The document is a request by the Competitive Enterprise Institute (CEI) to the Director of the Office of Science and Technology Policy (OSTP) to cease dissemination of the National Assessment on Climate Change (NACC) pursuant to the Federal Data Quality Act (FDQA). It summarizes CEI's previous litigation against the production of NACC. It argues that NACC violates FDQA requirements for objectivity, utility, and reproducibility because it relies on computer models for predictions that are not verified by observed temperature data. It requests that OSTP immediately cease dissemination of NACC in any form.
