Investigative Summary Regarding Allegations that NASA Suppressed Climate Change Science and Denied Media Access to Dr. James E. Hansen, a NASA Scientist [open pdf - 3MB]
"On September 29, 2006, 14 United States Senators cosigned a letter to the NASA Inspector General to request a formal investigation into allegations of 'political interference' with the work of scientists at NASA. In particular, the letter conveyed the Senators' concern with apparent and 'repeated instances of scientists . . . having publication of their research and access to the media blocked, solely based upon their views and conclusions regarding the reality and impacts of global warming.' The letter also identified areas of specific concern coupled with a request for this Office 'to conduct a full and thorough investigation into the suppression of science and censorship of scientists at [NASA].' Accordingly, the NASA Office of Inspector General conducted an administrative investigation to examine reports of alleged 'political interference,' predominantly by senior NASA Headquarters Office of Public Affairs officials, with the work of NASA scientists pertaining to climate change-to include whether NASA inappropriately prevented one of its scientists, Dr. James E. Hansen, from speaking to the media in December 2005. Our investigation found that during the fall of 2004 through early 2006, the NASA Headquarters Office of Public Affairs managed the topic of climate change in a manner that reduced, marginalized, or mischaracterized climate change science made available to the general public through those particular media over which the Office of Public Affairs had control (i.e., news releases and media access)."
