According to the predictions of NASA, the western United States will encounter mega-droughts in the second half of the current century, which will be the worst seen in 1,000 years. The researchers opine that the drought may continue for multiple decades and will probably be more severe than the one which had hit the Pueblo civilization of the previous millennia. The research team mentioned that the Southwest and Central Plains of the U.S. will be affected by “Unprecedented drought conditions” after 2050. The research has been detailed in the journal Science Advances.

NASA’s Benjamin Cook, an atmospheric scientist and the study’s lead scientist commented “Nearly every year is going to be dry toward the end of the 21st century compared to what we think of as normal conditions now.” The research team has estimated that there is an 80 percent chance that a mega-drought will hit the West in the latter part of the century, continuing for 35 years or longer. The regions which will be worse affected include Arizona, Arkansas, California, Colorado, Dakota, Iowa, Kansas, Louisiana, Minnesota, Missouri, Nevada, New Mexico, Oklahoma, Texas and Utah. Cornell University researcher Toby Ault suggests that the predicted mega-drought will make water a ‘precious’ commodity in these regions.

The prediction has been made on the basis of tree-ring records and a series of intricate computer simulation models. The researchers also considered the rate of carbon dioxide release into the atmosphere for making assessments. Tree ring studies have revealed that between 1100s and 1200s a number of mega-droughts affected the Southwest and Central Plains. Although during the predicted mega-drought much of the west and Central Plains will receive scanty rainfall, the major issue will be the heat. Researchers opine that high temperatures will result in high evaporation rates and drying out of soil. The situation will then worsen with the air growing hotter.

    Hmmm, so they’re predicting longer droughts for the Southwest. Well then, if the equal and opposite law holds true, then there will also be areas where rainfall downpours will become much more prevalent, since this excess rainfall has to go somewhere, and that can be as bad as droughts.

    According to many computer models, east of the Mississippi will become like a rain forest where it is already forested, with almost daily rains.

    But of course no rationing of water or paying now
    to find ways to live with 90 percent less water will even be attempted until it
    is far too late. We see what is coming
    and just throw the dice anyway. We are
    not in any regard practical or logical in large groups. We have not changed our ways since other
    smaller civilizations were wiped out by drought. The gadgets and science are all trappings
    over the same primitive people.

  • Brian Stump

    What I find more telling is author bios and the relationship between that and spin on story.
    In this case “worshipper of life” produces/covers gloom and doom stories. Well, at least there’s no direct reference to global warming.

  • Pete

    Here we go again, as soon as it starts to get warm the liberal extremists crawl out from under their rocks, I remember when the liberal scientists said in the 70’s or 80’s about a new ice age that would shut down most of the US.

  • bdcstrong1

    Global Warming must be true if they used 17 different climate change models, wow who would have thought. Just think, every 500 years or so the Earth changes and we experience excessive heat and dry periods in certain parts of the world, wow who would have thought. Bottom line is snow, droughts and floods have happened before on Earth and they will happen again… But keep that Hockey stick at the ready!

  • bdcstrong1

    Sounds more like a jungle…

  • Mike Prongué

    The knuckle-draggers still call it “global warming” and then label anything they can’t understand as “liberal”. It is called “climate change” and almost every scientist under the age of 80, not on the Koch brother’s payroll accepts it’s real. The weather is not liberal or conservative. It’s happening whether you believe it, or not. So if being liberal means being aware of science, then that’s not only a good thing, it’s a great thing.

  • bdcstrong1

    The climate does change, so what? You don’t need to be a scientist to realize this, so what does the changing climate have to do with CO2 levels…?

  • Mike O’Brien

    So they used the output of global climate models, that have FAILED over the last 20+ years, as input to their untested drought model and they call the results ‘science’? They would have gotten just as reasonable results with Tarot cards.

  • Mike O’Brien

    Would those be the cliamte models that have been wrong for more than 20 years?

  • bdcstrong1

    or the Farmers Almanac…!

  • Tony

    This in an extremly uneduated understanding of what’s happening. Human’s are increasing the CO2 levels and are changing the environment. The Science and the evidence is well published. If we continue to play dumb – there will be serious reprocussions.

  • lapazjim

    Obama to Americans-“Climate change is the GOP’s fault !!!”

  • Tony

    Please stop. This has nothing to do with liberalism or conservatisim. The Koch Brothers would like you think otherwise because it impacts their bottom line.

  • bdcstrong1

    Where is the correlation between warming, wet/dry weather and CO2 levels? When has the Climate NOT Changed? I don’t want to see computer climate change software models which MAY project a warming trend, that is NOT science, just computer software programs! What about China and India, are they doing anything? Well China may do “something” in 2030… This is called smoke and mirrors, STOP the spin! AS Gruber would say, “American voters are stupid”. The facts are that the Global temperature has increased 0.8% over the last 100 years and that’s a fact!

