Climate change has a major impact on public health, especially for vulnerable communities. Rising temperatures, severe storms and other severe events can negatively affect health outcomes. Agencies are increasingly using data and technology for programs and tools to boost health equity. Dr. John Balbus, director of the Office of Climate Change and Health Equity at the Department of Health and Human Services, speaks about the ways that technology can be used to build resilience against climate-related negative health outcomes. He discusses his career, his role in shaping policies and his agency’s Health Climate Outlook tool for predicting climate-related health risks.
