Same here. If California had ad adequate aqueduct system all the spring melt water from the mountains could be used for crops and a general fresh water source but instead they go through flooding and run it into the ocean. You can look at the fact the paved the river in LA to divert it somewhere more convenient to them while not to helpful. All the money spent trying to control where rivers flow could be used much better if people just accepted the flood zone and live on the outside edge. Again, aqueducts could help turn more area green by using this overflow. We are advanced enough to know what to do when the planet decides to change things up but people are too stubborn or stupid to understand that we are not facing the end of the world. The sky is not falling. We are just getting new gifts. New challenges. Adaptation is a way of life and always will be.

@@NaomanSaeed Hello Naoman Saeed.....OK, I do a modest bonfire with large chunks of dry hardwood on top, and when the fire matures to full conflagration, I put out the fire as quickly as possible with a garden hose, then pull the pile apart with a (non-flammable) gravel rake, and hit it with more water to make sure the fire is out. Then I scoop up the loose charcoal to be crushed in my concrete mixer (with some rocks to smash it to powder. Originally I crushed it by hand on a large flat anvil like rock but the concrete mixer does it better and quicker). The big chunks must be scraped clean of charcoal with a paint scraper and set aside for later fires. Here in the US there is commercially produced bio-char using huge kilns that can cut off oxygen to the fire, thus putting out the fire at the right time. I just like doing it myself. And this is not new tech.....ancient Native Brazilians made bio-char on a vast scale to make the poor Amazonian soil more productive. They dug trenches next to rivers and built fires down in the trench, then opened channels to the river and flooded the fire at the right time. Pretty clever.

I can't remember where, but I recently read that shade from solar panels in a field doubled the biomass and nutritional value of grass(?). Nothing special was done when installing the solar panels, the effect was accidental. If I remember correctly, they found the shade kept the soil cooler which helped it retain water longer. Shade plus more available water balanced out to plants growing more slowly but for an extended season. I think it might have been on a university campus in a semi-arid area of Oregon. Using land for grazing and solar isn't a new idea, but maybe it would make sense to do it on desert margins. I wonder if it were done on a large enough scale if a sort of reverse urban heat island effect might de-desertify unused land on the desert side of the farms. Maybe with TLC there, trees could grow more shade to further widen the cool island.

Was looking for videos about this topic. My luck that the great Isaac Arthur picked it up for elaboration.

I've often read that soil fertility in deserts are among the highest in the world. It's the lack of water that's the biggest reason there's little vegetation. That's why oases are so rich in plant life, and they are real, I've seen them myself during our many camping trips in harsh deserts. My old man who got his masters in meteorology said a desert is simply a region that has a net loss of water annually.

23:40 Isaac Arthur covers Flat Earth I died

There was a plan proposed to build wind farms of the coast of northern Africa where the prevailing winds were onshore to pump a spray of sea water high into the atmosphere. The salt would settle out to fall back into the ocean and the water mist would be blown inland to form clouds.

I like how you're not a one trick pony and are actually interesting when it comes to not just rejuvenation biotechnology, but it seems like everything else as well. One of my favorite KZreadrs. :)

Another great video. I think canals in Northern Africa will not only stop desertification but also help fight climate change. Unlike money games and politics like the BS Paris Accords that did nothing but give countries money, this could bring water and a possible mode of transport to land locked countries.

One aspect of desert reclamation which is usually hugely underestimated is the effect on global weather patterns caused by the changed albedo and thermal properties of the surface on a very large scale. I don't think we can predict that yet.

We realize you were probably very busy this month. Thanks for keeping the excellent content coming out. SFIA!

If you want to know all the nasty side effects of greening a desert, look at farming in the California central valley. Unless you have a huge source of distilled water salt will slowly build up.

humanity is not in any way "a few short decades away from extinction". Global warming will just flood some coastal cities and farms. Climate change will cause some regions to become poor farmland and whole regions of people will starve. But as a species we will survive and some places will become even better suited to farming thanks to all of this. Like here in Finland people are pretty happy about the effects of global warming. I think the bigger problem is all the animals and plants that *are going extinct* due to climate change and habitat loss (not to mention ocean acidification or the plastics and poisonous chemicals that we are dumping everywhere)

Always a pleasure watching your videos keep up the good work

I live out in the mojave, and I have done some documentation of the plants that live here. Some of the plants in dry lake beds taste very saline, and I think the dust can be distributed through the valleys to make very fertile soil. An alternate approach is to dig a hole that is sealed with plastic, then build a mini aquifer with a well. This would allow land itself to store the water from flash floods, and there is no shortage of carbon material out in the deserts. I also think the Creosote shrubs that make up most of Nevada's biomass, with an incredibly efficient use of water, could be a good candidate for terraformation on desert planets.

