Global Warming

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 be...
