Breakout Sessions
In the breakout groups, participants are asked to think about our field of science in terms of future developments and societal expectations. YSM participants have been assigned to one of eight diverse discussions groups. Two breakout groups of around 10 people will address one of four topics.
> What should the research questions and priorities in paleoscience be for the next 10 years?
> Advocate for the relevance and importance of paleo-research to a funding agency or a policy maker.
> Develop better strategies to communicate paleoscience to a non-academic audience.
> What are the key educational ingredients that will ensure the success of the next generation of paleoscientists?
Parallel Sessions
 |
Climate ForcingsConvenors: Alberto Reyes, Michael Schulz This session will focus on ways to produce improved, extended, and consistent time series of climate forcing parameters, both natural and anthropogenic, including solar insolation and irradiance intensity, volcanic activity, land cover, sea ice, and greenhouse gas and aerosol concentrations. Furthermore, the session aims to quantitatively understand the causes and impacts of variations in climate forcings. Talks Diatom based sea-ice reconstruction over the past 95,000 years in the Indian Ocean sector of Southern Ocean 10:15 - 10:30 |

Regional Climate DynamicsConvenors: Ines Hessler, Olga Solomina This session seeks to achieve a better understanding of past regional climatic and environmental dynamics through comparison of reconstructions and model simulations. Presentations contribute towards a global coverage of high-resolution, well-dated paleoclimatic data, reconstructions of past climate-state parameters (e.g., temperature, precipitation, atmospheric pressure fields), a better understanding of past modes of climate variability and their teleconnections, and of rapid and extreme climate events at the regional scale. The session aims to promote data-model comparisons. Timescales covered encompass the last 130 ka, in particular the time streams of the last glacial-interglacial cycle, the Holocene, and the last 2 ka. Talks Sub-centennial Holocene fluctuations of Atlantic water inflow and sea ice distribution in the western Barents Sea, European Arctic Sahel megadrought during Heinrich Stadial 1: Evidence for a three-phase evolution of the low- and mid-level West African wind system Precession forcing of fire activity in subtropical southern Africa over the past 170,000 years Regional monsoon dynamics from small but complex paleoclimate networks Fluctuations in the Indonesian-Australian Monsoon: New insights from the Flores stalagmite record History of terrestrial precipitation in the Amazon basin (South America) during the last 240 ka |

Global Earth-System DynamicsConvenors: Thorsten Kiefer, Immaculate Ssemmanda This session looks at interactions between components of the Earth System (atmosphere, biosphere, cryosphere, hydrosphere) and the links between regional- and global-scale changes. It includes presentations that aim at synthesizing records at a global scale and address global-scale Earth System changes and their underlying processes, including their response to changes in forcings, internal feedbacks and teleconnections. Talks The past relationship between temperature and sea level from proxy records and transient ice sheet modelling |
 |
Human-Climate-Ecosystem InteractionsConvenors: Fatima Abrantes, Janet Wilmshurst This session addresses the long-term interactions among past climate conditions, ecological processes and human activities. Emphasis lies in comparing regional-scale reconstructions of environmental and climatic processes using natural archives, documentary and instrumental data, with evidence of past human activity obtained from historical, paleoecological and archaeological records. The session explores regional integration of records and dynamic modeling to: (1) understand better the nature of climate-human-ecosystem interactions; (2) quantify the roles of different natural and anthropogenic drivers in forcing environmental change; (3) examine the feedbacks between anthropogenic activity and the natural system and; (4) provide integrated datasets for model development and data-model comparisons. Talks Regional integration of lake sediment and archaeological archives: Holocene climate variability andsocio-evolutionary pathways in Cappadocia, central AnatoliaSamantha Allcock, Neil Roberts The impact of environmental change on past human societies in the Central Peloponnese (Greece)Ingmar Unkel, Helmut Brückner, Walter Dörfler, Christian Heymann, Oliver Nelle, Arndt Schimmelmann, HelenZagana |
 |
ChronologyConvenors: Alberto Reyes, Chris Turney Chronology is crucial to paleoresearch and often constrains the strength of conclusions based on paleoenvironmental reconstructions. This session supports efforts to improve tools for absolute and relative dating, and to enhance the reliability of reference timescales, as well as encourage creative new approaches to solving chronology issues. Talks U-Pb age model for an Early Pleistocene stalagmite from Corchia Cave (Italy) |
 |
Proxy Development, Calibration and ValidationConvenors: Caroline Cleroux, Denis-Didier Rousseau This session supports improvement of the precision and accuracy of paleoproxies as a basis for high-quality records and reconstructions of past global change to complement instrumental data. It includes efforts on proxy interpretation and development, analytical innovation, inter-laboratory comparisons, and calibration refinement, which lead to uncertainty reduction in proxy-based reconstructions. Talks Reconstructing Plio-Pleistocene Intermediate Water Temperatures Using Mg/Ca of Infaunal Foraminifera (Uvigerina peregrina) Holocene Climate in Western Mongolia from an Altai Ice Core Reconstructing the past millennium of hydrologic variability in the Western Tropical Pacific using the hydrogen isotopes of lipid biomarkers Climatic signal in tree-ring width chronologies of European Russia: spatial change and perspectives for paleoclimatic reconstructions |
 |
ModelingConvenors: Steven Phipps, Pascale Braconnot Numerical models provide a comprehensive, quantitative, and physically coherent framework for exploring couplings and feedbacks between the various components of the Earth System. This session supports efforts to improve model components specific for paleoresearch requirements. Talks Unraveling groundwater and surface water interaction in Central Kenya Rift lakes: Implications for Paleohydrology Integrated climate-proxy modeling using the isotope-enabled SPEEDY-IER with a focus on tropical climate |
