Kevin Trenberth, an advisor to the UN's Intergovernmental Panel on Climate Change (IPCC), made some startling admissions regarding the IPCC's use of computer General Circulation Modules (GCMs) (h/t Moonbattery). Professor Bob Carter, a geologist writing for Australia's News.com, has the scoop:
In a remarkable contribution to Nature magazine's Climate Feedback blog, Trenberth concedes GCMs cannot predict future climate and claims the IPCC is not in the business of climate prediction. This might be news to some people.
Among other things, Trenberth asserts ". . . there are no (climate) predictions by IPCC at all. And there never have been". Instead, there are only "what if" projections of future climate that correspond to certain emissions scenarios.
You do remember that the IPCC has been leading the charge with Al Gore on the whole "scientific consensus" on man-made global warming.
Carter also relates that in a paper to be presented at the 27th International Symposium on Forecasting in New York this week, Scott Armstrong and Kesten Green find other discrepancies within the relevant chapter in the IPCC's latest report.
