The ozone hole over the Antarctic has not only grown larger but also thinner throughout most of the spring.
Despite making a recovery in area and depth since the 2000s, the Antarctic ozone hole has been massive in the last four years.
There is much less ozone in the centre of the ozone hole compared to 19 years agoand may take longer to recover.
The hole averaged 23.1 million square kilometres, approximately the size of North America, making it the 16th largest over this period.
The Montreal Protocol on Ozone Depleting Substances quadrennial assessment report of 2022 confirmed the phase-out of nearly 99 per cent of banned ozone-depleting substances.
