Hi,
      You make a very good point.  Many on this board aren't convinced of Global Warming.  I remain somewhat skeptical as well, I don't think all the science has weighed in yet.
      But, the disruption to the Carbon Cycle is definitely real and very measurable.  For instance, Gasoline (at 72°) weighs 6.25lbs./gal.  Gasoline is also composed of about 80% Carbon.  This means that for every gallon of gasoline you consume, you are putting 5 lbs. (80% of 6.25) of Carbon into the atmosphere, think of throwing a 5 lb. bag of charcoal out the window 
every 17-21 miles!
      Now whether this is effecting Global Warming or not is debatable, but certainly it is having 
some effect...
Happy Motoring!... Jim'99
