"Surprising Geological Discovery: Ancient Rocks Emit CO2 Comparable to Volcanoes"

A study led by the University of Oxford has revealed that natural rock weathering can act as a significant source of CO2, rivaling volcanic emissions. This overturns the traditional view that rock weathering acts as a CO2 sink. The release of CO2 from rocks occurs when ancient seafloor rocks are pushed to the Earth's surface, exposing organic carbon to oxygen and water. This process, not currently included in climate models, could have implications for future carbon budget predictions and climate change scenarios. Further research will investigate whether human activities are increasing CO2 release from rock weathering and how it can be managed.
