"So it is correct that CO2 did not trigger the warmings, but it definitely contributed to them -- and according to climate theory and model experiments, greenhouse gas forcing was the dominant factor in the magnitude of the ultimate change."

I'm surprised that they conceded that CO2 does not cause global warming. These people defend their voodoo climate fantasies like a religion. Their argument that CO2 is nevertheless the "dominate factor" is laughable and specious. They have no evidence of that except for highly questionable "model experiments." The correlation that they are looking for is with sun spot activity.

Global temperature increases have increased CO2 \ greenhouse gas levels. But do not worry when the earth begins to cool the greenhouse gases will begin to diminish.

They didn't concede that CO2 does not cause global warming.

They said that warming in the "way back" caused an increase in CO2 which in turn caused more warming via GH effect, and that CO2 caused most of the "ultimate change".
