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 ...

Around the turn of the 21st century, much of the environmental conversation was about the hole in the ozone layer. There was an understandable panic after it was discovered in the 1980s that ...

The ozone hole was first observed in the early 1980s and reached its largest extent in 2006, according to NASA. This year's ozone hole, which peaked on Oct. 5, was the biggest recorded since 2015.

In a paper, published by Nature Communications, they found that ozone levels have reduced by 26% since 2004 at the core of the hole in the Antarctic springtime.

The hole was traced back to certain gases—ozone-depleting chlorofluorocarbons (CFCs)—that were widely used in the 1980s, particularly in fridges, air conditioners, and similar pieces of equipment.

It's been 35 years since the Montreal Protocol helped heal a hole in the ozone. Can those lessons curb climate change in less than 30 years?

This year’s ozone hole is expected to close in a few days, according to scientists. In 2021, the hole lasted until Dec. 23. The longest ozone hole season on record happened in 2020 when it didn ...

But now, in an 'awesome' turnaround, the ozone hole is actually healing, experts have found. And, if the trend continues, it could eventually stay shut for good, they said.
