Sea level fall during glaciation stabilized atmospheric CO2 by enhanced volcanic degassing

Ice core data show a breakdown in the long-term temperature-atmospheric CO2 correlation during interglacial-glacial transitions. Here, via a novel modelling approach, the authors reveal marine volcanism, triggered by a fall in sea level, as a likely mechanism for the observed delayed decline in atmo...

Summary:Ice core data show a breakdown in the long-term temperature-atmospheric CO2 correlation during interglacial-glacial transitions. Here, via a novel modelling approach, the authors reveal marine volcanism, triggered by a fall in sea level, as a likely mechanism for the observed delayed decline in atmospheric CO2.
