The End-Permian Extinction Event

I am sure you are aware that most species died out at the end of the Permian period.  I was watching a YouTube video about it and it seemed a bit too convenient that it cast the blame for the second temperature increase,  to 39 degrees Celsius worldwide, to the Siberian Traps carbon dioxide release producing 35 degree Celsius temperature that caused release of methane from tundra and deep sea methane hydrates.  The Wikipedia article is quite a bit more balanced and presented this as one possible explanation.   It is well worth reading if you are a geology nerd like me.
