Rivers are exhaling ancient carbon β and climate math just changed

Ancient carbon thought to be safely stored underground for millennia is unexpectedly resurfacing literally. A sweeping international study has found that over half of the carbon gases released by rivers come from long-term, old carbon sources like deep soils and weathered rocks, not just recent organic matter. This surprising discovery suggests Earth s vegetation is playing an even bigger role in absorbing excess carbon to keep the climate in check.
