From radiative signal to early warning: the integrated IRIS index for detecting, explaining and projecting intraseasonal rainfall breaks in the Sahel (1992–2050)

This study critically evaluates the Sahel Integrated Radiative Index (IRIS) as a potential early-warning tool for intraseasonal rainfall breaks, finding it to be a physically grounded state descriptor with limited predictive skill due to inherent rainfall stochasticity and a projected climate signal too weak to distinguish from natural variability by 2050.

Geochemical Assessment and Source Apportionment of Soil Heavy Metals in the Taihe Iron Ore Mining Area, Sichuan, China

This study integrates geochemical analysis, spatial interpolation, and multivariate receptor modeling to assess soil heavy metal contamination in the Taihe Iron Ore Mining Area, revealing that while the region faces low overall ecological risk, copper and zinc enrichment stems primarily from mining activities whereas lead contamination is driven by traffic and residential sources.

Avian Species Composition and Diversity in Ten-Year-old Biodiversity Offsets for Energy Infrastructure in Tropical Forest Reserves

Ten years after implementation, biodiversity offsets for energy infrastructure in Uganda's Gangu and Mabira forest reserves support higher overall bird diversity dominated by generalist species but have not yet achieved compositional equivalence with impact sites or provided suitable habitat for forest specialists.

Flood Hazard Assessment in Adama City of Ethiopia by Using MCDM Approach

This study employs a Fuzzy Analytical Hierarchy Process (FAHP) integrated with Geographic Information Systems (GIS) to assess flood hazards in Adama City, Ethiopia, demonstrating that the FAHP approach effectively handles expert uncertainty to produce a robust hazard map identifying rainfall, flow accumulation, and elevation as primary drivers while providing a scientifically sound foundation for urban planning and mitigation strategies.

Integrated 2D Gravity and Vertical Electrical Sounding Modeling for Groundwater Potential Assessment in the Megado Area, Southern Ethiopia

This study integrates Vertical Electrical Sounding and gravity modeling in southern Ethiopia to characterize a fractured basalt aquifer system, revealing that fault-bounded basement lows serve as primary groundwater accumulation sites and validating the methodology through successful borehole drilling.

Seasonal arsenic dynamics in a shallow eutrophic lake from a naturally enriched region: links between sediment mobilization and bioaccumulation across trophic levels

This study reveals that seasonal warming in a naturally arsenic-enriched shallow lake triggers sediment mobilization and increased dissolved arsenic, which leads to bioaccumulation in primary producers and invertebrates but is mitigated in fish through physiological regulation, resulting in a clear biodilution pattern across the food web.

Modeling Terrestrial Carbon Sequestration: A Review-Based Mathematical Framework Integrating Remote Sensing and GIS

This review-based study proposes a scalable mathematical framework that integrates Remote Sensing and GIS with vegetation indices and allometric equations to enable accurate, high-resolution spatial quantification of terrestrial carbon stocks, thereby supporting climate policy and verifiable carbon credit mechanisms.

Multi-Objective Gravity Data Inversion for Basement Depth Estimation in Sedimentary Basins

This study proposes and validates an adaptive multi-objective optimization algorithm (AMALGAM) that simultaneously minimizes data misfit and model smoothness to accurately estimate basement depth in sedimentary basins, eliminating the need for post-inversion smoothing or weighting schemes while producing a robust set of optimal solutions.

Reducing Methane Emissions Along Global Natural Gas Supply Chain through Import Standards

This study demonstrates that while methane-intensity-based import standards can significantly reduce emissions for major natural gas importers by shifting trade to lower-intensity suppliers, achieving deeper global reductions requires combining these policies with accelerated energy transitions or broader producer-side abatement to prevent emissions leakage to unconstrained markets.

Pacific-Origin Rossby Waves Modulated by Atlantic SSTs in CMIP6 Large Ensembles

This study utilizes CMIP6 large ensembles to demonstrate that Atlantic sea surface temperature anomalies modulate the propagation of Pacific-origin Rossby waves into Europe during boreal summer by altering upper-level jet structures, thereby explaining inter-model variability in trans-basin teleconnections and European summer climate predictability.
