How The Sahara will Turn Green
Vložit

- 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.

Jokes on you. My gf's name is Sahara.
@@truthseeker1934 is it? ask yourself, how exactly is it i know what Sahara requires?
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.
What about the windmill 20 year life span and solar batteries impact on the environment, how will these be curtailed?
..and it would also dump loads of salt in the soil and make the soil unsuitable for growing plants...
@@deanlonagan1475 Yes, obviously you could not use sea water for irrigation. That was never the point, either. It was just to elevate humidity and lower temperature through evaporation. Which, according to that suggestion, would eventually trigger a feedback loop of increased precipitation.
in the middle of Egypt, there is a massive lower region, with a dept of lower than 100meters. If filled up it would create a massive lake. Only thing what would be required is digging a 50km channel from the mediterranean sea to this hole and nature will do the rest. The natural forces will create a waterfall. Due to the extreme heat, the evaporation rate would be higher than the water intake would ever provide (depending on the size of the channel of course). This evaporation can be also caught to create fresh water. Only downside is the extreme salinity this massive lake will have over time.
@@dx315 not saying I’m disagreeing, but the reason people aren’t doing this the world over is because of the reliance on specific metals and the people who actually want to make money off of energy don’t see them as particularly viable long term. Don’t get me wrong we should just kill the coal industry and use nuclear power and natural gas with carbon capture, supplemented with renewables, but unless you’re ready to pull an asteroid of lithium and cobalt into orbit its going to be difficult to sell this to the general public
This is honestly such a great explanation. I have always had difficulty in remembering the Milankovitch cycles in my classes.

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

@@tamerx5 i was looking for that reply!
Glad to see that you are back! I missed these videos.
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. 🤷♂️
I for one.
Which is one of the reasons why the idea that man has any significant impact on the climate are so preposterous, future generations will laugh their heads off at the acolytes of the Religion of Manmade Climate Change.
Actually, humans have been around for at least 10 Milankovitch cycles. So there's that. We also survived ice ages which is no mean feat for people who evolved in temperate or tropical climats. And all of that with technologies little beyond rocks, sticks, plants and animal bones.
Brother believe me and go and check the Hadith in which Prophet Muhammad clearly told, that the Arabian lands were once green and will become green.
He said this 1400 years back and his words are written over thousand of books all over earth.
@@cathjj840I agree except for the stone age comment at the end. There is plenty of largely ignored evidence that humans have reached or even exceeded today's technological levels. All the "Ancient Aliens" crowd haven't considered that it's far more likely that our own ancient ancestors built all these things. They knew from old times that concrete, glass and steel buildings would disappear back into the Earth. Only huge stone structures would survive to mark their passage.
Increasing the amount of water and greenery in the Sahara (or more precisely in the nearest at least somewhat fertile areas) would be helped by the practice of permaculture and the creation of contour lines and swales, not allowing water to spill over the surface and evaporate uselessly, but to penetrate deep into the soil and form groundwater that can be used for prolonged thoughtful agriculture after the rainfall season.
permaculture only goes so far. A lot of you seem to think it can work in areas that have always been dry. It can not. What it can do is take an area that once had fertile lands on it and restore that to its former status, but it can not and will not make the central desert regions viable. That is a pipe dream. Most of the arid regions that can be restored were destroyed by early man not understanding how to properly maintain goat herds and other animals.
@@zarroth that's why the brackets mention what they mention. Of course you can't run permaculture in the middle of the dessert, but you can work on the nearest to it fertile land and trap rainwater in the soil for prolonged use.
@@vasilyd8578 yeah, probably not feasible is the core of the Sahara that gets
One example of the limitations of swales in the American Great Basin. You have big mountains, ridges and plateaus working together to ensure that the rain water doesn't run off to sea. But it still gets only 150-300mm of rain, only enough to support scrub vegetation. Indeed, a large proportion of the world's deserts are endorheic basins including much of the Sahara.
“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
centuries? at the rate diet ww3 is going we will be lucky to make it to the end of the year un-nuked.
because we probably will not
Nothing lasts forever and humanity is no different...
In just 200 years, humans have consumed millennia worth of resources and saturated our home with poisonous plastic. We’re screwed.
