The emission of infrared radiation by the atmosphere results in the warming up of the surface of a planet. This process is called the greenhouse effect. In other words, certain gases in the atmosphere trap the solar energy so that the earth experiences a considerable rise in temperature. These gases include carbon dioxide, water vapor, methane, nitrous oxide etc. and they are known as green house gases. The absence of these gases will make the heat escape back into the space which will make life on earth impossible. Green houses make use of this mechanism.
Greenhouses are used to grow plants, especially in the winter. Most green houses resemble a small glass house. Here, it is the glass panel that plays the role of the greenhouse gases. The glass panels of a greenhouse allows the entrance of solar energy in the form of heat and light, but won’t let it escape. This raises the temperature inside the glass house and provides suitable atmosphere for the growth of the plants inside.
In the case of atmosphere, our earth receives energy from the sun. Once absorbed, this energy is sent back to the atmosphere. While doing so, a major portion of the energy gets absorbed by the greenhouse gases and warms up our planet. Green house effect, if enhanced considerably too can deny existence as it would heat up the earth than usual.

Now-a-days we listen Climate Change more often than before. Climate change is a global phenomenon and the term “Climate Change” is indeed a straightforward expression for such a complex subject. In fact, climate change has more than we can comprehend from this phrase and that is why it is quite essential to go at defining climate change in today’s scenario. In the present glossary of researchers and scientists, climate modification as a term is no longer in use and effect. The reason behind this is that we have come to realize the effect of the changes we make to our environment will eventually increase the temperature in many parts of the world, but at the same time will also be decrease in temperature for few parts of the planet. This however, creates a general imbalance in the climate of the world which in turn leads us to the phrase, “Climate Change.”
While wondering the effects of the climate change, the things you know of as climate modification is actually referred to as global a global phenomenon of climate change. However, with all the details and statistics we have in hand at present, we can definitely conclude that the world is unquestionably warming with the temperatures rising like never before. Climate change is a global problem with many natural disasters started taking shape; the general awareness of this factor is really low. For the better understanding of the issues associated with the climate change, we require a simple definition for climate change in relation to the warming of the planet. And this definition needs to be the one that brings us the essence of this problem without compromising the simplicities. However, the easiest and most precise definition is that climate change is the effect greenhouse gases have on the earth’s overall climate. Greenhouse gases include carbon dioxide and methane, but are not limited to these two.
While learning more about climate change, we need to understand few important facts associated with it. The first fact is that climate change is both a natural phenomena and one catalyzed by us. For instance, greenhouse gases are a natural part of the biosphere and would exist if man did not. In fact, these gases are a vital component to the existence of life on this planet. It is due to the existence of the greenhouse gases, the temperature on planet earth does not average zero degrees! These naturally occurring gases help to keep the temperature at a desirable 59 degrees. But, the climate change, which is due to the greenhouse gases, is not indeed natural. In fact, the problem we are facing is the amount of greenhouse gases in the atmosphere. These gases act as thermal blankets for the atmosphere. The more gas in the atmosphere, the thicker the blanket and the less heat escapes from earth. In the last 80years, we have been releasing this gases into our atmosphere and thus helping them to form a blanket.

Global Warming Scientists Dispute Man-made Greenhouse Effects
In February 2007, the Intergovernmental Panel on Climate Change(IPCC) stated in their Fourth Assessment Report that human actions are “very likely” (i.e. with 90% or greater probability) the cause of global warming, indicated by an increase of 0.75 degrees in average global temperatures over the last 100 years. This statement is the result of very tough discussions on a worldwide scale between thousands of climate researchers whether human activity is the main cause of global warming. The results of this discussion were presented to the public in many publications, for instance in Martin Durkin´s documentary “The Great Global Warming Swindle”, presented in March 2007 at UK´s Channel 4. The main message of this production was that man-made global warming is “a lie” and “the biggest scam of modern times.” Martin Durkin and coworkers argue that the scientific consensus on climate change is the product of “a multibillion-dollar worldwide industry, created by fanatically anti-industrial environmentalists, supported by scientists peddling scare stories to chase funding and propped up by complicit politicians and the media”. The documentary showcases scientists, politicians, economists, writers, and others who are sceptical of the scientific consensus on anthropogenic (or man-made) global warming. Some of the scientists, opposing the main stream of greenhouse gas theories, simply argue that it has not yet been ascertained whether humans are the primary cause of global warming or if there are other natural variations responsible for this phenomenon like increased solar activity, cosmic rays or variations in natural climatic cycles. There is also a series of scientists questioning the temperature records used in the databases as temperature differences attributed to the greenhouse effect are reasonable small (fractions of a ºC). The so-called “urban heat island” effect leads to a local warming in more populated areas, showing slightly higher temperatures due to to increased heat generated by cities, rather than a global temperature rise. Anyhow, this argument was confuted by the IPPC, indicating that the effect of the urban heat island on the global temperature trend is no more than 0.05 °C (0.09 °F) degrees through 1990.
