Global coral reefs marine heatwave induced thermal stress database (1982-2024)

This publicly released dataset provides a global assessment of marine heatwave-induced coral reef thermal stress metrics at the reef-pixel scale (~25 km) from 1982 to 2024. It improves understanding of how climate change affects coral reef ecosystems by characterizing marine heatwaves and related thermal stress across more than four decades. Jupyter notebooks and data to reproduce the figures in the submitted manuscript "Global Coral Reef Thermal Stress: Patterns, Trends, and Emerging Regimes" in the Environmental Research Letters by Busireddy et al. (2025) are provided here.
