I have watched Al Gore's documentary, An Inconvenient Truth, and found it very believable. But tonight I was watching another video, The Global Warming Swindle, on Google Video. This documentary, which was made for British TV, was also very believable.
Al Gore showed us a graph that seemed to indicate that carbon dioxide levels and the earth's temperature went up and down together, leading us to believe that the increased CO2 was causing the higher temperatures. However, in The Global Warming Swindle, we are told that the temperatures went up first, THEN the CO2 increased a few hundred years later.
Apparently, the greatest cause of global warming is....the sun. Sounds obvious, doesn't it? Increased solar activity has historically resulted in a warmer earth. Our oceans are the main producers of carbon dioxide but, because of the size of the oceans, changes are very slow. The video stated that it cannot be human activities of the last 60 years that are causing current global warming and weather changes, because the cause of these effects probably occurred hundreds of years ago.
It really makes me wonder what to believe, and I feel that once again we are all being manipulated by the people who are funding one side or another. Obviously, there's an agenda here, and I think we have to follow our own intuition as to what is right for us.
