Textbook Question
Chapter 56, Problem 9TYU
SCIENTIFIC INQUIRY (a) Estimate the average CO2. concentration in 1975 and in 2012 using data provided in Figure 56.28. (b) On average, how rapidly did CO2 concentration increase (ppm/yr) from 1975 to 2012? (c) Estimate the approximate CO2 concentration in 2100, assuming that the C02 concentration continues to rise as fast as it did from 1975 to 2012. (d) Draw a graph of average C02 concentration from 1975 to 2012 and then use a dashed line to extend the graph to the year 2100. (e) Identify the ecological factors and human decisions that might influence the actual rise in CO2. concentration. (e) Discuss how additional scientific data could help societies predict this value.
Figure 56.28 Increase in atmospheric carbon dioxide concentration at Mauna Loa, Hawaii, and average global temperatures. Aside from normal seasonal fluctuations, the CO2 concentration (blue curve) increased steadily from 1958 to 2015. Though average global temperatures (red curve) fluctuated a great deal over the same period, there is a clear warming trend.

The current concentration of CO2 in the atmosphere is about 415 ppmv. It has been estimated that annual anthropogenic additions to the atmosphere are about 30 gigatonnes (Gt), of which about 15 Gt are removed into oceans and the terrestrial environment. a) Use these values to estimate the yearly net increase in atmospheric carbon dioxide mixing ratio, in ppmv. (note that 1 Gt = 1015g)
Propose a reason why the CO2 fluxes are greater for terrestrial biological activity than for marine biological activity.
Environmentally conscious Susan has been told that a newelectric car will only generate 6 ounces of greenhouse gases (GHG) permile, but that a standard internal combustion car is double that at 12ounces per mile. However, the nature of electric cars is such that the new
technology and electric batteries generate 30,000 lbs. of GHG to manu-facture and another 10,000 lbs. to recycle. A standard car generates only
14,000 lbs. of GHG to manufacture, and recycling with established tech-nology is only 1,000 lbs. Susan is interested in taking a systems approach
that considers the life-cycle impact of her decision. How many miles mustshe drive the electric car for it to be the preferable decision in terms ofreducing greenhouse gases?
