The ozone layer over Antarctica, damaged by air pollution decades ago, has fortunately been recovering in recent years. Scientists have observed gradual ozone restoration since the 2000s, but now, one study all but confirms that this positive trend is a result of reduced ozone-depleting chemicals in the atmosphere.
The study, recently published in Nature, reveals a bright spot in the current climate outlook. Testing simulations based on different climate factors, researchers seemingly confirmed that efforts to limit the emission of chlorofluorocarbons (CFCs) — chemicals that contain carbon, chlorine, and fluorine — are the main reason why ozone recovery is seeing continuous success.
