“…yr BP until modern warming. This broadly agrees with the results of Ge et al (2003Ge et al ( , 2010 and Chen et al (2005), and with recent modelling based on pollen records (Li et al, 2018), although exact matches are not to be expected. The warm and cold phases of the last millennium have been confirmed from historical records (Ge et al, 2003;Zhang et al, 2008b), and speleothem analysis (Chu et al, 2012) links these historical changes to monsoon variability (Zhang et al, 2008a).…”

“…yr BP, have been found in the Taihu lowlands at several locations (Chen and Stanley, 1998). The coring site is adjacent to the current Lake Dianshan which, as shown for Taihu lake by sedimentary and historical records (Hong, 1991;Shi and Zhu, 2004), would have been considerably larger after about 2500 cal yr BP, with episodes of higher rainfall (Gu et al, 2018;Li et al 2018; Fig. 7F).…”

“…This was very clear during the transition from the Middle Holocene to the Upper Holocene (Innes et al, 2014), with the change to a still humid, but colder and wetter climate (Yao et al, 2017), which also had very serious impacts on Neolithic cultures in the region, causing the replacement of thermophilous subtropical trees by cold-tolerant deciduous and coniferous trees. There have also been significant climatic fluctuations in the last few millennia, however, of both temperature (Yang et al, 2002;Ge et al, 2003Ge et al, , 2013Li et al, 2018) and rainfall (Zheng et al, 2006;Li et al, 2018;Lu et al, 2015Lu et al, , 2018 including extreme events. Temperature fluctuations were probably due to changes in solar activity (Park, 2017), within a general cooling trend (Winkler and Wang, 1993;Jian et al, 1996;Ge et al, 2003).…”

“…During this period, the SCS was connected to outer oceans only by the Bashi Channel (Shyu et al, 2001). Throughout the time of deglaciation, the southern SCS experienced regional climatic changes due to geo-dynamic events, such as the submergence of Sundaland and the opening of the Indonesian throughflow (Sun and Li, 1999;Li et al, 2018). Due to the changes that occurred in the landmass and the heat budget, wind and monsoonal patterns changed, affecting the terrestrial paleo-productivity history by altering vegetation cover and vegetation type (such as trees, shrubs, herbs, and grasses) (Broecker et al, 1988;Miao et al, 1994;Wang et al, 1999;Shyu et al, 2001;Huang and Tian, 2012).…”

Sediment Provenance of the Nansha Trough Since 40 ka B.P. in the South China Sea: Evidence From δ13Corg, TOC and Pollen Composition

Geochemical proxies in organic matter (OM) are considered to be reliable proxies for deciphering types of paleo-vegetation (C3 plants and C4 plants) and their abundance. The contributions of total organic carbon (TOC), stable carbon isotopes (δ 13 C org), total nitrogen (TN) and organic carbon to total nitrogen ratios (C/N) were obtained from a gravity core NS07-25 (6 • 39.945 ′ N, 113 • 32.936 ′ E, water depth 2006 m), extracted from the southern South China Sea (SCS). These data were used to reconstruct the climate changes of the Nansha Trough since 40 ka B.P. by comparing them with pollen data from the same core, and this comparison provides better sediment provenance details in the study area. During the periods between 37 and 27 ka, and from 12.5 ka to modern day, the majority of terrestrial sediment received from Borneo, and some climatic events have been governed by aeolian fluxes from mid-latitude areas (mainland China). These periods were relatively humid, compared to 27-12.5 ka, where the majority of terrestrial sediment came from the Sunda Shelf through riverine pathways. This study serves as the first study to correlate deep oceanic pollen and geochemical proxies in order to identify the weaken terrestrial OM signals in the deep ocean.

Dipolar mode of precipitation changes between north China and the Yangtze River Valley existed over the entire Holocene: Evidence from the sediment record of Nanyi Lake

Instrumental data indicate the occurrence of a dipolar pattern of precipitation anomalies between north China and the Yangtze River Valley (YRV), which was termed “northern drought (flood)—southern flood (drought)” scenario. It has been shown that this pattern occurred during the Medieval Climate Anomaly (MCA) and the Little Ice Age (LIA). However, there are questions about whether this dipolar pattern also occurred during the entire Holocene, and the mechanism responsible. Addressing these questions is of fundamental importance for understanding the spatiotemporal evolution of precipitation in East Asian summer monsoon region. Numerous studies of north China have demonstrated that the mid‐Holocene was humid, and the early and late Holocene were dry. However, there are relatively few equivalent studies in the YRV. To this end, we conducted detailed geochemical analysis of an AMS 14C‐dated sediment core from Lake Nanyi in the YRV. Our results indicate humid periods at Lake Nanyi occurred during 11.5–8.0 ka and from 2.0 ka to the present, while dry conditions occurred during ~8.0–2.0 ka. These results, together with published records from Dajiuhu peatland and Heshang Cave, collectively indicate in the YRV, the mid‐Holocene (~8.0–3.0 ka) was dry, while the early and late Holocene were humid, which is the inverse of the pattern in north China. Thus, we conclude there was an asynchronous evolution of hydroclimatic changes between north China and the YRV during the Holocene. We interpret this dipolar pattern as the result of ENSO variations: in a La Niña‐like state, the Western Pacific Subtropical High retreated northeastward, which would enable the rainfall belt to move northward and result in increased (decreased) precipitation in north China (the YRV). Sea surface temperature records from the Pacific Ocean and model simulations support this mechanism: a La Niña‐like state in the mid‐Holocene resulted in more (less) precipitation in north China (the YRV).
