The U. S. Environmental Protection Agency definition of global warming: “Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere, which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes, both natural and human induced. In common usage, “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities (U.
S. Environmental Protection Agen). The first viewpoint that I would like to represent is the viewpoint for Global Warming. Those who agree with Global Warming suggest that 90% of global warming has been caused and is increased by human factors. It is also expressed that the hottest time period has been from the span of 2000-2009. During this time period it was a degree higher than it was in 1970. Another fact that has also been brought about is that the sea level has risen around one inch.
Although this may not seem like much of a difference, but if it continues it will cause a major problem around the year 2100 (Global). The second viewpoint that I would like to represent is the viewpoint against Global Warming. Those who are against Global Warming claim that the global climate computer models that those for Global Warming are too crude to determine any actual evidence to prove or disprove Global Warming. Also certain scientists against Global Warming claim that if there were such a thing as Global Warming that it may actually be beneficial to our planet.
Scientists against Global Warming also say that even with their most technological advanced tools they have noted no change in temperature within the last twenty-three years (American). My viewpoint, after reading several articles on Global Warming and from previous knowledge is that there is not enough evidence to support Global Warming. Scientific evidence that shows warming during certain periods of time falls well within the natural variation, and causes no need for the expectation of a significant global warming.Also, in the present day there is NO evidence that proves that man-made CO2 that causes global warming. Although there are several arguments made about Global Warming and the concern we should have for it, many of the scientists and associations contributing to Global Warming awareness just do not have the amount of data needed to convince people of its existence. My knowledge of science helped me be able to look at the articles that I researched and understand what I was reading.Without having any type of science background it would make it very difficult to understand the terminology and data that is submitted on both sides of the arguments. Also, I grew up in a household with a father who supported the global warming movement. I talked to him and why he believed what he believed. His beliefs and statistics that he used were contradicted when comparing those to the statistics I was able to find put out by non-biased scientists who studied global warming and it validity.Thirdly, not only knowing scientific terminology, understanding the concept of global warming from an early age because it is a personal issue, but also understanding the history of science helped me to understand former studies on global warming and relate them to the present studies to determine the validity of global warming.
