Why Should We Believe Them Now?

DarkSyde dissects and debunks the rightwing talking point (a "zombie lie") that "In the 70s, all the scientists were predicting a new ice age, so why should we listen to them now?":

For a few years, back in the 70s, the Ice Age claims took on a life of their own and echoed around in a subset of pop culture. Eventually reality and observation caught up to and killed it. It lay mostly dormant for thirty years until, a few years ago, the old story was lovingly exhumed by industry and right-wing PR hacks, and jolted dramatically back to life. It lives today only as a zombie lie in the heads of doubters, near impossible to kill, no matter how many times it's put down.
