The effective communication of the severity and impacts of climate change to the general, non-scientific public is necessary to enable public support for widespread mitigation and adaptation actions. Submissions are welcomed that describe strategies and practices used within the community to communicate climate change risk, including but not limited to: the quantification of climate change impacts on individuals or communities; descriptions of the impacts of specific climate perils including flood, wildfire, heat, drought, sea level rise, hurricanes and convective storms; the quantification of climate change’s effects on our economy and society; the integration of climate change information into decision-making processes in governments, businesses, and communities; and novel ways of the reduction of complex climate change science data to easily-understandable and actionable information. Submissions are welcomed from scientists, policy-makers, educators, businesses, nonprofits, government agencies, and communication professionals. We wish to highlight those strategies and practices that have demonstrated their effectiveness through evidence-building and sustained public engagement.
