Wonder what the effect of billions of gallons of salt water seeping into the aquifer would have on it.

Isn't the main obstacle to creating an inland sea in the Sahara, the long term salination of the water body? The one way flow of sea water into the inland sea would result in increasing concentration of salt, until you end up with a body of water so saline that it is good for nothing. Like the Dead Sea. However, if they could build a sea which has a steady flow of water in and out, thereby ensuring proper oxygenation and no more than normal sea levels of salt. That would be a project worth pursuing.

Probably not, depending on how wide the canal is. The Mediterranean itself is a closed body of water with a relatively narrow inlet, but there's enough exchange between it and the Atlantic that it's only slightly more saline, more so in the east than the west and more in the summer than at other times. And depending on how the sea influenced the climate in the area, there might be increased inflow of fresh water from new rivers. The Dead Sea, by contrast, is fed ONLY by the Jordan and cannot possibly send any water upstream.

There is no change to rainfall when it is full vs empty, despite 10mms of evaporation a day for months over a 10,000km square area (far bigger than the Sahara proposals). There is some low level evidence that Lake Eyre may have a slight impact on rainfall levels in New Zealand when it hits their mountains, 3,600kms away but it certainly doesn't impact local weather. If the Sahara plan was viable, Lake Eyre would show it & Lake Eyre would have received the infrastructure to permanently fill it LONG ago! It is MUCH more viable to do that than do the Sahara, both in practical terms & also because of the economic situation of the country in which each are located, but Lake Eyre has not been done, due to the evidence clearly showing it does not impact the local climate! High mountains are needed to do that! & lets also be clear, planting trees in arid & semi-arid areas ALWAYS fails! If the climate rating is for semi-arid or above, ONLY grasses are possible to grow. C4 grasses use 30 times less water per molecule of carbon sequestered compared to any C3 plant. ALL trees are C3 plants. Semi-arid grasslands can NEVER be converted into forests!

Even if we find a way to do this, we would still need to overcome the issue of super salinity. The Mediterranean Sea is already having difficulties with increasing salinity due to less freshwater entering it, and a highly restricted flow through the Gibraltar Strait limiting exchange between the Mediterranean and the Atlantic. A second inland sea so far from the coast with only the Mediterranean as a feed source is going to have greater problems with salinity that will need to be managed somehow.

Using a lower point in the Northen Congo mountains chain containing the basin, the enormous and * 'till this day would be still BY FAR * greatest artifical lake in the world with the highest dam in the world * Rogun dam, Tajikistan, will reach 350 meters, when completed quite soon * the water would had found a natural spillway, from which the great majority of the Congo River inflow would run down in a great waterfall (in some variants it's used by a power plant, seems legit) towards the Lake Chad. Using again the morphology and orography of the area, the quite little natural lake's big sorrounding depression could have been filled with the Congo River's inflows, and BE TURNED IN A FREKING RESERVOIR BIGGER THEN LAKE VICTORIA IN EXTENSION AND VOLUME. And from there, finally, a series of canals could theorically feed all Northern Africa. Side effect, and good one indeed, in Congo, downstream the majestically giant dam, several channels would also would have provided bonifications, preventing malaria, and also to be used for agricoltural use. Same thing, according to Sörgel, would have happened to the desertic areas with his great Lake Chad canals, creating in a span of about 20 to 50 years, basically the greatest grain, fruit and veggies cultivation in the World. Sadly after some promises by Amercan Governament (we are talking about the Early Cold War post-WWII Period), with the fall of European Colonies, the governaments that saw Africa as the a potental great "Grain and Fruit Basket" for internal welth and growth (and ofc profits by the exports), abandoned Sörgel's dreams and the Afrika Project ended just like the well... fascinating but absourd Mediterranean Drying Project.

His project was going to be funded by the USSR so our president Bourgiba who was friendly to the west refused.. In the 80s, our weak government was pressured by France to abandon our nuclear research, and Dr Turki dodged multiple assassination attempts from the Mosad. The story is even longer than this, but I hope next time you can treat us like sovereign human beings, not livestock on a western owned farm.

