Debate Paper # 1 (Climate Change) Our atmosphere originally possessed the characteristics of a natural supply of greenhouse gases; these are responsible for capturing heat and keeping the surface of earth warm enough for human beings to live on. Pre- Industrial Revolution, the amount of carbon dioxide and other gases released into the atmosphere was in a rough balance, with what was absorbed in natural sinks. Without the greenhouse effect the planet would be uninhabitable, for example plants take in CO2 when they grow in the spring and summer and release it when they die and decay in fall and winter. When the Industrial Revolution began in the mid-1700s people started to put out large amounts of greenhouse gasses. As more people began to drive automobiles and more fossil fuels were burned to run factories and many other things, it added to the greenhouse gases natural supply, that have been in the atmosphere for centuries. Because of this it’s creating an extra thick blanket around the earth, resulting in the earth heating up about one degree Fahrenheit over the past one hundred years, but the intensity has increased within the last two decades. Many scientists are convinced that for the last decade the earth has been getting warmer. Sometime in the 1850’s there were a few weather stations placed around the world compiling temperature records. During the twentieth century as well as today there are thousands of land based stations, as well as ocean buoy’s monitoring temperatures around the globe. Temperature Records since the 1850’s clearly show the warming of earth for over a century. (Source-EDF-environmental Defense Fund. N.p. Web. 2 Feb. 2013.) How do we know if human activity is causing Global Warming? Scientists have explained all factors that explain the effects of earth’s temperature; One man thought that he knew that...
