When I was in grade school, all the talk was that another Ice Age was imminent. That was a 'fact' and we could do nothing about it.
Whew!
I guess we dodged THAT bullet.
But then again we used to have 'bomb drills' that consisted of marching out of your classroom and into the hall, putting one forearm in front of your head, the other behind your head and leaning forward against the wall.
This maneuver was meant to protect you from a nuclear blast in case of attack (back in the 50s.)
