THE RELATIONSHIP BETWEEN CARBON DIOXIDE AND ANNUAL MEAN TEMPERATURE IN THE U.S.
Date: 05/10/2013 I Background
There is one of the most sensitive global climate issues for years, which is global warming. In general, we know that the origin of global warming is the emission of Carbon Dioxide. It was verified that the relationship between Carbon Dioxide and temperature: when there is more Carbon Dioxide the temperature gets warmer.
According to the 2007 Fourth Assessment Report by the Intergovernmental Panel on Climate Change, global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 20th century (Keppler). Because of the tendency of rising temperature during 20th century, we step forward and collect more data from 1990 to 2009, which is more representative for us to find out the relationship between Carbon Dioxide and Annual Mean Temperature, especially in the U.S. II Questions * Is there a relationship between Carbon Dioxide Emissions and Annual Mean Temperature in the U.S.? * If there is, whether the relationship is positive or negative? III Analysis
Data collected below is the Carbon Dioxide Emissions and Annual Mean Temperature in the U.S. from 1990 to 2009. Year | U.S. Carbon Dioxide Emissions | U.S. Annual Mean Temperature | 1990 | 5040.9 | 53.16 | 2000 | 5900.3 | 53.57 | 2004 | 6031.3 | 54.12 | 2005 | 6055.2 | 54.63 | 2006 | 5961.6 | 53.42 | 2007 | 6059.5 | 54.66 | 2008 | 5865.5 | 53.31 | 2009 | 5446.8 | 53.39 | 1. Analysis 1: Scatterplots & Correlation
Pair the data into the order of (x, y), which x value represents the value of U.S. Carbon Dioxide Emission and y represents U.S. Annual Mean Temperature. (5040.9, 53.16) | (5900.3, 53.57) | (6031.3, 54.12) | (6055.2, 54.63) | (5961.6, 53.42) | (6059.5, 54.66) | (5865.5, 53.31) | (5446.8, 53.39) | Input all the data into TI-84 Plus
