A new global study reveals that ancient carbon, once thought securely stored in soils and rocks, is leaking into the atmosphere via rivers. For the first time, researchers have confirmed that carbon trapped in landscapes for thousands of years or longer can return to the atmosphere as carbon dioxide escaping from river surfaces. The study, […]



Summary

Ancient carbon, previously considered safely stored in soils and rocks, is now leaking into the atmosphere via rivers, according to a new global study. Researchers have confirmed that carbon sequestered for millennia can be released as carbon dioxide from river surfaces. This finding highlights a previously underestimated pathway for ancient carbon’s return to the atmosphere, potentially impacting climate models and our understanding of carbon cycling. The study emphasizes the need to re-evaluate the role of rivers in global carbon budgets and their contribution to greenhouse gas emissions.
