In a dramatic development, the giant rift in the Larsen C ice shelf has grown an additional 17km since last week, and the leading tip of the crack is now exceptionally close to the ocean. There's now very little to prevent a complete collapse -- an event that will produce one of the largest icebergs in recorded history.

This past summer (winter in Australia), a massive chunk of ice slipped away from a glacier in British Columbia, but no one was there to notice. Using satellite images, a scientist from NASA has now spotted the unusually large iceberg -- and he suspects it's the largest ever seen in North America.
