Global Warming And The Greenhouse Effect - 1588 Words

Global warming is the increase in the average surface temperature of the Earth due to the effect of the buildup of greenhouse gases, due to deforestation and burning fossil fuels which causes the heat to be trapped that would otherwise escape from the earth. To understand global warming, you need to understand the greenhouse effect. The greenhouse effect is actually essential for life on earth to exist as it allows the planet to remain warm enough to sustain life. For example if we consider for moment a simplistic comparison of a car parked in the sun. The rays of the sun enter the car through the windows and some of the heat is absorbed by items inside the car (seats, dashboard etc). These objects will in turn begin to release heat and some of this heat escapes back through the windows but some of the heat is reflected back into the car. The result is that more heat enters the car than is able to escape it and the interior of the car warms up. So if you think of the earth’s atmosphere as the car’s interior. The landscape and structures on earth can be seen as the cars seats and dashboard. The role of the cars windows is played by certain things within the earth’s atmosphere such as carbon dioxide, methane gas and water vapour which absorb the heat reflected by the earth below. These are known as greenhouse gasses. When there are more greenhouse gasses present in the atmosphere, more heat can be retained leading to a rise in the temperature of our planet.

The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earthRead MoreGlobal Warming and the Greenhouse Effect1974 Words   |  8 PagesThe 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 processRead MoreThe Effects Of Global Warming On The Greenhouse Effect1917 Words   |  8 PagesThe Greenhouse Effect The greenhouse effect is the result of the interaction of the atmosphere of a world and the radiation emitted from the Sun and planet. This process essentially makes a world warmer that it would be. As we will learn in this chapter there are many factors that determine the strength of a world’s greenhouse effect including a world’s size, the world’s distance from the Sun and the strength of a world’s magnetic field. Before you can learn about the factors that influence the greenhouseRead MoreGlobal Warming and the Greenhouse Effect Essays793 Words   |  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.

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 MoreEssay on Global Warming and the Greenhouse Effect1912 Words   |  8 PagesGlobal Warming and the Greenhouse Effect   Ã‚  Ã‚  Ã‚  Ã‚  Recently, global warming has moved to a serious scientific issue.

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).

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.

How do greenhouse gases in the atmosphere affect global warming? Many of the greenhouse gases in the troposphere are naturally produced, which is why the Earth is able to stay at a constant average global temperature. Carbon dioxide is the main greenhouse gas in which is affecting global warming, not because of naturally produced carbon dioxide, but mainly because of manRead MoreGlobal Warming And The Human Expansion Of The Greenhouse Effect998 Words   |  4 Pagesrevolves around global warming and the human expansion of the greenhouse effect, as pictured below. Ordinarily, the sun’s radiation passes through the atmosphere, is absorbed by the Earth and then is re-radiated back into space as infra-red waves. However, due to human activities, the concentrations of greenhouse gases increase meaning that more of the heat radiating away from the Earth’s surface is trapped in the atmosphere and is re-emitted back to the Earth’s surface, thus further warming the planet
