Intentionally radically altering the climate of large areas like the Sahara seems very dangerous in a way that nothing that could be done on other celestial bodies could ever be. Not that it shouldn’t be considered, but I think it calls for a far greater degree of caution than e.g. experiments to bring life to small domed areas of the surface of Mars.
