Very Wet Day Precipitation (R95p) Projections under 1.5°C, 2°C, and 3°C Global Warming Levels: A CMIP6 Multi-Model Analysis for the Rapti River Basin

This study utilizes a CMIP6 multi-model analysis to demonstrate that very wet day precipitation (R95p) in the Rapti River Basin intensifies significantly across 1.5°C, 2°C, and 3°C global warming levels, with the ACCESS-ESM1-5 model projecting the most substantial increases and highlighting critical spatial heterogeneity and the urgent need for adaptive flood management strategies.

The Hidden Material Footprint and Circularity Limits of Spacecraft Expansion

This study quantifies the hidden material footprint of over 18,000 historical and projected spacecraft, revealing that their rapid expansion will drastically intensify environmental pressures and critical resource depletion due to the unrecoverable nature of embedded materials, thereby creating a significant trade-off between space exploration and terrestrial sustainability.

A hierarchical cascade derivation of the bathymetric spectral order governing tsunami coda excitation and scattering attenuation

This paper demonstrates that the von Kármán order governing tsunami coda excitation and scattering attenuation is not a free parameter but is fundamentally fixed by the hierarchical NN-body cascade structure of the seafloor, thereby predicting a Mittag-Leffler temporal decay for tsunami codas without the need for empirical fitting.

Flood-scale shifts in effective sediment source zones and signal transmission through a gated-weir cascade

By integrating satellite imagery with hydrological data from 38 monsoon floods, this study reveals that sediment connectivity in the Nakdong River's gated-weir cascade is driven by flood-specific source activation and infrastructure operation rather than nominal storage, resulting in significant shifts in sediment source zones and minimal attenuation of sediment signals across the system.

From Grey Gap to Ecological Resilience: Quantifying the Spatiotemporal Evolution of Hybrid Water Infrastructure in a Subtropical Megacity (1994–2024)

This study demonstrates that in Taipei's Danshui River Basin, a hybrid approach coupling decentralized Green Infrastructure with centralized Grey systems effectively bridged sanitation gaps and sustained ecological resilience over three decades, offering a cost-effective and scalable governance model for rapidly urbanizing Global South cities.

Persistence of cross-media toxic release profiles across U.S. counties

This study analyzes U.S. county-level toxic release data from 2015 to 2022 and finds that while cross-media release profiles exhibit high temporal persistence, their stability is meaningfully dependent on dominant local industrial sectors, suggesting that reported mass totals should be interpreted with caution regarding environmental risk due to their lack of toxicity weighting and sensitivity to industrial composition.

Large variation in soil phosphorus availability and tree nutritional strategies in humid temperate forests on carbonate rocks

This study reveals that soil phosphorus availability in humid temperate carbonate rock forests varies drastically with the degree of soil acidification during pedogenesis, driving distinct nutritional strategies where specialized plants exhibit lower phosphorus resorption efficiency compared to generalists.

Spatial heterogeneity and source-to-sink processes of heavy metals in a karst Pb-Zn mining area

This study develops and applies a transparent cross-media evidence framework to distinguish quantitative heavy metal source-to-sink processes in a karst Pb-Zn mining area, identifying Cd, Cu, Pb, and Zn as mine-derived pollutants transported via river sediments to localized plain accumulations, while differentiating them from background-controlled elements like Cr and Ni.

Mining strongly reduces local biodiversity across terrestrial and freshwater ecosystems

This global meta-analysis reveals that mining acts as a major and pervasive driver of biodiversity loss, reducing local species richness by roughly half and causing severe abundance declines across both freshwater and terrestrial ecosystems, with impacts significantly exceeding those of other major anthropogenic pressures.

Different drivers shape global inequalities in water-monitoring reporting

This study reveals that global inequalities in water-monitoring reporting are driven by distinct socioeconomic, scientific, governance, and cultural factors specific to each monitoring component, thereby challenging one-size-fits-all approaches and underscoring the need for tailored strategies to achieve SDG 6.
