In the future, the Sahara Desert will turn green. Due to the Earth’s slightly elliptical shape and the gravitational pull of other planets in our solar system, the Earth’s orbit, tilt and wobble gradually fluctuate over time in a process called the Milankovitch cycles. By affecting how much and where sunlight hits Earth, these cycles have a significant impact on the long-term climate of Earth. One of these effects impacts the climate of northern Africa. Every 26,000 years, more sunlight hits northern Africa, causing a positive feedback loop that spreads vegetation across the region. While we are currently in a dry period, in about 13,000 years, it is expected that the Sahara will enter a humid period and turn into a green, lush region. To speed up this process though, there are ways to artificially green the desert while also harvesting green, renewable energy.

Too late to experience a wet Sahara, but too early to experience a wet Sahara
Some sources I’ve seen mention that India would dry out during a wet Sahara. Also, India’s current climate could be a preview of what North Africa will be like during a wet Sahara.
Anyone else find it funny when he mentioned Lake Megechad😂
I like the methods in the scientific approach of the author: Very well done!!!
I am going to spread a link of this video to some of my networks and I hope to help public spread of the evaluated time scales to decision makers.
Incredible video, haven’t been this invested in one for forever. Love to see more topics like this that sound bizarre but are very possible. Great work
I find great pleasure in the fact that at one point in history there existed a lake megachad.
“If human society is still alive and thriving by then…” love that we so casually question whether or not civilization will survive the following centuries
Good production. Thanks. It’s amazing how, just a few short decades ago, this sort of science was ridiculed by the mainstream scientific community. A perfect example of how open knowledge benefits the masses, who aren’t as ignorant, as the ‘experts’ would like to think.
Have a look at Permaculture in India, the Paanii foundation
On our current path we wont make it past 2040
The Sahara is currently shrinking, due to increased CO2. The added CO2 in our atmosphere gives plants more to breathe, making the harsh environment a little more endurable. The time when CO2 was at it’s highest concentration is also the time of highest biodiversity.
The Phaethon story may be a cultural memory of a solar event. There are at least thirty known stars that undergo recurrent Nova events. One star is known to Nova on an annual schedule, there is another that has a period of 38 years, and a third that goes off every two hundred years. There is evidence here on Earth that can be construed that Sol may be one of these stars. The timeline is suspected to be every 12,000 years. For more information check out Suspicious Observers here on YouTube.
Until he started to talk about the wind and solar saving us from the dreaded climate change. What a joke.
The Saharan jetstream migration cycle is roughly 20.5ky, the wet cycle ended 5ky ago removing villages into emerging cities, it wasn’t expected to switch back for 15ky and seems to be.
The astronomical forcing creating the previous cycles has been blown away by loopy jetstreams carrying cold from poles over land to low latitudes to balance equatorial overheating.
It doesn’t change back until oceans cool back down, maybe party ice ?

About 30 years ago, I read about a theory that if large volumes of seawater was pumped into reservoirs in desert areas and allowed to drain out again through canals, it would cool the desert enough to start a cycle of increased rainfall in it interior. But this requires a massive engineering effort to create all the necessary canals and reservoirs and pumping stations.
This is honestly such a great explanation. I have always had difficulty in remembering the Milankovitch cycles in my classes.
I am doing my small part to re-green the Sahara which is intent on expanding here into the Algarve.
I surmise that if we , as a world community, re-greened the gulf of Yemen- Oman, Somalia, Yemen, Saudi Arabia, but especially the highlands of Ethiopia, we would re-invite the Monsoon to shower the Sahara with quantities of water. Let`s get to work!
This video completely fails to explain and compare the fact that during the same time that the Sahara was green, worldwide sea levels were much much lower and most of North America was covered under large glaciers. So in order for the sahara to go green again, it would have to cause an opposing reaction elsewhere.
The Sahara is North Africa.
