I hope some of yall are kidding. Global warming does exist......its not some elaborate scam by the government.
Warming in the atmosphere is cause by the increased amount of co2 in the atmospere. Average tempatures are up and co2 levels are higher than they have been in the last 600,000 years. Believe it, don't believe it.........scientists believe it and I'm not one so I have to take there word for it. Scientist don't dispute global warming, politicians do..........go figure. If your under 50 you will see changes in your life time to reduce the amount of co2 in the atmospere.............bank on it my fellow horn chasers
