Documentaries have the specific intent of conveying a reality to an audience, promoting certain actions or responses. Davis Guggenheim’s An Inconvenient Truth is an issue-driven documentary film released in 2006, placing it within today’s environmental crisis. The subject of the film is global warming and depicts former United States Vice President Al Gore’s global slideshow tour educating his audience of this.

The same glacier, today.” The use of juxtaposition exaggerates a worldwide message that is depicted through the collection of ‘then and now’ photographs.
