I have toyed with the idea of climate change causing the African monsoon to go all the way up to the Mediterranean coast in the next few decades. The Qattara depression would start filling and maybe have a very interesting years of swamp-like conditions. But the erosion in the Nile delta and surrounding areas would be a slow--but not slow enough--catastrophic event for Egypt.<p>It would be interesting to see what climate change models forecast for the region.
