Climate and environmental evolution in the Huola Basin of the Mohe permafrost region, Northeast China, since late MIS 3

By analyzing a 4.15-meter sediment core from the Huola Basin using multi-proxy methods and dating techniques, this study reconstructs the last 30,000 years of climatic and environmental evolution in Northeast China's permafrost region, revealing four distinct stages of vegetation and climate change driven by global ice-volume fluctuations, the East Asian summer monsoon, and local permafrost-vegetation feedbacks.

Defining Topological Weather Regimes through Persistent Homology

This paper redefines Topological Weather Regimes as specific parts of chaotic attractors identified through zeroth- or first-order persistent homology based on point density, demonstrating that this topological approach yields results consistent with traditional statistical clustering methods when applied to South- and North-Atlantic jet datasets.

Urban archetypes reveal disparities in green cooling efficacy, residential access, and distributional equity across Singapore

By applying an urban archetype framework to Singapore's residential data, this study reveals that green cooling efficacy does not uniformly translate into accessible or equitable thermal relief, exposing significant disparities in service distribution and need-service mismatches across different housing types and environmental contexts.

Wind Damping of Internal Tides in the Global Ocean

This study demonstrates that wind forcing exerts a systematic damping effect on internal tides globally, contributing a net energy loss of 15 GW and accounting for approximately 4% of their total energy sinks, thereby necessitating the inclusion of wind work in internal tide energy budgets.

North Pacific surface warming pattern shaped by atmospheric responses and radiative feedbacks

This study reveals that North Pacific surface warming is primarily driven by forced atmospheric responses and clear-sky radiative feedbacks rather than coupled air-sea interactions, distinguishing its formation mechanism from that of the South Pacific.

Mercury in Amazonian fish: chemical speciation, environmental drivers and implications for food security and human health: a 36-year scientometric review

This 36-year scientometric review of 98 studies reveals a rising trend in research on mercury contamination in Amazonian fish, highlighting that while most investigations focus on inorganic mercury, a significant portion of piscivorous species in Brazil exceed WHO safety limits, posing severe risks to the food security and health of riverine and Indigenous communities.

Reading Climate in Wood: A Systematic Review of Dendro-Anatomical Proxies for Climate Reconstruction, Forest Health, and Sustainable Forest Management

This systematic review of 287 studies (1950–2026) demonstrates that integrating quantitative wood anatomical proxies with traditional dendrochronological methods significantly enhances the resolution and accuracy of climate reconstruction, forest health assessment, and sustainable management strategies, while highlighting the need for standardized multi-proxy approaches and expanded research in tropical and African forests.

No Common Yardstick: An Accuracy Classification for Planetary Control Networks

This paper proposes a new five-tier Planetary Control Network (PCN) accuracy classification system, adapted from terrestrial standards, to address the current lack of a common framework for reporting and comparing the horizontal positional accuracy of planetary spatial products.
