Abstract, Nature 435: 479-482; May 2005. Using the stomatal index method. Although multiple forcing factors may have contributed to the abrupt spike in atmospheric CO2, the authors suggest that the likely dominant forcing factor was oxidation of methane gas generated by subsurface thermal metamorphism of organic-rich late Permian and late Triassic coal bearing strata during magmatic intrusion of the Karoo-Ferrar large igneous province of southern Gondwana.
