An Inconvenient Truth (2006)
The award-winning documentary of Al Gore's slide show (as he calls it) about the negative impact of global warming has upset many. Some are upset at what the scientific findings mean for the future of life on this planet. Some are upset that the government has largely ignored these findings for years.
Another group is upset that there has been so much attention paid to the idea of global warming. They say that the Al Gore and others like him are alarmists, misleading the American public about a problem that isn't really a problem. They say that global warming is a myth. Well, I really hope they're right, because I like the idea that An Inconvenient Truth is false a lot more than I like the idea that it's true.
Watch the movie. Get upset.
