Apologies to the people of Burkina Faso for dropping the K out of your country's name.
(In my defense, I'm kind-of known for getting names wrong. But that was a doozy.)
U really r a name butcher. 😂
I loved the shout-out. I enjoy ur videos a lot. Keep up.
I am glad to be able to part of it smhw.
Btw, it's Yuri(Iuri) with "i".
Hehehe...
Shout-out from Brazil.🙅🏾♂️
And if u ever run out of ideas about videos, u should definitely make one about the complex racial diversity in Brazil which has the largest colony of japanese outside not Japan. The city where I am from Salvador in Bahia which has the largest population of black(africans) outside of the African continent.
I mean...if u ever...hehehe...

I spent a night out in the Sahara (on purpose) and the night sky is just extraordinary. You’ve never seen the Milky Way so clear. It was 35 years ago and even now i still get goosebumps
Gobi desert in mongolia (and we'll anywhere in that country) did the same for me, completely clear tail of the milky way, was incredible and in 30yrs I'll still be telling people that too
I had a similar experience in the Mojave Desert in America. Walked out into the desert in the middle of the night to see the sky and it was more clear than I could have ever imgined. The stars stretched to touch the horizon. Just beautiful. Still tell people about it til this day.
As in remote Norway
Guys, Kansas is really boring compared to those places but I drove through it on a clear night once and it was a blanket of the clearest stars from horizon to horizon. The lack of light pollution must have been the most important factor.

Simps won't be happy
The 12 000 year cycle has already started, the rain in the region is already increasing year over year, the part of climate change we aren't responsible for
Oh, yes yes yes yes YED
Thank God you mentioned the Amazon rain forest 😂 I already thought how you could not have that on mind 😋
But we could greed the Sahara partially, which would be good, since the Sahara was growing over the years anyway. An option can be use a system applied in the heights of Peru, where the humidity of the night and morning time can be converted into water. Whilst maybe not potable, it may still serve to water some plants. Also you can make sea water potable and make the Sahara close to the coast greener. There will still be more than enough sand for the Amazon forest (or what's left of it, if they continue tearing it down like they did over the past 10-20 years)
My thoughts exactly
In high school I studied a wind turbine that would also produce water through condensation, so it's kind of a win-win for isolated communities, I don't know what came out of it, but it could be interesting for that purpose
This was fascinating. Thanks. Also depressing. I've always wondered what it would take to regreen Australia, which is 80% desert and growing. However it isn't Sahara desert. It's rocky and water still flows in areas and it occasionally gets rain. I think it's salvageable, with an enormous, but not impossible planting and animal herd scheme. Many people still run cattle in these sparse deserts. My father was one of them. And a large portion of that desert has a massive inland underground "sea" or lake under it (The Great Artesian,) so bores may be sunk for water. Sadly, our current government are useless climate change deniers. All they see are the coal and minerals we have. Could you please do a segment on this possibility in Australia - regreening the deserts and eroded areas? Thank you. Love your show. 🐨💗🦘
That would be so amazing
Australia is about 30% desert NOT 80%
Well aren't cattle, and minerals basically 90% of Australia's wealth comes from? Yeah I can see why.
Don't feel bad. Australia, and New Zealand represent the best of the southern hemisphere my man. South Africa is becoming a third world country again.
Some of the benefits of these anti desertification projects are still questionable. Some are monoculture which some say is bad. Others just aren't working.
Yet I think we need a way to just battle the heat we create, because no one is going to fully give up their lives.
Even if the West became carbon neutral. Other countries will be burning coal, and growing their populations like crazy.
Figure out a way to radiate the heat back out into space. Engineer some super Redwood trees that grow as fast as bamboo. Have a 200 foot tree in ten years that people can live in, and capture carbon.
I just learned so much in less than twenty minutes and I laughed out loud several times.
You're a gem, sir. Don't ever stop.
"The Sahara is the largest desert in the world."
>Antarctica, the actual largest desert in the world, makes angry noises
chattering of teeth?
Also the open oceans are a desert, and they dwarf both Antarctica and the Sahara. They receive less rain fall, and have little nutrients, their great depth means that organic derbis sinks too low so the phytoplankton can not access it.
@Xnigma
Not sure what you mean. The open oceans can be regarded as a desert. Here is a helpful video on the subject.

