Global and Domestic Carbon Dioxide Emissions & their Effect on Climate Change Overview The massive climate change or "global warming" scenario caused by the so called "greenhouse gases" such as carbon dioxide (CO2), methane (CH4), and chlorofluorocarbons (CFC's) that absorb electromagnetic radiation in the infrared, is not without dispute. Arguments ceased several years ago on the possibility of the trend, and now conversations revolve around the time necessary for the warming inception. In fact, without the natural greenhouse effect, if no trace gases existed in the atmosphere, the mean earth temperature would be 32°C (58°F) less [2], thus below the freezing point of water, and for life on earth. Current sophisticated computer climate change models conclude that by 2050 or before, the level of CO2 in the air will double from 18th century levels and leave a 4°C (7°F) increase on the mean earth temperature [2]. Though the temperature variation appears small, no change of this magnitude has ever been recorded in the geological time history of the planet, and when change has occurred by +/-1°C (+/-2°F) on the geologic record, the progression occurred over centuries if not millennia. We face a catastrophic global temperature increase of 1°C (2°F) per decade, without knowledge of the alterations that may occur in weather, precipitation patterns, ocean levels, and to life in general. | ||||||||||||||||||||||||
