The greenhouse effect entails conditions that allow short wavelengths from sunlight to be absorbed through transparent media. However, these media cannot permit the passage of long wavelengths that are re-radiated from animated substances. Therefore, high temperatures that occur due to overheating are usually experienced.

This arises because the long wavelengths are tapped and thus causing variations in the atmosphere. It is a major issue in the world today since climatic changes cause precipitation and global warming. The accumulations of anthropogenic supporters and induced greenhouse gases encourage temperature variations. However, the greenhouse gases are transparent to the inflowing solar radiations.

These gases include CFCs (chlorofluorocarbons), O3 (troposphere ozone), N2O (nitrous oxide), CH4 (methane), CO2 (carbon dioxide), and water vapor. The gases attract and change the inward radiations to long wavelength. Hence, they cause thermal energy.

Besides, some activities carried out by man tend to increase the amount of gases retained in the atmosphere. This causes the greenhouse effect (Emanuel 2320). This study investigates the greenhouse effect. It also looks at the increase in trace-gases concentration, and the global feedbacks of greenhouse.

Views on the greenhouse effect

A greenhouse is a phrase that scientists originally used in the fiscal 1980s. It was used to explain the purpose of trace-gases that naturally occurred. This hardly imposed pessimistic implications on the atmosphere. However, the atmospheric scientists saw that the greenhouse effect was attached to most climatic change anxieties.

Recently, negative expressions have taken center stage as to what constitutes the greenhouse effect (Lindzen 8339). These concerns are connected to the probable impact of the greenhouse effects. Therefore, research shows that life would not have been possible without the greenhouse effects. In fact, the temperature of the earth is dependent on the atmospheric actions of the greenhouse effects.

Several factors affect greenhouses. This is because of its effects in cooling and heating the atmosphere. An essential facet of the atmospheric orangery is the nature of plane that is initially hit by rays. The surfaces such as cities, deserts, ice caps, ocean surfaces, grasslands, and forests, tend to absorb, reflect, and emit radiations in different ways.

A white glacier tends to reflect back sunlight that is falling on its surface. This leads to low atmospheric conditions that accrue from some amount of heat. In contrast, dark desert soils have the capacity to absorb sunlight (Arrhenius 239). This contributes to the maximum heating of surfaces and lowers the atmospheric temperature.

Moreover, the cloud coverage affects the greenhouse warming. It decreases the quantity of solar radiation that is getting into the ground. It also minimizes the degree of energy and waves that are discharged into the atmosphere. Thus, scientists have characterized a fraction of astrophysical vigor that is reproduced by such reflective planes (Reiter 54). This has helped scholars and other people to comprehend the global, regional, and local percentages. The greenhouse effect has therefore helped in the prediction of climatic changes around the world.

The greenhouse effect and increase in trace-gases concentration

Temperatures of surfaces and those of the atmosphere respond quickly to variations in the absorption of greenhouse gases. Increase in the concentration of clouds or greenhouse gases above the normal levels results into variations in altitude (Lindzen 8340). For instance, improved methane concentrations will move the altitude upwards. As a result, the temperature of the upper troposphere will change by half due to increase in surface temperature. This is apparent in a humid surface and its deviation from the altitude.

Changes in the concentration will help in calculating the surface and atmospheric temperature changes. For example, double concentration of carbon dioxide increases the world average surface temperature by one degree centigrade. Furthermore, climate systems and mechanisms affect atmospheric greenhouse gas concentration.

Plants depend on carbon dioxide for photosynthesis. Hence, they reduce the concentration of gases in the atmosphere (Emanuel 2325). The conservatory absorption in the environment is amplified by individuals’ actions. This is seen in industrial actions that lead to the clearance of forests and smoldering of fossil fuels. Introducing further greenhouse gas in the atmosphere strengthens the greenhouse effect.

Greenhouse effect feedbacks

Several feedback mechanisms depict the rate at which the globe is warming. Atmospheric warming accrues due the increment in the level of greenhouse gases. The water vapor that is found in the atmosphere also increases. This in turn increases the greenhouse effect. Therefore, excessive global warming is experienced.

From such an experience, the vapor found within the reinforcing self-cycle also causes further increment in the greenhouse effect. Due to additional carbon dioxide in the atmosphere, the greenhouse effect can be doubled. Furthermore, clouds constitute an important feedback mechanism. The absorption of infrared radiation by clouds has an impact on the greenhouse that eventually causes global warming (Arrhenius 239).

Clouds furthermore echo the received planetary rays to generate the chilly upshots on the crusts’ plane. Therefore, the extent at which clouds cool or warm the earth depends on the changes in clouds, life span, shape, particle size, altitude, water content, position and nature (Schneider 1). Some changes restrain the global warming while others intensify it. Researches on the feedback mechanisms as regards to global warming are still on track.


It can be concluded that greenhouse gases work by absorbing the infrared radiation. Hence, some energy is radiated back towards the earth surface. This surface also receives radiation from the clouds and the atmosphere. Studies show that clouds and water vapor are the most important greenhouse components in the atmosphere.

Nevertheless, water vapor quickly cycles through space, and its concentration is observed as feedback. The ozone, nitrous oxides, methane, carbon dioxide, and clouds are also important elements in the greenhouse. They increase the global warming and its absorption of various gases provided there are excessive concentrations.
