The association of the greenhouse effect with the current global warming gives it a negative connotation. The consumption of alternative energy systems like solar PV cells and wind turbines as a way to generate electricity is now increasing for that reason. Nonetheless, to sustain life on the planet, the natural occurring greenhouse effect is essential.

What is a Greenhouse Effect?

The reflection of the radiated heat from the sun further up into our atmosphere is actually a slow-moving energy called an “infrared radiation.” Greenhouse gases seen in our atmosphere capture this heat. Many of these gases are the following: water vapour, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases.

Greenhouse effect is significant in creating a perfect temperature on our planet but the creation of man-made greenhouse gases only boosts the natural process.Fortunately, some alternative energy sources are now being employed through solar panel systems, windmills, hydroelectric dams and geothermal systems.

This may serve as one of the solutions to address the global warming problem. Hopefully, this helps with the question of what causes the green house effect.

What are the Human Contributions to the Greenhouse Effect?

Burning off of fossil fuels including coal, oil and natural gas that lead to an increased carbon dioxide concentrations. The burning of rainforests and emissions of automobiles greatly cause this rise. Some of the carbon dioxide released is consumed by plants and trees for their biological processes.

Some factories emit industrial gases called fluorinated gases (hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) that are utilized in place of ozone-depleting substances such as CFCs. Its potency had given it the term High Global Warming Potential gases (“High GWP gases”). These gases are great contributing factors to the elevated greenhouse effect.

Population growth gives rise to the increased necessity for fossil fuels to be burned for heat, transportation and manufacturing of substances and devices. The application of solar PV systems greatly minimizes the necessity to utilize fossil fuels for our needs.

The increased concentrations of greenhouse gases as a result of human activities suggests there will also be an increase in the temperature of the earth. We might just be left to live in a dying planet if we dismiss these concerns.

The usage of alternative sources of energy like solar power could serve as a great progress to stop global warming. The solar panel information site is a good start in learning more about solar energy to power your homes and offices. Its content has a generous read on solar PV cells and solar panel systems fit for your needs.

When discussing the preservation of our earth, two major issues are always in the forefront: the destruction of the vital ozone layer and the question of the greenhouse effect, which may be causing the increase of temperature of the atmosphere.

Ozone is an unstable gas (rather rare). It is a toxic form of oxygen. It consists of three atoms of oxygen in one molecule, while in the common molecule of oxygen there are only two atoms. Ozone is present in the entire atmosphere up to the altitude of approximately 50 kilometres. The layer containing the highest concentration of ozone (the ozone layer) is situated in the lower geographical latitudes at approximately 25 kilometres above the point zero (sea level). The altitude of the ozone layer decreases in the direction of polar regions.

By means of photochemical reaction, the short-wave part of ultraviolet rays changes oxygen into ozone.

In this way, the majority of cell-damaging ultraviolet light is absorbed.

The use of chloro-fluoro-carbohydrates in sprays and manufacture of foams causes long-term damage of the protective ozone layer. The reason is, that when these gases are released, they rises very slowly into the atmosphere. There, they are dissolved by the ultraviolet light into free atoms of chlorine. They interact with ozone and destroy it. When the ozone layer is damaged, ultraviolet light penetrates to the surface of the earth. Chloro-fluoro-carbohydrates have a very long life and may continue destroying the ozone layer during many years.

This destructive process is specially noticeable at lower temperatures. A considerable decrease in the ozone layer was registered several years ago at the south pole during the winter season.

This decrease is called the ozone hole. More than half of the ultraviolet rays pass through the hole. The consequence of this energy-releasing process is the release of heat. In the meantime, this effect emerged also over the north pole. In Antarctica, when at the end of the polar night the atmosphere gradually warms up again, air from the lower latitudes, rich in ozone, streams in and “fills up” the ozone hole.

In autumn of the year 2000, the hole in the ozone layer over Antarctica increased to 29 million cubic kilometres, which is four times the size of Australia. According to the information of New Zealand Antarctic stations, this increases the risk of exposure to cancer-producing ultraviolet light for the population of the southern hemisphere as never before. Antarctica as such is also threatened, because its very sensitive ecosystem may be quickly destroyed by this situation.

While the ozone in the stratosphere is being depleted, in the lower layers of the atmosphere, i.e., in the troposphere, the amount of ozone is on the increase as a result of the emissions of the automobiles (nitrogen and sulfur oxides). However, this does not help balance the decreased amounts of ozone in the stratosphere.

Even assuming that there will be a complete halt in use of the chloro-fluoro-carbohydrates, it must be taken into consideration that their damaging effects will increase. In the higher latitudes, people must take precautions and protect themselves against the ultraviolet light of the sun.

