IPCC as a political organization

without comments

Green and Armstrong’s paper “Global Warming: Forecasts by Scientists versus Scientific Forecasts,” found that the IPCC reached its conclusions about global warming despite the lack of a single scientific forecast. How could scientists do this? Tim Ball, an eminent climatologist, explains that the IPCC process was political rather than scientific in his article “How UN structures were designed to prove human CO2 was causing global warming.” An excerpt is available below.

The IPCC is a political organization and yet it is the sole basis of the claim of a scientific consensus on climate change. Consensus is neither a scientific fact nor important in science, but it is very important in politics. There are 2500 members in the IPCC divided between 600 in Working Group I (WGI), who examine the actual climate science, and 1900 in working Groups II and III (WG II and III), who study “Impacts, Adaptation and Vulnerability” and “Mitigation of Climate Change” respectively…They accept without question the findings of WGI and assume warming due to humans is a certainty. In a circular argument typical of so much climate politics the work of the 1900 is listed as ‘proof’ of human caused global warming. Through this they established the IPCC as the only credible authority thus further isolating those who raised questions.

The manipulation and politics didn’t stop there. The Technical Reports of the three Working Groups are set aside and another group prepares the SPM. A few scientists prepare a first draft, which is then reviewed by governments and a second draft is produced. Then a final report is hammered out as a compromise between the scientists and the individual government representatives. It is claimed the scientists set the final summary content, but in reality governments set the form. The SPM is then released at least three months before the science report. Most of the scientists involved in the technical or science report see the Summary for the first time when it is released to the public. The time between its release to the public and the release of the Technical Report is taken up with making sure it aligns with what the politicians/scientists have concluded. Here is the instruction in the IPCC procedures. “Changes (other than grammatical or minor editorial changes) made after acceptance by the Working Group or the Panel shall be those necessary to ensure consistency with the Summary for Policymakers (SPM) or the Overview Chapter.” Yes, you read that correctly. This is like an Executive writing a summary and then having employees write a report that agrees with the summary.
