What coverage agrees on
All three reports agree the Antarctic ozone hole grew quickly in early September 2026 and reached about 25 million square kilometres, above the seasonal average.

Antarctic ozone hole swells to 25 million square kilometres
CATCH ME UP
Copernicus reports the Antarctic ozone hole expanded rapidly in early September 2026 to about 25 million square kilometres.
That is about five million square kilometres above the historical average for this period.
The rapid growth is linked to sudden temperature drops and polar stratospheric cloud formation.
Other indicators, including the ozone column minimum and ozone mass deficit, remain close to average levels.
Why it mattersThe expanding ozone hole signals a larger exposure risk and tracks progress on ozone recovery.
AGREEMENT VS DISAGREEMENT
What lines up. What splits.
A quick read on shared facts, changing details, and different emphasis.
What is changing or disputed
Other ozone indicators are still near historical averages, so the overall assessment could shift if later measurements show a different trend.

Neutral3
The Antarctic ozone hole is described as having grown rapidly to about 25 million square kilometres in early September 2026. The reports say this is above the historical average, but not all related indicators changed in the same way. They note colder temperatures above the South Pole and polar stratospheric clouds as part of the explanation. One report quotes a director stressing the need to monitor the interaction between human-made disturbances and natural factors.

Antarctic ozone hole reaches 25 million km² as growth accelerates
Quick source take
The Copernicus Atmosphere Monitoring Service reports that the Antarctic ozone hole expanded rapidly in early September 2026, reaching approximately twenty-five million square kilometres. This area is about five million square kilometres above the historical average for this period. CAMS notes that while the hole has grown larger than usual due to sudden temperature drops and polar stratospheric cloud formation, other key indicators like the ozone column minimum and ozone mass deficit remain close to average levels.
Ozone hole reaches notable threshold early again as area increases above average in 2026: Copernicus
Quick source take
Copernicus reports that the 2026 Antarctic ozone hole has surpassed fifteen million square kilometres earlier than average and expanded to about twenty-five million square kilometres by mid-September. The publication highlights that while rapid growth is linked to colder stratospheric temperatures and polar clouds, other diagnostic indicators remain near historical averages. CAMS Director Laurence Rouil emphasizes the importance of monitoring the complicated interaction between human-made disturbances and natural factors.
Antarctic ozone hole expands above average in early September: EU climate agency
Quick source take
The EU climate agency reports that the Antarctic ozone hole expanded rapidly in early September to reach an estimated twenty-five million square kilometres, which is five million square kilometres above the seasonal average. Copernicus attributes this rapid development to a sudden drop in minimum temperatures above the South Pole, allowing the formation of polar stratospheric clouds. The report notes that despite the expanded area, other metrics such as the minimum ozone column value remain close to historical averages.
