It is time to summarize, and it is time to answer the
question. So "The Ozone Hole: Does it matter or not?". I still think
that it does matter.
Looking back at our previous blogs, from the very beginning, we know that the ozone hole has developed and started to shrink. In this November we received news from NASA that the ozone hole had reached the lowest level since 1980. Everything seems to be moving in the right direction, as if humanity's efforts to protect the environment have achieved great success. But when we look at the principles of the formation, development and reduction of the ozone hole, we can no longer maintain a very optimistic attitude. The formation of ozone hole mainly attributes to chemical reasons (Freon, etc.), solar activity causes, the reasons for atmospheric movement and other natural activities (such as volcanic eruptions), a large part of which is beyond human’s control. Humans have limited some of the known major ozone consumption, but new short-lived ozone depleting substances have been discovered without norms and limitations of their use. The reason why the ozone hole is the smallest this year is the abnormal warming in the stratosphere. This means that the seemingly good aspects may only be temporary; while global warming which can be mutually reinforced with the stratospheric ozone hole, is not temporary. In other words, the ozone depletion will recover slowly if global warming cannot be stopped.
Therefore, the whole world should still firmly stand together and contribute to preventing the ozone layer from continuing to grow larger. Although volcanic eruptions or solar activity are beyond control, it is impossible to improve the process of global warming and limit newly-discovered ozone depleting substances.
