Twelve pollen-inferred aridity major and minor events (S1 to S12) have been identified at Salines playa lake (SE Iberian Peninsula, 475 m asl, 38° 30′ 02″ N 00° 53′ 18″ W) from the Lateglacial to the Early Holocene (Boreal). These dry events consist of an increase in the aridity quotient calculated as a function of selected pollen taxa at 13.4, 13, 12.55, 12.2, 11.9, 11.45, 11, 10.6, 10.3, 10, 9.5 and 8.3 ka cal BP. These dry events correspond to the previous identified cold spells such as the Younger Dryas, as well as the 8, 7, 6 and 5 Bond events, and 11.4 and 9.3 events. This climate record highlights the complex glacial-interglacial transition in extra-tropical latitudes, with centennial-scale abrupt climate fluctuations, a signature scarcely recorded in other palaeoecological records of the SE Iberian Peninsula. This work has major implications for the study of human socio-ecological systems and resilience in SE Iberia during the Epipaleolithic and Mesolithic periods.
