Need an Ice breaker?

There are folks, even on my campus, who still argue that human activities are not contributing to global warming and climate change. Anyone who has breathed the exhaust coming out of a petro-fuel based engine should understand the deadly nature of the carbon emissions.
Chicago Tribune reports that "19-square-mile chunk of ice breaks loose from Arctic ice shelf in Canada's far north." According to the story "A chunk of ice shelf nearly the size of Manhattan has broken away from Ellesmere Island in Canada's northern Arctic, another dramatic indication of how warmer temperatures are changing the polar frontier, scientists said Wednesday.

Derek Mueller, an Arctic ice shelf specialist at Trent University in Ontario, told The Associated Press that the 4,500-year-old Markham Ice Shelf separated in early August and the 19-square-mile shelf is now adrift in the Arctic Ocean."
