In the IAC Report released today, Working Group II comes in for particular criticism. Working Group II assesses the vulnerability of socioeconomic and natural systems to climate change, negative and positive consequences of climate change, and options for adapting to it. The vindicates what I have been saying, that the worst of climate alarmism comes from the climate effects people.
For fabricating evidence:
The Working Group II Summary for Policy Makers has been criticized for various errors and for emphasizing the negative impacts of climate change. These problems derive partly from a failure to adhere to IPCC’s uncertainty guidance for the fourth assessment and partly from shortcomings in the guidance itself. Authors were urged to consider the amount of evidence and level of agreement about all conclusions and to apply subjective probabilities of confidence to conclusions when there was high agreement and much evidence. However, authors reported high confidence in some statements for which there is little evidence. Furthermore, by making vague statements that were difficult to refute, authors were able to attach “high confidence” to the statements. The Working Group II Summary for Policy Makers contains many such statements that are not supported sufficiently in the literature, not put into perspective, or not expressed clearly. When statements are well defined and supported by evidence—by indicating when and under what climate conditions they would occur—the likelihood scale should be used.
For using unpublished and non-peer-reviewed sources:
An analysis of the 14,000 references cited in the Third Assessment Report found that peer-reviewed journal articles comprised 84 percent of references in Working Group I, but only 59 percent of references in Working Group II and 36 percent of references in Working Group III (Bjurström and Polk, 2010).