Better Title would've been "Why Megachad Could Save The World."
Mega Chad is the Hero we need in 2021!
MEGACHAD™
:This Is How Megachad Could Save The-World.
Chad is a country.
But would it save the world? we'd all be bankrupt and the Amazon would be destroyed.
Losing 80% of the saplings in such a dry place isn't so bad, when you consider 1/3 of the trees replanted for GigaBerlin are expected to fail in a cool and wet place.
This confuses me. Trees use _huge_ amounts of water. Your typical birch tree uses 200 liters (50 gallons) per day on average.
Where's that water coming from for the Saharan tree projects?
Underground?
@@Mkoivuka ... and Air. Some trees are better fit for desert and savanah then others. And bushes. Also... According to some peple some of bushes also burn and talk to people. But thats another story.
@@Mkoivuka They are planting trees which are adapted to a dry climate.
actually some parts of the Sahara have huge underground water reserves
I look at it the same way as I look at colonizing Mars: Survival is not required, since their deaths are beneficial too: They add biomass, nutrients, and moisture to the soil when they die.
Great video JOE. It is my first one watched and definitely not last. Great and thoroughly explained with figures and corelation between processes. I am impressed!
"Greening would create millions of square kilometers of crop land"
except they couldn't because of all the solar panels....:p
Raise the solar panels two or three meters of the ground and make them semi transparent. Now you have both croplands and solar panels.
There's now solar panels that allow the correct light for plants to pass through and reflect the excess heat so it can be effective
*Nuclear Energy intensifies*
Grass grows better in partial shade so livestock, which if moved along correctly can turn this sand into rich soil

5:25 little nitpick: Terawatt is *not* energy, it's power. Energy is Terawatt hours. I remember it like this: My oven sucks 1 kilowatt from the socket at each moment and if I leave it on for one hour it used one kilowatt hour of energy. Cheers! :)
I dont think.u talk about TWh when producing energy.. bcoz the only interesting thing is how much it can produce at peak efficiency. If u have a 1 TW producing plant thats the peak u can produce at any time. If u have a oven that draws 60TWh and u only have it on for 1 min, then u will only have used 1TWh .. but u would have exceeded the production capacity by 60x. Thats why it seems to me useless to talk about watt/h on the production side, except when it comes to billing ur customers.
@@kungfreddie The point was just that you can't say 'TW of energy' because TW is not measuring energy, it's measuring power. Power and energy are two different physical concepts.

I’m sure others have pointed this out by now, but it’s not friction that causes the heating of the air during reentry. It’s compression.
Wow. I didn't know that. What's the explanation? (I suppose I'll have to look it up.) en.wikipedia.org/wiki/Atmospheric_entry
@@Nehmo Effectively, the air doesn't have enough time to be pushed out of the way and is compressed between the reentry object and the air in front of it in a process known as adiabatic compression. Another cool demonstration of this is a fire piston: en.wikipedia.org/wiki/Fire_piston

Congrats on 1 million subs Joe. :)
Another brilliant video on a relevant issue, very amusingly presented. Thank you! :-)
As an engineering student at Oregon State university I wrote a paper about terraforming the Sahara desert by pumping in water from the Atlantic Ocean and desalinating it using direct solar amplification using both reflective mirrors and lenses to boil off the water and use it to irrigate the desert. My paper got an A but ended there my designs were never modeled or built for testing however it would transform the desert into cropland in less than a decade.
It would evaporate before you could grow crops.
and destroy the amazon. and therefore terraform one desert to create another!
as a geohazard mitigation technician (my entire job is to alter terrain) I can tell you right now that a project that scale if even possible would easily take a lifetime to complete, even with modern technology.

