The given graph shows the size of ozone hole over Antarctica and the amount of three 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 was slightly increased. But the average release of CFC-11 was declined.
The range of Ozone hole increased from around 50,000 km square to 20,000 km square from 1980 to 1990. Followed by a decline to roughly 10,000 km square in the next three years. However, the drastic growth was witnessed afterwards, and the size reached to 40,000 km square in 2000. Which was 8 times more then 1980.
The amount of CFC-11 emission was the highest in 1980, at 70 million tonnes. It remains stable for next three years. Then it experience a continuous decrease over the period, to less than 10 million tonnes in 2000. Then production of CFC-12, on the contrary, it remains a slow increase from 30 million tonnes to 40 million tonnes around the entire period. N2O, however, it only appeared in 1992, it almost increased dramatically from 0 to 30 million over ten years. Which is might have contributed to the increase the hole of Ozone layer after 1992.
