“…During the Epi Jomon, cool conditions in northern Hokkaido (Figure 6c) and a weak summer monsoon circulation in eastern Asia (Figure 6e) prevailed. The biome reconstruction method (Prentice et al, 1992(Prentice et al, , 1996 applied to fossil pollen data from Oshima Peninsula (SW Hokkaido) also indicates cooler conditions by lowered biome scores for temperate deciduous forest during the Epi Jomon phase (Leipe et al, 2013).…”

The spatio-temporal distribution of archaeological sites in the Hokkaido region reveals hunter–gatherer population dynamics from the Upper Palaeolithic (>14,000 cal. yr BP) through the Neolithic/Jomon and Epi Jomom period ( c. 14,000–1300 cal. yr BP) to the historic Ainu period ( c. 700–100 cal. yr BP). It appears that most cultural transitions coincide with periods of climate and environmental change. However, this observation does not automatically mean causality and, therefore, other potential driving factors must be checked. The data support the hypothesis that Palaeolithic subsistence was (at least partly) based on terrestrial hunting. Paralleled by lateglacial climate amelioration, rising sea levels and a change in marine currents, this strategy shifted towards marine resources and plant exploitation at the beginning of the Jomon period. Along with continuous Holocene climate warming, Hokkaido’s Neolithic Jomon population increased culminating in the Middle Jomon period (5000–4000 cal. yr BP). Simultaneously, Jomon subsistence underwent a process of diversification and intensification in exploitation of food resources. This practice probably allowed the persistence of the Middle Jomon culture beyond the Holocene temperature optimum (around 5000 cal. yr BP). Thereafter, the population decreased until the end of the Jomon culture accompanied by a trend towards cooler climate conditions and a shift in subsistence towards a more narrow range of food resources with increased hunting and less plant food. Population re-increased during the Satsumon/Okhotsk culture periods (1500–700 cal. yr BP), which may be the result of Okhotsk immigration because of climate cooling in the regions north of Hokkaido and enhanced inner-Hokkaido trade (between Satsumon and Okhotsk) and trade with communities outside Hokkaido. During the Ainu period ( c. 700–100 cal. yr BP), site, and possibly population numbers, re-decreased significantly and concentrated in eastern Hokkaido. Whether social and/or climatic factors brought about the Satsumon–Ainu cultural transition and the observed change in population pattern remains unresolved.

“…The TWC affects the regional climate significantly (Igarashi, 2013), particularly during the cold season (November to May; see Leipe et al, 2013 for details and references therein) when the region is strongly influenced by the East Asian Winter Monsoon. Cold and dry air masses from Siberia passing over the relatively warm Sea of Japan collect its ascending moisture and heat resulting in heavy snowfalls in the western Hokkaido Region from November to April with highest amounts recorded in December (Igarashi, 2013;Leipe et al, 2013 and references therein). The Okhotsk High over the Sea of Okhotsk and the Ogasawara High in the northwestern subtropical Pacific control climatic conditions of the warm season.…”

“…The mean monthly air temperature on Rebun Island varies from À6.4°C in January to 19.4°C in August with a mean annual precipitation of 1102 mm, with highest amounts falling from September (131 mm) to December (106 mm). Nakagawa et al (2002) and Leipe et al (2013) described the predominant natural vegetation type (biome) of Rebun and Rishiri islands (as well as most of Hokkaido) as cool mixed forest. The vegetation on Rebun Island was severely impacted by human activities during the last century.…”

“…basin morphology, tsunami activities, the East Asian Monsoon system, and the global-and regional-scale sea level fluctuations that also had an influence on changes in the TWC as a main driver of the regional climate conditions. The TWC started influencing the climate in the southwestern Hokkaido region in the Middle Holocene (Leipe et al, 2013;Nishida and Ikehara, 2013). The planned high-resolution analysis of the RK12 core material will provide an opportunity to get reliable information for reconstructing the palaeolimnology of Lake Kushu in more details.…”

a b s t r a c tRebun Island is a key research area for the Baikal-Hokkaido Archaeology Project to better understand the dynamics of the Neolithic hunter-gatherers in the NW Pacific region. Hence, the ca. 19.5 m sediment core RK12 spanning the last ca. 16.6 cal. kyr BP was obtained from Lake Kushu. Our aim is to test its potential as a high-resolution multi-proxy archive. Here, we used diatoms to investigate the modern ecosystem of Lake Kushu and its surrounding area on Rebun Island and of Hime-numa Pond on Rishiri Island and selected core samples for comparison. Modern diatom and stable isotope analyses show well-mixed freshwater bodies with eutrophic, alkaline conditions. The fossil diatom and geochemical sediment analyses display three phases that represent major changes in the lake development: (i) a marshy phase (ca. 16.6-10 cal. kyr BP); (ii) a brackish water lagoon phase (ca. 10-6.6 cal. kyr BP); and (iii) a freshwater lake phase (since ca. 6.6 cal. kyr BP). This shows the major role of the post-glacial climate amelioration, global sea-level rise and marine transgression in the development of this landscape. Further analyses will provide a palaeolimnological record at (sub-)decadal resolution that will facilitate the interpretation of the hunter-gatherer dynamics.

Warmer and wetter or warmer and dryer? Observed versus simulated covariability of Holocene temperature and rainfall in Asia

Temperatures in Asia, and globally, are very likely to increase with greenhouse gas emissions, but future projections of rainfall are far more uncertain. Here we investigate the linkage between temperature and precipitation in Asia on interannual to multicentennial timescales using instrumental data, late Holocene paleoclimate proxy data and climate model simulations. We find that in the instrumental and proxy data, the relationship between temperature and precipitation is timescale-dependent. While on annual to decadal timescales, negative correlations dominate and thus cool summers tend to be rainy summers, on longer timescales precipitation and temperature are positively correlated; cool centuries tend to be dryer centuries in monsoonal Asia. In contrast, the analyzed CMIP5/PMIP3 climate model simulations show a negative correlation between precipitation and temperature on all timescales. Although many uncertainties exist in the interpretation of the proxy data, there is consistency between them and the instrumental evidence. This, and the persistence of the result across independent proxy datasets, suggests that the climate model simulations might be considerably biased, overestimating the short-term negative associations between regional rainfall and temperature and lacking long-term positive relationships between them.
