This two-page brief from the NOAA (National Oceanic and Atmospheric Administration) Coastal Services Center addresses risk behavior and communication and lays out some best practices for communicating risk and changing public behavior. "Human exposure to risk from coastal hazards is increasing because vulnerable coastal areas are becoming more densely populated. Coastal hazards such as hurricanes and floods are predicted to become more intense as a result of climate change. Better risk communication can save lives, protect property, lessen damage to coastal economies, and create more resilient coastal communities that recover more quickly after a disaster."
