“…The small, shallow lakes on the TP are conisdered to have formed initially after this period, suggesting preceding arid conditions (Herzschuh, 2006;Wischnewski et al, 2011;Opitz et al, 2012;Nishimura et al, 2014), which agrees with the low lake level of Nam Co. Lake Qinghai, at the north-eastern margin of the TP (Fig. 1), persisted during this period although enhanced eolian sediment transport to the lake is evident .…”

Decadal to sub‐decadal variability of inflow, evaporation and biological productivity derived from Lake Nam Co was used to reconstruct hydrological changes for the past ca. 24 k cal a BP. The timing of these variations corresponds to known climatic shifts on the Northern Hemisphere. After a dry and cold Last Glacial Maximum the lake level of Nam Co initially rose at ca. 20 k cal a BP. Moist but further cold conditions between ca. 16.2 and 14 k cal a BP correspond to Heinrich Event 1. A warm and moist phase between ca. 14 and 13 k cal a BP is expressed as a massive enhancement in inflow and biological productivity and might be associated with a first intensification of the Indian Ocean Summer Monsoon coinciding with the Bølling–Allerød complex. A two‐step decrease in inflow and a contemporaneous decline in biological productivity until ca. 11.8 k cal a BP points to cool and dry conditions during the Younger Dryas. Lake levels peak at ca. 9.4 k cal a BP, although hydrological conditions remain relatively stable during the Holocene with only low‐amplitude variations observed.

“…Lake Karakul, located on the westernmost QTP, experienced high lake levels from ∼16 to ∼12 ka (Komatsu and Tsukamoto, ). Lacustrine records in Pumoyum Co show that deglaciation in the southern QTP started at ∼18.5 ka, and moisture increased after ∼16.5 ka, with the summer monsoon intensifying after ∼15 ka (Nishimura et al , ).…”

Last deglacial and Holocene lake level variations of Qinghai Lake, north-eastern Qinghai-Tibetan Plateau

et al. 2015

Qinghai Lake is of significance for paleoclimate research because it lies in a pivotal region that is influenced by both the mid‐latitude Westerlies and the low‐latitude Asian summer monsoon (ASM). Most published lake level histories of Qinghai Lake are interpreted from drill‐core proxies. Here we combine geomorphic shoreline investigations with optically stimulated luminescence dating to constrain lake level variations since the last deglacial. The results indicate that two periods of highstands occurred during the last deglacial (∼16–14.9 and ∼12.6–12.2 ka), and that lake levels were 6–7.4 m higher than at present. Lake levels dropped abruptly during the Younger Dryas, and were generally low with frequent fluctuations during the early Holocene. Qinghai Lake reached its highest Holocene level, 9.1 m higher than modern, at ∼5 ka, and has regressed during the past 2 ka. We propose that high lake levels during the last deglacial were due mainly to melting glacial and permafrost waters, supplemented by enhanced Westerlies precipitation and decreased evaporation during Heinrich Event 1 (∼16–14.9 ka) and increased ASM rainfall during the Bølling–Alleröd warm period (∼14–12 ka). Lake level fluctuations during the Holocene were generally in accordance with moisture variations in the marginal monsoon zones of inland China.

“…A major massive migration took place from the southern tropical belt of eastern Asia rather than from the putative scattered northern refugia, suggested by the phylogeographic studies. in the western high Tibetan plateau, within the subtropical zone, despite a different vegetation type during the LGM (sclerophyllous mixed oak and conifer forests), there is also simultaneously a profound biome change over the altitudinal belts (Wang et al 2018;Nishimura et al 2014;Cheng et al 2018).

News 6th Open Science Meeting and 4th Young Scientists Meeting pAGES is proud to announce the next meetings will be held in Agadir, Morocco, from 16-22 May 2021. The winning bid was submitted by a consortium from Université ibn Zohr, Sultan Moulay Slimane University and Mohamed Vi polytechnic University. They are now being assisted by Universiapolis for the events' organization. Held once every four years, the OSM and YSM are the premier events in pAGES' calendar and provide an invaluable opportunity to bring the international past global change community together to share, discuss, learn, and plan for the future. Abstract submission and registration opens 1 July 2020. We look forward to seeing you there! All details: pages-osm.org Rescheduling of workshops/meetings The COViD-19 pandemic has resulted in several pAGES workshops and supported meetings being cancelled or postponed-groups affected include ACME, C-pEAT, CVAS, LandCover6k, pEOpLE 3000 and potentially more. please check pAGES calendar for updated news and information regarding rescheduling: pastglobalchanges.org/calendar/upcoming Working group news Two working groups have started their second phases: Climate Variability Across Scales (CVAS; pastglobalchanges.org/cvas) Speleothem isotopes Synthesis and AnaLysis (SiSAL; pastglobalchanges.org/sisal) Three groups recently sunsetted: paleoclimate reanalyses, Data Assimilation and proxy System modeling (DApS) Ocean Circulation and Carbon Cycling (OC3) Global paleofire Working Group 2 (GpWG2) Find out more about them here: pastglobalchanges.org/science/wg/former Did you know pAGES working groups have designated mailing lists?
