Where
Arctic and northern high latitudes ·
Why
Current climate models often underestimate permafrost carbon stocks and omit deep carbon deposits, leading to an incomplete understanding of permafrost carbon decomposition.
The Frontline Impact
How this affects you
The earlier-than-expected transition of permafrost from a carbon sink to a source means more greenhouse gases will be released into the atmosphere, accelerating global warming and necessitating more urgent climate mitigation strategies worldwide.
