Palaeoclimatic changes in the Qinghai Lake area during the last 18,000 years
TLDR
In this article, multi-proxy analysis of a sediment core from Qinghai Lake, including pollen, carbonate, TOC, TN and δ 13 C of organic matter, was used to document regional climatic changes during the last 18,000 years.About:

Holocene moisture evolution in arid central Asia and its out-of-phase relationship with Asian monsoon history
Fahu Chen,Zicheng Yu,Zicheng Yu,Meilin Yang,Emi Ito,Sumin Wang,David B. Madsen,Xiaozhong Huang,Yan Zhao,Tomonori Sato,H. John B. Birks,H. John B. Birks,Ian Boomer,Jianhui Chen,Chengbang An,Bernd Wünnemann +15 more
TL;DR: In this article, the authors synthesize palaeoclimate records from the mid-latitude arid Asian region dominated today by the Westerlies ("arid central Asia" (ACA)) to evaluate spatial and temporal patterns of moisture changes during the Holocene.

Timothy Jull,Yanjun Cai,Yongsong Huang,Xuefeng Lu,Hong Chang,Yougui Song,Youbin Sun,Hai Xu,Weiguo Liu,Zhangdong Jin,Xiaodong Liu,Peng Cheng,Yu Liu,Li Ai,Xiangzhong Li,Xiuju Liu,Libin Yan,Zhengguo Shi,Xulong Wang,Feng Wu,Xiaoke Qiang,Jibao Dong,Fengyan Lu,Xinwen Xu +29 more
TL;DR: The longest and highest-resolution drill core from Lake Qinghai on the northeastern Tibetan Plateau is presented, which uniquely records the variability of both the Westerlies and the ASM since 32 ka, reflecting the interplay of these two systems.

TL;DR: A well-dated, pollen-based, ~20-yr-resolution quantitative precipitation reconstruction from an alpine lake in North China, which provides for the first time a direct record of EASM evolution since 14.7 ka, points to strong internal feedback processes driving the EASm, and may aid the understanding of future monsoon behaviour under ongoing anthropogenic climate change.

Asian monsoon oscillations in the northeastern Qinghai–Tibet Plateau since the late glacial as interpreted from visible reflectance of Qinghai Lake sediments
TL;DR: This article used reflectance spectroscopy to characterize the sediments in a 795-cm long core taken from the southeastern part of the lake and found that redness increases at times of increased precipitation, that is, as monsoon strength increases.

A Pervasive Millennial-Scale Cycle in North Atlantic Holocene and Glacial Climates
Gerard C. Bond,William J. Showers,Maziet Cheseby,Rusty Lotti,Peter Almasi,Peter B deMenocal,Paul Priore,Heidi Cullen,Irka Hajdas,Georges Bonani +9 more
TL;DR: In this paper, the North Atlantic deep sea cores reveal that abrupt shifts punctuated what is conventionally thought to have been a relatively stable Holocene climate, and they make up a series of climate shifts with a cyclicity close to 1470 ± 500 years, which is the most recent manifestation of a pervasive millennial-scale climate cycle operating independently of the glacial-interglacial climate state.

Comparison of oxygen isotope records from the GISP2 and GRIP Greenland ice cores
Pieter Meiert Grootes,Minze Stuiver,James W. C. White,Sigfus J Johnsen,Sigfus J Johnsen,Jean Jouzel +5 more
TL;DR: In this article, the authors present the complete oxygen isotope record for the Greenland Ice Sheet Project 2 (GISP2) core, drilled 28 km west of the GRIP core, and observe large, rapid climate fluctuations throughout the last glacial period.

Holocene climatic instability: A prominent, widespread event 8200 yr ago
Richard B. Alley,Paul Andrew Mayewski,Todd Sowers,Minze Stuiver,Kendrick C. Taylor,Peter U. Clark +5 more
TL;DR: The most prominent Holocene climatic event in Greenland ice-core proxies, with approximately half the amplitude of the Younger Dryas, occurred ∼8000 to 8400 yr ago.

TL;DR: In this article, the authors present evidence that the most recent six Heinrich layers, deposited between 14,000 and 70,000 years ago, record marked decreases in sea surface temperature and salinity, decreases in the flux of planktonic foraminifera to the sediments, and short-lived, massive discharges of icebergs originating in eastern Canada.

Applications of organic geochemistry to paleolimnological reconstructions: a summary of examples from the Laurentian Great Lakes
TL;DR: The organic matter content of lake sediments contains information that helps to reconstruct past environmental conditions, evaluate histories of climate change, and assess impacts of humans on local ecosystems as discussed by the authors, and serve as proxies of organic matter delivery and accumulation.
