is the weather severe enough?, page-316

You don't know what my "side" is if you think that.

It's long been known that the mass extinction event 250 million years ago was driven by warming caused by greater than usual CO2 emissions from greater than usual volcanic activity.

We've probably known that longer than you've been alive.

Excess CO2 has negative effects. To pretend otherwise with all the evidence we have only speaks to your ignorance.
