Umm so it doesn’t get cold in Nepal, Tibet, Bhutan, the Gobi Desert, Northern China, etc.?

I have no idea how it plays between northern and southern Europe but there’s no way that the cold environment has anything to do with this it gets equally as cold if not colder in some parts of Asia. Plus many of those places don’t have the abundance of resources that would be provided by the forests or coasts of Northern Europe.
