“…After about 80 kya, arid conditions set in until about 35 kya, or possibly earlier, when a new and prolonged phase of increased precipitation took over and extended until about 25-20 kya. These conditions were less wet than in the previous two phases, but were widespread throughout the Peninsula, and included the formation of extensive lakes in the Rub' alKhali (McClure, 1976) and in the Nafud region (Schultz and Whitney, 1986;Arz et al, 2003). Sanlaville attributes this episode to the southward movement of Mediterranean cyclones bringing winter rainfall.…”

“…An interesting feature of Holocene climate change in the Northern Hemisphere and between the eastern Mediterranean and South Asia in particular is its quasi-cyclic evolution in the multi-centennial band (Bond et al, 2001;Staubwasser et al, 2003;Arz et al, 2003;Wang et al, 2005;Lamy et al, 2006). This have been linked to solar radiation variability, although the mechanism through which the small solar changes propagate into the climate system remains unclear.…”

The precipitation climatology and the underlying climate mechanisms of the eastern Mediterranean, West Asia, and the Indian subcontinent are reviewed, with emphasis on upper and middle tropospheric flow in the subtropics and its steering of precipitation. Holocene climate change of the region is summarized from proxy records. The Indian monsoon weakened during the Holocene over its northernmost region, the Ganges and Indus catchments and the western Arabian Sea. Southern regions, the Indian Peninsula, do not show a reduction, but an increase of summer monsoon rain across the Holocene. The long-term trend towards drier conditions in the eastern Mediterranean can be linked to a regionally complex monsoon evolution. Abrupt climate change events, such as the widespread droughts around 8200, 5200 and 4200 cal yr BP, are suggested to be the result of altered subtropical upper-level flow over the eastern Mediterranean and Asia.The abrupt climate change events of the Holocene radically altered precipitation, fundamental for cereal agriculture, across the expanse of late prehistoric-early historic cultures known from the archaeological record in these regions. Social adaptations to reduced agro-production, in both dry-farming and irrigation agriculture regions, are visible in the archaeological record during each abrupt climate change event in West Asia. Chronological refinement, in both the paleoclimate and archaeological records, and transfer functions for both precipitation and agro-production are needed to understand precisely the evident causal linkages.

“…Though the planktic and benthic records are strikingly similar (Fig. 5C), we regard the benthic record as more reliable because the planktic data set is composed of three different species and may be biased by local changes in evaporation and precipitation (Arz et al, 2003a). For the calculation of our sea-level record , we consider two endmembers: In the first case, we assume that the full amplitude of surface water temperature changes penetrated to the deep basin and use the alkenone SST record (Fig.…”

Based on a radiocarbon and paleomagnetically dated sediment record from the northern Red Sea and the exceptional sensitivity of the regional changes in the oxygen isotope composition of sea water to the sea-level-dependent water exchange with the Indian Ocean, we provide a new global sea-level reconstruction spanning the last glacial period. The sea-level record has been extracted from the temperature-corrected benthic stable oxygen isotopes using coral-based sea-level data as constraints for the sea-level/oxygen isotope relationship. Although, the general features of this millennial-scale sea-level records have strong similarities to the rather symmetric and gradual Southern Hemisphere climate patterns, we observe, in constrast to previous findings, pronounced sea level rises of up to 25 m to generally correspond with Northern Hemisphere warmings as recorded in Greenland ice-core interstadial intervals whereas sea-level lowstands mostly occur during cold phases. Corroborated by CLIMBER-2 model results, the close connection of millennial-scale sealevel changes to Northern Hemisphere temperature variations indicates a primary climatic control on the mass balance of the major Northern Hemisphere ice sheets and does not require a considerable Antarctic contribution. r

Abstract: ognition of the potential for strong ground motions and the coseismic development of 1-to 2-m-high, Ͻ145-m-wide fold scarps associated with Mw Ն7 earthquakes on the PHT will help to refine seismic hazard plans and policies in this large metropolitan region.
