River buries permafrost carbon at sea

A new study found that Arctic rivers, such as the Mackenzie River, are responsible for burying large amounts of organic carbon from thawing permafrost at sea. This process locks away carbon dioxide and helps stabilize the earth's CO2 levels over time, providing a potential natural sink for excess greenhouse gas emissions.