Civilizations are cyclical, as is our climate. The changes that come to both have little to do with mankind, and everything to do with our star. Solar cycles and spaceweather control Earth. Civilizations thrive in warmth and high CO2, and perish when the cold returns and the lower CO2 stunts plant life, disrupting the cycle and starving all animals including us.
You have been lied to, and are being lied to in this video. Green technologies and the whole global warming agenda is the opposite of truth and leads to much green in the pockets of the elite, and covers up reality... Earth's exit from our interglacial period and return to frozen.
The timeline had been skewed by a factor of 1000 for much reported data. The cycle is 12,690 years, w many smaller cycles interlaced, and is the geomagnetic excursion or reversal of Earth. 6000 years ago was Noah's flood. 12,000 years ago was the last full reversal.
Most ancient monuments fall in a line around the Earth, which does not match our current equator.
Once you understand this and the myriad other expected effects, all of the present turmoil and the actions of the WEF & governments, pandemic, democracy, war, food supply... It all makes perfect if not abhorrent sense.

Strange to show a nuclear plant when mentioning greenhouse gases as they don't emit them! Otherwise, a fascinating and very well produced presentation. Thanks!
That’s not a nuclear plant, that’s called a cooling tower. It’s commonly a part of a nuclear plant but also many traditional power plants have it.
@@khaledalanani2253 Yes, the cooling towers produce steam, not CO2 or methane or other "pollutants" (though you'd be right to respond with the counter-argument that water vapor could be considered a "greenhouse gas" ). Those towers were part of nuclear power plant in the video.
Not a big deal, I imagine someone thought it'd be just a great visual, seeing what looks like tons of smoke pouring out of a tower...
The real problem is setting up huge solar panel fields. They are inefficient and quite destructive of the ecosphere (and yes there is ecology in the Sahara) and the "darkness" of panels compared the the reflectivity of sand wouldn't be that great for the albedo of N Africa, I fear. IMO, they would be better off doing greening projects (which are shown to be pretty dang effective) which retain water and sequester carbon and can be scaled up.
I've been hoping Green tech would advance enough to be useful in scale, but that doesn't seem to be panning out.
not strange. purposeful. a political sleight of hand.
when i was in high school in the 1980's i thought about if they made a canal through the mid of Africa to cut down on sailing around the continent mainly for shipping. then i realized that if the canal were wide enough it would allow for sea life, probably mainly small fish, shellfish to exist in the canal and then could be harvested. and then using plant life to grow around the canal to continue to induce wildlife to live in the areas that are made green over time.
man makes huge construction projects all the time, even through out history. pyramids, Colossus of Rhodes, Statue of Liberty which has an interesting history, so why not a project that will not only be a commercial value but ecological one too

Another video stated if you terraform the Sahara Desert, (Video 1) then the Latin America countries such as Brazil; The Amazon Rainforest will cease to exist. It talked about trade winds picking up sands and redistributing it to South America, this means it will help the eco-system. If you remove all the sand on the Western Side of Africa surely the Latin America countries and millions of undiscovered species will die too
especially it will have an effect on sea creatures and other unknown species in the South Atlantic/Pacific Ocean. Suggesting, if you were to plant trees on the *right side of North Africa* then you could save the people suffering there.
To tackle this tax the people of the left side of North Africa, 'Eco-Tax' the money will be used to decrease drought and increase water supply, reshaping each of the following countries: Morocco, Mauritania and Mali. When terraforming the landscape try issuing out the idea of a 'Hydroponic Drip System' increasing productivity among plant matter and the soil, Allan Savory has a solution (Video 2).
Mega Chad just making a big scene and then leaving is such a Chad move on its own. It is unfortunate those who named it that didn't call it a Giga Chad, they're too uncultured for that
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.
Imagine if we are intelligent enough to harness the heat absorbed by the sand and convert it into energy. I mean rocks can absorb heat and contain it and sand is pretty much crystalized rocks at a microscopic level. Solar Panels a rudimentary invention of ours if you ask me. You are 100% right solar panels potentially create manmade deserts.
Not when they use oil in the panels.
i think a cheaper and easier idea would be to remove some rock material
from the tops of the Atlas mountains and see if clouds that are currently blocked by them will float pass them
an example in China is that the panels blocks the sun light, the soil under the panels are cooler, with irrigation system grasses can grow under the panels, then come the goats to eat the grasses, and the panel field is also a goat farm. In another place panels are built over a lake, it blocks the sun light and cools the water, and a huge fish farm is built in the lake. You can find the documentary film (in Chinese) in youtube.
