Arctic temperatures are the warmest in more than 10,000 years, speeding the thaw of permafrost in Canada’s North, according to a new Canadian study. of the University of Alberta.

"We’ve known that the last few decades have been very warm. But we’ve found that temperatures are on the order of two degrees Celsius warmer than any time in the last 10,000 years that was a surprise," Duane Froese, professor in the Department of Earth and Atmospheric Science, and Canada Research Chair in Northern Environmental Change said .

Froese, co-author of the study, said the resulting rise in permafrost thaw across the Arctic is destabilizing soil carbon, which may further accelerate warming.

The study found that previous record highs occurred during the early Holocene period around 9,900 and 6,400 years ago.
