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.
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.

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. th-cam.com/video/MT28gm9CNuI/w-d-xo.html
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)
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
"It was vastly bigger, and they called it MEGACHAD, which sound like the final boss that you fight after you defeat all the others CHADs" "The Amazon is being saved.. by MEGACHAD" MEGACHAD is our lord and savior. Oh my..
When we looked at Caribbean rock samples in college in thin section, amongst the glaucontie, fish scales, anhydrites, and shell hash, there were usually one or two well rounded quartz grains mixed in there too. Those were grains of sand that found their way into the Caribbean from the Sahara.
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.
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. 🐨💗🦘
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.
@@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
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.
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.
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 would be good at suggesting stuff like that but never to execute them lol
Do you mean the Montgomery Burns, evil plan to block the sun? Or the Bill Gates double-plus-good plan to block the sun? news.yahoo.com/bill-gates-backing-plan-to-stop-climate-change-by-blocking-out-the-sun-183601437.html
Or the UN project which planted lots and lots of trees south of the Sahara - 80 percent of which have died again by now, due to lack of care. Anything they announce, they don't start, anything they start, they mess up. Yay for politicians...
joe, there is a fantastic episode of radiolab that talks about the dust storms off the sahara, and if you're not already a listener, you will absolutely love the show!
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.
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.
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.
@@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!
Even though Simon has seemingly covered everything on all his channels. I'd watch Joe's take. Simon is famous enough to go traveling to the places. No idea why they don't go behind the scenes.

Please don't. Those videos are so low quality, sparsely researched patchworks with a ton of errors, nothing like Joe's material. I watch them sometimes, but almost always end up being upset by the obvious lack of effort. Simon reads the script, has no idea at all what he's talking about. The Blaze is fun tho. Yet I don't see any reason for them to collaborate.
@@albertjackinson Not collecting them, but it's a recurring pattern for me to think, dude, you got that wrong. Clearly a quantity over quality approach there. Well, at least they're not intentionally misleading, like many others on YT, I guess that could be taken as a compliment.
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.
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.
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!
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.
People from thousands of years ago definitely didn't know what they were doing. Their projects just didn't have the reach that ours do now, but in many ways ancient peoples were more destructive because a global consciousness about the environment hadn't developed (and didn't until the 1960s). New Zealand and Madagascar were both colonized within the last 1000 years and both experienced massive extinctions immediately afterward. The Americas did as well, but there's controversy over whether or not humans were responsible (for NZ and Mad. there is no debate). Easter Island is also a prime example of just how badly ancient thinking can effect the environment.
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?
@@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.

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.