@@baersworth2010 isn't it easier idea would be to remove some rock material
from the tops of the Atlas mountains and see if clouds that float pass ?
What I find fascinating is just how recently the green Sahara ended. Around the same time that ancient civilizations in Mesopotamia and Egypt began. There were already small cities in Turkey and the Levant, along with agriculture, when the Sahara was green...
The great civilizations appeared with agriculture and livestock breeding. In a humid climate, there is game in abundance. But when it became scarce, agriculture had to be invented to get food. The population exploded and with the cities, culture developed!
yeah so apparently human civilization is like 12000 years old. So like we’re almost halfway there to the next green sahara. I wonder how this fertile region and its disappearance causing a bit of a north-south rift would have influenced our species hunter-gatherer migration
There were humans 12.000 years ago but that was not civilization, that is around 6000 BC
Many of the Sahara pastoralists fled to the Nile Valley. Migrants from the Middle East introduced agriculture, so the Sahara pastoralists switched to farming, and that is how Egyptian civilization began.
No first farmer civilizations started 12 000 years ago
But small civilizations started even earlier
@@maverickvgc4220 I'm pretty sure modern human have existed for the last 200,000 years setting up settlements as they expanded out of Africa. The general consensus is Sumaria is the oldest civilisation which is from 6000 years ago. But its plausible civilisations existed way before that but have just been erased from history due to cataclysm. One theory is some were swallowed up by the ocean as sea levels rose due to the earth warming up. We hear similar stories of Noah's ark all over the world from civilisations that never even had contact. Not to mention isn't like 80% of the ocean undiscovered.
There probably have been human civilizations for much longer. We just haven't found any traces of them yet, or all their traces got destroyed over time.
But how was the Amazon area during the green period of Sahara?
I heard that in Pleistocene (1.8 Mya-10000 years ago)(after Pleistocene, goes the Holocene (10 000 years ago to the present day) (And during that period at latest point of time 20 Ka [kilo annum]- thousand years ago {20-5 Ka} Sahara experienced more rainfall at that time,thus becoming a fertile savannah with even some individual trees standing)*
Amazon rainforest was split on 2 isolated forest refugia with extensive dry grassland between them.
*Generally Pleistocene (or colloquially known as Ice Age, was more Arid than it's now, but some places, like Death Valley in US, or Sahara in Africa, received more rainfall!)
So, literally turning Sahara green, would have some consequences, so let Sahara be a desert, and Amazon a rainforest! Okay?:)
@@user-jk9qt8om5i how about we make the sahara artifically green
That is such a great question. Because the lushness of the Amazon basin depends a lot on the constant fertilization offered by the diatom-rich dust winds coming off the Sahara.
The Amazon is in the tropics, like Indonesia and more southern parts of Africa. Arizona, Texas, and most of Mexico are the same latitude as the Sahara on the other side of the planet. With that in mind I do not think there would be much difference.
Pretty much the same. The ice ages had more of an impact on the amazon than a wet sahara had. Overall, the amazon has remained pretty much unchanged for 50 million years.
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.
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)
Yes. We want to keep oppressing the people of the Saharan desert. You know, white privilege and all.
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 ...
@Matchbox Yesteryear Restorations We are being hustled. The atmosphere is 78% nitrogen and 23% oxygen. Co2 is .04%. Of that, man made co2 is just a fraction of that. Because of the higher co2 levels, the planet is greener today than it was 20 years ago. China, India, US and South America planting billions of treas to stop desertification, restore rainforests and use for lumber increased tree cover by 5%. Nobody talks about that.

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.
Until he started to talk about the wind and solar saving us from the dreaded climate change. What a joke.
you're right. another example that, (the) science is (never) settled. science by its very nature, evolves.
I don't really see that it is happening like you said. Generally this theory was accepted, but it had to integrate with other existing theories that had evidence as well. It should be noted, that there is a number of different cycles and influences on the climate. Just focusing on Milankovitch grossly underexplaining a lot of the climate changes of the last few hundred thousands and million Years.
