A review by the IPCC of its earlier reports has admitted that the manner in which the reports were produced had serious problems and fundamental biases.

The IAC reported that IPCC lead authors fail to give “due consideration … to properly documented alternative views” (p. 20), fail to “provide detailed written responses to the most significant review issues identified by the Review Editors” (p. 21), and are not “consider[ing] review comments carefully and document[ing] their responses” (p. 22). In plain English: the IPCC reports are not peer-reviewed.

The IAC found that “the IPCC has no formal process or criteria for selecting authors” and “the selection criteria seemed arbitrary to many respondents” (p. 18). Government officials appoint scientists from their countries and “do not always nominate the best scientists from among those who volunteer, either because they do not know who these scientists are or because political considerations are given more weight than scientific qualifications” (p. 18). In other words: authors are selected from a “club” of scientists and nonscientists who agree with the alarmist perspective favored by politicians.

The rewriting of the Summary for Policy Makers by politicians and environmental activists — a problem called out by global warming realists for many years, but with little apparent notice by the media or policymakers — was plainly admitted, perhaps for the first time by an organization in the “mainstream” of alarmist climate change thinking. “[M]any were concerned that reinterpretations of the assessment’s findings, suggested in the final Plenary, might be politically motivated,” the IAC auditors wrote. The scientists they interviewed commonly found the Synthesis Report “too political” (p. 25). [emphasis mine]

The sad part is that almost none of these problems have been addressed by the IPCC in producing its next report, due out sometime in 2013 or 2014.
