Report: Canada warming up twice as fast as the rest of the world

The report on Canada's climate says the average temperature in the country is 1.7 degrees Celsius higher today than it was 70 years ago, while the average global temperature is up 0.8 degrees.

That indicates Canada is warming up twice as fast as the rest of the world and it's ``effectively irreversible.''

The report is from Environment and Climate Change Canada.

At stake is just how bad that warming gets, say several scientists who presented the Canada's Changing Climate Report in Ottawa.

The report is the first in a series of scientific assessments the department is producing and the first that zeros in on the changes Canada is seeing as a result of global warming.

The Canadian Arctic has been hit hardest, with a 2.3 degree increase, creating a risk that by the middle of this century most marine regions in the Canadian North will be ice-free for at least a month at a time.