When was this "sort of science" ever ridiculed by the mainstream scientific community exactly? Or are you trying to conflate this with climate change denial? This long term cycles has been know for a long time, but as explained in the video, they are processes that take at least tens of thousands of year, you can't possibly hope to explain changes from climate change, that happen in decades, through this cycles... totally different time scales.
Ask any researcher that especializes in the wet Sahara if human driven climate change is a thing or not.
I love the part where they actually know this about the future and are not just guessing, even though it would be a qualified guess.
Would it be possible to use massive solar and wind power installations to desalinate water from the Mediterranean sea and/or Atlantic ocean to irrigate the Sahara?
You won’t need to desalinate it. Even if you pump sea water into the desert, the sand will filter it, and you will have normal underground water reservoirs which can feed a green Sahara. But the cost and engineering to even pump sea water into such a vast area is immense.
And obviously, better land management would increase vegetation, which would have a positive feedback loop associated with it.
That's what actual scientists have already proposed, but science is complicated and political leaders like shiny new solar panels. Proper land management has already been used in Africa to regrow sections of savannah that were turning to desert.

@@Jamirio Mankind is too greedy 😮💨
based
Uhhhh, correct me if I’m wrong, but I thought the reason these areas were deserts wasn’t because of the amount of sunlight, but because of the convection between the equator and neighboring regions. It always seems a bit ironic to me, but it means the areas will always have a difference in water availability. Even if water availability increases overall, it wouldn’t be uniform.
the last technique to green the sahara would only make it swap places, as the dust blown into the amazonian rain forest will go down, wich leads to desertification, so you basically swap 2 regions.
seems like there would be an even amount of plant material blowing across, no?
@@Aconspiracyofravens1 well it depends since plant material is not sand, and that point there would be roots, so the said organic material and it is simply heavier than sand dust.
Why would it cause desertification?
@@randyralls9658 because the reason the amazon rainforest exists its becasue the minerals in the dust blown enriches the poor land of central latin america. If there are no minerals, the plants will die out, wich causes erosion, wich turns into desertification, floodings and landslides
@@lolyolopop_16 the amazon rainforest is extremely large and a fast majority of it is very healthy land or else we wouldnt be cutting it down for farmland.
But youre right
one question, if the sahara would become green again, what are the effects on the other parts of the world?
from what i heard if the sahara became green the amazon rainforest would dry up because one of the reasons the amazon rainforests rains so much is because of the dust from the sahara desert that travels to south america and makes the rain particles heavier, leading to it raining more. So basically if there was no sahara desert, the amazon rainforest wouldn’t rain as much and wouldn’t be able to sustain the wildlife leading to it becoming a desert in just a couple years
@@buzzlightyear1010 There are no deserts at the latitude of the Amazon nor can they exist due to the Hadley cell

Great video!
the Sahara's sand is like a fertilizer for the amazon so greening the Sahara is the same as deforesting much of the amazon.
so greening the amazon is the same as drying the Sahara further.
Explain?
@@ibrahimhassan711 that’s not how it works.
That's just bs. The amount of nutrients the Sahara provides to the amazon is negligible. One proof of this is that the amazon is way older than the Sahara desert, and not only that but before the amazon, there were other massive rainforests in the region, and the amazon itself being an ancient relique of a much warmer and wetter world that was covered with amazing rainforests stretching as far as the poles.
The andean volcanoes are the main source of nutrients for the amazon, sure the Sahara dust helps a bit but the amazon could totally survive without the dust.
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.
I have another theory. The climate will keep getting hotter because the Sun’s light intensity keeps on increasing with its age and there is a possibility that our planet will keep getting hotter and dryer until all the water and atmosphere evaporates. But maybe we still have time for some of these green cycles…
nah this is most likely bogus. Usually the right answer is the most obvious one, and all evidence point towards greenhouse gasses being the cause of climate change.
the period of time is too big for us to notice
and transitioning from fossil fuels to "green energy", won't make a hill of beans in stopping this process!! The revolutionary process of what ever life form survives will result in some other advanced life form other than homo sapiens, we'll be analogous to the dinosaurs of our period!!!-
Very informative and exciting for me, ty.
if the sahara was a rainforest it would still be extremely hot and humid right?
yep it would not become a temperate forest
@@Ultrapro011 depends on how big the glaciers are.
