Those who deny that humans are responsible for today’s changing climate are admitting is that their cause has no scientific basis, because, if it were, they would not be last ditch defending the inclusion of fourth raters in the Wikipedia. There is nothing these clowns (and Eli uses the word with purpose) have beyond their ostrich act.
The Weasel brought one case to attention, a Marcel Leroux, a very minor French academic, who whose article was deleted in the Wikipedia and my, did that get the Willard Tony crowd excited,
but of course, everything gets them excited. The convoluted theory of why Leroux and similar deserve a Wikipedia page devolves to that they are contrarians, equivalent to praising those whose opinion differs that the Earth is a spherical object. Although bound up in Wikiadministrivia (Stoat is an expert practicioner ) the discussion of whether to relist captures the full flavor.
Now Eli observed with amusement the push starting four or five years ago to get actually denialist papers published here and there. Some of those attempts, have, of course not ended well. Others have simply vanished into the ether. Rumors abound about a coming reprise of the Oregon ISM, NIPCC type to appear under the auspices of the Cato Institute as a response to Climate Change Impacts in the United States . We shall all enjoy another attempt to put lipstick on a pig, dressing it up as something other than a press release from a think tank
Part of this push was to come up with enough losers to establish a beach head in the Wikipedia, which has become a de facto first stop in looking things up. No one is going to object if someone like Lindzen or Roy Spencer (a weaker case) has an entry but there really is some weak wood out there waiting to be cut out. The bench on the denialist side is full of splinters.
