Carbon dioxide biggest player in thawing permafrost

Carbon dioxide emissions from dry and oxygen-rich environments are likely to play a much greater role in controlling future rates of climate change caused by permafrost thaw than rates of methane release from oxygen-poor ...

Permafrost: A ticking time bomb beneath our feet

Nearly a quarter of the Earth's land surface is permanently frozen. These areas, known as permafrost, are found in northern polar regions and at high altitudes. But the permafrost is now starting to thaw—with potentially ...

Permafrost thaw could release bacteria and viruses

When considering the implications of thawing permafrost, our initial worries are likely to turn to the major issue of methane being released into the atmosphere and exacerbating global warming or issues for local communities ...

Climate change is threatening unique permafrost landforms

As the permafrost thaws, the topography of the Arctic will alter dramatically, according to an international study headed by Finnish geographers. The study, which covered the entire area of permafrost in the Arctic, found ...
