In this paper, we reconstruct late Holocene climate through a high-resolution multiproxy analysis of a sediment core from Lake Ocelo, a high elevation lake. Analysis of sedimentological, geochemical, and biological proxies reveal regional hydroclimatic variability over the past three millennia, and allow the identification of climate phases that reflect the complex interplay between Atlantic and Mediterranean influences. The Subatlantic Period (c. 890–200 BCE) marks a transition to wetter conditions after the 2.8 ka climate event. The Roman Warm Period (c. 200 BCE–300 CE) shows increased aridity, suggesting an expansion of Mediterranean influence, and the wetter Dark Ages Period (c. 300–750 CE) indicates renewed Atlantic dominance. The drier Medieval Climate Anomaly (c. 750–1100 CE) reflects greater Mediterranean influence. The transition from the Medieval Climate Anomaly to the Little Ice Age (c. 1100–1300 CE), defined as a distinct climatic phase, marks a shift to wetter conditions. The Little Ice Age (c. 1300–1900 CE) exhibits alternating wet-dry subphases and prolonged ice cover, leading to stronger denitrification under a stronger regional Atlantic influence. The Industrial Era (c. 1850 CE–present) is characterized by a warming trend, increased lake productivity, and reduced terrigenous input. These findings highlight the sensitivity of the Atlantic–Mediterranean ecotonal boundary to climate shifts and provide insights for predicting future dynamics, including potential “Mediterraneanization” of the Atlantic zoneThis work is supported by Grants PID2019-107424RB-I00 and PID2022-139775OB-I00 funded by MCIN/AEI/10.13039/501100011033, with the latter also co-funded by “ERDF A way of making Europe”.
