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, .
