Ozone hole dynamics in recent years

April 20, 2017

Let me remind you that the ozone hole is the area of ​​the stratosphere over the Antarctic, where every spring (in the northern hemisphere this autumn) the ozone content decreases, resulting in all living organisms under it, get an increased dose of ultraviolet radiation.

In recent years, there has been a tendency to reduce the area of ​​this negative natural phenomenon. This can be observed in the attached figure, and in numbers it is expressed as follows: from 2000 to 2016, the area of ​​the ozone hole decreased by 4.5 million km2. The obvious exception is 2015, when a hole of 28.2 million km2 was formed. This is 4.1 million km2 more than the size of the 2014 hole.

But last year, the hole was formed significantly smaller, which gave rise to moderately optimistic forecasts for its final disappearance. Some American geophysicists believe that the complete overgrowth of the hole may be completed by 2050. There is reason to believe that the 1987 treaty on reducing emissions of ozone-depleting compounds contributed to the international treaty.
