Ozone Layer Healing: Antarctic Hole Shrinks as Scientists Predict Closure
Ozone Layer Shows Signs of Recovery It has been four decades since scientists first identified the growing hole in Earth's ozone layer. However, a recent study brings encouraging news: this protective shield, located approximately 20 miles above the planet’s surface, may be on the path to recovery. Experts from the World Meteorological Organisation (WMO) have noted that, compared to previous years, the total stratospheric ozone cover was higher across much of the globe in 2024. This is especially evident in the ozone hole that typically forms over Antarctica each spring, which was well below the 1990–2020 average. Antonio Guterres, the United Nations Secretary-General, remarked, “The ozone layer is healing. This achievement reminds us that when nations heed the warnings of science, progress is possible.” If the current pace of improvement continues, the ozone layer could soon return to its 1980 levels—before the appearance of the ozone hole. Experts predict that full recovery mi...
