Extract of sample "Greenhouse gasses"

Green house gases: Green house gases are those gases that release radiations into the atmosphere and have direct adverse impact on overall atmosphere. This could be in form of global warming, rising of sea levels that contribute to floods, melting of glaciers with Greenland ice cap already headed down the melting lane .Human activities are held responsible for this especially those that emit carbon dioxide directly into the atmosphere.
In 1820 a French mathematician Jean Baptiste Joseph Fourier introduced the concept of green house gases and termed them as those that trap heat from earth surface and release them into the atmosphere. The 19th century alone saw increase of 10 percent in carbon dioxide concentration in the earth’s atmosphere thanks to the burning of fossil fuels. It is being said that the Industrial revolution has contributed 40 percent to carbon dioxide and it is being estimated that if the activities continue at such pace the global temperature would rise by staggering 2 degree centigrade by 2050.
The main constituents of green house gases are carbon dioxide itself, nitrous oxide, methane, sulfur dioxide, besides these gases, deforestation is a serious threat and every tree cut gives rise to emission of more carbon dioxide into the atmosphere. Deforestation results in rise in number of floods and droughts because the trees stop the flow of floods. This climate change will hit different parts of the world in different manner and it is being believed that dry regions would get further drier and temperatures would soar in those parts of the world where as cold and wet regions would get further wet and temperatures will remain low throughout the duration of year.
The overall climate change will affect the available natural water, with rise in sea levels, the salt water would join the ranks of fresh water resources, and this can also result in increasing level of sediment. Existence of ”Dead Zone” with low concentration of oxygen would be on a more frequent display .The Overall Scenario will have direct implications on human life in form of asthmas and other respiratory illnesses associated with heat waves and different environmental conditions.
Ecology constitutes the study of overall natural system that encircles plants, animals, woodlots, lakes, and human beings themselves. Strong relationship exists between human beings and their surroundings. The mankind has a great impact on how the surroundings are today and how they will be 50 to 100 years down the lane. The Ecosystem in itself is at a great threat from this situation with plants and animals direct victims. Evidences have already been found that ecosystem has felt the impact of global warming. Several wild life animals are extinct now, water and the sea life is at equal threat from all the contamination, however Clean Water Act has been brought into act to ensure cleanliness in surface water
Counter measures must be taken against all these sources of nuisance. This could be in form of reduction of solid waste, industrial wastes, need for forestation, stopping the use of plastic bags, reducing the use of vehicles that emit large percentage of carbon dioxide, use rechargeable batteries, focus on use of alternate energy resources that are environment friendly.

Literary review: comparing the efforts in reducing greenhouse gasses of Europe and USA. How are they different, alike and which

...Comparing the Efforts in Reducing Greenhouse Gasses by Europe and USA Some world scientists believe that the die has already been cast. For this reason they argue that no matter how hard the world especially Europe and USA try to reduce greenhouse gases now, the atmosphere will continue to warm anyway. This is so because the ocean is slow to warm up. However, most scientists are optimistic and proactive encouraging the world to take measures geared towards mitigating global warming caused by greenhouse gaseous emissions. Policy-makers have also taken action-oriented strategies towards achievement of this role. This is one of the reasons that led to the establishment of...

Greenhouse Effects

...?Green House Effects A broad agreement among the scientists reveals that the climate of the earth is gradually changing and the primary cause of climate change is the increased levels of green house gases (GHGs) in the atmosphere. The term ‘Green house effect’ was first used by atmospheric scientists in early 1800s to describe the naturally occurring phenomena of the trace elements (Xe,Ar, Ne,He) (Green House Gas Emissions, 2012). What is Green-house Effect and how does it work? The sun expels continuous radiation on the surface of the earth. The ability to keep the earth warm is the key of all greenhouse gases present in the atmosphere. The GHGs work in conjunction to keep a balance of heat absorbed and reflected by the...

