Jersey Paul: "The bedrock driver of anthropogenic climate change is that CO2 change and temperature change have coincided,"
CO2 change and temperature change have historically coincided, yes - the correlation there is quite strong.
Jersey Paul: "thus CO2 must be responsible for temperature change."
Yes and no. Per the consensus global warming theory, CO2 is the primary initiating driver in man-made temperature change.
That however is not the same thing as saying that CO2 has always been the primary driver temperature change, and historically most if not all of the time it hasn't been. According to global warming theory CO2 has historically been a feedback driver with respect to global warming, not the initiating driver. WHich is to say, once the earth started to warm, CO2 released from the earth as a result created a feedback loop that re-enforced the warming cycle.
Jersey Paul: "Careful look at the data shows temperature change occurs first, then CO2 change.
Before the current warming trend that has been the case, yes. Again CO2 has historically been a feedback driver with respect to global warming, not the initiating driver.
