Part I (Thesis): Global Warming: A Natural Occurrence

There are always two sides to every story and every different point of view has a right to be heard. When it comes to the discussion of global warming—a gradual increase in the earth’s surface temperature—there are two very distinct and opposing points of view. The world seems to be split between global warming being caused by humans and it being a natural occurrence; the latter being the viewpoint that I strongly support due to the evidence I will present in detailin this paper. In contrast, I will also discuss, in Part II, the “anti-thesis” or the opposing viewpoint that humans are actually the cause of thisglobal warming phenomenon. Finally, in Part III of my paper, I will synthesize both viewpoints and discuss in great depth through much evidence as to why I believe global warming to be a natural occurrence that has happened and will continue to happen at different periods of time until the end of days. The first reason is that global warming comes and goes. The earth naturally heats up and cools down. Thirty years ago, we thought the biggest threat was global cooling and now the biggest threat is global warming. Throughout history, there have been numerous cooling and warming periods and we are now going through one of those natural warming periods, which have reached the warming levels of the Medieval Warming Period our ancestors experienced in the past, which I will explain in more detail later in this paper. The cycle of global warming and cooling has been happening long before humans have occupied the Earth and will continue to happen long after we are gone; it is a nature cycle that cannot be broken. The second reason why global warming is a natural occurrence is because the sun is what warms the earth. When the sun gets hotter, it makes sense that we get hotter too and this goes vice versa. If the sun is cooler, we get cooler. The sun has several cycles and the main one we see is the 11-year cycle, which I will explain, in greater detail in the synthesis portion of this paper. When the sun gets hotter there are more rays heating the earth, so the earth gets hotter. If we are so positive that global warming is a man-made problem, explain why Mars is also warming at the same pace as the earth is. Like Earth, Mars has also experienced warming and cooling periods throughout its history. The changes in the sun's heat output can account for almost all the climate changes we see on Earth and Mars; manmade greenhouse warming has made only a small contribution to the warming happening on Earth. The third reason why global warming is a natural occurrence is that manmade CO2 is not the main source of CO2 in the atmosphere. Again, this very interesting and intriguing fact will be furtherexplained later in this paper. I believe this will surprise you, once you read the facts regarding the sources of CO2; these factors were a highly significant reason that led me to oppose humans being the actual cause of global warming. In fact, the largest source of CO2 is the ocean (Broadgate, W., et. al., 2009). We only contribute 3.5% of all CO2 in the atmosphere, while the other 96.5% is released by natural sources. Therefore, as you see, the contribution of human made CO2 is very insignificant and has very little effect on global warming. In the end, you should be able to understand why global warming is not the result of mankind abusing the Earth, and that it is, in fact, a natural cycle that has been repeated throughout history. Global Warming comes and goes. The earth naturally heats up and cools down. Right now, we are going through a natural warming cycle, which will soon befollowed by a cooling cycle. The sun is always going to control how hot and how cool it is on the earth. Scientists need to consider this; if the sun is hotter, we experience hotter temperatures; and when the sun...
