1 listdose.com Top 10 Main Causes of Global Warming Global warming is one of the major problems which is not divided by the boundaries of various countries. Global warming is the hottest topic that anybody learned can relate to. But for those of you who do not understand what is Global Warming, here we are, it is the rise in the average temperature of the atmosphere of Earth (in Lehman language) and you ll be able to know its causes and effects after reading this write up. It is important to understand that the consequences of global warming are very significant. It must have not escaped or rather cannot escape our notice that devastations like tsunami, avalanches, landslides and some other significant changes like increasing average temperature across the globe and many more in-direct effects. The major cause of global warming is the developing number of industries in developing countries. But its better not to play the blame game rather join hands together and work together as one and fight against it so that we can save our planet from further damage. Recognizing the causes of global warming will be the first step for the universal cause. So here we bring to you Top Ten Causes of Global Warming 10. Greenhouse Effect Greenhouse effect is the process in which the atmosphere of the Earth trap some of the heat coming from the sun, making the Earth warm but due to burning fuels, cutting trees, the concentration of heat on Earth is increased to abnormal levels making greenhouse effect as one of the major causes of global warming. Carbon Dioxide, methane, nitrous oxide are the greenhouse gases which helps to keep the Earth warm. It is a natural phenomenon that takes place with the adequate concentrations of the greenhouse gases. But when the concentration of these gases rises, they disturb the climatic conditions, making the Earth more warm. These gases are not able to escape, which is the cause of worldwide increase in temperature. So the balance of carbon dioxide and other gases should be maintained so that it does not become the major reason of global warming. 9. Air Pollution The harmful gases emitted from the vehicles and factories and the greenhouse gases cause pollution in the air and these gases get captured in the atmosphere. The smoke, gather up in the atmosphere forming 1 of 5 1/29/14, 12:32 PM

2 clouds full of harmful gases which later on fall as acid rain which destroys the buildings and also lead to many dangerous diseases like cancer, skin burns and the death of plants. Plants provide us with the oxygen and if they die, the level of carbon dioxide will increase in the atmosphere which is a harmful gas. These gases also emit heat which increases the temperature of the Earth (following the same pattern as in the above paragraph) and causes global warming. 8. Depletion of Ozone Layer The ozone layer is the layer outside atmosphere which protects the surface of the Earth from the harmful Ultra-violet and infrared radiations causing dangerous diseases like skin cancer. Ozone layer depletion is also one of the causes of global warming; entering of harmful gases which helps in heating up the Earth but the other greenhouse gases like carbon dioxide, methane, that helps in heating up and also tears up the ozone layer making an Ozone Hole. Mostly the CFCs (chlorofluorocarbon) damages the ozone layer. So the ozone layer depletes due to these gases which allow the UV radiations to enter the Earth making the Earth more warm than normal and affects the temperature leading to global warming. It is interesting to note that Ozone Holes are created mainly on the poles which is the reason of melting glaciers, increase in the water level of the sea and of course significant rise in temperature. 7. Volcanic Eruptions Volcanic eruptions is also one of the major reason of global warming. These eruptions contain dust particles and gases like sulphur dioxide which stay in the atmosphere for years and block the sunlight from reaching the surface of the Earth making it cool. These dust particles affects the balance of the atmosphere and becomes a contributing factor of global warming. Though volcanic eruptions cannot be controlled but efforts can be made to decrease the sulphur dioxide levels. 6. Melting of the Glaciers 2 of 5 1/29/14, 12:32 PM

3 Melting of the glaciers is a natural phenomena. Large mountains of ice melt due to warmer temperature of the Earth so that new ice can accumulate. These ice mountains helps to equalize the temperature by beating up the heat. But there is excess melting of the ice due to the greenhouse gases in the atmosphere. These gases contribute to the melting of the ice at faster rate which leads to increased sea levels and eventually floods. If the temperature kept on rising then there is a chance that glaciers might disappear which will lead to flooding of earth and destruction of land resources. 5. Deforestation Plants give us oxygen which is the most important thing for our survival. They undergo a process of photosynthesis in which they give out oxygen and take carbon dioxide. Plants consume the air, sunlight and the carbon dioxide we breathe out to make food and oxygen. So if trees are cut, plants will not produce oxygen and the concentration of carbon dioxide will increase. Increase of carbon dioxide in the air is harmful for human beings and also disturbs the water cycle and hence the total imbalance of our ecosystem. So being one of the greenhouse gases it will lead to global warming. It s very much like not parking your car under a tree, the car gets excessively heated up, making it uncomfortable to sit in the vehicle. 4. Industrial Advancement More and more industries and factories are set up in this modern world to meet the needs of human beings. These big factories need large amount of fuels like coal, petroleum for power and electricity required by the machines to work. Burning of these fuels releases large amount of carbon dioxide which absorbs the harmful radiations from the sun making it warm, hence global warming. The smoke that is produced from these factories is mixed with the air, making it harmful for breathing. As written earlier developing countries are the major contributors towards this. 3 of 5 1/29/14, 12:32 PM

4 3. Use of Chemical Fertilizers The use of artificial chemicals for the crops has become one of the reason for global warming.these chemicals are very dangerous not only for Earth but also for human beings too. These fertilizers are rich in nitrogen oxide which is even more dangerous than carbon dioxide. These oxides of nitrogen destroys the ozone layer even more faster than any other greenhouse gas and hence let the harmful ultraviolet rays enter the atmosphere, making the Earth warm and leading to global warming. 2. Burning of Fossil Fuels Fossil fuels are burnt on a day-to-day basis and they contain high percentage of carbon, coal and petroleum and many other gases. So burning of these fuels releases large amount of extra carbon which has been entombed inside the Earth millions of years ago. The carbon that is emitted by burning these fuels is the extra carbon which is not a part of the cycle. So carbon dioxide being the greenhouse gas is provided in excess in the atmosphere which again leads to global warming. 1. Human Activities It has been said that human activities are primarily responsible for global warming. These activities are destroying the Earth at a faster rate. The emission of carbon dioxide from the vehicles, the burning of the fuels, cutting down of trees and forest to build buildings and malls, the dumping of trash everywhere and not recycling it, excessive use of plastics, smoke from the factories, etcetra. All these activities performed by human beings are major factors of the polluted gases in the air and the warming up of the Earth which destroys the ecological balance of the nature leading to global warming.
