This new fence-sitting position by Randi is quite surprising. He must have been affected by 'Climategate'.
I thought he was pretty firmly stuck in the pro-AGW camp for financial reasons if nothing else. His organisation, the James Randi Educational Foundation (JREF), gets a lot of its income from holding conferences. It holds something every year called the Amazing Meeting, of which the last one attracted over a 1000 delegates paying $300 a time, and there is also some sort of annual conference on a cruise liner. A lot of the participants at these conferences are, as I understand it, nerdy badscience zealots with a left-liberal worldview, the type of people who believe that public sector science is as pure as the driven snow. So even by taking up a neutral position, Randi could be irritating a lot of the people who turn up at his JREF conferences.
