I just can't believe that carbon dioxide is a cause for warming of any temperatures anywhere. It only comprises .038% of the atmosphere! Of that, only 3% can be attributed to mankind. Laying out the atmosphere gases on a football field, the first 78 yards is nitrogen, oxygen is the next 21 yards. Thats 99 yards, the final yard, except for 2 1/2 inches is argon. Of the final 2 1/2 inches 1.37 inches is carbon dioxide. Of that 1.37 inches, man contributes about the width of a dime standing on edge! So a dime standing on edge on a 100 yard football field is our contribution to the so called greenhouse effect. Sorry, not buying this one! Is the weather changing? Yes. Is it changing enough for us to notice in our lifetime, doubt it. I do know the world has been changing since the beginning of time, and will continue to change to the end. When you consider all the forces that drive our climate, the sun, the moon, the axis of the earth and the wobble of the axis, and others we may not know of, or at least know their effects on the weather. Carbon dioxide is not one of them. It is just a rouse to scare the public so the politicians can tax it! Period! A good book with tons of info is Climategate by Brian Sussman. It comes with footnotes so you can check his info, something Al Gore does not provide!
