Scientists who responded to the doran/zimmerman survey had this to say;
“..I did complete your survey. However, no matter how important, no matter how apparently obvious the combination of facts and theory, scientific issues cannot be decided by a vote of scientists. A consensus is not, at any given time, a good predictor of where the truth actually resides..” (Zimmerman feedback)
“..Science is not based on votes or consensus. Irrelevant question. Besides, which scientists do you regard as relevant?..” (Zimmerman feedback)
“..Science is based on scepticism and experimental proof. Whereas human GHG emissions certainly have a warming effect, the breakdown between natural and anthropogenic contributions to warming is poorly constrained..” (Zimmerman feedback)
Consensus is not science, you should know this.
