The Muller episode remains, arguably, a matter of interest, but Anthony Watts appears to have completely overreached in response (note point 4; via Joel D. Shore in comments at Tamino’s).
Tamino’s merciless demolition says all that needs to be said about it:
Some consider it hypocritical that Watts should make such a big fuss, including a “press release,” about a paper which isn’t yet even submitted for publication, let alone peer reviewed or accepted for publication, after he so scathingly criticized Richard Muller for doing pretty much the same thing some time ago with the initial results of the Berkeley study. Apparently, for Watts it’s OK to trumpet unpublished work which agrees with his ideology, but it’s a mortal sin when it disagrees with him.
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.
In other words, we’re rapidly approaching the moment when denial is no longer possible for the sane.
