In this documentary, director Davis Guggenheim eloquently weaves the science of global warming with Al Gore's personal history and lifelong commitment to reversing the effects of global climate change. Gore presents a wide array of accessible and compelling data to explain how pollution has wrought more drastic changes in a few decades thanthe earth has seen since the last ice age. This is, however, not a story of despair as you might think, but rather a rallying cry to protect the earth we all share.

95 minutes. Rated PG.

"In 39 years, I have never written these words in a movie review, but here they are: You owe it to yourself to see this film. If you do not, and you have grandchildren, you should explain to them why you decided not to." - Roger Ebert, Chicago Sun-Times
