Would that be the 'Nobel prize winner' Dr Mann, who massaged the so-called hockey stick data leading to all this climate change/global warming hysteria in the first place? Hardly a credible source of anything IMHO.
Dear oh dear. Using Wikipedia to support Climate Change denial denial? Ignorance is bliss I guess. This is a good overview I picked from a random search of the many issues with Mann's work re the Hockey stick, and his lack of professional integrity [1], which is even hinted at in the well-scrubbed Wikipedia page. Anyway there's a ton of easy-to-find extremely well-sourced information debunking the stick.
By the way, Mann was forced to stop calling himself a 'Nobel Prize recipient', after it was found out that he wasn't directly awarded the prize; it was awarded to the IPCC.[2]
