In his essay, Sanford does state relevant,
indisputable facts about the greenhouse effect and the increase in greenhouse gases that have occurred over the last century. These are the only areas that Sanford is in agreement with the text. There is enough evidence showing that there is a definitive increase in CO2, one of the major contributors to greenhouse gases, since the industrial revolution began. Scientists have monitored increasing levels of CO2 from the top of Mauna Loa, Hawaii, since 1958 to present. This is the first time that CO2 data has been recorded for this length of time and should prove useful for future global warming analyses. This is where Sanford departs from the global warming, drum banging text material. If I were to read through the text without reviewing opposing views, I might have my cars for sale on e-bay while looking to purchase a rickshaw so my children could pull me to work.