Other facts presented by the film were shown to be incorrect or misinterpreted. The film asserts for instance that records of atmospheric CO2 levels since 1940 show a continuing increase, but during this period, global temperature decreased until 1975, and has increased since then. Anyhow, it is well recognized that this cooling was driven mostly by aerosols (i.e. pollution) in the atmosphere. There is nothing contradictory about this cooling when all sources of radiation changes are considered. A second argument that easily can be invalidated is the impact of the so-called “solar variation theory” on global warming. According to the authors, solar activity (and involving cosmic rays as well as heat from the sun aiding cloud formation) is currently at an extremely high level and directly linked to changes in global temperature. The film argues that solar activity is far more influential on global warming than any other anthropogenic or natural activity on Earth. What the film does not mention is that solar activity has declined over the last 30 years - at the same time as the major spike in global temperature.
But there are some statements related to the influence of the oceanic mass and water vapour on climate change which are more difficult to confute. Water vapour makes up about 98% of the greenhouse gases by volume and provides something between 40 to 80 percent of the natural greenhouse effect. It probably has the largest impact on the planet’s temperature and climatic conditions, much larger than CO2. Water particles in the form of clouds act to reflect incoming solar heat, but the film argues that the effects of clouds cannot be accurately simulated by scientists attempting to predict future weather patterns and their effects on global warming. This argument probably is correct and it is well recognized that water vapor is responsible for the natural warming up of the surface temperature to approximately 30-35ºC. Anthropogenic greenhouse effect, according to the film’s argumentation, is only about 2% of the total “natural” greenhouse effect, which corresponds to a 0.6-0.7 ºC increase in temperature. This estimate is somewhat smaller compared to the results of much more sophisticated simulations (0.9 – 2.7ºC), but there is undoubtedly an anthropogenic effect of CO2 increasing the average surface temperature.
One example of the complexity of climatic simulations is the prediction of future storm events considering global warming effects. According to a recently published study, published online by research meteorologist Tom Knutson in the journal Nature Geoscience and resumed in the New York Times (May 18, 2008), global warming isn’t to blame for the recent jump in hurricanes in the Atlantic. The study predicts that by the end of the century the number of hurricanes in the Atlantic will fall by 18 percent. In the past, Knutson has raised concerns about the effects of climate change on storms. His new paper has the potential to heat up a simmering debate among meteorologists about current and future effects of global warming in the Atlantic. And Knutson is not alone with this view. Another group of experts, those who study hurricanes and who are more often skeptical about global warming, also say there is no link between global warming and hurricane frequency. They attribute the recent increase to a natural multi-decade cycle. According to the prediction, the number of hurricanes touching land in the US and its neighbors will drop by about 30 percent because of wind factors. However, the biggest storms, those with winds of more than 110 mph, would only decrease in frequency by 8 percent. The biggest decrease is forecasted for storms with winds between 39 and 73 mph (normal tropical storms), who would decrease by 27 percent.
It’s not all good news from Knutson’s study, however. His computer model also forecasts that “hurricanes and tropical storms will be wetter and fiercer. Rainfall within 30 miles of a hurricane should jump by 37 percent and wind strength should increase by about 2 percent”, Knutson’s study says.
There are already critical reactions on this new publication. MIT hurricane meteorologist Kerry Emanuel claims that the computer model used by Knutson is not adequate enough to look at storms and according to Kevin Trenberth, a climate scientist from the National Center for Atmospheric Research in Boulder, Colo., Knutson’s computer model is poor at assessing tropical weather and ”fail to replicate storms with any kind of fidelity.” It also does not considering well enough the intensity, duration and size of the storm events, as not only the number of hurricanes is important to evaluate.
