CO2 is a minor constituent in our atmosphere, with an abundance of less than 0.05% of the gases in this atmosphere. Why, then, is an increase in this gas considered to be important with respect to the continued viability of life on Earth?
(a) CO2 is poisonous, and an increase could endanger life on the Earth.
(b) An increase in CO2 will lead to less UV light reaching Earth from the Sun, thereby leading to a significant cooling.
(c) Small increases in CO2 will prevent more IR radiation from escaping from Earth, thereby leading to a dangerous warming of the Earth.
(d) CO2 causes acid rain, and an increase in CO2 would hurt agriculture and other human activities.
