Palaeoclimate Reconstruction in the Levant and on the Balkans Spatial

For an understanding of the climate system’s variability, knowledge of the past climate is essential. Continuous observations are not available for longer than the last 100 years, a period that is insufficient to understand the variability and sensitivity of the climate system. Since information of both is necessary to build good climate models, the reconstruction of the past climate is fundamental. With palaeoclimate reconstructions it is possible to get information about the past climate and the climate...

Climate-Driven Ecosystem Succession in the Sahara: The Past 6000 Years doi Spatial

Desiccation of the Sahara since the middle Holocene has eradicated all but a few natural archives recording its transition from a “green Sahara” to the present hyperarid desert. Our continuous 6000-year paleoenvironmental reconstruction from northern Chad shows progressive drying of the regional terrestrial ecosystem in response to weakening insolation forcing of the African monsoon and abrupt hydrological change in the local aquatic ecosystem controlled by site-specific thresholds. Strong reductions...

Reconstruction of late Glacial and Early Holocene near surface temperature anomalies in Europe and their statistical interpretation doi Spatial

This paper presents the results of a variational analysis study based on the recently developed method by Gebhardt et al. to reconstruct paleo temperature fields on the typical scale of climate model output, providing the necessary basis for quantitative comparison of reconstructions and model results. Additionally, an extension of the approach takes into account the full statistics of the analysis error of the variational analysis to study the inherent uncertainties of the proxy data representing the...

Holocene climate variability in the Levant from the Dead Sea pollen record doi Spatial

The Dead Sea, located at the deepest place on continent and between the subtropical Mediterranean zone and the desert, reflects in its water composition and levels, and sedimentary records the hydrological conditions in the southern Levant region. Temporal variations in rainfall and temperatures of the Holocene Levant are reconstructed here from pollen data recovered from a sediment core drilled at the Ein Gedi shore, applying a novel biome model based on Bayesian statistics. Our results suggest that the...

Climate change recorded in the sediments of Chew Bahir, southern Ethiopia, during the last 45,000 years Spatial

East African paleoenvironments are highly variable, marked by extreme fluctuations in moisture availability, which has far-reaching implications for the origin, evolution and dispersal of Homo sapiens in and beyond the region. This paper presents results from a pilot core from the Chew Bahir basin in southern Ethiopia that records the climatic history of the past 45 ka, with emphasis on the African Humid Period (AHP, ∼15–5 ka calBP). Geochemical, physical and biological indicators show that Chew Bahir...
