Green House Effect and Global Warming Essay 1 (100 words)

Greenhouse effect is caused by various green house gases in the atmosphere. All the green house gases available in the atmosphere allow the passage of short wavelengths of visible lights of sun through the transparent medium, absorb heat and check the infrared radiations of longer wavelength to pass back to the space. In this way green house gases trap the heat from long wavelength radiations which result in increased temperature of the earth’s surface. Our earth’s surface is getting warm day by day causing climate change, weather patterns change and declining the healthy living of human beings, plants and animals.

Green House Effect and Global Warming Essay 2 (150 words)

The atmosphere of earth receives energy on daily basis from various resources including sun. However, it is a natural cycle that earth’s atmosphere absorb heat which again passes back to the space in order to maintain the natural cycle in the universe. But, nowadays, increasing level of green house gases in the environment released through many sources has disturbed the natural cycle by trapping heat from many resources and protecting them to go back to the space. So the current environment has become warmer than the earlier environment.

More than 50% of the heat available at the top of the atmosphere gets absorbed by the earth’s surface. The level of excess heat trapping is increasing with the rising concentration of carbon dioxide and other green house gases in the atmosphere. Carbon dioxide gas has strong absorption power and absorbs infrared radiations however does not allow to escape back into space and cause global warming.

Green House Effect and Global Warming Essay 3 (200 words)

Greenhouse effect is a process caused by the green house gases during which thermal radiations of the earth’s surface gets absorbed which again re-radiated to all directions instead of escaping back to the space. Re-radiation of the heat increases temperature in the lower atmosphere of the earth which elevates the average surface temperature. Green house gases make a sheet like blanket in the atmosphere which allows heat to come inside however does not allow them to go outside and increase earth’s temperature. There are many gases come under the category of green house gases but four major gases are named as water vapour, methane, carbon dioxide and ozone.

Some other gases like clouds which are considered as non-gas contributor to the greenhouse effect, but truly they absorb and emit infrared radiations and thus involves in green house effect. There are many reasons of increasing green house gases in the atmosphere however one main reason is human activities such as burning fossil fuels in various ways, clearing of forests, etc causes global warming. Incoming radiations from sun become visible lights having temperature of 6,000 K which gets absorbed by the earth’s surface and disturbs the whole ecological balance.


Green House Effect and Global Warming Essay 4 (250 words)

Greenhouse effect is the process on the earth planet caused by the gases trapping heat and energy from the various sources. Such gases are called as green house gas like CO2, methane, nitrogen oxide, CFCs, ozone, etc trap heat and warm the earth surface. Such gases hold the heat in the earth atmosphere and cause many changes in the climate and weather. Global warming causes increase in heat waves, floods, droughts, increase in sea level, melting glaciers, endangering many animals and plants species, and negatively affected the way of living of human beings.

Some major green house gases are carbon dioxide, water vapour, methane, and ozone are hugely affecting the environment. The main natural sources of increasing CO2 level are decay of animals and respiration. And other main reason of decreased utilization of CO2 is plants cutting. Plants are the main source of utilizing carbon dioxide and maintaining the level of oxygen. Plants also have ability to reduce the emitted greenhouse gases through natural cycle. Use of refrigerator produces chloro fluro carbons which is a green house gas. Major cause of global warming is carbon dioxide pollution because of increasing industrialization and transportation measures.

Green House Effect and Global Warming Essay 5 (300 words)

In the modern age of global warming where everybody is talking about weather and climate change however nobody is thinking about solving it. According to the research, it has been found that average earth temperature has been raised by 0.2 degree celsius in every decade. Temperature and global warming, both are affecting each other. Global warming has become an imminent threat to the existence of life on the earth. Many green house gases absorbs high amount of solar energy and heat on daily basis as well as warming the earth surface. Earlier, most of absorbed heat was radiated back to the space by the earth in order to maintain natural process and balance of heat and energy in the environment however this process has been stopped.

Nowadays, once heat and energy absorbed on the earth by the green house gases do not go back to the space and remains on the earth. The availability of high level of heat on the earth causes many negative effects and disturbs the ecology balance. There are many green house gases available on the earth however carbon dioxide and water vapour have more power to absorb infrared radiations of the earth and block such radiations to go back to the atmosphere. All the absorbed heat gets re-emitted to the earth’s surface and heat up the whole earth’s surface by increasing the temperature is known as green-house effect.

