A huge Canadian ice shelf 500 miles (800 kilometers) from the North Pole has disintegrated, leaving a large floating island of ice stranded 30 miles (48 kilometers) offshore, scientists reported yesterday.

Before the breakup the Canadian Arctic had six ice shelves.

"Now there are five," Copland said. In the past hundred years, he added, Canada's ice shelves have shrunk by 90 percent.

Earlier this month scientists reported that global warming may mean that the Arctic Ocean's summer sea ice will be completely gone by 2040.

And recent studies have shown that a loss of Arctic ice is causing polar bear populations to plummet, leading to a proposal to include the bears on the U.S. endangered species list.

Well. That's kinda scary. I like polar bears.

Wow. This climate change thing has sparked quite a debate. I have to say I am not convinced this weather is a normal climate pattern. Here in Ottawa we just recently got our first real snowfall and below 0 temps... in mid January!

To a certain extent, that's due to El Nino....milder and slightly wild weather all across the country.

I would say that this one year is not proof of global warming, but over the course of the last twenty years (or slightly longer) there has been a distinct rise in global temperatures.
