Session 5 "Climate – Present, Past and Future" may interest the PAGES community.
5.1 The imprint of astronomical climate forcing: geochronometer and paleoclimate archive
Christian Zeeden, Stefanie Kaboth-Bahr, Anna-Joy Drury, Qiang Fang, Mehrdad Sardar Abadi
Keynote: Dr. Daniel Veres
The pacing of the global climate system by variations in orbital parameters is clearly demonstrated in the timing and specific patterns of various geoarchives, including sapropels, glacial/interglacial cycles and many other examples. The imprint of astronomical cycles can be used as high-precision geochronometer, and as paleoclimatic information. Extreme events can especially be expected to relate to extremes in insolation.
We invite contributions utilizing the imprint of Milankovic cycles as preserved in the geological record in any way, including the often poorly understood mechanisms that translate this forcing into geoarchives. Submissions exploring orbital time scales, proxy data and/or modelling work are welcome; we aim to bring together studies focused on global and regional climate responses to astronomical forcing at different time scales.
5.2 Geological archives and proxies of polar environmental change: Data basis for constraining numerical simulations
Johann Philipp Klages, Juliane Müller, Gerhard Kuhn
Keynote: Dr. Peter Köhler, Alfred-Wegener-Institute, Bremerhaven, Germany
In recent years, geoscientific data provided considerable insights into the environmental past of polar regions. Conventional coring, seafloor drilling, and terrestrial campaigns led to increasing data availability of past environmental and ice-sheet change at both poles. As these are the regions most sensitively reacting to climatic changes, reliable datasets of past variations are critical for constraining numerical models aiming at simulating future changes more robustly.
We therefore invite contributions from colleagues working in marine and terrestrial settings in both polar regions on various timescales. We particularly ask for contributions that integrate field data with numerical modeling, i.e. utilize past variations as target values for calibrating numerical simulations in order to improve their predictive capabilities for future scenarios.
5.3 Advances in terrestrial and marine carbonate archives – novel proxies and innovative techniques to decipher past climate variability
Dana Felicitas Christine Riechelmann, Maximilian Hansen, Sophie Warken, Michael Weber
Keynote: Dr. Franziska Lechleitner, University of Bern, Switzerland
The use of carbonate-based paleoclimate archives has gained increasing importance to obtain reliable and detailed information on past climate and environmental variability in order to better understand the modern climate regime and the influence of anthropogenically induced global warming. In the last decades, the diversity of geochemical proxies available in carbonate palaeoclimate archives have emerged rapidly and significantly. Trace elements and traditional stable isotopes of oxygen and carbon have been supplemented with numerous non-traditional stable isotope systems such as B, Li, Ba, Mg, Ca, Sr, U, N, Δ17O, Δ47.
In addition, the study of organic matter in carbonaceous archives and investigation of different biomarkers has massively expanded over the last years. Most importantly, recent developments in analytical techniques allow for improved precision, unprecedented resolution or smallest sample amounts. Furthermore, sophisticated isotope enabled diffusion-reaction models as well as high resolution experimental approaches significantly improved our understanding of the underlying fractionation processes. All these novel geochemical proxies and innovative methods open new advances towards qualitative and quantitative reconstruction in terrestrial and marine palaeoclimate studies and allow for multi-proxy approaches at different spatial and temporal scales.
This session aims to bring together researchers from different fields of palaeoclimate research to share their knowledge, and allow inter-disciplinary exchange in order to apply these proxies to other palaeoclimate archives. We especially invite early career researcher to submit their abstracts to this interdisciplinary session. This will inspire both young researcher as well as senior scientists to apply new multi-proxy research approaches to study past climate variability.
