That's right , 97% of 33%
see: Quantifying the consensus on anthropogenic global warming in the scientific literature
The real question is ,how many papers qualified under level 1 of the 7 levels of endorsement
answer : 65
see: https://thelogicofscience.com/2015/09/08/yes-there-is-a-strong-consensus-on-climate-change/
"Addendum 13-11-15: Several people have been critical of both Cook et al. and my assessment of that paper because Cook et al. only found 65 papers which explicitly stated that humans are causing 50% or more of the warming. "
Even claiming 33% is being really generous.
