Same series, episode named "Sahara Info" discusses the emerging evidence that the Sahara goes through 20,000 yr cycles of fertile/desert/fertile. Seems the earths wobble causes the tilt of the axis to shift on a regular basis is the working hypothesis. Cycle has been confirmed going back 3 million years. Basically earth rocks! Naturally the axis shift does affect the whole planet. So much for man made global warming.
