Unfortunately, to draw an admittedly-loaded parallel, the anti-AGW movement is basically running the playbook of Holocaust deniers, whose preferred methodology is, in a nutshell, to drag some 90-year-old's memories out, say "AH-HA! You said this happened at 3:30 on April 12, but the camp's log says it happened at 3:42! Therefore <i>the entire Holocaust never happened and was made up by the Jewish banking conspiracy!</i>"<p>It's not any prettier when it's used to argue against climate change.
