Students have asked these similar questions
(e) Which unstable, reactive species are responsible for the removal of CO from the
atmosphere?
(f) Carbon monoxide gas is more dangerous than carbon dioxide gas. Why?

The ocean will absorb the excess atmospheric CO2.
B)
Plant photosynthesis cannot compensate for increased atmospheric CO2.
C)
When tropical forests are logged, additional CO2 is released into the atmosphere.
