Extreme weather events are slowing the recovery of the ozone layer, according to recent scientific reports.

What it means

This story from Scientific American reports that extreme weather events—such as heatwaves, wildfires, and storms—are now measurably slowing the recovery of the ozone layer. While international bans on ozone-depleting chemicals have allowed the ozone hole to begin healing, climate-driven weather extremes appear to be interfering with the atmospheric chemistry that sustains that recovery, potentially pushing back the timeline for full closure.

Accuracy & sourcesGrounded

The claim is based on synthesis of recent scientific reports, likely including WMO bulletins and peer-reviewed studies linking weather extremes to ozone chemistry, but no single primary study is explicitly cited in the headline or note. As an aggregated/secondary source with no direct primary attribution, the solidity is moderate—the underlying research is credible, but the article itself does not allow verification of specific findings.
