Peak loads, health, and energy equality: The effects of demand-side electricity efficiency interventions
Published: 2025-05-15
Subjects: Engineering, Oil, Gas, and Energy, Sustainability
Electrification is key for climate change mitigation but, if unmanaged, risks increasing energy poverty, inequalities, and peak electricity demand. While demand response to reduce peak electricity demand has been the subject of extensive research, the effects of energy efficiency interventions for wider health system and socioeconomic outcomes are less studied. This study assesses the impact of [...]
Peak demand, consumer costs, and socioeconomic effects: Considerations for distributed generation and energy storage
Published: 2025-05-15
Subjects: Engineering, Oil, Gas, and Energy, Sustainability
Electrification is a key approach for reducing greenhouse gas emissions but will increase peak demand, challenging electricity systems. Distributed generation (DG) from solar photovoltaic (PV) panels and battery storage are often offered as potential solutions. This study uses a previously validated agent-based model of residential electricity demand to assess the impact of solar DG on peak [...]
Holocene deglaciation of Prudhoe Dome, northwest Greenland
Published: 2025-05-15
Subjects: Earth Sciences, Geomorphology
Projections of future sea-level rise benefit from understanding the response of past ice sheets to interglacial warmth. Constraints on the extent of inland Greenland Ice Sheet (GrIS) recession during the Middle Holocene (~8 – 4 ka) are limited because geological records of a smaller-than-modern phase largely remain beneath the modern ice sheet. We drilled through 509 m of firn and ice at Prudhoe [...]
Modeling Daily Plume Specific Smoke Concentrations for Health Effects Studies with Estimates of Fire Size, Plume Age, and Fuel Type
Published: 2025-05-15
Subjects: Atmospheric Sciences, Environmental Health and Protection, Environmental Public Health, Statistical Models, Transport Phenomena
Inhaling smoke PM2.5 can cause adverse health effects ranging from acute (e.g., lung irritation) to chronic (e.g., lung cancer). Acute health effects have immediate implications for public health, requiring rapid response to minimize harm during an exposure window. Estimating acute health effects requires short-term (e.g., daily) estimates of fire-specific smoke PM2.5 concentrations at ground [...]
Accuracy and realism of CMIP6 candidate models in capturing dry, moist, and extreme precipitation anomalies in the Laurentian Great Lakes.
Published: 2025-05-15
Subjects: Physical Sciences and Mathematics
The Great Lakes are the world’s largest freshwater system, and understanding how Great Lakes precipitation dynamics will be modified by climate change is of critical importance. As the Great Lakes straddles a semi-arid to humid transitional region, trustworthy precipitation predictions must be generated by models that can accurately capture both thermodynamical and dynamical drivers of regional [...]
Reducing Bias in Cropland Soil Organic Carbon and Clay Predictions using Sentinel-2 Composites and Data Balancing
Published: 2025-05-15
Subjects: Physical Sciences and Mathematics
Accurate maps of cropland soil organic carbon stocks (SOCS) and clay content are essential for climate-smart agriculture. Soil reflectance composites (SRC), derived from multispectral bare soil observations, offer a scalable approach to high-resolution soil mapping. While studies often focus on maximizing model performance, challenges remain regarding (1) the bias introduced by masking and [...]
Turbulent Snow Transport and Accumulation: New Reduced-Order Models and Diagnostics
Published: 2025-05-15
Subjects: Atmospheric Sciences, Dynamical Systems, Fluid Dynamics, Glaciology, Hydrology, Meteorology, Non-linear Dynamics
Understanding and modeling snow particle dynamics in the atmosphere remains a significant challenge for atmospheric scientists, hydrologists, and glaciologists. Temporally and spatially varying rates of snow transport, deposition, and erosion are driven by atmospheric turbulence and further complicated by inertial particle dynamics. Even with perfectly resolved wind fields, accurately predicting [...]
Most bivalves and gastropods calcify indistinguishably from dual clumped isotope equilibrium
Published: 2025-05-14
Subjects: Education
Molluscan shell-carbonates are extensively used to reconstruct paleo-temperatures at sub-annual resolution. The accurate application of two widely used temperature proxies, the shell carbonate oxygen isotope (ẟ18O) and carbonate clumped isotope (Δ47) composition, is based on the assumption that kinetics in the DIC-H2O-CaCO3 system were either absent or invariant during shell formation and/or [...]
Precursory Patterns, Evolution and Physical Interpretation of the 2025 Santorini-Amorgos Seismic Sequence
Published: 2025-05-13
Subjects: Physical Sciences and Mathematics
The 2025 Santorini-Amorgos seismic sequence marked a significant episode of volcanic-seismic unrest in the Hellenic Volcanic Arc, offering a unique opportunity to investigate precursory patterns and the dynamic evolution of seismicity in a complex tectonic setting. Here, we analyze the preparatory phase of the crisis using a high-resolution relocated seismic catalog, anomaly detection, and [...]
The Interplay of Vegetation and Land-Atmosphere Feedbacks in Flash Drought Prediction
Published: 2025-05-13
Subjects: Atmospheric Sciences, Climate, Environmental Monitoring
Flash droughts, known for their rapid onset and intensification, pose a significant threat to agriculture and water resources. The 2011 Texas flash drought, with its widespread agricultural losses exceeding $7.6 billion and severe ecological consequences, was a stark demonstration of their devastating impacts. This study investigates the crucial role of vegetation in numerical modeling of flash [...]

In this study, naturally occurring jarosite samples from Kachchh India (considered to be Martian analogue) were characterized using Fourier Transform Infrared Spectroscopy (FTIR), Cathodoluminescence- Energy Dispersive X-ray Spectroscopy (CL-EDXS) and luminescence (thermoluminescence (TL), blue and infrared stimulated luminescence (BSL and IRSL) methods. FTIR and CL-EDXS studies suggested that [...]
Carbon-negative nickel mining to meet global mineral resource demands
Published: 2025-05-11
Subjects: Engineering, Physical Sciences and Mathematics
CO2-Enhanced Mineral Recovery (CO2-EMR) is a deep in situ mining technology that utilizes an engineered CO2 leaching fluid to extract nickel (Ni) and cobalt (Co) from subsurface ultramafic rocks, while simultaneously permanently mineralizing CO2 as carbonate minerals. This carbon negative process can contribute to meeting the mineral demands of current and emerging energy technologies. We [...]