In most cases, the term “greenhouse effect” is synonymous with a negative, man-made climate change. However, without a natural greenhouse effect, the life on our planet would be impossible. The earth would remain hostile to life.

Sunlight easily passes into a greenhouse and warms it up. However, the heat cannot easily escape. That way, the heat accumulates, and that is very similar to what is going on in the atmosphere that surrounds us. It is made up of different gases: 78.1 percent of nitrogen, 21 percent of oxygen, 0.9 percent of argon, 0.03 percent of carbon dioxide, and traces of noble gases.

Fifty percent of sunlight easily reach the earth’s surface, which is heated by this sunlight. The heated earth also irradiates heat. This heat, analogous to the heat of a greenhouse, cannot easily escape through the atmosphere into the universe. It is held in the atmosphere, mostly by water vapour and carbon dioxide. These two gases absorb the heat and transfer it back to the earth.

At the present time, the mean temperature on the earth is plus 15 degrees Celsius. Without the greenhouse effect, the mean temperature would also be around 15 degrees, but it would be with the other symbol, that is to say, minus 15 degrees Celsius.

In the last few decades, people have caused the increase of the greenhouse effect. Industry, transportation and agriculture, all share in the additional amounts of the greenhouse gases being produced. These gases prevent the heat to escape into the universe, and reflect it back to the earth.

The more greenhouse gases there are, the more heat stays within the earth-atmosphere cycle. Carbon dioxide is not the only gas that increases the temperature in the atmosphere. There is also methane, which is released when forests are cleared by burning. It is also released by landfills and by many ruminants, such as beef cattle, sheep and goats. Carbon dioxide is exhaled by people and animals. It also escapes from volcanoes and is released by burning of fossil fuels. The ozone of the lower layers of the atmosphere is also one of the greenhouse gases.

However, it is not absolutely clear, whether the global warming is caused by the increased production of greenhouse gases, that is to say, by man. (Today, it’s already been demonstrated – note of the editor). Without any doubt, though, the increase in global warming during the 20the century had been extreme. That century was the warmest one in the last 500 years.

The green-house effect is the most important cause behind global warming. In fact global warming is known as the greenhouse effect. This phenomenon leads to an increase in the Earth temperature due to certain gases like CO2, nitrous oxide, and methane. These gases trap the energy from the sun and without them the heat would go back into space and Earth would be one massive iceberg. Since these gases warm the Earth, they are known as greenhouse gases.

In the last couple of decades, people have started using glass houses to grow plants in winter and these are called greenhouses. Typically, these houses will trap the heat from the sun. The glasses in the greenhouse let the light through and at the same time prevent the heat from escaping.

As a result, the greenhouse heats up to keep the plants alive in the winter. Similarly, the greenhouse gases in the Earths atmosphere work like the glass and prevent the heat from escaping.

The sunlight enters piercing through the cloud of greenhouse gases and when it reaches the Earths surface, it is absorbed by land, water, and air.

After absorption the same energy is sent back into the atmosphere. Some of it remains trapped in the atmosphere due to the greenhouse gases and this energy makes the Earth warmer. Since there has been an increase in CO2 emissions in the last couple of decades, more and more heat is being absorbed in the atmosphere. This is increasing the temperature of the Earth gradually and causing global warming.

Climate Change is the abnormal change in the weather conditions which causes serious effects in human lives. It can be a change in the distribution of weather events around the world. That is over heat or over rain which is not normal. The Climate Change is largely related to the Global Warming. Global warming gets highly increased because of the serious climate changes.

The climate in the world has been changing day by day mainly due to human activities like fossil fuel burning, usage of heavy plastics, industrial wastes, e-wastes, change in the land usage and pesticides used with agricultural lands. While burning the fossil fuels for electricity and other industrial processing, excessive amount of carbon-dioxide (CO2). The liberated CO2 covers the planet as a blanket which absorbs large amount of heat and keeps the planet warm.

The second major reason is the usage of plastics and the e-wastes. Wide usage of plastics can change the conditions of the soil, which in turn leads to lot of changes in the climate. E-wastes like electrical and electronic waste products will also leads to serious climate change effects.

Physical &Social Impacts of Climate Change:

Due to climate change lot of ill effects can be caused to the human lives. The average land and sea temperature can be increases to a large extent. There is an increase in floods, droughts, wildfires, earth quakes and various other measures. As a result of global warming the glaciers gets melting which will leads to severe flooding. The ice and the snow in the north and the south poles is melting and breaking continuously.

Agriculture is highly affected by the droughts which leads to scarcity of food supply. People loss their life and property by hurricanes and floods. New diseases arriving day by day and largely spoil the human life.

