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.

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.…

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.…

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…

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 sun fuels the earth 's climate. The earth absorbs most of the sun 's energy called solar radiation, but some is reflected back into space. Clouds and a natural layer of atmospheric gases absorb a portion of earth 's heat and prevent it from escaping into space. This keeps our planet warm enough for life and is known as the natural "greenhouse effect". These atmospheric gases are known as greenhouse gases. The main greenhouse gases are carbon dioxide, water vapor, methane, nitrous oxide, and ozone (Environmental Protection Agency). Without the natural greenhouse effect, the earth 's average temperature would be much colder, and the planet would be uninhabitable.…

Greenhouse gases are a natural part of the Earth’s atmosphere. However, human activities including burning fossil fuels for energy, land clearing and agriculture have increased the quantity of greenhouse gases emitted into the earth atmosphere during the past century. As a result an increase in the planet’s average temperature has been recorded.…

Our atmosphere consists of many gases. Some of these gases, such as carbon dioxide and water vapor, naturally absorb long-wave radiation that is emitted from the earth's surface. Short-wave solar radiation enters the earth's atmosphere and is absorbed by the earth's surface. This radiation is then recycled and emitted as long wave terrestrial radiation. Gases such as water vapor and carbon dioxide absorb this radiation, hold it in the atmosphere, and keep the temperature of the earth warmer than it would otherwise be if there wasn't an atmosphere. This is what meteorologists refer to as the "natural greenhouse effect" (Mower).…

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.…

A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In the Solar System, the atmospheres of Venus, Mars, and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would average about 33 C° (59 F°) colder than the present average of 14 °C (57 °F).[2][3][4]…

Global Warming is an increase in the temperature of the Earth due to the use of fossil fuels and industrial processes that build up to the emission of greenhouse gasses, mostly carbon dioxide and methane (“Global Warming Threatens”). As energy from the sun strikes the surface of the earth, it turns into heat which, in turn, releases the heat as long-wave infrared radiation (Crowe). Gasses in the air, such as carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapor, trap some of this radiation as it tries to make its way back out to space (Olgesby). These gases trap in heat as do the windows of a greenhouse; therefore, they are called greenhouse gases (Elston). As an excess amount of these gasses are emitted into the Earth’s atmosphere by industries and fossil fuels, the temperature of the Earth’s atmosphere gradually increases (Oglesby). Humans escalate the amount of greenhouse gasses in the atmosphere by burning fossil fuels and by many manufacturing processes (Crowe). In the U.S., from 1990-1997, carbon dioxide emissions have increased 10.7 percent (Elston). This activity and a warming atmosphere are causing drastic…
