The ozone hole over Antarctica expanded in 2026 to its largest area in a decade, peaking at 10.5 million square miles on September 18—the seventh-largest hole in 48 years of observations. Researchers attributed this to an unusually strong polar vortex, but said limits on ozone-depleting substances kept the hole from growing by another one to two million square miles. Scientists expect the ozone layer to recover by the 2070s as these compounds gradually disappear.
