Overview of Permian Extinction
Explanatory Theories Regarding the Permian Extinction

From the Paper:

"It has been suggested that this increase in carbon-12 could be the result of upwelling of frozen methane hydrate from the ocean floor. Experiments have shown that a sea temperature rise of 5?C would be sufficient enough to gasify solid methane hydrate. This would lead to huge amounts of greenhouse gases being expelled into the atmosphere, and could have led to the mass extinction ("Permian-Triassic")."
