Of course, Al Gore does not explain that within the past several years, one of may issues is that the earth expels green house gases naturally. Volcanos expel dust particulates ,sulfer dioxide, and
other assorted contaminates into the atmosphere. Not to mention there are methane hydrates that emerge from deepsea deposits.
About the polar bears dying off. those that die were from severe storms, and there population has increased ever so slightly over the years.
I for one realize that earth's climate fluccuates a couple of decades ever so often.
Al Gores prize was won merely as a political tool which is not a very honorable action.
Except you're omitting the very relevant fact that human activity produces much more CO2 than natural processes ever did. Don't delude yourself.
Tom Brokaw said it is real, so therefore it is. Because I say so. Also, if you're a real libertarian, you'll realize that "the market has spoken" by giving Gore's film a real success in the theaters, ipso facto magico, global warming is real.
