You analysis is sloppy and flawed. I would be cautious drawing too many conclusions from it. Human contribution to “greenhouse warming” cannot be dismissed out of hand, as you appear to be attempting to do. Nor should we become hysterical and panicky because of dubious trends based on doctored data.
I admit it was back of the envelope calculations drawing from some papers I have. Can you give me your calculations so I can see where I am wrong?
Also if we’re no longer in the Quaternary, can you tell my why you say that? Cite some geologic papers maybe?
