To my knowledge we've already gone past the point of no return (ie. if every human being on the earth cracked out a guitar and lit up a joint global warming would still destroy the earth), so exactly what point is there in altering our life styles for the sake of preserving our descendants? Sooner or later a generation is going to be wiped out along with the rest of the planet, what difference does it make how many generations manage to last? Anything anyone of them do will be equally worthless in the long run. Whether it happens in 200 years or 2million years it's effect will be equally indirect. No matter when it happens the generation that has to deal with it will still be pissed at their ancestors no matter how much they tried.
In sum: Believe it's happening, believe media is as misleading concerning global warming as it is every other controversial issue, I don't think we should switch to greener energy, I don't think there's any doubt about whether it's being pushes into society, and I'm not a scientist.
