Sedimentary records of Holocene climate and environmental change

Session ID#: 157060

Session Description:
Environmental changes over the Holocene (last ~11,650 years) are important to study because climate over this interval has been modulated both by long-term climate variability and by anthropogenic activities, both of which influence 21st century global warming and its impacts. Through using varied sedimentological, biological, and geochemical (inorganic and organic) proxies, sedimentary records have been crucial in resolving environmental changes on Holocene timescales, including carbon cycling, ecology, extreme events, hydroclimate, and more. Such records are sourced from depositional environments such as lakes, oceans, soils, coastal zones, peatlands, and wetlands distributed globally. In this session, we seek contributions from researchers of all career stages and demographics to highlight research on proxy-based reconstructions from diverse Holocene sedimentary records (terrestrial and marine). We enthusiastically welcome studies that are multi-disciplinary, connect modern and paleo datasets, combine proxy data with model simulations, or demonstrate how a paleo perspective can inform future adaptation or mitigation strategies.
