Sea level rise in Maui, Hawaii, refers to the increasing height of ocean levels due to climate change, primarily driven by melting ice caps and thermal expansion of seawater, with local factors like land subsidence contributing. Since 1950, sea levels around Hawaii have risen about 10 inches, and projections suggest a rise of up to 3.2 feet by 2100. Funding for sea level rise research and adaptation in Hawaii comes from federal agencies like NOAA, state resources through the Department of Land and Natural Resources, and academic institutions like the University of Hawaii’s Sea Grant Program. The purpose is to assess vulnerabilities, inform coastal management, and protect infrastructure, ecosystems, and communities, with tools like the Hawaii Sea Level Rise Viewer aiding planning. Accuracy depends on modeling, which integrates historical data, wave buoy measurements, and LiDAR-based topography, but uncertainties remain due to variable climate scenarios and local conditions; models are refined to within 5-meter grids, though thin water layers (<10 cm) are excluded to avoid overstating impacts. For Maui’s real estate, a 2021 law mandates sellers disclose sea level rise risks for properties in the 3.2-foot Sea Level Rise Exposure Area, impacting coastal property values (e.g., 9-14% price declines on Oahu for exposed properties) and buyer decisions, though demand for oceanfront homes remains strong despite sea level rise.
