Which 2006 documentary about climate change starring Al Gore won an Oscar?

The 2006 climate-change documentary starring Al Gore that won an Oscar is An Inconvenient Truth.

Directed by Davis Guggenheim, the film adapts Gore’s multimedia presentation about global warming into a cinematic lecture and personal campaign. Gore uses graphs, photographs, scientific findings, and dramatic visual demonstrations to explain rising greenhouse-gas concentrations and their potential effects on the planet.

The presentation grew from talks Gore had been giving since the late 1980s. Producer Laurie David encountered one of those presentations and helped develop the idea of turning it into a documentary. The film premiered at the 2006 Sundance Film Festival and became both a critical and commercial success.

An Inconvenient Truth won two Academy Awards: Best Documentary Feature and Best Original Song for “I Need to Wake Up.” A common mix-up is confusing it with An Inconvenient Sequel: Truth to Power, released in 2017. The original film helped bring climate science into mainstream public discussion, although some of its claims and educational use later attracted controversy.
