If green land creates oxygen and green land is created by water and humidity.
If we could create some seas in the middle of Sahara and other arid places as Middle east, Austrialia. wouldn't that create rain and humidity for nature?
Let's say we construct some nuclear power plants on the coast of Sahara, that can power some big pumps, and a pipe as gazprom constructed in Europe. till the middle of Sahara. and pump water from sea few years
If it would be big enough, wouldn't that create humidity and rain?
Or even better
there are sea level places in Sahara.
Just dig channels and water would be pumped by gravity from ocean
You can't beat Hadley cells. The water vapor will be pushed away. Even if you somehow manage to make it work, what would you do with all the salt that is being accumulated in those lakes? You will have to move it back to the ocean. Also, your best case scenario will create climate similar to India's, with unbearable humid heat.
An easier approach would be to use electrolysis on sea water and let the hydrogen flow through pipes to the middle of the desert. There you burn it to create electricity and pure water to sustain desert cities.
Those areas are close to the coast and would still need a mega project that is a million times more difficult than the digging of the Suez canal.
dont let the salt form
The Sahara used to be a forest. Didn't the Hadley cells operate back then?
It wasn't a forest, but a grassland and a savannah. The Hadley cells tilt northwards and southwards throughout the ages, IIRC due to earth's axis "wobbling" like a spinning top. The Sahara will be green again in about 10000 years.
Sahara is at the same lattitudes as India or the Carribean, obviously there must be more to it.
>You can't beat Hadley cells.
So how did India and parts of China cheat? After all, they are at the same latitudes as the northern desert belt.
Nature is quite like a video game. It's a zero sum game where speccing one point into trait "A" means you lose out on that point in trait "B".
It balanced the Sahara and India out.
>Sahara
It's a worthless plot of sand with a few Touareg and Arabs in it.
>India
Infested with Jeets.
Hadley cells don't matter for a climate that is bootstrapped up from the local geographical conditions, dipshit.
Except then you would be salting the entire stretch of earth you channeled through.
you're a genius. get started and report back.
The main reason why Sahara is desert is because there is little rain falling the area. The reason why rain does not fall in area is because it is very hot there and clouds are vaporized due to the heat. In turn, it is very hot in area because there is no evaporation in the area. As you can see there is a cycle. The artificial seas would have a cooling effect on environment, which would bring rain into the desert allowing plants to grow in there.
>create inland sea
>dries up within a year
Wat nou?
there are places at sea level, maybe with an artificial river from the ocean, you could have a constant sea. if it dries from temperature, it creates rain and humidity.
>what are you going to do with the salt?
by evaporation it cleans itself from salt
it evaporates, and rains all over the Desert, near or far.
>by evaporation it cleans itself from salt
Yes, it does. But the salt stays there, and it accumulates. And there's quite a lot of salt in seawater. You couldn't pump in 30 times the reservoir's volume before it completely fills with salt.
So you sell the excess salt in bulk to icy municipalities who need to treat their roads since there have been salt shortages recently to the point some are already resorting to sand instead of salt.
>Why don't we move large quantity of water in arid areas?
In a nut shell, the cost of energy/electricity along with all the other problems associated with large mega projects.
If you've got abundant, very, very cheap energy you can run desalination plants and pumps non-stop.
Like always, what are you going to do with the salt? At the least you would also have to pump it back as well, otherwise you'd soon end up with a massive pool of brine, and then it would fill with salt.
Best case scenario, you get something like the Salton Sea or the Dead Sea.
https://en.wikipedia.org/wiki/Salton_Sea
isn't ocean or sea water less salty than those high salty seas?
Also what is wrong with it?
i see lots of green fields near Salton
Do those green fields get their water from the Salton Sea or is it piped in from a fresh water river. We both know the answer but you can pretend that you don't if it helps your mental state.
If you drain a river in a landlocked basin, the only way out for water is evaporation. Fresh water is still salty, just less than ocean water, so the lake would quickly see increased salinity.
Also, you can have lush rainforests near the ocean shore, doesn't mean they get their water from it.
i was just watching Allan Savory speaking on climate change and how hard is plant forests in hot places. he said that Arabia used billions to clean water from salt and plant trees 1% of its country and the desert is still fighting, and had a curiosity. i saw the question on other site buy answers where low energy, so i asked again here. you overprojecting mental illness all over
nevermind
i found other answers

i won't ask questions here again
you are to salty
Did you read it? It is full of drivel like
>The idea is “risky, unproven, even unlikely to work," according to Y Combinator.
Since when were they an authority on anything??
I want to live in Dunefrica where the gazelle and lions run pellmell away from the still semi-arid sandy regions as the replanting is underway, because they sense the vibrations of the worms, the worms we bio-engineered to till the sandy soil deeply and distribute the moisture so a better water table can form closer to the surface and the morning sun won't just take all the water we're piping into the area.
