Eugenicists, phrenologists, and Freudian psychologists were scientists too
So what part of the science are you disputing? Do you think CO2 levels are not actually rising/ have nothing to do with human activity? Do you not believe atmospheric CO2 acts as a greenhouse gas in the atmosphere?
There have been plenty of flawed scientific theories throughout history which have been proven wrong, but they weren't proved wrong by somebody saying, "well I dont care what evidence you have, other scientists were wrong before you so I dont believe anything you have to say"
