Isotopes, trace elements and U-Th dates of Pyrenean stalagmites covering last 2500 years M. Bartolomé and A. Moreno https://doi.org/10.5281/zenodo.10563468
Short summary
Reconstructing past temperatures at regional scales during the Common Era is necessary to place the current warming in the context of natural climate variability. We present a climate reconstruction based on eight stalagmites from four caves in the Pyrenees, NE Spain. These stalagmites were dated precisely and analysed for their oxygen isotopes, which appear dominated by temperature changes. Solar variability and major volcanic eruptions are the two main drivers of observed climate variability.
