Global warming? My thought / questions
If one goes back to say 1960,
How many street lights were there?
How many homes and businesses were there?
How many were air conditioned?
How many humans were there?
How many cars were in the US alone?
What was the average operating temperature of those cars vs today
Don't forget to throw automatic transmissions in there
None had catalytic converters
How big and long (timewise) were the traffic jams in major metro areas compared to today?
How many flights a day did the airlines make?

Now fast forward to 2023 and ask the same questions.
All of the above things generate HEAT along with many other unmentioned sources.
Where does that heat go?

I'll be interested to the responses as it is something I've wondered for a long time
