There's little reason to believe many high-profile climate deniers are acting in good faith, especially those employed by think tanks and other PR organisations.

As the questions are political, you need rhetoric. As unfortunately as it may be, it should be obvious by now to everyone following politics that being "polite" is not a winning recipe in the game.

These people act as authorities as well. If the alternative is to appeal to another authority, then it seems like choosing not to change opinions is a reasonable course of action for somebody who is already convinced on the basis of authority. The public case for concern about climate change has been marred with incessant exaggeration (for example, lady liberty was supposed to be semi-submerged by now, and the north pole was supposed to be completely free of ice by 2013). The source of many Americans' (and Canadians') skepticism of climate predictions is a continuous outpouring of exaggeration and fabrication, especially on the part of Al Gore (whose film was shown to a significant proportion of Canadian school children [and I imagine, American school children as well] in the oughts).
