This is the kind of thing I frequently point out to people in debates about global warming. How often do we see news items where scientists are surprised at some new discovery that “turns everything we thought we knew on its head?” Therefore, how can there be such a things as “settled” science, or a “consensus?”
Part of that is coverage, i.e., straw men, the rest is careerism. Science is a method, not a body of knowledge.
There can't be. Science is open-ended and new discoveries or evidence can change a theoretical model in an instant. Consensus is a term that should never be applied to the scientific method.
