Climate overshoot and irreversibility: Implications for the social cost of greenhouse gases and emission metrics

This study demonstrates that accounting for irreversible climate damages in temperature overshoot pathways significantly increases the social cost of methane and contrail cirrus relative to carbon dioxide before peak warming, thereby challenging conventional emission metrics while lowering post-peak cost estimates due to locked-in damages.

The acoustic environment is a property of place and fine particulate matter a property of time: co-located measurements across Providence, Rhode Island

This study demonstrates that in Providence, Rhode Island, the acoustic environment is primarily determined by static place-based factors like land use and tree canopy, whereas fine particulate matter (PM2.5) is driven by dynamic temporal factors like weather conditions, indicating that these two pollutants should be assessed separately rather than combined into a single environmental quality index.

MTA-Net for Predicting Grain-Size Composition Distributions from Sedimentary Simulation Experiment Images by Integrating Multiscale Texture Features

This paper introduces MTA-Net, a deep learning model that integrates ResNet34 with Horizontal Multi-Scale Local Binary Pattern (HMS-LBP) and Convolutional Block Attention Module (CBAM) to accurately predict grain-size composition distributions from sedimentary experiment images by effectively capturing multiscale texture features and overcoming challenges like particle overlap.

Spatio-temporal Dynamics of Physico-Chemical Hydrology and Aquatic Insect Assemblages in a Western Nigerian River: A Canonical Correspondence Approach to Ecological Integrity

This study utilized Canonical Correspondence Analysis to reveal that hydromorphological attributes, rather than nutrient gradients, primarily structure aquatic insect assemblages in Western Nigeria's Omi River, which maintains high biological integrity despite significant seasonal fluctuations driven by the tropical climate.

Validation of a Modified Normalized Particle Swarm Optimization Model for Characterizing Pore Structure in Permo–Triassic Khuff Carbonate Reservoirs, Central Saudi Arabia

This study validates a modified normalized particle swarm optimization (MNPSO) model as a robust and reliable tool for characterizing pore-structure heterogeneity in Khuff carbonate reservoirs, demonstrating its strong correlation with permeability and excellent agreement with conventional fractal methods.

Multidecadal variability of the ENSO early-winter teleconnection to the North Atlantic in CMIP6 models: robustness and mechanisms

This study utilizes long CMIP6 pre-industrial control simulations to demonstrate that the multidecadal variability of the ENSO's early-winter teleconnection to the North Atlantic is likely driven by dynamical mechanisms, such as changes in tropical Indian Ocean convection, PDO phase, and jet stream background states, rather than mere sampling variability.

China’s dietary guidelines carry a hidden, regressive carbon cost that is nonetheless resolvable

By analyzing three million dietary records from China, the study reveals that while technological improvements in livestock emission intensity historically offset the carbon cost of dietary shifts toward animal-source foods, full compliance with current dietary guidelines would regressive increase the carbon footprint of the rural poor, a challenge that can be resolved through low-carbon dairy and greener protein alternatives.

Reservoir Sedimentation in Water-Scarce Contexts: Global Trends, Safety Implications, and Empirical Evidence from Uzbekistan

This paper reframes reservoir sedimentation in water-scarce contexts as a climate-amplified safety crisis rather than merely a capacity-loss issue, using global trends and empirical evidence from Uzbekistan to advocate for a risk-oriented framework that links sediment diagnostics to operational buffer degradation and adaptive governance triggers.
