High riverine CO 2 emissions at the permafrost boundary of Western Siberia
International audience The fate of the vast stocks of organic carbon stored in permafrost of the Western Siberian Lowland, the world's largest peatland, is uncertain. Specifically, the amount of greenhouse gas emissions from rivers in the region is unknown. Here we present estimates of annual C...