For example at the time when atlantis was supposed to exist it was possible to walk from south america to antarctis, just because of the amount of glaciers that existed on earth.
With the end of the last ice age the sea level rised by 120m, and just to be sure, the end of the ice age happened in one instant and not over an bigger time period. Because of this there even were everywhere in the world arctic days in summer just because the rain cooled down earth by so much
Might be easier and cheaper to pump water from Mediterranean Sea into the northern old lake bed, and use Atlantic water for the more western old lakes. Yes, it would be salt lakes, but the added humidity could create more rain in the area, and possibly quicker, but would also leave vast open areas for farming and settlement.
I've been thinking about this for months!! Something like the sea city in Kuwait but on a way larger scale (but tbf the one in Kuwait is more like a canal rather than a lake).
@@user-ih2uc2ji8i The test case in past to examine is the Salton Sea in California, what it was when existed by an accident, and what it is now today all dried up. It had life and fish around it, but today is just desert.
That's pretty much how the Arial Sea was destroyed by the USSR.
Damming the Congo would be more practical than pumping the Mediterranean
@@TheMaster4534 That might be a good idea too.
This is fantastic, thank you thank you!
When the Sahara first formed around 5 million years ago it was already a desert like it was today, but changed, and came back to the desert
I petition we rename lake megachad to lake gigachad
This is where I think the biblical eden and 6000 year old earth comes from. Humans blamed themselves for the deterioration of their homeland. As the area dried out, they left to avoid the constant fires that were "going all ways".
The bible says "a flaming sword that turned all ways"
Sometime ago, I saw a proposal for filling the Qattara Depression in western Egypt with water from the Mediterranean Sea via underground pipes. Personally, I’d rather see a canal dug because 1) ships and aquatic life would benefit from it and 2) all that surface water evaporating into the air could start a positive feedback loop not unlike the one mentioned in this video
I've heard that plan too, just with nukes instead of pipes
Aral Sea Uzbekistan: they pumped out all the water, the salt concentration killed all life and the sea disappeared as did the vegetation: an ecological disaster!
You have to plant trees, trees increase humidity and it’s a virtuous circle!
It's not just the Sahara... Australia used to be much greener and wetter, which changed when humans arrived and many existing species went extinct. The thinking is that this changed the ecosystem to what we see today.
How do these orbital effects impact Australia?
By the way, it's unlikely that more than one coast of Africa would be greened; the poleward edge of the Hadley cell is always going to desiccate a significant portion of any land area around 30 degrees latitude.
30 degrees North Latitude, or South Latitude? That's over sixty degrees of latitudinal difference. Thirty degrees North passes through Egypt. While 30 South passes through roughly the middle of South Africa. That's a ginormous difference in locations.
Please be more specific with your dire forecasts.
That will be another story. But of course in the past, Australia was an icy wasteland.
@@jacob4920 Fascinating, my reply isn't showing up anymore.
Draw a line along the 15th parallel, and another along the 45th, and another along the 75th. All deserts in the world are either between 15 and 45, or above 75. You can literally trace the southern edge of the Sahara desert, at that 15 degree latitude line.
"Ginormous"? Yes, but planetary atmospheres are that way. Look at the single atmospheric cell of slowly-rotating Venus, or the multitude of stormy bands on fast-rotating Jupiter. That famous "red spot" is several times the size of Earth itself.
To return to the deserts -- these occur because at the hottest part of the Earth, the tropics along the equator (no deserts there -- funny, that) the hot, dense, moist air rises. It cools and thins, dumping its load of moisture that nourishes thick forests. The desiccated air travels poleward, finally descending again at the 30th parallel... causing massive, continent-girdling deserts like the Sahara.
Does the same thing happen at the 60th parallel? Yes. And there, the dumped moisture again causes massive, continent-girdling "boreal" forests. And the desiccated air circulates either towards the 30th parallels, or the poles.
This isn't going to change with some minor alteration in the chemistry of the atmosphere. Only a truly catastrophic change, like a change in the rotation speed of the Earth, will make a difference.
