CFCs have been largely replaced with HFCs in refrigerators and in home and
car air conditioners. HFCs are up to 1000 times better than carbon dioxide at
retaining atmospheric heat. The increased warming of the stratosphere
speeds up the chemical reactions that destroy ozone molecules. Which of the
following is a likely environmental problem if HFCs are not phased out?

1. Initiation of a new ozone hole
II. Continued ozone depletion
III. Accelerated global warming

A. II and III only
B. I only
C. I, II, and III
D. I and II only

Answer: A. II and III only

Explanation:

Ozone molecules get depleted as the stratosphere is warmed up. This means that the increased presence of HFCs will cause the ozone to continue to be depleted as its molecules are being destroyed by the higher temperatures.

HFCs also lead to accelerated global warming as they trap more heat than carbon dioxide which means that they prevent more heat from being released into space but rather keep them in the planet thereby increasing temperatures/ global warming.
