Ancient Carbon Leak Found to Endanger Climate Stabilization

New research shows ancient carbon is leaking into the atmosphere, raising concerns about climate impact.

Ancient Carbon Leak Could Threaten Climate Stability

Recent research published in Nature indicates a significant leak of ancient carbon into the atmosphere through rivers. Previously, it was believed that carbon trapped in soils and geological formations remained stable. However, scientists from the University of Bristol found that nearly 60% of carbon emissions from rivers originate from these long-buried sources. This challenges earlier assumptions that most river emissions were from recent organic material. Dr. Josh Dean, the lead author, noted that these findings could greatly impact how we understand global carbon emissions and climate change measures. The study calls for a reevaluation of carbon accounting in climate models to incorporate this newly discovered factor.

This groundbreaking discovery fundamentally alters our understanding of the carbon cycle. Rivers are now seen as significant conduits for ancient carbon, rather than just vehicles for newly generated carbon. If ancient carbon stores, once thought to be secure, are leaking, then the implications for climate policy could be severe. This study underscores a pressing need for scientists and policymakers to reassess both the sources and dynamics of carbon emissions. Addressing this leakage will be crucial as we strive to stabilize CO2 levels in the atmosphere and mitigate climate change effects.
