Certainly some were concerned with global cooling. Plenty of articles on the subject but in reality, it does not really matter. My point is that no one really knows. There has been no global warming for the last 15 years, has there? And we have no idea what cycle we are in do we? The entire global warming/climate change scam is exactly that...a scam. And idiots like Fat Al Gore have cashed in while the ignorant who buy this religion waste their enthusiasm, emotion and funds on nonsense. Any Chevy Volt owners out there?
