Not every reviewer agreed with the IPCC

Here are some snippets from one such reviewer:

General Comments

The idea that climate without human intervention can only undergo “natural variability”, and that “climate change” can only result from human activity is false and fallacious. It is in conflict with all that we know of evolution and geology. It is simply wrong to assume that “ climate change” automatically implies human influence on the climate.

This fallacy is embraced by the Framework Convention on Climate Change, but the IPCC (Footnote to “Summary for Policymakers. Page 1) claim that they are prepared to accept “natural variability” as “climate change”. They are, however, unwilling to accept the truth, which is that climate can change without human intervention

An additional fallacy adopted by the IPCC is the claim that it is possible to “attribute” cause and effect from a correlation. Science can assign probability levels of the likelihood of a cause and effect relationship, but it can never attribute a cause and effect relationship with certainty. This Report does not assign any quantitative probability levels to correlations

There is undue emphasis throughout on the importance of surface temperature trends measured by weather stations. Chapter 2 has 10 diagrams showing these data, but only one thoroughly confusing diagram (Figure 2.12) for other methods of global temperature measurement. The fact that satellite and weather balloon measurements in the lower troposphere do not show a warming for the past 21 years suggests strongly that the surface data are influenced by proximity to human habitation, rather than by greenhouse warming.

The assumed atmospheric concentration figures for carbon dioxide for the SRES scenarios were included in the First Draft, but have now been deleted. Presumably you are ashamed to admit such absurd figures. Figures for all the other gases are given in Chapter 4 including ridiculously exaggerated figures for future methane concentrations.
