Argumentation - Essay Example While many experts decry the negative effects of global warming, it is in fact turning out that global warming is a good phenomenon going by its numerous positive benefits. Scientists note that the earth’s temperature is rising undoubtedly as a result of the greenhouse effect. The atmosphere is saturated with carbon dioxide that traps heat leading to a steady increase in the earth’s temperature and consequently, changes in climate. This carbon dioxide does not come from outer space but from burnt fossil fuels such as oil, natural gas, and coal. The other factor contributing to global warming and climate change is the rate at which forests are lost, especially within the tropics as a result of deforestation. Scientists are overwhelmingly in agreement that global warming is a reality and that human activities are its main causes. (Union of Concerned Scientist par 6-7). According to scientists, each year, for the past 37 years, has been warmer than the average temperature of all the years in the 20th century. In the United States, the 12 warmest years have occurred since 1998 with 2012 standing out as the hottest years. Since the late 1800s there has been an increase of more than one degree Fahrenheit on the average surface temperature of the earth. The past three decades have experienced the lion’s share of this increase (Union of Concerned Scientist par 4-6). The current decade has been the warmest since 1880. Scientists note that the earth could experience a 7.2 degree Fahrenheit increase in temperature in the 21 century if nothing is done to curb global warming. This would be the case if emissions from fossil fuels such as oil and coal, which are the main culprits, not reduced. Scientists are worried that a number of negative consequences in relation to global warming are quite evident (Natural Resource Defence Council par1). For one, weather
