Projections provided by the Intergovernmental Panel on Climate Change, and key messages for Hawai‘i and other Pacific islands from the National Climate Assessment, indicate sea-level rise will bring about more frequent and extreme tidal flooding and inundation by tidally influenced coastal groundwater. The University of Hawai'i Sea Grant College Program is engaging citizen scientists to document today's high water level events, (commonly referred to as “King Tides”) to better understand tomorrow's impacts from sea-level rise and other coastal high water events. These photographic data are entered into a publicly available dataset and online interactive map, and are informing research, policy, and decision making across the State of Hawai’i and Pacific region. First-person experiences/visuals that are place-based and familiar reinforce that climate impacts are local in nature and not a distant phenomenon.

Attendees will learn about the phenomenon of King Tides, methods of data collection, and how to participate in the program. Additionally, there will be an opportunity to assist the program with feedback and insights into usage of the data and implications for current and long-range planning.
