The Greenhouse Effect Essay
While the free essays can give you inspiration for writing, they cannot be used 'as is' because they will not meet your assignment's requirements. If you are in a time crunch, then you need a custom written term paper on your subject (the greenhouse effect)
Here you can hire an independent writer/researcher to custom write you an authentic essay to your specifications that will pass any plagiarism test (e.g. Turnitin). Waste no more time!
The Greenhouse Effect
The greenhouse effect, in environmental science, is a popular term for
the effect that certain variable constituents of the Earth's lower atmosphere
have on surface temperatures. These gases--water vapor (H2O), carbon dioxide
(CO2), and methane (CH4)--keep ground temperatures at a global average of about
15 degrees C (60 degrees F). Without them the average would be below the
freezing point of H20. The gases have this effect because as incoming solar
radiation 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 the
way in which a greenhouse traps heat, hence the term.
Environmental scientists are concerned that changes in the variable
contents of the atmosphere (particularly changes caused by human activities)
could cause the Earth's surface to warm up to a dangerous degree. Even a
limited rise in average surface temperature might lead to at least partial
melting of the polar ice caps and hence a major rise in sea level, along with
other severe environmental agitation. An example of a runaway greenhouse effect
is Earth's near-twin planetary neighbor Venus. Because of Venus's thick CO2
atmosphere, the planet's cloud-covered surface is hot enough to melt lead.
Water vapor is an important "greenhouse" gas. It is a major reason why
humid regions experience less cooling at night than do dry regions. However,
variations in the atmosphere's CO2 content are what have played a major role in
past climatic changes. In recent decades there has been a global increase in
atmospheric CO2, largely as a result of the burning of fossil fuels. If the
many other determinants of the Earth's present global climate remain more or
less constant, the CO2 increase should raise the average temperature at the
Earth's surface. As...
