Did you respond to the wrong post - that looks like long term CO2 data without error bars whereas post 5 was about the last 100 years.
They both seem to peak together and then fall together, why is that? If CO2 leads and is causing the temperature to go up, then it would seem that if we want the temperature to go down, then we need to pump as much CO2 into the atmosphere as we can until we hit that critical peak point and they both fall. But what about at the low end? We have such a low concentration of CO2 that the temperature starts to increase? Why would that be?
