Enviromental issues (carbon footprints) - Essay ExampleAccording to the American Meteorological beau monde (AMS, 2007), the direct human impact on the climate change is through the enhanced concentration of define gases such as carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor which, collectively, are known as the glasshouse gases. With the enhanced amounts of greenhouse gases in the earths cash machine, the infrared radiation emitted by the earth and its atmosphere is blocked by the thickening blanket of greenhouse gases, resulting to increased warmth in the earths temperature in its attempt to equalize the incoming and outgoing flows of energy.AMS (2007) further reports that Carbon dioxide (CO) accounts for about half of the human-induced greenhouse gas contribution to global warming since the latter part of 1800s. CO concentration has been increasing in general from fossil fuel burning and partly from clearing of vegetation. Significant part (50%) of the increased CO emissions ashes in the atmosphere, while the rest of the earth absorbs continually the remaining 50%. Interestingly alarming is that the atmospherical CO concentration has been increasing at a much faster rate than any new(prenominal) observed in the past several thousand years geological record.The World Wildlife Fund (WWF, 2009) reports that approximately 97 percent of the CO emitted by the western industrialized nations is mainly coming from burning coal, fossil oil and gas energy. The western industrialized nations spew into the atmosphere approximately 25 billion metric loads of CO each year, which is enough to cause temperature build-up that seriously disrupts the world climates natural balance.As the scientific community continues to understand, monitor and discover things about the environmental changes happening around the globe, it also tries to picture scientific discoveries into
