Study Finds Western Megadrought is the Worst in 1,200 Years (npr.org) 113

Shrunk reservoirs. Depleted aquifers. Low rivers. Raging wildfires. It's no secret that the Western U.S. is in a severe drought. New research published Monday shows just how extreme the situation has become. NPR: The Western U.S. and Northern Mexico are experiencing their driest period in at least 1,200 years, according to the new study published in the journal Nature Climate Change. The last comparable -- though not as severe -- multi-decade megadrought occurred in the 1500s, when the West was still largely inhabited by American Indian tribes. Today, the region is home to tens of millions of people, massive agricultural centers and some of the fastest-growing cities in the U.S. -- all in an area where there's less water available than there was in the past, partially due to human-caused climate change.

"We have a society that's relying on there being the amount of water there was in the 1900's," said the study's lead author Park Williams, a bioclimatologist at the University of California, Los Angeles. "But now with the number of water molecules available to us declining, it really is time for us to get real about how much water there is for us to use." Williams looked at tree-ring data from thousands of sites to conduct the research. They sampled data collected from live trees, dead trees and wood beams preserved at Native American archeological sites. The tree rings gave Williams an insight into drought events dating back to the year 800 AD, around the same time Charlemagne was being crowned Emperor of Rome. He identified four other megadroughts in that time period, the most notable being a 23-year drought that ended in the late 1500's. There were hopes during a wet 2019 that the current megadrought was following a similar pattern, Williams said. "And then from summer 2020 through all of 2021, it was just exceptionally dry across the West...indicating that this drought is nowhere near done."

        This is one of the things that I've often wondered. Do those crops need to be watered that much?

        Another thing I've noticed is the lack of preparedness from some of these farms. Back in the day my grandfather had a good size farm, about 40 acres. At first my he had a large pond set up that he would pull water from if the county couldn't provide enough. Then as time went by he added some home made water towers. He would fill them up during the winter when water was plenty, then use it to shore up his water needs during the dry months.

        I've always wondered why this is not standard practice on all farms.

        An another thing while I'm at it. We'll pump oil all the way from Canada to Texas. Why don't we pump water from, say the great lakes to Las Vegas?

        • This is one of the things that I've often wondered. Do those crops need to be watered that much?

          "how much" is poorly defined, but in the last 40 years farms in California have mostly switched from flood irrigation to efficient sprinklers. So the amount of water being used on crops has decreased as water efficient practices have been adopted.

          • Cost is a factor. Where water is plentiful there's no perceived need to conserve. So in the area in Oregon near Calfornia border, flood irrigation was common because it's really cheap. Ie, literally the ground is covered. Mosquitoes everywhere to a ridiculous number. Because they had a lot of water. Turns out, those living and farming down-river were running out of water. Now it's a legal fight (damn native Americans, they should go back to where they ca... oh wait...).

              Yeah. The Midwest invests significant amounts of infrastructure in routing excess water downstream in a more-or-less orderly manner as efficiently as possible, to avoid floods, which are a far more serious concern than droughts here. And since the people downstream (the Great Lakes or else New Orleans) ALSO have overwhelmingly more water than they can use, nobody complains very much if you use more water than you need to use here.

        • Why don't we pump water from, say the great lakes to Las Vegas?

          The main reason is because of the continental divide. We do pump water from Colorado to San Diego.

          • And sometimes water in the river never makes it to the ocean. Arizona is a problem here too; it's a desert and by diverting water from the river they have some big farms there where logically no farms should exist. It's 19th century thinking implemented in the 20th century, but now it's the 21st century and time to think different. Same issue with Salton Sea, where the Colorado overflowed. Farms sprang up but the lake has been shrinking.

            The main reason is because of the continental divide.

            If the pipes are air-tight, then the gravity of the water coming down the other side would largely offset the cost of pumping it up the other.

            • I don't think so, the maximum height of a siphon is ~10 meters.

              Nope, doesn't work that way.

              A pipeline engineer would know better... but most likely you'd just end up with a near vacuum near the peak and a water column that refused to move any higher. I don't think you can avoid the pumping, and that pumping is going to be really expensive.

