Scientists from the Copernicus Atmosphere Monitoring Service (CAMS) have observed a reduction in the size of the ozone hole over Antarctica, suggesting a potential recovery after nearly 40 years since its alarming discovery in the 1980s. This year's ozone hole formed later and was significantly smaller than expected, indicating a positive trend. The ozone layer, essential for absorbing harmful UV radiation, poses risks to Antarctic wildlife, particularly seals and penguins, when the hole opens in spring. Experts warn that while these developments are promising, they are influenced by global weather patterns, and full recovery may take decades. Predictions indicate that the ozone layer could fully recover to 1980 levels by around 2066 over Antarctica. The Montreal Protocol, which successfully banned ozone-depleting substances, is credited as a key international effort in this recovery.
