You know, I don't know what is worse - being ignorant of geology, anthropology, oceanography and history, or calling this transparent fraud "science".
100 000 years ago, my home was in a savanna. 10 000 years ago, it was under two miles of ice.
Before humans did anything of consequence, temperatures rose 18-20 degrees Celsius, all that ice melted, and the oceans rose 400 feet.
To believe that trivial (if they even exist at all) late temperature variations are human induced, while all those massive historical changes occurred on their own is just, just - IGNORANT.
The Younger Dryass is Not part of the primary period of maximum glaciation (core of the Ice Age). it's a separate anomaly.
BTW, we are currently 5,000 years overdue for the next big one.
Regarding previous knowledge of ice ages, ice cores from Antarctica reveal we've had 20 big cycles in the last 2.5 million years ~ with global impact!
On the other hand, Antarctica has been credited with being ice covered for the last 5 to 7 million years.
More recently they've been studying a mountain range that's under 2 miles of ice, and it turns out some of that ice down near the mountains may be anywhere from 280,000,000 to 500,000,000+ years old.
That is, some Antarctic ice may date all the way back to the days of the last "Snow Ball Earth" episode.
Basically, that means "Snow Ball Earth" didn't really end, and plenty of Ice and Snow is a very normal situation on this planet. Toasty and warm isn't normal and will not last.
