It is difficult to debunk information like that. It is even more difficult to prove it.
Don't get me wrong. I do belive in global warming and the rest, but to me, information like that is almost as strange as that produced by the global warming deniers.
The real problem I have with you friend though, is that they make their living by telling you the obvious without having a clue as to prescribing a real alternative. Electic cars you say or even fuel cells. Guess what you have to you to generate the electricity to charge the batterys or worse to separate the hydrogen from the oxygen?