          • But the difficulty is in addressing it. The conservative farmers will all blame the literal cities of course. But logically there are just too many damn farms for the amount of water. No amount of sympathetic politicians will solve that, and when we get a long stretch of drought years it becomes very apparent that something needs fixing. Some farmers are getting better and more modern with irrigation. But there's still a huge fraction of deniers - no one wants to be the first to declare that their farm

          Not sure about pumping to Vegas, but the difference in water consumption between a drought and non-drought year in California is enough to require 38 billion gallons a day. The largest oil pipeline in the world pumps 77 million gallons a day. Not sure what Vegas's requirements are, but it'd probably require a very expensive pipeline that would only be for drought years. We may get to that point, but the current model seems to be to just force conservation to deal with drought.

            Well, for water, you'd really just need a giant canal with a cover to keep evaporation down, since it's not necessary to contain a pollutant. The problem with Great Lakes -> Vegas is that you have these inconvenient hills called the Rocky Mountains in the way. Well, that and you'd be trying to flow uphill 80% of the way...

          I live in Utah -- and it's not just whether or not the crops need to be watered as much, it's whether they need to be grown at all. About 80% of our water goes to farming, and about half of that is to grow alfalfa. We then export that for a modest profit as hay -- often to fill empty container ships on their way back to China.

          Meanwhile, the Great Salt Lake is shrinking, threatening to turn into a toxic dust bowl, and kill all skiing (no lake effect snow without a lake). The Utah legislature is dominated by conservatives, to they are not concerned about this at all.

    A ghost village that has emerged as drought has nearly emptied a dam on the Spanish-Portuguese border is drawing crowds of tourists with its eerie, grey ruins.

    With the reservoir at 15% of its capacity, details of a life frozen in 1992, when the Aceredo village in Spain's northwestern Galicia region was flooded to create the Alto Lindoso reservoir, are being revealed once more.

    Walking on the muddy ground cracked by the drought in some spots, visitors found partially collapsed roofs, bricks and wooden debris that once made up doors or beams, and even a drinking fountain with water still streaming from a rusty pipe.

    Crates with empty beer bottles were stacked by what used to be a cafe, and a semi-destroyed old car was rusting away by a stone wall. Drone footage showed the derelict buildings.

    We have the capacity to be smarter, but this is going to play out just like any other species of animal in an ecosystem. As far as water, oil and coal goes, it's pump baby pump and drill baby drill until we wither exhaust the resource or we start to overload/collapse ecosystems. The resulting changes are going to be abrupt and largely unplanned.

    The very physical layout of land and sea are changing. The overall composition of the atmosphere is also changing, and with it the climate. I won't even waste time asserting that humanity is drastically altering the second of these processes (despite overwhelming evidence).

    What's happening and why are now secondary questions. What we do about it now is the primary question. We're already committed to some pretty unpleasant changes, perhaps it's time to cut our losses?

Since rainfall shifts with the albedo of the ground, it would seem reasonable to argue that this is shifting atmospheric rivers from where we'd really like the rain to where we really don't need it (say, out to sea or right over Cardiff in Wales) and shifting them upwards (since Archimedes' principle dictates how far warm air will rise and expand).

      Desalination is way too expensive for agriculture (by about 5-10x). And residential water use in CA is only responsible for 10% of the total water use, so it makes no sense to build desalination plants except for a few areas where the regular water supply is unavailable.

          What do you think is going to happen to the price of food and to the economy at Large when vast swaths of our agriculture sector shuts down for lack of water? And do you think the agribusinesses are going to roll over what do you think they're more likely to enforce strict and Draconian measures on consumers?

          Most of the US staple food is grown on the Great Plains, that don't have huge problems with water. The affected areas in California mostly grow cash crops that we'll be able to live without just fine.

          A basic greenhouse can save water use by 60%. Even if that fails, plenty of places in the world have water and are happy to exchange their farmed products for US dollars.

