Abrupt permafrost thaw overwhelms vegetation-driven erosion reduction in sediment export on the Tibetan Plateau

Vegetation greening and abrupt permafrost thaw are reshaping sediment dynamics across the Tibetan Plateau, yet their relative effects on sediment delivery remain poorly quantified. Here we show that retrogressive thaw slumps are disproportionately important sediment sources, with...

Response of alpine runoff to the ‘Warming and Wetting’ climate change trend: a Budyko-based attribution analysis in the Daheba Basin

ABSTRACT Understanding runoff responses in al pine basins is essential for water-resource management under climate change. This study assessed runoff changes and their drivers in the Daheba Basin, northeastern Tibetan Plateau, using hydrometeorological and land-surface data for 1...

Forest and bioenergy expansion amplifies climate warming by accelerating regional cloud loss

Abstract. Land use and land cover change (LUCC) can exacerbate cloud-mediated climate warming. However, the long-term response of cloud cover to LUCC remains underexplored, particularly regarding differences between idealized and realistic forest expansion scenarios, as well as b...

Differential dissolution-induced concentration drift in sediment fingerprinting: Theory, validation, implications, and resolution

Reliable identification of sediment sources is fundamental to understanding erosion dynamics and implementing targeted watershed management. Sediment fingerprinting has therefore been widely applied to quantify sediment provenance. Here, we identified a previously overlooked proc...

Multi-time scale analysis of loess landform evolution for Dongzhi tableland, southwestern Loess Plateau, China

Study region Dongzhi tableland, southwestern Loess Plateau, eastern Gansu Province, China. Study focus The loess tableland has shrunk greatly over the past thousand years, and this trend is expected to continue. Predictions of loess tableland evolution can support the design and...

Contrasting rice-dryland crop rotation regimes drive divergent greenhouse gas emissions via labile organic carbon modulation, with trade-offs for crop yield

Context Optimizing crop rotations is essential for synergistically increasing yield and reducing environmental impacts. However, in rice-dryland crop rotation systems, the underlying mechanisms through which different dry-season crops influence subsequent rice yield and greenhous...

TPHH: a long-term (1901–2023) high-resolution (1∕30°) near-surface humidity dataset for the Tibetan Plateau generated via spatial downscaling based on hybrid-structure deep learning

The Tibetan Plateau acts as the “Asian Water Tower” and faces regional amplified warming compared to the global climate change baseline. Given the Tibetan Plateau's pronounced alpine terrain, i.e., significant elevation gradients within short horizontal distances, studies on clim...

Surface Subsidence Analysis and Prediction in an Open-Pit Mine Using Time-Series InSAR and a CL-TSF Hybrid Model

Surface subsidence in mining areas is a widespread, long-term, and slow-onset geological hazard that can induce cascading failures, including slope instability and ground collapse, thereby threatening infrastructure and human safety. Accurate characterization of its spatiotempora...

Sub-monthly volumetric evolution of the supraglacial lakes in Northeastern Greenland based on the topographic depression method

Study region Supraglacial lakes on the northeastern Greenland Ice Sheet (GrIS) during the melt seasons (May–September) from 2018 to 2025. Study focus This study develops a multi-parameter inversion framework for supraglacial lakes by integrating multi-source remote sensing data a...

Northern Boundary of Gondwana Inferred From Geochemical Characteristics of Granites East of the Eastern Syntaxis

Abstract The Bangong–Nujiang Meso-Tethyan Suture in eastern Tibet is still difficult to trace, mainly because Cenozoic shortening has juxtaposed narrow terranes, basins, and suture-related mélanges. We present field observations, zircon U-Pb ages, Lu-Hf isotopes, and whole-rock g...

Synchronously considering spatial dependence and temporal persistence into a deep learning based method for improving soil moisture spatial resolution

Accurate high-resolution soil moisture (SM) data are essential for understanding land–atmosphere interactions and supporting hydrological applications. However, soil moisture dynamics are inherently shaped by coupled spatial heterogeneity and temporal memory effects, requiring mo...

The 2024 cascading glacial lake outburst flood in the Thame Valley of Everest region, Nepal: process, impacts and implications

Abstract. On the afternoon of 16 August 2024, a catastrophic flood devastated Thame Village in the Everest region of Nepal. This event resulted from a cascading glacial lake outburst flood (GLOF), where the outburst of an upstream glacial lake triggered the failure of a downstrea...

An SPCL-Stacking ensemble learning framework for landslide susceptibility assessment

Abstract Background Machine learning has been increasingly applied to data driven landslide susceptibility assessment. However, false negative label noise introduced during negative sample selection and the limited predictive capability of single models remain unresolved issues....

Systematic Screening of Depression-Related Neurotoxicity Across 26 Bisphenols Reveals an ESR1–CREB1–GRIN2B-Associated Mechanism

Bisphenols (BPs) are widespread environmental endocrine disruptors, but their potential depression-related neurotoxicity has not been systematically assessed. Here, we combined machine learning (ML), network toxicology, molecular docking, and in vivo experiments to screen 26 bisp...

Topographic aspect shapes temperature lapse rates and land–atmosphere energy exchange in global mountains

Mountain regions exhibit complex thermal gradients that regulate land–atmosphere energy exchange, yet the global influence of topographic aspect on temperature lapse rates (LRT) remains poorly characterized. Here, we investigate global LRT patterns and their sensitivity to topogr...
