![Photo: Since 2013, annual emissions of a banned, ozone-depleting chlorofluorocarbon (CFC) have increased by nearly 8,000 tons from eastern China. That year South Korea's Gosan GAW Regional Station, on the southwestern tip of Jeju Island, started detecting spikes in CFC-11 levels drifting in from eastern Asia.
