uger, 2006). This excerpt illustrates the common fallacy of incorporating scare tactics, which are often used by advocates of global warming, to convince their audience that if they do not act immediately, something will go fatally wrong. Extreme exaggerations are also being used to illuminate the severity of the consequences of global warming. Meteorologist Dr. Gray claimed that the hype concerning global warming is “ridiculous” and supported by “people who don't understand how the atmosphere works” (Herron). There are many other scientists who are opposed to the whole global warming consensus of today. (Al Gore Debates Global Warming). Dr. Syun-Ichi Akasofu, the director of the International Arctic Research Center of the University of Alaska Fairbanks, is one. Dr. Tim Ball, a former professor of Climatology at the University of Winnipeg, is another. Both these scientists point out how rises in the temperature and CO2 levels are often reversed. Audiences need to analyze the contemporary literature on global warming more critically to verify that they do not become merely a product of the fickle media.

  

Does CO2 Cause Global Warming?

Although it is true that levels of carbon dioxide and surface temperatures are correlated, it is not true that CO2 is the major cause of this rise in temperature. In fact, many respected scientists such as Ian Clark, Syun-Ichi Akasofu, and Tim Ball claim that temperature fluctuation actually precedes changes in carbon dioxide levels. The fact that temperature changes precede changes in carbon dioxide levels demonstrates that temperature affects the CO2 level, and not the other way around. Scientists such as Ian Clark and Nir Shaviv have both affirmed that according to analyses of the past, CO2 has a very minimal effect on temperature change.

 

For example, Ian Clark, an Earth Science professor at the University of Ottawa, mentioned that if “we look at climate through the geological time frame, we would never suspect CO2 as a major climate driver. We can't say that CO2 will drive climate. It certainly never did in the past.” Piers Corbyn, a weather Forecaster who works with Weather Action, affirmed that “(n)one of the major climate changes in the last thousand years can be explained by CO2.”. University of Virgina Patrick J. Michaels, who is also a member of the IPCC and the Department of Environmental Science, claims that “(a)nyone who goes around and says that carbon dioxide is responsible for most of the warming of the 20th century hasn't looked at the basic numbers.” According to Associate Professor of Physics Nir Shaviv from the Hebrew University of Jerusalem, “(t)here were periods… in earth's history when we had 3 times as much CO2 as we have today, or periods when we had ten times as much CO2 as we have today, and if CO2 has a large effect on climate, then you should see it in the temperature reconstruction.” (“Al Gore Debates Global Warming”).

 

Further, contrary to popular belief, there is no real scientific proof that increased CO2 本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
