Evidence-based communication on climate change and health: Testing videos, text, and maps on climate change and Lyme disease in Manitoba, Canada

change communication and associated development of CIWs, with a strong, continuous feed- back cycle between developers/users and theory/practice. This paper demonstrates that a con- tinuum of climate communication materials–from video, text to maps–may increase salience and emotional response with each subsequent intervention. Indeed, it is paramount that cli- mate communicators evaluate, interrogate, and revise their approaches and tools to ensure information is appropriate for different audiences and their concomitant worldviews. By tak- ing this type of evidence-based approach, climate communicators and CIW developers will ideally increase both climate knowledge and action across various audiences within society.
