Interesting article. I haven't read the link but I see the author is linking it to million years of volcanic activity. Maybe I'm wrong but I thought that a volcano releases a large amount of CO2. Where does this hypothesis lead you to make the connection that humans in maybe the last 200 years could equal or come close to 1 million years of volcanic activity, to even reach that amount in a fraction of the time.

Like I said I think it's interesting, but where is the link you are guessing to human activity?

The correlation with contemporary global warming is implied, not stated. This allows the author to let the majority of casual readers assume a connection, but then can deny he stated any connection when challenged by someone like you.

After all, what's the point of posting an article on CO2 and extinction if there wasn't currently a CO2 debate? I mean if the theory was related to O2 levels, this article wouldn't be of any interest.

Once they figure out that cars, factories, and human agricultural activities caused the high CO2 that caused the mass extinction, then I'll become interested. Otherwise, the discussion is completely academic.
