A mere 8000 years ago, the Sahara had a semi-arid/deciduous climate with lakes as large (if somewhat shallower) as the Great Lakes.

We first presented this subject at SciTechNature in 11-19-17: "When Sahara Was Green". Since then more research has been forthcoming:

Outrageous heresy, but an animation interesting enough to make the hair on the back of my head stand up:
