If there is a saturation point of C02 then it appears that we have not yet reached that point. So increasing it's concentrations will have a positive feedback on tropospheric temperatures.
The following two papers make that clear from both satellite and terrestrial observations.

Yes in the historical record rises in C02 usually follow rises initially in temperatures. It's pretty clear though that the two are linked. For the most part periods of higher temperatures also had periods of higher C02 concentrations. So what happens when humans upset the normal balance by rapidly increasing the C02 concentrations over a relatively short period?
For anyone on here wanting to look at some real science and look at scientific discussion that debunks most of the myths that people like Sangetsu and Ryzorian peadle here I would suggest downloading the following
