New permafrost forming around shrinking Arctic lakes, but will it last?

PhysOrg: Researchers from McGill and the U.S. Geological Survey, more used to measuring thawing permafrost than its expansion, have made a surprising discovery. There is new permafrost forming around Twelvemile Lake in the interior of Alaska. But they have also quickly concluded that, given the current rate of climate change, it won't last beyond the end of this century. Twelvemile Lake, and many others like it, is disappearing. Over the past thirty years, as a result of climate change and thawing permafrost,...
Permafrost thawing could accelerate global warming

ScienceDaily: A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends. The research is featured in the newest edition of the Proceedings of the National Academy of Sciences. "We've known for a while now that permafrost is thawing," said Suzanne Hodgkins, the lead author on the paper and a doctoral student in chemical oceanography at Florida...

Permafrost thaw exacerbates climate change
2014-03-22 18:59:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The climate is warming in the arctic at twice the rate of the rest of the globe creating a longer growing season and increased plant growth, which captures atmospheric carbon, and thawing permafrost, which releases carbon into the atmosphere. Woods Hole Research Center (WHRC) Assistant Scientist Sue Natali and colleagues engineered first-of-a-kind warming experiments in the field to determine net gains or losses in carbon emissions. The study entitled "Permafrost degradation stimulates carbon loss...

The Upside To Thawing Permafrost Is...Nothing, It's Bad

Science 2.0: Every dark cloud has a silver lining and the silver lining for a thawing permafrost is...still a dark cloud. The climate is warming in the Arctic at twice the rate of the rest of the globe. That has led to a longer growing season and increased plant growth, which captures atmospheric carbon - that is good - but it is thawing the permafrost, which releases carbon into the atmosphere. Permafrost contains three to seven times the amount of carbon sequestered in tropical forests. A thawing permafrost...

Oil drilling wastes, long buried under Canada's permafrost, leak into environment
2013-11-16 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: For decades, companies exploring for oil and gas in the Arctic's remote southern reaches have disposed of their drilling waste in the cheapest and most convenient way possible: by digging massive pits to hold the waste and then capping them with frozen permafrost. And for decades, the waste harmlessly sat in the frozen tombs. Then climate change, which scientists say is caused by burning fossil fuels, set in, causing the permafrost to begin melting. A "sump" of oil drilling mud, supposedly...
