Rationale
The “Greenhouse Effect” is a term that refers to a physical property of the Earth's atmosphere. If the Earth had no atmosphere, its average surface temperature would be very low of about 18℃ rather than the comfortable 15℃ found today. The difference in temperature is due to a suite of gases called greenhouse gases which affect the overall energy balance of the Earth's system by absorbing infrared radiation. In its existing state, the Earth atmosphere system balances absorption of solar radiation by emission of infrared radiation to space (Climatological Information Service).
The greenhouse effect of the atmosphere has never been doubted. Most of the sun's radiation is visible light, which passes through the atmosphere largely undeterred. When the radiation strikes the earth, it warms the surface, which then radiates the heat as infrared radiation. However, atmospheric CO2, water vapor, and some other gases absorb the infrared radiation rather than allow it to pass undeterred through the atmosphere to space (Titus, J. G., et. al.).
A balance of naturally occurring gases dispersed in the atmosphere determines the Earth’s climate by trapping solar heat. This phenomenon is known as the greenhouse effect. As sunlight passes through our atmosphere, the incoming solar radiation is eradiated from the Earth’s surface as heat energy. Greenhouse gases trap some of this reradiated energy, which warms the Earth (The greenhouse effect, etc.).
Objectives
The aim of this seminar series is to help develop an emerging field at the intersection of multi-disciplinary understandings of greenhouse effect. It will also help educated participants to develop environmental awareness and integrate in applying theories and management skills for future generation.
Methodology In this seminar several research of studies were made on the internet in obtaining secondary data to be discussed. Online data gathering is selected to make a seminar report to be discussed.

First, I am going to start off how it works. The Constitutional Rights Foundation explained how the “greenhouse effect” works: “Radiation from the Sun in short wavelengths easily pass through the Earth 's atmosphere and strike the surface, which reflects much of it back as longer wavelengths” (Global Warming: What Should We Do About It?). “Instead of going back into space, the longer wavelengths are absorbed by gases in the atmosphere.” “The atmosphere reflects back to the Earth 's surface a significant amount of the trapped radiation, which becomes heat.”…

Greenhouse Effect is the trapping the heat inside the planet’s atmosphere. This occurs due to the gasses that are present in the Earth’s atmosphere. These gasses are Water vapor(H2O), Carbon dioxide (CO2), Methane (CH4) ,Nitrous oxide (N2O), Chlorofluorocarbons (CFCs). These gasses are produced by various amounts of human activities.…

In “The Greenhouse Effect”, John Houghton presents a detailed description of the Greenhouse Effect how the earth keeps warm. Houghton begins by discussing how thermal radiation emitted by the Earth’s surface is completely reliant on temperature. There is a direct relationship between how warm it is and how much radiation is emitted. In other words, the higher the temperature, the larger amount of radiation emitted. He later goes on to discuss what the greenhouse effect is by first explaining the natural greenhouse effect. Houghton describes the greenhouse effect by saying there are specific gases that absorb some of the radiation emitted by the Earth’s surface and then emit radiation back out into space. These gases act as a “radiation…

Greenhouse gases keep the Earth warm through a process called the greenhouse effect. If it were not for the greenhouse gases trapping heat in the atmosphere, the Earth would be a very cold place. Greenhouse gases are any of the atmospheric gases that contribute to the greenhouse effect by absorbing infrared radiation produced by solar warming. They include carbon dioxide…

2. Solar radiation gets absorbed by the Earth's surface when it reaches Earth. This emits infrared radiation into the land, ice and water. Greenhouse gases warm the lower atmosphere because they re-emit infrared radiation in all directions that travels back downward warming the lower atmosphere. This has led to the phenomenon as the Greenhouse Effect.…

The 'greenhouse effect' takes place when certain gases in the atmosphere of the earth trap heat. The term 'greenhouse' is used because light is allowed to reach the earth, but most of the heat generated is not allowed to escape, just as in a greenhouse. The more the greenhouse gases in the atmosphere, the more heat will be trapped within the earth's atmosphere, causing average earth temperatures to rise.…

As described above, greenhouse gases released into the atmosphere trap harmful infrared radiation from the Sun, heating up and changing the climate. This ‘trapped’ infrared radiation transforms into ultraviolet radiation which pokes holes in the atmospheric ozone layer and exposes the earth’s surface and all of its’ inhabitant species. Clearly, the greenhouse effect impacts humans significantly. If the level of greenhouse gases in the atmosphere were too low, then the earth would remain too cold to sustain life.…

Earth’s atmosphere contains mostly water vapor, carbon dioxide, and methane (natural greenhouse gases) which act to keep the lower layers of the atmosphere warmer than they otherwise would be without those gases. Greenhouse gases trap infrared radiation. The radiant heat energy that the Earth naturally emits to outer space in response to solar heating. Mankind’s burning of fossil fuels releases carbon dioxide into the atmosphere and this is believed to be enhancing the Earth’s natural greenhouse effect. As of 2008, the concentration of carbon dioxide in the atmosphere was about 40% to 45% higher than it was before the start of the industrial revolution in the 1800′s.…

The concept of global warming requires a basic understanding of the greenhouse effect. Solar radiation passes through the atmosphere and is absorbed at the Earth’s surface. This heat is lost from the earth’s surface as infrared radiation. The infrared radiation cannot escape the atmosphere as easily as the solar radiation enters. Some of it is trapped by a number of gases which act similar to the glass in a greenhouse—heat can enter but cannot exit—resulting in the Greenhouse Effect. (p. 690)…

The effects of global warming is the increase in the average temperature of Earth's, grennhouse gases, aerosol , and solar variation. The most common of average temperature on earth are temperatures increase more slowly than land temperatures because of the larger effective heat capacity of the oceans and because the ocean loses more heat by evaporation. Secondly, the effects of greenhouse is the process by which absorption and emission of infrared radiation by gases in the atmosphere warm a planet's lower atmosphere and surface. Human activity since the Industrial Revolution has increased the amount of greenhouse gases in the atmosphere, leading to increased radiative forcing from carbon oxide, methane, troposphere ozone, CFCs and nitrous oxide. The destruction of stratospheric ozone by chlorofluorocarbons is sometimes mentioned in relation to global warming. Although there are a few areas of linkage, the relationship between the two is not strong. Reduction of stratospheric ozone has a cooling influence on the entire troposphere, but a warming influence on the surface. Thirdly, an aerosol is produced by volcanoes and pollutants. These aerosols exert a cooling effect by increasing the reflection of incoming sunlight. The effects of the products of fossil fuel combustion carbon oxide and aerosols have largely offset one another in recent decades, so that net warming has been due to the increase in non carbon oxide greenhouse gases such as methane. Lastly, Variations in solar variation have been the cause of past climate changes. solar forcing affect temperatures in different ways. While both increased solar activity and increased greenhouse gases are expected to warm the troposphere, an increase in solar activity should warm the stratosphere while an increase in greenhouse gases should cool the…

The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows, but it can’t get back out. This is what the greenhouse effect does to the earth. The heat and light can get through the atmosphere, but it can’t get out. As a result, the temperature rises.…
