The deniers I know are conservatives who reject it outright simply because it's what the liberals believe (or perhaps, to find some common ground, it's what liberal institutions believe). They've read little about it and assume that it's hysteria. Maybe my idea of a conservative celebrity is a silly idea and won't work, but I believe the root cause is one of tribal conflict (combined with cynical disinformation campaigns), and to change their mind requires getting around these tribal defenses in some way. According to Pew, 84% of Liberal Democrats think that humans significantly contribute to global warming, whereas 14% of Conservative Republicans do. I think this helps to confirm that there's a pretty important tribal dimension at play here (although we also can't rule out that financially self-interested people have self-selected themselves into the latter category).
