Environmentalists claim that the science is established and that any steps taken to prove otherwise will be unsuccessful. They do this to distract the public from the fact that much of their data is deliberately taken out of context, manipulated or fabricated in order to prove that human-caused global warming exists. In fact, there is more evidence showing that the increase in temperatures could be due to solar activity or part of Earth's natural climate fluctuations, rather than arguing that it is caused by greenhouse gases. man-made greenhouse. The global warming debate encompasses one of the most complex systems in our natural world, the Earth's atmosphere, so it is very important to understand the basics. In the book The Science and Politics of Global Climate Change, climate is defined as "The climate of a place, region, or Earth as a whole, is the average over time of the weather conditions that occur y produce – average time” (Dessler and Parson, 2010, p. 7). The source of energy for Earth's climate is electromagnetic radiation, specifically the sun. This means that the sun is the main driver of climate, unless something else is acting on it. According to environmentalists, humans change the climate through our actions. The official definition of human-caused climate change is given by the United Nations report "Framework Commission on Climate Change" as "climate change attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is further related to the natural climate variability observed over comparable periods” (Bell, 2011, p. 45). According to environmentalists, the primary way humans change the climate is through the greenhouse effect. Green...... middle of paper ...... has been removed by the Environmental Protection Agency. Carlin, who was a senior research analyst at the EPA, wrote his “Internal Climate Study” report. After reviewing all the research compiled by the EPA, he concluded that the available data invalidated the theory of human-caused global warming. He wrote: “Given the downward trend in temperatures since 1998, there is no particular reason to rush into a decision based on a scientific hypothesis that does not appear to explain most of the available data” (Bell, 2011, p. As a result of his findings, thirty-eight-year-old employee Alan Carlin was banned from speaking to anyone about his report and removed from all climate-related work. Shortly after the report was suppressed, the United States adopted the Endangerment Findings of the Clean Air Act, which allows it to set limits on greenhouse gases produced by the American people...
