Pick your Climate Change culprit

Dr Timothy Patterson, Professor of Geology, Carleton University, Ottawa states:
If CO2 is of such critical importance to climate change why was there a large temperature rise prior to the early 1940s when 80 percent of the human produced carbon dioxide was produced after World War II? When CO2 levels finally began to increase dramatically in the postwar years why was there a concomitant interval of about 30 years of cooling? One would think that if CO2 had such critical control over climate that the relative abundance of CO2 in the atmosphere would be in lock step with global temperature. Many researchers realize the difficulties that are presented by trying to make CO2 the key factor in climate change.
The following graph from Dr Patterson shows temperature anomaly plotted with sunspot cycle length and CO2 concentration. You tell me which one is more likely to be the culprit for our current warming cycle.

Who said the Sun can't change its spots ... it's also changing our CO2! ... maybe the ancients worshipping the Sun god weren't too dumb after all ...

So when are you going to come back and give us the benefit of your scientific opinion? Or where you just blamming my comments section for traffic?

If the science mattered, Bruce, then the lunacy of relying on computer models that have never been accurate would end.

Given that the sun clearly is the dominant influencer of our climate and water vapour is the dominant feedback mechanism you'd think that they'd be important parameters in climate models. But noooooooooo, it's the CO2 wot dunnit.

I say we all become carnivores, after all, plants consume CO2, and liberals talk it.
