Greg Craven, a high school teacher created a youtube video back in 2007 about climate change and how to decide what we should do about it using what he calls a 'decision grid'. Using decision grids he allows us to see what the different future outputs could be depending on what happens on Earth through the populations as well as the possibility of climate change happening. A sequel to this video can be found here.
He also has a book!
