Global warming - Essay ExampleThe incidence of climatical disasters is becoming to a greater extent and more frequent. Hurricanes, floods, drought etc be continuously occurring at different parts of the world. It has been Man induced changes in the purlieu has been causing changes atmosphere and the ecology, which is eventually leading to climate change and global warming. The objective of this easy is to study the causes and impacts of global warming. It has been estimated that the comely temperature of the air near earths surface has risen by 1.3 Fahrenheit(postnominal) (Venkataramanan & Smitha, 2011). However, this does not mean that every corner of the earth experiences an increase in temperature. This increase in the average temperature of earth has given way to systemic changes in the physical systems of the earth. For instance, the rise in temperature is experienced approximately in the poles. The systemic effect that this causes is that the ice melts in the poles which cause further change in the climatic patterns and ecological patterns in other parts of the globe. The warming in the poles along with change in odourise pattern would result in colder winters in continental Europe. Similarly, West Africa would receive more rains while of import Africa wont receive enough rain (Venkataramanan & Smitha, 2011). ... The most important source for this is fossil raise emissions. Whenever a fossil fuel is burnt in form of fuel as in the shield of cars, aero plane or industrial units, ascorbic acid dioxide is emitted to the atmosphere and it gets accumulated. The chart below represents the sector wise function of green crime syndicate gas emissions. Fig 1 Sector wise contribution of green house gas emission Source(Venkataraman & Smitha, 2011) The rude(a) form of reversal of this accumulation process is the vegetation which absorbs carbon dioxide as a source of energy. However, the indiscriminate human intervention with the green cover of the earth is hindering this natural process. Deforestation limits the scope of carbon emitted into the atmosphere being absorbed by plants. Thus the amount of carbon in the atmosphere keeps increasing causing the globe to be warmer. Moreover, when plants are destroyed and they decay, the carbon stored in them is released back into the atmosphere which aggregates the problem. There are natural systems which are called carbon sinks which stores carbon for thousands of years. The chain of activities as explained above results in these carbon sinks to fail. If the carbon stored in these carbon sinks are released, it may result in detrimental effects on earths various systems. It has been found that oceans which are carbon sinks are failing in their capacity to store carbon (Venkataramanan & Smitha, 2011). This is resulting in ocean water to turn acidic. This would in turn mean that ocean life will largely be affected. It is the green life deep down the ocean that helps the ocean to store carbon (Barnett, et al. 2005). Thus this act like a chain reply where in the ocean turns acidic and the plants
