From the Center for Research on Environmental Decisions: The Psychology of Climate Change Communication. The subtitle reads:
A Guide for Scientists, Journalists, Educators, Political Aides, and the Interested Public
Currently reading it, but so far it sounds like good stuff. As summarized by Chris Mooney, the guide’s advice includes:
…knowing your audience, employing framing, using trusted messengers (often local voices), using the power of groupthink in your favor (rather than letting it turn against you), and much else.
I’ll probably yack more about this when I’ve finished it.
