Anyone who has studied the history of science knows that many theories that were universally accepted and “known” to be true turned out to be false. See these examples from the Houston Chronicle and the Guardian.

Noam Chomsky said years ago that he would submit to fascism if it would help combat global warming:

Suppose it was discovered tomorrow that the greenhouse effects has been way understimated, and that the catastrophic effects are actually going to set in 10 years from now, and not 100 years from now or something. Well, given the state of the popular movements we have today, we’d probably have a fascist takeover-with everybody agreeing to it, because that would be the only method for survival that anyone could think of. I’d even agree to it, because there’s just no other alternatives right now.”
