Arctic ice shelf disappearing....

Huge chunk snaps off storied Arctic ice shelf

A four-square-kilometre chunk has broken off Ward Hunt Ice Shelf - the largest remaining ice shelf in the Arctic - threatening the future of the giant frozen mass that northern explorers have used for years as the starting point for their treks.

Scientists say the break, the largest on record since 2005, is the latest indication that climate change is forcing the drastic reshaping of the Arctic coastline, where 9,000 square kilometres of ice have been whittled down to less than 1,000 over the past century, and are only showing signs of decreasing further....

"The take-home message for me is that these ice shelves are not regenerating," he said. "If we're looking at an indicator of whether climate is to blame, it's really the lack of regeneration that convinces me. They're breaking away so rapidly that there's no hope of regeneration," he said, adding that is "pretty strong evidence that suggests this is related to global warming."
Stephen Harper's comments - "Pass me an ice cube for my scotch. Now what's the problem?"
