Credit for the surprisingly good air quality at the 2008 Beijing Olympics has been given to the Chinese government for various steps taken to reduce pollution sources, especially vehicle emissions, during and before the games- as they had been, with equally good health results, at the Atlanta, USA Games in 1996. A more detailed analysis of the added effect of meteorology, summarized in the article under review, shows that favourable winds and well-timed rainfall had at least as much to do with the  results. The lesson to be learned from this, especially for those cities with unhealthy air, with or without Olympic fever, is that major reductions in pollution and improvements in health are possible with enough government will to engage public support.
