How Geography Turned the Sahara Green

The Earth's climate is in a constant state of change based on its position relative to the sun. This relationship means that as the planet's relationship to the sun changes, unexpected series of events can produce remarkably different landmarks. Such a thing happened not too long ago in Africa, where, for a brief time, the Sahara desert reverted back to a lush grassland. Today we're exploring all the various factors that led to the Sahara turning green.

First, that the land that the Arabs have known for tens of thousands of years to be a waterless desert was full of greenery and running surface water. Second, that that same unforgiving empty land will again be full of greenery and rivers. NONE at that time and geographical area could have known that. Especially that Muhammad, peace be upon him, was illiterate. NONE could have imagined such a thing let alone to predict it. Muhammad, peace be upon him, was called a magician, crazy and a liar, yet he was never apologetic and went with full force in what he believed in. He relentlessly preached the oneness of God and ridiculed the pagans despite all prosecution. He made all kind of unimaginable claims at his time, despite being laughed at, but it's all coming to be true. With global warming and a new ice age, the desert will again become full of life. But at that time the Quran yet again miraculously describes space as seamless fabric that at the end of times will rip open. Then nothing will help a human being but his good deeds.

You forgot another development that will green the deserts -- the breakdown of the jet streams. The jet streams separate the latitudes of climate. The cold polar region separated from the temperate. The temperate zone separated from the desert latitudes. That is why the Sonoran, Mojave, Sahara, and Arabian deserts are all in those latitudes. When the jet streams break down, storms will take more unpredictable paths. That is what has caused the odd weather in North America, for instance. I expect storms to then randomly move over the Sahara as well.

The depressions in the Sahara can be made into salt water lakes by digging canals to the Med, Red Sea and Atlantic. The large water surface will evaporate causing rain. The rain will green up parts of the desert. In time the canals can be blocked as rain keeps the levels constant which will eventually turn into fresh water lakes, or lakes far less salty. It will also counter raising seal levels in the world.

[@kevinbyrne4538]

From "Online Etymology Dictionary": Savannah: "treeless plain," 1550s, from Spanish sabana, earlier zavana "treeless plain," from Taino (Arawakan) zabana. The Tainos were a Native American people.

[@arjunsatheesh7609]

@@kevinbyrne4538 Could be that the Arabs got the word from the Spaniards. Not very surprising since the Iberian peninsula has a history of Islamic conquest. Interesting etymology. Anyway, the Arab word is also Savanna.

[@kevinbyrne4538]

@@arjunsatheesh7609 -- In Europe, the Taino word "zavana" became the Latin word "zauana" (in old writing, u and v were often written and printed using the same letter) in 1516 and then that became the Spanish word "çavana" in 1519. So the word would have to have been introduced into Spain after the last Arabs were driven out of the Iberian peninsula (1492). The Arabic word for savanna is "alsaafana", which is very close. Unfortunately it appears that no etymological dictionary of Arabic exists.

Can you do a video on when different civilizations found out that different exotic animals exist For example when did greeks learn od hippos or rhinos or lions and what was their reaction and so on

[@TheRealMagicBananaz]

Lions were native to Greece

[@islandsunset]

Alexander the Great's army were the first Greeks to encounter Elephants in India. And most probably the Tigers. Lions were once native to North Africa, Arabia, Anatolia and Persia along with South Asia. Now they are extinct in all of those places with a small populatuon natively living in India. So that's why Greeks probably knew about Lions.

[@CSABHOF]

Would be a cool topic

[@_egghead]

This would be very hard to research with accuracy

[@CaptainQuo]

Hippos lived in islands in the Mediterranean at one point, they were much smaller though and this may have been before what we call Greek or Hellenic civilisation existed. Can't remember. But it was due to a phenomenon we call insular dwarfism, where species are smaller on islands

The diagram at 3:55 is VERY misleading. Our perihelion is 91.5 million miles from the Sun, while aphelion is 94.5 million miles. That's a 3% difference. I know you clarified that this isn't the cause of winter, but when people see that diagram, they often assume that these distances cause seasons.

[@Makeitwithmanny]

Wesley Morgan he clarified, there for it isn’t misleading. He clearly stated therefore, making one KNOW that it’s not the cause of winter. There for it, and he isn’t misleading anyone.

[@wesleyrm76]

@@Makeitwithmanny I teach high schoolers, and one thing I've learned is that people only remember a small portion of what you tell them. Can you repeat all of the facts in this video? Our brains only save a small portion of what they observe, and it is more likely to be things that confirm our beliefs. So if someone already thinks that the Earth gets drastically closer to the Sun in summer, they will see the graphic (which comes FIRST), confirm their misconception, and likely not pay full attention to the explanation that follows. Derek Muller from Veritasium did his PhD research on learning with videos. I'd recommend checking out his explanations of learning and misconceptions.

[@Webderful]

The issue wasn't that amazon burning which is normal but to a much smaller scale, it was mainly concerning because large swathes of land were being cleared for agriculture like cattle and soybean. These could lead to a permanent loss of rainforest habitats unlike natural fires.

[@WHO_is_on_first]

Hypothetically, though, humans could speed up the process of making Africa green through reforestation efforts, especially since the Sahara is expected to get more rain in the years to come. So we could start and quicken that positive feedback loop and use it to bring the Sahara savanna back to suck carbon out of the atmosphere

@@VineFynn ummmmm, we don't? Ecosystems are constantly evolving and conservation projects dont just plant trees, they have scientists that pick out what trees and grass and vines would best suit each other and then when the land is grown enough the introduce animals that would benefit the forest.
