The fact that the socialists have tied their wagon to this issue so tightly, used it to attack oil and gas production and use, taxed and regulated many businesses to near extinction, forced automakers to choke their cars with things that make them run bad and inefficiently, to justify putting 10 percent corn in gasoline, carbon credits, given away billions to alternative energy outfits that took the money and disappeared, and on and on, does nothing for the believability of the underlying theory.
You cannot believe them on almost any of their cockamamie theories, so why would anyone believe them on this one? Science (science unfettered by political agendas) certainly has not proved it.
I certainly support doing our best to not put vast pollution into the air (and water), but not to the point we cut our own throats or go back to horses, or line their pockets with vast amounts of our income in taxes so they can continue spending for all manner of foolishness and waste.
Can't go back to horses. Horses fart, remember?
