I watched the trailer, and truthfully, I find the presentation a little on the boring side. Global warming does appear to be a real threat to the worlds economy, and could turn the US into a third world nation, that's not much of a stretch, we are going the way of the Soviet Union now, with a huge military bankrupting the country. The difference is, when the USSR dissolved Russia had plenty of oil.
