Global Warming

In the 19th century, scientists realized that gases in the atmosphere cause a “greenhouse effect” which affects the planet’s temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the Ice ages of the distant past. At the turn of the century, Savant Awareness calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed his idea as faulty. In 1938, G. S.

Calendar argued that the level of carbon oxide was climbing and raising global temperature, but most scientists found his arguments Implausible. It was almost by chance that a few researchers In the sass discovered that global warming truly was possible. In the early sass, C. D. Keeling measured the level of carbon dioxide In the atmosphere: It was rolling fast. Researchers began to take an Interest, struggling to understand how the level of carbon dioxide had changed In the past, and how the level was Influenced by chemical and biological forces.

They found that the gas plays a crucial role In climate change, so that the rising level could gravely affect our future. This essay covers only developments relating directly to carbon dioxide, with a separate essay for Other Greenhouse Gases. Theories are discussed in the essay on Simple Models of Climate. Carbon dioxide (CO) is a greenhouse gas. As we burn fossil fuel (coal, oil and natural gas) more and more CO is being added to the greenhouse gases in the atmosphere and the earth is getting warmer. “The Carbon Dioxide Greenhouse Effect. The Carbon Dioxide Greenhouse Effect. N. P. , n. D. Web. 14 Cot. 2012.. What impact have chlorofluorocarbons (CUFF) emissions had on global warming? Global warming and ozone depletion are two separate global problems. Global warming deals with the increasing of the earths overall temperature. On the other hand, ozone is a natural protector against the sun’s ultraviolet radiation, which is harmful to living organisms. Some gases contribute to both of these global concerns. Chlorofluorocarbons (Cuffs) are the principal cause of ozone depletion and are also potent heat-trapping gases.

Reducing atmospheric concentrations of Cuffs Is crucial in preventing continued destruction of the ozone layer, but will do little to slow the rate of global warming of the earth. Chemicals used to replace Cuffs, such as hydrochlorofiuorocarbons and hydrocephalus’s, which are now widely used In automobile and domestic alarm conditioning systems, may be an added source of global warming. They are potent heat-trapping gases, and their concentrations In the atmosphere are rising quickly. “Past Question. ” Past Question. N. P. , n. D. Web. 14 Cot. 2012..

What Impact have chlorofluorocarbons CUFF emulsions had on global warming? Cuffs are a greenhouse gas, which causes warming. But they destroy ozone, and that causes cooling. Global warming and ozone depletion are two separate global problems. Global warming deals with the increasing of the earths overall ultraviolet radiation, which is harmful to living organisms. Some gases contribute to both of these global concerns. Chlorofluorocarbons (Cuffs) are the principal cause of ozone depletion and are also potent heat-trapping gases. Reducing atmospheric concentrations of Cuffs is crucial in preventing continued the earth.

Chemicals used to replace Cuffs, such as hydro chlorofluorocarbons and hydro fluorocarbons, which are now widely used in automobile and domestic air heat-trapping gases, and their concentrations in the atmosphere are rising quickly. Seaworthy, Robert A. “CUFF Destruction of Ozone. ” CUFF Destruction of Ozone. N. P. , n. D. Web. 09 cot. 2012. How is the structure of the ozone related to global warming? The structure of the ozone is related because as greenhouse gases are sent into the air the ozone layer actually gets thicker and with a thicker barrier more heat is trapped underneath the ozone.

Because it blocks out some of the UP rays and blocking some of those rays keep some heat from coming in so, that is less heat that the greenhouse gases can absorb Ozone (03) high in the atmosphere absorbs ultraviolet radiation from the sun, hereby protecting living organisms below from this dangerous radiation. The term ‘ozone hole’ refers to recent depletion of this protective layer over Earth’s polar regions. People, plants, and animals living under the ozone hole are harmed by the solar radiation now reaching the Earth’s surface-”where it causes health problems from eye damage to skin cancer.

The ozone hole, however, is not the mechanism of global warming. Ultraviolet radiation represents less than one percent of the energy from the sun-”not enough to be the cause of the excess heat from human activities. Global warming is caused primarily from putting too much carbon into the atmosphere when coal, gas, and oil are burned to generate electricity or to run our cars. These gases spread around the planet like a blanket, capturing the solar heat that would otherwise be radiated out into space.

Both of these environmental problems do, however, have a common cause-”human activities that release gases into and alter the atmosphere. Ozone depletion occurs when chlorofluorocarbons (Cuffs)-”formerly found in aerosol spray cans and refrigerants-”are released into the atmosphere. These gases, through several chemical reactions, cause the ozone molecules to break down, reducing ozone’s ultraviolet (XIV) radiation-absorbing capacity. Because our atmosphere is one connected system, it is not surprising that ozone depletion and global warming are related in other ways.

For example, evidence suggests that climate change may contribute to thinning of the protective ozone layer. “Is There a Connection between the Ozone Hole and Global Warming? ” Cuscus. Union of Concerned Scientists, 2012. Web. 09 Cot. 2012.. Would the Earth be warming as quickly if we had not invented and used internal ambition engines for our transportation? The problem of Global Warming probably started during the Industrial Revolution, but only in the last few decades burning fossil fuels leads to increased levels of carbon dioxide in the air but the government has done very little to reduce emissions.
