Anthony Watts has joined the sky dragon slayers he used to ban from his blog at WUWT. Well, he used to ban some of them. He's joined forces with Rick "Neanderthal" Perry, the US Secretary of Energy, who rejects climate science outright.The sky dragon slayers are among the dumbest of the dim deniers, who don't believe the science of climate change. Most of them have spent their retirement years trying in vain to disprove the greenhouse effect. Sky dragon slayers reject the notion that carbon dioxide is a greenhouse gas and is causing global warming. They think our planet stays warm by magic, or from the warm breath of their god, or from pixie dust, or something.
