Argument Speech: “For or against the case for man-made global warming” Y2K, May 21, 2011, December 21, 2012, what do all these dates have in common? A prediction about the end of the world. Many hear the words “global warming” and think the same thing. As Jonathan Kent in the recent Superman movie Man of Steel: “People are afraid of what they don't understand.” We don’t understand global warming, there is a plethora of propaganda, and uncertainty. What we do understand is that there are problems in every area of society...and we’re motivated by the fear that maybe we’ve messed up the earth itself too. This is especially true in the West, where some enjoy the luxuries energy has produced -- electricity, refrigerators and easily accessible clean water. A billion people currently live without what has become commonplace to us and we feel guilty about what we have, how we’ve allegedly used the planet to suit our needs. Caught up in the idea that life was simpler in a bygone era, some wish we didn’t have to deal with the “inconveniences” of technology -- the absence of which would leave us with an “unsanitary, difficult and short life.” Many believe that man is at fault for global warming. A Gallup poll in 2012, found that the majority of Americans agree.1 I disagree, the case for man made global warming is based upon man made fear and guilt, not man made

We will see this three points: 1) What is global warming? 2) What drives it and 3) A proper response
1) According to NASA: “Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released by burning fossil fuels.” The EPA explains that: “Greenhouse gases (GHGs) like water vapor (H2O), carbon dioxide (CO2), methane (CH4) absorb energy, slowing or preventing the loss of heat to space. In this way, GHGs act like a blanket, making Earth warmer than it would otherwise be. This process is commonly known as the “greenhouse effect”.

a. Proponents of man made global warming believe the increase in greenhouse gases will lead to the eventual end of the world. According to National Geographic, “Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace. It's becoming clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives.”2 b. 3 responses - water vapor, the sun, incomplete data: The largest, most abundant, most important contributor to the greenhouse effect, is water vapor which is completely natural, but makes up anywhere from about 75-95% of the earth’s warming effect.3 c. In addition, ozone, cloud cover, volcanic and sunspot activity, orbital movement, and solar system affect the warmth of the earth. As Dr. Jason Lisle, an astrophysicist from Answers in Genesis stated, The sun goes through warming and cooling cycles, that while not fully understood, impact the earth’s warmth. For example, the number of 1





sunspots varies over a 22 year cycle and higher sunspot activity is associated with higher temperatures on earth...For example, sunspot activity was very low during the period 1645–1715, at the depth of the Little Ice Age. In contrast, sunspot activity was high during the Medieval Warm Period.4 And Dr. Roy Spencer, climatologist and former NASA scientist, and supported by (National Oceanic and Atmospheric Administration) NOAA, and the DOE (Department of Energy) said “The recent warming cycle that started in the 1970s, might have been due to these natural causes, but we’ve only had the instruments to document this for about the last 10 years.5 d. Scientists claim data going back...
