Global Warming: History and Effect

Paper Summary:

This paper explains that the concept of global warming caused by the elevation of carbon dioxide in the atmosphere was first issued in 1896, again in the 1970s and, by the 1980s, global warming again became the rage. The author points out that there are still individuals who claim that there is no reliable scientific data to support the global warming theory and state that scientists have only based their assessment on computer models; yet, scientific evidence shows that since 1860 the earth is warming. The paper relates that, despite this evidence of global warming, there remains uncertainty and debate among environmental groups, scientists and policymakers on its specific impact on the atmosphere; there is not one commonly known way to reduce carbon in the atmosphere.

From the Paper:

"The 1990s were probably the warmest decade in the last 1,000 years, and much of the increase of the last millennium took place in the past 30 years. Scientists believe that greenhouse gas emissions from human sources are contributing to this worldwide warming trend. If greenhouse gas emissions continue unchecked, they predict that Earth, on average, will warm 2 to 6 degrees Fahrenheit by the year 2100. This could result in increased heat waves, droughts, forest fires, disease and sea-level rise leading to flooding of coastal areas."
