Global Warming Science Speak: We aren't able to connect all the dots, but

Ancient ice shelf snaps and breaks free from the Canadian Arctic

Ancient ice shelf snaps and breaks free from the Canadian Arctic STEVE LILLEBUEN (CP) - A giant ice shelf the size of 11,000 football fields has snapped free from Canada's Arctic, leaving a trail of icy boulders floating in its wake.
The mass of ice broke clear from the coast of Ellesmere Island, about 800 kilometres south of the North Pole. Warwick Vincent of Laval University, who studies Arctic conditions, travelled to the newly formed ice island and couldn't believe what he saw. "It was extraordinary," Vincent said Thursday, adding that in 10 years of working in the region he has never seen such a dramatic loss of sea ice.

"This is a piece of Canadian geography that no longer exists."

The collapse was so powerful that earthquake monitors 250 kilometres away picked up tremors from it.

Scientists say it is the largest event of its kind in 30 years and point their fingers at climate change as a major contributing factor.

"We think this incident is consistent with global climate change," Vincent said, adding that the remaining ice shelves are 90 per cent smaller than when they were first discovered in 1906.

"We aren't able to connect all of the dots .?.?. but unusually warm temperatures definitely played a major role."
