The Ozone Layer Is Quietly Healing Itself
On track for full recovery: ~2040 (rest of world), ~2066 (Antarctic)
Every four years, UN-backed scientists audit the atmosphere: the 2022 Scientific Assessment of Ozone Depletion confirmed the Montreal Protocol is working, with ozone heading back toward 1980 benchmarks on predictable timelines. NASA's satellite record shows the same healing trend. A global environmental problem actually getting fixed — because every country on Earth signed one treaty.
The ozone hole is shrinking and UN scientists say the ozone layer is on track to fully recover — Antarctic around 2066, the rest of the world closer to 2040.
