The Antarctic ozone hole reached its largest size in a decade in 2026, covering 27.1 million square kilometers. This area is more than twice the size of the United States. Despite this, researchers indicate that the recovery of the ozone layer is ongoing, as the seasonal hole has been forming later in recent years. A strong polar vortex contributed to the current size, with weak atmospheric systems failing to disrupt it. The ozone layer is expected to recover at different rates, with full recovery projected by 2066 over Antarctica. International agreements have successfully phased out 99% of ozone-depleting substances, but their effects linger for decades.
