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 ...

Siberia's permafrost erosion has been worsening for years

The Arctic is warming faster than any other region on the planet. As a result, permafrost that is thousands of years old is now being lost to erosion. As measurements gathered on the Lena River by AWI experts show, the scale ...
