The graph illustrates the size of the ozone hole over Antarctica. And the amount of 3 different types of gases that damaged the layer from 1980 to 2000.
Overall, the size of the ozone hole grew larger over the entire period. The production of CFC-12 and N2O is increased. But the average release of CFC-11 declined.
The range of the ozone hole increased from around 50,000 km to 20,000 km from 1980 to 1990. Followed by a decline to roughly 1,000,000 km in the next 3 years. However, the drastic growth was witnessed afterward, and the size reached 4,000,000 km in 2000. Which was around 8 times more than in 1980.
The amount of CFC-11 emission was the highest in 1980, at about 70 million metric tonnes. It remains stable for the next 3 years. Then experienced a continued decrease over the period, to less than 10 million tonnes in 2000. The production of CFC: 12. On the contrary, there remains a slow increase from 30 million metric tonnes to about 40 million metric tonnes. N2O, however, only appeared after 1999, and it almost increased dramatically from 0 to 30 million metric tonnes over the 10 years; this might have contributed to the increase of the ozone hole after 1992.
