Global Warming is Undeniable By Jonathan Spicer

TORONTO (Reuters) - Aboriginal communities in Ontario's far north are becoming increasingly isolated as rising temperatures melt their winter route to the outside world and impede their access to supplies.

"The ice doesn't have its solid blue color any more," said Stan Beardy, the grand chief of Nishnawbe Aski Nation, which represents Ontario's remote First Nations. "It's more like Styrofoam now, really brittle."

"With the toxic waste moving north, and global warming, we don't have that solid ice anymore, and that's why we have problems with winter roads when it's mild."

The 34 First Nations reservations, scattered in boreal forest across northern Ontario, are accessible only by plane for much of the year. more..
