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
