This proposal seeks funding for reconstructing climate variability and change during the past millennium (850 C.E -1850 C.E) using speleothem and tree-ring records from the South American monsoon region. The last millennium is a key period for climate reconstruction, because it allows analyzing natural climate variability in the absence of human influence. It is also a time period that includes significant climate anomalies (the Little Ice Age and the Medieval Climate Anomaly), which left a significant imprint on tropical and subtropical South America. There is still a lack of spatial detail to explain the waxing and waning of the monsoon over the past millennium, yet understanding its sensitivity to external forcing is of fundamental importance, given the current rapid increase in greenhouse gas concentrations. This PIRE call is an opportunity to establish a much closer collaboration, with colleagues in the US and in Argentina, fostered by multiple fellowships for student and postdoc exchange. The research expertise of the Brazilian, Argentinian and US labs is highly complementary and a joint PIRE project would enable us to mesh the expertise in speleothem research and isotopic lab analyses from USP with the climatic and isotope modeling expertise available at UAlbany and the tree rings specialization at lANIGLA (Mendoza) and Columbia University (USA). This collaboration will allow us, for the first time, to merge speleothem and tree ring records, thereby taking advantage of their respective strengths to produce a much more comprehensive and coherent climate reconstruction over tropical South America, than is currently available.
