Water Vapor, Not Carbon Dioxide, Is Major Contributor to the Earth's Greenhouse Effect

Defining why carbon dioxide is not the major contributor to the earths greenhouse effect. In spite of the fact computer models used to support emission reductions required of the original Rio Treaty of 1992(1) and the Kyoto Protocol (2) resulted in warming increases that greatly exaggerated actual global warming, alarmists of today still believe the false notion that the carbon dioxide contribution to global warming is about 80% of all greenhouse gases considered. Using Departmrnt of Energy (DOE) (3a), Carbon Dioxide Information Analysis Center (CDIAC) (3b), Environmental Protection Agency (EPA) (4), and European research data, it is provable that such a statement is false. It will be shown the contribution of carbon dioxide is 72.369% only under studies where water vapor (H2O) content is equal to zero. When studies are carried out with water vapor considered an air pollutant with its correct percentage content of the atmospheric gases set to 95.000%(5a) (5b), the actual carbon dioxide (CO2) importance is reduced to a relatively small 3.618%.

Another significant finding of greenhouse gas relative importance in studies without and with water vapor included in the studies shows the total man-made greenhouse effect is reduced from 5.53% to 0.28% when studies without water vapor and with water vapor are conducted. In either case, man-made greenhouse effect is relatively small and does not justify the carbon tax being proposed by global warming alarmists.
