Where is the Evidence? A Global Systematic Review of Sanitation System Resilience
Published: 2025-11-20
Subjects: Civil and Environmental Engineering
Despite sustained efforts over several decades, no region is projected to achieve universal sanitation access by 2030, according to international monitoring frameworks. Climate change is increasingly disrupting human and ecological systems, in turn deepening existing inequalities in access to essential services, including sanitation. Coupled with broader socio-economic and political dynamics, [...]
Coral reef commitments are largely absent from national biodiversity and climate frameworks

Subjects: Biodiversity, Climate, Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Marine Biology, Natural Resource Economics, Natural Resources and Conservation, Natural Resources Management and Policy, Oceanography, Other Oceanography and Atmospheric Sciences and Meteorology, Sustainability
Global agreements under the Convention on Biological Diversity (CBD) and the UN Framework Convention on Climate Change (UNFCCC) call for integrated action on biodiversity loss and climate change. Yet national implementation remains poorly understood, even for ecosystems highly vulnerable to warming, such as tropical coral reefs. Bleaching-level heat stress has affected over 85% of global reefs [...]
Thermal Power and Climate Change: A Data-Driven Analysis of Cause and Effect, 1800-2100
Published: 2025-11-20
Subjects: Education, Engineering, Life Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences
Since 2020, global politics have shifted sharply to the right—nowhere more visibly than in the United States and Europe. By 2024, this rightward turn in the U.S. culminated in open climate-change denial, the defunding of clean-energy initiatives, and a widespread rejection of scientific evidence. Major domestic and international institutions—NOAA, NASA, the U.S. Weather Bureau, EPA, USDA, FDA, [...]

Published: 2025-11-21
Subjects: Earth Sciences, Hydrology, Physical Sciences and Mathematics
Climate change is expected to impact hydrological regimes worldwide, including the Pacific Northwest of the United States. This study investigates how climate change will affect river discharge in the Puget Sound region of the State of Washington, with a focus on King and Pierce Counties. We simulated river discharge under historical and future conditions using the physically based, spatially [...]
Model of Cortical Mosaics (MMC): An Auto-Organized Evolutionary Trajectory from the Primitive Crust to Proto-Plates
Published: 2025-11-22
Subjects: Geology, Geophysics and Seismology, Tectonics and Structure
The structure and dynamics of Earth’s crust during the Hadean–Eoarchean remain one of the central challenges in geodynamics. Traditional models describe early states in terms of discrete regimes—stagnant lid, heat-pipe, episodic tectonics, or proto-plates—but none provides a continuous framework linking primitive fragmentation with the late emergence of plate tectonics. This work proposes the [...]
Arsenic immobilisation analysis at iron-manganese mineral phases with sustainable bioaugmentation
Published: 2025-11-21
Subjects: Chemistry, Environmental Sciences, Microbiology, Research Methods in Life Sciences
Alternate wetting and drying (AWD) cycles significantly influence arsenic (As) mobility and sequestration in contaminated soils, yet the mechanisms underlying As immobilisation at iron-manganese (Fe-Mn) mineral interfaces remain poorly characterised. This study investigates As entrapment within Fe-Mn mineral layers and evaluates long-term immobilisation stability when bioaugmented with Bacillus [...]
Morphological Signatures of Planetary Fusion: A Unifying Framework for Earth's Deep Heterogeneities
Published: 2025-11-21
Subjects: Physical Sciences and Mathematics
ABSTRACT Studies show that the theoretical feasibility, described in the literature, of gravitational interactions between celestial bodies under certain conditions may result in collisions with complete fusion of masses is acknowledged. Accordingly, the objective is to characterize their long-term structural and biological consequences. This study presents a testable conceptual model in which [...]
The Impact of GIA Corrections on Gravimetric Basin-Scale Ocean Mass Budgets
Published: 2025-11-22
Subjects: Climate, Geophysics and Seismology
Closing the sea-level budget is crucial for validating our understanding of climate change and sea-level rise. Satellite gravimetry (Gravity Recovery and Climate Experiment, GRACE) and altimetry are primary tools for measuring the ocean mass. Still, both datasets must be corrected for glacial isostatic adjustment (GIA), the ongoing viscoelastic response of the Earth to past deglaciation. [...]

Exposure to pluvial floods poses significant hazards, and predicting flood locations can be challenging. We developed a metric that quantifies relative flood hazard across Long Island, New York and the watersheds surrounding Long Island Sound. Based on surface topography, land surface characteristics, and historical weather patterns, we identified seven factors with readily available data that [...]
Weathering Trends Unveil K-Metasomatism in Bundelkhand Granitoids: Resolving the Pink–Grey Granitoid Paradox
Published: 2025-11-25
Subjects: Earth Sciences
The petrogenetic puzzle of pink coloration of granitoid rocks is rooted on the debate between primary magmatic versus metasomatic origin of K-feldspar, which, in turn, has persisted due to difficulties in distinguishing these processes through conventional petrographic methods. This study introduces a novel approach using chemical weathering patterns in ACNK ternary diagrams (Al2O3, CaO + Na2O, [...]
Timescales of Antarctic ice shelf loss via basal crevassing
Published: 2025-11-26
Subjects: Climate, Environmental Sciences, Physical Sciences and Mathematics
Antarctic ice-shelves are vulnerable to collapse in a warming climate. However, when this might happen is largely unknown, propagating significant uncertainty into sea-level-rise projections. To constrain this uncertainty, we use fracture modelling to predict the timescales on which crevasses fully penetrate ice-shelves, and consider how these timescales change under future warming. We find that [...]
