Ozone hole lingering on top Antarctica

With an unseasonably warm spring on the cards in Australia, atmospheric scientists are casting their eyes to the ozone hole lingering above Antarctica. Unusual events in recent years have delayed the recovery of the ozone hole, which was first discovered in 1985. Some of these events include the Australian bush fires of 2019 to 2020 and rocket launches. Laura Revell is an associate professor in environmental physics at the University of Canterbury and says full recovery will take some time.
