Should Health Professionals Speak Up to Reduce the Health Risks of Climate Change?

Should physicians take action in the political realm to address climate change? There are many historical examples of physician advocacy in the political sphere, both individually and as a collective, and many have argued that it is important for health professionals to advocate on a variety of issues. But which criteria should be used to determine when and how health professionals should take on particular advocacy issues, and is climate change an appropriate-or even obligatory-arena for physician advocacy? We propose a seven-part deliberative framework for making this determination.