Positive feedback comes from NOAA hurricane meteorologist Chris Landsea , who wasn’t part of this study, praised Knutson’s work as ”very consistent with what’s being said all along.” ”I think global warming is a big concern, but when it comes to hurricanes the evidence for changes is pretty darn tiny,” Landsea said.

Green House Gases and Their Effects on Our Planet
By: Jerome Exner
Placed by Oscar Lama
Green house gases, are they as big of a problem as people say? People who know little about green house gases, truly are not aware how its effecting our earth, so hopefully this information clears some of this up, and will show you how serious this problem is actually is.
For 2.5 million years, the earths climate has constantly been changing, from our ice ages to warmer years, but in the last century our climate’s temperature has been rising unusually fast, from about 1.3 to 1.5 degrees Fahrenheit. Scientists believe that it is our own human activity, thats driving the temperature up, and this process is called ” global warming”.
Dating back to the times when the industrial revolution began, factories, trains, and eventually cars, have burned fossil fuels such as oil and coal, which were and still are, releasing huge amounts of carbon dioxide, and other gas’s into our earths atmosphere. These green house gases, or trapped heat near the surface of the earth, are formed by a natural process of the sun, and this is called the ” greenhouse effect”. The green house effect, begins with the sun and the energy it radiates to the earth. The Earth and the atmosphere absorb some of this energy, and the rest is radiated back into space. Now with that being said, these naturally occurring gases, in the atmosphere trap some of this energy and reflect it back, thus, warming the earth. Scientists now believe that the green house effect is getting intensified by all the extra green house gases that humans are releasing.
Signs of global warming, include a recent pattern of very warm years. 1998 was one of the warmest years in history, with 2005, a quick runner up. Furthermore, readings taken from ice core samples, Show that green house gas’s, C02, and methane, have hit there highest levels in 420,000 years, and our sea ice is also shrinking.Our sea ice has declined 10% in the last 30 years.
As long as our nations around the globe, consume these energy’s, and increase their fuel consumption, the overall mass of green house gas’s will continue to rise. Researchers predict that our temperature will increase by 2 - 10 degrees Fahrenheit by the end of the century. What is uncertain is what rising temperatures,will mean for our planet. Some forecast rising sea levels which of coarse would mean floods, along coastal areas around the world. Weather patterns are changing also, making hurricanes more frequent, severe drought is more common in warm areas, and species which are unable to adapt to this change will face a huge drop in numbers and inevitably, extinction.

Nitric Acid - Intensifying Climate Change and Furthering Its Impact to the Environment
By Jo Alelsto
Nitric acid is one of the top chemicals in production around the world. Its primary application is in the manufacture of nitrogen-based fertilizers. It is also used in explosives, metallurgy, dyes, plastics, and pharmaceuticals. Other minor applications include water treatment, fibers and polymers manufacture, liquid-propellant for rockets, printmaking, and nuclear fuel reprocessing.
Human-influenced sources may account for as much as 40% of the total NOx released into the atmosphere. The laughing gas, nitrous oxide (N2O), is approximately accountable to 7% of the greenhouse gases. The concentration of nitrous oxide in the atmosphere has significantly increased from the pre-industrial period as compared in the last two decades.
As a waste by-product of nitric acid production, oxides of nitrogen (NOx) are very harmful to the environment and they can also aggravate the effects of climate change. Emissions from nitric acid manufacturing plants may not be as significant as those of combustion of fossil fuels but a small difference in the levels of nitrogen oxides released into the atmosphere will mean a big difference since they are very harmful greenhouse gases.
Biofuels are also contributors to nitrous oxide. Contrary to popular belief, a report from the International Council for Science (ICSU) concludes that biofuel production can aggravate global warming rather than alleviating its effects. The theory is that annual plants and crops such as corn, wheat and sugar cane take up carbon dioxide during their growth. Hence, fuels burned from them have no significant carbon dioxide emissions to the atmosphere.
The same study also supported an earlier finding which determined that nitrous oxide has a more harmful effect on the environment and the climate change phenomenon than previously believed. The ability of nitrous oxide in warming up the planet is 300 times more than carbon dioxide. It also stays longer in the atmosphere.
