Ozone hole over Antarctica shrinks to its smallest since 2019 – scientists call it an "encouraging sign"

The ozone hole over Antarctica this year became the smallest and narrowest in the last six years, as reported by the Copernicus Atmosphere Monitoring Service. European scientists called this phenomenon an important sign of the ozone layer's recovery and the effectiveness of the global ban on ozone-depleting substances. This is reported by UNN.
