text: Projections v. Reality: On his blog, Roy Spencer presents a comparison of the lower atmospheric temperature trends as projected from 44 climate models and as calculated from satellite observations. John Christy provided the model projections. Spencer used the both the University of Alabama, Huntsville (UAH) and the Remote Sensing Systems (RSS) calculations. The disparity is striking. Since the greenhouse effect takes place in the lower atmosphere, this is further evidence that the planet is not as sensitive carbon dioxide emissions as advocated by the UN Intergovernmental Panel on Climate Change (IPCC).
