Speaking of opinions, here's mine:
People will believe in what they want to... If they have "faith" in Al Gore and company - they will believe in a man-made crisis of Global Warming. Their "faith" will fuel their personal Religion. If you would like more understanding of how Panic and Crisis can make people some money (there really are people making lots of money on this "problem") -- please read Michael Crichton's State of Fear. It is fictional, but he has actual data from NOAA and other sources that show how folks can easily manipulate real data into something that supports their viewpoint. "Global Warming" is Amazing Stuff for Gullible People. Talk about Smoke and Mirrors!
Do you want some real Truth? Here is some TRUTH for you -- Our Sun and its 11-year Sun Spot cycle actually determines what our weather and climate is going to be. Humans have very little impact in forming the climate. CO2 levels in our atmosphere are completely BOGUS. All this talk about Carbon Levels and Carbon Footprint is complete and utter nonsense. Free Carbon is around 0.02% of what is in our atmosphere. That all... and it hasn't really changed levels in the last 100 years. Instead -- Take a look at Water Vapor levels in our atmosphere - that's correct - I said Water Vapor. Our Sun and Water Vapor are the 2 most powerful determining factors in our climate and weather.
Bottom Line is -- do your own research. If you rely on Politicians, Lawyers and the Media (PLM) to format your opinion about this situation -- all is lost for you....
