Here, we use 7437 stable oxygen (δ 18 O) isotope ratios extracted from 192 living and relict Alpine trees to reconstruct trends extremes in European summer hydroclimate 8980 before the present 2014 Common Era. Our continuous tree-ring δ O record reveals a significant long-term drying trend over much of Holocene ( P < 0.001), which is line with orbital forcing independent evidence proxy reconstructions model simulations. Wetter conditions early-to-mid coincide African Humid Period, whereas most severe droughts past 9000 years are found during Little Ice Age 18th 19th centuries We suggest that Europe was not only warmer but also wetter preindustrial Holocene, implies close relationship between insolation changes likely affected natural societal systems across wide range spatiotemporal scales.

Introduction The interplay between cutture and environment in the Third Pole Region holds profound implications for region's socio-ecological resilience long-term sustainability. However, existing research has largely relied onisolated analyses, often constrained by absence of integrative frameworks capable capturing dynamic interdependent nature cultural environmental systems. These conventional approaches frequently overlook spatial-temporal complexity, synergistic relationships, feedback mechanisms intrinsic to this interplay, thereby limiting their predictive accuracy adaptability addressing emerging challenges. Methods To bridge these gaps, we propose Dynamic Cultural-Environmental Interaction Network (DCEN), a novel computational framework that integrates metrics variables within graph-based, multidimensional model. This approach systematically captures bidirectional interactions through coupled nonlinear equations, incorporating spatial temporal dynamics while accounting external stimuli abrupt perturbations. Furthermore, introduce Adaptive Strategy Cuttural-Environmental Systems (AIS-CES), which enables real-tme optimization model parameters based on system feedback, ensuring stability, adaptability, enhanced resilience. Results Experimental validation demonstrates proposed effectively simulates complex cultural-environmental with high accuracy, providing robust foundation policymaking, adaptive management, disaster mitigation Region. Discussion By critical limitations existng methodologies, advances more holistic actionable understanding dynamics, fostering regional sustainability harmony.

Abstract Tree ring‐based climate reconstructions are fundamental for high‐resolution paleoclimatology, but only a few of them extend back into the mid‐Holocene (8,200–4,200 years BP). Here, we present annually‐resolved tree‐ring stable carbon and oxygen isotopes (δ 13 C δ 18 O) from subfossil yew ( Taxus baccata ) wood excavated in Fenland region eastern England. We develop an eco‐physiological model to reconstruct hydroclimate variability 5,224 4,813 ± 4 4,612–4,195 6 cal. BP. Our findings suggest that relative sea‐level rise North Sea, riverine flooding, prolonged negative phase Atlantic Oscillation caused unusually wet conditions around 4,200 ago when woodlands England disappeared. expect our study stimulate isotope measurements relict encourage integration terrestrial marine proxy archives causes consequences large‐scale variations still debated 4.2 ka event.
