The atmospheric composition of carbon dioxide is 0.036% by volume. This is a wellknown fact. Its levels are presently 30% higher compared to preindustrial times. Carbon dioxide emitted by all natural sources is completely recycled by plants, vegetation, microorganisms and natural chemical processes on land and in water. Only about half of the carbon dioxide put out by humans is right now being recycled in this manner. The rest accumulates in the atmosphere for about 100 years. This information is provided only for the benefit of the majority of Goanetters who care about science and basic arithmetic, and have not let their ideologies cloud their elementary understanding of these subjects. These folk would realize that the above quote and the rest of the irrelevant material emanating from [EMAIL PROTECTED], and all the bridges built and sold from that email address, miserably fail to refute the following: 1. My earlier posts on global warming, and any of the factual information contained in them. 2. My post on Mount St. Helens, and any of the factual information contained in it. 2. The now well-established fact that the entity posting from [EMAIL PROTECTED] has disseminated a lot of misinformation on human involvement in global warming, on the so-called medieval warm period, and on greenhouse gas emissions from Mount St. Helens.
