Global Warming: Fact or Fable? Essay

Throughout history global warming has been on peoples minds. Global warming is “an increase in the volume of carbon dioxide in the atmosphere, contributing to a “green-house” or insulating effect that traps heat from the sun’s rays and raises the average temperature around the world” (Viotti and Kauppi p 543). Some causes of this environmental threat are: pollution of harmful gases in the atmosphere, deforestation, and technological advances. The effects to the human population, animals, and agriculture could be dangerous. There are people who believe this is happening and something needs to be done. Then there are people who say global warming is a myth and our global society is not in any eminent danger. So my question is: Is global …show more content…
Arrhenius researched the effects of carbon dioxide on the atmosphere while working on the cause of the Little Ice Age, and presented a theory to his peers at the Stockholm Physical Society. His theory called “On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground” (NASA). The Little Ice Age is defined as “The period from about 1400 to 1900, characterized by expansion of mountain glaciers and cooling of global temperatures, especially in the Alps, Scandinavia, Iceland, and Alaska” (American Heritage). He describes how carbon dioxide and the earth’s water vapor gives off energy and changes the atmospheres conditions. As he measured and examined different formulas, he found that the temperature in the glacier areas rose when the carbon dioxide was increased. “In order to get the temperature of the ice age between the 40th and 50th parallels, the carbonic acid in the air should sink to 0.62 to 0.55 of present value” (NASA). Arrhenius had predicted the increases in the carbon dioxide and temperatures but thought the outcomes to be slightly different with the amounts. From his calculations the earth’s temperature would be warmer than is currently is and the carbon dioxide levels would be lower. Arrhenius wanted to reach more people to inform them of a new theory called “the “hot-house” theory of the atmosphere,
