Antarctic Ozone Hole Reaches Seventh Largest Extent in 48 Years

NASA reports that the Antarctic ozone hole reached its maximum size on September 18, 2026, marking it as the seventh largest in 48 years of monitoring. While significant in area, it was not as deep as other large historical holes. The stratospheric ozone layer is vital for protecting Earth's life from harmful ultraviolet radiation, making its size a key environmental indicator.
