Antarctica's Ozone Hole Expands, Surpassing Brazil's Size

The ozone hole above Antarctica has grown to approximately 10 million square miles, making it one of the largest seasonal holes ever observed. The hole still experiences seasonal growth and shrinkage, but overall it is decreasing in size due to the Montreal Protocol and the decrease of ozone-depleting substances. The early start and rapid growth of the ozone hole this year may be attributed to the Hunga Tonga volcanic eruption in January 2022, which introduced large amounts of water vapor into the air. Scientists predict that the global ozone layer will return to its normal state by around 2050.

Ozone Hole Reaches Alarming Size Once More

Measurements from the Copernicus Sentinel-5P satellite reveal that this year's ozone hole over Antarctica is one of the largest on record, reaching a size of 26 million sq km on September 16, 2023. The size of the ozone hole fluctuates due to the strength of a wind band around the Antarctic area, and this year's unusual ozone patterns may be associated with the eruption of the Hunga Tonga-Hunga Ha'apai volcano in January 2022. The Montreal Protocol, which phased out the production and consumption of ozone-depleting substances, is expected to lead to the recovery of the ozone layer by around 2050.

"ESA Observes Alarming Expansion of Ozone Hole"

The ozone hole over Antarctica in 2023 is one of the largest on record, reaching a size of 26 million sq km, roughly three times the size of Brazil. The size of the ozone hole fluctuates based on temperature changes in the stratosphere, and this year's unusual ozone patterns may be associated with the eruption of the Hunga Tonga-Hunga Ha'apai volcano in January 2022. The ozone hole is largely determined by the strength of a wind band that flows around the Antarctic area, and the variability in size is influenced by the presence of chlorofluorocarbons (CFCs) and other ozone-depleting substances. The Montreal Protocol, implemented in 1987, aims to phase out the production and consumption of these harmful substances, leading to a predicted recovery of the ozone layer by around 2050.
