Good Question: What Happened To The Hole In The Ozone Layer?

(CBS 5) – It protects life on earth from the harmful effects of ultraviolet rays. Peter DiAngelo of San Francisco asked this Good Question: Whatever happened to the hole in the earth’s ozone layer?

ANSWER: According to USF Professor Deneb Karentz, the hole in the ozone still exists but has indicated that it may be fluctuating.

Karentz said the ozone hole is still prevalent over the Antarctic at certain times of the year and peaked in 2006. The discontinued use of chlorofluorocarbons may finally be having an effect in reversing ozone depletion.
