COMMENT: Mr. Armstrong; I came across this guy Richard Lindzen and it struck me he was asking people the same question about the Second Law of Thermodynamics. He concluded that very few people who appear to be scientists or educated can even answer the question but still profound to be experts on Global Warming. It is impossible to argue for Global Warming if you cannot even describe what is the Second Law of Thermodynamics.
Thank you for opening our minds.
