In the present day world, we are facing many environmental problems which are threatening our lives. In such case, Pollution, global warming etc are the major ecological threats we are facing. In this article, you are aimed to know about green house gases, its types, its causes, global warming, its impact on earth and the efforts to control global warming. Let us see in detail.
Green house gases
Green house gases (GHG) are nothing but the chemical compounds which are present on the surface of the Earth. That is, GHG are gases which are present on the Earth's atmosphere. The green house gases form a blanket like structure and cover the atmosphere along with the Ozone layer. The layer which is formed by these gases is capable of allowing the sunlight to pass through. When the sunlight strikes the Earth, some of the radiations such as Infrared rays (IR rays) etc get reflected. The IR rays are heat producing rays and they are absorbed by the green house gases on the atmosphere. Each and every life on this earth depends on these green house gases since if it does not exist, earth will get cooled and will be frozen. But if the rate of green house gases is higher earth will be warmer and it will cause many troubles to most of the living organisms.
Types of green house gases
There are two types of green house gases. They are classified as
Nature made green house gases
The gases such as Water vapor (which forms from the evaporation of water), Carbon dioxide (Comes from the respiration of living organisms), Methane (present in atmosphere) and Nitrous oxides (present in nature).
Man made green house gases
Evolve of Carbon dioxide from the burning of decayed organic matter, by the burning of fossil fuels, solid wastes, wood and wood made products etc. Another main reason for the increase in level of carbon dioxide is 'Deforestation'. Deforestation is nothing but cutting down of plants and trees. During the process of Photosynthesis, plants and trees intake carbon dioxide (production of food from sunlight). Thus carbon dioxide content was lowered. But deforestation leads to the increase in the level of carbon dioxide. In 1750, the level of carbon dioxide is 281 molecules per million molecules of air. But, at present, the rate of carbon dioxide per million molecules of air is 368 which have dramatically increased 31%.
Methane is 20 times more powerful in absorbing heat than carbon dioxide. It is produced by man during the production of coal and coal materials and the transport of coal, natural gas and oil etc. Nitrous oxide is 300 times more significant in absorbing heat than carbon dioxide. Apart from these, Chlorofluorocarbons (CFC) which are released by the refrigerators also contribute to green house gases. Recently, scientists have found a new gas called Trifluoromethyl Sulphur Penta Fluoride. The tragedy about the new gas is that the scientists can't find the source of it.
Green house gas effect
Thus the trapping of head producing energy radiations from the Sun by the green house gases present in the atmosphere which results in the rise of earth's temperature is called 'Green house gas effect'. Ultimately, green house gas effect results in 'Global warming'.
Impacts of global warming
Measures to control green house gas effect and global warming
I hope you have learnt about one of the major threats of environment. Man is thinking that God has created earth only for him and spoiling the atmosphere. We have only one place to live. The other planets are not capable of living. Please save our fragile planet by following the ways which I have written above. Let us save our one and only earth.
My appreciation to the author for bringing the importance of global warming and green house gases effect on it. Surely students are going to benefit from such type vast articles which is not only creative and eye opener too.
