University of Miami Rosenstiel School AI Predicts Coral Bleaching Risk Up to 6 Weeks Out
Summarize this article with:
Scientists at the University of Miami Rosenstiel School have developed an artificial intelligence model capable of forecasting coral bleaching risk along Florida’s Coral Reef up to six weeks in advance. The groundbreaking system, detailed in a study published December 16, 2025, provides site-specific predictions accurate to within one week, offering crucial time for intervention. “This model gives coral scientists and resource managers advance notice of whether heat stress is likely to occur in a season—and, more importantly, the week it is most likely to begin,” explains lead author Marybeth Arcodia of the Rosenstiel School. By combining atmospheric science, coral ecology, and data spanning from 1985–2024, the AI offers actionable insights to proactively combat the increasingly frequent and severe bleaching events impacting vital reef ecosystems. XGBoost Model Forecasts Coral Heat Stress Up To Six Weeks The system’s performance surpassed both multiple logistic regression and frequency-based prediction methods in both identifying heat stress occurrence and pinpointing its onset. “Our prediction system produced skillful forecasts up to six weeks in advance, and in most cases it was accurate to within about one week of when heat stress actually began,” said Richard Karp, a co-author and post-doctoral research associate. Utilizing explainable AI techniques, specifically SHAP, the model also reveals the environmental factors driving these predictions at each site, allowing managers to identify critical trigger points for emergency action plans, as “This information gives managers an opportunity to identify trigger points in emergency action plans, which can support planning and response decisions,” according to Karp. SHAP Analysis Reveals Key Environmental Stress Drivers Scientists have moved beyond simply forecasting coral heat stress to understanding why it occurs at specific locations, leveraging a new AI model and SHAP analysis. The research team, working with data from 1985–2024, built a prediction tool focused on Florida’s Coral Reef, incorporating atmospheric science, coral ecology, and data science. This system forecasts the onset of moderate heat stress—a key precursor to coral bleaching—up to six weeks in advance, with accuracy generally within one week. The innovation lies in the application of SHAP, which reveals which environmental factors most strongly influence each prediction, varying by reef site and forecast lead time. Surface air temperature consistently emerged as a critical predictor, but other key factors shifted, highlighting the need for localized forecasting. This model gives coral scientists and resource managers advance notice of whether heat stress is likely to occur in a season – and, more importantly, the week it is most likely to begin. Localized AI Complements NOAA Reef Monitoring Systems This new system isn’t designed to replace existing NOAA Coral Reef Watch tools, but rather to complement them by providing a localized, seasonal signal for predicting heat-stress onset.
The team utilized an XGBoost machine-learning model, analyzing environmental data from 1985–2024, including sea-surface temperature anomalies, air temperature, and indicators of Loop Current and El Niño conditions.
