Scientists recorded a total-column ozone concentration of 102 Dobson units, the 8th-lowest level since 1986.

If this new study is correct, the hole might not have been healing as much as we thought. In fact, the researchers say the depletion of the ozone in the layer above Antarctica could be driven by ...

After starting in late August, this year's ozone hole expanded to a peak of 8.49 million square miles (22 million square kilometres) by the end of September. This is over 1.16 million square miles ...

Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years; researchers believe chlorofluorocarbons (CFCs) aren't the only things to blame.

“The especially long-lived ozone holes during 2020-2022 fit squarely into this picture, as the size/depth of the hole during October was particularly notable in all three years.” ...

Instead this year’s ozone hole was about average size for the last 20 years, even a bit smaller than 2022’s, according to NASA and the National Oceanic and Atmospheric Administration. From ...

The ozone hole was at its biggest in 2000 at nearly 11.6 million square miles (29.9 million square kilometers), according to NASA data. But scientists say it will take decades to completely heal.

In 1987, several countries agreed to ban or phase down the use of more than 100 ozone-depleting chemicals that had caused a “hole” in the layer above Antarctica. The depletion is mainly ...
