Well, those photos of Lake Mead are terrifying. Maybe severe water shortages this summer will wake people up that climate change isn't some liberal fetish.

  > climate change isn't some liberal fetish It's not and I'm pretty sure most people agree. But the activists are focusing their efforts in all the wrong places. We have Extinction Rebellion extremists gluing themselves to electric trains in London. Electric. In the mean while, the likes of China and India are by far the biggest culprits while Africa is projected to quadruple it's population while rapidly industrializing. The growing number of people is the main problem. The world is heading for the climate catastrophe and getting Americans to swap their trucks for Teslas is not going to change anything.

    Population growth in Africa has approximately nothing to do with the problems facing the American West. The problem in America is due to ridiculous property- and ag-developer-friendly water policies that resulted in “water credits” being tossed around like candy and a ridiculous belief that places like Palm Springs are built on “prehistoric aquifers” that will “last centuries.” Suburbanization is still in vogue in those parts. The problems have only begun.
  - adamcstephens 5y ago
    I agree with your final point, but China resource usage is partially attributable to American consumption. We can’t export all our manufacturing to other countries and then point at them for causing climate change.

You cannot blame them for having high birth rates, even Europe and America had high birth rates when they were poor. Birth rates in India and China are already below replacement, Africa's will also be later in the century. Do you think people in America are more entitled to have babies than in the rest of the world? The problem is not growing population, correlation is not causation. The root problem is lack of renewable tech that can sustain the modern quality of life for all humanity. I suggest watching this: https://www.youtube.com/watch?v=QsBT5EQt348 https://www.youtube.com/watch?v=QsBT5EQt348 It's high time people stopped the tiresome and senseless bitching about India/China/Africa having too many babies, and focused on renewable energy research instead.
    - tomjen3 5y ago
      Historically the west has pumped out more CO2, but we are not talking about historic levels, we are talking about current and future levels as those are what we can do something about. And here China and India is going to be the main issue in the growing CO2 production. This has nothing to do with justice and everything to do with physics. We haven't made great renewables for the same reason we haven't made flying cars: the tech is too far advanced for what we can do.

    >getting Americans to swap their trucks for Teslas is not going to change anything. That's like saying Americans buying iPhones in the late 2000s won't do anything for poor people in India and Africa, but they revolutionized communication and a lot of other things. Battery research isn't cheap.
  - rileymat2 5y ago
    It would seem the solution here is to use our wealth to demonstrate how to do this sustainably on a per capita basis. We have no high ground until we are lower per capita than these growing economies.
  - tzs 5y ago
    > In the mean while, the likes of China and India are by far the biggest culprits while Africa is projected to quadruple it's population while rapidly industrializing. India!? India emits less than half the CO2 that the US does, and almost an order of magnitude less per capita. China is twice the total as the US but about half per capita. Africa was way lower than the US both in total and per capita. And yes, per capita is the correct comparison, because the atmosphere does not care about arbitrary political boundaries. Let C be the total amount of greenhouse gas emissions per year that the world as a whole can produce to keep the climate within acceptable parameters. We do not have a one world government, so staying under C requires a per country approach, probably some sort of quota system. The question then is how to determine each country's share of C. One approach is simply allocate each country C/N where N is the number of countries. This approach fails because if country X splits up into multiple separate countries, with no change in any greenhouse gas related activities of anyone who was in X, the quota for every other country goes down. In fact, the new countries that were formerly part of X might all actually be able to shift toward more greenhouse gas production. Example. Let us say C = 10000, N = 200. Then each country has a quote of 50. The US finds it hard to limit itself to 50, having say 5 states that each on their own produce 30. Solution: turn each US state into a separate country, tied together in an EU like web of treaties so that life doesn't actually change much for the people living in those new 50 countries. Now N = 249, quota drops to 40.16 per country, and now those 5 countries that were once problematical at 30 each have quotes of 40.16 and are OK. The American Union as a whole would have a quote of 2008, and many of the new countries could now actually switch to heavier use of fossil fuels. It goes the other way too. If Russia for example was able to reform the Soviet Union and get back all its former components, everyone other country would see their quota go up around 7%. To fix this you have to abandon the idea of the quota being equal per country. The quota needs to be per person. Then all that changes when you redraw your maps and the US becomes the American Union or the Soviet Union reforms is who is in charge of enforcing the quota on a given group of people--the amount of emissions allowed by that given group does not change.

  I'm not sure the level of population in these areas would ever be sustainable, climate change or not.
- b9a2cab5 5y ago
  California's drought isn't caused by climate change, it's caused by industrial scale exports of highly water intensive crops. Photosynthesis effectively locks water into plants that then get transported across the globe, de facto exporting water from California (remember photosynthesis consumes water + CO2 to produce sugar and oxygen). Add on plants like almonds that inherently store moisture inside themselves and you have even greater water exports.
  - dehrmann 5y ago
    I'm not sure accurate the gallon of water per almond is or if it's still the case, but it's pretty obvious the most of the water isn't being exported, and a lot of what is exported would have drained into the ocean 150 years ago.
    - b9a2cab5 5y ago
      It could be 10% of the volume of an almond is water exported per almond and you'd still get the same effects. This is what happens when you grow crops on thousands of square miles of land and export all of them. It adds up.
      - dehrmann 5y ago
        > It adds up. Almonds take around 3 feet of water to grow commercially. The region they're gown in in California gets around 12 inches of annual rainfall. If the shortfall is covered with groundwater, you have a point, but a lot of it is also diverted snow melt (which, to complicate matters, can recharge groundwater). It really depends on where they're being grown, even within the central valley.

