Argumentative Essay on Global Warming
Is Global warming a real threat? “Global warming is the increase in the average temperature of the Earth’s surface” (Global Warming Nasa.) It has the effect of making the Earth’s surface warmer compared as it was the previous years. This effect is also referred to as the “greenhouse effect.” Accordingly to Global Earth Science, “the global average temperature has increased about 0.7 to 1.4 degrees F (0.4 to 0.8 degrees C) since the late 1800's and many experts estimate that the average temperature will rise an additional 2.5 to 10.4 degrees F (1.4 to 5.8 degrees C) by 2100 in which, that rate of increase would be the largest increase ever recorded in history. First, I am going to start off how it works. The Constitutional Rights Foundation explained how the “greenhouse effect” works: “Radiation from the Sun in short wavelengths easily pass through the Earth's atmosphere and strike the surface, which reflects much of it back as longer wavelengths” (Global Warming: What Should We Do About It?). “Instead of going back into space, the longer wavelengths are absorbed by gases in the atmosphere.” “The atmosphere reflects back to the Earth's surface a significant amount of the trapped radiation, which becomes heat.”

There are many possible causes of global warming. However, for the past several years, NASA noted “that most of the causes of global warming are man-made activities.” The “burning of fossil fuel is the top list of man made activities that largely contribute to global warming and this occurs in automobiles, in factories, and in electric power plants that provide energy for houses and office buildings” (Global Warming NASA). The burning of fossil fuels produces carbon dioxide , a chemical element that “slows the escape of heat into space” (Global Warming Nasa). “According to the Intergovernmental Panel on Climate Change (IPCC's) report, CO2...
