CLIMATE

  Let's define 'weather' and 'climate'.  Weather is short term, as in
  what's happening today, this week, or possibly a couple months.  Climate
  is long term, such as 20, 50, 100, or even 1000 years.  The more decades
  or centuries you have to study, the more accurate climatic prediction
  will be.  There are known and various 22, 44, and 98 year climatic cycles.   
  But overall, scientific studies show few facts concerning long term
  climatic changes.  Some of it is speculation, and much of it is theory
  based on computer models.  These computer models are created by scientists
  who enter their own variable conditions, or their own information based on
  their findings.  An example of this is carbon dioxide buildup in our
  atmosphere.  Mankind is in fact adding it with our current lifestyles.
  Scientists have tested what additional carbon dioxide buildup does to a
  'test tube' simulated Earth atmosphere, and they of course record their
  findings.  Those findings are entered into the computer models which
  have created all kinds of diverse results.  Some show that global warming
  has already started, others show that additional carbon dioxide will
  actually cool our planet.  Remember, computers are not always correct.
  Their results are only as good as the information entered into them.
  So are these findings accurate to real-world climatic changes?  Which
  scientific study do you believe?  That is hard to say, but the true  
  answers are probably somewhere near the center.  Although that could prove
  to be wrong too.
  Some people have even stated that any potential global warming that might
  occur could actually benefit all of mankind.  They say it would increase
  farming yields and end world hunger.  I doubt this could actually be the
  case because if we cannot control it, how can we possibly benefit from it?
