Watch Bono, Paul McCartney, Camila Cabello Star in Trailer for Al Gore's 'Inconvenient Truth' Sequel

Al Gore gathered an impressive cast of A-list musicians to come to bat for his latest opus on climate change.

An Inconvenient Sequel: Truth to Power -- the sequel to his 2006 Academy Award-winner An Inconvenient Truth -- hit U.S. theaters earlier this month, and today (Aug. 10) Paramount Pictures unveiled a star-studded trailer. Below, watch Paul McCartney, Bono, Pharrell Williams, Camila Cabello, and many other famous actors and musicians speak up about the perils of climate change.

"The poorest of the poor are furious because they're hit first and worst by climate change," says Bono. Quips Pharrell (another veteran of this kind of activism), "We have one planet that we live on -- we ain't on Mars yet. Until we get there, I'm inconvenient."

An Inconvenient Sequel premiered at Sundance Film Festival back in January, and was released in U.S. theaters on Aug. 4.
