“By 7,000 years ago (5000 B.C.) and lasting for about four millenniums, the earth was warmer than today, perhaps by 4 degrees Fahrenheit... Although the climate cooled a bit after 3000 B.C., it stayed relatively warmer than the modern world until sometime after 1000 B.C., when chilly temperatures became more common.” - Stanford

I'll get to cause and effect when I publish.

If a book I want on the list,...sounds fascinating...

First time Man REALLY changed his climate environment.

And it wasn't via emitting CO2.
