Carbon, in its elementary form, can be recognized as the crystalline of charcoal, graphite, and diamond. It is abundant in the earth's crust together with other chemical elements. Its association with these elements due to its property of sharing electrons -without giving-off electrons with other atoms of other elements- contribute to its innumerability in the forms of compounds of carbon. It is common in important commodities such as: gasoline, kerosene, fuel oils, lubricants, paraffin, wax, vitamins, hormones, plastics, explosives, fats, proteins, carbohydrates, perfumes, medicines, alcohols, and wood products. Due to carbon complexities, a division of chemistry called "organic chemistry" was made a separate field of study just to show the importance of carbon compounds in the existence of humans. Carbon dioxide (CO2) is a compound of carbon and is the product from the burning of fossil fuels, decaying matters, fermentations, respirations, and volcanic eruptions; all originated from the earth's crust. Man-made carbon dioxide is produced when we burnt wood, charcoal, petroleum, and other carbon compounds mined from the earth's sub-layer. Actually, it is not man-made as it exists naturally. Our only contribution is when we burned carbon compounds and disintegrating it to combine with oxygen. Thus, carbon dioxide is present when there is an increase in temperature or warming. When CO2 is released in the air or in the troposphere -where all human activities occur- it is absorbed by the plants in the process of photosynthesis in which the plant combines CO2 with water to produce carbohydrates, a necessity to sustain man's life. Carbon dioxide is constantly dissolves in water. Its presence in the troposphere together with other greenhouse gases are maintained in an equilibrium level. Any excess of these gases are naturally combined with water vapor and condensed into liquid water to form the ocean or back to the hydrosphere. Other carbon dioxide which reached the tropopause -the boundary between troposphere and stratosphere- are solidified to form a "dry ice" in the process known as "adiabatic cooling" and it cannot escape to the layer of stratosphere but fall back to earth's surface and the natural cycle is maintained to support life on earth. The belief that "most greenhouse gas take a very long time to leave the atmosphere" is not true. The atmosphere can hold only a certain amount of GHG and the excess is condensed together with water vapor and disposed back to the earth's surface. The same with U.N. IPCC estimate that "48 percent of the total anthropogenus CO2 emission remained in the atmosphere during the first five years of this century" is also not true because excess GHG is removed through water vapor from the troposphere by nature. CO2 can be removed also from the troposphere by incorporating it into a biomass and release oxygen into the atmosphere. The atmospheric lifetime of CO2 is not only few years but in a short period of time when it dissolves with water vapor and again condensed to the ocean or earth's surface. CO2 variable atmospheric lifetime such as those recovered from burning fossil fuels will take a thousand years lifetime if confined to a good container; but if allowed to mix with water vapor, it is immediately dissolved and its global warming potential will be over. Hence, carbon dioxide cannot contribute to global warming. Climate change being experienced in this century or the "Modern Climate Optimum" is a natural existence of our earth. The heat energy accumulated in the earth's core through thousands of years' energy positive forcings are now being gradually released to the earth's upper surface together with volcanic eruptions. And we are now approaching the cycle of "Medieval Solar Maximum" where the Vikings from Norway and Iceland as well as the natives of North America, are now finding settlement and planting crops in Greenland. The Southern Hemesphere is, likewise, being visited at Williams Field Skiway in Ross Ice Shelf near McMurdo Station. All these are the results of natural warming and cannot be attributed to human activities which the global warming alarmists are now advocating in the pursuit of self-aggrandizement and greed.
