By flooding the Qattara depression in Egypt, you could get plenty of hydro power and rain clouds over large parts of the Sahara.
All it would take is a long canal, nothing outside our capabilities.
- pier25 7y agoIs that actually feasible? Not the canal, but the modification of the climate.
- sdfAcasf 7y agoLocally, absolutely. In this case most of the evaporated moisture would fall within a certain distance of the artificially created lake. Some of the moisture would escape and fall into the sea, but that's fine because it was sea water to begin with (unlike an artificial sweet water lake near the sea) Globally with a non-desired negative consequence? It seems like it. GHG -> Climate change Globally with a specific desired goal? Not so obvious, but some people have made interesting proposals: - Melting the Artic Ocean by enlarging the Bering strait. - Reversing sea rise by damning the Bering Strait. - Capturing CO2 by dumping Fe into the oceans. - Lowering global T by emitting SO2, - Terraform the Sahara into a tropical jungle reversing desertification (once there are plants, more moisture would be retained) - And others Notice how they all have potentially catastrophic side-effects.
