Two Factors That Contribute to Global Warming - Essay Example

Two Factors That Contribute to Global Warming Global WarmingThe earth’s surface temperature has been increased around 0.750 C during the last century ending in 2005, as per the statistics collected by the scientists. It is likely to rise further 1.1 to 6.40 C during the twenty- first century. Studies showed that warming and sea level rise may continue for more than 1000 years even if we manage to stabilize the greenhouse gas levels. Increased global temperature can cause sea levels to raise, increased extreme weather intensities, changes in agricultural yields etc.

Though some natural phenomena such as solar variations and volcanoes probably had a small warming effect, scientists unanimously agreed that the major reasons are manmade only. Of course the invention of fossil fuel has revolutionized the human life. It boosted the industrialization in general and specifically the automobile sector. But nobody was aware of the influence of carbon dioxide (CO2) to the global warming or pretended like that in order to utilize the fossil fuel for the development of economy.

As per the nature’s law whatever the CO2 come out from the living things has been neutralized by the absorption of CO2 by the trees and plants. This equilibrium has been broken by the entry of fossil fuel. Its combustion liberates enormous amount of CO2 to the atmosphere which is not been countered by any other sources. Thus the CO2 percentage in atmosphere goes on increasing as far as we use fossil fuel and automobiles which is running with petrol and diesel. Greenhouse warming of the earth’s atmosphere would eventually increase the temperature of the ocean, and seawater, like most other substances, expands when heated.

That thermal expansion of the ocean might be sufficient to raise sea level by about 30 centimeters or more in the next 100 years. (Schneider, David). The overall rise of sea level by 30 centimeters will sink the cities which are below or around the sea level. Some studies showed that gulf countries like UAE, Bahrain, Kuwait etc and the Indian city Mumbai, are more volatile to such threat. Because of the increased warming the huge snow deposits on Arctic and Antarctic regions will be melted and this will cause the sea level raised.

It is already proved by scientists that the height of Everest decreases and also the Snow Mountains disappearing slowly due to global warming.Natural phenomena such as solar variations and volcanoes also contributed to the global warming. Though the activities inside the sun very difficult to study, scientists from their studies of sun spots believe that the fluctuations in solar activities cause global warming. This sun spots which are varying at different cycles, normally of 11 years time interval, can cause the atmospheric temperature fluctuations.

On the other hand volcanoes also can contribute to global warming through the toxic gases and substances emitted through them along with the enormous amount of heat energy. It is been proved bys scientists that energy can neither be created nor be destroyed. As per the principles of degradation of entropy, some part of energy is converted to heat energy in every irreversible processes which is dissipated in the atmosphere and their by causes global warming. Thus natural effects also can be considered as the contributor to global warming.

To prevent global warming each and every human have an important role to play. Automobile usage should be reduced and the smoke checkups of the vehicles should be done at regular intervals of time. Air conditioners and Refrigerators which is making use of the Chloro Fluro Carbons (CFC) should be avoided from the daily life. More and more trees and plants should be planted rather than destroying it.Sources1. Schneider, David- The Rising Seas (1997) Scientific American. March 1997, Volume 276, Number 3. pp. 112-117
