The line charts illustrate the size of the Antarctic ozone hole and three kinds of harmful gases causing damage to the ozone in the Antarctic from 1980 to 2000.
Overall, it is clear that the size of the ozone hole in the Antarctic witnessed a significant increase over the years. Additionally, while the production of Freon gas recorded a remarkable decline over the period, those of the two other gases experienced a reverse trend.
Regarding the size of the ozone hole, the figure began the period at slightly under 50 thousand square kilometres; however, it then showed a rapid surge to nearly 200 thousand square kilometres before reaching its peak at around 225 thousand square kilometres.
Concerning the hazardous gases harming the Antarctic ozone, the production of Freon gas started the period at around 150 thousand tonnes; despite a rapid rise in the first 5 years and reaching a high of 200 thousand tonnes, it underwent a substantial decrease for the rest of the given period, hitting a low of 20 thousand tonnes, becoming the smallest figure among the three types. In contrast, the production of NO2 and H2O2 gases grew marginally in the first decade from about 99 to approximately 110 thousand tonnes and from 0 to around 19 thousand tonnes, respectively. Both the figures continued to rocket to their peaks, with NO2 gas at nearly 140 thousand, which was the highest, and H2O2 gas at over 80 thousand square kilometres.
