Also, data needs to be sourced carefully when people’s religion is involved. I have no idea where this data came from, so first it would need to be verified. If this is done, then we are faced with a graph of data on one hand, and absolute evidence of previous warming climate on the other where CO2 was not elevated. This would logically mean that CO2 is not a driving force (at least of significance) in the cycle since it happened to a greater degree 800 years ago without the CO2 increase.
My overall point is that there is certainly not enough information clearly available to make the moves that the pseudo religious zealots want to make.
I am all for moving to a cleaner environment. I am pro nuclear energy. I like the idea of electric cars - but from a pollution standpoint since that is what evidence clearly supports.
