Most of the world today regards the "global warming" as both real and dangerous.
            
Many aspects, however, have already been discounted by the scientific community. Fears .
            
of massive sea level increase, accompanied by many early discussion about global .
            
warming. Scientist afraid the sea level would increase onto land due to the melting of ice. .
            
It is now widely agreed that even the potential contribution of warming to sea level rise .
            
would be swamped by other more important factors (Moran, 1999). These factors include .
            
hazardous gases and pollutants.
            
     We are entering a period of global warming as a result of burning vast amounts of .
            
fossil fuels. By burning fossil fuels, "we are putting into the air more gases that act like a .
            
globe of glass around the planet" (National Geographic, 1990). The "globe of glass" is a .
            
mixture of all the fuels that remains permanently on the surface of Planet Earth. It is .
            
called glass because it prevents cooling air from entering causing the Green House Effect. .
            
Many scientists believe that human processes are contributing to global warming .
            
regardless of impact of natural cycles also causing climate change (Keller, 1999). The .
            
earth's climate is predicted to change because human activities are altering the chemical .
            
composition of the atmosphere through the buildup of greenhouse gases - primarily .
            
carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is .
            
undisputed. Although uncertainty exists about exactly how earth's climate responds to .
            
these gases, global temperatures are rising.
            
     Scientists on Hawaii's Mauna Loa have recorded steady increase in human activities .
            
such as burning fossil fuels. Most believe that the rising CO2 level will lead to higher .
            
global temperatures and significant climate change (National Geographic, 1990). Some .
            
scientists do not believe this. Over 17,000 scientists have signed a petition saying, in part, .
