Ignoring the irony of your accusation of others being "laughed out of every scientific discussion", Cook et al. (2013) was a reviewed, journal-published paper estimating scientific consensus. The methodology and data were supplied. The team additionally provided a comprehensive DIY tool on Cook's website so that one can reproduce the analysis.

And note that while Cook et al. is the latest consensus paper to be unwarrantedly attacked by rejectionists, there remain many other published papers that have found very similar results. In continuing with this line of questioning the consensus, you are merely beating your head against a wall of consensus. Again, if you had but a bit of familiarity with the science, you would easily see why that consensus exists.
