NOAA attributed the improvement to declines in ozone-depleting chemicals. Scientists said the ozone layer could fully recover by 2066.

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

Asian Monsoon Lofts Ozone-Depleting Substances to Stratosphere Apr. 23, 2024 — Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone ...

In 2024, the ozone hole over the Antarctic showed a notable reduction in size, ranking as the seventh smallest since monitoring began post-Montreal Protocol. This improvement is credited to ongoing ...

In fact, the ozone hole ranked the seventh smallest since it began recovering in 1992. NOAA said the improvement is due to declines in ozone-depleting chemicals.

The ozone hole reached its maximum extent of 22.4 million square kilometers (8.5 million square miles) on September 28, marking what researchers describe as a relatively small depletion compared ...

Each year, a combination of ozone-depleting chemicals and cold temperatures combine to open the annual ozone layer hole above the Antarctic. While this hole still allows harmful ultraviolet ...

the size of this year's ozone hole can only partly be attributed to the reductions in ozone-depleting chlorofluorocarbons (CFCs). CFCs were primarily used in aerosol cans and refrigeration and ...

It provides information on emissions of ozone depleting substances (ODS) in Australia and globally. The report summarises measurements of ODSs observed at Cape Grim in Tasmania up to 2023. The import ...