Watching videos of technological and ideological marvels, it really seemed like we humans have come a long way and accomplished a lot. But in the context of the history of the planet itself, we’re literally nothing. Our entire recorded history is like a fraction of one single such natural cycle of Earth. That’s why these kinds of video really put things into a much more humble perspective. Even if humans are no longer around by then, who’s to say another species might not have developed to colonized the planet like we did. 🤷♂️
you’re right. another example that, (the) science is (never) settled. science by its very nature, evolves.
When Lake Megachad went gone everything around went dry.
@Reflect Card yes you can’t be wet without Chad
wet sahara and gigachad
Sahara desert is good for the oceanic ecosystem with the sand blowing long distances bringing needed nutrients to the phytoplankton. It also gives nutrients to the plants in the Amazonas. Would be better to end deforestation there + other places and maybe just terraform the eastern and southern part of Sahara Desert
Could be, India (and Pakistan) is extremely hot in the summer. Most places in the subtropical latitudes that are as hot as India are more arid (ie Sahara, Arabia, Iran, Afghanistan/Central Asia, Tibet/Gobi desert, SW US/Mexico, Australia, Kalahari). The one thing that’s unique about India is the Himalayas, which cause rain to occur when moist air masses run up against it.
You do see a similar phenomenon along mountains elsewhere, but on a smaller scale, like the south shores of the Black Sea and Caspian, the Caucasus Mountains, Atlas Mountains, Sierra Nevada, Eastern Australia, Mexican Cordillera and certain parts of the Andes. These would probably be a lot more desert like if not for the mountains, although the effect of the mountains is still on a smaller scale than in the Himalayas. There’s some pretty crazy stuff going on in the Himalayas where the steep elevation profile and intense rainfall are causing extreme erosion over a very long time frame and exposing some very unusual rocks that formed really deep underground.
India gets its rain from the Monsoon, which comes down from the Himalayas, and is actually the reason why Africa isn’t covered in tropical rainforest today. Back before India slammed into Asia, and created the Himalayas, rainwater from Asia swept west into Africa and drenched the continent, meaning most of not all of the continent was covered in tropical rainforests like you see in the Congo today. The formation of the Himalayas however blocked that rainfall, the sheer altitude of the mountains meant that the clouds soaked up so much moisture so fast, that by the time they got over them, they couldn’t hold on to it anymore, and the water got dumped onto India instead, while barely any made it to Africa.
As a result of this, the continental rainforests disappeared, and much of Africa became a patchwork of grassland and sparse trees. Which, ironically enough, was what caused our ancestors to come down out of the trees, and walk upright for the first time.
i’m a megachad
Wouldn’t the Sahara turning into a lush grassland mean that the Americas will no longer get the the Saharan dust transported to the continent and will cause the vegetation there to dwindle?
the Earth is an interconnected web of relations and the Sahara getting greener will certainly mean that other parts of the world will become the “new” Sahara.
Lol yea
@NatureOfStock Look at a world map: India is far to the north of the equator. You’re thinking of Indonesia!
One problem with the solar panels idea people tend to try to shoehorn into the Sahara…
Solar panels are basically big heat radiators… that absorb energy. Unless you are capturing the waste heat somehow to reverse the drying effect that this heat would induce; you will just create more of the same problem all over again. It’s the catch 22 of solar panels. They both absorb energy; and release it. It’s part of why it is darn hard to make really efficient panels.
That’s not to say that panels can’t be part of the solution. We just need to be more creative than ideas like “let’s just put a bunch of solar panels over here to absorb this free energy.”
It will certainly create electricity for you; but the benefits will not outweigh the disadvantages if you don’t do it right the first time.
Thankfully, there are companies who have realized this and are creating liquid cooling loops for panels which help transfer that wasted heat into heat pump systems for later use. THIS will create that energy syphon effect you want from panels. Along with a couple other tricks I have up my sleeve still, yet to be properly used by any industry yet.
