservoir of freshwater that if it collapsed would raise global sea levels by a devastating 20 feet.



How much more of Greenland needs to melt before the Outer Banks disappear? (..not to mention the eventual plight of the one billion people who live along the vulnerable coastlines of the world...)
