The complexity and politicization of climate computer models can hinder communication of their science, uses and limitations. Evidence suggests that information on climate models in US newspapers is declining and that when it appears, it is often within sceptic discourses. Furthermore, model projections are frequently portrayed as probably being inaccurate, and political opinion outlets provide more explanation of model results than many news sources.

The problem isn’t the public’s reasoning capacity; it’s the polluted science-communication environment that drives people apart, says Dan Kahan.

“Science-based” standards are an integral part of modern regulatory systems. Studies on “public understanding of science” mostly focus on high technology areas in advanced economies. In contrast, the present study analyses the public understanding of regulation in the context of standard-setting for bottled water quality in India. Using primary data, the econometric models of this paper show that public understanding of participation in regulation depends on awareness of, and trust in, existing regulatory practices in a complex, non-linear manner.

Promotion of physical activity is a priority for health agencies. We searched for reviews of physical activity interventions, published between 2000 and 2011, and identified effective, promising, or emerging interventions from around the world. The informational approaches of community-wide and mass media campaigns, and short physical activity messages targeting key community sites are recommended.

When reporters aren’t given the facts, they are likely to jump to the most extreme conclusions, says David Brown.