Increasing temperature causes both carbon dioxide and water vapour to get combined which impacts the global climate. This combined effect may increase the temperature by 30 degree Celsius in the surface temperature if the level of CO2 becomes double. The most alarming fact about the ever increasing surface temperature by 1 degree Celsius may hugely affect crop production all over the world due to warming of surface layer.

Global warming and greenhouse effect are the major environmental issues catching the attention of everyone because of the clear climate changes. Greenhouse effect is considered as the natural process however going very fast nowadays and has become very serious because of some human activities. Greenhouse effect caused by the green house gases has to do a lot with the global warming. Green house gases are human released gases through many activities like deforestation, industrialization, use of electricity in every area of work, and so many. There are some natural sources of releasing green house gases however they are in balance. Greenhouse effect is continuously altering the temperature of earth’s surface.

Such a huge alteration in the temperature causes earth to get warmer day by day which results in the global warming. There are many benefits as well as disadvantages of the greenhouse effect to the lives on earth. In the absence of it, earth may get too cold and in the presence of it, earth may get too hot. Both are the harmful to the living beings so, it is required to keep it in balance. There are many causes of the greenhouse effect. Three of them are most common and major cause of greenhouse effect which are CO2, water vapour, and methane. Water vapour is known as natural atmospheric gas however highly strong to absorb sun rays heat. 80 percent of the total natural greenhouse warming is caused by the water vapour and left 20 percent by other gasses.

Carbon dioxide gas is considered as the second biggest heat absorber on the earth which absorbs heat from sun rays. The major reason of CO2 emission is human activities affecting the level of carbon dioxide in the earth’s atmosphere. Deforestation and fossil fuels burning are the main human made reasons for CO2 emission. This continuous in carbon dioxide and other gases causes earth’s temperature to increase and make it warmer than before. Methane is more powerful than CO2 and can absorb 25 times more infrared radiations. This gas is created by the biological activities like digestive process of domestic animals, rice cultivation, leakage in domestic and industrial gas lines, etc. according to the Environmental Media Services Organization, it is found that only through the greenhouse effect the earth’s surface temperature may increase by 6 degrees by the year 2100. Global warming is affecting the whole ecological balance, sea level, corals reefs, marine life, plants, human beings, etc.

Global Warming and Greenhouse Gases

Humans are polluting our atmosphere causing the Greenhouse Effect. What’s the Greenhouse Effect? “The Greenhouse Effect can be visualized as follows: imagine that Earth has been encircled by a giant glass sphere. The heat of the sun penetrates through the glass. Some of the heat is absorbed by the Earth, and some is radiated back towards space. The radiated heat reaches the glass sphere and is prevented from dispersing any further”(Global Warming The Facts). This makes the heat bounce back towards the Earth, which heats it up tremendously.

The warming of the Earth is not a good thing. If the ice caps on the mountaintops were to melt it would raise the ocean by eight feet and many lives…show more content…

Alteration of this natural barrier of atmospheric gases can raise or lower the mean global temperature of the Earth”(Greenhouse Gas).

There are four major gases that cause the greenhouse effect. These chemicals are Chloroflourocarbons (CFC’s), Nitrous Oxide (N2O), Carbon Dioxide (CO2), and Methane (CH4). “CFC’s destroy ozone molecules by the thousands, causing a smaller amount of ozone in the ozone layer. This allows more UV rays hit the Earth’s surface, causing a slight increase of the Earth’s temperature. The more ozone molecules destroyed, the more UV rays enter the Earth’s atmosphere, making the temperature even higher”(What Is The Greenhouse Effect).

The next major gas is carbon dioxide. “Small amounts of carbon dioxide in the air helps keep heat in the Earth in the vital process of the Greenhouse Effect. As car exhausts and industries continue to shoot carbon dioxide in the air, the amount of carbon dioxide will increase. This causes more heat to be kept, increasing the Earth’s temperature”(What Is The Greenhouse Effect).

The third gas is nitrous oxide. Nitrous oxide has pretty much the same effect on the ozone as the chloroflourocarbons, but nitrous oxide only destroys about one-forth of what the chloroflourocarbons destroy.

The forth-major gas is methane. Methane also traps heat in to the atmosphere like carbon dioxide, but methane has a less harmful effect on
