There is no particular value in looking for "support" and certainly none in looking for "Consensus" when a scientific question is involved, rather there is simply the evidence and the hypothesis and so forth.
I've simply argued that "climate change math ISN'T easy" and I have pointed out to you that you have not proven "A consensus" in scientific thinking pre 1973 regarding anything.
You've speculated there may have been a consensus. But that's ridiculous, because the associated scientific community was numbered in the thousands or tens of thousands. If all you can show is a dozen or so papers, then these peoples' attention was simply elsewhere.
Regarding your question about whether belief creates a consensus in science, yes they can, but not necessarily. Reference Lysenko, Stalin era. Many examples of this sort of thing.
