Ozone-Depleting Substances May Have Driven Arctic Warming, Study Finds

The world awakened to the hole in the ozone layer in 1985, which scientists attributed it to ozone-depleting substances. Two years later, in Montreal, the world agreed to ban the halogen compounds causing the massive hole over Antarctica. Research now shows that those chemicals didn't just cut a hole in the ozone layer, they also warmed up the Arctic. Now a new study has found that those ozone-depleting substances (ODS), which were developed in the 20s and 30s were responsible for roughly one-third of global warming from 1955 to 2005 and half of Arctic warming and sea-ice loss during that period. The study was published in the journal Nature Climate Change. Read more....