Greenhouse Gas

...? Unit 6 U06a1 There are certain significant aspects that impose extensive impact especially upon the environment by a greater level. With this concern, this part of the project would broadly comprise analyzing the perceptions like Greenhouse Gas, CFC, Air Pollution (Carbon Monoxide), Water Conservation and Land Pollution. The following discussion would ultimately reveal that the changes in the aforesaid aspects are quite important. Greenhouse Gas- This is generally formed due to the effect of infrared radiation. It is also formed by way of absorbing infrared radiation i.e. carbondioxide. This gas largely contributes to the occurrence of greenhouse effect in terms of generating large...

The Greenhouse Effect

...The Greenhouse Effect The greenhouse effect is a term that describes an increase of the average global temperature and is often associated with global warming which is the subject of great debate and concern worldwide. Although warnings about the human generated causes of an enhanced greenhouse effect and the subsequent catastrophic outcomes have been sounded for over 100 years, global warming has only recently become an important political matter. Most scientists worldwide accept the sufficient evidence that suggests global warming is already well underway and cannot be reversed anytime soon. They and reasonable people of all backgrounds and nationalities agree that if CO2 emissions...

Influence of Global Warming

...It is unimaginable to believe that in years to come, millions of people can be displaced from their homes as a result of rising seas. The issue of climate change as a result of global warming has become topical in many societies during the contemporary period due to the impact it is believed to cause on the welfare of people across the globe. The concept of global warming mainly derives from the understanding that excessive greenhouse gasses such as carbon dioxide in the atmosphere can cause the planet to overheat which has negative impacts on human beings. However, of growing concern is the notion that human activities such as industrialization are responsible for the emission of these...

Thomson Greenhouse

...Thomson Greenhouse Case Study One positive implication to the Thomsons obtaining additional department stores for their products is that operatingexpenses would reduce. This would be because a new greenhouse would not require huge investment in resources. The market will grow for some time yet so there is very little chance of any negative outcomes. 2) With the construction of a new greenhouse, the Thomsons will need to put new structures in place to facilitate the needs of the new greenhouse. In order to determine what structures need to be put in place or decisions that need to be made, the Thomsons should use a rate of return analysis, payback analysis, and break even...

Thomson Greenhouse

...Thomson Greenhouse Because of the small yet competitive market that the Thomsons find themselves in, there would not be much room for growth. In order to compete with its rivals, Thomson Greenhouse would have to focus on which target market to focus on, either upper class customers who are willing to pay for better quality products, or lower middle class customers who do not appreciate quality so much and want cheaper prices. 2. Thomson Greenhouse may need to restructure the organization to cope with a new greenhouse. To evaluate how a new greenhouse would impact the company as a whole, the Thomsons could use the following methods to do so: Rate of...

The Greenhouse Effect

...The Greenhouse Effect al affiliation: The Greenhouse Effect The planet earth is experiencing the warmest temperature in history.Scientists state that the earth’s temperature could increase 7.3-Fahrenheit degrees in the 21st century if humanity fails to reduce emissions from burning fossil fuels like coal and oil. The result would negatively affect the earth’s climate patterns, and thus, pose a threat to the existence of living things. Many of these effects are taking place in the world today in the form of changing weather patterns among others. Greenhouse effect is a process whereby gases such as carbon dioxide, chlorofluorocarbons, and other gaseous pollutants absorb Infra-Red radiation. However, they hinder it from escaping... absorbers...

Greenhouse gasses

...GREENHOUSE EFFECT The greenhouse effect occurs when certain gases - called greenhouse gases - accumulate in Earth’s atmosphere. They include gases like carbon dioxide (CO2), fluorinated gases, nitrous oxide (N2O), methane, and ozone. Greenhouse gases allows the sun’s light to shine on the Earth, but they trap heat reflected back up into Earth’s atmosphere. Along these lines, they act like the greenhouse glass walls. This greenhouse effect makes the Earth warm enough for life sustenance. Scientists say that without greenhouse effect, the average Earth temperature would drop from about 14˚C (57˚F) to –18˚C (–0.4˚F) (Ramseur, 2008). Some greenhouse gases originate from natural sources. Typical, evaporation adds water vapor... into the...
