James Wilt – There Is a New Climate Change Disaster Looming in Northern Canada

Of all the climate change issues that have been melodramatically dubbed a “carbon bomb” in recent years—tar sands projects in Alberta, catastrophic wildfires in Indonesia, holes in Australia’s seagrass meadows—it seems the thawing of permafrost in the Arctic is most likely to live up to the hype. There’s a staggering amount of methane and carbon dioxide, like hundreds of gigatons …

Permafrost thaw’s runaway effect on carbon release – Tim Radford

An international team of scientists has settled one puzzle of the Arctic permafrost and confirmed one long-standing fear: the vast amounts of carbon now preserved in the frozen soils could one day all get back into the atmosphere. Since the Arctic is the fastest-warming place on the planet, such a release of greenhouse gas could only accelerate global warming and …

Warming Climate May Release Vast Amounts Of Carbon From Long-Frozen Arctic Soils

More carbon is released into the atmosphere would amplify climate warming, and that, in turn, would cause more permafrost to thaw and release more carbon, causing the cycle to continue. Recent research by scientists has confirmed the suspicion scientists were making regarding the Arctic permafrost. Scientists estimate there is more than 10 times the amount of carbon in the Arctic …

Scientists predict gradual, prolonged permafrost greenhouse gas emissions, allowing us more time to adapt

A new scientific synthesis suggests a gradual, prolonged release of greenhouse gases from permafrost soils in Arctic and sub-Arctic regions, which may afford society more time to adapt to environmental changes, say scientists in an April 9 paper published in Nature. “Twenty years ago there was very little research about the possible rate of permafrost carbon release,” said co-author A. …
