It's no understatement to say that the 2006 documentary "An Inconvenient Truth" changed the direction of public policy. And in fact, that's exactly what failed presidential candidate Al Gore intended the film to do. Fortunately for him, he found a willing audience of Hollywood celebrities and left-wing media outlets to uncritically promote his ideology and activism.
