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 Antarctic witnessed a significant increase over the years. Additionally, while the production of Freon gas recorded a remarkable decline over the period, those of 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 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 square kilometres; despite a rapid rise in the first 5 years and reaching a high of 200 thousand square kilometres, it underwent a substantial decrease for the rest of the given time, hitting its low of 20 thousand square kilometres, 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 square kilometres and from 0 to around 19 thousand square kilometres, respectively. Both the figures continued to rocket to its peak at nearly 140, which was the highest, and over 80 thousand square kilometres.
