Josh, a challenge, huh?
Most of your questions are too non- specific to be of any use. Preindustrial CO2 was about 270 ppm, and it is currently around 380, an increase of ~30%, which is all from human influence.
I suppose that you want to argue that since water vapor is more prevelant in the atmosphere that CO2 does not matter. But this is faulty science and logic. CO2 is a far more efficient greenhouse gas than water vapor. In fact a lot of the warming scientists expect to see is the water vapor feedback from CO2 warming.
