The recovery of the ozone layer — which sits miles above the Earth and protects the planet from ultraviolet radiation — has been celebrated as one of the world’s greatest environmental achievements.

The Antarctic ozone hole in 2025 was one of the smallest in decades—a testament to the continuing success of international action to protect Earth's ozone layer, which shields us from the sun's ...

The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in Earth's protective layer of stratospheric ozone. Industrial chemicals known as chlorofluorocarbons (CFCs ...

A new study confirms the Antarctic ozone layer is healing as a direct result of global efforts to reduce ozone-depleting substances. A new MIT-led study confirms that the Antarctic ozone layer is ...

In one of the great environmental success stories of our time, scientists say that a 35-year-old agreement has resulted in the steady and promising recovery of the Earth's ozone layer, a critical ...

Learn about the ozone hole above Antarctica that is now confirmed to be shrinking due to reductions of harmful chlorofluorocarbons in the atmosphere. The ozone layer over Antarctica, damaged by air ...

At this time of year, as the sun rises over Antarctica, a “hole” opens up in Earth’s ozone layer. The ozone layer is a vital planetary boundary that protects all life on Earth from the sun’s damaging ...

Scientists discovered the ozone hole in 1985, but if they'd had the atmospheric monitoring capabilities of today, they could have found it 30 years earlier, according to new research. Reading time 3 ...

DENVER (AP) — Earth's protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says. A once-every ...

This year’s ozone hole over Antarctica ranked among the smallest since the early 1990s, reflecting steady progress from decades of global action under the Montreal Protocol. Declining chlorine levels ...
