Thawing permafrost releases greenhouse gas from depth

Which effects did the heat wave of summer 2020 have in Siberia? In a study led by the University of Bonn (Germany), geologists compared the spatial and temporal distribution of methane concentrations in the air of northern ...

Permafrost carbon loss reduces microbial stability

Chinese researchers have recently discovered links between reduction in microbial stability and soil carbon loss in the active layer of degraded alpine permafrost on the Qinghai-Tibet Plateau (QTP).

Team unravels mysteries of carbon release in permafrost soils

Like detectives, Argonne scientists are studying clues from the release of carbon in thawing permafrost regions, piecing the clues together to create detailed maps to predict the impact of rising global temperatures on future ...

Scientists use forest color to gauge permafrost depth

Scientists regularly use remote sensing drones and satellites to record how climate change affects permafrost thaw rates—methods that work well in barren tundra landscapes where there's nothing to obstruct the view.

Long-term permafrost record details Arctic thaw

Frozen Arctic soils are set to release vast amounts of greenhouse gases to the atmosphere as they continue to thaw in coming decades. Despite concerns that this will fuel future global warming, the scale and speed of this ...

Bacteria release climate-damaging carbon from thawing permafrost

A new study based on scientific sampling of a rusty carbon sink at a permafrost peatland at Sweden has revealed that iron minerals fail to trap organic carbon, a vast source of CO2 and methane not included in global warming ...

Getting to the bottom of Arctic landslides

Erosion of the frozen soil of Arctic regions, known as permafrost, is creating large areas of subsidence, which has catastrophic impact in these regions sensitive to climate change. As the mechanisms behind these geological ...

Watching the Arctic thaw in fast-forward

The Arctic is warming more quickly than almost any other region on Earth as a result of climate change. One of the better known: the continually shrinking summer sea-ice extent in the Arctic. But global warming is also leaving ...

Abrupt permafrost thaw alters microbial structure and function

Permafrost thaw could emit substantial carbon (C) into the atmosphere, and possibly trigger a positive feedback to climate warming. As the engine of biogeochemical cycling, soil microorganisms exert a critical role in mediating ...
