Thawing Permafrost Not Only Emits CO2, It Absorbs it Too, Shows Landmark Study
A new study published in Nature suggests that thawing permafrost may partially offset its own carbon emissions through increased chemical weathering in rivers. This process consumes atmospheric CO2, providing a previously overlooked natural carbon sink.
Why it matters
This discovery offers a more nuanced understanding of climate change feedback loops and the role of geological processes in carbon sequestration.
Thawing permafrost is considered a growing source of greenhouse gases as our climate warms and releases ancient carbon once stored in the frozen soils.
