Cities and their geographies are key templates for developing mitigation strategies to address climate-related health impacts globally. Yet effectively communicating climate-related health risks to vulnerable communities remains crucial particularly in emerging cities where proactive urban planning can help reduce climate-related health problems. Given the complexity of climate change information and academic jargon in scientific findings including climate reports by the Intergovernmental Panel on Climate Change (IPCC), this study examines existing communication barriers that limit community’s understanding, attitude and response to climate change impacts on health. It also identifies the communication tools that best disseminate climate-related health risks on a more personal level. The study adopted a qualitative research method using two (2) purposively designed semi-structured questionnaires, one for children/adolescent and one for adults and the elderly. These were administered to 150 respondents randomly selected in an emerging city in South Western Nigeria. The study’s findings provide useful insight that can improve how climate-related health threats and mitigating policies are communicated, understood and addressed by residents and ultimately reduce population health risks associated with climate change. The study concludes that effective risk communication can influence positive response to government-led climate-related health initiatives, and build resilient communities.
