The video below is a great synopsis of the evidence that the activity of the sun has much more to do with our climate than CO2.
Also, I personally remember in the mid 1970s that “scientist” were warning that we were possibly heading toward another Ice Age. Many people who believe in catastrophic man-made global warming now deny this, but in addition to my memories, the video below documents it. Obviously, if in the 1970s we were worrying about a coming Ice Age, and a mere 40 years later, another cadre of “scientist” are pretending that we are heading for global warming, and that we have been for a century…well, let’s just say that there is a serious lack of credibility on their part.
