I will have to have some evidence, and not just theory before I jump on the global warming bus. In the seventies it was global cooling on the same scale as the global warming hype now. We were all going to freeze to death. I am pretty sure everyone here is old enough to remember the ozone hole scare of the 80's-90's. They said we were all going to burn up because we were destroying the ozone. Now they know that the hole is natural, and supposed to be there to regulate the temperature/pollution levels. It has been the same group of people that has instigated all of these scary scenarios. If these people had their way by now we would be dead. They had suggested firing a nuclear warhead at the moon so the explosion would slightly alter the earth's orbit and move it a little farther from the sun to fight global warming. During the ozone hysteria, they were talking about flying jet fighters back and forth across the hole to "sew" it up. So far they are 0 for 2. I need some facts and not theory. The only facts so far are only to support their theories just as before.
