“…A similar effect may occur with significant increases in the relative inflow of more northerly rivers, such as the Upper Angara and Barguzin Rivers, given modern δ 18 Oriver compositions that are 4-6‰ lower than those for the Selenga River (Seal and Shanks, 1998 is notable that results are broadly comparable to patterns of effective summer precipitation obtained from a low-resolution regional general circulation model (Bush, 2005). Pollen precipitation reconstructions from both Lake Baikal and Lake Kotokel display similar trends to one another through the Holocene (Tarasov et al, 2007(Tarasov et al, , 2009) with the divergence away from δ 18 Odiatom precipitation emerging after c. 7 ka, when pollen precipitation decreases by c. 10% with no corresponding change in δ 18 Odiatom precipitation (Fig. 7).…”

“…Although it is beyond the remit of this study to evaluate the robustness of the pollen reconstructions, it is suggested that existing pollen records from Lake Baikal and Lake Kotokel (Tarasov et al, 2007(Tarasov et al, , 2009) may reflect localised, site-specific, changes in precipitation. In contrast, given the size of Lake Baikal's catchment (540,000 km 2 ) and with 83% of riverine inflow originating from the Selenga River and its tributaries, which extend into Mongolia, or the Upper Angara and Barguzin Rivers, which drain the region immediately to the east and north of Lake Baikal (Fig.…”

“…1), we propose that our δ 18 Odiatom precipitation record from Lake Baikal reflects an amalgamated average of conditions across the wider Central Asian region incorporating the lake's catchment. If correct, this interpretation suggests that whilst pollen records indicate drier conditions immediately around Lake Baikal in the mid/late Holocene (Tarasov et al, 2007(Tarasov et al, , 2009, the higher δ 18 Odiatom records imply that long-term trends in precipitation elsewhere in the catchment and in particular to the south of the lake remained relatively constant between the early/late Holocene period, trends that are supported by individual records from northern Mongolian (Wang and Feng, With a relationship established between δ 18 Odiatom and regional Central Asian precipitation around Lake Baikal, records of precipitation from the lake have the potential to aid the development of future forecasts for the region. Models in the Coupled Model Intercomparison Project (CMIP5) are currently not able to confidently predict future changes in Central Asian precipitation (Christensen et al, 2013), but together with regional models they indicate the potential for decreases in precipitation for northern Mongolia and the Lake Baikal catchment, leading to associated reductions in soil moisture and increased vulnerability to drought and fire (Sato et al, 2007;Törnqvist et al, 2014).…”

“…The δ 18 Odiatom reconstructed precipitation is also unlikely to be affected by Holocene changes in air temperature due to: 1) its negligible impact on δinflux and δ 18 Odiatom (Section 3.5); and 2) pollen derived reconstructions from both Lake Kotokel and the north basin of Lake Baikal that display "warmest month" temperature variations of only 2 o C throug the Holocene (Tarasov et al, 2007(Tarasov et al, , 2009). The δ 18 Odiatom/precipitation calibration assumes that both the moisture source region and the relative contribution of rivers flowing into Lake Baikal together with their seasonality has not significantly altered through the Holocene.…”

Climate models currently provide conflicting predictions of future climate change across Central Asia. With concern over the potential for a change in water availability to impact communities and ecosystems across the region, an understanding of historical trends in precipitation is required to aid model development and assess the vulnerability of the region to future changes in the hydroclimate. Here we present a record from Lake Baikal, located in the southern Siberian region of central Asia close to the Mongolian border, which demonstrates a relationship between the oxygen isotope composition of diatom silica (δ 18 Odiatom) and precipitation to the region over the 20 th and 21 st Century. From this, we suggest that annual rates of precipitation in recent times are at their lowest for the past 10,000 years and identify significant long-term variations in precipitation throughout the early to late Holocene interval. Based on comparisons to other regional records, these trends are suggested to reflect conditions across the wider Central Asian region around Lake Baikal and highlight the potential for further changes in precipitation with future climate change.

(250 words)While substantial progress has been achieved in hunter-gatherer research over the last century, it is still the case that our understanding of the cultural dynamism, variability, and resilience of Holocene hunter-gatherers remains rather impoverished. Emerging archaeological insights suggest that the prehistory of many forager societies included periods of sudden cultural transformation, marked by major shifts in subsistence strategies, settlement patterns and associated social life. Recent theoretical and methodological advances are enabling archaeologists to reconstruct the cultural dynamics of Holocene hunter-gatherers in an unprecedented degree of detail. This is especially true in regions that contain large prehistoric cemeteries, which can provide the base data for bioarchaeological reconstruction of individual life histories, shedding light on forager life-ways, their subsistence strategies and mobility patterns. Renewed attention is also being directed at the role of unstable environments and climate, which would have formed important contextual factors influencing how local cultural dynamics were played out. However, identifying explicit causal links between environmental instability and culture change remains empirically challenging. This paper investigates the major sequences of Holocene hunter-gatherer culture-change in two regions of Northeast Asia and details how the new Baikal-Hokkaido Archaeology Project will be researching the causal factors driving these cultural processes, including the possible role of climate and environment.

Quantitative information regarding the long‐term variability of precipitation and vegetation during the period covering both the Late Glacial and the Holocene on the Qinghai‐Tibetan Plateau (QTP) is scarce. Herein, we provide new and numerical reconstructions for annual mean precipitation (PANN) and vegetation history over the last 18,000 years using high‐resolution pollen data from Lakes Dalianhai and Qinghai on the northeastern QTP. Hitherto, five calibration techniques including weighted averaging, weighted average‐partial least squares regression, modern analogue technique, locally weighted weighted averaging regression, and maximum likelihood were first employed to construct robust inference models and to produce reliable PANN estimates on the QTP. The biomization method was applied for reconstructing the vegetation dynamics. The study area was dominated by steppe and characterized with a highly variable, relatively dry climate at ~18,000–11,000 cal years B.P. PANN increased since the early Holocene, obtained a maximum at ~8000–3000 cal years B.P. with coniferous‐temperate mixed forest as the dominant biome, and thereafter declined to present. The PANN reconstructions are broadly consistent with other proxy‐based paleoclimatic records from the northeastern QTP and the northern region of monsoonal China. The possible mechanisms behind the precipitation changes may be tentatively attributed to the internal feedback processes of higher latitude (e.g., North Atlantic) and lower latitude (e.g., subtropical monsoon) competing climatic regimes, which are primarily modulated by solar energy output as the external driving force. These findings may provide important insights into understanding the future Asian precipitation dynamics under the projected global warming.
