The role of shipping capacity and maritime regulation in ocean liming deployment

This paper integrates ocean liming into the WITCH Integrated Assessment Model to demonstrate that its deployment as a carbon dioxide removal method is highly dependent on maritime shipping capacity, port availability, and low-carbon fuel regulations, potentially contributing 9–15% of total CDR by the end of the century.

Long-Term Changes in Heatwave-Ozone Compound Events and Spatially Heterogeneous Ozone Associations across China

This study reveals that from 2000 to 2024, China experienced a significant nationwide increase in heatwave-ozone compound events—particularly nighttime and compound day-night heatwaves—with pronounced spatial heterogeneity in ozone sensitivity and expanding pollution hotspots, highlighting the urgent need for integrated climate adaptation and air-quality management strategies.

Cascading Hazards, Contested Futures: Media Analysis of the 2025 Blatten Disaster in the Swiss Alps

This study analyzes Swiss media coverage of the 2025 Blatten ice-rock avalanche disaster, revealing how the event was framed not only as a cascading natural hazard but also as a catalyst for broader societal debates on climate change adaptation, governance, and the future habitability of Alpine communities.

Long-term Radiosonde Observations from Ny-Ålesund Reveal Shifts in Temperature Trends over Svalbard Linked to Atmospheric Circulation Changes

A 33-year homogenized radiosonde record from Ny-Ålesund reveals that Arctic warming over Svalbard exhibits strong seasonal and decadal variability, where shifts in atmospheric circulation patterns—such as the transition from southerly warm-air advection to northerly flows—have decoupled free-tropospheric temperature trends from surface warming, leading to recent winter stagnation and autumn intensification.

Comparative Analysis of Chernozem Microbiome Resistance to Toxic Heavy Metals (Co²⁺, Cu²⁺, Zn²⁺, Ni²⁺) under Individual and Pairwise Exposure

This study demonstrates that while the native chernozem microbiome exhibits varying resistance to individual heavy metals (Co²⁺, Ni²⁺, Zn²⁺, Cu²⁺), binary mixtures induce severe synergistic toxicity that drastically exceeds additive predictions, revealing that current single-metal risk assessments critically underestimate the hazards of polymetallic contamination.

Biodegradable microplastic type and wheat-straw addition shape soil CO₂ emissions: links to dissolved organic matter turnover and microbial carbon allocation

This study demonstrates that biodegradable microplastics and wheat straw addition significantly alter soil CO₂ emissions through complex interactions involving dissolved organic matter turnover and microbial carbon allocation, revealing that increased respiration does not necessarily correlate with higher dissolved organic carbon concentrations, gene abundance per cell, or total tracer assimilation.
