like to know when higher co2 levels have ever been bad for life overall on Earth.


Life has been able to thrive for billions of years on Earth with worse conditions than are present today. That is not the argument here.

The argument here is the rate of change.

This is systems thinking. Need to use terms like: Sources, reservoirs, and flux.

Ok, the Earth is greening because of the increased co2. How is that a bad thing for life on Earth?
