Exceptional Heat Stress Drives Coral Bleaching Across Japan in 2024

The 2024 global bleaching event caused exceptional heat stress and widespread coral bleaching across Japan's entire latitudinal range from tropical Ryukyus to temperate Pacific coasts, driven by anomalous thermal anomalies that exceeded local baselines and reached Alert Level 3 severity.

Fragmented Corrections to the van Genuchten–Mualem Model Diverge by 24–68% from a Consistent Coupled Parameterization: A Quantitative Demonstration for Thermal, Osmotic, and Hysteretic Conditions

This paper demonstrates that the fragmented, inconsistent application of separate corrections for temperature, salinity, and hysteresis to the van Genuchten–Mualem model introduces significant quantitative errors (24–68%) in predicting soil water flow, and proposes a unified, closed-form parameterization that resolves these inconsistencies by rigorously coupling these factors without introducing new parameters.

Mangrove re-establishment links deep-soil carbon enrichment with greater microbial phosphorus acquisition after Spartina alterniflora control

This study demonstrates that re-establishing *Kandelia obovata* mangroves following *Spartina alterniflora* control enhances deep-soil organic carbon concentrations and shifts microbial resource allocation toward phosphorus acquisition, highlighting the importance of integrating depth-resolved carbon measurements with microbial nutrient indicators in post-control assessments.

Unveiling the Human-Climate Nexus through the CLIMAgenAI framework: a Multi-Source Causal Framework for Climate Risk Analysis and AI-Supported Disaster Governance

This paper introduces CLIMAgenAI, a multi-source causal framework that integrates judicial, archival, and multimedia evidence into a unified representation of climate-related disasters to support AI-driven risk analysis and governance, as demonstrated through the reconstruction of the 1998 Sarno debris-flow event.

A UV–Comfort Co-occurrence Index reveals erythemal exposure opportunity on the South Atlantic coast

This study introduces a UV–Comfort Co-occurrence Index (IVCC) for Argentina's South Atlantic coast, demonstrating that thermal comfort, rather than UV irradiance alone, governs the timing and spatial distribution of human exposure opportunities, with late morning emerging as the critical window when high UV hazard coincides with thermally comfortable conditions.

Divergent rainfall delivery, runoff response, and retained-material composition across contrasting Andean coffee systems

This study demonstrates that in Andean coffee agroforestry systems, canopy-mediated rainfall interception significantly reduces soil water delivery and alters the composition of retained materials, indicating that lower absolute runoff in shaded systems reflects reduced rainfall input rather than superior surface water regulation.

Soil Pb and Cd accumulation and age-dependent biochemical responses in Crocodylus moreletii: Evidence of chronic contamination in a protected urban lagoon

This study demonstrates that chronic lead and cadmium contamination in the urban Laguna de las Ilusions lagoon is associated with significant, age-dependent alterations in biochemical biomarkers of wild *Crocodylus moreletii*, highlighting the species' utility as a sentinel for monitoring environmental stress in tropical urban wetlands.

Long term assessment of Saharan Dust Events in the Eastern Mediterranean by Optical and Microphysical Aerosol Metrics

This study demonstrates that combining optical and microphysical aerosol metrics, particularly a coarse-to-total volume ratio threshold greater than 0.70, significantly improves the reliable detection of Saharan dust events in the polluted urban environment of Athens, Greece, by effectively distinguishing natural dust from anthropogenic fine-mode aerosols.