Nitrous oxide is a natural occurring gas in the atmosphere as a result of the nitrogen cycle but it is the rate at which its concentration increases and the factors which contribute to this increase that worries scientists and environmentalists. One of the greatest factors which most of them have seen is the anthropogenic sources such as nitric acid manufacturing plants.
Greenhouse effects cannot be ignored anymore. Climate change is upon us. The weather has become even more unpredictable than before. Studies have also identified that the main cause of this phenomenon are unchecked and negligent human practices.
As a result of industrialization, comforts have been afforded to us, such as electricity, transport, and other luxuries we now enjoy. But this comes with a price, the warming up of the planet.
Is this really worth it? Can we really afford the unpredictability of the weather today, the increase in intensity of natural disasters? The world has certainly begun to experience the effects of the accumulation of greenhouse gases in the atmosphere by the higher than normal temperatures, the melting of the polar ice caps and the rising sea levels.
We have to make a move now. A move to reduce our impacts on the environment, this especially goes to those who are in the position to make a significant change in reducing nitric acid production by-products. Owners and managers of plants and companies which use nitric acid must have proper processing and disposal strategies which are environment friendly.
But the responsibility doesn’t stop there. We must do our part as well. We are also stakeholders therefore we have to take responsibility. One thing is for sure though, we have to start today. This is because of the fact that the planet will continue to warm up for no less than 150 years due residence time of carbon dioxide, nitrous oxide and other greenhouse gases in the atmosphere. It will take a long, long time before the climate becomes stable.

How Much Green House?
By: Ken Charnly
Lately, we have all been talking about the greenhouse effect. This effect relates to the expected warming of our planet resulting from changes to the composition of our atmosphere. There is mounting evidence that our own activities, most significantly the burning of fossil fuels, are a major contributor to this effect.
The predicted consequences are quite sever, including major changes in climate which will have impact on food production, and rising sea levels which will submerge coastal and other low lying communities. Lurking in the background hauntingly are the facts we have discovered about our near neighbor, the planet Venus. Because of its dense atmospheric gases, Venus has what has been described as having a runaway greenhouse effect, giving surface temperatures of about 8000F. Now I love the warm summer weather, but that is a little too hot for me.
The usual villains in the greenhouse scenario are gases such as carbon dioxide. Carbon dioxide, which, incidentally, we all exhale, has the unusual habit of absorbing infra-red radiation. Infra-red radiation for those of you less scientifically minded is actually heat radiating away from a warm object. During the day, sunlight warms the earth and during the night the Earth cools by radiating heat into space in the form of infra-red radiation. Carbon dioxide, and to a lesser extent other gases, absorb this radiation, limiting its exit out into space, and thus limiting the natural cooling effect.
Would it be safer if we had no greenhouse effect at all? Well, no, we do not want that either. There is another member of the heat absorbing clan. This is water vapor. There is a large amount of water vapor in the atmosphere at any time, which is why we have rain. The presence of water vapor as a heart absorbing gas keeps the Earth comfortably warm. Without this warmth, the planet would freeze, and life as we know it would not be possible. We therefore do need some greenhouse effect, just not too much. Mother Nature is again telling us what we should already know; in any situation, both of the extremes are harmful.

Climate Change - The Coming Crisis
By: Jonathon Hardcastle
While many contend that there are different reasons behind the changing of our climate, few can deny that our planet is going through a period of immense changes. While some may discredit the science, global warming is one of the main hypothesis for why our planet is heating up. In this article, we’ll try to explain some of the science behind global warming so that you can understand the problem more clearly.
According to numerous scientific studies, our planet’s surface temperature has increased by about 1 degree Fahrenheit within the last century. Most of this change has occurred in the past two decades, prompting the question: are our lifestyles accelerating this global change? The evidence definitely seems to point in that direction.
Many scientists point to the emission of greenhouse gases as one of the leading reasons that we are undergoing this global change. Carbon dioxide, methane, and nitrous oxide are some of the main compounds that we are releasing more and more, causing something known as the ‘Greenhouse Effect’. This occurs due to the fact that these gases tend to trap heat, and when they are released into our upper atmosphere, they trap some of the heat energy that would normally be reflected by our earth’s natural processes.
