Global Warming

Global Warming, Climate change in America, should we worry or just live one day at time? The issue of global warming first came about when scientists became aware of the amount of carbon dioxide being added to the atmosphere as a result of human activity. Global warming is an increase in the earth's atmospheric temperature due to fossil fuel combustion, agricultural and industrial processes caused by human activities. The result is an increased release of various greenhouse gases, such as carbon dioxide into the atmosphere. Such greenhouse gases are a natural part of the atmosphere and play a vital role in the sustaining of life on this planet by helping to trap the sun's warmth, and maintain the surface temperature at a level necessary to support life. I believe that the greenhouse effect is correct; however I do not believe that Earth will die because of the increase in temperature and decrease of ozone.

Scientific studies on climate helped establish a c...

Life depends on the greenhouse effect which regulates the Earth's climate, keeping it stable enough to carry on life. Many gases display such "greenhouse" properties, including those that occur naturally in the atmosphere, such as water vapor, carbon dioxide, methane, and nitrous oxide, and those that are man-made, such as chlorofluorocarbons (CFCs) and hydro fluorocarbons (HFCs). By increasing the amount of some of these heat-trapping gases, we strengthen the natural greenhouse effect and further warm the atmosphere.

Scientist agrees that the Earth's surface has warmed by about 1 degree Fahrenheit in the past 140 years. The green house effect allows incoming solar radiation to pass through the earth's atmosphere, but it prevents most of the outgoing infra-red radiation from escaping into outer space. This process occurs naturally and has kept the Earth's Temperature about 59 degrees F warmer than it would otherwise be. Without...
