In 2008. a group og world renowned scientists descended on the UN to claim that man-made global warming was a crock.
That made news for about two days.
Famed geochemist, Claude Allegre, a card carrying Socialist and one of the original man-made global warming advocates did A 180 on the issue.
He eventually said that 'it is not about politics. it is not about religion. it is about science, and the fact is that there is no proof that man has been the cause of the recent global warming.'

"Allègre states that the causes of climate change are unknown. This represents a change of mind, since he wrote in 1987 that "By burning fossil fuels, man increased the concentration of carbon dioxide in the atmosphere which, for example, has raised the global mean temperature by half a degree in the last century"."
In an article entitled "The Snows of Kilimanjaro" in l'Express, a French weekly, Allègre cited evidence that Antarctica's gaining ice and that Kilimanjaro's retreating snow caps, among other global-warming concerns, can come from natural causes. He said that "[t]he cause of this climate change is unknown".
Allègre has accused those agreeing with the mainstream scientific view of global warming of being motivated by money, saying that “the ecology of helpless protesting has become a very lucrative business for some people!”
The ensuing attacks on Allegre is similar to the defaming of the 31,000 American scientists who say man-made global warming is a crock.
