Global agricultural shocks from Atlantic overturning collapse

This study reveals that a collapse of the Atlantic Meridional Overturning Circulation (AMOC) would trigger a 5.3% global decline in major crop production, disproportionately devastating Northern Hemisphere export hubs and potentially causing a 40% structural spike in global cereal prices due to severe trade network disruptions.

National Borders Impede Collaboration on Climate Adaptation, Yet Conducive Factors Exist: A New Framework and Network-Analytical Evidence

This study analyzes the Danish-German border region to demonstrate that while national borders hinder climate adaptation collaboration, the use of a common language and systemic incentives for cooperation significantly enhance cross-border ties, offering a new framework for understanding joint climate responses.

Probability Distributions and Return Periods of Extreme Rainfall Events in the Zagros Mountains: Karkheh Basin Floods

This study analyzes the statistical characteristics and return periods of extreme rainfall in Iran's Karkheh River Basin, revealing an increasing trend in maximum daily rainfall and estimating that the severe March 2019 floods at Poldokhtar and Nurabad stations had return periods ranging from 70 to 200 years based on Gumbel and Inverse Gamma distributions.

Flood Detection and Cropland Damage Assessment Using Sentinel-1 SAR Time Series Multi-Source EO Data in the Sebou Basin, El Gharb plain, Morocco

This study utilizes Sentinel-1 SAR time series data with VV and VH polarizations to develop a robust, anomaly-based flood detection method that effectively maps inundation and assesses cropland damage in Morocco's Sebou Basin, ultimately informing targeted risk management strategies for the El Gharb plain.

Climate in a Single-Entrance Cave Controlled by Buoyancy-Driven Counterflow and Thermal Inertia

This study demonstrates that ventilation in single-entrance karst caves is governed by buoyancy-driven bidirectional counterflow during cold periods and is significantly modulated by the thermal inertia of the surrounding rock and sediments, which sustains airflow and alters responses to subsequent cooling events.

Early Miocene small mammals from Harta 2 (western Anatolia) and their implications for systematics and biostratigraphy

The newly discovered Early Miocene small mammal assemblage from Harta 2 in western Anatolia, dominated by rodents and assigned to local zone D (MN3), provides critical data for refining the region's biochronology, extending the stratigraphic range of *Vasseuromys duplex*, and reconstructing subhumid paleoenvironmental conditions.

No directional change in local vascular plant communities from 2007 to 2022 in Kangerluarsunnguaq (Southwest Greenland)

Despite evidence of large-scale vegetation shifts across the Arctic, a 15-year study of vascular plant communities in Southwest Greenland revealed no significant directional changes in diversity, composition, or functional groups at the local scale, highlighting the critical importance of long-term, fine-grained monitoring to capture ecosystem-specific dynamics.
