Some context. Over at Keith Kloor's Ray Pierrehumbert, RealClimate blog founder, left a rather rude comment ending with this about troublesome voices like McIntyre, McKittrick, and Watts.
"... big as the IPCC tent may be, I hope there will never be a place in it for any of these clowns."
Which made me conclude that Ray thinks that the IPCC is a circus and it should only be populated by approved and accredited clowns. Fair enough.
