Global Warming / Al Gore's pseudo sceinice

Common sense should tell you that Al Gore is just plan wrong. I looked all these things up about global warming according to Gore, like the sky is not falling video/ essay competition, 800 years ago warming happened and about the MIT professor that got his grant pulled because he failed to show warming over the past century. I felt that if you would check out the school that your child would be attending and check out the teacher that would be teaching your child, that you naturally check global warming according to Gore, but I was wrong. I guess it would do me no good to mention, that the polar bear picture on the iceberg was taken in Aug. and not more than 2 miles from land and polar bears can swim 60 miles with no trouble. I guess it would do me no good to mention that all the ice that melted has came back and in some cases more or the fact that there are more polar bears now then when they had them put on the watch list. All these are facts, if you care to look them up. It is hard for me to believe that most people that would look thing up, would not look up something that will have a BIG impact on your tax dollar. Gore is pushing for not only cap-n-trade but a carbon tax as will. What brothers me the most CO2 does not cause heat but heat causes CO2 to rise and no one has ever tested what the impact of a rise in CO2 would have, since CO2 only makes up 1/10th of one percent greenhouse gases. AL Gore said ( if you think I am doing this for money you do know me) and he may not be doing it for money but he sure is making a lot of it. To Al Gore, money may not be every thing but I am sure, like most of us, it bets what ever in second. If we burn to a crisp in 20 to 30 years, I was wrong and old Al was right but Dec. 21 of 2012 is coming fast, so 20 or 30 years down the road will not matter anyway.
Thanks
