I read about it once. I think it was up to medieval times where sahara had lots of green batches and oasis? Though thats in the range of natural climate change.
Btw. most Alpine passes were unpassable from 900 to 1300, we had a mini ice age then.
Nah, green Sahara ended pretty early in the bronze age. The old kingdom Egyptians were really just getting the tail end of it. It was definitely natural, I don't think that's in question; the (non-mini) ice age was simply ending, about on schedule. It would have been a much slower change than what's happening now.
There were a few trees that managed to hang on in one area, though, with the last being "accidentally" run over by the colonial-era French.