The last time Lake Eyre filled was 1899???? Cause that's when Australia's worst cyclone in history occurred isn't it! I have no idea wtf you're on about, or how water in the south of Australia would cause cyclones over a thousand kms to the north! Not how weather systems work! Lake Eyre does frequently fill/part fill as a result of the extra water from cyclones though, but not the other way around

Sit back and wait. Melting ice caps and rising sea levels will do 99% of the work for us. We'll still need to make sure the Eyre Sea doesn't turn hypersaline. A pipeline from somewhere in the north to pump the most saline water back out to the ocean will probably be required.

Wow! A delicious dessert! I love to have dessert! Cakes, ice cream, etc.

Sounds like a great plan 👍

In light of this video, I wonder if you could also analyze the Trans Aqua project, the one that would connect a flow (like 3%) of the headwaters of the Congo River to Lake Chad. While not proposed as an inland fresh water sea and would only act as like an irrigation canal, is it more reasonable and doable?

I’m still waiting for that Biographics episode on Danny and how he ended up in the basement.

manmade saltwater inland sea is about as stupid square wheel. The limited inflow of new water through manmade channel would barely offset the evaporation which mean higher salinity and less fish. Salt would eventually seep into underground freshwater reservoirs below basically poisoning them forever. Much better idea is a freshwater sea in Australian desert created by diverting several rivers on the outskirts of the area.

Great project, I’d love to see it come to fruition! 😎

It would be possible to pump sea water into the Richat structure for evaporation and sea salt harvesting by digging a tunnel to the Atlantic and then use solar and wind powered pumps to bring the water up. That might work on a large commercial scale and may be attained without saltwater intrusion into ground water.

The Sahara desert is needed. This would change the weather globally causing unintended consequences

It would have to be an extremely wide and deep canal because of the amount of water that would need to pass along it and the amount of evaporation from both the new lake and the canal itself. Hard to see how it’s possible to establish a sound business case even if the engineering is available to do it. Even the Chinese North South Water Diversion project is uneconomic and causing lots of adverse side effects.

1-You lose species that live in the desert and who knows what impact that will have on other animals 2- The desert provides nutrients to the amazon and before anyone uses the "the amazon is older than the sahara" argument, what life needed millions of years ago to survive is different than what it needs today so the amazon would get screwed. Someone said hurricanes could get worse because the nutrients arent available but I dont know how that works 3- albedo affect. Deserts reflect sun. Water and trees absorb sun causing areas to be warmer (thats why snowball earth was so successful) 4- The evaporated water would affect weather currents and it could green the sahara which would cause even more changes 5- People have talked about the salt water affecting existing aquifers Wouldnt it be easier if people just lived on cruise ships if they were concerned about rising sea levels (not that its going to be a problem since if all the ice melted only 4% of land would be lost and only 1/2 of all land is inhabited and thats with a pop. density of at most 200 people/sq mi.

The African Wet Period started around 15,000 years ago, around Lake Chad there is an epicentre of R1b haplogroup, I was confused for a while until I learned that around 17,000 years ago people migrated all the way from Eurasia on the steppe back into Africa. So from 27,000 years ago our ancestors lived north of Mongolia and over that period of time a group migrated all the way back to Africa, crazy huh...

We are only at the beginning of reconstructing people's migration history. Europe's population, for example, got replaced at least 3 times almost entirely. (Neanderthals got replaced by first modern humans, who got replaced by farmers from the near east) Also there are several "minor" migrations that shaped europe's languages (The near eastern farmers got completely swallowed by a steppe people that we call "Yamnaya" who brought the european languages to europe, the only remaining language of the old inhabitants is, possibly, basque. Then there were several steppe people migrations, mostly of turcic origin, but also the magyars). We also have no idea when the suomi and the finns came to europe, we only know that they share an uralic ancestor with the magyars, who came much later.

The Sahara used to be full of lakes and seas, some 10k years ago, so making it wet again is feasible. The trick is to replicate the previous conditions: higher surface temperatures which cause massive updrafts and thermal cycles drawing moist air from the ocean to the interior. By suspending vast mirrors in orbit (using an orbital ring) and directing sunlight to small regions of the interior the thermocycles can be restarted.
