Two points, the Little Ice Age didn't end until 1850, there were quite a few humans around at that time.yes the planet has warmed up after the last ice age or the USA would still be covered in ice.........LOL
But man was not around when the planet started re warming..........LOL
Man was around long before the last ice age started.
"The Last Ice Age cycle lasted from roughly 60,000 to 20,000 years before present"
"The first Homo sapiens, descendants of H. rhodesiensis, appeared in Africa about 250,000 years ago."
Do you know anything worth knowing?
