While I may agree with certain statements made by the IPCC, surely you and the Royal Society would respect my right to disagree with other statements or at least to call them into question.You can read the news report on Moore's statement here, and further comment on the Royal Society's squelching (posted here at 'Not PC' on Monday) from George Reisman.
You cite the IPCC as the authority yet surely you are aware that science does not work by committee or by "consensus."
Certainly the Royal Society would agree there is no scientific proof of causation between the anthropogenic increase in atmospheric CO2 and the recent global warming trend, a trend that has been evident for about 500 years, long before human-caused increase in CO2 was evident.
I am sure the Royal Society is aware of the difference between an hypothesis and a theory. It is clear the contention that human-induced CO2 emissions and rising CO2 levels in the global atmosphere are the cause of the present global warming trend is an hypothesis that has not yet been elevated to the level of a proven theory. Causation has not been demonstrated in any conclusive way.
