Climate Change

Rising temperatures, changing weather patterns, and other effects of climate change are placing human health at risk. Increasing threats to health include worsening air and water quality, increased exposure to vector-borne and infectious diseases, threats to food security, and increased mental health and stress-related disorders. Climate change exacerbates not only health and environmental concerns, but also social inequities. The impacts to health burden certain populations disproportionately, including but not limited to, communities of color, immigrant populations, tribal communities, children and older adults, people with disabilities or health conditions, low-income communities, and pregnant people.

As communities across the United States are faced with the health and societal effects of climate change, local health departments are uniquely positioned to identify, prevent, and respond to climate-related health impacts in an equitable manner. NACCHO aims to provide resources to ensure local health departments are equipped to take on this role, while elevating best practices and success stories at the local level.

The NACCHO Global Climate Change Workgroup is committed to providing leadership and resources to support local health department climate change efforts. The workgroup is comprised of local health officials, environmental health professionals, environmental health directors, and subject matter experts who are interested in enhancing climate change adaptation and mitigation policies and practices.

The workgroup holds at least one in-person meeting (pending funding), monthly conference calls, and work in between meetings. In addition, the workgroup reviews documents and participates in judging model practice applications throughout the year. Appointment to the workgroup is for a two-year term with an option for reappointment to a second two-year term. Message for more information.
