Organic carbon in permafrost
With ongoing climate change, the Arctic will continue to warm approximately twice as fast as the lower latitudes. As large parts of the Arctic are affected by permafrost, large-scale degradation processes such as thermokarst and thermal erosion are expected. Ice-rich permafrost, such as yedoma perma...
