Thawing permafrost may trigger overlooked carbon sink in rivers
New research on the Qinghai–Tibet Plateau reveals that thawing permafrost may trigger increased rock weathering, which consumes atmospheric CO2. This process acts as a previously overlooked carbon sink that partially offsets the greenhouse gas emissions typically associated with melting permafrost.
Why it matters
Understanding this geological feedback loop is crucial for more accurate climate modeling and predicting the long-term impact of permafrost degradation.
