Perhaps most surprising to me personally is the Vostok ice core data that goes back 100’s of thousands of years as shown plotted in the graph below. You’d be right if you concluded that this data shows a clear correlation between Co2 and temperature. But a closer analysis reveals (not discernible in the graph) that the CO2 lags behind the temperature by an average of 800 years! Temperatures do indeed appear to control carbon and not the other way around (perhaps through temperature driven solubility changes in sea water). And while it’s possible that carbon also influences temperature the data don’t show much evidence of that. As temperatures rise, on average it takes 800 years before carbon starts to move. The extraordinary thing is that this CO2 lag is well accepted by climatologists, yet virtually unknown outside these circles.
