If you believe, that anti-climate-change propaganda machinery is fuelled only by the stupidity of deeply indoctrinated neocons, than think twice. It is a powerful, well funded (by scams like Koch brothers), and very well orchestrated campaign.
Here is a classic example of how such manipulative campaign works. It starts with out-of-context quotations of an old publication, and with the time more fantasies are being added. It gets repeated hundreds of times, until the original source is forgotten and all is left is a newly fabricated lie, that is easily digestible by uncritical readers. At the end it goes as far as being quoted as an example during legislation debates.
