Zusammenfassung |
A combination of marine (Alboran Sea cores, ODP 976 and TTR 300 G) and
terrestrial (Zoñar Lake, Andalucia, Spain) geochemical proxies provides
a high-resolution reconstruction of climate variability and human influence
in the southwestern Mediterranean region for the last 4000 years at
inter-centennial resolution. Proxies respond to changes in precipitation
rather than temperature alone. Our combined terrestrial and marine archive
documents a succession of dry and wet periods coherent with the North
Atlantic climate signal. A dry period occurred prior to 2.7 cal ka BP –
synchronously to the global aridity crisis of the third-millennium BC – and
during the Medieval Climate Anomaly (1.4–0.7 cal ka BP). Wetter conditions
prevailed from 2.7 to 1.4 cal ka BP. Hydrological signatures during the
Little Ice Age are highly variable but consistent with more humidity than
the Medieval Climate Anomaly. Additionally, Pb anomalies in sediments at the
end of the Bronze Age suggest anthropogenic pollution earlier than the Roman
Empire development in the Iberian Peninsula. The Late Holocene climate evolution of
the in the study area confirms the see-saw pattern between the
eastern and western Mediterranean regions and the higher influence of the
North Atlantic dynamics in the western Mediterranean. |