1. What do you think about peak phosphorus? 2. What about locally focusing the sun's energy on salt water in order to hear it to the point where the pressure created from this heat would create the pressure differential at the same time, meaning it can help desalinate water while using it's kinetic energy like a dam does? 3. Some places don't allow you to collect rainfall, even when it's directly on your property. But I really like this topic, it makes sense to use the sun's energy where it's strongest and driest to reclaim lost land, feed more people, and act as a massive carbon sink all the while. There's a simple plant organism, like algae, which we call 'pondweed', but it has recently been called 'lentein' (even though it has nothing to do with lentil's. Interesting thing is it happens to have an amazing amino acid profile but also has mineral and vitamin content. Perhaps we could grow that, on mass, and feed millions of people/ livestock. My concern is the possible environmental cost of creating all of these structures, and what to do with all the excess salt we have afterwards.

Also,Geothermal power plants can produce electricity and fresh water 24/7 if located on seashores. Cheap to build and the technology was available yesterday.

I heard one time a teory that amazon river was articially made transposing all rivers to one desert in area making the rainflorest

"Take advantage of the large pressure differential between the top and the bottom of the ocean to act as the pomp to.." This pressure differential is equilibrated by gravity, with the bottom having to compensate the weight of the column of water above which makes high pressure. So if you want to exploit such a pressure differential, you have to spend at least the same amount as the energy you will extract (+entropy) to counteract this gravitational force (with increasing the potential energy of your fluid, which means pomping it until the gravitational potential energy of the high-pressure zone is equal to the one in the low-pressure zone) before you can exploit this pressure differential... Basically, you'll make the water of the bottom go to the surface with an isopressure process. You can't extract energy with the pressure differential because you'll spend more energy first to elevate the water. This is dictated by laws of conservation of the potential energy of the fluid.

@Isaac Arthur I was hoping to hear you talking about "biochar" and maybe " mychorizal fungi" throughout the presentation. Those topics bear a busload of interesting factors favourable to the efforts.

Great episode.

BTW, most deserts, including most hot deserts, aren't sandy. Even the Sahara is mostly not sandy. Greening them in most cases is not much more complicated than adding water.

That eliminates the need for storage, and requires only 20% of the solar panels (because they don't sit fallow 18+ hours a day).

Does it hurt being so smart? Man, I love your videos! Thanks Isaac!

Hell yeah! A shout out to Real Engineering for also being cool as hell! ++++ SFIA ++++ RE

Hell F-ing yeah...It's Arthursday! Thanks Issac! Love your channel!

You mention artic. There are volcanic areas like Deception island. Just using geothermal energy, lighting and the heat is available for greenhouses. However, the Antarctic Treaty System prevents such use. A good way to look how that would search bannana production in Iceland (now effectively shut down).

Your quality is just goddamn no words can describe it you Sir I inspire to be as dedicated and disciplined as you.

Slight point from the intro: the deserts are receding now in places where humans are not actively cutting. The reason is simple: CO2 causes plants to lose less water to the air. They eat CO2 and have a respiration problem. They need to make holes in themselves for CO2 to get in, but when they do water also gets out. When the CO2 is more abundant, they make less holes. So more CO2 makes plants more efficient at living in dry environments. And satellite photos show green spreading. So the way to solve desertification is to burn more fossil fuels. More CO2 == less deserts.

Viewers should read up on The Great Man-Made River in the north African country of Libya. This is a network of pipes that supplies water to the Sahara in south Libya from the Nubian Sandstone Aquifer System fossil aquifer. It is the world's largest irrigation project. It supplies 6,500,000 m3 of fresh water per day. The total cost of the project is projected at more than US$25 billion. Estimates indicate that the aquifer could be depleted of water in 60 years. On 28 August 1984 the Libyan president Muammar Gaddafi laid the foundation stone for the start of Phase 1 of the construction of the Great Man-Made River Project.

8:00 Glacial flow sped up is very interesting!

yes! i love this topic
