This is an excellent, animated video that covers all the essential issues regarding climate change. We are approaching or at the tipping point, and there are numerous positive feedback mechanisms that lie ahead which will accelerate climate change if we continue on this course.
This video graphically illustrates a major part of the primary thesis of my blog--that capitalism is the engine which, if we allow it to continue, will drive us off the cliffs of climate change and resource exhaustion.

Also the video has been translated into many other languages--see this link.