  They appear to be at least a little exaggerated as the bottom portion of the image is scaled larger in the “before” photo.

Yet Maricopa County, Arizona (Phoenix) had more growth from 2010 to 2019 than any other county in the U.S.[0] Clark County, Nevada (Las Vegas) wasn't far behind.

- AlotOfReading 5y ago
  Arizona today is using less water now than it did in the 50s, despite that massive increase in population. There's hope that by the end of the decade it will be entirely groundwater neutral. The population is not really the issue, especially given that domestic usage isn't anywhere close to the largest consumer.
  - whoisburbansky 5y ago
    That’s wild to hear, I’d be interested in numbers and/or how they managed to pull that off, what are some resources I can dig into?
    - AlotOfReading 5y ago
      Usage: https://www.azcentral.com/story/news/local/arizona-environment/2019/02/12/arizona-water-usage-state-uses-less-now-than-1957/2806899002/ https://www.azcentral.com/story/news/local/arizona-environme... It's not quite as amazing as it sounds because AZ households could still cut domestic usage to become comparable to neighboring states like NM. Regardless, we shouldn't focus exclusively or primarily on households because they simply don't use enough to matter compared to agricultural usage and they're way harder to manage policy-wise.
  - GavinMcG 5y ago
    That's good, since it sounds like there's less water available than there was in the 50s. Still, it strikes me that even if Arizona isn't itself a disproportionate consumer, being between the water source and even larger consumers (i.e. Southern California) it's set up to be in a tough position. Also, regardless of water availability, the other concerns of climate change are going to affect people living there. There are substantial wildfires every year, and not all that far from (expanding) communities in the Phoenix area, for example.

  - HarryHirsch 5y ago
    There's plenty of rain-safe farmland available in the Northeast. A good amount has reverted to forest because the terrain is easier farther out west, but the rains are failing there. We'll see it reactivated.
    - einarvollset 5y ago
      Okay great!
  - dlor 5y ago
    The price for the water is also several orders of magnitude different. Farms pay 100-1000x less. It's not drinkable so some difference is expected, but this is too much. Raising their price would ultimately increase food prices across the country - but that's the reality. Right now CA urban water users subsidize food prices across the nation.
    - einarvollset 5y ago
      If only 5% of CA water is urban use, then surely the subsidy is minimal. Also - driving the Central Valley I see no end of “Congress stole our water” signs, so clearly some change is happening. Why can’t agriculture in more rain prone areas compete?
diveanon 5y ago
For anyone interested in what this may look like, I highly recommend the book “The Water Knife”. It focuses on the water rights disputes of a future dystopian US where states fight proxy wars with each other to secure access to water. It’s set in Los Vegas and Arizona as they are coping with a refugee crisis of Floridians and Texans fleeing the impact of climate change. The author Paola Bacigalupi also wrote “The Windup Girl” set in a post pandemic Bangkok where calories have become the primary currency. Truly excellent hard sci fi set in the near future.
- sbierwagen 5y ago
  Windup Girl is not exactly diamond-hard science fiction, since the biopunk genre waves a wand and makes electronics largely go away. Energy storage is done by winding springs with working animals, genetic engineering features prominently, but for aesthetic reasons you never see the words "solar" or "electric motor". This was plausible-ish in 2009, (At the time the only EV on the road was the obscure and blisteringly expensive Tesla Roadster) but lithium batteries and PV solar are dozens of times cheaper now. Even with oil gone, it would be hard to imagine a Windup Girl future in 2050.
  - diveanon 5y ago
    My understanding of this was that they lost the ability to manufacture semi-conductors during the collapse and that the mining and refining process of rare earths was too energy intensive to be profitable in a resource starved economy.
    - sbierwagen 5y ago
      Sure, but like, coal exists. At our current consumption rate there is centuries of coal still in the ground: https://www.eia.gov/energyexplained/coal/how-much-coal-is-left.php https://www.eia.gov/energyexplained/coal/how-much-coal-is-le... It would be rather rude to burn it in a post sealevel-rise world, but it is still there. Even after peak oil there would be electricity and heavy industry. It wouldn't be hard to lose advanced semiconductor manufacturing, (A war in Taiwan would do it) but halting production of advanced chips just rewinds us to 1980, not 1600. PV production is ultra high volume and geographically dispersed. I don't see any way to take it all out without hundreds of EMP bombs or some kind of ultra-solar flare that fries all electronics worldwide. In which case you wouldn't have genetic engineering. Or cities. What's left of humanity would be in small villages, engaging in subsidence agriculture. You could set a novel in such a future, but it would be rather monotonous and unpleasant.

