Cristiano M. Chiessi holds a BSc (2001) in Geology from the Institute of Geosciences (IGc), University of São Paulo (USP), Brazil, a MSc (2004) in Geosciences (emphasis on Sedimentary Geology) from the IGc USP, and a PhD (2008) in Natural Sciences (emphasis on Paleoceanography and Paleoclimatology) from the University of Bremen, Germany. Between 2008 and 2009, he developed a post-doc research project in the fields of Paleoceanography and Paleoclimatology at the National Institute for Space Research (INPE). He is currently Associate Professor (2) at the School of Arts, Sciences and Humanities (EACH) from USP, leader of the Paleoclimate subgroup of the Interdisciplinary Climate Investigation Center (INCLINE) from USP, from the Paleoceanography and Paleoclimatology Laboratory (P2L) from EACH, member of the Center for Geochronology and Isotope Geochemistry Research (CPGeo) from IGc, and holds a research productivity scholarship (1C) from the National Council for Scientific and Technological Development (CNPq). He is a member of the Scientific Steering Committee of the Past Global Changes (PAGES) and of the Science Framework Working Group of the 2050 Scientific Ocean Drilling (International Ocean Discovery Program (IODP)). He was a member of the Science Evaluation Panel of IODP and of the Working Group 1 (Scientific basis of climate change) from the Brazilian Panel on Climate Change (PBMC). He is an expert in Geosciences, with special focus on Paleoceanography, Paleoclimatology and Climate Change, and the main research topics addressed by him are: abrupt climate change, meridional overturning circulation, multidecadal climate variability, South American monsoon system, carbonate and bulk sediment geochemistry, Late Quaternary, South America, and South Atlantic. During his career, he interacted with more than 400 researchers through co-authorships in scientific manuscripts. (Source: Lattes Curriculum)

Negative synergies between climate change and deforestation may force the Amazon rainforest to cross a tipping point, resulting in large-scale substitution of rainforest by non-forest ecosystems. However, this possible dieback of the Amazon rainforest remains highly uncertain at least in part due to another similarly uncertain tipping element of the climate system, namely the Atlantic mer…
Climate change affects life at all levels, from genetic structure of animal and plant populations to socio-economic organization of human communities. For Amazonia, current models project warmer and drier climates, which could make large areas unsuitable for species adapted to moist rainforest conditions and increase the susceptibility of vegetation to wildfires, thereby promoting savanni…
The Atlantic meridional overturning circulation (AMOC) plays a fundamental role in the oceanography and climate of the Atlantic realm. Atmosphere-ocean general circulation models have predicted a weakening in AMOC strength for the coming decades. Thus, a comprehensive understanding of the response of the western Atlantic Ocean to changes in AMOC on different time scales is a key issue. He…
Southeastern South America (SESA) is the most densely populated and agriculturally productive region of the continent, greatly relying on South American summer monsoon (SASM) precipitation. A comprehensive understanding of the SASM activity on different time scales is thus a key issue. Here we propose to reconstruct sea surface and thermocline temperatures in the subtropical western South…
Archives like marine sediment cores register environmental conditions through proxies in an indirect way. Thus, the appropriate reconstruction of paleoenvironmental changes rely on understanding the relationship between the aimed original environmental signal and the analyzed proxy. Here we will (i) determine how environmental signals are recorded in modern fluvial sediments, and (ii) ass…
Precipitation is arguably one of the main controlling factors of life on Earth. From foodproduction to water availability, changes in precipitation patterns can lead to social disruption and massive economic loss. Recent findings point to a possible human-driven collapse of the Atlantic Meridional Overturning Circulation. Knowing the effects of such a collapse on precipitation is crucial …
The possibility of a shutdown/marked slowdown of the Atlantic meridional overturning circulation (AMOC) by the end of this century arguable attracted much attention from the scientific community. However, large uncertainties are related to its future behavior and the associated consequences. Marine sediment cores from the Atlantic Ocean recorded the consequences of different modes of AMOC…

Oceanic gyres are important components of the climatic system which comprehend large wind-driven ocean current systems. Acting as a mechanism of meridional redistribution of energy in the oceans, they can directly impact on import climate system forcings such as atmospheric CO2 concentration. The South Atlantic Subtropical Gyre (SASG) recently became the focus of studies due to transporti…
A comprehensive calibration of proxies based on modern environmental conditions is of utmost importance for the appropriate interpretation of paleoenvironmental signals. In this project we will determine the major and minor elemental signature of modern sediments transported by the main tributaries of the Amazon River drainage basin and apply these signatures to assess past changes in pre…

Terminations (i.e., transitions from glacial to interglacial periods) and interglacial periods are key intervals to understand climate dynamics under increasing and high atmospheric CO2 concentrations, such as Earth's present and future climates. Due to its intrinsic relationship with the Atlantic Meridional Overturning Circulation and its prominent role in controlling energy distribution…
A comprehensive calibration of proxies based on modern environmental conditions is of utmost importance for the appropriate interpretation of paleoenvironmental signals. Therefore, our key goal is to characterize major and minor element compositions of modern suspended sediment transported by the main tributaries of the Amazon River drainage basin. To accomplish this goal, we will analyze…
The Quaternary climate history of the Earth is marked by global-scale changes between glacial and interglacial conditions. However, glacial terminations are not similar to each other, and ocean circulation is considered to be one of the most important driving forces of terminations by its influence on atmospheric carbon dioxide levels. Changes in the Atlantic Meridional Overturning Circul…
Concerns about human-induced climate change have promoted efforts to understand how tropical ecosystems were affected by climate oscillations in the past. To date, a significant part of the available information has been obtained by analyzing organic molecular proxies in marine sediments. An appropriate interpretation of these proxies, however, depends on the understanding of how organic …
