Can you assure me that 500 ppm CO2 or 600 ppm CO2 won't cause warming that will be irreversible?

There's not good reason to think so. Carbon's warming effect is exaggerated. The models which predict catastrophe rely on presumed major positive feedbacks that magnify the greenhouse effect of CO2. The feedbacks may actually be negative.
