      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.

      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,"
    • Peter Nguyen
      Peter Nguyen on 22 Oct 13
       
      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.

  • 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.

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'
