The Greenhouse Effect Essay Summary Example For Students

The Greenhouse Effect Essay Summary The Greenhouse EffectThe greenhouse effect, in environmental science, is a popular term forthe effect that certain variable constituents of the Earths lower atmospherehave on surface temperatures. These gaseswater vapor (H2O), carbon dioxide(CO2), and methane (CH4)keep ground temperatures at a global average of about15 degrees C (60 degrees F). Without them the average would be below thefreezing point of H20. The gases have this effect because as incoming solarradiation strikes the surface, the surface gives off infrared radiation, or heat,that the gases trap and keep near ground level. The effect is comparable to theway in which a greenhouse traps heat, hence the term.

Even alimited rise in average surface temperature might lead to at least partialmelting of the polar ice caps and hence a major rise in sea level, along withother severe environmental agitation. An example of a runaway greenhouse effectis Earths near-twin planetary neighbor Venus. Because of Venuss thick CO2atmosphere, the planets cloud-covered surface is hot enough to melt lead. Water vapor is an important greenhouse gas. It is a major reason whyhumid regions experience less cooling at night than do dry regions. However,variations in the atmospheres CO2 content are what have played a major role inpast climatic changes. In recent decades there has been a global increase inatmospheric CO2, largely as a result of the burning of fossil fuels. If themany other determinants of the Earths present global climate remain more orless constant, the CO2 increase should raise the average temperature at theEarths surface. As the atmosphere warmed, the amount of H2O would probablyalso increase, because warm air can contain more H2O than can cooler air. Thisprocess might go on indefinitely. On the other hand, reverse processes coulddevelop such as increased cloud cover and increased absorption of CO2 byphytoplankton in the ocean. These would act as natural feedbacks, loweringtemperatures. In fact, a great deal remains unknown about the cycling of carbonthrough the environment, and in particular about the role of oceans in thisatmospheric carbon cycle. Many further uncertainties exist in greenhouse-effectstudies because the temperature records being used tend to represent the warmerurban areas rather than the global environment. Beyond that, the effects of CH4,natural trace gases, and industrial pollutantsindeed, the complex interactionsof all of these climate controls working togetherare only beginning to beunderstood by workers in the environmental sciences. Despite such uncertainties, numerous scientists have maintained that therise in global temperatures in the 1980s and early 1990s is a result of thegreenhouse effect. A report issued in 1990 by the Intergovernmental Panel onClimate Change (IPCC), prepared by 170 scientists worldwide, further warned thatthe effect could continue to increase markedly. Most major Western industrialnations have pledged to stabilize or reduce their CO2 emissions during the 1990s. The U.S. pledge thus far concerns only chlorofluorocarbons (CFCs). CFCs attackthe ozone layer and contribute thereby to the greenhouse effect, because theozone layer protects the growth of ocean phytoplankton. would probably alsoincrease, because warm air can contain more water than can cooler air. Thisprocess might go on indefinitely. On the other hand, reverse processes coulddevelop such as increased cloud cover and increased absorption of CO2 byphytoplankton in the ocean. These would act as natural feedbacks, loweringtemperatures. Science
