The Greenhouse Effect and Global Warming Recently, global warming has moved to a serious scientific issue. Because sunlight is constantly falling on the earth, the law of physics say that the planet has to radiate the same amount of energy back into space. Infrared radiation is sent out by the earth through the atmosphere, where molecules (carbon dioxide) hold outgoing radiation for a while, warming the surface.1 The molecules are kind of like glass in a greenhouse which is why this process of warming is called the greenhouse effect. The greenhouse effect has been operating since the beginning of time. Without the effect, the surface of the earth would be -20 degrees Celsius, oceans would have frozen, and there would be no …show more content…
A decreased day and night temperature and night warming may happen when an increase of atmospheric greenhouse gases takes place. Emissions are a major problem contributing to the greenhouse effect. These gases are called volatile organic compounds (VOC’s) and consist mostly of carbon, hydrogen, oxygen, and nitrogen. These gases react in sunlight with nitrogen oxides to form photochemical smog. A lab experiment was done to simulate typical outside conditions. Stems of fescue grass and white clover were cut and tested for VOC content and researchers found that emissions of certain VOC’s spiked immediately after cutting, while others continued at a high rate for the next two days. Uncut grass also gives off VOC’s and cutting grass makes it worse. In a city like Los Angeles, mowing accounts for 10% of the VOC’s in the atmosphere, say researchers. President Bill Clinton and Vice President Al Gore have different stands on the global warming issue. Al Gore is pushing for a radical stand and wants to cut back on emissions to ten percent below the levels of 1990 and this would require a 20% cut in the fossil fuel usage. Al Gore even called for a White House conference with weather forecasters saying that the U.S. should fund more abortions in order to cut down on the number of people populating our world. Gore believes that Americans will be thankful in the long run for him saving the world from ecological
