#1 I can't imagine anything more horrifying, any greater threat to humanity, than the possibility of plants growing in a desert. Funny thing though, the hippopotamus appears in ancient Egyptian art and mythology. But hey, maybe they had desert hippos back then.

#2 I'm working off memory here and not the Sahel but the Sahara.... The Sahara has something like a 20,000 year cycle. At one point it was like the Everglades. You can see this in cave paintings. Right now it's at the peak of the dry cycle so without interference it will be peak of wet in 10,000 years. What happens is the wet winds from the Indian Ocean switch back and forth from the Congo latitudes to the Cairo ones. When the Sahara is wet Arabia is too.
