An Inconvenient Truth is more than a documentary record of Al Gore's dynamic traveling slide show about global warming. It's a spiritual autobiography and a call to conscience that rests on Gore's credibility both as a student of ecology and an individual engaged in the key conflicts of his time. Its knockout success is a testament to Gore's eloquence and humanity and to the dexterity of his director, Davis Guggenheim.
Gore's lecture, the core of the movie, demonstrates just how to popularize science. His spot-on visual and literary analogies and audio-visual aids bring a long view of our destiny into telescopic clarity. He calmly lays out how post-industrial human practices have been heating the atmosphere and altering climate at phenomenal rates. His tone is apt: He's elastically urgent. He doesn't need to overdo the gloom and doom - the before-and-after images he unveils of thriving and eroding shorelines and icecaps are sufficiently alarming.
