But it is S&C who have corrected the data and no one has ever called them global warmers. That is what is the key point here. This is the dataset that the skeptics use to deny global warming. I will also point out that there are other datasets produced by other scientists that show more warming than S&C. For example RSS (the people who pointed out S&C's error to them) has a rate of about 0.17 (posting from memory) as opposed to S&C's 0.12
No, this is one of many datasets that skeptics use to deny global warming. And skeptics are denying that there is a warming trend, what is at issue is the effect man has on it and the enormous number of assumptions put into the models which produce whacky predictions. Global warmers have a religious view of their models.
