Al Gore Said it First

This video explains how Global Warming, driven by greenhouse gasses, can be powerful enough to shift global habitats as the temperature changes just a few degrees.  The meteorologist made a good point in pointing out how species can adapt to a climate change, but in this case it may happen too quickly for the world to respond fast enough.  The vast areas that would be left devoid of water because of excessive global warming are a testament to how bad this problem can get.  The fact that this study predicts climate shift and entire climate zone's disappearances as early as 2100 makes me want to get up and do something now, because my children will be alive when that happens.  I'd like it if they could someday visit the plains of Africa, rather than have nothing but old pictures of them.
  As for the African species themselves, what happens if these midland species can adapt? Lions and zebras somehow moving north into the European plains could cause quite a few problems for the populous living there.  They will most likely be wiped out by humans before causing any real agricultural problems, or safety hazards, but still, how heartless does that make us?  The West Nile Virus, carried by mosquitos, would also become a huge problem, and not so easily stopped.  if climate shift pushes zones further north, areas formerly too cool for these mosquitos to thrive would become warmer and muggy, perfect for reproduction.  A lot of people would be sick with WNV, or Malaria.  Insect spreading could become a huge problem in general, and once locusts make their way out of drier climates, there goes the United States profitable agriculture industry.
   Unless we start doing something now, or at least find out how to live with it, this climate change and everything affected from it will become our children's problem.  I'm not too cool with that.
