I'd just like to say
For those of you who are lecturing about this movie need to calm down. He isn't trying to disprove it, he just doesn't believe in it. Don't rub your beliefs in everyone else's face, this movie doesn't.
And don't believe everything you see on the TV. Not saying global warming isn't true, I'm just saying that it's possible. I have read in William Coopers book "Behold a Pale Horse" that global warming is a hoax, and if anything we will have gone through an Ice age before anything. Read the book yourselves.
