We will have to agree to disagree on the chart. For better or worse, the 2016 global land+ocean anomaly is on track to be double 2006 (1.2 C vs 0.6 C), or .06 C past the cutoff of the y-axis and well above the reconstructed MWP peak.<p>&quot;E.g., was the Little Ice Age caused by less CO2? I doubt it!&quot;<p>Who knows? Based on what I could find from ice core studies it appears atmospheric CO2 was 5-10% lower from 1600-1800. I don&#x27;t anyone making a causative claim.
