Permafrost - Climate Change, Thawing, Arctic: Permafrost is the result of present climate. Many temperature profiles show, however, that permafrost is not in equilibrium with present climate at the sites of measurement. Some areas show, for example, that

The Batagaika Crater is one of the few places to see a wall of permafrost—and whether it's thawing—up close. Scientists study the area for clues about climate change in the Arctic and how it may affect the rest of the planet. ...

Increased active-layer thicknesses have also been observed since the 1990s in some regions, including a change of 0.4 m in the Russian Arctic. Simulations unanimously indicate that warming and thawing of permafrost will continue in response to climate change and potentially accelerate, but there...
aClimate change is causing widespread thawing and degradation of permafrost, which has associated impacts on infrastructure, ecosystems and the carbon cycle in the high latitudes. 气候变化导致永冻土的普遍解冻和退化,同对基础设施、生态系和碳循环的冲击联系在一起在高纬度。[translate]...
A large amount of organic carbon stored in frozen Arctic soils (permafrost) could be released as carbon dioxide and methane in a warming climate, which would accelerate the pace of climate change; this review suggests that release of greenhouse gas emiss
Our research shows this ancient carbon is rapidly utilized by microbes and transferred to the atmosphere, leading to further warming in the region and therefore more thawing. So we get into a runaway effect." Spencer and a team of researchers first began looking at this issue of what happened...
