Soil acidity governs cropland phosphorus availability under future climate
Published: 2026-07-22
Subjects: Agriculture, Biogeochemistry, Soil Science
Understanding the response of agricultural phosphorus (P) cycling to climate change is fundamental for ensuring global food security and protecting planetary boundaries1–2. Recently, Wang et al.3 reported a drastic reduction in soil P bioavailability (32–34%) under long-term elevated carbon dioxide (eCO2) and warming in rice paddies, attributing it to enhanced geochemical sequestration via [...]
Strengthening informal urban functions for climate-resilient cities
Published: 2026-08-05
Subjects: Medicine and Health Sciences, Social and Behavioral Sciences
Informal workers provide essential urban functions, yet climate hazards can disrupt the conditions that sustain them. We propose the informal urban function as an analytical unit linking worker conditions, functional performance, and sustainability outcomes. The framework identifies structural conditions shaping capacity, climate pathways leading to continuity, erosion, disruption, or [...]
Multi-scale constraints resolve the 2025 Kamchatka megathrust rupture in a 3D heterogeneous Earth
Published: 2026-07-22
Subjects: Earth Sciences
Great megathrust earthquakes produce deformation over a wide range of spatial scales, yet how near‑trench, near‑field, and far‑field static displacements collectively constrain the same rupture remains poorly understood. Here we analyze the 29 July 2025 Mw 8.8 Kamchatka earthquake using spatially multi-scale observations: tsunami-derived initial uplift models for near-trench offshore deformation, [...]
Solar versus Diesel Powered Water Pumps in Meeting Sustainability Goals in Somalia, a qualitative study
Published: 2026-07-23
Subjects: Engineering, Life Sciences, Social and Behavioral Sciences
Somalia endowed with high solar energy is still using diesel energy as the major source of energy to pump drinking water. This put the country under question from achieving SDG 6 which targets universal access to clean and sustainably managed water. Therefore, this study gathers qualitative data from relevant key stakeholders in Puntland, Somalia through individual in-depth interviews and analyze [...]
Leveraging satellite embeddings and national expert annotations for country-level forest land use mapping
Published: 2026-07-24
Subjects: Environmental Monitoring, Environmental Sciences, Forest Sciences, Natural Resources Management and Policy
Spatially explicit information on forest as a land use can support climate change mitigation and biodiversity conservation actions, as well as supply-chain regulations, but many countries lack recent forest maps consistent with international definitions. Here, we assess a simple and accessible workflow for country-level Forest/Non-Forest mapping using expert reference labels from the FAO Forest [...]
Monetary transfers may be related to patterning in climate events, not just single extreme events
Published: 2025-07-26
Subjects: Climate, Environmental Studies, Physical and Environmental Geography, Remote Sensing
It is well-documented that households respond to climate events with climate adaptations: risk-management strategies like livelihood diversification, migration, or remittances – sending money and goods across distances. However, the focus is largely on responses to single climate events, while suggestive evidence indicates that temporal and spatial patterns across multiple events – including [...]
Incomplete coverage of the state of nature across biodiversity credit methodologies: an assessment using the State of Nature metrics framework
Published: 2026-09-02
Subjects: Biodiversity, Environmental Studies
Biodiversity credits are growing rapidly, yet the proliferation of methodologies has raised concerns about their quality and integrity. Because biodiversity cannot be reduced to a single common unit, methodologies differ in their choice of indicators; previous comparative studies, however, have examined only aggregation levels or taxonomic focus, leaving unaddressed how comprehensively [...]
Beyond the elite athlete: coupled climate-related health burdens in trail ultramarathon running
Published: 2026-07-23
Subjects: Biodiversity, Environmental Health and Protection, Environmental Public Health, Other Life Sciences
Climate change is simultaneously threatening the physical safety and psychological wellbeing of people who recreate outdoors, and degrading the ecological integrity of the natural environments in which they do so. Understanding who bears the greatest burden, which benefits are lost, and how adaptation strategies may shift rather than resolve risk is one of the defining challenges of planetary [...]
Moving fast without breaking things: The benefits of preprinting for CDR research
Published: 2026-08-06
Subjects: Biogeochemistry, Earth Sciences, Environmental Sciences, Other Earth Sciences, Other Environmental Sciences
Advocates of preprinting usually focus on its benefits to individual researchers — more feedback, citations, and visibility. We argue its greater value is collective: preprinting improves scientific coordination, which the carbon dioxide removal field needs in order to move fast without sacrificing rigor.
Independent lidar observations support declining low cloud cover trends seen in satellite and reanalysis records
Published: 2026-08-22
Subjects: Atmospheric Sciences, Climate
Low clouds strongly influence Earth's radiation budget, yet their response to climate change remains uncertain. Recent satellite and reanalysis studies indicate declining low cloud cover that may have contributed to increasing absorbed solar radiation, but independent ground-based evidence over land is limited. Here we show that ground-based lidar observations support a decrease in low cloud [...]
HyGage: Solving the Hysteresis Puzzle with a New Streamflow Monitoring Method
Published: 2026-02-12
Subjects: Engineering, Physical Sciences and Mathematics
The questionable reliability of discharges obtained using the traditional stage–discharge method under gradually varied flow conditions continues to motivate the search for improved monitoring approaches that support water resources management, streamflow forecasting, and multipurpose scientific investigations related to the water cycle. This paper introduces HyGage, a new physically based [...]
Fabric and strain analyses support a unified framework for sediment deposition, relaxation, and glass formation
Published: 2026-07-24
Subjects: Earth Sciences, Geophysics and Seismology, Physics, Sedimentology, Statistical, Nonlinear, and Soft Matter Physics
The kinetic energy of particles at deposition Ek is a distinguishing feature of all near-surface environments, varying due to particle mass and local stress field within the fluid that transports the particles. Once deposited, a granular fabric emerges that exerts control on the subsequent relaxation processes, including on whether, when, and how granular sediments catastrophically fail. Despite [...]
Physics-Informed Machine Learning in Hydrology and Water Resources: A Systematic Bibliometric Analysis
Published: 2026-10-06
Subjects: Civil and Environmental Engineering
This study presents a systematic bibliometric review of Physics-Informed Machine Learning (PIML) research in hydrology and water resources, examining the field's evolution in response to the limitations of traditional process-based models and data-driven approaches. Using a PRISMA-guided framework and a curated dataset from the Scopus database, the analysis evaluated publication trends, leading [...]
Reconstructing Satellite-Era Southern Ocean Temperature and Salinity Trends within Observational Uncertainty
Published: 2026-07-24
Subjects: Physical Sciences and Mathematics
Southern Ocean (SO) sea surface temperatures (SSTs) have exhibited large-scale cooling over the satellite era (1979-present). Several potential drivers of this cooling have been proposed -- including changes in winds, freshwater fluxes, and natural variability -- but their relative contributions have been challenging to identify because climate models largely fail to simulate the observed trend. [...]
