Die arktischen Permafrostböden tauen auf – Wechselwirkung mit dem Klima

About a quarter of the earth's land surface, a huge area, has permafrost soils; areas with permanently frozen subsoil. The summer thaw enables dense vegetation, such as the taiga in Siberia; however, many areas have low tundra due to the short summer. In the last few decades, the thawing layer...

Description
Summary:About a quarter of the earth's land surface, a huge area, has permafrost soils; areas with permanently frozen subsoil. The summer thaw enables dense vegetation, such as the taiga in Siberia; however, many areas have low tundra due to the short summer. In the last few decades, the thawing layer in the permafrost has increased significantly due to global warming. The consequences are unstable slopes and soils, disturbed vegetation and new lakes and great danger for infrastructure. In addition, greenhouse gases are also released, which intensify global warming.
