Holocene hydrological changes in Europe and the role of the North Atlantic ocean circulation from a speleothem perspective

Societal concerns about future hydroclimate changes urge a thorough understanding of the governing processes. Here, an analysis of Middle and Late Holocene speleothem-based hydroclimate reconstructions and paleoclimate model simulations reveals sub-millennial fluctuations in the spatiotemporal varia...
