Ancient DNA and lipid biomarkers quantify the climate sensitivity of highland shrubification in Iceland
Published: 2025-07-11
Subjects: Physical Sciences and Mathematics
Future changes in high latitude shrubification are expected to lead to changes in ecosystem structure and positive climate feedbacks, but the rates and elevational range of shrubification are still poorly constrained. Using a sediment record from a small lake in Iceland’s eastern highlands (422 m asl), we merge a sedimentary ancient DNA (sedaDNA) record of Betula with mean summer lake temperature [...]
Integrated Disaster Nursing Response for Public Healthcare Settings in Pakistan: A Sequential Mixed Method Approach Study Protocol
Published: 2025-07-11
Subjects: Public Health
Abstract Background Natural disasters such as floods, earthquakes, and hurricanes pose significant threats to human lives and infrastructure, particularly in low-lying regions of Pakistan. Among the most vulnerable areas are Sanghar and Dadu in the Sindh province, which experience recurrent flooding. These disasters often overwhelm healthcare systems and underscore the urgent need for adequately [...]
Thermal analysis of meso-scale high-temperature Borehole Thermal Energy Storage (BTES) systems with varying operational cycles
Published: 2025-07-12
Subjects: Engineering, Environmental Engineering, Other Mechanical Engineering
High temperature and short-term subsurface heat storage using BTES is a promising option and an emerging technology for increasing the fraction of renewable energy in the heat sector and supplying stored heat at high and directly usable temperatures. Investigation of thermal interactions of multiple BHEs employed for high-temperature cyclic storage operations is required to understand the system [...]

A Critical Review of Life Cycle Assessment in Shrimp Aquaculture: Uncovering Methodological Dominance and Analytical Blind Spots
Published: 2025-07-12
Subjects: Life Sciences
Life Cycle Assessment (LCA) is increasingly used to evaluate the environmental impacts of shrimp aquaculture, a rapidly expanding global food sector. However, existing shrimp LCA studies report widely divergent results, varying by more than fiftyfold across key impact categories. This systematic review identified 16 peer-reviewed shrimp LCAs and investigates the reasons for these discrepancies, [...]
Recommendations for improving the design, amenity and performance of privately owned, small-scale biobasins
Published: 2025-07-13
Subjects: Engineering, Life Sciences
Due to spatial constraints in cities, it is increasingly challenging to integrate appropriate water sensitive urban design (WSUD) solutions. There has been a shift from larger, precinct-scale bioretention systems owned by local governments to smaller scale ‘biobasins’ managed by private landholders. This shift has brought about unique challenges in regulation, design, maintenance, and [...]
Volcano-tectonic controls on magmatic evolution at Campi Flegrei, Italy: insights from thermodynamic modelling
Published: 2025-07-14
Subjects: Earth Sciences, Geochemistry, Physical Sciences and Mathematics, Volcanology
Campi Flegrei caldera (Naples, southern Italy) is one of the most hazardous volcanoes on Earth, having produced more than 70 eruptions in the past 15 kyr, and currently showing significant signs of unrest within a densely populated part of Europe. Post-15 ka eruptions span a range of eruptive styles and compositions, which broadly correlate with the spatial and structural location of vents within [...]
Screening Global Solar and Wind Energy Investment Potential Accounting for Drought and Surplus
Published: 2025-07-14
Subjects: Environmental Engineering, Oil, Gas, and Energy, Risk Analysis, Sustainability
Climate-induced variability of solar and wind energy impacts renewable electricity scaling. Long duration renewable energy droughts, i.e., extended periods of renewable supply deficits, lead to contract penalties or use of thermo-electric sources, while long duration surpluses result in curtailment or in low energy prices and revenue. We present the first global assessment of the implied [...]
Comments on “Osmosis Drives Explosions and Methane Release in Siberian Permafrost” by Morgado et al. 2024
Published: 2025-07-16
Subjects: Earth Sciences
This commentary addresses the model proposed by Morgado et al. (2024) in their paper, “Osmosis Drives Explosions and Methane Release in Siberian Permafrost.” The model explores the role of osmotic pressures in explaining the formation of gas escape craters in the Western Siberian permafrost. While it presents a novel perspective on permafrost dynamics under climate change, three significant [...]
Slowly migrating fracture swarms in an actively serpentinizing borehole
Published: 2025-07-24
Subjects: Earth Sciences, Physical Sciences and Mathematics
Peridotite rocks are primary targets for engineered geological carbon sequestration efforts because they accommodate transfer carbon from aqueous fluids to rock during alteration reactions. Sequestration efforts must necessarily open fractures in the rocks surrounding a pumped borehole, but the current understanding of fracture growth during serpentinization of peridotite is limited to [...]
Soil Remineralization in Agroecological Systems: A Critical Review
Published: 2026-04-28
Subjects: Agriculture, Earth Sciences, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics
Soil degradation threatens global food security, human nutrition, biodiversity, water resources, and climate stability by depleting soil organic matter, exhausting nutrient reserves, and disrupting carbon and nitrogen cycles. Conventional input‑intensive agriculture has delivered yield gains but has also contributed to widespread micronutrient deficiencies, nutrient loading of waterways, soil [...]
Artificial Intelligence in Climate Science: A State-of-the-Art Review (2020–2025)
Published: 2025-07-15
Subjects: Computer Sciences, Earth Sciences, Environmental Sciences, Statistics and Probability
Climate change is intensifying extreme weather events and posing complex challenges to human and natural systems. In parallel, rapid advances in artificial intelligence (AI) and machine learning (ML) offer new tools to tackle climate science problems. AI can analyze vast climate datasets, improve forecasts, and optimize climate solutions at scales and speeds beyond traditional methods. For [...]
A Constraint-Convergent Framework for Tornado Formation (the ARCH Equation)
Published: 2025-07-15
Subjects: Physical Sciences and Mathematics
Despite significant advances in meteorological observation and modeling, the precise prediction of tornado occurrence remains a persistent challenge. Traditional forecasting approaches often rely on additive or probabilistic frameworks, assuming that the likelihood of a tornado increases as favorable parameters accumulate. However, many environments that appear highly conducive to tornadoes fail [...]
Ice dynamic and hydrological response to ice-dammed lake drainages at Isunnguata Sermia, West Greenland
Published: 2025-07-17
Subjects: Earth Sciences, Glaciology, Physical Sciences and Mathematics
Ice-marginal lakes are increasingly common around Greenland and are important for modulating glacier runoff and dynamics. This study investigates the evolution of a ~3 km2 and up to ~100 m deep ice-dammed lake at Isunnguata Sermia, West Greenland. Satellite observations between 1987 and 2024, and field observations of a 2023 drainage using passive seismics, GNSS and time-lapse imagery reveal that [...]
GEDIMetrics: a QGIS plugin for accessing and integrating multi-product GEDI spaceborne LiDAR data

NASA's Global Ecosystem Dynamics Investigation (GEDI) provides near-global, high-resolution 3D LiDAR observations of forest vertical structure. However, GEDI products are distributed as independent HDF5 files organised by beam, requiring ad-hoc workflows for data discovery, quality filtering, spatial subsetting, and footprint-level alignment across products. Existing tools either target a single [...]
