Structure, Effects and Removal of Greenhouse Gases on Earth’s Atmosphere

Thesis Statement: Greenhouse gases, composed of 6 primary gases, play a huge role on Earth’s climate change, which can be prevented or removed by natural and individual techniques.

I. Greenhouse gases (GHG) are gaseous components in the atmosphere that contribute to the greenhouse effect.

II. The greenhouse gas emissions come mostly from energy use.

A. There are 6 primary greenhouse gases.

1. Water Vapor is one of the greenhouse gases.
2. Carbon Dioxide is one of the greenhouse gases.
3. Nitrous Oxide is one of the greenhouse gases.
4. Ozone is one of the greenhouse gases.
5. Methane is one of the greenhouse gases.
6. Chlorofluorocarbon is one of the greenhouse gases.

B. There are 6 principal pollutants that contribute to the formation of the greenhouse gas.

1. Carbon Monoxide is one of the principal pollutants.
2. Lead is one of the principal pollutants.
3. Nitrogen Dioxide is one of the principal pollutants.
4. Ozone is one of the principal pollutants.
5. Particulate Matter is one of the principal pollutants. 6. Sulfur Dioxide is one of the principal pollutants.

C. There are main sources of greenhouse gas due to human activities.

III. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions.

A. The Earth receives energy from the sun in the form of visible light. B. Greenhouse effect plays a huge role on the Earth’s climate change.

IV. There are several techniques in preventing or removing the greenhouse gases.

A. Greenhouse gases can be removed from the atmosphere by various processes. B. Greenhouse gases can be removed from the atmosphere by individual actions.

Greenhouse gases (GHG) are gases in the atmosphere that contribute to the "greenhouse effect". The light from the sun is allowed to pass through the Earth’s atmosphere by these gases. When the planet is stroked by that light, some of it is reflected back toward space as infrared radiation, or heat. The GHGs trap the heat, but the amount of energy sent from the sun to the Earth's surface should be the same as the amount of energy radiated back into space, so that the temperature of the planet’s surface is constant. When the composition of the greenhouse gas increases, particularly the carbon dioxide, it will lead to an extensive warming of the earth and the sea, called the global warming.

According to Nilsson (1992), greenhouse gases are gases that absorb the radiations that are trapped inside a glass house that cannot escape the medium. The general heating of the Earth’s atmosphere is caused by the infra-red radiations that absorbed, bend and vibrate the chemical bonding of the gas molecules and gained more momentum where the kinetic energy is transmitted to other gas molecules. Similarly, a blanket in the atmosphere is formed by these greenhouse gases in the process of absorbing the infrared radiations, thus making the temperature of the earth increasing.

The greenhouse gas is primarily composed of water vapor, carbon dioxide, nitrous oxide, ozone, methane and chlorofluorocarbon (CFC). These gases are the source for the global warming and climate change. Ironically, greenhouse gas is quite different than the huge heat-trapping tool for a greenhouse. Greenhouse gas is simply the warming of the Earth’s surface and cooling of the stratosphere reached by molecular absorption and radiation in the infrared spectrum. Human activities add to the stages of these naturally occurring gases, and many of those activities are benign and don't have significant effects on the...
