The consequences and impact of climate change for ecosystems, landscapes and human societies depend on the rate, duration and nature of change. While paleoclimate archives provide ample records of such climatic variability, a lack of proxy sensitivity, in combination with chronological uncertainties in age models, often make it difficult to identify the actual agents of change for a specific region. A key example is the Younger Dryas (YD), which is expressed in Western Europe as a significant cold period, but also drying, which possibly lagged the cooling by a century or so. Contrary, in Eastern Europe, paleodata suggest that cooling was restricted to winter season, only, whereas summer temperatures were mostly stable. The resulting massive ecosystem change during the YD has been attributed variably to cooling as well as drying and/or possible changes in seasonality.
With significant advances in relative and absolute chronological techniques (e.g., tephrochronology and cosmogenic radionuclide synchronization) which enable the comparison of ecosystem responses on common timescales, as well as an increased proxy understanding and modelling, it is now becoming possible to disentangle the different components of the climate system and compare their responses over continental scales.
Focussing on the last glacial-interglacial cycle we invite contributions that assess, diagnose, model and quantify the agents of climatic change, as well as those that permit new insights into the rates during abrupt transitions. We particularly welcome research (including modelling studies) that address the importance of temperature, hydrological and seasonal changes using archives (e.g., ice core, marine and terrestrial), and those that advance our understanding of the responses of different paleoclimate proxies. A better understanding of both the cause AND effect of past abrupt climate changes and spatio-temporal differences is needed for a better prediction of the consequences of the anthropogenic interference with the climate system.

How to access CL1.6
Session CL1.6 runs as a vPICO session. Everybody, conveners/chair/speakers as well as attendees, join the live session page on EGU21. While attendees stay on this live session page and see the live presentations via stream, you as convener/chair/speaker are required to enter the BigBlueButton (BBB) live video chat to give your presentation.
Please keep the live session page open on this browser tab and join the BBB video chat in parallel on another browser tab through the button below. Your personal breakout text chat following the live presentations are linked from the live session page tab, not from the additional BBB video chat tab.Enter BBB video chat
