Essay on “Green House Effect” and “Ozone Depletion”

greenhouse effect and ozone depletion

The ozone itself is characterized by a diatomic molecule, constructed by three bonded atoms which differs from the oxygen we breathe because the gas we breathe is only two molecules. Environmental issues are not all the same. Does global warming have an impact on the stratospheric ozone layer? The greenhouse effect causes the heating of the surface of any planetary body by the presence of an atmosphere comprising of gases that absorb and emit radiation. Without them the average would be below the freezing point of water. The ozone molecules, in turn absorb ultraviolet rays between 310 to 200 nm nanometers wavelength, and thereby prevent these harmful radiations from entering the Earth's atmosphere. These gases, emitted back, cause extreme warming of the surface, which facilitates melting of the polar ice caps, and raising of sea water to dangerous levels. Global warming deals with infrared radiation Furthermore, 'global warming' is primarily concerned with radiation heading outwards in the infrared band.

Clouds form more frequently in the stratosphere at lower temperatures. The Challenge of Global Warming. Greenhouse gases absorb heat at relatively low altitudes and warm the surface--but they have the opposite effect in higher altitudes because they prevent heat from rising. In addition to this global motion, strong winter are also important to concentrating ozone at the poles. The team found that the greenhouse effect was responsible not only for heating the lower atmosphere, but also for cooling the upper atmosphere.

The Challenge of Global Warming. Many species go extinct, as the climate changes faster than they can adapt. There are some connections between the two phenomena. The Rights Holder for media is the person or group credited. Ecologists' Statement on the Consequences of Rapid Climatic Change: May 20, 1997.

They are also found in cleaning solvents for computers and in the coolants used in refrigerators and air-conditioners. Air warmed by the heat from warmed interior surfaces is retained in the building by the roof and wall; the air that is warmed near the ground is prevented from rising indefinitely and flowing away. Future climate change and associated impacts caused by global warming will vary from region to region around the globe. And how do you propose closing the loophole, where China and India agree to give away their exemption and lose the money? By 1998, increases in average global temperatures stopped. New York: Oxford University Press, 1995, 393-411. Let us take a look at some of the causes and effects of ozone layer depletion.

So as the level of carbon dioxide in the atmosphere rises, the acidification of the oceans increases. The Challenge of Global Warming. It happens when the layer has been negatively affected severely and it takes time Dobson, 2005. It is mainly found in the lower part of the , approximately 15 to 30 kilometers 9 to 18 miles above the earth. Marine phytoplankton play a fundamental role in both the food chain as well as the oceanic carbon cycle.

Carbon dioxide and water vapour in the atmosphere absorb this infrared radiation and act as a blanket, with net effect atmospheric temperature rise. It is necessary to understand its importance and work to control the depletion of this layer. The absorption of ultraviolet radiation by ozone creates a source of heat. The Montreal Protocol set an important precedent but more needs to be done. Biotic Feedbacks in the Global Climate System: Will the Warming Feed the Warming? The free oxygen atom O , then combines with an oxygen molecule O 2 , and forms a molecule of ozone O 3.

Second Assessment Synthesis of Scientific-Technical Information Relevant to Interpreting Article 2 of the United Nations Framework Convention on Climate Change. When the sun comes out again in the polar spring, the ice particles melt, releasing the ozone-depleting molecules from the ice particle surfaces. Science, however, is not done by popular vote. Houghton, Gylvan Meira Filho, Robert T. In contrast, climate change is a product of greenhouse gases such as carbon dioxide. Ozone depletion is greatest in polar regions during the winter, explaining why the greatest warming observed from 1970 to 1998 was of minimum temperatures in polar regions, a phenomenon known as.

This eventually disturbs and affects the entire ecosystem. Greenhouse gases absorb this infrared radiation and convey this absorbed heat to other atmospheric gases by way of molecular collisions. While the buildup of greenhouse gases leads to global warming at Earth's surface, it also cools the stratosphere, which increases the amount of ozone depletion in the polar regions. Ultraviolet rays can influence the survival rates of these microscopic organisms, by affecting their orientation and mobility. Ultraviolet-B radiation has 48 times the frequency of infrared radiation absorbed most strongly by carbon dioxide, 48 times the energy—has the potential to make the temperature of the absorbing body 48 times hotter. The ozone gas in the atmosphere protects mankind from harmful radiation, while the greenhouse gases like carbon dioxide trap heat in the atmosphere thereby raising temperatures worldwide with harmful repercussions for the rest of the world.
