TLDR
In this article, the authors calibrate the δ 18 O record of speleothems against historical precipitation and river discharge data in central Brazil, a region directly influenced by the Southern Atlantic Convergence Zone (SACZ), a major feature of the South American Monsoon System (SAMS).About:

Global analysis reveals climatic controls on the oxygen isotope composition of cave drip water
Andy Baker,Andreas Hartmann,Wuhui Duan,Stuart Hankin,Laia Comas-Bru,Mark O. Cuthbert,Pauline C. Treble,Pauline C. Treble,Jay L. Banner,Dominique Genty,Lisa M. Baldini,Miguel Bartolomé,Ana Moreno,Carlos Pérez-Mejías,Martin Werner +14 more
TL;DR: It is found that drip waters from warmer climates have a seasonal bias toward precipitation δ18O of recharge periods, unlike in cooler climates where drip waters match well with recharge-weighted δ 18O.

TL;DR: In this paper, the authors used speleothem 87 Sr/86 Sr values as a paleo-moisture proxy in central Brazil to complement existing δ 18 O-based reconstructions of regional monsoon intensity.

Two Millennia of South Atlantic Convergence Zone Variability Reconstructed From Isotopic Proxies
Valdir F. Novello,Francisco W. Cruz,Jean-Sébastien Moquet,Mathias Vuille,M. S. de Paula,D. Nunes,Richard Lawrence Edwards,Hai Cheng,Hai Cheng,Ivo Karmann,Giselle Utida,Nicolás Misailidis Stríkis,José Leandro Pereira Silveira Campos +12 more
TL;DR: The authors used stalagmites from caves in the SACZ region of Brazil that formed during the last two millennia to reconstruct the behavior of the South American Monsoon System and consequently the rainfall distribution over Brazil during this period, which includes global climate changes that significantly affected human history, such as the Medieval Climate Anomaly and the Little Ice Age.

An extended and higher-resolution record of climate and land use from stalagmite MC01 from Macal Chasm, Belize, revealing connections between major dry events, overall climate variability, and Maya sociopolitical changes
Pete D. Akers,George A. Brook,L. Bruce Railsback,Fuyuan Liang,Gyles Iannone,James W. Webster,Philip P. Reeder,Hai Cheng,Hai Cheng,R. Lawrence Edwards +9 more
TL;DR: The stalagmite MC01 was recovered from Macal Chasm cave on the Vaca Plateau of Belize in 1995, and an initial paleoclimate interpretation was published in 2007.

TL;DR: In this article, the first high-resolution trace element record from a stalagmite in southwestern Romania covering the last 3.6 ka is presented, which provides the potential for quantitative climate reconstruction.

A High-Resolution Absolute-Dated Late Pleistocene Monsoon Record from Hulu Cave, China
Yongjin Wang,Yongjin Wang,Hai Cheng,Richard Lawrence Edwards,Zhisheng An,Jiangying Wu,Chuan-Chou Shen,Jeffrey A. Dorale +7 more
TL;DR: The record links North Atlantic climate with the meridional transport of heat and moisture from the warmest part of the ocean where the summer East Asian Monsoon originates and generally agrees with the timing of temperature changes from the Greenland Ice Sheet Project Two (GISP2).

Isotopic Patterns in Modern Global Precipitation
TL;DR: The International Atomic Energy Agency (IAEA), in cooperation with the World Meteorological Organization (WMO), has been conducting a world-wide survey of hydrogen (H/'H) and oxygen (O/O) isotope composition of monthly precipitation since 1961.
