Indeed, CO2 will go up as a result of temperature increases...

as the solubility of CO2 in water decreases with rising temperatures and it is liberated from the oceans. That is something you can demonstrate with a can of soda at home - take the can out from the fridge, more CO2 bubbles come out. But that doesn't mean CO2 doesn't cause temperature increases itself - both can be true, and similarly the effect of CO2 concentrations on temperature through radiative forcing is at this point (and, indeed, even in the early 1900s), so well-established that it is more of an accounting problem than a scientific one.
Think of it like the stock market - did people buy in because a stock is booming, or did the stock boom because people bought in? The answer is both. That's why scientists are so afraid of starting off the process - we might get caught in a positive feedback loop causing irreversible changes in the ecosystem.
Indeed, CO2 levels have been much higher in the earth's history, for example back when dinosaurs ruled the earth in the Cretaceous. Now, I wouldn't mind so much if we went back to that environment, as I'm rather fond of birds, but it doesn't leave much space for mammals like us, and unfortunately Aston maintenance requires opposable thumbs...
Anyway, here are some peer-reviewed sources regarding radiative forcing
www.nature.com
"Our study unambiguously shows one-way causality between the total
Greenhouse Gases and GMTA. Specifically, it is confirmed that the
former, especially CO
2, are the main causal drivers of the recent warming." and regarding boundary conditions for mammalian life
www.nature.com
"If
CO2 partial pressure was to spike ≥560 ppm, even for a short period (10
2–10
3 years),
Earth will become inhospitable for mammalian life, resulting in a mass
extinction comparable to the ‘Big 5’ extinction events". Feel free to ignore or contest, but
do so with the knowedge that the overwhelming majority of scientists are not on your side.
