[@dragonseye00]

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)

[@dryb3301]

My thoughts exactly

[@shigekax]

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

[@StephBer1]

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. 🐨💗🦘

[@alexia3552]

That would be so amazing

[@michaelsinclair8018]

Australia is about 30% desert NOT 80%

[@dianapennepacker6854]

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 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.

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.

[@ProfessorPhysics]

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...

@@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.

[@mikejones-vd3fg]

@@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...

Food for thought: What if there always needs to be a desert somewhere in the world to balance everything out?

[@oatesi]

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.

[@carrerasrivera]

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.

[@rauminen4167]

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.

[@FireShine-ss4sb]

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.

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

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...

[@RCS117]

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.

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.

[@subashchandra9557]

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.

[@bookmew1081]

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.
