Climate change, which refers to alteration in the average weather patterns, is a tangible problem and its existence and its effects can no longer be denied. Recent reports show that what us humans have done have had a major role on the earth's energy balance by changing the nature of the earth's pattern and the properties of our earth and by increasing the concentration of green-house gasses as well as the earth’s surface. The magnitude of the disturbance is so large that it has resulted in significant and extremely apparent climate changes. This can be due to a various number of reasons.
Firstly, the amounts of carbon dioxide in the air have been rapidly escalating day by day and it is also considered to be one of the most important human-influenced greenhouse gases, as Tony Blair, 2007 quoted 'We can debate this or that aspect of climate change, but the reality is that most people now accept our climate is indeed subject to change as a result of greenhouse gas emissions'.. This increase is primarily achieved by the burning of coal, oil, and natural gas or more commonly known as fossil fuels in order to produce energy that is used for heating, cooling, transportation etc. Clearing land for agriculture and ranching also contribute to carbon dioxide emissions. Deforestation has also been a substantial contribution to the global increase of greenhouse gasses. Methane is the second most important green house gasses that stems from human activities. Actually it is mainly a product of natural biological processes. However it’s yield can be increased by human activities, take for example, when there are more of rice agriculture, the increase of farm animals which results in increase decay of certain material from the digestive tracts of grazing animals which thus leads to the emission of methane gasses and finally by decaying material in landfills.
The most silent and long term effects are produced by CFC’s or otherwise more commonly...
