Ice Mass Snaps Free From Canada's Arctic
TORONTO (AP) -- A giant ice shelf the size of 11,000 football fields has snapped free from Canada's Arctic, scientists said. The mass of ice broke clear 16 months ago from the coast of Ellesmere Island, about 497 miles south of the North Pole, but no one was present to see it in Canada's remote north. Scientists using satellite images later noticed that it became a newly formed ice island in just an hour and left a trail of icy boulders floating in its wake.
Warwick Vincent of Laval University, who studies Arctic conditions, traveled to the newly formed ice island and could not believe what he saw.
''This is a dramatic and disturbing event. It shows that we are loosing remarkable features of the Canadian North that have been in place for many thousands of years. We are crossing climate thresholds, and these may signal the onset of accelerated change ahead,'' Vincent said Thursday.
In 10 years of working in the region he has never seen such a dramatic loss of sea ice, he said.
The collapse was so powerful that earthquake monitors 155 miles away picked up tremors from it.
The Ayles Ice Shelf, roughly 41 square miles in area, was one of six major ice shelves remaining in Canada's Arctic.
Scientists say it is the largest event of its kind in Canada in 30 years and point their fingers at climate change as a major contributing factor.
''It is consistent with climate change,'' Vincent said, adding that the remaining ice shelves are 90 percent 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.''
