Global Warming Essay Example for Free

Global Warming EssayGlobal Warming is an issue that concerns al near everybody ecumenic it is the primary bring on for the erratic and virtuallytimes devastating weather that is experienced around the world. Global sort is causing the rise in sea level which in turn causes the flooding of coastal areas and areas with wretched elevation. Is world(a) warming really happening today? Scientists with the United Nations environsal Program (UNEP) believe it is so. It is certain that there has been a rise in the concentration of greenhouse featurees (GHG) in the atmosphere during the last century, which scientists imagine may be one of the causes of global warming. II. Discussion A. Global Warming and doomsday Will global warming spell doom for our world? Scientists believe this to be so. Much depends on what actions we take instantaneously and in the coming years. Meteorologist Jagadish Shukla of the University of Maryland found out that deforestation would cause rainwater fall in the virago River to decline by more than 26 percent from the current 2. 5 m. to about 1. 8 m. a year. At the same time, the burning of fossil fuels, particularly coal and oil, produces sulfur dioxide and nitrogen oxides which are wild to the atmosphere.Findings show that a single smokestack may produce as much as calciferol tons of sulfur dioxide a day. When these gases combine with oxygen and moisture, sulfuric acid and nitric acid is formed. The rain will carry the acids to the ground (acid rain) which may cause the depletion of calcium and magnesium in the soil, elements needed by plants for the formation of chlorophyll and wood, or it may cause the release of aluminum in the soil, which are pestilential and can kill the roots of trees (Carwardine, 2000). According to Dr.Sadik, UN population funds director, said that the more mass increased pressure on already stressed lands, forests and water supplies. Other sources of climatic change were attributed to some forms of gases such as nitrous oxide, methane and chlorofluorocarbons (CFCs) (Cronin, 2001). Nitrous oxide or laughing gas is a colorless gas with a sweet taste and odor that is used as an anaesthetic in minor surgical operation that H2O is responsible for about 6 percent of the human contributes to greenhouse warming.Methane or cow gas, on the other hand, makes up about 18 percent of human contributions to greenhouse effect. Cattle, sheep, goats, and other cud-chewing animals give run into methane, in burps and flatulence as they digest. CFCs was discovered by Thomas Widgley Jr. , a chemist working(a) at the Frigidaire Division of General Motors, used as coolants in refrigerators and air conditioners and aerosol propellants in dot cans, medical sterilizers, cleaning solvents for electronic components and raw materials for making plastic foams such as coffee cups.CFCs are estimated to account for 14 percent of global warming. Experts said that what is happening right now is not a matter of adding a few degrees to the average temperature of a community. A rise of this magnitude may cause life, for without the environment, creatures on earth cannot survive (Davidson, 2003). B. Recommendations a. ) Recycling and Reuse of Solid Wastes Solid wastes are now viewed as a potential resource which must be recovered and reused whenever possible. Since disposal forest resources are quickly being depleted, recycling solid wastes offer a solution to both.Consider the element phosphorus. Mined from orthophosphate ores, it is manufactured into fertilizers. It enters the plant tissues and we obtain it when we eat plant as vegetable. This is later excreted and joins the sewage form. The sewage system sludge can be used directly as fertilizer or soil conditioner. b. ) Conserving our Forests any now and then we receive alarming news about our forests being denuded. Big logging concessionaires promiscuously cut down trees without undertaking reforestation measures. III. Conclusio nOf all issues affecting humanity, climate change is the most pervasive and truly global, posing a very real and serious threat to our environment. Climate change is the alteration of the pattern of global climate that may be due to human activity that alters the man of the atmosphere. If toast day emissions of greenhouse gases continue, it is estimated that the rate of increase in global mean temperatures will go on about 0. 3o C per decade. This will mean a likely increase of 1o C above the present level by the year 2025, and 3o C before the end of the next century.Reference1. Carwardine, Mark (2000). The WWF Environment Handbook.
