Kind: research · Impact: medium

## In brief

- The Antarctic ozone hole grew to the seventh-largest size on record in 2026.
- Unusual weather conditions pushed the hole close to its historic maximum.
- Scientists say international restrictions on ozone-destroying chemicals prevented even greater damage.

## Why it matters

The ozone hole's size is driven partly by weather, not only by chemical emissions, which matters for interpreting year-to-year ozone measurements. The source also indicates that existing chemical restrictions limited the damage.
