I understand where you're coming from but the science does not agree. You're only considering one variable (carbon dioxide amount), when in fact you need to consider the system as a whole to understand the effect of that one variable (i.e. What was the geothermal activity? What was the plant life activity? How was the sun behaving?). These things are being studied thoroughly and the general scientific consensus is that, yes, human caused climate change is a big deal. Carbon dioxide is only one part of the analysis however.
Another point in the conversation that is often missed is that water vapour itself is the most abundant greenhouse gas. Humanity is significantly affecting the water vapour all over the world and this is causing some serious changes to the global ecology. For example, I agree that nuclear is a viable option but current nuclear plants are serious water vapour emitters. Similarly, agriculture is brutal for this but it's sorta necessary to, you know, keep us all alive. All avenues for energy generation should be investigated and optimized to create a go forward strategy.
My main point with all of this is that it is imperative that we continue as a species to investigate and understand the true effects we have on our home. Individuals who deny this or seek to cut scientific efforts are at best short-sighted or at worst, willingly destroying the world for a few bucks.
