Never to be reported on by the "mainstream" left-wing media.
Re: “And it was probably a bit warmer than it is today.”
I recently read that around 9,700 BC ice cores from Greenland show that the average temperature increased by 18 degrees F in just 150 years!
That might explain why forests returned around that same time period to Greenland’s polar neighbor, Norway.
World population estimates for 10,000 BC are less than 1% of today’s population, so man made climate change did not even exist back then.
