Without CO2 life itself would be impossible.
The most that increased CO2 does is increase plant growth.
Formerly arid areas are greening up.
The temperature on earth is determined by the source of all heat, the Sun.
Figure out how to regulate the Sun if you want to control the temperature.

I think if we can send a glacier into the sun on a rocket, we could cool it down via an ice cube-like effect.
