Global Energy, GWP and Population Growth: what happened in 1972?

[Iterate]

3. Beats me.

I've never thought about the growth rate of those three that way.

50 years after WWI, 25 after WWII? I know wars can have some serious knock-on effects that keep echoing. It's also about the same time that rebuilding after WWII was largely completed. If that's part of it, similar numbers for China should be shifted later by about five years, because it ended later for them and they had the famine from '58 to '61.

It's also about the time full employment ended world-wide. Cause or effect?

Energy and WDP were far more linked then, so you might be counting the same activity twice. Maybe??

Or it was because the Beatles broke up. That, and the near certainty that if you write a book called "The Population Bomb" you will learn on the publication date that the growth rate had already peaked.
