et al. # a comprehensive database of paleoclimate records is needed to place recent warming into the longer-term context of natural climate variability. We present a global compilation of quality-controlled, published, temperature-sensitive proxy records extending back 12,000 years through the Holocene. Data were compiled from 679 sites where time series cover at least 4000 years, are resolved at sub-millennial scale (median spacing of 400 years or finer) and have at least one age control point every 3000 years, with cutoff values slackened in datasparse regions. The data derive from lake sediment (51%), marine sediment (31%), peat (11%), glacier ice (3%), and other natural archives. The database contains 1319 records, including 157 from the Southern Hemisphere. the multi-proxy database comprises paleotemperature time series based on ecological assemblages, as well as biophysical and geochemical indicators that reflect mean annual or seasonal temperatures, as encoded in the database. This database can be used to reconstruct the spatiotemporal evolution of Holocene temperature at global to regional scales, and is publicly available in Linked Paleo Data (LiPD) format.
Records of past climate variability and associated vegetation response exist in various regions throughout Central and Eastern Europe (CEE). To date, there has been no coherent synthesis of the existing palaeo-records. During an INTIMATE meeting (Cluj Napoca, Romania) focused on identifying CEE paleo-records, it was decided to address this gap by presenting the palaeo-community with a compilation of high-quality climatic and vegetation records for the past 60-8 kyrs. The compilation should also serve as a reference point for the use in the modelling community working towards the INTIMATE project goals, and in data-model inter-comparison studies. This paper is therefore a compilation of up to date, best available quantitative and semi-quantitative records of past climate and biotic response from CEE covering this period. It first presents the proxy and archive used. Speleothems and loess mainly provide the evidences available for the 60-20 ka interval, whereas pollen records provide the main source of information for the Lateglacial and Holocene. It then examines the temporal and spatial patterns of climate variability inferred from different proxies, the temporal and spatial magnitude of the vegetation responses inferred from pollen records and highlights differences and similarities between proxies and sub-regions and the possible mechanisms behind this variability. Finally, it identifies weakness in the proxies and archives and their geographical distribution. This exercise also provides an opportunity to reflect on the status of research in the area and to identify future critical areas and subjects of research.
The paper presents the results of a palaeoecological study of Neolithic archaeological layers from a wetland, multilayer site, Serteya II (Western Russia). It contains, domestic structures, rich organic artefacts, skeletons, and ecofacts preserved within lacustrine deposits that are extremely important on a European scale. We employed a set of specialised palaeoecological analyses and accelerator mass spectrometry radiocarbon dating to identify the principal environmental conditions which attracted Neolithic hunter‐fisher‐gatherer communities from 4300 to 1600 cal. BC. The distinct impact of communities using a nonproductive economy on the ecology of the palaeolake shore zone was recorded. Also, palaeolake water level changes influenced the palaeoeconomic activity of local Neolithic societies, such as gathering of plants (for the medicinal use or serving as dietary components), fishing activities, and possible funeral practices. In addition, the identified phases of high‐water level changes, which were responses to climatic oscillations, were correlated with supraregional climatic events, especially ca. 6.2, 5.9, and 4.2 ka cal. BP. Thus, our results allowed for the reconstruction of environment transformations and conditions of Neolithic communities' activity, as well as for a better understanding of the relationships between local Neolithic communities' way of life and neolithisation processes in Eastern Europe.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
