Recent studies project a 20% decrease in precipitation by the end of this century compared to the 20th century. Therefore, high-resolution paleoclimate data are needed to develop robust future climate projections and modeling studies for the Eastern Mediterranean. This study investigates the mid-to-late Holocene paleoclimatic shifts and their impacts on civilizations in the Eastern Mediterranean using high-resolution isotope records from the Dim-3 stalagmite (Dim Cave, southern Türkiye). A precise and robust age–depth model was constructed using 23 U/Th dating results, spanning from 4149 to 996 years (yr) BP. The isotope results show the driest conditions occurring at 3986 yr BP, with a rapid shift to wetter conditions after 3890 yr BP. These wetter conditions were followed by a prolonged dry period from 3280 to 2720 yr BP. A subsequent wet period between 2720 and 2228 yr BP was interrupted by a 698-year growth hiatus in the stalagmite. In the final section of the record (1530–972 yr BP), initially wet climatic conditions transitioned to drier periods around 1425 yr BP and again between 1150 and 1075 yr BP. The Dim-3 isotope record shows enriched isotopic values between 4140 and 3890 yr BP, coinciding with the “4.2 ka drying event.” While a brief humid period was observed between 3050 and 2920 yr BP, the overall isotope values show an enriched trend from 3250 to 2800 yr BP, indicating the imprint of the 3.2 ka and Bond 2 events.</p>\u0000 </div>","PeriodicalId":16929,"journal":{"name":"Journal of Quaternary Science","volume":"41 1","pages":"61-79"},"PeriodicalIF":2.2,"publicationDate":"2025-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145970139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the climatic sensitivity of the region, relatively few studies have examined how conditions have varied since the last deglaciation in response to significant changes in global boundary conditions. Here, we present a 30 000-year sedimentary record from a coastal wetland at Pearly Beach on the southern Cape coast, focusing on climatic changes that occurred during the last glacial–interglacial transition. Downcore variations in grain size and inorganic geochemical composition provide evidence for a period of heightened storm activity between ~18.5 and 14.0 cal ka BP, which we interpret to reflect intensified westerly wind-driven activity. This period of increased storminess coincides with a slowdown in Atlantic meridional overturning circulation (AMOC) during Heinrich Stadial 1 (HS1: ∼18–14.6 ka) and subsequent warming in the southeast Atlantic Ocean. We propose that this warming enhances moisture uptake by westerly frontal systems, leading to stronger storms in the southern Cape.

In order to identify patterns associated with this type of environment, a series of LGM fossil specimens was selected from central Argentina, an area mantled by widespread eolian deposits. A combination of petrographic and scanning electron microscopy observations was employed, along with mineralogical (X-ray diffraction, XRD) and elemental chemical composition (energy-dispersive spectroscopy, EDS) analyses.

How much of this erosion is “natural”, and how much has it accelerated due to human action? More than a century ago, Sherlock (<span>1922</span>) claimed that the amount of sediment moved by humankind exceeded that of any other geomorphic agent. But was he right? The question has been much debated in the years since then (Hooke, <span>2000</span>; Syvitski et al., <span>2005</span>; Wilkinson, <span>2005</span>; Giosan et al., <span>2017</span>). Alongside numerical modelling, two principal empirical approaches have been adopted in attempts to answer this question. The first involves the measurement of contemporary rates of sediment flux (i.e., sediment transport) via different agencies. Flux of sediment reflects landscape stability and instability, whether of climatic, tectonic or human origin, or some combination. Transporting agencies include glacier ice and the wind (mainly aeolian dust), but globally, the dominant means of sediment movement from land to sea is via rivers, as suspended or dissolved load (Gibbs, <span>1970</span>; Douglas, <span>1990</span>; Milliman,<span>1990</span>). Studies have ranged in spatial scale from measurement of experimental soil erosion plots under different land cover types (e.g., Rapp, <span>1975</span>), through small catchment monitoring (Boardman et al., <span>1990</span>), to analysis of sediment discharge from major river basins like the Yangtse and Ganges (Walling and Webb, <span>1983</span>; Summerfield and Hulton, <span>1994</span>). The alternative approach is historical, commonly involving the examination of sedimentary “archives” in lakes, river valleys and estuaries to establish longer-term rates of change. The papers in this joint virtual special issue (VSI) of Geoarchaeology and <i>Journal of Quaternary Science</i> adopt this second strategy via a series of empirical-historical case studies that cover a range of different environments and timescales (Table 1). It is an approach based on the assumption that at some point in the past, human impact on erosion rates was minimal relative to natural agencies, and that this provides a baseline for assessing any subsequent increase of anthropogenic causation. In regions such as Europe and South Asia, this baseline is believed to date to mid-Holocene times, whereas it continued into the late Holocene in areas such as temperate North America (van Vliet-Lanoë et al., <span>1992</span>; Dearing and Jones, <span>2003</span>; Hoffmann et al., <span>2010</span>).</p><p>While a shared theme underpins this joint special issue, that of soil erosion, and the study of the complex interplay between climate and anthropogenic mechanisms, the allocation or “badging” of articles as either Geoarchaeology or Journal of Quaternary Science was based on the extent to which colleagues explicitly engaged with archaeological phenomena in their studies.

While this has been inferred from numerous locations, data from K'gari (a subtropical sand island adjacent to the east coast) was amongst the first used to develop this hypothesis and features heavily in the discussion of ENSO intensification.

This contrasts somewhat with previous arguments about K'gari's history that suggest a late Holocene drying.
