Many don't remember that the esteemed Mr Al Gore's previous quest was the hole in the ozone layer and the emenent demise of life on earth. His rant led to the ban of freon refrigerant. CFC refrigerent (freon) was the best refrigerent developed for refrigeration and air conditioning, now that we are forced to use substitutes the costs of keeping stuff cold has become more expensive due to higher energy costs to operate the equipment. Of course this means more co2 developed at the power plant.
This is a long read but it should add to the understanding of Mr chicken little, the sky is falling Gore. Before the ban all aerosols such as hair spray, paint,window cleaner were propelled by freon gas. Now all of that has been replaced mostly by co2 maby its a conspiricy.
The irony is that then as now many sicentists were not convinced of the danger.http://www.thenewamerican.com/tech-main ... eon-frenzy