  • bdcstrong1

    But, your forgot to mention MIT professor Gruber…

  • Jason Lalli

    Are you saying CO2 does not function as a greenhouse gas?

    Let’s argue facts:

    1) CO2 levels are increasing through man’s actions

    2) We only have one atmosphere, and no cost-effective way to undo what we are doing now

    That’s it. Climate change, no climate change, warming, cooling…it is difficult to predict the future, but it doesn’t take a rocket surgeon to realize we are running a global experiment to unknown ends with no means of stopping it.

    That’s dumb.

  • Pickee

    The climate has been changing since climate existed. In fact, the climate has changed so much through the millennia that you could say that overall the climate never changes because it always does.

  • Pickee

    The rational thing would be to limit or end immigration in order to conserve what little water supplies will be remaining for those who are already here. Of course, we will instead keep the borders wide open and our children and grandchildren will suffer the consequences.

  • bdcstrong1

    CO2 is a natural byproduct of humans as we exhale it… and trees love CO2, what are you against trees? Methane as a byproduct, is 10 times worst than CO2, should we ban cows?

  • sickofspin

    Alarmism.

  • sickofspin

    You’re buying into propaganda.

  • sickofspin

    Elitist, alarmist, propaganda talking points. Now THAT, is uneducated.

  • realisticview1

    Those of you with political agendas are laughable.

    This is about practical proactive measures to prepare for what is coming, or is already happening. Finally Socal is building a desalinization plant. As long as the population of the world continues to increase then natural resources will become scarcer. It’s simple math.

  • bdcstrong1

    That’s what they said in the 1950’s and guess what we are all still around…!

  • PalmDesertRat

    Many are arguing about the drought problem but I never see any proposed solutions for it. I can think of three or four, all of which would require a lot of science and investment.
    Water desalination, transport of water by pipeline, transport of humid air, manufacturing of water.
    My favorite is manufacturing water: it’s only hydrogen and oxygen.

  • bdcstrong1

    Yes they would, wonder how Al Gore feels…?

  • realisticview1

    Still around, but quality of life has not improved.

  • rattboo

    Hey Mike O’Brien, you boldly proclaimed:
    “So they used the output of global climate models, that have FAILED over the last 20+ years” How have “they” failed? Who are “they”? Links to your sources please. Do you call your post science? No links, no science. No credibility. You may just as well have claimed that the earth is flat, and the sun rotates around the earth, at least that would be something people could laugh at.

  • Jason Lalli

    You can’t honestly think your “counter-argument” is worth discussing.

  • rattboo

    bdstrong1 says: ” The facts are that the Global temperature has increased 0.8% over the last 100 years and that’s a fact!”

    So, bdstrong1; you talk about “facts” , and then you only mention 1 of them. Where are the other facts and what are they; and Where did you get “that” one fact?

  • Mike O’Brien

    No.

    The fact that CO2 is increasing is well known.

    The fact that global temp has risen since the 1700’s is well known.

    Whether the two are connected and how much more climate will change and in what ways are all speculation.

  • Mike O’Brien

    Hey rattboo, sure.

    They have FAILED because they temperature increases they predict are off by a factor of two or more. They have FAILED because the characteristic warming of the troposphere they predict has not happened. They FAILED because the decrease in Antarctic sea ice they predict has not happened.

  • Kalohe59

    Mega droughts like the ones between 1100s and 1200… So these are a natural cyclical occurrence just like global warming? Yet THIS time we need to avert a crisis through income redistribution…?
    Sounds like a liberal ponzie scheme once again.

  • rattboo

    Since your post is not science, link to your sources, please. No links, no science, no credibility, even a fool can see that; however, you do have a right to your opinion. If you are a scientist, then what is your degree, and what were the studies you did?

  • Mike O’Brien

    No science required, fool. The models make predictions that anyone can read. Those predictions don’t match what has really happened thus they fail. If someone predicts that team A will beat Team B by 20 points and Team B wins by 5 points it doesn’t require science to know the prediction failed.

    Sorry that you have no common sense.

    And thanks for proving again that you can’t read or comprehend simple English.

    People need to learn how to use less water, period. The days of long showers and wasting water on lush lawns should come to a stop. Especially in the west. Look at how much Lake Mead has dropped. It’s only a matter of time before Hoover dam will no longer be able to function as a hydroelectric dam because the water level will fall below the intake stacks. It amazes me that politicians know of these problems, yet they will sit back and do nothing until it’s absolutely too late.
