On September 16, 2023, the 'ozone depletion area,' as scientists refer to the hole, grew to a size of 26 million square kilometers, around three times that of the small nation of Brazil.

The existence of the Antarctic ozone hole was first discovered in the 1980s when scientists observed a rapid and dramatic decline in ozone concentrations over Antarctica during the spring months. An international agreement called the Montreal Protocol was adopted in 1987 and aims to gradually phase out the manufacturing and consumption of ODS. Recent reports revealed that the ozone layer was progressively recovering as a result of its tremendous effectiveness in lowering ODS emissions.However, new data is not so positive. ESA claims that the strength of a powerful wind band that circles the Antarctic region greatly influences the variability of the ozone hole's size.
