I think the article has new information. It isn’t talking about temperature vs. CO2 eons ago. It’s talking about recent information. I think it is another nail in the coffin of CAGW.
Not that you’d know it from listening to the Republican candidate for president of the United States;
“Mitt Romney:
I am not a scientist myself, but my best assessment of the data is that the world is getting warmer, that human activity contributes to that warming, and that policymakers should therefore consider the risk of negative consequences.”
