Nah, they're watching hurricanes get more intense every year or two and still manage to bury their heads in enough sand that they can't remember anything related to hurricanes since before katrina (therefore, none of it happened)

There's also a lot of money in climate denial for the rightist grifters, and the rules of most online forums play into the whole, "if I can find a citation, no matter how reputable, my information is at least as truthy as the 5 peer reviewed research papers that contradict everything I proposed" mentality.
