In this documentary, filmmakers Daniel B. Gold and Judith Helfand (Blue Vinyl) follow a troupe of self-proclaimed global warming "warriors" on a mission to get the world to care about rising temperatures and melting polar ice caps. Taking a topic that's inherently serious and applying their signature blend of humor and emotional heft, Gold and Helfand advance the environmental dialogue in a surprisingly entertaining way.
