The graph illustrate the size of the ozone hole layer over Antarctica and the amount of three different types of gasses that damaged the layer from 1980 to 2000.
Overall, the size of the ozone layer grows over the entire period. The production of CFC-12 and N2O was increased but the average release of CFC-11 was declined.
The size of the ozone hole increased from around 500,000km to 2,000,000km from 1980 to 2000, followed by decrease to roughly 1,000,000km in the next 3 years. However, a drastic growth was witnessed afterword, and the size of reached 4,000,000 km in 2000, which was around 8 times more then in 1980.
The amount of CFC-11 emissions was the highest in 1980, at about 70 million tones0. It remains mostly stable from 1980 to 1983, then experienced continuous decrease over the period, to less then 10 million tones in 2000. The production of CFC-12, on the contrary, remained a slow increase from 30 million tones to about 40 million tones in 2000. N2O however, only appeared after 1990, increased dramatically from 0 to 30 million tones over 10 years. Which might have contributed to increase of the ozone hole after 1993.
