Carpatian Basin 30ky bp GIS data set SFB806 doi Spatial

To provide paleoenvironmental data for a GIS and geostatistic based Species Distribution Modelling (SDM) application, this comprehensive GIS data set was created. The data set consists of DEM based topography, and of paleoclimate layers, that were used as environmental predictor variables for SDM application.

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...

Three climatic cycles recorded in a loess-paleosol sequence at Semlac (Romania) – implications for dust accumulation in south-eastern Europe doi Spatial

Recent investigations of the Semlac loess section in the south-eastern Carpathian Basin, which is situated at an undercut slope position on the right bank of the Mureş River in its lower reaches (Banat region, western Romanian), are presented and discussed. Dating back to marine isotope stage (MIS) 10, the more than 10 m thick loess sequence includes four fossil soil-complexes developed in homogenous and relatively fine silty loess. Because of the good preservation of the sediment, Semlac is regarded as a...

North-south palaeohydrological contrasts in the central Mediterranean during the Holocene: tentative synthesis and working hypotheses doi Spatial

On the basis of a multi-proxy approach and a strategy combining lacustrine and marine records along a north–south transect, data collected in the central Mediterranean within the framework of a collaborative project have led to reconstruction of high-resolution and well-dated palaeohydrological records and to assessment of their spatial and temporal coherency. Contrasting patterns of palaeohydrological changes have been evidenced in the central Mediterranean south (north) of around 40° N of latitude, the...

Köppen-Geiger classifications of paleoclimate model simulations (Presentation)

The development and application of an algorithm to compute the Köppen-Geiger climate classification for CMIP/PMIP climate model data is described in this persentation. The classification algorithm is applied to data from the PMIP III paleoclimate experiments for the Last Glacial Maximum (21k yBP), Mid-Holocene (6k yBP) and the Pre-Industrial (0k yBP, control run) time slices. The input data was interpolated to infer higher resolution classification maps. The classification was implemented using Open Source...

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...

Climatic change recorded in the sediments of the Chew Bahir basin, 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, w15e5 ka calBP). Geochemical, physical and biological indicators show that Chew Bahir...

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...
