97%

“Quantifying the Consensus on Anthropogenic Global Warming in the Literature: A Re-analysis,” by Richard S.J. Tol.  Energy Policy, Volume 73, October 2014, Pages 701–705 

Abstract

A claim has been that 97% of the scientific literature endorses anthropogenic climate change (Cook et al., 2013. Environ. Res. Lett. 8, 024024). This claim, frequently repeated in debates about climate policy, does not stand. A trend in composition is mistaken for a trend in endorsement. Reported results are inconsistent and biased. The sample is not representative and contains many irrelevant papers. Overall, data quality is low. Cook׳s validation test shows that the data are invalid. Data disclosure is incomplete so that key results cannot be reproduced or tested.

P.S.  Yet the paper by Cook et al is the reference for the claims by Obama, Gore, UN, EPA, et al that 97% of climate scientists agree.  Dr. Tol is a proponent of AGW and is one of the scientists who were misquoted by Cook et al.
