Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over Antarctica is one of the biggest on record. The hole, which is what scientists call an ‘ozone depleting area,’ reached a size of 26 million sq km on 16 September 2023. This is roughly three times the size of Brazil.
They don’t know why the ozone hole is big this year but they suspect it may be related to a volcanic eruption. Article concludes that scientists expect the ozone layer to be back to normal by 2050.
The suggestion is that this is an unusual year for the ozone layer which sees the hole expand this time every year before retracting again by December. They never suggest human behavior is damaging it again.
