Ozone hole goes large again
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.
