The Science Behind Ozone Layer RecoveryThe ozone layer, a critical part of the stratosphere located between 15 and 30 kilometers above Earth, acts as an invisible shield protecting life from harmful ultraviolet radiation. Satellite data showing total ozone anomaly shows the year-to-year variability of the ozone layer. “Today, the ozone layer is healing. If current policies continue, projections suggest that the ozone layer will fully recover by 2066 over Antarctica, 2045 over the Arctic, and 2040 globally. As the ozone layer continues its recovery, the achievement serves as a blueprint for future environmental action.
