The Force of Destiny: The Science and Politics of Climate Change (2004)

Film makers, scientists, researchers and law makers discuss the current understanding of environmental issues, potential future problems and the concept of "climate change", various modern calamitous events and developments as well as their ramifications, possible effects, methods that can be taken to change matters and movements in that direction, efforts from US lawmakers and our society's legacy. This documentary presents a disturbing look at the situation. It certainly doesn't paint a pretty picture about the current situation and prospects for the future, especially since the participants don't seem all that optimistic politicians and corporations will do what's necessary.
