Water Security under Climate Change in Small Island Developing States: A Hydro-Socio-Metabolic Analysis of Malé, The Maldives

This study introduces a novel hydro-socio-metabolic framework to analyze water security risks in Small Island Developing States, using Malé, Maldives as a case study to reveal how shifting from groundwater to energy-intensive desalination creates systemic vulnerabilities and to advocate for systemic climate adaptation strategies.

Existing Microbial Water Quality Monitoring approaches under the Umbrella of Water Safety planning in Ethiopia, in comparison to other East African countries: A Systematic Review

This systematic review compares Ethiopia's microbial water quality monitoring practices under Water Safety Planning with those of seven other East African countries and WHO recommendations, revealing statistically significant variations in monitoring approaches across the region while concluding that current national-level implementations remain insufficient despite some improvements.

Multispeed mitigation strategies to limit mid-century overshoot and return to 1.5°C

This study proposes a "multispeed mitigation" strategy combining immediate actions against super pollutants and deforestation with long-term energy transition efforts to limit peak warming to 1.9°C by 2060 and return global temperatures to 1.5°C by 2130, demonstrating that while fast mitigation levers are critical for minimizing overshoot, both fast and slow strategies are essential for achieving long-term climate goals.

Darcy-Scale Experimental Investigation of Intermittent Particle Transport in Porous Media and its Impact on Injectivity

This study utilizes long-duration dynamic core flooding experiments on Bentheimer sandstone to demonstrate that while cyclic injection of particle-laden water causes transient injectivity recovery during shut-in periods, it ultimately promotes the formation of more compact external filter cakes and alters near-wellbore damage mechanisms compared to continuous injection.

Intrinsic AMOC Eigenmodes for Bond-Cycle Variability

This study proposes that millennial-scale Bond cycle variability arises from intrinsic Atlantic Meridional Overturning Circulation (AMOC) eigenmodes that become weakly damped and observable under specific background conditions, such as a weakened mean AMOC or freshened Southern Ocean, thereby reconciling discrepancies between paleoclimate records and climate model simulations.

Hydrochemical controls and groundwater-quality implications of fluoride enrichment in the North China Plain and Taihang Mountain region

This study compares groundwater fluoride enrichment in the North China Plain and Taihang Mountain region, revealing that while the mountainous area has higher fluoride concentrations, the underlying hydrochemical controls in both regions involve a complex interplay of mineral dissolution, carbonate equilibrium, cation exchange, and evaporation rather than a single process.

On the present and future changes in heatwave characteristics over the UK using RegCM4

This study utilizes HadGEM3 and downscaled RegCM4 simulations to demonstrate that future UK heatwave frequency, intensity, and persistence are strongly emission-dependent, with the high-emission SSP5 scenario projecting significantly more severe heat stress and longer-lasting atmospheric blocking compared to the moderate SSP2 pathway.

Evaluating Seismic Refraction for Shallow Saturated-Zone Delineation across Contrasting Lithological Settings

This study demonstrates that the effectiveness of seismic refraction in delineating shallow saturated zones is primarily controlled by lithological conditions, showing clear success in alluvial and siliciclastic-evaporitic settings due to distinct P-wave velocity contrasts, while failing in clay-rich environments where such contrasts are absent.