Hey Joe! I have this question that I hope you can answer or elaborate on and maybe even make a video about so here it goes..... If a solar system has two or more suns is it possible that a habitable zone is completely different than ours? Perhaps larger or getting heated up by both sides therefore making it much larger then ours? I really hope that you’ll see this and be able to answer it! Thanks in advance and congrats on 1m subscribers much deserved!!! Please like this question so that Joe might see this and answer it, thanks in advance
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
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.
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!"
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.
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.
It is harder to terraform the only planet where we can live on, than an empty planet. We should only try terraforming Earth when we have plenty of experience in it and have other home planets.
You're right but our motivations need to be clear and the consequences understood. After all, when it comes to Mars we're like "Maybe we could make things better by nuking the shit out of the planet?" and.... yeah. That's not a good fit for Earth. Don't do that, fellow humans. :P
@@0ne0fmany That's a great idea and all, the thing is that we've been anthropo-forming the earth for more than a century. (Anthropo- vs terra-, as we're not making the earth (terra-) more earth like, we're making the earth more human-like (anthro-).)
I like that you arrive at the conclusion that it is a stupid idea after 60 seconds, but then keep talking about it for another 18 minutes. That's dedication.
No it doesn't the Amazon has been rainforest since the Sahara was ocean floor. Yes it may run out of P some time in the next 7.000 years but I think we can figure out a solution before then and there are way bigger threats to the Amazon.
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...
Have you looked into any of the research that shows that changing farming practices, especially stopping annual plowing could be an extremely effective way of sequestering carbon.
In the mid 70s Algeria did plant the green dam which stretched from its eastern to its western borders cross its Sahara and was few miles deep. That's what the green belt project is trying to replicate now
That's why we'll first want to bring that metals-rich asteroid mentioned in the news recently back into high earth orbit. Then we can get all the metals we want from there.
@@agustinkrupka Not long term. Yes there may be raw material shortages in the short term but eventually someone figured out how to do it with cheaper materials and the race to the bottom resumes.
@@DaDunge I think the real problem is that they need maintenance and to be replaced eventually that produces waste, that the cities that need the energy are very far away that have a very high transmission cost and not to mention that installing and maintaining this technology need a lot of SKILLED labor that is not exactly the people that are unemployed currently
That Dyson swarm doesn’t sound so crazy now. Also, if we green the desert, where are the sandworms gonna live? Shai-hulud gives this idea two segment ridges down.
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
Great video, as always Joe. I can't help but wonder if the key is, instead of trying to create one big climate change, try to create lots of little micro climates. A slow accumulation of oases across the desert, which is gosh darn big.
You forgot to mention that if even we were able to do this, the panels and wind turbine are only good for about 20 years. Meaning that in a few years we will have to do it all over again
Well power plants need constant upkeep as well (rather than being replaced in power plants they just replace parts when they go bad or fail inspections, constantly, all the time), could just have ways of breaking them down and recycling them to make new ones. Give people long term jobs just replacing them as they start to go bad in cycles.
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.
Question: Don't the deserts serve their own role in the balance of our global eco system? I know we want to make the entire planet green but by that logic , we can go into frozen tundras and start making them green as well. That doesn't mean it's a good idea for the entire global climate system.
The Sahara sands that blow over to South America is said to give the Amazon much needed minerals so terraforming the Sahara might kill the Amazon. The more we try to help the more we mess things up, should be the motto for humanity
You are correct that deserts serve a role. However, the situation in the Sahara is what is called desertification. The slow change of forest to savannah to desert. The Sahara is the fastest growing desert in the blanket expanding by several football fields every day. Desertification is a destructive feedback loop that is actively degrading Earth’s biosphere.
They certainly can, but there have been a vast number of configurations to Earth's global ecosystem over millions upon millions of years. The most recent African Humid Period was less than 20,000 years ago and ended only 6,000 years ago. The Earth can survive as an ecosystem in which there are literally no deserts on the planet, cold or hot because water was so evenly spread across the Earth.
Or, change the way that we build cities and do farms. Why we farm only in 2D? Why not skyscraper farm highly industrialized and automatized and let be dense forests in the actual farm places? Why permit houses when we can live in hive like cityes (again, skybuildings/subterranean). There are a TONS of better ways to solve problems. But why solve when we can hold Power doing the cheapest way!?

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)

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.

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’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
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.

Hey, love your work!
joe, there is a fantastic episode of radiolab that talks about the dust storms off the sahara, and if you're not already a listener, you will absolutely love the show!
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.
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!

People from thousands of years ago definitely didn't know what they were doing. Their projects just didn't have the reach that ours do now, but in many ways ancient peoples were more destructive because a global consciousness about the environment hadn't developed (and didn't until the 1960s). New Zealand and Madagascar were both colonized within the last 1000 years and both experienced massive extinctions immediately afterward. The Americas did as well, but there's controversy over whether or not humans were responsible (for NZ and Mad. there is no debate). Easter Island is also a prime example of just how badly ancient thinking can effect the environment.

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.

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

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.
"Terrawatts"... Heh, I see what you did there.
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.

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.

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.
@@lonestarr1490 thanks for the breakdown and theory. 😁
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.

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.

Question: Don't the deserts serve their own role in the balance of our global eco system? I know we want to make the entire planet green but by that logic , we can go into frozen tundras and start making them green as well. That doesn't mean it's a good idea for the entire global climate system.
The Sahara sands that blow over to South America is said to give the Amazon much needed minerals so terraforming the Sahara might kill the Amazon. The more we try to help the more we mess things up, should be the motto for humanity
Yes. Do this, and the Amazon will die.
You are correct that deserts serve a role. However, the situation in the Sahara is what is called desertification. The slow change of forest to savannah to desert. The Sahara is the fastest growing desert in the blanket expanding by several football fields every day. Desertification is a destructive feedback loop that is actively degrading Earth’s biosphere.
They certainly can, but there have been a vast number of configurations to Earth's global ecosystem over millions upon millions of years. The most recent African Humid Period was less than 20,000 years ago and ended only 6,000 years ago. The Earth can survive as an ecosystem in which there are literally no deserts on the planet, cold or hot because water was so evenly spread across the Earth.
Or, change the way that we build cities and do farms.
Why we farm only in 2D?
Why not skyscraper farm highly industrialized and automatized and let be dense forests in the actual farm places? Why permit houses when we can live in hive like cityes (again, skybuildings/subterranean).
There are a TONS of better ways to solve problems. But why solve when we can hold Power doing the cheapest way!?
