This “challenge” of a warming climate led to the agricultural revolution, settlements then cities, and civilization with spare time for such things as creating writing systems.
Men adapt and create.

As I just said, while the tundra steppe was returning to forest, people thousands of miles away in the Middle East, Nile Valley and central China were starting to plant crops and domesticate animals...
I’m glad it happened.
Still, imagine hunting mammoth and woolly rhinos with a Weatherby Mark V SBGM!
They’d make a totem pole with your likeness on it!