Thanks for the video. I am in a small part involved in micro projects to green the Sahara. I work with Oxfam to help with planting trees on the edges of regular peoples farms to slow or stop erosion and help with rainfall.
Thanks for, as already mentioned below, crushing our hopes at the end of the video.
Then again, 40 years ago people in Europe were worried about the Sahel creeping down South further and further, and apparently that's still going on. So... I'd say there's still a lot to say for making sure that doesn't go on too much still. Also. Not only the Amazon rainforest, rainforests in Central Africa and South-East Asia have been getting a tough hit over the past 50-60 years, let's try to 'replant' some of that still.
all those projects about getting energy from the Sahara remind me of the sun shield they wanted to make to protect the earth from uv

I know this is going to sound dumb but... theoretically, could we fly an enormous reflective tarp over the ice caps and essentially lower the temperatures there to stop them from melting?
Forget the ice caps we need that in Arizona lol
Your gonna need a lot of reflective tarps to effectively do what you want
What we could do is scatter highly reflective particles on the ice to slow down melting
@@arjund.4817 Or satellites with reflective shit on them could orbit between the sun and the ice caps. The farther away, the smaller the reflectiive tarp on the satellite would need to be.
@@gordieallen6422 it wouldn’t work as it would just get battered by space debris, and assuming it did work it would blot out the sun for crucial ecosystems. It has massive potential to go wrong
Thank you for this and the references to Lake Chad. In elementary school, I would find something obscure yet interesting on the world globe. It was Lake 🇹🇩. I would quiz friends to find it on the globe. For some it was difficult to find...yet it was there. Lake Chad and I have a childhood.

Thank you for the history on the greatest lake. Glad it was a behemoth at one time.

Would be kinda smart to terraform deserts so we can perfect the process before we try it out on Mars.
Musk should put some of those billions he said he needs help finding uses to spearhead the green wall.
that's a bit of backwards thinking. Essentially this is saying let's experiment with Earth's global climate to discover what works and doesn't work. It would be better to use Mars as the test bed, and not the other way around. If something goes catastrophically wrong on Mars, it won't endanger anyone or anything.
I'm bout to say that. But ok
@@WestOfEarth Yes and no. Yes for the exact reasons you stated, no because it might not be possible to terraform Mars at all. And it's definitely more complex to create a working ecological system where currently is none, than to alter parts of one that already exists.
But nevertheless, it's not so great of an idea to terraform anything before we're entirely certain that we know what we're doing. It's not that climatology is vage--it isn't--, but that these systems are highly caotic, making it pretty hard to predict the outcome of any action we take.
Therefore, where we really should throw our money at are more powerful super computers and more sophisticated and advanced simulations. We simply need to know and understand more before doing anything we might not be able to reverse.
@@lonestarr1490 I agree theres lots of room for error, but also room for improvement, there has been beneficial terraforming on small scales, beavers do it all the time, say if you know the ice caps are melting why not use that to water desert regions on the planet. Maybe a magnifying glass in orbit over the northern ice caps where you could melt the ice caps yourself and capture that water and pipe it down North American all the way to Mexico, watering desert regions like California that need water along the way, basically like watering your lawn but on a continental scale. This way an event that would wreak havoc on coasts can be diverted to replenish things inland. Obviously there would be problems for certain organisms, one organisms perfect climate is another ones ruined, but no ones using that ice stacked miles high right now... Imagine Greenland being green again, without having to flood New York to do it!
Keep up the good work man. 😎
Hey @joescott
There is another consideration for not messing with the Sahara too much. That dust also significantly affects ocean temperature as it navigates west. Altering the heating/cooling would result in a lot more hurricanes hitting the east coast of North America, and with a lot more power behind them. So there's that...
Keep up the good work-I like your style of informing people-helping them to reason out an answer and not just believing everything they see on social media...
I’ve been following you for a while, but it really hit me today how much you dive deep with your research-bravo! It hit me when you brought up the low phosphorus levels in the Amazon. I was like, this is excellent!
No, the research for that video was kinda shallow.
The Amazon Rainforest is 56 million years of years old. During that time frame northern Africa greened and went back into being a desert more than 10 times! So we can expect that greening the desert this time will not kill the Amazon Rainforest.

Living in the SW & now the SE UK we get Sahara dust falls quite often. You notice it on cars, I suppose because they're smooth, clean, painted surfaces that you're close to daily.
It's most noticeable after a drizzly day. It's a very fine, light tan dust that you can see had fallen with the rain due to the splotchy nature of the patterns it leaves.
I'm sure it's falling out of the atmosphere all the time it's just that in those special conditions it's more noticeable.
I've been caught a few times making little piles of it with a fingertip lost in thought thinking of far off dunes in a hot, arid wind making millions of tonnes of this fine, dry powder under my... "LES, WHAT ARE YOU ON YOUR CAR AGAIN? I WANNA GO SHOPPING!"

