ABSTRACT

Since the Industrial Revolution, man has introduced tremendous amounts of

carbon dioxide into the earth's atmosphere. While some of this CO2 is

assimilated into natural reservoirs, approximately 50% remains airborne.

This increase in CO2 concentration causes what is commonly known as the

greenhouse effect. The greenhouse effect is a result of the absorption of

infrared radiation by the surface of the earth. This absorption causes an

increase in the atmospheric temperature. Increasing the earth's temperature

in turn increases the amount of water vapor in the atmosphere. Since water

vapor is also a strong absorber of infrared radiation, a positive feedback

mechanism is created, leading to further infrared-radiation absorption. As

temperatures increase, atmospheric circulation patterns are altered which

will change local weather patterns.

These changes could have an enormous impact on agricultural production.

Attendant to a rise in the mean global temperature is a melting of small but

significant portion of the polar ice caps. This will result in a rise in sea level

which would flood coastal areas including major population centers. The

problem of the greenhouse effect might be remedied by a reduction in the

use of fossil fuel, large scale reforestation to increase the capacity of the

biotic sink, and development of alternate energy sources such as solar and

nuclear fusion. However, not much hope is held out for these remedies.
