This paper describes the causes of the global warming phenomenon that have been a part of earth's geological history since the dawn of geological time. The paper also looks at the effects that global warming has on the earth and in particular its effects in the Arctic Circle.
From the Paper:
"Climate change in general, and global warming in specific, are by no means new phenomena. Since the dawn of geological time, surface and atmospheric temperatures on Earth have fluctuated enormously. In some cases, worldwide climate change has led to actual shifts in land masses, leading to changes in the ways human beings and societies evolved. For example, global climate change caused the so-called Ice Age: "During the Quaternary period (the past million years) the ice cap has repeatedly spread to middle latitudes over the sea, with corresponding glaciation on the continents," (Gribbin Forecasts 73). The disappearance of the dinosaurs and other prehistoric creatures may in fact be due to climatic changes. Global warming has also been intense in our geological history: between ice ages, it is possible that no portion of the earth was covered with glaciation whatsoever (Gribbin Forecasts 73). Moreover, such massive temperature and climate transformations probably did not occur as a result of human intervention, but rather were a result of complex environmental, meteorological, and astronomical influences. Climatic fluctuations are indeed natural and inevitable."
