Yeah, so it may not be true… like branes, it is a theory the explicit truth of which is hard to prove.
However, if it is a scam then it is a necessary scam. Governments and Big Businesses are using it, blatantly, to beat themselves and each other into reducing dependence on oil before oil skews the economic power balance of the world – or rather, before it re-skews it to favor the predominantly islamic parts of the world as opposed to being skewed in favor of us in the old “western bloc”.
So, global warming skeptics, suck it up. Nobody cares if it’s a scam. And neither should you, unless you’re arabic, in which case I say to you “Go and champion your truth”, in the spirit of fair being fair.
