Tree‐Ring Stable Isotopes Reveal a Hydroclimate Shift in Eastern England Around 4.2 ka Ago
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 and δ 18 O) from subfossil yew ( Taxus baccata ) wood excavated in the Fenland region of eastern England. We develop an eco‐physiological model to reconstruct hydroclimate variability from 5,224 to 4,813 ± 4 and 4,612–4,195 ± 6 cal. years BP. Our findings suggest that a relative sea‐level rise in the North Sea, riverine flooding, and a prolonged negative phase of the North Atlantic Oscillation caused unusually wet conditions around 4,200 years ago when yew woodlands in eastern England disappeared. We expect our study to stimulate high‐resolution stable isotope measurements in relict wood and encourage the integration of terrestrial and marine proxy archives to reconstruct the causes and consequences of large‐scale climate variations around the still debated 4.2 ka event.
