Canada's foundation - permafrost - may be more solid than previously thought, scientists say.
University of Alberta geologist Duane Froese, lead author of a report today in the journal Science describing the ancient permafrost found just south of Dawson City. Scientists speculate that their results may cast doubt on a number of assumptions about past temperature measurement that predict immediate catastrophic Climate Change.
A swath of frozen mud and ice, inadvertently exposed by miners in the Central Yukon, is proving to be scientific gold. The permafrost turns out to be about 740,000 years old and contains the oldest ice yet uncovered in North America, researchers say. It predates the arrival of long-extinct creatures such as the woolly mammoth, and has weathered some remarkable swings in the climate, including two notable warm spells 120,000 and 400,000 years ago when temperatures were higher than they are today.
The discovery suggests permafrost more than a few metres below the surface, and the huge store of carbon it contains, may be more stable than previously thought.

This article was too good! One wonders how long after the movie came out that someone twigged to the problem. The National Post has done a good job on covering this story. It seems to simple to take the Casino's on from this story.
