Center for American Progress’s fav pop-psych term, "denier," best applies to addicts refusing to admit to their problems. "Climate denier" implies the Catastrophic Anthropogenic Global Warming hypothesis is so obviously correct that only the clinically delusional could doubt it.
CAP’s first "Deniers in Congress" report defines "climate denier" as anyone:
questioning the "scientific consensus" on climate change; or,
saying: "the climate is always changing;" or,
not believing climate change poses a serious threat; or,
questioning the extent of human contribution to climate change.
