Key Takeaways:
- 1. The 2025 ozone hole over Antarctica was the fifth smallest since 1992.
- 2. Ozone-depleting chemical controls are driving the ozone layer’s gradual recovery.
- 3. The ozone hole is expected to recover fully later this century.
NASA and NOAA report that the 2025 Antarctic ozone hole was small compared to previous years, being the fifth smallest since 1992. The hole is breaking up earlier this year and is on track to recover fully later this century, thanks to controls on ozone-depleting chemicals. The ozone layer acts as a protective shield from harmful UV radiation. The decline in ozone-depleting substances indicates progress, with projections showing recovery by the late 2060s.
Insight: Factors like temperature, weather, and the strength of the polar vortex influence ozone levels annually. Monitoring is done using various instruments, and the latest data indicates a positive trend towards ozone layer recovery.
