Small Price for a Large

¶ … Small Price for a Large Benefit' which was published on New York Times on Twentieth February of this year by Robert Frank. The link for this article is http://www.nytimes.com/2010/02/21/business/economy/21view.html. Robert Frank says that predictions concerning climate change are extremely doubtful. The planners of a climate change meeting that was held last December in Copenhagen Danmark were unable to come up with accords to restrict global warming to three point six degrees Fahrenheit by the year two thousand nine hundred and ninety nine. Robert further adds that even a small upsurge in temperature would cause lethal destruction. In accordance with the latest approximations from the Integrated Global Systems Model at the Massachusetts Institute of Technology, the median prediction is for a rise of nine degrees Fahrenheit by the year two thousand nine hundred and nine if effectual countermeasures are lacking. That prediction though, may underestimate the escalation.

The same model suggests that there is a ten percent probability that the mean global temperature will climb by more than twelve point four degrees by the year two thousand and one hundred. It also suggests that there is a three percent possibility that global temperature will rise by more than fourteen point four degrees. If this happens, surely a disaster will occur. Scientists suggest that even the three point six-degree escalation shall imply extensive loss of human, animal and plant life. Thus it is hardly pessimistic to view the threat of inaction as terrifying. In comparison, the threat of taking action should terrify no one. Essentially, the threat is that if present approximations become pessimistic, the money used to control greenhouse gases which are responsible for the high temperatures wouldn't have been required to save the world. Nevertheless that money should have barred considerable destruction.

Scientific Explanation of Global Temperature Change

Basically, as the energy flows inside or out of the atmospheric system, temperature changes will result. The mean temperature of the atmospheric system shall stay equal only if the rate of energy increase from the sun is same as the rate of heat loss by infrared emission to external space. Moreover, the mean temperature of the planet earth shall only change once there is an inequality between the rates of energy added and energy lost. What this implies is that any substance which can alter the rates of flow of energy may cause the warming of the earth or the cooling of the world.

As far as man-made global warming is concerned, the additional carbon dioxide in the air is known to decrease the rate as which planet earth cools to the exterior space. This readily happens in nature during the greenhouse effect of the atmospheric system. The greenhouse effect is a natural process in which water vapor, clouds, carbon dioxide and methane serve as a radiative blanket. Therefore, the lower atmosphere of the earth and the surface are lagged. Consequently, the earths mean surface temperature is escalated by approximately thirty three degrees celsius. Likewise, the globe's natural greenhouse effect sustains the lower atmosphere and surface hot than if there was no any greenhouse effect. Therefore excess carbon dioxide in the atmosphere scarcely augments the greenhouse effect.
