The latter half of the 1970s was weird, at least in the East.
There were a number of Bermuda Highs that made life miserable, especially for MLB pitchers that couldn’t keep up the pace in 90F+ temps in NYC and Boston.
Then there was the Blizzard of 1978 that hit the Northeast.
And sustained cold that froze pipes, set or met records for number of days total and continuous, for being at or below freezing, at or below 0F, etc.
Oh, and solar activity was blamed for bringing down Skylab earlier than predicted due to drag from an expanded atmosphere.
If we get bad winters like the late 70’s again a lot of people are going to be in rough shape. The heating equipment back 40 years ago was a lot more reliable than all this electronic crap they put out today. Lot’s of luck getting parts to heat your house.
