Ok. So you agree totally co2 lagged warming in the past. You essentially agree this is a fact, no argument about it. So how did you think we misunderstood this fact? Or how did you think we misrepresented this fact? Those hockey-stick type of graphs that show temperature going back a thousand years have been used by many to indicate the rise in co2 causes a rise in temperature. If we neglect for a moment the data for the last 200 years or so, do you think in the past temperature rise is mostly driven by co2?
