Maybe not so simple. Deserts have in recent years been discovered as possibly
a huge carbon sink that has been soaking up atmospheric CO2 and storing it as
inorganic carbon (both in soil and in ground water). How will flooding with
sea water affect that? See:
Hi Maggie
The level of the water table under the Sahara is very low. The water is
already very saline. The porosity of the rock is enough to take about 2
metres from all the oceans. Water flows down hill so 'all you need' is
a sloped tunnel from the oceans and solar-powered desalination
Flooding the Sahara is a sustainable geoengineering compared to some others; it
could be implemented along some GeoMIP scenarios. I mentioned it during a
workshop in Colorado last July : could some GeoMIP Simulations take into
account this aspect?

Diking and flooding tropical deserts, primarily the Sahara, might:
- Isolate some seawater.
- Allow more sealife/mariculture, and thus, perhaps
- fix more carbon from air via life.
