Global warming is an effect of Green house effect. Latter is caused by the increased concentration of the Green house gases i.e. carbon dioxide, sulphur dioxide in the atmosphere. Green house gases are emitted mainly due to fossil fuel burning and prevents Sun’s reflected heat from escaping into the environment, thereby, causing a rise in earth’s average temperature. This rise in earth’s average temperature is called Global Warming. Global Warming and Green House effect can’t be separated and both are inter linked.

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.
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.
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 6,000K which gets absorbed by the earth’s surface and disturbs the whole ecological balance.
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.
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.
