A few decades ago, scientists were saying black people had lower iqs and shit.
Indeed. And scientific learned to question their own belief system and stopped taking this seriously.
Not really the best argument here buddy, you are just showing here that science, contrary to your point of view, is a field that tends to allow a better self-reflexion than any other domain.
If you trusted science as a method, you wouldn't be on this side of the political spectrum and you would be actively listening to social sciences. You do none of that, and you are literally questionning climate change and thus the scientific consensus.
Really, not the best move.
While we will have a bit of time before an underwater Texas, I don't think you realize just how serious and dramatic climate change will be and already is for the economy, for the population, for the ressources etc.
