Subjects: Categorical Data Analysis, Databases and Information Systems, Engineering, Geographic Information Sciences, Mechanical Engineering, Nature and Society Relations, Other Engineering, Other Environmental Sciences, Other Mechanical Engineering, Other Physical Sciences and Mathematics, Physical and Environmental Geography, Risk Analysis, Software Engineering, Spatial Science
Wildfires pose an increasing risk to structures and communities located adjacent to or among vegetative landscapes. Yet most open landscape-scale fire modeling workflows still lack a reproducible way to represent buildings as combustible fuels rather than only as exposed assets or nonburnable developed land. This paper presents FireDX, a geospatial data engine that generates standardized, [...]
A Phanerozoic Atlas of Earth’s Atmosphere, Surface, and Interior Derived from the PANALESIS Plate Tectonic Model
Published: 2026-06-22
Subjects: Climate, Earth Sciences, Environmental Sciences, Geology, Other Environmental Sciences, Tectonics and Structure
Reconstructing the Earth system evolution through deep time requires spatially consistent, multi‑layer datasets that integrate geological, geophysical, and climatic information. Here we present a unified, high‑resolution (10×10km) global dataset describing the Earth’s evolution over the past 545 million years. This atlas provides 45 time slices spanning the Phanerozoic, each including quantified [...]
Less is more: how to capture carbon efficiently – lessons from long-term rock weathering and soil development in natural warm temperate ecosystems.
Published: 2026-06-15
Subjects: Other Environmental Sciences
Enhanced rock weathering (ERW) has been proposed as a viable strategy to offset greenhouse gas emissions. The field is currently plagued by uncertainty in the rates of C capture through alkalinity export, resulting from variation in extent and lag due to soil exchange, secondary minerals, and effects on soil organic carbon. Provided are quantitative estimates for weathering losses in these pools [...]
Carbon Dioxide Removal Supply Curves: A Multi-Model Assessment
Published: 2026-06-10
Subjects: Other Environmental Sciences
Carbon dioxide removal (CDR) is widely recognised as essential for pathways consistent with the Paris Climate Agreement. Yet the cost-dependent potential of CDR options, given resource competition, remains uncertain. Here we present CDR-supply curves assessing a range of CDR options across carbon price levels using five Integrated Assessment Models (IAMs) for 2035, 2050 and 2100. At 400 (200) $ [...]
Subsurface advective flow unveils the architecture of Earth’s crustal biosphere
Published: 2026-06-09
Subjects: Biogeochemistry, Environmental Microbiology and Microbial Ecology Life Sciences, Geology, Microbiology, Other Earth Sciences, Other Environmental Sciences
The subsurface biosphere is one of Earth’s largest microbial reservoirs, yet its spatial extent remains poorly constrained due to limited direct access. Here we propose using the integrated environmental readouts encoded in deep subsurface fluids to shift from simply mapping where life can be detected to constraining where life can exist. Deeply-sourced advective fluids provide an integrated [...]
Polar ice-cores unravel the formation of a UV window during magnetic field collapse ~ 42 ka BP
Published: 2026-05-08
Subjects: Earth Sciences, Environmental Sciences, Geochemistry, Other Environmental Sciences, Physical Sciences and Mathematics
During geomagnetic excursions (GEs), compromised magnetic field and increased cosmic-ray bombardment can deplete the ozone layer forming ‘UV window(s)’ in the Earth’s atmosphere. Here, using triple sulfur-isotope systematics in polar ice-core sulfate record spanning 600 years of the Laschamp GE, we provide direct evidence of the formation of a UV window. Several events of UV-induced anomalous [...]
Croplands as thermodynamic agents in a high-CO2 world
Published: 2026-04-28
Subjects: Other Environmental Sciences
Rising atmospheric CO2 is widely expected to influence crops through physiological pathways, yet croplands are also extensive physical interfaces that regulate land–atmosphere energy exchange. Despite covering 12–15% of Earth’s ice-free land surface, their role in surface energy balance under elevated CO2 remains poorly constrained. Most CO2 enrichment studies have not explicitly resolved the [...]
