The ozone hole over Antarctica is the seventh smallest it’s been since the early 1990s. Recovery began with the Montreal Protocol, which ended the production of all chlorofluorocarbons (CFCs) in 1987.

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 ...

While continental in scale, the ozone hole over the Antarctic was small in 2025 compared to previous years and remains on track to recover later this century, NASA and the National Oceanic and ...

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 ...

Oct. 30 (UPI) --A hole in the atmosphere's ozone layer is the seventh-smallest since recovery began in 1992, the National Oceanic and Atmospheric Administration announced Wednesday. The hole annually ...

A hole in the Montreal Protocol could delay the recovery of Earth’s ozone layer by about 7 years. New research found that the ...

This map shows the size and shape of the ozone hole over the South Pole on Sept. 28, 2024, the day of its annual maximum extent, as calculated by the NASA Ozone Watch team. Scientists describe the ...

A new MIT-led study confirms that the Antarctic ozone layer is healing, as a direct result of global efforts to reduce ozone-depleting substances. Scientists including the MIT team have observed signs ...

Remember the hole in the ozone? (TIME magazine does.) Thanks largely to the unchecked use of chemicals like chlorofluorocarbons (CFCs) and halons in the postwar era, the ozone layer thinned ...
