Former vice president Al Gore shares his concerns on the pressing issue of global warming in this documentary. A long-time environmental activist, Gore first became aware of evidence on global warming in the 1970s, and since leaving public office he has become a passionate advocate for large- and small-scale changes in our laws and lifestyles that could help alleviate this crisis. An Inconvenient Truth records a multi-media presentation hosted by Gore in which he discusses the scientific facts behind global warming, explains how it has already begun to affect our environment, talks about the disastrous consequences if the world's governments and citizens do not act, and shares what each individual can do to help protect the Earth for this and future generations. An Inconvenient Truth was directed by Davis Guggenheim, a veteran documentary filmmaker who also has an extensive background in episodic television.
