Cryoturbation, the burial of topsoil material into deeper soil horizons by repeated freeze–thaw events, is an important storage mechanism for soil organic matter (SOM) in permafrost-affected soils.

The authors suggest one of the main drivers of the tundra’s shift from CO2 absorber to emitter could be thawing permafrost, which covers almost half of Canada’s land mass. “This is not ...

Scientists warn that the Siberian tundra could disappear by the year 2500 if greenhouse gas emissions are not reduced. The melting of permafrost could pose serious problems for our planet.

ORNL scientists created a high-performance simulation of the Arctic tundra that found the process of soil subsidence due to permafrost thaw would be self-limited in the decades ahead.

The climate in the tundra biomes is extremely cold - I mean seriously ... mean that one of the main features of the environment is permafrost which, as the name suggests, means permanently frozen ...
