Possible solution to eliminate hurricanes?

[Fake Messiah]

So all the hurricanes come from the same place, West Africa, and are caused by the clash of hot dry air over Sahara and cool moist air above oceans as well as the hot dry air from Sahara and cooler wetter region in the south




So the solution would be to make Sahara green, wet and cooler. Back at the beginning of XX. century American inventor and engineer Frank Shuman started with greening Sahara by using solar thermal power but then ww1 came and all his stuff was melted to be made into guns. Now it could be still done today but who is going to organize it?

These are screencaps from 2014 "Cosmos" series episode "The World Set Free" of how to green Sahara.

Temporary "solution". The farms in the Imperial Valley are suffering from salt build-up and won't be usable in a few decades.

Imperial valley is a geological sump.  The only way water that goes in can ever leave is by evaporation, leaving behind all the mineral and salt content the water had when it first flowed in.   Hence salt build up. Large parts of Mohave desert in CA, almost all of Nevada, parts of Utah, and Arizona are like that also. Hence all the big dry lake beds in these regions gleaming with salt. Irrigation in these regions inexorably killed the soil.

Sahara hosted large rivers that discharged eventually into the Mediterranean within the last 10000 years, before it deserfied.  So at least parts of Sahara is well drained.  This means water brought in also flushes mineral and salt down stream into the Mediterranean.  So salt build up ought not become an insurmountable problem.

So this solution is in an intenable position. Those who are nominally most concerned about addressing the problem this solution is designed to address would reflexively dismiss this solution as being "Too much human impact".

Eliminating hurricanes would make the equatorial regions uninhabitable. Hurricanes are nature's way of maintaining thermal equilibrium. They transfer heat from the equator to the poles.

The water that evaporates will leave all it's minerals behind. The water that doesn't evaporate will leave some portion of its minerals behind. Drainage just delays the inevitable.

BTW, did you notice that all those river beds are under sand dunes?

The theory that all water create net deposition of minerals would apply to all farming, not just in Sahara. But luckily it is not always true. Initially all water deposited some minerals, but they also dissolve and carry away existing minerals. If there is through flow of water eventually an equilibrium will develope where the rate at which incoming water deposits minerals will be matched by the rate at which water already in the region willl dissolve existing mineral and carry it away. When that equilibrium is establish mineral and salt buildup stops.

The fact that previous river beds are under sand is no big obstacle. The fact that these riverbed exist at all indicates the overall topography facilitates drainage to a lower point outside the region. If sufficient water is delivered into the region again, erosion should clear out the blocked river beds in a few years and the pre-existing drainage pattern will reestablish itself.

Geological evidence shows natural drainage pattern over large regions are surprising durable. Existing Drainage patterns in areas not immediate impacted by large scale mountain building or volcanic activity can often be traced back with little change over tens of millions of years, over repeated cycles of wet periods and periods of deserfication.
