Thats a hell of a stretch. When have scientists predicted the end of the world? There was the population explosion fear, that third world countries wouldn't slow down their birth rates. There was the ozone layer, but scientists were completely right about that and it had large impacts on affected populations. Increased cancer rates, loss of animal and plant life. There was a brief worry that the atomic bomb might light the atmosphere on fire, but they realized that was wrong pretty immediately.

At worst there was one prediction that was wrong, and that was only because it was based on sociology and psychology. That's not the same as global warming.
