I firmly believe that carbon dioxide is one of the main causes of global warming but politics has distorted information to the point where most people do not know what to think. The most reliable way to measure sea level is using satellites and since 1992 measurements show a rise of 3 mm per year. That equates to one inch per 8 years or one foot per 100 years. There are many articles on the Internet about the rising sea levels and this is an example: the sea level here has risen 9 inches over the past century and is predicted to rise at an accelerating pace by as much as another 6½ feet by 2100. Even the most conservative scientists anticipate a rise of at least 2 feet by 2060. Using the satellite data the expected rise by 2060 would be 5.4 inches not 2 feet and by 2100 the rise would be 10.2 inches not 6 and 1/2 feet. It is this kind of exaggeration that clouds the issue. If the powers to be wanted to make a serious reduction in carbon dioxide they would start using more natural gas in place of coal and oil and make an immediate push for cars and trucks. Moving the transportation industry over to natural gas would have a significant effect on the carbon dioxide problem since natural gas produces about half the carbon dioxide that coal does and about 2/3rds of what oil does.