It’s an undisputed fact that there is more greenhouse gas in our atmosphere due to humanity. Since the beginning of the industrial revolution, it is estimated that the amount of carbon dioxide in the atmosphere has increased by as much as thirty percent. While a little greenhouse gas helps to keep our planet warm, the more and more that we release, the hotter the planet is going to get. That is an important fact to consider, being that our biosphere is finely tuned to live at the temperatures at which our planet currently operates. Many forms of both plant and animal life run the risk of extinction should the temperature change be accelerated. Fossil fuels are primarily responsible for the amount of greenhouse gases that we are releasing, and to help fix the problem, we are going to need to find an alternate source of energy, and quick. Research into alternative fuels has yielded several possible options, including the use of corn in the production of ethanol, which has already had proven usage in places such as Venezuela. The most accelerated period of temperature change has occurred in the past twenty years, and it’s clearly evident that we need to address this problem while we still can.

The Important Differences Between “Climate Change” and “Global Warming”
By: James Nash
Many people in the media (and elsewhere) use the terms “climate change” and “global warming” interchangeably, as if they were the same thing. But there are differences between the meanings of the two terms.
Getting a better handle on the definitions of and differences between “global warming” and “climate change” will help us understand why the threat caused by continued warming of the planet is so serious.
Planet Earth’s current warming trend is based largely on natural warming and cooling cycles that have been happening for eons; as well as human-caused additions to greenhouse gases, which are boosting the atmosphere’s ability to trap heat in the biosphere. Minor factors like an overall increase in the sun’s solar intensity play a smaller role.
While greenhouse gases are an essential component of a livable planet - they’re what keep Earth from being a lifeless ball of ice - humans are causing greenhouse gas levels to increase so quickly that it’s causing the average global temperature to rise much faster than it would naturally. This warming is predicted to lead to a variety of negative effects, including:
1) Melting (and possible disappearance) of glaciers and mountain snow caps that feed the world’s rivers and supply a large portion of the fresh water used for drinking and irrigation.
2) A rise in sea levels due to the melting of the land-based ice sheets in Greenland and Antarctica, with many islands and coastal areas ending up more exposed to storm damage or even underwater.
3) Increasingly costly “bad weather” events such as heat waves, droughts, floods, and severe storms.
4) Lowered agricultural productivity due to less favorable weather conditions, less available irrigation water, increased heat stress to plants, and an increase in pest activity due to warmer temperatures.
5) Increases in vector-borne infectious diseases like malaria and Lyme Disease.
6) Large numbers of extinctions of higher-level species due to their inability to adapt to rapidly changing climate and habitat conditions.
The first two of these effects are mostly related to increasing average temperatures. Items 3-6 are related to heat too, but also playing a role are non-temperature factors - i.e. “climate-change factors.”
Climate change is about much more than how warm or cool our temperatures are. Whereas “global warming” refers to increasing global temperatures, “climate change” refers to regional conditions. Climate is defined by a number of factors, including:
1) Average regional temperature as well as day/night temperature patterns and seasonal temperature patterns.
2) Humidity.
3) Precipitation (average amounts and seasonal patterns).
4) Average amount of sunshine and level of cloudiness.
5) Air pressure and winds.
6) Storm events (type, average number per year, and seasonal patterns).
To a great extent, this is what we think of as “weather.” Indeed, weather patterns are predicted to change in response to global warming:
1) Some areas will become drier, some will become wetter.
2) Many areas will experience an increase in severe weather events like killer heat waves, hurricanes, flood-level rains, and hail storms.
It’s tempting to think that all of these changes to the world’s climate regions will average out over time and geography and things will be fine. In fact, colder climates like Canada may even see improved agricultural yields as their seasonal temperatures rise. But overall, humanity has made a huge investment in “things as they are now, where they are now.”

The Impact of Climate Change
By: Paul Hata
The planet was once protected with ancient forests; it has been a shelter to almost 50% of all the animals and plants confined in lands. Also, the worldwide population depends on them for survival.
The most diverse ecological units exist in these forests, and they serve essential help to our planet especially in matters regulating the climate. This is the very reason why deforestation and climate changes go hand in hand. Where deforestation is, climate alteration always follows.
