This video made one good point, one that we touched on here in that recent climate change deniers thread, briefly.
We are headed towards a "post-carbon" future. One way or another, within the next few generations all of the natural carbon stores on earth will have been mined and burned, and we'll end up using some system of alternative energy production.
Ideally, we manage this transition intelligently by slowly phasing in alternative energy sources gradually. Even ignoring the environmental consequences of putting every bit of natural carbon on planet earth into the atmosphere, the purely economic impacts of the transition will be complicated.