@@jimluebke3869 You're mostly right, but for some missing elements in your argument. Let me just brush over them with a couple of strokes, and keep from getting long-winded:
1. Oceanic currents
2. Continental positioning
3. Topography
4. Geological chaos
Earth's rotational speed has more or less been the same for billions of years. Nonetheless, Earth's climatic regions have shifted greatly, multiple times, over the course of that length of history. There is even evidence that the Sahara Desert is "cyclical." Every several thousand years, the entire region swaps back and forth from desert, to forested, with almost nothing in between. Fossil evidence has shown scientists that this has even happened within the span of human history! So what's the driving force, other than latitude and longitude, or the rate that Earth rotates?
The answer must be that forces such as the North Atlantic Current (which dictates most of Western Africa and Europe's climates) either did not exist 6,000 years ago, or ran a much different course than it did today.
Going back much further, the ice-covered continent of Antarctica is "technically" a polar desert today, but tens of millions of years ago, when it was positioned much closer to Earth's equator, it was covered in forests and plains, not unlike Africa, or South America, today.
Then there is the factor of mountains affecting air currents. Note how it always rains heaviest on the ocean-facing side of major mountain ranges, but areas just on the opposite extreme of those ranges are very dry. The best example is in the "'Mediterranean climate' that California gets, from the Pacific Ocean, but the State of Nevada, which lies on the wrong side of the Sierra Nevada Range, gets parched of any rainfall at all. And those areas are pretty much on the same realm of latitude as one another.
So, you were right, but only partially right. If all things were equal, then everything between 30 and 60 degrees of latitude, on both sides of the equator, would be uninterrupted desert, and vice versa. Reality shows us this is not the case. Which is why there may come a time when the Sahara is no longer covered by desert anymore. We know for a fact that at one point, there was no desert at all in that region. So to say that it can't ever go back to that is just not grounded in fact.
@@jacob4920 It's very strange though; other fossil evidence (radioisotope analysis of Egyptian aquifers) indicates that they have not been recharged for hundreds of millions of years. Not "several thousand" -- tens to hundreds of millions.
This timescale actually starts getting geological - it suggests that northeastern Africa has been under the same atmospheric structure for that length of time, even as continental drift was occurring.
(Some models show Egypt to be submerged in the ocean at this point in geologic history; I'm not sure what to make of that.)
Lake Megachad should be called Lake Gigachad instead 😂
what a great video, you sir a pleasure to watch
I am shocked! They talked about possibly 'greening' the Sahara artificially by installing solar panels and wind generators plus carving the necessary rods but they said nothing about actually planting trees! Nothing about the Green Wall project ...
Trees can't just thrive everywhere you put them, the point of the panels is so that the plants growing below them aren't scorched by the sun all day and have a little shadow so they can't dry out.
@@frenchrevenge6406 There is an ecosystem in the desert. This waste in order to create electricity and make money would be an ecological disaster! We must plant trees and nothing else!
Very well researched high quality and entertaining video!!!
This is so exciting 🥲I would love to see a green northern africa.
you must not like the Amazon rain forest then. cant have the Amazon with the Sarah desert.
With our present Ecliptic (oval) orbit around the Sun
Earth is actually closer to the Sun in the winter, than in the Summer
The Northern Hemisphere, goes into Winter because the tilt off axis, has Northern hemisphere higher to the North
The UV waves have to go through the atmosphere at a greater angle, some even bouncing off an refracting back into space
Giving Northern Hemisphere our present day winter :(
Of coarse, when the Northern hemisphere leans away from the Sun
The Southern Hemisphere is raised to face the Sun, making for hotter Summers than what the Northern Hemisphere gets
The Equator lines up almost square to the Sun, giving it direct effect of our Sun energy at our planets closest point to the Sun
So when the Northern Hemisphere is in Winter,
The Southern Hemisphere gets full exposure to our Sun, making for quite the summer temperatures
It’s The Earths tilt off axis that creates our Seasons & allows winter in Northern hemisphere even though our planet is at the closest point to the Sun
The Sahara gets the direct energy of the Sun, so until either of our tilt reverses or Earth goes back to circular orbit
we get what we get, with things is what it is
Makes sense
none of it makes any difference
you know why?
if the tilt of the earth created lakes in the Sahara area the insinuation is that
before that there were no lakes in the area
meaning it was a desert before thee tilt
what caused it to be a desert before the tilt of the earth?
Thank you for the video! Truly, thank you.
1:52 --- it would be great to see how the Milankovitch Cycles affects the Haley's comet...
🤔🤔🤔and what about other comets, meteor showers, asteroids?
