The annual hole in Earth's ozone layer closed at the beginning of this month, scientists recently announced. This year's hole in the layer was smaller in 2024 than we’ve seen in any other year ...

The ozone layer above the Antarctic may be healing at last, according to a promising new study. The Copernicus Atmospheric Monitoring Service (CAMS) found that the hole above the South Pole closed ...

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 ...

Getty Images A Canadian scientist says he’s discovered a massive hole in the ozone layer over the tropical region of the planet that could impact 50 per cent of the world’s population.

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

At its worst in the late 1990s, about 10 per cent of the upper ozone layer was depleted, said Newman. Since 2000, it has increased by about 1 to 3 per cent per decade, the report said.

Hole in ozone is larger than ever and only getting bigger – and scientists don’t know why Ozone hole as of 2023 has surpassed its size of three years prior, scientists say ...

The report projects the Northern Hemisphere and a mid-latitude ozone could be completely repaired by 2030, but the Southern Hemisphere and polar regions could need an extra 20-30 more years.

Conclusive proof of a recovery in the ozone layer could be decades away, scientists say, and some areas, such as the area over the Canadian Arctic, are still at risk.

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 ...

Given that some ozone-depleting substances also function as greenhouse gases, their phaseout is an added bonus for the climate, it says, whilst stressing the need for continued monitoring and to avoid ...
