The 2023 ozone hole opened early and fast, becoming one of the largest on record in mid-September, and it’s one of the longest-lived observed to date. The causes of this behaviour point to climate change or volcanic emissions.
A large hole in the Antarctic ozone layer once thought to be steadily closing could actually be widening, according to new research.
The Ozone hole over the Antarctica continent has become unprecedentedly deeper and larger in the last 15 years, the latest finding of the World Meteorological Organization has shown. It has reached its peak of at 24 mil square km.
Scientists at MIT and elsewhere have identified the "first fingerprints of healing" of the Antarctic ozone layer, published today in the journal Science. September ozone hole has shrunk by 4 million square kilometers since 2000.
