Human Impact on the Greenhouse Effect Research Question: How does petroleum emission affect the atmospheric carbon dioxide levels in the years 1959-1968 compared to 1997-2006? Hypothesis: Carbon dioxide levels are likely to rise in more recent years because the amount of machines that use petroleum has increased and so forming more pollution in the atmosphere. Variables: - Atmospheric carbon dioxide data is only from Mauna Loa Hawaii and not from the whole United States of America. - The petroleum data is from the United States of America so therefore it is a mean value and not specific amounts of petroleum emissions in a certain area. - Only the emission of petroleum is compared to the atmospheric carbon dioxide levels even though there are other carbon based substances that could have an effect on the carbon dioxide levels in the atmosphere. Therefore the amount of data that can be processed is limited to one sector of environmentally harmful materials. Data Selection: After taking a closer look at the data from Mauna Loa, Hawaii regarding the atmospheric carbon dioxide I decided ...read more.


[Figure 1 - The amount of petroleum emission in million metric tons of carbon dioxide during the years 1959 to 1968] [Figure 2 - Atmospheric Carbon Dioxide levels in Mauna Loa, Hawaii during the years 1959 to 1968] There is a steady increase in the emission of petroleum [Figure 1] compared to the atmospheric carbon dioxide levels [Figure 2] where there are certain displacements in the graph for example in the year 1960 there is a noticeable increase by 1.43ppm. In 1961 there is a slight decrease in the atmospheric carbon dioxide level by 0.18ppm. From the years 1961 to 1964 there is a stable increase in carbon dioxide levels and then there is a sudden plunge in the graph in the year 1965. After that in the year 1966 there is a significant increase in the atmospheric carbon dioxide level. Comparing 1968 to 1959 there is a momentous difference of 7.2ppm showing the vast increase in carbon dioxide levels present in the atmosphere during the selected ten years. ...read more.


There is also a great increase of carbon dioxide levels during these 2 years of 58.85ppm. By using the data a possible conclusion is that as the years have increased the effects of petroleum have also had a great effect on the atmosphere. Conclusion: From the data collected it is possible to conclude that as the petroleum emission increases the amount of carbon dioxide levels in the atmosphere also increases. From Figures 1 and 3 we can also see an immense difference between the amounts of petroleum used during 1959-1968 and 1997-2006. The vast difference between the amounts of petroleum usage could be because of the increased amount of vehicles and industries that use petroleum causing the carbon dioxide levels to steep also. From Figure 3 there is an obvious decrease in petroleum usage between 2004 and 2006 but in Figure 4 there is no significant difference on the stable increase of carbon dioxide emission. This is probably so because other factors might have also affected the rising carbon dioxide levels proving that petroleum is not a minor however also not a major contributor to the atmospheric carbon dioxide levels. ...read more.
