I know some very smart people who get very stupid as soon as the topic turns to AGW. These are guys who can strip the bark off a Creationist argument, point out all its logical flaws, and ridicule the stupidity behind them. They pinpoint and shoot down every bad argument - ‘It’s faith-based!”; “Scientists lie about believing it to keep their grant money!”; “Scientists fake their data to push some nefarious purpose!”

Change the topic to AGW, though, and they start making EXACTLY THE SAME ARGUMENTS, right down to the ‘nefarious purpose’ one (to destroy Capitalism).

It’s disheartening.