This is a very real issue and has concerned me for years. I'm an environmental studies major and water is something I think we don't take seriously enough. But when I was homeless in California for nearly six years, it was during drought years for the first five. Towards the end of that, I recall similar photos going around of empty lakes and boats and dick's sitting in the mud or on dry lakes bottoms. Then the drought broke and the last year I was on the street was much wetter. These were deadly storms with record rainfall causing much flooding. I borrowed money and spent three nights in the cheapest dive I could find, not knowing how I would eat for the rest of the month but certain that being out in the storm would cost more and have devastating consequences. The lakes and reservoirs filled back up. Years worth of deficits were remedied in relatively short order. I do wish we would take water issues much more seriously. But I also wish we would remember that variation in rainfall is normal and reservoirs exist because of that and it's normal for them to rise and fall. If you are interested, Salt Dreams is an excellent read about water issues in the American Southwest and Southern California especially. Fresno County has an excellent track record of raising its water table in some years and a lot of water rights law and canal building tech was developed in that county hundred or more years ago. This book about the history of Fresno water development was an excellent read (at least if you are a hydrology nerd, I guess) and I highly recommend it: https://www.worldcat.org/title/water-for-a-thirsty-land-the-consolidated-irrigation-district-and-its-canal-development-history/oclc/36954078&referer=brief_results https://www.worldcat.org/title/water-for-a-thirsty-land-the-...

For anyone interested in what this may look like, I highly recommend the book “The Water Knife”. It focuses on the water rights disputes of a future dystopian US where states fight proxy wars with each other to secure access to water. It’s set in Los Vegas and Arizona as they are coping with a refugee crisis of Floridians and Texans fleeing the impact of climate change. The author Paola Bacigalupi also wrote “The Windup Girl” set in a post pandemic Bangkok where calories have become the primary currency. Truly excellent hard sci fi set in the near future.

Windup Girl is not exactly diamond-hard science fiction, since the biopunk genre waves a wand and makes electronics largely go away. Energy storage is done by winding springs with working animals, genetic engineering features prominently, but for aesthetic reasons you never see the words "solar" or "electric motor". This was plausible-ish in 2009, (At the time the only EV on the road was the obscure and blisteringly expensive Tesla Roadster) but lithium batteries and PV solar are dozens of times cheaper now. Even with oil gone, it would be hard to imagine a Windup Girl future in 2050.

  My understanding of this was that they lost the ability to manufacture semi-conductors during the collapse and that the mining and refining process of rare earths was too energy intensive to be profitable in a resource starved economy.

    Sure, but like, coal exists. At our current consumption rate there is centuries of coal still in the ground: https://www.eia.gov/energyexplained/coal/how-much-coal-is-left.php https://www.eia.gov/energyexplained/coal/how-much-coal-is-le... It would be rather rude to burn it in a post sealevel-rise world, but it is still there. Even after peak oil there would be electricity and heavy industry. It wouldn't be hard to lose advanced semiconductor manufacturing, (A war in Taiwan would do it) but halting production of advanced chips just rewinds us to 1980, not 1600. PV production is ultra high volume and geographically dispersed. I don't see any way to take it all out without hundreds of EMP bombs or some kind of ultra-solar flare that fries all electronics worldwide. In which case you wouldn't have genetic engineering. Or cities. What's left of humanity would be in small villages, engaging in subsidence agriculture. You could set a novel in such a future, but it would be rather monotonous and unpleasant.

It’s going to get ugly when everyone starts coming east again.

This is a very real issue and has concerned me for years. I'm an environmental studies major and water is something I think we don't take seriously enough. But when I was homeless in California for nearly six years, it was during drought years for the first five. Towards the end of that, I recall similar photos going around of empty lakes and boats and dick's sitting in the mud or on dry lakes bottoms. Then the drought broke and the last year I was on the street was much wetter. These were deadly storms with record rainfall causing much flooding. I borrowed money and spent three nights in the cheapest dive I could find, not knowing how I would eat for the rest of the month but certain that being out in the storm would cost more and have devastating consequences. The lakes and reservoirs filled back up. Years worth of deficits were remedied in relatively short order. I do wish we would take water issues much more seriously. But I also wish we would remember that variation in rainfall is normal and reservoirs exist because of that and it's normal for them to rise and fall. If you are interested, Salt Dreams is an excellent read about water issues in the American Southwest and Southern California especially. Fresno County has an excellent track record of raising its water table in some years and a lot of water rights law and canal building tech was developed in that county hundred or more years ago. This book about the history of Fresno water development was an excellent read (at least if you are a hydrology nerd, I guess) and I highly recommend it: https://www.worldcat.org/title/water-for-a-thirsty-land-the-consolidated-irrigation-district-and-its-canal-development-history/oclc/36954078&referer=brief_results https://www.worldcat.org/title/water-for-a-thirsty-land-the-...

Stop government subsidy of cheap cotton. The US cotton industry in turn drives the global fast fashion industry. It's a complete ease to the bottom/ecological destruction.
