You know one of the key differences between science and religion? Theories are changed/developed in the face of empirical, experimentally reproducible evidence. If we learn we were wrong about something, we change our practices to match our new knowledge of reality. That’s why smoking is discouraged and even outlawed in some places. That’s why we limit lead exposure now. The people who don’t have their heads buried in their own asses are very much aware fossil fuels are contributing to climate change.
There was never a consensus that lobotomies were an appropriate treatment for anything. I don’t know whose crusty asshole you pulled that shit out of. (Source: my psych degree, I actually studied this shit.)
You seem to be under this blatantly wrong assumption that “scientific consensus” means anyone in a white coat is an infallible member of the priestly caste.
