This video shows Naomi Oresekes talking to Liberal Senator, Nick Minchin, a climate change skeptic, explaining the error of his analysis of the subject.
This second video is her discussing her book, "Merchants Of Doubt", which explored the history of the denialism method of challenging scientific knowledge, so as to prevent any action being taken based on the agreed science.
I like her plain speaking, at about the 6:38 point in the video, she says, " I think it's quite threatening for ordinary citizens to realise that we've been duped, that we've been misled, and that what we think are HONEST debates, are actually NOT HONEST debates, that THIS (Denialism) is a Public Relations Campaign, whose intention is to deceive us, and that is a very hard thing to accept, nobody likes to admit, that they've been duped, but I think in the book, we show pretty clearly that we've all been victims of this DISINFORMATION CAMPAIGN".
I guess the desire to believe anything which does not comfortably fit your world view is hard for everyone, but surely there has to come a point where only the lunatic fringe will maintain their allegiance to Climate Change Denialism.
