The map is presented at a scale of 1 to 2,500,000 and shows the correlation of physiographic province to presence of permafrost across the state of Alaska. The digital data were prepared under the U.S ...

It’s evidence that permafrost, the long-frozen soil below the surface, is thawing. That’s bad news for the communities built above it – and for the global climate. As an ecologist ...

As it thaws, the permafrost is releasing greenhouse gases like carbon dioxide and methane – both of which accelerate global warming. Permafrost is ground that remains permanently frozen, typically ...

In 2009, she published her findings in one of the first research papers on N 2 O emissions from permafrost soils. In her current research project "Constraining the global permafrost nitrous oxide ...

Here, climate change is intensifying at a rate two to four times faster than the global average, accelerating the thawing of frozen ground under the boreal forests and tundra. This permafrost ...

It’s evidence that permafrost, the long-frozen soil below the surface, is thawing. That’s bad news for the communities built above it – and for the global climate. As an ecologist, I study these ...

Despite their critical role in mitigating climate change and providing essential ecosystem services, peatlands face significant threats and remain among the most poorly understood and under-monitored ...

As part of the Global Carbon Project, we have now published the first full greenhouse gas budget tallying sources and sinks for the northern permafrost region. It contains a mixed bag of good and ...

The permafrost regions, located just south of the Arctic, are experiencing accelerated warming, causing the frozen ground to thaw and release substantial amounts of carbon and nitrogen. This thawing ...

The effort was part of a global assessment of all regions and oceans. Carbon on the move We found permafrost was a small to ...

Woolly mammoths, giant sloths and saber-toothed cats were a fact of life for early humans. New clues in Earth’s northernmost ...
