2026-08-12 Speleothem chronologies and model outputs for permafrost thaw studies across the Tibetan Plateau and Arctic doi:10.57760/sciencedb.39717 en A multi-component dataset has been compiled that integrates absolutely dated speleothem growth intervals with paired stable-isotope measurements and complementary numerical model outputs. The dataset comprises recalculated uranium–thorium ages and associated uncertainty estimate for speleothems from the Tibetan Plateau, East Siberia and western North America; linked δ18O and δ13C measurements for Tibetan Plateau speleothems; derived growth-frequency products; gridded outputs from coupled atmosphere–ocean equilibrium experiments and a North-Atlantic hosing perturbation; component fields from a climate-feedback–response decomposition. These resources are intended to facilitate independent phasing analyses, model–data comparisons, process attribution studies of teleconnections, and benchmarking of permafrost and carbon-cycle models.
