What if the Pleistocene ice caps/landmasses survived?
Hi, i was thinking about making a scenario where Northern Africa/the Middle East have a colder climate (and etc for the rest of the world) so the groups that settle there become the dominant world powers (like Europe of otl) and would this be possible if the Pleistocene ice caps stayed? first, can they say, and if so, can the landmass “shapes” survive but just some of it can just become very cold (not ice caps) (sorry for vague wording, not a geography expert lmao). And would this have the desired effect, as civilisation centres a little further south than otl. and how would this effect the rest of the worlds climate and such. Thanks
