British news organizations are now combing through the IPCC reports, finding more errors and material sourced to non-peer-reviewed material, including student papers and reports by advocacy organizations. Most of these errors continue to relate to the more policy-oriented aspects of the IPCC reports — practical consequences of climate change and potential policy responses. This is further evidence that the more IPCC sought to make its reports relevant to policy-makers, the less reliable the reports became.
UPDATE: According to the Telegraph, former IPCC head Robert Watson believes the IPCC will lose credibility if it does not address its mistakes.
