“It was meteorologically a very unusual year, and similar conditions might not happen again for 30 years,” Strahan said. “Also, chlorine levels are going down in the atmosphere because we’ve stopped producing a lot of CFCs as a result of the Montreal Protocol. If 30 years from now we had the same meteorological conditions again, there would actually be less chlorine in the atmosphere, so the ozone depletion probably wouldn’t be as severe.”
