Complete 8 page APA formatted essay: Global Warming: Predicted human demographic changes as a result of the ice caps melting.

At first thought, especially during the cold winter months, a little warming wouldn’t seem to be such a bad thing. Several varieties of fruits and vegetables could be produced in northern climates that today only grow in warmer regions. Warmer seas are likely to be attractive to more species of fish to the colder habitats as well. This is not to mention additional tourist currency to what would be the warm, sandy beaches of Canada or England. However, this happy scenario will not be the case as the earth continues to warm. A chain of events will cause England to experience another ice age. The melting ice caps will combine with other sources to pour fresh water into the oceans. This will end the oceanic cycle that currently warms Northern Europe. This discussion explains the greenhouse effect and the various ways it will impact human demographic changes. Of course, global warming will affect many different aspects of human life in ways that is only open to speculation. The rising seas and melting ice caps are just one of the factors in a complicated equation.

Essentially, the greenhouse effect functions in the following manner. When sunlight pierces the atmosphere and hits the earth’s surface, not all of the sun’s solar energy is absorbed. Approximately a third of it is reflected back into space. Specific atmospheric gases serve in much the same way as does the glass of a greenhouse, thus the terminology. These gases allow sunlight to penetrate then trap some of the solar energy which heats the earth (Breuer, 1980). It is a delicate balance and because these greenhouse gases have been artificially augmented by man-made sources, more build up in the atmosphere has occurred thus trapping more of the sun’s energy and reflecting less back in to space. This occurrence is causing the earth to warm. If the balance between the CO2 levels in the ocean and atmosphere is
