Ozone Hole Shrinks: Recovery Trend Continues
The 2025 Antarctic ozone hole was notably small and short-lived, reinforcing a positive long-term trend towards the recovery of Earth's vital protective ozone layer, with its early closure on December 1 marking the fifth smallest observed since 1992. This encouraging development is a direct testament to the effectiveness of the Montreal Protocol, an international agreement that has systematically phased out ozone-depleting substances and is projected to lead to full Antarctic ozone recovery by around 2066.
