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....
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....
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....
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....
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...
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....
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. ...
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...
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....
In permafrost regions the soil is permanently frozen, trapping large quantities of carbon in frozen organic matter. ... Warming climates cause the permafrost soil to thaw and emit carbon dioxide, and in some cases methane, into the atmosphere....
