So pre-industrial period and a drop in human population correlates with a reduction in global temperature.

Population has increased a lot and would be interesting to map that upon global temperature.

However you look at things - humans DO affect the climate of this planet pure and simple.

it is irresponsible to promote this rhetoric

Actually this is due to the slightly "clickbaity" tile... If you had read the article you would easily find it is about:

How is this rhetoric?

It was always obvious that this is one of the solutions to the climate change.

There's your solution to climate change. /s

At this point it should be considered unethical to have more than 1 child per household. I don't care if that's politically incorrect, it's basic math. The entire species needs to drop to below-replacement reproduction. No eugenics, genocide or war required, just stop acting like horndogs or get snipped for Pete's sake.
