Turning the corner

The Antarctic ozone hole is finally showing signs of disappearing, nearly 30 years after the Montreal Protocol came into effect. The Montreal Protocol, an international treaty that phased out the production of many of the human-made compounds responsible for stratospheric ozone destruction, is widely considered to be the most important and successful international environmental agreement. For years, it has slowed the rate of stratospheric ozone depletion, and now there are signs that the ozone abundance over Antarctica has begun to increase. Solomon et al. present observational data and model results to illustrate the trends and diagnose their causes.
