Comparing & Contrasting Two Graphs

     I am writing this blog to compare and contrast two charts from the book, The Climate Casino by William Nordhaus. The first chart is located on page 33 and its about CO2 emissions from fossil fuels and the second chart is on page 47 and it is about global mean temperature increase.

     When looking at the first graph on page 33 you notice that both the Yale DICE model and the average of EMF models predict an increase of CO2 emissions from fossil fuels. Growth rates of CO2 emission range from 0.5 percent and 1.7 percent per year from the 2000-2100 period. Based on the chart the emissions of CO2 in 2100 range from 1.6 to 5.4 times higher than in 2000. On the second graph on page 47 it shows the global mean temperature increase. The graph received its data from DICE (RICE) model and the average of the EMF-22 integrated economic models. The graph shows a very high global mean temperature increase from 2000-2100. The average temperature in 2100 is 3 1/2 degrees Celsius above the 1900 average, according to both the EMF and the DICE model estimates. 

     Both Charts show a link between the rise of the global temperature and CO2 emissions of fossil fuel. Both the Yale DICE model and the average of EMF models predict that we will continue to increase the amount of CO2 emissions from fossil fuels causing the global temperature to continue to rise.
