Global Warming
Global warming means average rise in the temperature of the universe. Global warming becomes a huge problem for earth and it happens when greenhouse gases (carbon dioxide, water vapour, nitrous oxide and methane) directly comes from sun light is known as the greenhouse effect. Certain gases in the atmosphere act like glass in a green house allowing sunlight through to heat the earth’s surface but trapping the heat as it radiates back into space the atmosphere on earth gets hotter.
Carbon dioxide (C
) is the main element of the greenhouse gases. If deforestation and burning of woods increases day by day Carbon dioxide (C
) will increase rapidly, which makes ozone layer thinner and this is just because of ignorance of authorities to stop people from more deforestation. Carbon dioxide (C
) comes from burning of coal and oil.
Fossil fuels are also the main cause of rise in temperature of the Universe. Fossil fuels burned in cars, power stations and factories of the developed countries such as USA, west Europe countries and other countries.
Electricity is also produced by the burning of fossil fuels at generating stations. Fuels we use in automobiles or vehicles are producing Carbon dioxides (C
) and carbon monoxides (CO). SO we must keep them tune on time and there is a gas chloro fluro carbon (CF
) used in our house hold things like Fridges, Air Conditions and atomizers or sprays are extremely effective greenhouse gases. Although they are lower concentration of chloro fluro carbon (CF
) in the atmosphere than Carbon dioxide (C
) they trap more heat, so we must ban completely on these products.
If no action is to be taken the greenhouse effect would leads you to a rise in average global temperature than summer. Global warming increased temperature due to which storms and hurricanes will becomes more frequent and stronger. Due to more evaporation evidence in conditions for shores at sea levels.
Sea level are already at a rate of 1 to 3 cm each year due to expansion of the top layer of the Glaciers as they warm and the melting of the polar ice caps. This increase in sea level cause flooding in coastal areas and river areas such as Bangladesh and Nile delta, London and many other British coastal cities will be threatened also due to the rain-fall patterns. Some roads were damaged and this rainfall patterns increases with the increase of temperature and every thing is just because of the global warming. There is a discontinuous falling rain system that destroys our crops and vegetation. If there is a more rise in temperature more vaporization occurs and that makes clouds for rain and every thing causes the increase in sea level.
It is very important for our lives that we must save our land and to slow the warming as much as possible. All these means to use less fossil fuels eliminating (CF
) altogether and slowing down deforestation. This can be achieved by the use of energy conservation (preservation) we must stop deforestation and start replanting trees to soak up carbon dioxides.
United Nations and our governments must take some serious steps to prevent universe other wise few of countries will be disappeared. The developing countries are reluctant to participate in any greenhouse gases (C
,Co etc ) Emission reduction plans although they arguing that they did not create global warming and saying that the developed and oil producing countries are responsible for this disaster.
In this case the international treaties make some strict rules so that every one should fallow that rules and Government should take some agreements to stop global warming to save other countries.
Governments should raise the gas prices and taxes for those who use more gas so that the people will be discouraged for over use of gas. It is necessary for everyone to find an effective means of safely disposing of the radioactive wastage. We must devote ourselves for research and development of alternative pollution free energy sources such as solar waves and wind energy.
