The Causes and Effects of Global Warming
If you’re accustomed to thinking of global warming as something happening out there--say, in the Artic or the Antarctic or high in the atmosphere--you may be in for a shock.(Silvestro.) Global warming is the observed and projected increases in the average temperature of Earth’s atmosphere and oceans (wijkman). Today, this is one of our most damaging problems (Global). Global warming is caused by the buildup of atmospheric gases and affects us in many ways such as, the rising of long term global temperatures and the economic damages it causes. Among our world leaders, global warming has become a major issue.
A main cause of global warming is the buildup of atmospheric gases increasingly emitted by human activities, mostly the burning of fossil fuels. Moreover, Carbon-dioxide is considered to be the most eminent of the gases (Silvestro.) It is used by plants in photosynthesis, the process by which they turn sunlight into vegetable energy. The gases are built up by a series of things such as the green house effect. In fact, “the green house gases trap some of the energy that would have otherwise escaped.(Bishop) “Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually”(Global).Therefore, if our countries follow the path of our industrialized nation and invest in fossil fuel generation technologies, our world carbon dioxide emissions could soar(wiljkman). Negotiations have gone on about the reduction, and an agreement has been made. It was expected to be signed in Kyoto, Japan.
Because of this, the rising of long term global temperatures has increased. Not only is global warming affecting everything around us, soon we will be able to feel the heat at our dinner table. (Silvestro.) For example, in the first half...
