These emails revealed the ‘sausage making’ involved in the IPCC’s consensus building process, including denial of data access to individuals who wanted to audit their data processing and scientific results, interference in the peer review process to minimize the influence of skeptical criticisms, and manipulation of the media. Climategate was quickly followed by the identification of an egregious error involving the melting of Himalayan glaciers. These revelations were made much worse by the actual response of the IPCC to these issues. Then came the concerns about the behavior of the IPCC’s Director, Rachendra Pachauri, and investigations of the infiltration of green advocacy groups into the IPCC. All of this was occurring against a background of explicit advocacy and activism by IPCC leaders related to CO2 mitigation policies.
