Global warming blamed for ice melt

Scientists say global warming is melting one of Canada’s last remaining ice shelves.

The edges of the Ward Hunt Ice Shelf, located about 2,175 miles north of Edmonton, are melting.

Ward Hunt is the largest of five separate shelves that once comprised the 3,000-year-old Ellesmere Island Ice Shelf, which has lost 90 percent of its mass in less than a century.

The Bush Administration has responded to increased calls, including by ranking Republicans, to take serious action against global warming, with the sound of more crickets.
