It's a moderately potent greenhouse gas. Not as potent as water or methane, but still pretty good. The first 200 ppm in the atmosphere is responsible for most of its contribution to the greenhouse effect. The next 200 ppm is going to have much less of a contribution because of the Beer-Lambert Law. So almost all of the warming that the Earth would experience from CO2 is already there. Going from 0 to 200 ppm gets you 12 W/m2. Going from 200 to 400 ppm gets you to 15 W/m2. This is supposedly what has happened in the last 150 years. Going to 800 ppm would get you to around 21 W/m2. I'm not worried about that.