"This was a stupid way of restoring land in the Sahel" This was such a great line!!!
8 billion with 45% success, or 50 quadrillion with 10 times more pollution that would be saved by the project? IDK, I think it was a pretty good way of restoring land, all told.
as a wise man once said
Ok so 80% of th trees died? That's still billions more trees than anyone else planted. Ad you know what we learn from our mistakes. We know how to do it better because we can see what worked and what didn't. I am so fucking tired of people who don't do squat and act like they're morally superior because of it.
@@DaDunge 80 percent in some areas, not overall
@@julia_petcos Actually it is overall.
Any land body under sea level can have seawater brought in by siphons to reserviors and use many small tubes so one priming pump can be used for each tube. Many smaller tubes make it manageable. Not one giant tube needing massive equiptment all custom made. Then dig another reservior lower and siphon fill that one. Do this at lower levels until you get to the lake flood area. Each reservior then has flow and can be used for fish farming or desalination. The last lake becomes a salt sea with no outlet. But massive evaporation does help green growth somewhere.
That transition bro. *Mint*

Food for thought: What if there always needs to be a desert somewhere in the world to balance everything out?
I dont think theres an actual need for the desert as it hasnt always existed, overtime more and more of the world is undergoing desertification.
Well the sand of Sahara help the Amazon. No sand from Sahara, may affect the Amazon
update: I did my comment before the video finish.
Yes. You know when he was talking about the Sahara turning green? Then the Amazon will turn to a desert as the axial tilt of the Earth changes and major wind patterns reverse. So the Amazon then supplies the nutrients to the Sahara.

very very nice intro but man, it got me excited to learn more about perseverance so I'm gonna watch the rest of the video later.
I’m surprise you left out “air wells” from the discussion. Air wells, aka fog catchers or atmospheric moisture condensers or even “moisture farming”, is a centuries old technique that is seeing some significant updates with modern technologies and GIS mapping. Basically they are big A$$ dehumidifiers, but there are unpowered ones that use simple pipes or nets. The ability to extract moisture out of the air, collect it, and use it for livestock or plants changes areas that are uninhabitable to harsh but livable. I’ve seen others discuss the idea of placing thousands of air wells along the northern edge of the Sahara and cooling it north to south using the natural moisture laden wind from the Mediterranean. no need from $14 quadrillion worth of wind farms.

@@davidanderson_surrey_bc Great minds.
I wasn't expecting this to start with Mars stuff, but I am not disappointed :]
Hey Joe, you said at 1:08 that the heat from entry into the atmosphere is caused by friction. The re-entering aircraft actually compresses the air below it, and this pressure wave which is essentially a hypersonic boom becomes hot enough that the radiative heating from this pressure wave creates nearly all of the re-entry heat. The friction heating is a power of velocity^3, but the radiative heating from the pressure wave is a power of velocity^8, so yeah much much stronger at orbital speeds.
I thought that still counted as being Friction just with a much greater magnitude. I have heard the term Friction used to describe Atmospheric Entry quite commonly.

