The sum of all CO2 emissions from 1850 to 2010, from fossil fuel emissions is equal to the total area under the graph from Problem 6-33.
a. Based on this method, how much CO2 was emitted from fossil fuels between 1850 and 2010?
b. How does this compare to the atmospheric increase in CO2 between 1850 and 2010, based on measurements of CO2 in ppm in the atmosphere between 1850 and 2010?
What will be an ideal response?
The total emissions can be approximated by calculating the shaded area from the graph, which is approximately equal to:
The additional atmospheric CO2 mass was calculated in example 6.1 to be 517 x 1012 kg or 517 GT, or 38% of the carbon dioxide emitted from fossil fuels remains in the atmosphere.
