Research shows Antarctic ozone hole getting deeper in mid-spring

Despite a global ban on ozone-depleting chemicals, the hole in the Antarctic ozone layer has deepened during mid-spring over the past two decades, according to research. The 1987 Montreal Protocol, which banned chlorofluorocarbons (CFCs), was expected to lead to the recovery of the ozone layer by 2066. However, a study by New Zealand researchers found that, despite the decline in CFCs, the Antarctic ozone hole’s area has not significantly reduced, and there has been less ozone at its center over time. The researchers suggest that other atmospheric factors, possibly related to climate change, may be hindering recovery.
