At any rate...Here is a resource I found for the Saharan topographic features:http://www.pbs.org/wnet/africa/explore/sahara/sahara_topography_lo.htmlThe "Regs" and "Chotts" of the Sahara make up over 70% of it's landmass. Regs are the remains of inland waterways and seas. Chotts are more localized depressions where the sparse rainwater collects and then evaporates. Re-flood those and I'll bet the region would re-bloom. And as it does so it will undoubtedly suck in heat from the atmosphere as it converts liquid water to vapor/clouds. It would be like giving the earth a swamp-cooler as it adds more rain to the Sahara and there for more greening. As the greening picks up, the sands would stabilized and thin topsoils would begin to form. In regions where one would want agriculture, deep-rooting sand-tolerant legumes and so on could be planted to regenerate fertility as they die off and contribute organic material to the soils. As the savannah that was there just a few short thousand years ago returns, I could see huge new wildlife regions opened up to regenerate african species that are being hedged out of their habitats by human invasion. I could see agriculture not only helping to feed people but also contributing to sucking CO2 out of the atmosphere. I could see vast solar farms, saline thermal inversion pond generators, new work, new settlements and so forth. And all this made possible by simply flooding old lowlying areas there with seawater. It's not like Holland, Venice and New Orleans would shed too many tears about shunting some of it in there..lol..
