Green House Effect

Green House Effect [450 Words]

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 is the increase in temperature of Earth and its oceans. Greenhouse gases absorb and emit infrared radiation and trap the radiation in the atmosphere in the form of heat causing greenhouse effect by warming the temperature of Earth.t. 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.
