Global industrial disruption following nuclear war
Published: 2024-12-05
Subjects: Agriculture, International and Area Studies, Other Geography, Risk Analysis
Nuclear war poses catastrophic risks not only through its immediate effects and potential nuclear winter, but also through the disruption of industrial production on which modern civilization depends. In this study we estimate the reduction in global industrial output following a US-Russia nuclear war, as well as a more limited India-Pakistan exchange, by combining geospatial analysis with [...]
Harmonised airborne laser scanning products can address the limitations of large-scale spaceborne vegetation mapping
Published: 2024-12-04
Subjects: Life Sciences
Vegetation structure data are essential for understanding the functioning of terrestrial ecosystems and for informing various science-policy interfaces. Recent years have seen a growing demand for high-resolution data on vegetation structure, driving the prediction of such metrics at fine resolutions (1 m - 30 m) at state, continental, and global scales by combining satellite data with machine [...]
Smoke in your eyes: Investigating the effects of wind power on weather trends and climate using time series analysis
Published: 2024-12-04
Subjects: Climate
Time series analysis developed in the previous report [1] for UK mean summer temperature has been applied to further examples of weather trends, including temperature, rainfall and Sahara dust, and so at global, regional, national and local levels, in an attempt to assess whether wind power is having a deleterious effect on weather patterns. The analysis involves detrending weather data by [...]
Investigating the recommendations and governmental actions to address the emerging risks of vector-borne diseases in Canada’s changing climate: A scoping review
Published: 2024-12-04
Subjects: Public Health
Climate change is expected to increase the risks associated with vector-borne diseases, and its implications for human health are already observed across Canada. The objective of this review was to investigate the recommended adaptation strategies related to the risks associated with vector-borne diseases and examine how various levels of government in Canada are executing these recommended [...]
A Millimeter-Scale Change in Leaf Litter Placement Within Soil-Water Interfaces Alters Carbon Dioxide and Methane Emission
Published: 2024-12-04
Subjects: Earth Sciences, Environmental Sciences, Geochemistry, Soil Science, Sustainability
Flooded soils play a critical role in global carbon cycling, serving as significant reservoirs of soil organic carbon and sources of carbon emissions. Leaf litter, particularly from local vegetation, is a major contributor to soil organic carbon formation in these ecosystems, with its decomposition driving the production of carbon dioxide and methane. While numerous studies have investigated the [...]

Strengthening tropical cyclones are associated with more frequent hazardous material pipeline failures in the Eastern US
Published: 2024-12-04
Subjects: Engineering
Over 30,000 hazardous material pipeline (HMP) failures have caused nearly $11 billion in damages since 1970. Tropical cyclones, which cause more infrastructure damage than all other forms of natural disasters combined, are under-reported causes of HMP failures, largely due to historic policy around pipeline failure reporting. This study defines tropical cyclone-associated HMP failure frequency [...]
Geoscience for Earth Stewardship, Sustainability and Human Well-being: a conceptual framework for integrating planet, prosperity and people
Published: 2024-12-02
Subjects: Physical Sciences and Mathematics
There is a growing view that the mission of the Earth sciences ought to be reframed around the global sustainability agenda, and specifically the grand challenges of the UN Sustainable Development Goals. Yet the SDGs are criticised for lacking a coherent sense of the complex interconnections and synergies between its economic, environmental and social ambitions, for maintaining the impetus of [...]
An Integrated Geothermal Resource Assessment and Techno-Economic Analysis in Presidio County of the Trans-Pecos Region of Texas
Published: 2024-11-30
Subjects: Physical Sciences and Mathematics
Presidio County of the Trans-Pecos region of Texas has substantial, undeveloped geothermal resources. We conduct a thorough, multi-scale characterization of geothermal resources and assess techno-economics for power generation and direct use facilities. We integrate surface geology, high-resolution gravity, borehole geophysical logs, and core data for subsurface characterization and carry out [...]
Machine Learning Predicts Pedestrian Wind Flow from Urban Morphology and Prevailing Wind Direction
Published: 2024-11-30
Subjects: Earth Sciences, Environmental Sciences, Oceanography and Atmospheric Sciences and Meteorology
Pedestrian-level wind plays a critical role in shaping the urban microclimate and is significantly influenced by urban form and geometry. The most common method for determining spatial wind speed patterns in cities relies on numerical computational fluid dynamics (CFD) simulations, which resolve Navier-Stokes equations around buildings. While effective, these simulations are computationally [...]
Predictive modeling of seismic wave fields: Learning the transfer function using encoder-decoder networks
Published: 2024-11-30
Subjects: Physical Sciences and Mathematics
Wouldn't it be beneficial if we could predict the time series at a seismic station even if the station no longer exists? In geophysical data analysis, this capability would enhance our ability to study and monitor seismic events and seismic noise, particularly in regions with incomplete station coverage or where stations are temporarily offline. This study introduces a novel adaption of [...]
Modelling glacier mass balance and runoff in the Kaskawulsh River headwaters of southwest Yukon, Canada, 1980-2022
Published: 2024-11-30
Subjects: Glaciology, Hydrology
The highly-glacierized headwaters of the Kaskawulsh River are home to 9% of all glacier ice in Yukon, Canada, have been losing glacier mass at regionally representative rates, and were the source of a sudden meltwater-rerouting event in 2016 that has had significant downstream consequences. We use an enhanced temperature-index melt model driven by downscaled and bias-corrected climate reanalysis [...]
Effective permeability of fluvial lithofacies in the Bunter Sandstone Formation, UK
Published: 2024-11-30
Subjects: Oil, Gas, and Energy, Sedimentology, Water Resource Management
Understanding effective permeability is crucial for predicting fluid migration and trapping in subsurface reservoirs. The Bunter Sandstone of North-West Europe hosts major groundwater and geothermal resources and is targeted for CO2 and hydrogen storage projects. Here the effective permeability of fluvial facies within the Bunter Sandstone Formation was assessed using facies-scale models. Twelve [...]
The State of Global Catastrophic Risk Research: A Bibliometric Review
Published: 2024-11-30
Subjects: Agriculture, Biodiversity, Environmental Sciences, Environmental Studies, Food Science, Geography, Other Life Sciences
The global catastrophic risk (GCR) and existential risk (ER) literature focuses on analysing and preventing potential major global catastrophes including a human extinction event. Over the past two decades, the field of GCR/ER research has grown considerably. However, there has been little meta-research on the field itself. How large has this body of literature become? What topics does it cover? [...]
Oceanic Alkalinity and Titration Alkalinity: a novel straightforward approach in keeping with common general chemistry
Published: 2024-11-29
Subjects: Oceanography and Atmospheric Sciences and Meteorology
We present novel exact concepts of Oceanic Alkalinity and Titration Alkalinity that are in keeping with common chemistry. Oceanic Alkalinity is the small difference of the sum of charges of strong cations and the sum of charges of strong anions in seawater. This difference is compensated by the sum of charges of the weak anions minus the sum of charges of the weak cations. Titration Alkalinity [...]
