In 2025, the ozone hole reached one of its smallest recorded sizes in recent decades.

What it means

The 2025 Antarctic ozone hole was one of the smallest and shortest-lived in decades, ranking as the 5th smallest since 1992 according to NASA and NOAA. This reflects the ongoing recovery of the ozone layer, driven by the global phase-out of ozone-depleting substances under the Montreal Protocol, and supports projections that the ozone layer will fully recover later this century.

Accuracy & sourcesGrounded

The claim is solid, based on official monitoring by NASA, NOAA, and the World Meteorological Organization, which reported the 2025 ozone hole's small size and early closure. The Phys.org article is a reputable secondary source closely aligned with these primary data releases, and the finding is corroborated by multiple independent space agencies.
