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

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 ozone hole was healing, or at least that’s what scientists told us. Managing to undo the damage that greenhouse gas emissions have done has been heralded as one of the world’s greatest ...

From September to mid October, the ozone hole this year averaged 8.9 million square miles (23.1 million square kilometers), which is the 16th largest since satellites started tracking in 1979.

The peak size of the ozone hole over the Antarctic in 2024 was the seventh smallest since recovery began, NASA and the National Oceanic and Atmospheric Administration (NOAA) have found. Even its ...

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.

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 ...

With last year’s undersea volcano injecting massive amounts of water high into the atmosphere, scientists were bracing for a big Antarctica ozone hole this fall. But it didn’t happen. Instead ...
