The Inconvenient Truth

An Inconvenient Truth is a 2006 documentary film directed by Davis Guggenheim about former United States Vice President Al Gore's campaign to educate citizens about global warming via a comprehensive slide show that, by his own estimate, he has given more than a thousand times.An Inconvenient Truth focuses on Al Gore and on his travels in support of his efforts to educate the public about the severity of the climate crisis.

An Inconvenient Truth is an example of an expository documentary because it relies on verbal commentary and argumentative logic to make its strong case for prevention of global warming.
