Except it doesn't solely rely on that data. From earlier in the article: "In conducting the study, the agency evaluated more than 3,500 previously published reports, studies and data sources, including articles published in science and engineering journals; and reports by federal and state governments, nongovernmental organizations and industry groups. The agency also conducted additional scientific research, resulting in more than 20 peer-reviewed reports and papers. The draft report will now be made available for public comment and peer review by an independent board of scientists before being finalized."
