It goes like this: beneath the ground is thick permafrost — a jumble of soil, rocks and sediment held together by ice. Underneath this sits a layer of “methane hydrates,” a solid form of ...

That’s a problem because the permafrost holds enormous amounts of vulnerable carbon, more than twice as much carbon as is already present in the atmosphere. Some of that carbon is now on the move.

When permafrost soils thaw, the microbes find more organic material they can convert. As a result, nitrogen and nitrous oxide can also be outgassed from these soils. Small-scale climate models ...

Permafrost is different. Rather than the woodland, you’re fighting for your life amid the frozen ruins of what were once sprawling cities. Make sure you’ve wrapped up warm, because the Steam ...

Evidence of human-caused climate change is mounting across the permafrost extent. The disappearance of large lakes, multiple square miles in size, is one of the most striking examples of recent ...

They are common on hillsides and along shorelines. The basic mechanisms of slumps are well described in the permafrost literature. But less well understood is what causes them to form, especially ...

The northern permafrost region, extending just south of the Arctic Circle, represents one of the planet’s most rapidly warming landscapes. Here, climate change is intensifying at a rate two to ...

For example, the Mackenzie mainstem site saw a ... Thermokarst processes, which involve thawing permafrost and ground ice, ...
