Excessive release of

CO_{2}

into the atmosphere results in:

(A)formation of smog
(B)depletion of ozone
(C)global warming✓ Correct
(D)polar vortex

Answer: (C)

Solution

Carbon dioxide is a greenhouse gas: it lets sunlight through but absorbs the infrared that the warmed Earth radiates back, trapping that heat near the surface. Releasing it in excess thickens this blanket and raises the average surface temperature, which is global warming.