The pipelines are all occupied or destroyed by raiders or stopped at the source by pirates. The colonies are in danger but for now the UN won't allow any combat with the aggressors so I have to trick far into the sands past the stomping grounds of the moisture-maker worms with my genius Nubian-Ethiopian half-breed gf. We carry as much fresh water as we possibly can, not water for the worms or the soil, just fresh drinking water for the isolated desert villages newly established in rocky areas of these lands, where the worms can't reach them.
She's determined we must save and recycle as much water as we can, but her tired body gives out as the herds of frightened gazelle rush past below us, and the quakes from the great worm coming to devour us grow apparent. In despair and exhaustion she slumps to her knees and pees her stillsuit, forgetting in her terror to recatheterize herself and turn on the filter pump.
Anyways yeah maybe basic irrigation would be good for Africa.
wouldn't it make more sense to dig deeper wells and use solar to pump it out?

Wait, you forgot about the rain. sure, let's say you are right and an unlivable salt lake is formed. It still evaporates massive ammounts of water, which would fall as rain and create streams and rivers and ponds and lakes. With the heat of the sahara, the evaporation would be great and so the rain would be regular and plentyful.
Second law of thermodynamics. Not all the water that evaporates from the lakes will return. Some will be lost and make its way over other lands whose tributaries do not feed those lakes, or to the ocean itself. Ergo, there will always be ocean water flowing in without the prospect of removing salt. I suppose you could physically remove it somehow, but that would require energy, and thus cost. So, you re back in the same problem.
>Ergo, there will always be ocean water flowing in without the prospect of removing salt.
No, no, i agree with that. There would definitely be some form of a salt lake.
What i'm saying is, that that lake would evaporate and create fres whater via rain in other regions. So despite the original man made lake being unsuitable for life, it would create arible land via the rain it causes.
How long is that going to last? Do you have a reason to believe that the water stays in the Sahara once you pump it in? How do you get more water in once the lakes fill up with salt? The plan to divert a river and refill lake chad is probably the most realistic one.
there already exist basins, no need to dig, just dig a channel from ocean, to fill them with water
let's say you cover 3% of Sahara with salty water, is not much of a poisoning, anyway it is covered in sand.
Even better, we could make a pipe from Baikal, that has 25%of fresh wather of planet. and pump it in Sahara.
I imagine that Baikal could regenerate
Or just pump sea water in one end of the sea, then pump briny water out the other side. That was easy.
Why can't you just build large long aquaducts layered with semipermeable membranes that progressively filter the salt and dump it in collection stations along the the long path to the desert it traverses instead of putting all the salt in one place at the end?
saw something about there having to be a desert. either in africa either instead of the amazon. Amazon gets nutrients from the desert via air currents, something of that nature. might be wrong tho
That would create far more arable land, and the extra vegetation would reduce CO2. Globohomosexual doesn't like that because they want to starve the population, so is not going to happen ever.
You can't just introduce large bodies of water into arid areas and expect the land to become green, it doesn't work like that. Those areas are arid because they are dominated by high pressure caused by descending, dry air in a process known as the Hadley Cell.
Just look at Arabia, it is surrounded by water yet still isn't lush.
mountains seem to help
i saw a Dakar pov in Arabia, is not really just desert
Also isn't the desert preventing clouds to enter inside the arid land? and if you force water inside, you force clouds too?
>Why don't we move large quantity of water in arid areas?
because Black person population would explode and destroy the world.
Woahoho there that sounds pretty colonial to me.
You act like anywhere else can even get positive birth rates and this isn't a demographic certainty already
>You act like anywhere else can even get positive birth rates and this isn't a demographic certainty already
wtf?
Non sarcastic response: Its not done because it costs too much money and gives nothing in return.
Its just a waste of money. A greener sahara is not worth the cost.
You'd just make everyone poorer by doing that.
Why not make the poles green and lush? Why not make the ocean into a rainforest? How come we dont turn the himalayas into a tropical rainforest too. We have to make everything green, we cant just co-exist with non-vegetable matter in the same planet.
Every mineral must be coated in living vegetables.
The last 200 years of terra-forming and human intervention in ecosystems has made me superstiously believe that we really shouldn't play around with nature and conform it to our own selfish will, even with the good intention.
Where do they dredge up you drooling chucklefricks? They must go into abortion clinics and hook you out, then feed you straight corn syrup and put you to work on the internet.
Its not enough to just pump water you would have to create soil for plants to grow in.
Hydroponics says no.
how did the Sahara use to be wet? does this mean air currents was different and another place was dry?
