"A valid mixture of anxiety, despair, rage, grief": Canadian clinician perspectives on climate-related extreme weather impacts and mental health
Published: 2026-06-03
Subjects: Public Health
Climate change has been increasingly recognized as a determinant of mental health, yet limited research has examined how mental health care systems and clinicians are perceiving and responding to the impacts. This study explores the experiences of clinicians supporting people with mental health conditions in relation to climate change and extreme weather events (EWEs). We conducted a [...]
Microplastic deposition controlled by fluvial sedimentary facies in an urban river
Published: 2026-06-03
Subjects: Physical Sciences and Mathematics
Microplastic particles (MP) are characterised by their irregular shapes, lower density relative to natural grains, often failing at subscribing to sedimentological transport laws under controlled experimental conditions. Mismanagement of plastic waste, including associated environmental and health concerns, underpins the importance of systematic field-based behavioural observations on their [...]
Generation of Orientation-Independent Response Spectrum Matched Records Satisfying Minimum Fourier Amplitude and Power Spectral Density Requirements
Published: 2026-06-03
Subjects: Engineering
The seismic design and assessment of critical infrastructure, particularly within the nuclear industry, relies heavily on acceleration time histories compatible with a Design Response Spectrum (DRS). While current spectral matching algorithms effectively tune ground motions to match a target DRS, this process can inadvertently deplete the signal’s energy at specific frequencies, leading to [...]
Spatially and temporally dense measurements reveal meteorological driver of atmospheric mercury variability
Published: 2026-06-03
Subjects: Atmospheric Sciences
The environmental fate of mercury (Hg) is determined by its atmospheric processing, yet the relative role of surface fluxes, chemistry, and transport on atmospheric loadings remains poorly understood. We use multiyear gaseous elemental Hg (Hg0) concentration measurements at two rural sites and two urban sites in the northeastern US coordinated by the National Atmospheric Deposition Program (NADP) [...]

We present a reproducible pipeline for downloading, processing, and harmonising global temperature anomaly series from HadCRUT5, GISTEMP, NOAAGlobalTemp, Berkeley Earth, and ERA5. All datasets are aligned to a common 1850-1900 pre-industrial baseline to enable direct comparison. The workflow also integrates the Oceanic Niño Index (ONI) to annotate El Niño and La Niña phases in the figures, [...]
EARLY PLIOCENE DRAWDOWN AND EXPANSION OF THE ANTARCTIC PENINSULA ICE SHEET IN MARGUERITE BAY
Published: 2026-06-02
Subjects: Earth Sciences, Geochemistry, Glaciology, Sedimentology, Stratigraphy
The Antarctic Peninsula Ice Sheet (APIS) is situated in a rapidly and persistently warming region of Antarctica and its behavior under warmer conditions projected for Earth’s future remains poorly constrained. Interpretations of stratigraphic records of ice-sheet change from periods of warmth in Earth’s past are essential in providing boundary conditions for estimates of future ice loss and its [...]
Mineral stabilization of soil organic sulfur at the continental scale
Published: 2026-06-02
Subjects: Biogeochemistry, Life Sciences, Physical Sciences and Mathematics, Soil Science
Declining atmospheric sulfur (S) deposition makes S an emerging limiting macronutrient to plants, yet the stability and dynamics of soil organic S - the largest terrestrial S pool supplying plant-available sulfate via mineralization - remain unclear. Across North American soils, mineral-associated organic S (MAOS), a stabilized pool by mineral protection, dominates (61 ± 26% of the total soil S) [...]
Was there an ocean between the North China-Qaidam and Tarim blocks connecting the Mongol-Okhotsk and Paleo-Tethys oceans?
Published: 2026-06-02
Subjects: Earth Sciences, Geology, Tectonics and Structure
The tectonic history of the final amalgamation of Eurasia is puzzling: geological and paleomagnetic data yield contrasting interpretations. Paleomagnetism shows that the North China Block and the Qaidam Basin fragment, migrated northward by several thousand kilometers relative to Eurasia until the latest Jurassic-Early Cretaceous. If true, plate tectonic principles require that a North [...]
