Exploring the Impact of Climate Change on Community Sustainability in Atlantic Canada: A Transdisciplinary Approach
Published: 2025-01-17
Subjects: Education, Social and Behavioral Sciences
This paper examines the significant impacts of climate change on community sustainability in Atlantic Canada, particularly for vulnerable populations. Rising temperatures and sea levels threaten livelihoods, infrastructure, and ecosystems, necessitating a transformative approach to avoid maladaptation. Current strategies primarily rooted in natural sciences and economic models lack the [...]
Influence and Prediction of Planetary Orbital Changes on Earth's Atmospheric Water Vapor Variations
Published: 2025-01-17
Subjects: Education, Physical Sciences and Mathematics
A few people have gradually realized that the superposition effect of different planets in the solar system on Earth under high-speed motion and dynamic equilibrium can sometimes trigger extreme natural disasters. Due to the relatively regular changes in the relative positions of the Sun, Moon, and Earth, this study considers these three planets as independent systems. The orbits of other planets [...]
Updated high-resolution climate projections for Ireland
Published: 2025-01-17
Subjects: Physical Sciences and Mathematics
Climate change poses a significant risk to Ireland’s economy, society and environment, and therefore it is imperative that planners and policymakers are adequately informed about future climate change so that appropriate mitigation and adaptation measures can be implemented. The main objective of this project was to evaluate the effects of climate change on the future climate of Ireland using [...]
Shallow fault zone structure affects rupture dynamics and ground motions of the 2019 Ridgecrest sequence to regional distances
Published: 2025-01-17
Subjects: Physical Sciences and Mathematics
Seismic faults are surrounded by damaged rocks with reduced rigidity and enhanced attenuation. These damaged fault zone structures can amplify seismic waves and affect earthquake dynamics, yet they are typically omitted in physics-based regional ground motion simulations. We report on the significant effects of a shallow, flower-shaped fault zone in foreshock-mainshock 3D dynamic rupture models [...]
On the Definition of an Independent Stochastic Model for InSAR Time Series
Published: 2025-01-16
Subjects: Engineering, Physical Sciences and Mathematics
InSAR enables the estimation of displacements of (objects on) the Earth’s surface. To provide reliable estimates, both an independent stochastic and functional model are re- quired. However, the intrinsic problem of InSAR is that both are unknown. Here we propose an independent definition of the stochastic model, via an approximation scheme for the variance- covariance matrix for [...]
OceanTracker 0.5: Fast Adaptable Lagrangian Particle Tracking in Structured and Unstructured Grids
Published: 2025-01-16
Subjects: Numerical Analysis and Scientific Computing, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Particle tracking is frequently used to compute particle movements within hydrodynamic ocean models; however, modelling millions of particles is computationally challenging. OceanTracker is designed to minimise the time required to obtain results from particle tracking. Firstly, by being computationally fast, it enables users to scale to large numbers of particles, thus obtaining better [...]
Hypereutrophication, Hydrogen Sulfide, and Environmental Injustices: Mechanisms and Knowledge Gaps at the Salton Sea
Published: 2025-01-16
Subjects: Earth Sciences, Environmental Studies, Physical and Environmental Geography, Physical Sciences and Mathematics
The Salton Sea, California’s largest lake, is undergoing significant environmental degradation, which has adverse health effects on nearby rural communities, who are primarily Latinx and Torres Martinez Desert Cahuilla Indian. Over the past two decades, the lake’s water levels have steadily dropped. Water conditions in the Sea, characterized by low oxygen and high nutrient levels, favor the [...]
Spatio-temporal analysis of the extremes of precipitation and temperature in the capital cities of India
Published: 2025-01-15
Subjects: Other Physical Sciences and Mathematics
This study presents an analysis of extreme temperature and precipitation events in the capital cities of India during 40-years study period (1982-2022). Daily maximum temperature, minimum temperature, and rainfall from NASA-POWER were used to compute climate extreme indices, recommended by the Expert Team on Climate Change Detection and Indices (ETCCDI) and Expert Team on Sector-Specific Climate [...]
UrbanTALES: A Comprehensive LES Dataset for Urban Canopy Layer Turbulence Analyses and Parameterization Development
Published: 2025-01-14
Subjects: Physical Sciences and Mathematics
The urban canopy layer (UCL) exhibits complex, heterogeneous flow patterns shaped by urban geometry. Traditionally, research has relied on microscale simulations over limited and often idealized building arrays, leaving a need for more extensive datasets to capture the dynamics across diverse urban neighborhoods. Responding to this gap, we developed an extensive dataset, known hereafter as [...]
Intensifying risk of mass human heat mortality if historical weather patterns recur
Published: 2025-01-14
Subjects: Physical Sciences and Mathematics
The potential death toll of worst-case extreme heat events is crucial for climate risk analysis and adaptation planning. We estimate this quantity for Europe using machine learning to calculate the intensity of historical heat waves if they occur at present or future global temperatures, combined with empirical exposure-response functions to quantify the resulting mortality. Each event is [...]
An updated version of the SZ-plugin: from space to space-time data-driven modeling in QGIS
Published: 2025-01-14
Subjects: Geology, Geomorphology, Software Engineering, Statistical Models
The geospatial community usually makes use of GIS environments to handle databases and pre-process their information. Actual analyses, especially data-driven ones, are performed outside GIS platforms. This interrupts the flow of information and the processing chain in a number of I/O operations that inevitably slow down the overall analytical protocols. The first version of the SZ-plugin [...]
Climate change impacts on compound renewable energy droughts under evolving infrastructure in the Western United States
Published: 2025-01-14
Subjects: Oil, Gas, and Energy, Power and Energy, Sustainability
As variable renewable energy resources become a larger part of the generation mix in the United States (U.S.), so does the potential impact of prolonged periods of low wind and solar generation, known as variable renewable energy (VRE) droughts. In a future decarbonized or low-carbon grid, naturally occurring VRE droughts need to be evaluated for their potential impact on grid reliability. This [...]
Readapting PhaseNet to Laboratory Earthquakes: AEsNet, a Robust Acoustic Emission Picker Illuminating Seismic Signatures of Different Fault Gouge Materials

Laboratory acoustic emissions (AEs) represent microslip events analogous to small- scale earthquakes, providing valuable insights into the mechanics of frictional instabilities. With technological advancements in acoustic monitoring, thousands of AE waveforms can now be collected in minutes of experimental time, requiring efficient methods for their detection and analysis. In this study, we [...]
