Antarctic Ozone Hole is Healing: Proof We Can Solve Environmental Problems

A new MIT-led study confirms the Antarctic ozone layer is healing, thanks to global efforts to reduce ozone-depleting substances. This is the first study to quantitatively show, with high confidence, that this recovery is primarily due to reduced emissions, not natural variability. Using a 'fingerprinting' method comparing simulations and satellite data, researchers identified a clear link between reduced emissions and ozone recovery. By around 2035, the ozone hole may even close completely in some years, offering compelling evidence that we can solve environmental problems.
