Theme
Objective:
Understanding of paleoclimate variability and dynamics can provide a key to future projection in the anthropogenic era. In past decades, both geological proxies and model results have provided valuable insights into past climate variability and dynamics at tectonic to seasonal time scales. However, intensive data‐model comparisons remain sparse due to limited brainstorm between paleoclimatologists and modelers. It is therefore timely to synthesize mulitscale climate variability and dynamics across different spatial‐temporal scales. The symposium invites contributions of terrestrial and marine proxy data, sensitivity and transient modeling results, and data‐model integration.
Two sessions:
Session 1: Suborbital to millennial climate changes during the Quaternary. This session aims to address the characteristics of rapid climate changes recorded in terrestrial, marine and ice‐core archives, and to assess their dynamical links to external and internal forcings.
Conveners: Jerry McManus & Youbin Sun
Session 2: Centennial to seasonal climate variability over the past thousands of years. This session will focus on centennial to seasonal climate variability over past thousands of years based on annually resolved archives such as ice core, speleothem, tree ring, coral and marine bivalve shells. Main objective is to decipher the seasonality and extreme climate/weather events from natural archives.

Outline of Institute
The Institute of Earth and Environment, Chinese Academy of Sciences (IEECAS),
as an outgrowth of the Xi'an Laboratory of Loess and Quaternary Geology of the
Chinese Academy of Sciences, was initially founded in 1985. IEECAS was ordained by
the Chinese Academy of Sciences in 1999.
With particular interests in loess, Quaternary geology, and global change studies,
research areas of IEECAS include, but are not limited to the history, process and
dynamics of environmental changes, Quaternary chronology, numerical modeling of
past climate, and the integrated studies of Earth environment system at various time
scales.
Sticking in the forefront of Quaternary and global changes studies, IEECAS
continues its effort to improve the theoretical framework of the dynamics of the
coupled Asia monsoon‐aridity environment through multidisciplinary studies of
various geologic‐biological records. We aim to establish an internationally renowned
research center characterized by continental environment studies.
12
Facility Construction of IEECAS
We aim at establishing an open sharing scientific and technological platform
based on the notion of “Improving conventional methods, and devolping
sophisticated methods”. Our laboratory complex includes the Quaternary chronology
systems, physiccal and chemical tracing systems, and numerical simulation and
integration system.
