is the weather severe enough?, page-307

Rubbish. It's a feedback loop. Temperature and CO2 can drive each other, depending on the situation.

That's why it's so dangerous to earth based species when they change too fast - you get a reinforcing feedback cycle.

But actually think about what you are saying when you say CO2 "always" follows a temperature rise.

Do you really think it was changes in weather that drove the CO2 emissions of volcanoes 250 million years ago?

Do you really think it was changes in weather that caused humans to choose fossil fuels as the backbone of their energy production and emit CO2 currently n the modern era?

Come on.
