“The fact of the matter is that there does exist a growing body of scientific evidence that the climate changes in the coming decades will be modest and proceed at a rate that will lie somewhere near the low end of the IPCC projected temperature range.”
Paul Knappenberger

The claim by the IPCC that an imposed climate forcing (such as added atmospheric concentrations of CO2) can work through the parameterizations involved in the atmospheric, land, ocean and continental ice sheet components of the climate model to create skillful global and regional forecasts decades from now is a remarkable statement. That the IPCC states that this is a ‘much more easily solved problem than forecasting weather patterns just weeks from now’ is clearly a ridiculous scientific claim.

The IPCC WG1 Chapter 3 Report clearly cherrypicked information on the robustness of the land near-surface air temperature to bolster their advocacy of a particular perspective on the role of humans within the climate system. As a result, policymakers and the public have been given a false (or at best an incomplete) assessment of the multi-decadal global average near-surface air temperature trends.

Humans are significantly altering the global climate, but in a variety of diverse ways beyond the radiative effect of carbon dioxide. The IPCC assessments have been too conservative in recognizing the importance of these human climate forcings as they alter regional and global climate. These assessments have also not communicated the inability of the models to accurately forecast the spread of possibilities of future climate. The forecasts, therefore, do not provide any skill in quantifying the impact of different mitigation strategies on the actual climate response that would occur.
Roger A. Pielke
[W]e shall find a very material difference between the body and the spirit; the body is supposed to be organized matter, and the spirit, by many, is thought to be immaterial, without substance. With this latter statement we should beg leave to differ, and state the spirit is a substance; that it is material, but that it is more pure, elastic and refined matter than the body; that it existed before the body, can exist in the body; and will exist separate from the body, when the body will be mouldering in the dust; and will in the resurrection, be again united with it.
Joseph Smith
The role of urban areas within the climate system is yet another human climate effect whose role was minimized in the 2007 IPCC WG1 Report.
