Let's bring this back on track.
Freon has to do with the hole in the Ozone layer, not global warming. It is now much less of a problem thanks to regulation of the Freon and other CFCs. This was mentioned in the movie as an example of how large scale global problems can be addressed through united action.
Al Gore may not be a scientist, but I bet he knows a lot more about global warming than you do. What motivation do you think he has to lie? How will he make money through misrepresenting environmental science? Of course, given ML's point about the overall agreement in the scientific field, I doubt he's doing much misrepresentation.
Along the same point, you make accusations of scientific groupthink. But isn't there tremendous motivation for a scientist to prove everyone else wrong, to prove the contrarian position, to upset conventional wisdom; they don't get the recognition and grant money by confirming what everyone else thinks.
Any attempt to explain complex scientific information to the public demands a middleman, someone to compile information and present it in an easily digestible form. For example, a movie or slideshow. So who would you trust to do that fairly?
If anyone who believes in global warming is a liberal, and any liberal will misrepresent global warming information, therefore global warming does not exist.
That seems like poor reasoning.
One middleman who takes great pride in being a contrarian is Greg Easterbrook. He has long doubted global warming and has argued in favor of intelligent design. Now he's changed sides. Read his opinion piece here.
And finally, here are some charts with estimations of global temperature over the past 2000, 1000, and 150 years. Does the slope of the line in the last 150 years seem rather steep to anyone else?
