Social Vulnerability and Compound Heat-Flood Exposure in Houston, Miami, and Norfolk: A Census-Tract-Level Analysis

This study reveals that in Houston, Miami, and Norfolk, compound heat-flood exposure is disproportionately concentrated in socially vulnerable census tracts, with the strongest associations found in Miami and locally concentrated neighborhoods in Houston, indicating that these dual hazards track social inequality in an additive rather than multiplicative manner.

Comparative formation of disinfection byproducts and human health risk under different chlorinated disinfectant types and water matrices

This study comprehensively evaluates and compares the formation of disinfection byproducts and associated human health risks between conventional and cyanuric acid-stabilized chlorine disinfectants across tap and swimming pool water matrices, revealing that stabilized disinfectants generally yield lower carcinogenic risks while highlighting significant inhalation hazards from volatile compounds and current toxicological data gaps.

Fault-network topology and coupled controls of overpressure, hydrocarbon expulsion, and polygonal fault intensity on tight-oil accumulation in the Songliao Basin

This study characterizes the T2 polygonal fault network in the Songliao Basin's Sanzhao Sag and establishes a quantitative coupled threshold of overpressure, hydrocarbon expulsion intensity, and fault intensity that effectively predicts favorable tight-oil enrichment zones, revealing that fault intensity rather than connectivity is the primary control on hydrocarbon accumulation.

Power, Pollution and Policy: The Environmental and Community Costs of AI Data Centre Expansion

Using Virginia as a case study, this paper argues that the rapid expansion of AI data centers imposes severe environmental and community burdens that are obscured by inadequate efficiency metrics and weak regulatory frameworks, ultimately calling for enhanced transparency and enforceable policies to prevent the disproportionate shifting of costs onto local populations.

Delayed Southern Ocean heat release challenges climate stabilization policies

Using an Earth system model, this study reveals that even after achieving net-zero CO₂ emissions, abrupt deep convection in the Southern Ocean can release centuries of stored heat, causing a sudden global temperature rise that challenges the assumption that net-zero targets alone are sufficient for long-term climate stabilization.

Trade-driven diffusion of carbon dioxide removal exacerbates the decrease in global health co-benefits from the Paris Agreement

This study reveals that while international trade in carbon dioxide removal (CDR) generally exacerbates the loss of global health co-benefits by increasing fossil fuel use and raising opportunity costs, it can yield net health gains in specific biomass-abundant regions by reducing air pollutant emissions from forgone biomass decarbonization.

Hybrid Geothermal System Characterization of the Paipa–Iza Complex (Colombia) Using Analogue Comparison and Maturity Index Analysis

This study characterizes Colombia's Paipa–Iza Geothermal System as a structurally controlled hybrid reservoir sustained by felsic intrusions and evaluates its development potential using a newly introduced Geothermal Maturity Index, which classifies the resource as low-maturity with high exploration potential while identifying key barriers such as the need for advanced geophysical characterization and exploratory drilling.

Integrated Assessment of Water Quality and Heavy Metal Contamination in Water and Aquatic Biota of the Otomona River, Indonesia

This study assesses the water quality and heavy metal contamination in the Otomona River, Indonesia, finding generally good physicochemical conditions and compliance with standards for most parameters, though copper levels in water and lead levels in fish tissues exceeded permissible limits, with spatial modeling indicating increased metal concentrations toward the estuary.
