It's underneath most of Nebraska's farmlands, and it provides crucial water resources for farming in Colorado, Kansas, Oklahoma and even New Mexico. It's called the Ogallala Aquifer, and it is being pumped dry. See the map of this aquifer here: http://www.naturalnews.com/images/Ogallala.g... Without the Ogallala Aquifer, America's heartland food production collapses. No water means no irrigation for the corn, wheat, alfalfa and other crops grown across these states to feed people and animals. And each year, the Ogallala Aquifer drops another few inches as it is literally being sucked dry by the tens of thousands of agricultural wells that tap into it across the heartland of America. This problem with all this is that the Ogallala Aquifer isn't being recharged in any significant way from rainfall or rivers. This is so-called "fossil water" because once you use it, it's gone. And it's disappearing now faster than ever. In some regions along the aquifer, the water level has dropped so far that it has effectively disappeared -- places like Happy, Texas, where a once-booming agricultural town has collapsed to a population of just 595. All the wells drilled there in the 1950's tapped into the Ogallala Aquifer and seemed to provide abundant water at the time. But today the wells have all run dry. Happy, Texas has become a place of despair. Dead cattle. Wilted crops. Once-moist soils turned to dust. And Happy is just the beginning of this story because this same agricultural tragedy will be repeated across Oklahoma, Nebraska, Kansas and parts of Colorado in the next few decades. That'

      I would think around this time, we would have already have come up with flying cars and life spans. What can future scientists do to turn global warming around?
  • great temperature increases expected in the Arctic.
  • first to experience unprecedented temperature changes surprised scientists who weren't involved in the research.
  • greatest variety of life and biodiversity and the poorest people in world live in the tropics, and the new climate shifts will be outside their parents' and grandparents' experience."

      Wouldn't part of Africa be affected? They live around forests and desserts!
  • fewer opportunities for plants and animals to do that
  • Given that, there's a very, very severe worry about what this will do to species in the tropics,"

      I would believe that animal extinction would mostly occur. Then we can't eat meat anymore. Veggies for life until plant life is extinct. Might it turn into cannibalism?
  • animals with shorter life spans will have more generations pass through a given time period
  • gives them more chances to evolve and adapt to new conditions.

      Will the polar ice caps be affected by melting? How will living things survive?

  • Although organisms all over the world will have to find ways to adapt to higher temperatures, animals in the tropics are particularly vulnerable, researchers said. Conditions in the tropics stay in a narrower range than in other places on the planet, so it takes a smaller shift to put creatures in peril, said biologist Eric Post, director of the Polar Center at Penn State.

      Could this make some animals extinct?
  • "The optimistic way to look at this is that taking steps to reduce emissions is buying us time — for species to adapt, for human societies to change and to come up with technological advancements," said study coauthor Abby Frazier, also a graduate student in geography at the University of Hawaii. "It lets us put on the brakes. If you were about to get into an accident, wouldn't you want it to happen at 20 mph rather than 80?"

lingro: America's breadbasket aquifer running dry; massive agriculture collapse inevitable - 0 views

  • Without the Ogallala Aquifer, America's heartland food production collapses. No water means no irrigation for the corn, wheat, alfalfa and other crops grown across these states to feed people and animals.
  • This problem with all this is that the Ogallala Aquifer isn't being recharged in any significant way from rainfall or rivers. This is so-called "fossil water" because once you use it, it's gone. And it's disappearing now faster than ever.
  • Dead cattle. Wilted crops. Once-moist soils turned to dust. And Happy is just the beginning of this story because this same agricultural tragedy will be repeated across Oklahoma, Nebraska, Kansas and parts of Colorado in the next few decades
  • "There used to be 50,000 head of cattle, now there's 1,000,"
  • A large percentage of the food produced in the United States is, of course, grown on farmlands irrigated from the Ogallala. For hundreds of years, it has been a source of "cheap water," making farming economically feasible and keeping food prices down.
  • The problem is called aquifer depletion (http://www.eoearth.org/article/Aquifer_depletion), and it's a problem that spans the globe. It means that today's cheap, easy food -- grown on cheap fossil water -- simply isn't sustainable. Once that water is gone, the croplands that depend on it dry up. Following that, erosion kicks in, and the winds blow away the dry soils in a "Dust Bowl" type of scenario.
  • This has caused food prices to skyrocket, leading directly to the civil unrest, the riots and even the revolutions we've seen taking place there over the last few months.
  • Based on the huge demand for this event, we have decided to roll out a second preparedness event in April, focused on food preparedness and security. Watch for an announcement on that soon.
  • From living in South America and producing quite a large amount of food there, I have a fair amount of experience on home food production,
  • such as the drying up of aquifers is that home food production is going to become a critical survival skill.
