This line graphs compose the change of size of Antarctica ozone hole and the trend of production of three different damage gases during two decades.
It is clear that the size of ozone hole in Antarctica was continuing increasing. Relating to the damage gases, except freon, NO2 and H2O2 had same trend as well as the ozone hole.
The size of Antarctica ozone hole expanded sharply from 80 thousands square kilometers to close to 100 thousands during 1985 to 1990 rather than other period. But in the last 5 years, it became steady.
According to the second graph, we can notice that there is no H2O2 in 1980, at the same time, NO2 and freon had 95 thousands metric tonnes and 150 thousands metric tonnes each. From 1985 to 1990, both NO2 and H2O2 were stable at 18 thousands metric toones and 105 thousands metric tonnes respectively. The freon peaked at 200 thousands metric tonnes in 1985, then it began to drop. A similar situation we can see in the NO2 and H2O2 in the last decade where the rate of increase reached at 4 times to 5 times. Comparing these 2 gases, the fastest rate of change is freon, from 1985 to 2000, it declined 9 times. In 2000, the freon only was 20 thousands metric tonnes, NO2 was 80 as the second, finally, NO2 was 160.
Overall, the connection between the size of Antrarctic and production of damaging gases is the more production of NO2 and H2O2, the less production of freon, the huger the hole is.
