As permafrost thaws, the rocks once contained within it are dissolving, new research finds
Minerals released by thawing permafrost can eat away at exposed rocks, releasing even more carbon dioxide into the atmosphere.
Across the north, permafrost is thawing and releasing carbon dioxide, methane and other greenhouse gases. Scientists estimate that permafrost stores about 1,400 gigatons of carbon — nearly double the amount currently in the Earth’s atmosphere (about 850 gigatons).
