Yes, and I told them to ask momma about the blizzard of 78.
LOL! I must be older than you because I was a kid and I remember that blizzard VERY well.
Schools were closed for weeks, because snow drifts covered school doors.
Once it was over, our (1970s) teachers kept telling us about the "coming ice age".
I honestly DON'T remember them saying anything about "Man" causing it. It just WAS.
At the time it was considered "nature".
And a teacher telling us it was because we drove cars and used incandescent light bulbs would have probably been fired for being insane, and not fit to be teaching kids.
