Recent change of Arctic tundra ecosystems from a net carbon dioxide sink to a source
Abstract
Data are presented which indicate that the tundra on the North Slope of Alaska has become a source of CO2 in the atmosphere. This change coincides with recent warming in the Arctic. The results suggests that tundra ecosystems may exert a positive feedback on atmospheric CO2 and greenhouse warming.