Unfortunately, the forests that should be the world’s shield to the growing global warming are now under threat; almost 80% of the vast land areas all over the earth have been wiped out. Everything went by in a matter of 30 years, and the foundation is due to human doings such as destructive logging and agricultural land transformations. The fact that deforestation is the second cause to climate change should alert every human being in order to put to a stop to anything that may interrupt our normal ecosystem. If no moves would be done, further retaliation of nature would surely come to pass.
Major Carbon Storehouses
It is increasingly clear that our ancient forests play a crucial role in the regulation of world climate through carbon storage and water recycle back into the atmosphere. It is a fact that the green areas of the earth are regulators of climate, and destruction of that area means contributing to a climate change. Eighteen percent of all carbon emissions come from deforestation. Instead of the forest protecting us from disastrous effects, man made phenomenon make them our source of devastation instead.
Full grown forests are the greatest keepers of carbon dioxide. Other “keepers” include: the earth soil, the plant life, and the smallest and biggest trees. Some popular forests such that of Congo represent one of the planet’s enormous carbon sources on land, and destruction of it may cause more greenhouse gas to get trapped in the atmosphere.
The carbon is emitted from the green life through logging, burning and rotting. If these illegal activities happen frequently and continuously in all parts of the world, then the levels of carbon trapped in our environment is exceedingly augmented. Climate changes happen abruptly and changes in the world environment would slowly take place.
Deforestation and Its Effect On Climate Change
When deforestation is made, climate changes begin to progress over a period of time. The gradual modification in climate show insignificant numbers, but it affects the earth in great ways. The following are some examples of global changes after massive deforestation: temperature of global surface has increased to 1F, precipitation events happen around the world and in extreme cases, snow capped mountains have decreased in cover, sea levels have risen, and thawing of permafrost has slowly been happening over the years.
It is said that in a matter of 50 decades, the world may be in an irreversible state already. If things could be prevented now, then it is highly suggested that every human take part in preserving the world.

What do greenhouses, glasshouses, and hothouses have in common? They all refer to a facility that controls the environment where specific crops are to be planted and harvested. In countries where harsh weather and climate conditions are manifest, greenhouses have revolutionized the green industry. By use of such a facility, one is able to control certain factors such as heat, temperature, and the like; creating or extending a growing season.
The Benefits of Greenhouses
A greenhouse traps heat and saves it for future use. Being able to grow one kind of plant, say out of season flowering shrubs, regardless of the external weather conditions is the main benefit of having a greenhouse. This in turn leads to the practical benefit of making certain crops, fruits, and flowers available all year round regardless of the season and weather.
A greenhouse gives you more control over the conditions that affect your plants’ growth. It gives you the ability to predict with a certain degree of accuracy how much crop you will harvest, unless of course something goes wrong in any of the various aspects and processes involved in its operations.
Because of these benefits, an enterprising individual can actually supply out of season flowers and crops and thus gain more profits because of it. The predictable plant production of greenhouse also gives a businessman a better handle on his business economics.
Construction of the Greenhouse
The materials commonly used for greenhouses include plastic and glass. These are specially modified materials that allow heat storage. Heat can then be allocated for future use so that the greenhouse can be maintained at a specific temperature all-year-round. Moreover, these structures have little or no openings because the warm air might escape and a drop in the temperature may lead to unfavorable results.
Greenhouse Limitations
Greenhouses need to comply with certain engineering specifications; this requires special design/build skills and specialized materials. Moreover, greenhouses need a lot of maintenance. Unlike normal gardening, greenhouse conditions must be strictly controlled and monitored. There are various systems for heating, cooling, circulation irrigation, and pest control. There may be specialized equipment for seeding, transplanting and potting. A greenhouses production numbers depend largely on how well the owner or the greenhouse operator has been able to maintain it at its optimal working condition.
Greenhouse for Hobbyists
Despite the costs and efforts needed to maintain a greenhouse, there are still a number of gardening aficionados who choose to maintain such facilities. While most people put up greenhouses for business purposes, there are hobbyists who maintain greenhouses for the pleasure of starting their own plants from seeds and cuttings, or to grow loved plants that would not survive the local climate outdoors. Greenhouses also make it possible for these gardening hobbyists to attend to their plants anytime they wish to do so.
