Permafrost carbon emissions in a changing Arctic
Arctic permafrost stores nearly 1.700 billion metric tons of frozen and thawing carbon. Anthropogenic warming threatens to release an unknown quantity of this carbon to the atmosphere, influencing the climate in processes collectively known as the permafrost carbon feedback. In this Review, we discu...
