Study Highlights Need to Monitor the Ozone Hole

In an article posted on https://phys.org about the Antarctic ozone hole, “University of Otago researchers believe chlorofluorocarbons (CFCs) aren’t the only things to blame.” This study highlights need to monitor the ozone hole.

“Lead author Hannah Kessenich, Ph.D. candidate in the Department of Physics, says they found there is much less ozone in the center of the ozone hole compared to 19 years ago.

This means that the hole is not only larger in area, but also deeper throughout most of spring.

“We made connections between this drop in ozone and changes in the air that is arriving into the polar vortex above Antarctica. This reveals the recent, large ozone holes may not be caused just by CFCs,” she says.”
