There is no actual “science” in observing CO2 levels increased and global temperatures increased at the same time therefore concluding CO2 causes global temperatures to increase. That is a theory where the “signature” of CO2 as the cause has repeatedly failed to be observed based on what should happened if CO2 were in fact the cause. Or in other words, real science, has totally failed to make a solid connection between CO2 and global temperatures.
There is a connection that I have observed in the temperature and CO2 data. The CO2 concentrations follow global temperatures by 800 years. Temperature effects CO2 not the other way around.
