Antarctic Ozone Hole Reaches Seventh-Largest Size in 2026

The Antarctic ozone hole expanded to its seventh-largest size on record in 2026, according to NASA and NOAA. This expansion was primarily due to unusual weather conditions and a strong polar vortex. Despite this year's increase, scientists affirm that international restrictions on ozone-depleting chemicals continue to support the ozone layer's gradual recovery, preventing even more severe damage over time.
