Total of 11,944 papers written by 29,083 authors and published in 1,980 journals
97.1% endorsed the scientific consensus when presented with an abstract on AGW.
the average numbers of authors per endorsement abstract (3.4) and per no positions abstract (3.6) are both significantly larger than the average number of authors per rejection abstract (2.0)
A direct comparison of abstract rating versus self-rating endorsement levels for the 2,142 papers that received a self-rating is shown in table 5.
Discussion
Of note is the large proportion of abstracts that state no position on AGW.
process of determining the level of consensus in the literature contains sources of uncertainty
issue of representativeness was addressed by selecting the largest sample to date for this type of literature analysis
sample has those surveyed by Oreskes and Schulte.
539 'global climate change abstracts' from jan '04 to jan '07 found 45% endorsement and 6% rejection.
Conclusion
the public perception of a scientific consensus on AGW is a necessary element in public support for climate policy.
consensus gap campaigns are confusing to the public.