Just had to mention, when you talked about the rapid human induced climate transition caused by emissions.. you showed the steam from nuclear reactors. These don’t emit pollution, just water vapor. But overall great video!
Neutron radiation isn't pollution. It's toothpaste.
I saw in some youtube documentary that if you Green the Sahara, South America's Amazon will dry up. The sand in the Sahara fertilizes the soil in the Amazon, so the documentary says.
What fertilizes the Congo?
@@randyralls9658 It's animals, for the most part. The Congo is the most recent of the world's rainforests and depends a good deal on it's animals to spreads plants & fruits via seed dispersal. The Amazon & Southeast Asian/Oceania rainforests depend on this too, but they have other factors to help them - Saharan sands for the Amazon forest and volcanic ash for the Southeast Asian/Oceania forest.
Animal droppings in my soup. Poor it on the ground and plants will fruit.
That's just bs. The amount of nutrients the Sahara provides to the amazon is negligible. One proof of this is that the amazon is way older than the Sahara desert, and not only that but before the amazon, there were other massive rainforests in the region, and the amazon itself being an ancient relique of a much warmer and wetter world that was covered with amazing rainforests stretching as far as the poles.
The andean volcanoes are the main source of nutrients for the amazon, sure the Sahara dust helps a bit but the amazon could totally survive without the dust.
@@purplespeckledappleeater8738 Nice song...
This was once a lake named Lake Terachad.
Putting solar panels in the Sahara desert would be like an air conditioner in the Arctic .There’s nobody there to use it.
3:30 makes so much sense when you realize humans went north thru modern day Egypt
You would wonder why they would go thru a desert when they can go south but if the coast wasn’t a desert it makes total sense
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 ?
🦕💰
almost every city in the shara was already wiped out before, over the course of time multiple tsunami happened and one of these completly floded every part of the sahara.
Is not even that long ago, that happened cause the ice age ended
The Sahara desert, having a proper solar infrastructure in place, can literally power all of Africa and beyond if only those African countries know how to utilize the natural abundance of solar power capability that the Sahara desert provides🌍🌍🌍
Africans already know how, it's just that like any other project it needs loads of money and the govt that controls the money does not see it as a priority. Moreso even if they do, the project you suggest demands most countries being on the same page
It's amazing that you would think the problem is lack of know how.
Solar panels are not effective in deserts. You have sand destroying the panels and covering up the panels and heat that makes them less effective.
@@Nubbe999 Sand can be cleaned. There is this "unheard" thing called water that you can use to clean the solar panels?!
Heat does not make panels less effective. That's what those panels are built for...to stand out against heat and produce electricity.
@@vwati I did not mean "lack of knowledge" as in "lack of know how" per se because the Europeans have already given this idea to African countries long time ago.
What I was referring to is that Africans do not know how to prioritize their micro resources which they have in abundance in their own countries to ultimately invest in this mega project of solar power in the Sahara
Africa is filthy rich in resources including oil, gold, chrome, silver, iron, and so many other metallurgic materials that they do not know how to rally the people of those countries to extract massively and export.
@@vwati Yeah the governments of those countries control all the money because of corruption. They don't know that by not distributing wealth to the rest of the people will keep their countries behind and poor. It's a combination of lack of knowledge, greed, selfishness, carelessness and indifference.
Why is the effects of tilling seem like its being ignored in the videos on the Shara regions? Is it because we're still doing it?
Will that also turn the scandinavian countrys into tropic or whill we get a colder Temprature then what we have now ?
The Sahara is a desert due to it’s location in the sub-tropical high pressure belt.
Or maybe the sub-tropical high pressure belt is due to the Sahara.
@@randyralls9658 No, the pressure belts are a result of latitude.
lake gigachad* 4:00
I saw a video somewhere that if the Sahara got green, the amazon which somehow feeds off of the sand would disappear.
would like to see the effect from this in other continents
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.
No, the glaciers had retreated by about 13,000 years ago.
I think you have a point in general that he did't show the simultaneous developments in other parts of the world...
I like how everytime they date something back it's always an even amount of years 41000 years the earth wobble those kind of numbers I find that kind of suspect
Abu Huraira reported Allah's Messenger (may peace be upon him) as saying:
"The Last Hour will not come before wealth becomes abundant and overflowing, so much so that a man takes Zakat out of his property and cannot find anyone to accept it from him and till the land of Arabia reverts to meadows and rivers."
