Alpine permafrost could account for a quarter of thawed carbon based on Plio-Pleistocene paleoclimate analogue

The stability of permafrost carbon is poorly understood. Here the authors use Plio-Pleistocene clumped isotope reconstructions from the Tibetan Plateau and climate simulation to determine that ~85 petagrams of alpine carbon is vulnerable to thawing.
