To quote John Reisman, “Science is not a democracy. It is a dictatorship. It is evidence that does the dictating.” It’s this evidence based ‘dictatorship’ that is the basis for a scientific consensus. Based on this ‘dictatorship’ of evidence we know that global warming is real, we’re causing it, and that it’s a problem if we don’t act. This presents a real problem for those denying that there is a problem or want to minimize the consequences.
