Synergistic Convergence of Multiple Environmental Drivers Triggered a Multi‑taxa Regime Shift in the Yangtze Estuary

Based on two decades of multi-taxa and environmental data, this study reveals that the Yangtze Estuary underwent a fundamental regime shift around 2009–2010 driven not by a single factor but by the synergistic convergence of critical thresholds in dissolved oxygen, nutrients, and their ratios, providing essential reference points for ecosystem management.

The 1994 Mw 7.8 Sanriku-Haruka-Oki Earthquake and Complex Recurrence on a Weakly Segmented Megathrust

By integrating teleseismic, strong-motion, and GNSS data, this study reveals that the 1994 Mw 7.8 Sanriku-Haruka-Oki earthquake involved two distinct NW–SE aligned slip patches separated by a low-slip zone influenced by pre-existing structural heterogeneities, suggesting that such weak segmentation governs the complex recurrence patterns of large megathrust earthquakes in the region.

Climate warming shortens mast intervals by accelerating resource accumulation in the Northern Hemisphere

Based on an analysis of over 61,000 seed production records from 700 species across the Northern Hemisphere, this study demonstrates that climate warming shortens mast intervals by accelerating resource accumulation and lowering the cumulative resource thresholds required for reproductive events, with significant implications for forest regeneration and ecosystem dynamics.

Pre-Seismic Tectonic Strain Mapping via Spatiotemporal Quantum-Piezoelectric Resonance: A Humanitarian Pathway to Proactive Earthquake Forecasting

This paper presents a groundbreaking experimental framework utilizing room-temperature Piezoelectric-Quantum Interference (PQI) mapping and the J.M. Resonance Function to successfully forecast a magnitude 6.0 earthquake in the Japan Trench 12 hours in advance, demonstrating a viable pathway for proactive seismic disaster mitigation through efficient, edge-computing-based precursor detection.

Carbon release from Chatham Rise pockmarks may have been climatically relevant during the last deglaciation

This study uses a 2D hydromechanical model to demonstrate that rapid fluid release from Chatham Rise pockmarks during the last deglaciation could have emitted approximately 2 Petagrams of CO2 per year, a rate significantly higher than that of the Paleocene-Eocene Thermal Maximum, suggesting such geologic carbon release was a major, previously underappreciated driver of deglacial atmospheric CO2 trends.

EPC Mirage: Grid decarbonisation can overstate retrofit progress in carbon-weighted building energy ratings

This paper demonstrates that carbon-weighted building energy ratings can artificially inflate perceived retrofit progress by crediting grid decarbonization rather than physical building improvements, as evidenced by a UK policy change that triggered widespread rating upgrades without corresponding energy savings, prompting a call to separate carbon accounting from physical performance standards.

Effect of soils from forests and fire-deforested areas on sapling development of native tree species from a tropical montane forest

A controlled nursery experiment in Bolivia's tropical montane forest demonstrates that saplings of native tree species exhibit enhanced growth and leaf production in soils from recently burned, bracken-dominated areas due to elevated nutrient levels, suggesting that reforestation efforts should prioritize planting soon after fires rather than waiting for soil recovery.

Biodiversity evidence for integrative policy and collaborative governance: nexus mechanisms across climate, food, water, energy, transport and health

This study synthesizes evidence from 194 European studies to demonstrate that biodiversity acts as a dynamic nexus component linking climate, food, water, energy, transport, and health systems, arguing that effective governance must shift from fragmented sectoral approaches to integrative policies that amplify positive feedbacks and interrupt harmful cascades.

A Positive Feedback between Iceberg Calving and Local Sea Level through Hydrostatic Pressure

This study reveals a previously unexplored positive feedback mechanism where local sea level drops, caused by ice sheet mass loss, reduce hydrostatic pressure at calving fronts to accelerate further calving and ice loss, ultimately increasing projected ice sheet mass loss by 86% over 200 years and highlighting the necessity of coupling local sea level dynamics with calving processes in future projections.
