Dear Colleagues,

We would like to draw your attention to an AGU session: PP002. A high-temporal-resolution view of deep-time “greenhouse climates”

Confirmed Invited Speaker
Emily J. Judd, University of Arizona/Smithsonian
Christine Shields, National Center for Atmospheric Research

Session Abstract
When paleoclimatologists study the distant warm periods, we do so to better understand our future. A common dilemma, however, is that the temporal resolution of available records is typically >thousands of years, much longer than the human life span and therefore less informative for the short-term carbon and climate feedbacks, near-term climate projection, mitigations and policy making. Studies of “deep-time” yet with a high-temporal-resolution view are much needed.

We solicit contributions from both the data and model perspectives with the goal of resolving climate variability on seasonal-, decadal- to centennial-timescales in past greenhouse climates. Certain sedimentary and fossil archives (e.g., varved deposits and accretionary carbonate skeletons) have the resolution and continuity to provide the necessary data. Novel applications of geochemistry (e.g., δ18O of single forams) also provide useful insights. Model simulations of relevant climate dynamical and carbon cycling processes from a greenhouse world are also welcomed.

Both in-person and virtual participation are welcome. Submission deadline is 4 August 2021.

Have a good weekend and best regards,

Yige Zhang, Linda C Ivany and Jiang Zhu
