| Bill Nye the Science Guy has a somewhat imprecise idea of how this whole climate thingy works. Carbon dioxide is NOT the culprit in whatever climate change is going on. This observation is too simplistic by far, as there is only a very small percentage of carbon dioxide free at any given moment in our atmosphere or dissolved in the surface waters of Earth. But that small percentage is responsible for maintaining ALL life on earth, as it is the source of the oxygen we breathe and the food source known as carbohydrates which is the direct result of the energy of sunlight acting upon a most wonderful process in green growing plants, photosynthesis. Primordial atmosphere of earth contained HUGE quantities of carbon dioxide, as well as ammonia, methane, and water vapor, plus some amount of sulfur compounds. Only as the earth cooled sufficiently so that water vapor could form liquid water, did the complex chemical reactions take place that would one day give rise to self-reproducing life forms. These primitive life forms did not by themselves use oxygen to maintain their existence, but when life forms that could evolve oxygen and carbohydrates from carbon dioxide and water came into being, the atmosphere of earth began to change. |
Introducing free oxygen in the atmosphere containing ammonia and methane caused the oxidation of these two compounds, resulting in free nitrogen and even more carbon dioxide, plus an increasing quantity of water as both liquid and water vapor. This highly reactive element also caused a change in the nature and distribution of the microscopic life forms, into aerobic and anaerobic microorganisms. The aerobic bacteria then continued their conversion of the content of the atmosphere, and to some degree the composition of the surface waters, slowly arriving at the approximate composition of the biosphere today. The hellish conditions that once existed on the surface of the earth had been converted to the living conditions that exist today, and the dimensions of that system greatly dwarf the feeble efforts of mankind to significantly alter it in any way, shape, form or manner. Get with the program, Bill Nye the Science Guy. Actually STUDY this science of which you so proudly boast.
