Transcript: Ghosts of the Green Sahara

This black wasteland holds the ghosts of a very different past. Between 6 and 10,000 years ago during the African humid period, the Sahara was a fertile savanna. This massive volcanic plateau acted as a natural watershed catching monsoonal rains. The runoff fed ancient river systems and curved deep wadis through the lava emptying into Lake Megafezzan, a vast prehistoric inland sea that once lay to the southwest. Neolithic hunters frequented these volcanic craters using the abundant, highly durable basalt to nap intricate arrowheads and tools. These carvings on the dark walls of the wadis remain as a silent testament to a time when this volcanic field teemed with water, animals, and human life.

“She’s got a liquid-crystal compass
A picture book of the rivers
Under the Sahara...”

This explains the water source for the crocodiles that were mummified by the Egyptians. Everyone thought they were Nile crocs but the DNA was the same as the few crocs that live in the remaining lakes across the bottom of the Sahara.

Good call. I remember seeing an isolated small lake, shaded in a deep gorge in the desert, which had a croc population, no doubt inbred.

the deep question these days is how do we turn the deserts green. Because in order to terraform mars, we first have to figure out how to terraform earth.

The deeper story is that we will have two populations within a hundred years with two increasingly distince futures. 1.)mars/space 2.)earth. Each will need to expand to have a hope and a future. For earth, the answer will be bringing water to the desert because that will roughly double the habitable size of earth.
