Ozone hole continues to slowly recover, thanks to an international agreement to ban ozone-depleting substances.

It should close later this century.

NASA, NOAA Rank 2025 Ozone Hole as 5th Smallest Since 1992

The ozone hole over the Antarctic was small in 2025 compared to previous years and remains on track to recover later this century. The hole this year was the fifth smallest since 1992, the year a landmark international agreement to phase out ozone-depleting chemicals began to take effect.

Ballan, suspendu deux ans, se défend: «De l'ozonethérapie, pas du dopage"

L'ancien champion du monde de cyclisme, l'Italien Alessandro Ballan encourt une suspension de deux ans. Telle est la sanction qui a été requise jeudi par le Comité olympique italien (CONI). Celui-ci soupçonne le coureur de la BMC de s'être dopé en 2009 alors qu'il portait le maillot de l'équipe Lampre.

“In general, from 2020 onward, a strong rise in space waste mass influx to the #atmosphere can be seen. ... This indicates a substantial risk of long-term adverse effects on the atmosphere such as #ozone depletion, radiative effects and changes in #cloud formation, if no action is taken. Research is urgently needed into the atmospheric accumulation, #chemistry, and general atmospheric effects of specific elements.”
