Permafrost zones extend over 50% of Canada's land area. Warming or thawing of permafrost due to climate change could significantly impact existing infrastructure and future development in Canada's north.
Researchers Jennifer Throop and Antoni Lewkowicz at the University of Ottawa, along with Sharon Smith with the Geological Survey of Canada, have published a new study, part of an upcoming special issue of the Canadian Journal of Earth Sciences (CJES), that provides one of the first summaries of climate and ground temperature relations across northern Canada.
Dr. Christopher Burn, Editor of the CJES special issue on fundamental and applied research on permafrost in Canada, says the study by Throop, Lewkowicz, and Smith is unusual because it presents data on permafrost throughout Canada's three northern territories.
Most previous reports have concentrated on restricted regions within the North, but this paper presents conditions at the continental scale. This summary shows the factors that govern the response of permafrost to climate change, and indicates how the emphasis on snow conditions, soil moisture conditions, and surface peat and moss varies across the North.
"This important research gives strategic assistance in projecting how permafrost may change with the climate, as it pinpoints important characteristics, and demonstrates how these vary from place to place," says Burn.
"The response of permafrost to climate change is a critical factor Canadians must anticipate if our northern infrastructure is to be adapted to thawing ground."

No biggie. With business as usual, the permafrost will simply release all of that methane and make it warm and toasty. We don't need ecosystems to survive anyway. Humans are the chose species of the universe. We don't need to abide by rules of nature or care for it. Just keep that cash and oil flowing. - 1 year ago

JanforGore:
Perhaps a more sensationalistic title like 'Mitt Romney's Dog Drowns In Melting Ice' would get people's attention.
