Tracking pH in real time to forecast abalone fishery risk
A 15-minute pH monitoring interval in a single Mexican fishing ground reveals what global models alone cannot: the bioeconomic future of pink abalone depends on local data. This study's integration of in situ sensors with Monte Carlo projections under IPCC scenarios is a measured, empirical approach to a pressing risk. By 2100, even moderate emission pathways could cut resource rent by thousands of dollars per boat annually.

Climate Change and Overfishing Threaten Caribbean Queen Conch Populations
The queen conch's decline is not a distant warning, it is a measurable reality. Overfishing has already pushed this keystone Caribbean species to Threatened status, yet climate impacts remain poorly understood. Our integrated models reveal stark divergence: benthic habitats may remain stable under optimistic scenarios, but surface-level projections warn of abrupt suitability losses across all pathways by 2040. Anticipating where suitable habitat persists is now essential for conservation.
Warming's Metabolic Stress Outweighs Acidification's Impact on Larval Survival
Larval survival in the dog conch falters most under extreme warming, not acidification alone. Our study shows that temperature, pH, and their interaction significantly reduce survival, with thermal stress overriding pH-dependent differences at 34 °C. Growth responds to pH, yet metabolism peaks under heat, revealing a physiological trade-off. These findings underscore that warming may become the dominant constraint on tropical marine larvae, reinforcing why integrated climate indicators, like those tracked in our 2025 Temperature Anomalies, matter for predicting coastal ecosystem vulnerability.
Long-Term Data Reveals Predictable Shifts in Coastal Water Quality.
Thirty-seven years of monthly data across 94 stations is a rare lens, and it shows that coastal water quality follows patterns we can actually anticipate. The study's strength lies in its chronological validation, which reveals that tree-based models hold up best for temperature and salinity, while chlorophyll-a remains stubbornly unpredictable. SHAP analysis adds a compelling layer, showing how predictor importance shifts with hydrography, particularly in the Pearl River-influenced west. This is a practical benchmark, not a theoretical one.
