Yes, and back in the 1970's, a "decent amount of opinion in the scientific community" told us that we were heading into another ice age, and that we would overpopulate the planet and starve to death about, oh, 10 years ago...
That was based primarily on some media overhype and had very little scientific basis. I can give you references on that if you want. Aw heck: Was an imminent Ice Age predicted in the '70's? No explains it well.
