Is the atmosphere of our planet warming consistently, and at a more rapid pace than ever before, and is it being caused by human consumption? This question is the basis for the dispute on Global warming. It is this century’s largest debate. There are scientists, politicians, and civilians on both sides of the debate. Scientists have determined that the Earth has cooled off and warmed up several times over its long history. I do not believe that a reasonable person would deny that there is the potential for the Earth to repeat this pattern at some point in the future. The real point of contention is then in reference to the cause. Some scientists believe they have found a correlation between an increase of carbon dioxide in the atmosphere and a link to the hypothesis once known as global warming, and now called climate change. There are scientists who reverently believe that fifty percent or more of the rapid increase in surface temperatures of the Earth are caused by humans. They believe that the increase in our usage of fossil fuels to drive our advanced economies has caused the levels of carbon dioxide to proliferate out of control. In order to comprehend the debate, an understanding of the term green house effect is required. There are gasses in our atmosphere that trap heat in, and don’t allow it to escape into the cold depths of space. Without the green house effect the earth’s surface temperature would hover below the freezing mark. This occurs much the same way a green house helps plants to grow in colder climates. The Earth is constantly bombarded by the sun’s rays that permeate through our atmosphere to warm it. Some of this intense heat is absorbed by the Earth’s surface and some of it is reflected and returned bac... ... middle of paper ... ... ranging back eight hundred years.
