CEI Files Formal Complaint Regarding NASA's Claim of 97% Climate Scientist Agreement on Global Warming
Information Quality Act Correction Request Regarding NASA’s Claim that 97 Percent
of Scientists Agree on Anthropogenic Global Warming
In support of its 97% statement, NASA cites five studies; two by John Cook, and others by
William Anderegg, Peter Doran, and Naomi Oreskes. But as shown below, none of these studies
adequately support the claim.
The oldest study cited by NASA is the study by history professor Naomi Oreskes. But as pointed
out below, due to criticism Oreskes had to issue a formal correction. The Doran and Anderegg
studies examined different aspects—a survey and public statements, respectively. However,
those authors acknowledge that these methods cannot determine the overall percentage of
scientist who agree. The Cook study was in many ways an attempt to redo the original Oreskes
study with a broader and more complete scope and without the problem that required formal
correction by Oreskes. Many of the scientists whose papers were evaluated by Cook claim their
research was inaccurately categorized, which raises basic questions about the study’s
reliability.
The paper then added the first three categories together (3,896 papers) and compared that to the
sum of the last three categories (78 papers) plus studies expressing uncertainty (40 papers). In
short, 4,014 papers (3896 + 78 + 40 = 4014), expressed or implied a position on AGW. Of these
3,896 or 97% supposedly affirmed the consensus view. But this was 97% of abstracts of papers
in which a position was taken. But this total did not include the 66.4% of all papers that did not take a position (4a).
In other words, at most, Cook et al. found that about one-third of peer reviewed papers containing the search terms “global warming” or “global climate change”
endorse the consensus viewpoint—a far cry from 97%.
Legates’s peer-reviewed independent study reevaluating the 64 articles that Cook said explicitly
endorsed AGW (that more than half of the warming was caused by humans) found that actually
only 41 made such claims
In other words, according to the Cook team’s own data, only 0.5% of the
papers reviewed support the NASA claim (64 of 11,944). The Cook researchers actually found
more papers skeptical of NASA’s statement than those supporting NASA’s claim.
