We are guided by consensus a thousand ways every single day, but it's only climate science where people seem to get bent out of shape.
Because trillions of dollars' worth of economic rewiring is being called for on the basis of climate science.
An environmentally-friendly scientist once said that "Extraordinary claims require extraordinary proof." I've never been a fan of that because at the end of the day, "extraordinary" is just somebody's value judgement. But when objectively extraordinary demands are being made, then it seems like a good time to start demanding extraordinary certainty. The language of consensus is not sufficient, because throughout history there are far too many instances of "97% of scientists" agreeing on things that turned out to be completely wrong.
