The ozone layer sits toward the bottom of the stratosphere, roughly 20 to 40 kilometers (66,000 and 131,000 feet) above the ground.

The ozone layer is on track to recover to 1980 levels by 2040, a new U.N. report assessing the progress of the Montreal Protocol found.

Ozone just adds another atom. The beneficial ozone layer, located high up above the ground in the stratosphere, is the feature that keeps all of us from burning to a crisp.

At its largest point this year the ozone layer hole was 8.5 million square miles (22.4 million square kilometres) on September 28. This is 1.5 million square miles smaller than the peak size in 2023 ...

Synthetic chemicals like the chlorofluorocarbons (CFCs), used to make aerosol sprays, solvents, and refrigerants can destroy ozone, and caused Earth’s ozone layer to deplete during the 20th century.

Without an adequate ozone layer, life cannot sustain itself on Earth. For that reason — and despite protests from businesses that profited from manufacturing and using CFCs — the international ...

That ban, agreed under the Montreal Protocol, is widely considered to have been effective in aiding the ozone layer’s recovery. But the hole, which grows over the Antarctic during spring before ...

The healing ozone layer offers hope for the fight against climate change. But only to an extent. Because curbing greenhouse gas emissions is a much more encompassing task, requiring us to wholly ...

This study upends how we think about the ozone layer and our health The ozone layer’s effect on our lives may be more complicated than it seems September 22, 2023 7 min ...

In rare good news for the planet, the hole in the Earth’s ozone layer is on track to recover completely within decades as harmfule chemicals are phased out, according to a new UN-backed assessment.

Ozone layer is slowly healing, with the hole to be mended by 2066, U.N. says In this NASA image, the blue and purple show the hole in the ozone layer over Antarctica on Oct. 5, 2022.
