Ozone Hole Over Antarctica Expected to Get Larger

Here is an article about the Ozone Hole that sometimes is just over the Antarctic, although sometimes it ends up also over Australia and New Zealand. I found it interesting because before reading it I thought it was getting smaller or at least staying the same. According to the article the ozone hole is expected to deplete more as the sun rises again in Antarctica at the end of the winter darkness. It is not the CFCs that are expected to be the issue, but rather chlorine and bromine in the atmosphere.
