New paper out in Global and Planetary Change on the rate and magnitude of CAMP volcanism across the TJ extinction event and how it compares with modern anthropogenic CO2 emissions.
Anthropogenic-scale CO2 degassing from the Central Atlantic Magmatic Province as a driver of the end-Triassic mass extinction by Manfredo Capriolo, Benjamin J.W.Mills, Robert J.Newton, JacopoDal Corso, Alexander M.Dunhill, Paul B.Wignall and Andrea Marzoli. https://doi.org/10.1016/j.gloplacha.2021.103731
Our modelling shows that intense and pulsed volcanic activity alone may have caused repeated temperature increases of up to 5 °C and pH drops. Rapid and massive volcanic CO2 emissions from CAMP, on a similar scale to current anthropogenic emissions, severely impacted on climate and environment at a global scale, leading to catastrophic biotic consequences.
It is concerning that past mass extinction events, where around 50%+ of life in the oceans disappeared, we caused by environmental cascade effects caused by greenhouse gas emissions that occurred at a similar rate to modern anthropogenic emissions.
