Thawing Permafrost: Rocks Like Carbon Sinks May Offset Emissions, Study Finds
TL;DR
A Nature study across 50 rivers on China's Qinghai–Tibet Plateau shows that thawing permafrost accelerates rock weathering, which consumes atmospheric CO2 and can offset or even exceed river CO2 emissions in some catchments, suggesting geological processes may partly counterbalance thaw-induced carbon release.
