Simulation of the Impacts of Spring Diversions on Streamflow in the Strawberry Creek Watershed, San Bernardino County, California, Using an Integrated Hydrological Model
Published: 2025-11-21
Subjects: Physical Sciences and Mathematics
The Strawberry Creek watershed, situated in the San Bernardino Mountains of southern California, features a group of natural springs known as Arrowhead Springs that have been augmented with diversions in the form of sub-horizontal borings and tunnels. Understanding the impact of these structures on streamflow through groundwater capture is crucial for managing surface-water resources in this [...]
Wetter Winters, Drier Summers: Quantifying the change in hydrological response around the Puget Sound area using the wflow_sbm hydrological model and CMIP6 projections
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 [...]
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 [...]
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 [...]
Technical Brief: Uncovering Sub-Regional Drivers of Deforestation in the Amazon: A Tool for Targeted Solutions
Published: 2025-11-20
Subjects: Environmental Sciences, Natural Resources and Conservation, Sustainability
This technical brief provides the first region-wide analysis of the commodity-specific agricultural drivers of deforestation across the Amazon region at a sub-national level, offering insights to inform more effective and equitable conservation policy. We achieve this by integrating sub-national agricultural production statistics with satellite data on land use and commodity production for each [...]
Long-term incubations reveal geochemical controls on wood biomass preservation at the anoxic sediment-water interface
Published: 2025-11-20
Subjects: Life Sciences
Ocean-based carbon dioxide removal (CDR) strategies increasingly consider biomass burial in anoxic marine basins as a pathway for long-term carbon storage. To evaluate its stability and environmental impact, we conducted 14-month bottle incubations testing three configurations of terrestrial wood under anoxic conditions: suspended in the water column, placed on the sediment surface, and buried [...]
Access to Monitoring Data Reduces Methane Intensity at Operational Oil and Gas Facilities
Published: 2025-11-20
Subjects: Environmental Monitoring, Oil, Gas, and Energy
Methane intensity is defined as methane gas emitted to the atmosphere per oil and gas product throughput at various steps in the supply chain. It is the standard metric used by industry stakeholders to assess methane emissions performance. Many studies have assessed the capabilities of methane emission measurement systems, but no studies have quantified the effect on methane intensity of oil and [...]
A systematic review of microplastic pollution in rivers across Asia
Published: 2025-11-20
Subjects: Physical Sciences and Mathematics
Microplastics are widely distributed in the aquatic ecosystem globally. They pose potential risks and harm to the ecosystem and human health. Contamination of river environments by microplastics has raised concern due to its negative effect on the aquatic system. Asian rivers serve the world’s most populous continent, encompassing many developing countries experiencing rapid development and [...]
Attention-Based Deep Learning for Runoff Forecasting: Evaluating the Temporal Fusion Transformer Against Traditional Machine Learning Models
Published: 2025-11-20
Subjects: Engineering, Life Sciences
Reliable runoff forecasting is critical for water management and flood preparedness in Nepal’s steep, data-scarce catchments. Traditional models such as SWAT provide process insights but demand extensive calibration and detailed inputs often unavailable in such regions. Recent advances in attentionbased deep learning offer new opportunities to capture temporal dependencies with improved [...]
Can Carbon Information Disclosure Enhance Firms' New Quality Productivity? Evidence from Empirical Analysis of Chinese Listed Companies
Published: 2025-11-20
Subjects: International and Area Studies
As global efforts to tackle climate change deepen, the role of carbon information disclosure in enhancing the new quality productivity of enterprises has attracted growing attention. This paper, using data from Chinese listed companies between 2015 and 2023, investigates the effect of carbon information disclosure on new quality productivity in enterprises and the mechanisms behind it. The [...]
Agrivoltaics can reduce heat exposure for farmworkers
Published: 2025-11-20
Subjects: Agriculture
Heat exposure endangers over 850 million farmworkers, with agricultural labor projected to account for 60% of heat-related working-hour losses by 2030. Agrivoltaic systems, which integrate solar panels with agriculture, may reduce this risk by modifying the thermal environment farmworkers operate within, yet their impact on heat exposure remains unquantified. We evaluate wet bulb globe [...]
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, [...]
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 Europe and the United States. 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, [...]