Wouldn't the sand obscure/damage the solar panels, though, before any real benefits could be reaped from placing them all out there?
Even if they are raised up pretty high above the surface the sand dunes can reach 180 meters in height and blown sand would still accumulate on platforms built higher than that.
To be honest the solar panels when they end the uses they arent recalled because it to hard
Are you also Atlas Pro?
Today, we know Arabia to be a hot, dry, and lifeless desert.
It’s hard to imagine it could have ever been anything else, really. This is the image that we all are familiar with.
However, completely going against this notion, the Prophet (ﷺ) stated that the Final Hour would not come until “the land of Arabia reverts to meadows and rivers.”. [1]
This is quite an interesting
inshallah the final hour will come soon, so the world can be free of sin and we can finally meet our creator!

@@australia5766 True.But this is only in our time.If you study Allahs sense of time then you will see that in Allahs sight there has not even passed a few seconds since the creation of the earth.
Maybe you could have mentioned, that despite some efforts to stop it, right now the Sahara is still spreading at an alarming rate thanks to deforestation (unsustainable [foreign] agriculture that destroys forest for more farmland until it falls to the desert, rinse and repeat plus construction and mining)
i say the sahara last week and now its already like the svana and it has alot of plants now
“Who needs a Giga chad When you got a MegaChad.”-A Giga Chad
Prophet Muhammad ﷺ stated that the Final Hour would not come until “the land of Arabia reverts to meadows and rivers.”
This is quite an interesting prophecy for multiple reasons.
First of all, pay attention to the fact that the word revert is used here. That means that Arabia once used to be green and full of meadows and rivers. Secondly, it tells us that it will somehow go from being a dry desert to a wet land once again.
"Prophet Muhammad (Peace and blessings be upon him) predicted that one of the signs of Judgment Day would be that the land of Arabia would RETURN to greenery and rivers, as it once was. Hadith (Muslim)
Sign of Qayamat right in front of our eyes
i definitely could be wrong, but im pretty sure the amazon rainforest relies on the sahara being a desert (warmed up winds that push over the ocean to collect moisture) so if that becomes green the amazon becomes a desert.
You could certainly reduce the size of the desert without getting rid of the desert.
@@genkimachina sure but if you get rid of the desert then the amazon becomes one, would reducing the sahara also reduce the amazon? i really don't know but its an interesting thought.
Lake Mega-Chad @3:55.
It seems very nice, but actually changing the desert into grassland is equally changing the Earth 's equilibrium.
This is just a thought, would like to know if it's all good
Also, would the grassland maintain itself or would it go back to """natural""" levels?
That's bound to have an effect on the global weather
Isnt the Caspian a lake? Since it doesnt connect to anything???
Higher atmospheric CO2 will help reverse desertification.
The fly in the pie of this theory is that Australia, at the antipode of the Sahara, should under Malkovitch be green today, in theory. It's not! It's drying out fast. In truth, there are a googleplex of cycles like there are grains of sand, and we are passing every day through a new region of space and matter being swept up gravitationally. Besides, the Sahara is on the Equator should have been your first tipoff that this was bogus.
You make a great point about Australia. but the Sahara is on the Equator? If so then so is Florida, new Orleans, and half of Texas! All of which are balmy swamps. and thick forests! Try using Google Maps sometime. took 3 seconds to discover you were wrong about this. Plus your ignoring the supporting evidence of fossils and artifacts.
@@AndyMorrisArt If you watched the presentation the 'wobble' puts areas ABOVE the Tropics of Cancer and Capricorn latitudes in extra solar insolation. The Sahara lies in the Equatorial band between the two latitude tropics, therefore does NOT receive the magic extra 7% mentioned in the video. Chile's Atacama desert should be as green as Australia and the Namib in Southern Africa as well. They're not. The entire video is anti-Science.
It is the Sahara that proves nutrients for the South American rain forests (as I understand it, from various nature videos). Does that mean a wet Sahara will not generate the winds and air flows that are needed for our rich and diverse rain forests?
although nice, its abit far fetched to say that you could just put solar panels and fix the participation cycle. that would demand far too many of them. how many does it require to do that?