Maybe easier to focus on preventing the desertification of the amazon, with the advantage that you are preventing massive change with unknown consequences, not causing it.
The main reason for deforestation is the people that complains of it in internet. Your demand on products from deforested areas is what makes people deforest them.
Pay for wood from sustainable sources, you may have to not waste forniture and use it for decades, you may have to pay for meat produced in countries that raise cattle in grass plains at a small higher price than a hamburger. What a nuisance, hint, Europe and yankeeland won't do that, cheap products above all.
@@Argentvs yes, I am careful in my personal choices (I'm sure I could do better).
I certainly don't but new hardwood furniture that isn't from sustainable sources. I buy meat farmed in my own country if not locally.
However, whether you think they're should be coordinated international action and regulation on the issue or whether any change should hinge on free market response to individual choices, both depend on large scale public awareness and concern for the problem. That is where "people complaining about it on the Internet" comes into play.
Privileged rich people in Europe and the USA chatting about it on the Internet may seem gross and hypocritical but it is potentially the step towards the social change necessary. Those people, as you point out, have the power to change things.
@@Argentvs well gads and goobers, lucky you. the Eww and Yankey land are in catastrophic economic and political collapse right now due to the failure of leftism, so we won't be able to incentivize global markets pretty soon.
Wonder if this will stop the deforestation or accelerate it. My guess is accelerate as all the markets we used to weigh on collapse in on themselves and the local governments over-correct.
Nah. Also, we don't want to become vegans. But we all believe that climate change will kill us.
@@asdf3568 Climate change won't kill most of us. The major difference between earth and Venus is that earth has water, photosynthetic life and less pressure. You can't get runaway CO2 heating when seaweed eats more CO2 than the worlds industrial capacity puts out. Stop ocean dumping and you don't need to worry about any other climate cause or stupid activist supported regulation.
Bonjour Joe, In the Canaries, which are a maritime extension of the Sahara, wind turbines are used to run desalination plants for the massive tourist industry there, water is also diverted to agriculture. Just taking back from the Sahara the areas that the Romans farmed would be a start.
Terraforming hear a lot about it and my question is always been trying to hear first thank you
I would think the increased precipitation (if that really happens) would help to accelerate the Great Green Wall effort, which could then become self=sustaining.
Bare in mind that covering the entire Sahara with both renewable energy type farms increased the rainfall by "1/4 of a mm per day". Unfortunately I would imagine that the low impact of the wall would not have a great enough effect to reach that self sustaining point, however ideal that would be
Very interesting as always. PS: The last "0" is missing in the cost of the wind turbines (before the .00).
And I thought I have free time!

Growing up in Algeria, I remember the state TV extolling the "virtues" of the Green Dam, a project to plant trees by the army, started in the 70s, to stop the desertification of the north where most people live. When I first saw it when I was in college, I right away thought how silly it was when such projects are handled by ignorant folks to use for propaganda purposes. Most trees are dead, and after almost 40 years, the project has never served its purpose. The desertification and drought continues, albeit it's due in part to the overall global warming, but if it was handled a little differently it could've done a lot of good.
Need trees and plants that act as water reservoirs such as Boabs, and cacti. They both act as stabilisers with deep roots and store water for long droughts.
Atmospheric entry "aerodynamic heating-caused mostly by compression of the air in front of the object", to a lesser extent is heating from friction or drag wiki

I love this channel, he cut through to the truth like... a plate of spaghetti
It's honestly fascinating how inter-connected every system on this planet is. Changing even the smallest thing can cause massive changes to the existing equillibrium, such as bringing in pythons to the everglades. But sometimes it can be change for good, like reintroducing wolves into Yellowstone, which literally changed the actual geography of the region.
Ok, not gonna lie but Joe "Crocker" jumping in on pronunciation was hilarious.
Do you think it is possible that the Amazon Rainforest area was not what it is now, but more of a grassland or Desert back when the Sahara was last green? Maybe they each switch between being the “Lungs of the Earth” during different time periods?
I agree. Geology sure points to that. Example: Antarctica wasn't always frozen. There are fossils that point to it being quite lush and tropical at one point. Biomes of the plants change. That's the only constant on this planet.
@JMEssex
No, the Amazon Rainforest is much older than that, existing since at least 55 millions years ago. But back then there might have been more phosphorus in the region, making the rainforest independent of this fertilization coming from the Saharian dessert.
@S Singh
Antarctica was green, lush, and lively when it was near the equator. So the reason for _that_ transformation is simply plate tectonics.
@@SSingh-nr8qz but when Antarctica had plants and animals on it, it was actually much further north.

I would say that this is pretty meaningful no? ;)
I live in El Salvador, the most deforested country in continental America, and worked for several environmental organizations for many years. I can tell you with confidence that most reforestation initiatives fail miserably precisely because we focus too solely on planting the trees, but allocate no resources to their care, and any expert will tell you that the first two years require a lot of attention including, paradoxically, cutting down trees to create space for bigger saplings to grow further.
The other huge mistake that many reforestation projects commit is planting the wrong species of trees or planting only one species. To impact positively the environment, we must recreate as close as possible the same ecosystem as the natural forests in the area. That means a diversity of native trees and plants that would attract the local fauna.
Finally, there’s a first step that is very often ignored in most reforestation initiatives: if the soil is heavily eroded, you need to start by rebuilding the fertile layer of soil and prevent erosion to continue, so the first thing that must be planted is any type of native grass and small bushes.
