if they start taking the sahara sand it'll turn into a lake.

  And? - Extract lots of sand - Fill it with water Maybe it will compensate for the increased ocean levels if the hole is big enough

    It's more complicated, and someone thought about a similar project with a different objective: "Qattara Depression Project "https://en.wikipedia.org/wiki/Qattara_Depression_Project https://en.wikipedia.org/wiki/Qattara_Depression_Project Edit: Also see "Flood Death Valley" https://what-if.xkcd.com/152/ https://what-if.xkcd.com/152/

      That much evaporation is going to increase rainfall downwind. If the Sahara keeps spreading we might have to do that project for several reasons. Edit: aaand it’s full of cheetahs and gazelles. Damnit.

    - Extract lots of sand [from the desert] - Fill it with water - Run solar distillation - Create additional freshwater source for region (at expense of creating a high-salinity lake)

      it won't need filling, it'll come in from the nile or mediterranean or make the mediterranean larger but shallower.

  Good solution for desertification: just remove the desert.
