Thawing permafrost accelerates greenhouse gas release
Permafrost thawing may allow greenhouse gases to escape at a much higher rate than previously thought, and this could further accelerate climate change....
School of Earth and Environment
Earth and Environment brings together physical, environmental and social scientists to solve global issues and to train the next generation of scientists....
role in determining the rate and extent of permafrost peatland thaw. Study lead author, Richard Fewster is a PhD researcher in the School of Geography at Leeds. ... protection the insulating properties of peat soils could provide.&rdquo...
Fortunately, simply-installed ventilation is all that is often required if the problem is recognised. “If the permafrost were stable, there would be no cause to be concerned. ... bulk of the permafrost thaws more slowly. ...
Permafrost peatlands approaching tipping point
New study indicates that despite efforts to reduce global carbon emissions, by 2040 the climates of Northern Europe will be unable to sustain peat permafrost....
Experiments by University of Leeds researchers, published in AGU journal Earth’s Future, have shown that thawing of permafrost makes it between 25 and 100 times more permeable, allowing more ... the research measured how changing temperatur...
Huge permafrost thaw can be limited by ambitious climate targets
Global warming will thaw about 20% more permafrost than previously thought, scientists have warned – potentially releasing significant amounts of greenhouse gases into the Earth’s atmosphere....

Large quantities of carbon are stored in organic matter trapped in the icy permafrost soils. ... It is estimated that there is more carbon contained in the frozen permafrost than is currently in the atmosphere....
Thawing permafrost could release cancer-causing gas
Thawing of permafrost due to climate change could expose the Arctic population to much greater concentrations of the cancer-causing gas Radon, a new story has found....
Emissions from wetlands and permafrost impacts climate targets
Additional cuts to fossil fuel emissions are required to limit global warming due to greenhouse gases from wetlands and permafrost, according to new research....