          As for draconian measures, agribusinesses have no power. They're out-voted 9 to 1, even if you count the all the illegals who work on farms (it's not even clear if they have a horse in the race, water costs are paid by the owner, not the workers). The only reason they have any political power at all is because water costs are not on the vot

    • The Pineapple Express is a weather pattern we get every year, it is what we call the weather that starts in S.E. Asia and delivers us warm rain a few times a year in the autumn.

      Most of the rain comes down from the Gulf of Alaska and is colder.

      Nobody here drowns in a flood. That's a regional problem caused by Barney Fife trying to macho his way past an obstruction, combined with a frequent inability to swim. Here, Macho Man just drives the 150 miles over the mountains and around and back to get to the other

      • When a Pineapple Express event dumps 10 feet of rain in less than a month and a half from the equator, it is not the yearly event of which you note.

        True that we get minor variations and once every 2-3 centuries we get the mega-dump.

        But it points out that this is cyclical and has been for AT LEAST 2000 years and that it obviously has ZERO TO DO WITH MAN-MADE FACTORS.

    Much of California's current capacity was designed in the 50's and 60's with capacity for these dry times. Some wiggle room for population growth was there, but not like we have now. Since the 80's our population has nearly doubled. (Source) https://worldpopulationreview.... [worldpopul...review.com] Dams like Oroville are already 50 years old. https://en.wikipedia.org/wiki/...

    As far as global warming, the #1 contributor is concrete, followed by steel ibeams. Not cars, not large ships, but concrete and steel. Yet we keep pushing high density hi-rise buildings made out of the biggest contributor of global warming.

    See it doesn't make sense to me to keep blaming global warming or saying we're in a drought without looking at the cause of both. It's like saying, "People are dying of cancer" but ignoring things like cigarettes. The real issue is as long as politicians are looking to increase tax revenue, and their campaigns are funded by real estate and construction unions, this root cause will never be pointed out.

    What's the solution here? I don't think telling people to move out is going to work, but certainly the strategy should include nuclear power desalination. Fission for now, fusion for the future.

      Other side of the coin is that high density living is typically cleaner in terms of air pollution then lower density, at least on a per capita basis. The higher the population density the easier and cheaper it is to provide effective mass transit to your people for instance.

        Ya but the US is too engrained in tribal politics and land use issues at the moment to do it right. Japan is a monoculture rooted in Daimyo rule. Daimyo's were nothing more than extensions of the Shogun/Emperors will. They did deal with local issues, but if the Shogun wanted something across all provinces, it was the Daimyo's job to make it happen. The peasantry considered the

          What a weird post. Why are your only examples from Asia and why would why would America's political divide matter in the context of individual city zoning?

          I know here in California the folks in Silicon Valley refuse to build up despite ideal economic conditions to do so and most of that region is very solidly blue. In other words, it is most assuredly not a political divide that is stopping the valley from building upwards.

            My experience of talking about this subject. Most arguments for HSR use Japan/China as an example of how HSR is done, but fail to mention what I did.

            >and why would why would America's political divide matter in the context of individual city zoning?
            The USA has a system of states being "Self Governing" and that percolates down a large degree to counties and municipalities. For that matter it even percolates down to individual neighborhoods. That is the tribalism

        Majority of our groundwater use is urban. It also details what the groundwater capacities are. We'd have plenty here if we reduced some of this excess population.

      Yeah, the knee-jerk types that hear "Nuclear Power" and instantly think of Three Mile Island. We really have learned a lot since then.

      Now, to temper that statement a bit . . . remember that both fission and fusion involve radiation - the big difference is you can shut down a fusion reactor quickly and easily. You still have to shield against radiation, your materials are still subject to radiation induced fatiguing, and those materials need to be decontaminated or disposed of periodically.

      Bottom line -

  • Require new buildings to have their own well and sewage system on the same land, so that the water stays where it was (more or less).

    What? No water is reachable from a well? Then that land should not be used and instead be part of a forest or natural park.

    It is time to start only using what the land can provide - it is the only sustainable way.

    Yes many will roll their eyes, but this would limit over use of resources. Too late now but if this had been in place from about 100 years ago the current pr
