Speleothem chronologies and model outputs for permafrost thaw studies across the Tibetan Plateau and Arctic

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.
