D. Chicago, Illinois
E. London, England
China uses a great deal of coal in providing energy. Gray-air
smog is a result of burning large volumes of coal.
You might have been tricked by Los Angeles, California. But
Los Angeles has thermal inversion and regular smog, not gray-
air smog

17. • Which of the following gases involved in global climate
change is increased in the atmosphere at the fastest rate?
A. H2O
B. Methane
C. Chlorofluorocarbons
D. CO2
E. O2
CO2 is rising most rapidly due to global warming. It is
