The ozone layer is HEALING! Hole over Antarctica is smaller and started later than expected this year, promising study reveals

Daily Mail  

The ozone layer above the Antarctic may be healing at last, according to a promising new study. The 2024 Antarctic ozone hole was one of the smallest in recent years, formed later, and closed earlier Scientists have revealed some encouraging news for the planet as they find that the hole over the Antarctic is on its way to recovery following four years of worryingly large ozone holes The ozone layer is a thin layer of ozone gas – a molecule containing three oxygen atoms – that collects in Earth's upper atmosphere. This is over 1.16 million square miles smaller than the unusually large ozone hole which formed in early September 2022 As of early December, measurements show that the ozone hole above the Antarctic has fully closed What is the Polar Vortex? The last four years have been extremely late closures following an exceptionally short-lived hole in 2019 The variability is due to the changing strength and stability of the Polar Vortex which concentrates ozone depleting substances in the region above the South Pole where they produce the ozone hole During the southern winter, a large pillar of extremely cold, rotating air forms above the Antarctic. This year, however, two sudden atmospheric warming events in July disrupted the Polar Vortex and prevented the concentration of CFCs above the South Pole – leading to a smaller ozone hole.