I for one.
theres dudes growing forests in the sahara right now
Civilization doesn’t necessarily require organic living beings by then either.
Next will be MegaKaren….
I scrolled down into the comment section expectation the first comment would be about Megachad. It seems my calculations were correct.
Soon I’ll be too dead to experience a wet Sahara 😮
sahara dust also blocks tropical development until august so that is a good thing
Deforestation should be illegal worldwide. We can use bamboo for everything we use wood for and bamboo is regrown in 1 year. Much more sustainable and also proven to be stronger than iron.
The articles I’ve read mentioned that what you’re saying would be a problem for the Amazon basin, and possibly for the northern part of south America, but not the Americas as a whole.
Even for the Amazon basin it wouldn’t be a disaster. There would be less fertilizing dust, but, as long as there’s adequate rainfall, it would remain a tropical forest (assuming no humans would be cutting or burning it down)
Do you know what a nova is?
impressive a lake that the oldest boat was found close to the modern sized lake chad
one question, if the sahara would become green again, what are the effects on the other parts of the world?
@Ryan98063 interesting !
@iTerminator lmao 200 years is optimistic. Society will collapse by 2050. Humanity will recover afterwards though, although I imagine a collapse would lead to billions of deaths, not to mention how it takes a bit of time for the climate to fix itself
No, the glaciers had retreated by about 13,000 years ago.
Prophet Mohammed said that arab land will return green and rivers before the doomsday ..
FFS I was really interested in the beginning of your post and really really REALLY hoped you’d cite a source to shorten my looking into this idea. Then you had to mention Suspicious Observers, a channel that has been thoroughly debunked, then debunked until it was ground to dust, then the little dust pieces were debunked, dissolved in water, drunk by the debunking monster, pee’d out in a yellow wave of debunkery, then debunked some more. There have been so many channels debunking some aspect of Suspicious observers. Professor Dave probably has the best overall examination of what is wrong with this borderline mystical woo woo factory. So disappointed. For the first 3 sentences I thought I might actually learn something new. What a let down.
Out of the box research is how science progresses, keep up the good work!
@FrostyPops unfortunately bamboo is susceptible to insects and rot
@Corn Pop not if its treated. Wood has the same problem if its not treated. You should look at some of the houses and bridges made out of bamboo these days. Wood is of the past.
@DarthBricksEmpire I was referring to apocalypse, destroyed, no survivors…
Cant get a wet sahara? Try a wet sarah insted
CO2 increases continents’ temperature, which extends deserts.
Buy an EV, that’ll fix it.
@FrostyPops Bamboo is the future?
Sahara was green during the cretaceous.
@comingviking what about desalination plants?
Not when they use oil in the panels.
@Andy Clark actually, more CO2 plants needs more water.
and how unfair is it for North Africa to face water shortage and starvation alone ? especially considering the generosity of the west when it comes to immigration … I don’t see why they should take the hit to protect countries who do not genuinely care about their wellbeing …
It’s possible in Nigeria, from the Atlantic ocean to lake Chad, then the Sahara gets it’s salt water
not going to happen if you use sea water… where do you think all that salt is going to go? Nothing is going to grow on salted land
@P T I said “drain out again through canals”.
We shouldn’t try to change climate like that. What side effects would these actions have in other places around the world? Also the salt sater is no good for the land.
LOL! Imagine the eruption when that one burst? YUK!
No one can predict the climate. There are far too many variables, with the Sun having by far the most prominent influence . But one thing is certain, and that is that we need double the volume of Carbon in the Atmosphere for plant life to thrive optimumally, which has absolutely no effect on Global warming cycles. If man had not come along, plant life may have become extinct at 2 parts per million of CO2 in the atmosphere. This is totally opposed to what the corporate media tell us, isn’t it? I heard a corporate scientist attacking Nitrogen the other day. With 80% of the atmosphere being Nitrogen, I am in hysterics wondering how he is going to tackle that one?
