To optimize explained variance and sample replication, we combined MXD chronologies from opposite ends of the summer EU JSL dipole, with the trade-off that this approach constrained our ability to retain low-frequency variability (Methods). As such, our EU JSL reconstruction is dominated by inter-annual to multi-decadal-scale variability (Fig. 3b) and well-studied centennial-scale periods in European climate, such as the colder phases of the Little Ice Age33, do not emerge. Nevertheless, a multi-decadal southern EU JSL anomaly from 1810 to 1839 ce overlaps with the cold early-nineteenth-century end phase of the Little Ice Age. The years 1813–1816 ce in particular, the southernmost EU JSL years on record, coincide with the eruptions of the tropical Mayon (1814 ce) and Tambora (1815 ce) volcanoes34, suggesting a potential link between EU JSL position and volcanic activity that could have exacerbated the cold summer temperatures in NEMED.
