Fingerprints of Holocene climate on the functional trait diversity of Arctic marine biota

By analyzing an 8,300-year marine sedimentary ancient DNA record from the high Arctic, this study reveals how Holocene climate variability and the Arctic Oscillation drove heterogeneous functional trait diversity and temperature-size trade-offs in marine biota, offering unprecedented insights into ecosystem resilience across millennial timescales.

Spatiotemporal Patterns and Trends of the Holiday Climate Index Along the Black Sea Coastal Zone of Türkiye (1950–2025)

This study presents the first comprehensive long-term assessment (1950–2025) of tourism climate suitability along Türkiye's Black Sea coast using a novel weighted Holiday Climate Index, revealing that while summer conditions remain stable, climate change is significantly extending favorable tourism windows into spring and autumn, with improvements being more pronounced in the western provinces than in the humid east.

Disentangling Natural Mineralization from Nitrate Pollution in a Semi-Arid Alluvial Aquifer: A Log-Transformation-Based Multivariate and GIS Framework (Tébessa-Morsott Basin, Algeria)

This study employs a log-transformation-based multivariate and GIS framework on multi-temporal data from the Tébessa-Morsott Basin to successfully distinguish between natural geogenic mineralization driven by carbonate and evaporite dissolution and anthropogenic nitrate pollution caused by agricultural and wastewater inputs in a semi-arid alluvial aquifer.

Deep-learning climate emulator ACE2 reveals a global decrease in tropical cyclone frequency in the 15th Century under an El Niño-like sea surface temperature pattern

Using the deep-learning-based ACE2 emulator, this study reveals that an El Niño-like sea surface temperature pattern in the 15th Century drove a global decrease in tropical cyclone frequency through enhanced vertical wind shear and a drier midtroposphere, thereby demonstrating the utility of deep learning in paleoclimate analysis to improve future projections.
