Sessions for lectures and posters

Today, we live in a constantly warming world due to rising anthropogenic greenhouse gas emissions. The Quaternary encompasses several warmer-than-present time intervals, which offer unique insights into the climatic and environmental conditions of warmer worlds and help assessing the skillfulness of numerical climate models. In this session, we will discuss the possible drivers and mechanisms underlying the observed changes in ocean and atmospheric circulation, and their impacts on marine and terrestrial ecosystems. Warm climatic periods include short, centennial-scale fluctuations like the Roman or Medieval Warm Periods or the Holocene climatic optimum but also past interglacial like the Eemian (MIS 5e) or the Holsteinian (MIS 11). Proxy-data records from all kind of geo-archives and all parts of the world as well as approaches combining data with model simulations are welcome.

As hinted by IPCC reports, we may stand at the brink of a major and rapid climatic disruption. Climate changes occurring within a few years or decades in the Earth’s history like, for example, at the onset of Late Glacial and Holocene warming provide critical clues on the timing, dynamics and triggers of such changes. Periods of abrupt climatic shifts may be associated with increasing frequencies and amplitudes of extreme hydrometeorological events. This session invites presentations about abrupt climate changes in the Quaternary and extreme meteorological event reconstruction from various geo-archives and study areas.

Synchronising ice core, terrestrial and marine climate proxy records is the key for deciphering between regional leads and lags, and synchronous responses to past abrupt climate changes. In this respect, precise dating and high-resolution chronological constraints are of utmost importance, when exploring the spatiotemporal variability of climate change. This session focusses on the advances made in the research fields of direct dating methods (e.g., radiocarbon, U-series), annual-resolution chronologies (e.g., varves, ice layers, tree rings), and the precise integration of proxy records (e.g., through tephrochronology, cosmogenic isotopes, palaeomagnetic excursions).

Since several millennia humans transform the landscapes of central Europe and across the world. These transformations have affected sedimentation in geoarchives in various ways and, thereby, also influenced environmental and climate proxy-based reconstructions. Deforestation, for example, affects the hydrological cycle and can fundamentally change deposition processes in sedimentary basins. On the one hand, this can mask climatic signals in sediment records, but, on the other hand, cultural and societal developments in human prehistory and history can be traced in detail. To achieve this, it is crucial to distinguish between anthropogenic and climatic signals in geoarchives. In the session, we will discuss approaches and strategies to disentangle effects of human-driven land cover changes and further human activities from climate-induced changes in various geoarchives. We invite contributions on classical and novel proxies for both human activity and climate change.

Climatic and global change is implemented by the processes acting at the surface of the Earth. Processes that shape hillslopes, fluvial channels and coastlines are the agents that mobilise, transport and deposit sediments, sediments that ultimately form the geological record that is used to interpret landscape evolution and the impact of past environmental change. In this session we aim to focus on i) the consequences of environmental change on process dynamics as interpreted from sedimentary deposits and ii) implications from actualistic, process-oriented research regarding the interpretation of the geological record. We welcome contributions that resolve the initiation, nature and evolution of transients, convert proxies to process rates and vice versa, or present conceptual models that foster our understanding of the links between processes and the record they create.
