Magnitude-order improvements to the measurement precision of Antarctic grounding zone dynamics using SAR satellite constellations
Published: 2026-09-04
Subjects: Aerospace Engineering, Earth Sciences, Engineering, Geophysics and Seismology, Glaciology
Glacier loss in Antarctica is strongly influenced by melt in the grounding zone, the transition between grounded and floating ice. Thwaites Glacier is a critical region, with 65 cm of sea-level-equivalent ice. A recent dataset tracks grounding line retreat for Thwaites and other Antarctic ice streams over 30 years. Despite this long-term record, significant uncertainty remains in predictions of [...]
Temporal leakage in annual satellite embeddings inflates landslide susceptibility assessments
Published: 2026-10-20
Subjects: Geomorphology
Annual satellite embeddings summarize a calendar year, so the layer for a landslide's event year can also record the event's aftermath. We quantified how this input timing biases susceptibility evaluation across 18 events and 61,402 landslide locations, changing only the input year while samples, spatial folds and models stayed fixed. Event-year AlphaEarth inputs raised within-event AUC by 0.0874 [...]
Seismic expression, structure and evolution of flow cells within a submarine landslide
Published: 2020-03-25
Subjects: Earth Sciences, Geology, Geomorphology, Physical Sciences and Mathematics, Sedimentology
Submarine landslides are not a singular mass of sediment, but may instead comprise shear zone-bound, intra-flow cells of different sizes, rheological states, and strains. Constraining their evolution is important for assessing risks to subaqueous infrastructure and coastal communities, yet controls on their initiation, translation, and cessation remain unclear. We here use five, high-quality [...]
A multicriteria decision analysis framework for generating baseline virtual weather stations in Zimbabwe
Published: 2026-09-04
Subjects: Oceanography and Atmospheric Sciences and Meteorology
In this study, we generate baseline Virtual Weather Stations (VWS) in locations with minimal atmospheric noise by avoiding two major surface factors known to cause noise in remotely sensed weather observations. The study also proposes an improvement to the spatial coverage of Zimbabwe's weather observation network through the identification of environmentally suitable locations for virtual [...]
Stokes flow in logarithmic-viscosity space: velocity renormalization and a reference-operator formulation
Published: 2026-08-13
Subjects: Fluid Dynamics, Physical Sciences and Mathematics, Planetary Geophysics and Seismology
Effective viscosity in crystalline solids commonly depends exponentially on temperature, pressure, composition and other state variables, producing spatial variations over many orders of magnitude and making variable-viscosity Stokes flow numerically demanding. We develop an exact, coordinate-independent reformulation using logarithmic viscosity \(\Lambda=\ln(\eta/\eta_0)\) and renormalized [...]
Competing Psychological Pathways Linking Age and Individual and Collective Pro-Environmental Behavior Intentions: The Role of Conservatism
Published: 2026-09-04
Subjects: Environmental Studies
Promoting pro-environmental behavior (PEB) across the lifespan is critical for achieving an effective response to climate change. This may particularly be important in later life, as older adults hold substantial economic resources and electoral influence, enabling them to shape societal responses to environmental challenges. However, they have also been found to be more likely than younger [...]
“It is a sham process with participation.” Ten forms of citizen participation for sustainable development in the Norwegian Arctic
Published: 2025-07-31
Subjects: Environmental Studies
Achieving the Sustainable Development Goals (SDGs) requires action at all levels, from local to global, through synergy among all societal actors. Norway shares responsibility for SDG-based sustainable development with local authorities (municipalities and counties). The Planning and Building Act’s purpose clause stipulates that it shall promote sustainable development for the benefit of [...]
Zooplankton DNA metabarcoding supports regional ocean acidification monitoring and identifies novel candidate bioindicators in the Southern California Bight
Published: 2026-05-16
Subjects: Oceanography and Atmospheric Sciences and Meteorology
The impacts of ocean acidification (OA) on marine communities are a growing concern for coastal upwelling ecosystems, such as the Southern California Bight (Bight). Successful management of coastal resources in the face of OA requires accurate assessment tools to understand the status and trends of OA impacts on biological communities. Current methods often rely on the condition of individual [...]
On the pattern, magnitude, and timing of anthropogenic heat uptake in the Southern Ocean
Published: 2026-10-01
Subjects: Atmospheric Sciences, Climate, Oceanography, Oceanography and Atmospheric Sciences and Meteorology
Most of the anthropogenic heat absorbed by the ocean enters through the Southern Ocean, yet the processes that set the pattern, magnitude, and timing of this uptake remain unclear. Using a climate model (CESM1) under abrupt 4xCO2, we show that uptake by the preindustrial ocean circulation alone accounts for more than half of the Southern Ocean uptake and reproduces its slow decline. We isolate [...]
Tectonic history of East Asia and the Asiana hypothesis
Published: 2026-10-09
Subjects: Physical Sciences and Mathematics
When almost all continents were assembled in the late Paleozoic supercontinent Pangea, East Asian continental blocks existed as distinct, separate entities. Ocean closures and stepwise assembly of these blocks into larger continents were the main paleogeographic changes to influence paleoclimate and biogeography during Pangea time. In this Perspective, we review how Triassic assembly of the East [...]
Abundance and Spatial Distribution of Third Generation Cephalosporin Resistant Escherichia coli in Wastewater and impact on the receiving Korle Lagoon, Accra, Ghana

Healthcare professionals (HCPs), as trusted cadre of community, play a crucial role advocating climate action to reduce its impact on health. This study aimed to assess the knowledge, attitudes, practices and perceived responsibilities (KAPP), associated factors, of healthcare providers in Karachi, Pakistan, regarding climate change and its associated health effects. We conducted a [...]
Hydroclimatic change reorganizes karst spring discharge in the Alpine region across discharge regimes and karst-system properties
Published: 2026-10-20
Subjects: Hydrology
Karst springs are important water resources for the Alpine region and are particularly sensitive to hydroclimatic change due to their comparably short response times. Yet how their hydroclimatic responses differ among discharge regimes and karst systems with different storage properties remains poorly understood. We analyzed 85 karst springs across the wider Alpine region over 2003-2022 to assess [...]
Bounded at both ends: the detection window of routine 12-day C-band InSAR at rock–ice avalanche sources
Published: 2026-09-14
Subjects: Earth Sciences, Geomorphology
A negative result from satellite radar — "no precursory deformation was detected" — carries no information unless the range of signals the measurement could have detected is reported alongside it. We measure that range at two rock–ice avalanche sources, Langtang Lirung, Nepal (2026) and Ronti Peak, India (2021), using a single procedure, and identify four determinants of it that are site-specific [...]
Sub-pixel mapping of annual tree and standing deadwood cover from Sentinel-2 time series across the globe
Published: 2026-02-24
Subjects: Artificial Intelligence and Robotics, Biogeochemistry, Computer Sciences, Earth Sciences, Engineering, Environmental Monitoring, Environmental Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics
Elevated forest disturbances and excess tree mortality are increasingly reported worldwide. Yet existing assessments are either based on patchy terrestrial observations or on large-scale satellite products, which are limited in resolution to pixel-level, binary tree loss detection. This leaves a blind spot on fine-scale disturbances where only a few trees are declining in an otherwise intact [...]
