Via Tamino (Tisdale Fumbles, Pielke Cheers) I find Tisdale at WUWT talking nonsense - nothing new there. Tamino points out the obvious flaw in the argument (if you can call it an argument; to be fair, it is hard to tell what Tisdale wants to say, other than "its all wrong"), and then Nick Stokes is kind enough to tell the Watties (I did wonder if any of them might be good enough to think of it for themselves, but no such luck). But! The knowledge does not fit their worldview, so even when presented with the obvious they are still unable to understand it.
Steady on, that's only a minute slower than me :-)
[It hurt though. It will be a while before I'm any faster. Next summer, probably -W]
