After the 300 yrs. of the 'Little Ice Age', the climate returned to normal in as little as one decade. The next ice age could come like a thief in the night.
Has anyone noticed that your hottest days come in advance of a cold front?
In the sixties and seventies it was global freezing. Remember how most of Canada would be under an ice sheet twelve months a year by 2000? Forgot huh? Then there was the Population Bomb that was going to go off around the year 2000. The world would run out of food.
Both of these crises NEEDED big government to avert the end of the world. Remember?
People have such short memories.
