The Greenhouse Effect Essay - 830 Words
Much like the glass of a greenhouse, gases in our atmosphere sustain life on Earth by trapping the sun s heat. The Earthââ¬â¢s atmosphere contains several different gases that act like a blanket, keeping the Earth warm. Water vapour and some trace gases like CO2, CH4 (methane), O3 (ozone), N2O (nitrous oxide), are ââ¬Å"IR activeâ⬠, i.e. they absorb heat energy, and stop the warmth from escaping into space. Without the entrapment of heat, the earthââ¬â¢s mean temperature would be -180 C and life, as we know it today, would not be possible. These gases are present in the atmosphere in tiny quantities compared to the amounts of oxygen and nitrogen. But even a small change in the concentration of these gases may create an effect that could change ourâ⬠¦show more contentâ⬠¦Any factor that alters the amount of radiation received from the sun or heat lost to space may influence the climate. Therefore, any enhancement of the Greenhouse effect is a cause for concern. Besi des fluctuations of solar radiation due to the earth orbiting around the sun, human activities influence the number of greenhouse gases. In fact, since the beginning of the industrial revolution, human activities such as the burning of fossil fuels, deforestation and agriculture have caused the concentrations of greenhouse gases in the atmosphere to increase substantially. A marked rise in the global temperature has been related to these human activities and CO2 emissions, and this temperature rise is believed to be the result of an enhancement of the natural Greenhouse effect. And as a result, global warming arises.This awareness has led many researchers to investigate possible causes and effects of this temperature rise. However, as much knowledge about the climate system is lacking, numerous researches on that issue have led to a great deal of debate. At the moment, the way the climate system will respond to these human activities is difficult to predict, for too many processes a re not understood well enough. One absolute reality though is the fact that the global climate system will respond to increasing temperatures. Moreover, this response could have irreversible consequences for the habitabilityShow MoreRelated Global Warming and the Greenhouse Effect Essay591 Words à |à 3 PagesGlobal Warming and the Greenhouse Effect The greenhouse effect, in environmental science, is a popular term for the effect that certain variable constituents of the Earths lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the greenhouse effect.). The 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). WithoutRead MoreEssay on Global Warming and the Greenhouse Effect 1500 Words à |à 6 Pages Global Warming is due to the greenhouse effect. The greenhouse effect is a naturally occurring process that aids in heating the Earths surface and atmosphere. It results from the fact that certain atmospheric gases, such as carbon dioxide, water vapor, and methane, are able to change the energy balance of the planet by being able to absorb longwave radiation from the Earths surface. Without the greenhouse effect, life on this planet would probably not exist as the averageRead MoreGlobal Warming and the Greenhouse Effect Essays793 Words à |à 4 Pages What is the greenhouse effect? It is the behavior of solar radiation when it interacts with gasses in the Earths atmosphere. The Sun gives off a wide spectrum of energy which we classify according to its wavelength. Among the types of energy given off by the sun are ultraviolet (UV), visible and infrared (IR) wavelengths. UV is short wavelength high-energy radiation, visible is mid-wavelength, mid-energy radiation, and IR is long wavelength low-energy radiation.

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 processRead MoreEssay on The Greenhouse Effect and Global Warming1837 Words à |à 8 PagesThe greenhouse effect is an important phenomenon and is currently holding national and international attention. Why is there an interest in the effect? Why are people willing to invest so much time and effort investigating its consequences and willing to suffer by them? What is the basis for believing the effect is real? The greenhouse effect is a naturally occurring process, which is initiated by the sun. It is a result of the fact that there are gases in the Earthââ¬â¢s atmosphere which containRead More Global Warming and the Greenhouse Effect Essay example763 Words à |à 4 PagesGlobal Warming and the Greenhouse Effect Human induced climate change resulting from an enhanced greenhouse effect is probably the greatest environmental threat facing the world today. Specifically, the emission of greenhouse gases such as carbon dioxide may be classified as the primary culprit. As a result of greenhouse gases entering the upper levels of the earths atmosphere, it diminishes or breaks down the earths Ozone layer. With this loss of this protective blanket, harmful radioactiveRead More Global Warming and the Greenhouse Effect Essay examples457 Words à |à 2 PagesWarming and the Greenhouse Effect In the past decade the greenhouse effect has gained much attention with the media. Because of the pollution in the 1980s and early 90s attention was brought to the greenhouse effect. In overpopulated areas, the amounts of methane and carbon dioxide was growing. Some scientists believe the greenhouse effect is directly related to the earths warming, others believe its a cycle of earths temperatures. The greenhouse effect is very importantRead MoreGlobal Warming: The Greenhouse Effect and Our Response Essay example501 Words à |à 3 PagesGlobal warming (the greenhouse effect) is the increase in the temperature of Earths weather which has become popular to many people as one of the most important danger in the universe. Discussions about causes, solutions, postive and negative effects have made by human-beings. One of the first subject people learned is that there are several causes of global warming. However, one of the most effective reason is Carbondioxide gas which most come from the combustion of fossil fuels and forestsRead MoreWhat Role Has Human Activity Played in Causing Climate Change?678 Words à |à 3 Pagestemperature, ocean level, land, and precipitation. The climate change phenomenon can affect everything in the world not only natural environment, but also human society, and the world economy. This essay aims to evaluate the role of human actions that have caused the climate change. The first part of this essay will talk about the possible causes of climate change, and the second part will discuss the role of human activity, which is cause the climate change. The factors that can cause the climateRead MoreEssay on Human Activity in Climate Change721 Words à |à 3 PagesThis essay and its contents is designed to define and discuss the concept of my position on the following statement: ââ¬Å"Human activity, especially the burning of fossil fuels. It also answers inquiries of; is it a major contributor to climate change? Do I agree or disagree? From my research and readings, Iââ¬Ëve concluded that, the foremost effect that burning fossil fuels has on our environment is the greenhouse effect, also known as global warming. Carbon dioxide, which is also known as greenhouse
