Initial assessment on the carbon emission rate and climatic consequences during the end-Permian mass extinction
Numerous lines of geochemical and stable isotopic evidence indicate that the end-Permian mass extinction was accompanied by abrupt climate change induced by CO 2 addition. Catastrophic end-Permian Siberian volcanism may have released a large amount of CO 2 into the atmosphere and pushed the Earth...

Numerous lines of geochemical and stable isotopic evidence indicate that the end-Permian mass extinction was accompanied by abrupt climate change induced by CO 2 addition. Catastrophic end-Permian Siberian volcanism may have released a large amount of CO 2 into the atmosphere and pushed the Earth's system beyond a critical threshold, causing the mass extinction. However, the injection rate, total amount and source of CO 2 are largely unknown. We conducted a suite of simulations using the recently published carbon isotope records and U-Pb ages from Meishan section in Zhejiang province, China. An Earth System Model of Intermediate Complexity (cGENIE; http://www.genie.ac.uk) was used to extract the pattern of CO 2 release needed to replicate the observed carbon isotope excursion across the Permian-Triassic boundary. This analysis leads us to suggest that the source of CO 2 must have been significantly heavier than typical biogenic or thermogenic methane to explain the significant warming that occurred during and after the extinction event.