Before the Threshold: Deceptive Stability, Buffer Slack, and Earth System Transitions
Published: 2026-04-20
Subjects: Biogeochemistry, Climate, Earth Sciences, Geochemistry, Other Environmental Sciences
Earth history includes episodes in which persistent biological or geophysical byproduct loads are absorbed by finite environmental sinks and buffers, preserving apparent stability while the capacity to absorb further stress declines. This paper synthesizes literatures on Earth system revolutions, redox transitions, mass extinctions, and Anthropocene change into a comparative framework termed [...]
Geostatistical Assessment of Shallow Groundwater Risk in Urban Coastal Virginia: A Case Study from Virginia Beach
Published: 2026-04-14
Subjects: Civil and Environmental Engineering, Engineering, Environmental Sciences, Geology, Hydrology, Life Sciences, Other Environmental Sciences, Water Resource Management
Urban groundwater assessments in coastal cities often rely on public monitoring datasets that are spatially uneven and temporally discontinuous. This study evaluates shallow groundwater risk in Virginia Beach, Virginia, using 30 years of records (1991–2020) from 121 monitoring wells for groundwater levels and 55 wells with groundwater‑quality data for chloride (Cl), iron (Fe), and manganese (Mn). [...]
Stress testing insurance market stability under climate risk
Published: 2026-04-01
Subjects: Environmental Engineering, Other Earth Sciences, Other Environmental Sciences, Risk Analysis
Climate change, urban development, and evolving insurance markets threaten the stability of disaster-risk financing. Homeowners insurance is embedded in a layered network of reinsurers, capital markets, and public backstops that can be overwhelmed by extreme events. We develop a probabilistic risk propagation model linking tropical cyclone wind and flood losses to Florida’s residential insurance [...]
Cervical Cancer and Climate Change

Subjects: Environmental Public Health, Environmental Sciences, Other Environmental Sciences
Background: The research question guiding this scoping review was: "What does the literature reveal (since January 1, 2005) about the association between climate change—or its underlying environmental drivers—and cervical cancer?" Methods: We conducted a comprehensive literature search using two major electronic databases: PubMed and Web of Science, for January 1, 2005, through July 30, 2024. 522 [...]
Reducing the global human footprint on lake water quality near river inlets
Published: 2025-11-12
Subjects: Fresh Water Studies, Hydrology, Other Environmental Sciences, Remote Sensing, Water Resource Management
Human activities have degraded lake water quality globally, leading to toxic algae proliferation and anoxia. The spatial variability of these impacts within lakes and the potential for targeted nutrient pollution reduction to improve water quality remain however underexplored at the global scale. Using 742 million chlorophyll-a (chl-a) estimates from six satellite sensors (daily, 1–4 km [...]
Hazomes: Earth’s natural multi-hazard terrestrial disturbance regimes
Published: 2025-10-22
Subjects: Climate, Other Earth Sciences, Other Environmental Sciences, Other Oceanography and Atmospheric Sciences and Meteorology, Other Planetary Sciences, Physical and Environmental Geography, Spatial Science, Sustainability
Ecosystems and societies have evolved together and are shaped by local natural hazard regimes. We introduce hazomes, an Earth classification based on multi‑hazard disturbance patterns. By combining open‑source intensity and return period data for eight hazard types, we identify thousands of distinct terrestrial disturbance regimes. Hazomes aims to deepen insight into ecosystem and societal [...]
fasterRaster: GIS in R using GRASS for large vectors and rasters
Published: 2025-10-17
Subjects: Geomorphology, Hydrology, Other Earth Sciences, Other Environmental Sciences
Within the R ecosystem, packages like terra and sf are the go-to solutions for most geospatial analyses, yet can struggle with large rasters and vectors. The Geographic Resources Analysis Support System, or GRASS, offers solutions that are often more efficient for large data. However, using GRASS through R requires users to become familiar with GRASS-specific syntax and data constructs. The [...]
