Although there is a natural cycle, the pattern is being altered due to effects of harsh chemicals exposed to the atmosphere beginning in the Industrial Revolution. Science has repeatedly proven the existence of global warming, however the battle to convince the public is no longer scientific. ... The notion of climate change has accumulated support in recent years, but the presence of temperature heating beyond the normal cycle has been present since the time of the Industrial Revolution and only gained the political aspect years later. However, it was not until the 1950s when scientific findi...

Many aspects, however, have already been discounted by the scientific community. ... Over 17,000 scientists have signed a petition saying, in part, "there is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate" (Roleff, 1997). ... Since the industrial revolution, atmospheric concentrations of carbon dioxide, methane and nitrous oxide have risen, enhancing the heart-trapping ...

According to John Houghton, Co-Chairman of the Scientific Assessment of Climate Change, "the basic principle of global warming can be understood by considering the radiation energy from the sun which warms the Earth's surface and the thermal radiation from the Earth and the atmosphere which is radiated out to space" (Houghton, 12). ... "Since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have risen 15%" (U.S. ...

Later on, McKibben started talking about the Industrial Revolution and the negative impacts on our ecosystem; the concentration of carbon dioxide that was once 275 parts per million is now 380 parts per million, meaning that there is already more carbon dioxide in the atmosphere than there has been for twenty million years. ... The poor word choices; specifically the scientific terms, requires a better knowledge in the filed of science in order for you to fully comprehend what McKibben and Zakin are trying to say. ...
