Unraveling the sequence of events and feedbacks at Termination III (T-III), including potential abrupt climate reversals similar to those of the last Termination, has been particularly challenging due to the scarcity of well-dated records worldwide. Here, we present speleothem data from southern Europe covering the interval from 262.7 to 217.9 kyBP, including the transition from marine isotope stage (MIS) 8 to MIS 7e. High-resolution d13C, d18O, and Mg/Ca profiles reveal major millennial-scale changes in aridity manifested in changing water availability and vegetation productivity. uranium-thorium dates provide a solid chronology for two millennial-scale events (S8.1 and S8.2) which, compared with the last two terminations, has some common features with Heinrich 1 and Heinrich 2 in Termination I (T-I). #------------------ # Funding_Agency # Funding_Agency_Name: Diputación General de Aragón (DGA), Ministerio de Economía (Gobierno de España) # Grant: Predoctoral grant, CGL2016-77479-R, CTM2013-48639-C2-2-R #------------------ # Site_Information # Site_Name: Ejulve Cave # Location: Europe>Southern Europe>Spain # Country: Spain # Northernmost_Latitude: 40.7594 # Southernmost_Latitude: 40.7594 # Easternmost_Longitude: -0.5853 # Westernmost_Longitude: -0.5853 # Elevation: 1240 m #------------------ # Data_Collection # Collection_Name: Ejulve2017ARTEMISA # Earliest_Year: 257426 # Most_Recent_Year: 218926 # Time_Unit: Cal.
