"Warmist?"
Yeah, that one got me too. What exactly is a "warmist"?
Oh, it's self-evident what he's going for. It's a common tactic, to dismiss scientific ideas by painting those who accept them as "-ists" of one sort or another, ideologues blindly following a dogma. For instance, the way creationists (who do choose to call themselves that, I believe) refer to evolutionary theory as "Darwinism," which is ridiculous, because Darwin's work was just the bare beginning of a science that's been greatly added to and expanded and revolutionized by molecular genetics and the like -- so it's tantamount to referring to modern physics as "Newtonism." But groups like this believe that objective reality is not a thing, that only belief defines truth, and that anyone who disagrees with their beliefs is simply a practitioner of a rival faith.
