Good news! For the first time, direct satellite observations of the ozone hole over Antarctica have shown that levels of ozone-destroying chlorine are declining and the ozone hole is recovering. The decline in chlorine results from the Montreal Protocol, an international ban on chlorine-containing chemicals called chlorofluorocarbons (CFCs), released by human activity. This has resulted in about 20 percent less ozone depletion than there was in 2005 — the first year that measurements of chlorine

Each year, the hole in the ozone layer grows during Antarctic winter, reaching a maximum extent. In 2023, the ozone hole continued a trend of shrinking maximums, due to declining levels of ozone-depleting chemicals & weather in the Antarctic stratosphere. https://go.nasa.gov/3QHaWDp | NASA’s Goddard Space Flight Center

The ozone hole over Antarctica is slowly recovering, according to NASA & NOAA's long-term record. This year’s ozone hole was the 5th-smallest on record, reaching an annual maximum extent of 8.83 million square miles on Sept. 9, 2025. What we call the ozone hole is an annual thinning of Earth’s ozone layer over Antarctica every September. NASA and National Oceanic and Atmospheric Administration (NOAA) researchers monitor the growth and breakup of the ozone hole with instruments aboard the Aura, S

What's going on with the hole in the ozone layer? Thanks to a global effort to regulate ozone-depleting substances, the ozone hole is showing signs of recovery and is projected to return to a healthy level by mid-century. However, at NASA, scientists continue to monitor its progress. NASA’s Goddard Space Flight Center Qing Liang explains more.

Earth’s ozone layer protects us from harmful solar radiation. Human activity, including use of ozone depleting compounds like some refrigerants, led to the Antarctic ozone hole. The 1987 Montreal Protocol phased down these compounds, leading to an improved ozone layer. NASA scientists work with other researchers around the world to monitor the health of the ozone layer and the size of the Antarctic ozone hole. https://go.nasa.gov/3eojsC8 #OzoneDay | NASA’s Goddard Space Flight Center
