Brulle claimed to expose a network of nonprofit organizations executing “a deliberate and organized effort to misdirect debate and distort” the public’s understanding of climate science. In our examination of Brulle’s claims, CRC closely examined his list of 91 organizations for 2010, the most recent year he studied. To determine the degree each group focused on climate issues, we considered IRS filings; organizations’ profiles by the news media and opposition-research organizations; mentions in the Lexis-Nexis news database and on the Web as reported by Google; and the groups’ own websites, annual reports, and other publications.
