It’s not a popularity contest.Your failing here is your implication that there exists some sort of significant plurality of scientific opinions on this topic. The number of scientists who reject the idea that human GHG emissions are the primary cause of the warming observed since 1850 represent less than 1% of the world's climate scientists. That is not a plurality. That is a gnat floating in a 2-liter jug.
The very idea that science best expresses its authority through consensus statements is at odds with a vibrant scientific enterprise. Consensus is for textbooks; real science depends for its progress on continual challenges to the current state of always-imperfect knowledge. Science would provide better value to politics if it articulated the broadest set of plausible interpretations, options and perspectives, imagined by the best experts, rather than forcing convergence to an allegedly unified voice” (Sarewitz 2011)
