Antarctic Ozone Hole Smallest in 6 Years, Signals Earth's Slow Recovery

• The Antarctic ozone hole has shrunk to its smallest size in six years, indicating a slow but steady recovery of Earth's protective ozone layer.
• In 2025, the ozone hole averaged 7.23 million square miles during its peak depletion period, making it the fifth-smallest since 1992.
• A weaker polar vortex and higher August temperatures contributed to the shrinkage, allowing more ozone-rich air to enter the region.
• The Montreal Protocol, a 1987 global agreement to phase out ozone-depleting chemicals like CFCs, is credited with driving this recovery.
• Scientists predict that if current policies continue, the Antarctic ozone layer could return to 1980 levels by 2066.
