The EPA Administrator must view the IPCC’s claims with considerable skepticism. The IPCC’s findings are flawed, biased and unproven. The implied level of “endorsement” by scientific participants in the IPCC–process is not supported by the data. The international standards of independent refereed peer review have not been met by the IPCC. Thus, EPA should not rely on the IPCC reports for its proposed Endangerment Finding and the Technical Support Document.
