Air pollution of the 21st century is a problem that involves a large number of chemical species and complex reactions between them. Both the public and politicians finds the science difficult to understand, and so, often mistrust the presentation of data and the scientific principles behind air quality. Yet, there are a range of important issues associated with air pollution that concern lay people and policy makers and hence, they have to be presented in a clear and simple way so that informed judgements can be made. Traditionally, the media was the main way to disseminate scientific discovery, but novel methods for engaging scientists in the transfer of scientific know-how to politicians and the general public have emerged in recent years. Scientists receive relatively little training in the area of communication, and often find engaging in more public debates difficult. These including V.I.P. meetings, Public Open Forum, Café Scientifique and various games and role plays. Such outreach events expose us to new challenges, and the skills required to communicate to non-scientists become an increasingly important part of being a scientist. © EDP Sciences.
