Overgrazing disrupts entire ecosystem

The Tibetan highlands have a special significance both as a grazing ecosystem and global carbon store. Furthermore, it plays a key role in the formation of the monsoon and supplying of potable water for a fifth of the earth's ...

Microbial response to a changing and fire-prone arctic ecosystem

Greenhouse gas emissions from human activities have caused Earth's climate to change—and in Arctic regions, air temperatures are warming twice as fast as the global average. Permanently frozen Arctic soils located in tundra ...

Lower methane emissions when permafrost disappears

Thawing permafrost in the Arctic does not always have to lead to increased emissions of the greenhouse gas methane. When thawed soil dries up, emissions can decline instead. A new study at the University of Gothenburg demonstrates ...

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 ...
