CAR - Living in a dynamic earthEssay first draftEvolving from ape-man society to the advanced civilization nowadays, people start to inhabit in artificial concrete jungle and live far away from the given natural environment. With social progression and economic benefits, peoples' crave for natural resources keeps escalating from time to time. People have a great tendency to consume resources yet ignore the long-term behavioral ...view middle of the document...
This chapter specifically links the variation of solar radiation to the changes on surface of the Earth and history of mankind. The aforementioned changes in solar radiation are explained by long-term cycles. (Chapter 1, P.5) With obtaining the trapped gas of carbon dioxide in ice to determine the information about the changes in atmospheric temperature, in which a 100,000 years of slow cooling in glacial periods and 20,000 years of rapid warming in interglacial periods can be investigated. Climate changes create different periods and with the start and end of different periods generate distant consequences hence affect and shift living of human. From the long history of 1,5000 years ago, increasing temperature leaded to the melting of water and terminated the last Ice Age. With the end of last Ice Age, three main consequences - topographic effects of deglaciation, peopling effect of the Americas and the possibility of the occurrence of biblical flood in the Black Sea occur. (Chapter 1, P.15) These three effects further mold the surface of the Earth with the junctions of rivers, separation of the Earth continents and expansion of sea area. Firstly, 'topographic effects of deglaciation' discusses the physical evidence of glaciation on land and rapid sea level rise. The melting of ice uncovered the land and exposed much of the topography of North America and northern Europe. Secondly, 'peopling of the Americas' confers the idea of very different evolution patterns between South and North Americas using examples of primates, hominins and Homo sapiens. The circumstance was leaded by the isolation of North America by the opening of the Atlantic and Arctic Oceans. Thirdly, 'Flooding of the Black Sea' tells that the Black sea was once isolated, and by connecting the Black Sea with other world's ocean by melting ice, the busiest waterway in the world that affects people's transportation routes and preferences is created. Then from the shorter history of past 2000 years, the time is divided into five periods with obvious evidence of the influence of climates to human behavior and history. (Chapter 1, P.17) For example, in the Little Ice Age, a decrease in food production and rise in food prices due to a cold climate spurred the emigration of people and eventually the high food process leaded the French Revolution. It is evident that although it seems irrelevant, when viewing the human history and climates together, we can find huge and direct relationship that can by no means be overlooked. Climate changes human behaviors and builds history. After explaining the linkage between climate and human activities, global warming is discussed as a non-stop phenomenon that keeps influencing us. After showing evidence of global warming, it is, however, stated that the rapid increases of the amount of greenhouse gases is mainly caused by human activity and social progression. For instance, in the 1700s, the industrial revolution started up the human economic...
