Interacting Effects of Sea‐Level Rise and Ocean Warming Reshape Thermal Environments on a Coral Reef

Abstract Sea‐level rise (SLR) alters nearshore hydrodynamics, yet its influence on coral reef thermal regimes under climate‐driven ocean warming remains poorly quantified. Using a fully coupled hydrodynamic–wave model validated at Palmyra Atoll, we isolate how SLR modifies temperature variability during a projected 2050 marine heatwave. Results show that while basin‐scale warming raises reef bottom temperatures broadly, SLR deepens shallow habitats and enhances tidal exchange, reducing daily and
