I'm not sure I'd be willing to dismiss that (we're over 400 ppm atm), considering the change in atmosphereic concentration changes albedo, increases ocean acidification (which we know alters rain-bands), and allows both the ocean and atmosphere to store more physical energy. It's bound to have significant effects on plant and animal life, and it clearly is.
Dude, the planet was tropical, had 40 hour long days, and Mosquitos could be measured in feet. This is when the primary element in the atmosphere was Oxygen, not Nitrogen like it is now.
The Earth's Climate has changed radically in it's geologic past.
The Earth's surface was once covered by over a mile of ice.
what's the pretext of CO2?
