What Watts has shown is that he can get a lower warming trend for the continental USA than others get. All you have to do is systematically eliminate the data you don’t like, while ignoring things like station moves, instrument changes, and recording data at different times of day. Don’t you dare correct for known biases (unless of course doing so would make the estimate of global warming smaller)! And if the satellite data should be in better agreement with others than with yourself, don’t breathe a word about that.
The irony is that Watts is doing exactly what he accuses others of: tilting every aspect of the data and analysis to suit his ideology. The joke is that he actually thinks this is “science.”
Since his original chest-beating, it seems that even some of his co-authors (one can’t help but wonder, did they all even know they were listed as co-authors?) take exception to his methods. Alas, it looks like important details are missing which are required for those who want to check his results. I certainly didn’t find any links to the data or computer programs used. Doesn’t Anthony want to be audited?
