I'm still not sold on it being man made. And yes the climate is changing. There have always been fluctuations in the weather and man hasn't had anything to do with it.
But to say it's man made and the only way to fix it is by spending money, that's where it loses it's argument with me. Once people start cashing in on a supposed catastrophe it loses all credibility.
The very same scientists who tell you the weather has always had fluctuations are the very same ones telling you that there is a larger increase in global warming due to man made actions. I guess if you already have your mind made up, you'll just pick and choose what you want to believe.
