Unformatted sample text from the term paper:
"greenhouse effect" refers to the fact that certain gases that are part of the atmosphere, such as carbon dioxide, water vapor and methane, help to regular the earths temperature by
absorbing longwave radiation and then release this energy as the Earth cools during the night. If this process did not take place, the Earth would be much colder place (Pidwirny).
Only about 51 percent of the suns energy reaches the surface of the Earth (Pidwirny). While the ground radiates this energy back into the air, only a limited
amount of this energy actually makes it all the way back into space, as most of it is absorbed by the greenhouse gases listed above (Pidwirny). This absorption of energy
heats the atmosphere and the gases radiate this heat in all directions, with some of it being absorbed by the ground and reradiated, with the cycle repeating until "no more
longwave (energy) is available for absorption" (Pidwirny). In other words, the atmosphere absorbs some of the infrared heat radiation that comes from the Sun and some of this "trapped
heat is reradiated downward to warm the planets surface and the air immediately above it" (Lang). This effect reminded the first scientist to propose this idea, Jean Baptise Joseph Fourier
(1768-1830), of a "huge glass bell jar, made out of clouds and gases," which holds the "Earths heat close to the surface" (Lang). The idea of the gases in
the atmosphere working like a greenhouse is similar to this idea. A garden greenhouse is made out of glass and, because it is enclosed, it prevents the circulation of air,
allowing in sunlight, but trapping the heat within. But while the effect of gases in the atmosphere has a similar effect on the Earth, the term "greenhouse effect" is a
