Coral reefs are highly productive ecosystems that provide valuable services to coastal communities worldwide. However, both local and global anthropogenic stressors, threaten the coral-algal symbiosis enables reef formation. This breakdown of symbiotic relationship, known as bleaching, is often triggered by cumulative cell damage. UV heat stress commonly implicated in but other factors may also play a role. To address coral loss, active restoration already underway many critical regions. Additionally, researchers exploring assisted evolution methods for greater resilience projected climate change. review provides an overview mechanisms underlying bleaching response strategies being pursued loss. Despite necessity ongoing research all aspects this field, action on change remains crucial long-term survival reefs.

This study introduces a combined Marine Heatwaves-Degree Heating Weeks (MHW-DHW) analysis to evaluate climate change impacts on three coral refugia: Green Island, Nanwan Bay, and Dongsha Atoll. MHWs reflect rapid rises in Sea Surface Temperature (SST) their timing, while DHW captures sustained high SSTs, indicating thermal stress, potential bleaching risks, vulnerability of habitats. Since 2016, MHW development has significantly increased annual stress. Between 2020 2022, nearly half each year they faced threats corresponding Bleaching Alert Levels 2 3. Historically, events were linked strong El Niño transitioning La Niña conditions during the negative phase Pacific Decadal Oscillation; however, recent global ocean warming masked this pattern. Periodic cooling due upwelling these habitats is not fully captured by CoralTemp dataset smoothing low spatial resolution. SST values differ from Himawari satellite observations about 1 1.4 °C daily minima, leading average discrepancies 0.2–0.5 °C. suggests diurnal temperature variations may still mitigate temperatures. Furthermore, multi-satellite data revealed that affected chlorophyll concentrations within
