The great deserts of Africa will continue as deserts in the Aftertime, as air lifted off the new Equator will curl around and pass over the land now to the south of these deserts before passing over this land, thus will be depleted of moisture picked up over the Atlantic by the time it arrives. This will be the case in particular in Algeria, which have mountains to bump over on the way to the deserts, a known depletor of moisture during such an air lift. In that this is not so much a change as a continuity for Algeria, the people will adjust quickly to the change where the Sun is seen to rise in what had been the South.