The natural warming process of the earth is called as Greenhouse Effect. The heat energy reaches the earth from the sun, some of the heat energy is absorbed by the earth and the remaining reflected back to the space. This is the normal process. But by the global warming the greenhouse gases forms a blanket around the earth which does not allow the heat to the space. This excess heat makes the earth to get warm to a great extent. Some of the greenhouse gases are:

1. Carbon-dioxide (CO2)

2. Methane (CH4)

3. Nitrous Oxide (N2O)

The emissions which is generated during the combustion or decomposition of bio-materials is called as Bio-genital greenhouse gas emissions. This emission also include the sources like:

1. Utilizing forest and agricultural products for energy

2. Waste water treatment

3. Livestock management

4. Fermentation process for producing ethanol.

The carbon-dioxide is emitted to the earth by normal human processes. This cannot be avoidable but it should be controlled in a regular manner. But the flourinated gases like methane and ethanol are emitted only by the human activities like industrialization, deforestation and pollution. So it is the duty to every citizen to be aware of these effects and try to avoid such emissions.

Glass greenhouse as the name indicates is a greenhouse design made in glass to provide better growing ambience to all kinds of plants. Though with the passing of time today you get greenhouse designs in different metals, yet the traditionally the glass greenhouse has always been the preferred option.

Glass greenhouse has always been preferred since the time of yore for their universal beauty. Imagine a glass house with colorful flowers of various hues blooming inside. Nothing can be more appealing to an onlooker than this. Well, a glass house just brings color to a dull place. Put one in your house, and it’s sure to attract everyone there. Even you would love to rejuvenate yourself in this corner. You can also use any kind of greenhouse equipment with these glass houses.

Just look at any of the old conservatory design across the world and you would find green house made of glass. Every wondered why? Well, the reason is simple apart from offering you a beautiful atmosphere; it offers permanence, which is precisely the reason why it was used since the 1800 AD in England. Nowadays, you would find glass greenhouses that are controlled by computers and logic boards, which makes them still the number one choice for hobbyists, and professional plant growers.

Glass greenhouse provides the much needed environment for growing plants. This is because it has superior light transmission and super ventilation even in hot weather. It can also absorb maximum sunlight, which is ideal for all kinds of plant growth. This is especially very helpful for the plants during the winters, when it’s chilly outside. They indeed provide great greenhouse effect.

Glass greenhouse is great because of its numerous variations which can cater to all your needs. Nowadays, you can also get custom-made greenhouse installation. There are varieties like standard truss designs that permit clear-span widths in either free-standing or gutter-connected combinations.

When it comes to greenhouses, choose only glass greenhouse, and feel the difference!

Greenhouse is mainly built of glass or plastic roof material that would heat up inside. Why this is so? It is because it warms up the air inside as the sun warms up the ground.

The air remains to heat up because it is enclosed within the greenhouse not like the condition outside the greenhouse where the hot air close to the surface will come up and creates with more cooler air up above.

This can be shown by opening a small window close to the roof of a greenhouse: the degree of heat or the humidity will fall to some extent. It has also been demonstrated experimentally that a “greenhouse” with a cover of rock salt heats up an enclosure similarly to one with a glass cover.

As we all know, a greenhouse is the suppression of controlling the temperature and humidity for the cultivation and the protection of your plants or vegetables inside the greenhouse. Thus, a real greenhouse does act like a blanket to prevent bubbles of warm air from being carried away from the surface.

As we have seen, this is not how the atmosphere keeps the earth’s surface warm. Indeed, the atmosphere facilitates rather than suppresses convection.

One sometimes hears the comparison between the greenhouse effect in the atmosphere (not in real greenhouses) and the interior of a parked car which has been left in the summer sun with its windows rolled up.

This comparison is as phony as is the comparison to real greenhouses. Again, keeping the windows closed merely suppresses convection. Whether the topic is a real greenhouse or a car, one still hears the old saw that each stays warm because visible radiation (light) can pass through the windows, and infrared radiation cannot.

In fact, it has been known for a century now that the issue about this is given a little attention. Greenhouse is one step closer to Devon island. Mars on earth: the nasa Haughton-mars project.

A greenhouse is one of the best parts of greenhouse gardening for working with shade cloths, earth boxes, cold frames, and greenhouses can greatly improve your chances.

Sometimes, a greenhouse will be built against a building or by using the present construction for one or more of its sides. It is usually secured to a house, but may be attached to other buildings.

The greenhouse is limited to single or double-row plant benches with a total width of 7 to 12 feet. It can be as high as the edifice to which it is attached. The advantage of the lean-to greenhouse is that it usually is close to available electricity, water, and heat.

Greenhouse gas emissions are known to be directly related to the perceived heightened warming of the earth’s oceans and near-surface air. But how does recycling help in cutting back on greenhouse gas emissions?

