Present the case against the anthropogenic causes of global warming Essay

Present the case against the anthropogenic causes of world(a) warming - Essay ExampleThis phenomenon is termed as global warming. There can be many negative consequences of global warming including growing risk of gentle survival on this planet (Maslin, 2007, p.9). One impact of global warming is melting of ice in the north and south poles which includes glaciers and ice sheets over West Antarctica and Greenland. There is also the risk of rising of the sea level that will result in inundation of the low-lying areas. Many species of the hide out like penguins and paired bears are rapidly decreasing in number delinquent to the melting of ice caps. Due to increase precipitation, there has also been an increase in rain and snowfall around the world. There is also ruin of coral reefs because of warming of sea water almost one third of coral reefs have already been severely damaged (Effects of global warming, n.d.). The concept of mans impact on global warming has currently become a controversial issue because of the various difficulties faced by scientists while poring over climate change. This paper argues against the anthropogenic factors of global warming and presents the natural and scientific factors responsible for this phenomenon. Greenhouse set up Greenhouse effect is the phenomenon of increased temperature of the hide outs surface and lower level of atmosphere due to emissions of various gases. Similar to a glass house where warming enters but some of it is retained and is prevented from sacking out, the earths surface too absorbs two-thirds of the suns radiation and expels one-third of the heat. In stage to maintain balance of the solar heat the earth has to give back equal amount of heat to the atmosphere. Since the earth is colder than the sun, it reflects back heat in longer wavelengths than the suns radiation. A large damp of this thermal energy emitted by land and water bodies is absorbed by the atmosphere and also by clouds that result in rainfall and cooling of the earths surface. This entire phenomenon is known as the babys room effect (What is the greenhouse effect? 2007, p.1). The most important greenhouse gas is water vapour followed by carbon dioxide which is the second most important greenhouse gas. Some of the other greenhouse gases present in the atmosphere are methane, ozone and nitrous oxide (Montzka, et al, 2011, p.43). If there would been no greenhouse effect then the surface of the earth would have been colder than the present temperature. The estimation is that without greenhouse effect the temperature of the earths surface would have been 330 C, and the earth would not have been appropriate for living beings to survive. The concern among scientists is that human activities may increase greenhouse gases to a high level which will lead to increase in temperature by 50 C at bottom the middle of this century. However, the extent to which human life will be affected is still under feud as it is still a matter of speculation how much the temperature change will affect the median(prenominal) patterns of rainfall, drought, seasons and sea level (Schneider, 19901, p.13). The amount of thermal energy reflected back to space by the earths surface depends upon the temperature of the surface. A hot surface will radiate more thermal energy than a cold surface. The amount of radiation is also
