Arctic permafrost melting will aggravate the greenhouse effect

Scientists from Russia and the United States studied the composition of the deep layers of permafrost in Eastern Siberia to better understand the hazards of the permafrost thawing to our planet and its inhabitants. Their ...

Controls on nitrogen nutrient availability in the Arctic tundra

Near the top of the world, plants grow on soil that rests atop permafrost, or permanently frozen soil. Just like plants in warmer regions, these need nitrogen to grow. The unique aspects of the permafrost environment create ...

The pace at which the world's permafrost soils are warming

Global warming is causing increasing damage in the world's permafrost regions. As the new global comparative study conducted by the international permafrost network GTN-P shows, in all regions with permafrost soils the temperature ...

How to get nuanced details at the top of the world

At the top of the world, once permanently frozen soil holds vast pools of carbon. Microbes could free that carbon under the right conditions. To predict how the Arctic will respond to seasonal freeze-thaw-growing conditions, ...

Study links climate policy, carbon emissions from permafrost

Controlling greenhouse gas emissions in the coming decades could substantially reduce the consequences of carbon releases from thawing permafrost during the next 300 years, according to a new paper published this week in ...
