Wow, you completely ignore the fact that CO2 lags temp.
Recent research casts serious doubt on that. No matter, we can go with the old theory anyways.
First, the temperature lowered and thus the atmospheric CO2 dropped as well.
So the 600 - 1000 year lag period apparently got way quicker in this case. Why? Who knows. Magic.
Then, when the recovery occurred the CO2 levels have increased. Exactly the same as has happened every time before. That is irrefutable evidence that CO2 has no bearing on the global temperature.
And you're ignoring the snowball earth case. If it wasn't CO2, explain for us what caused the warming that pulled the earth out of snowball mode. The sun didn't get hotter. "Orbital factors" certainly had no effect. When the whole world is frozen and north and south have the same white albedo, orbital changes will do nothing.
How about this new NASA study that says CO2 COOLS the atmosphere. What do you think of this?
“Carbon dioxide and nitric oxide are natural thermostats,” explains James Russell of Hampton University, SABER’s principal investigator. “When the upper atmosphere (or ‘thermosphere’) heats up, these molecules try as hard as they can to shed that heat back into space.”

I think, since the earth gets over 200 million gigawatts in solar energy, mere "gigawatts" is an insignificant amount of energy in relation to the global energy balance. Hence, that study has nothing to do with global warming.
You KNOW what orbital "factors" existed back then??? Please do tell... How many degrees of freedom are there to earth's orientation to the sun? It's NOT just tilt about the equator..