Recycling is used to refer to the reprocessing of previously manufactured products (such as plastic bottles) so that their core elements (in this case, the plastic substances that make up plastic bottles) can be used to make new products later on. It should be clarified that recycling is different from re-use, because the latter simply means that the previously manufactured product (such as a plastic bottle) will be used for other purposes aside from its original use (such as when a plastic bottle is cut in half and then converted into a plant container.)

When previously manufactured products are recycled, this helps in reducing the amount of energy used to produce new products (compared to “virgin production” where products that are manufactured from substances that were taken purely from the earth’s environment – also known as raw materials.) One substance that has been quite damaging to the environment is plastic, because it does not degrade and become re-absorbed into the environment. There is also less waste that goes into disposal systems such as landfills when recycling is put into play.

When products are recycled, there is less need to look for raw materials from virgin sources. For example, aluminum is one substance which can be recycled over and over again without a decline in the quality of the substance. When plastic is recycled, up to 70% of energy is saved. If paper is the substance being recycled, up to 40% of energy is saved. When less energy is used to produce a product, that means less greenhouse gases are emitted into the atmosphere, which helps reduce the impact on the environment through the greenhouse effect.

Energy is also saved because there is less of the virgin or raw materials that has to be sought after, there is less energy needed to transport these virgin materials from their original sources, and there is less energy to be expended trying to clean up the environment when pollutants like non-biodegradable aluminum and plastic containers are dumped into landfills.

Some criticize recycling since there is still a level of energy required to transport recyclables to recycling centers and recycling plants, and in the recycling process itself. However, the energy savings derived from recycling are considerable, and much less energy will be used to make new products from recyclables compared to the use of virgin materials for manufacturing new products. Another criticism is that recycling can become impractical because the cumulative costs for recycling a certain product may outweigh the environmental benefits derived from recycling.

Despite such criticisms, it is generally accepted nowadays that recycling does help the environment by significantly reducing demands on energy supplies, so that less greenhouse gases are emitted, and can be a cost-effective solution in certain cases.

Greenhouses are usually built of glass, plastic, or a plastic-type material. It heats up mainly because the sun warms the ground inside it, which then warms the air in the greenhouse.

The air remains to heat up because it is enclosed within the greenhouse not like the condition outside the greenhouse where the hot air close to the surface will come up and creates with more cooler air up above.

This can be shown by opening a small window close to the roof of a greenhouse: the degree of heat or the humidity will fall to some extent. It has also been demonstrated experimentally that a “greenhouse” with a cover of rock salt heats up an enclosure similarly to one with a glass cover.

In layman terms, greenhouse effect is the rebound of the radiative energy (in the form of thermal energy) in all directions, in the atmosphere. In fact, this energy is redirected in all directions, but it is of utmost importance to regulate it back in the atmosphere; this is done so that balance can be brought about in humans and nature. A very important aspect of this whole process are the green house gases – water vapor (36-70%), carbon dioxide (9-26%), methane (4-9%), ozone (3-7%). These gases, also known as the atmospheric gases are basically responsible for trapping the thermal energy.

We see the greenhouse mechanism everyday – when our cars get heated up in the sun, in the nurseries with shades etc. the energy which is trapped back in these surfaces is indeed great for its respective processes; but when it comes to the atmosphere, it is a different thing altogether. Like the saying goes, excess of everything is bad, in the same way; the excess of the greenhouse gases (resulting in excessive radiative energy) is bad for the natural heath of the flora, fauna as well as Homo sapiens.

With the progress of mankind, discovery of fuel, deforestation, agricultural practices resulting in the emission of atmospheric methane, extensive use of CFC (chlorofluorocarbon) industrialization etc, carbon dioxide has only kept increasing in the atmosphere; and as compared to other gases, the increase in the level of carbon dioxide is the most alarming because it absorbs the most of the radiative energy.

Many measures have been taken worldwide to take initiatives to conserve energy and indirectly prevent global warming created by the greenhouse effect. There are alternate methods of utilizing energy such as solar energy, wind energy etc – which are of course very expensive, but a cheaper way to use them must be found as soon as possible. Another way to contribute our bit is through the ‘carbon offset‘.

Carbon offset is simply an effort to reduce the emission of carbon or other greenhouse gases so that this reduction is compensated for an atmospheric gases’ emission elsewhere. These are measured in metric tons of carbon dioxide-equivalent (CO2e). One carbon offset is equivalent to the reduction of one metric ton of carbon dioxide or the other greenhouse gases.

These are achieved by supporting the alternative or renewable energy plants or equipments. Here the support means a financial support. Due to the Corporate Social Responsibility measures growing throughout the world, Business carbon offsets have become a major way of contribution.
