Sessions > Symposium E: Paleoclimate

Session E1: Reconstructing paleoclimates - from data to models

This session aims to explore climate reconstructions and processes throughout the Devonian to Permian times. In recent years, the number of available data has grown exponentially, including paleontological, sedimentological, isotopic, and geochemical data. Several questions arise, as (i) is there a unified picture emerging from this large amount of data, or (ii) how do we separate the global evolution and long-term trends from regional conditions and more pronounced changes or (iii) are results from numerical models and geological observations a good fit? The session is open to all studies and approaches shedding light on the upper Paleozoic climate.

Session E2: Global carbon cycling, paleoclimate changes and marine redox landscape during the Late Paleozoic Ice Age

The Late Paleozoic Ice Age (LPIA, 360–260 million years ago) is the thus far longest-lived icehouse climate in the Phanerozoic and the only one that recorded a transition from an icehouse to a greenhouse climate since the appearance of advanced plants and a complex terrestrial ecosystem. The LPIA is often compared to the Cenozoic icehouse, which may provide a unique deep-time geological analogue to modern global warming. The LPIA is featured by dynamic global carbon cycling and paleoclimate changes, which are only moderately studied. Although the atmospheric paleo-O₂ during the LPIA is hypothesized to be the highest during the entire Earth history, the marine redox landscape remains poorly constrained. This session aims to provide a platform for colleagues to introduce their recent research progress and to exchange their knowledge on the LPIA, including, but not limited to, the following subjects: (1) global and regional carbon cycling, (2) continental weathering, (3) marine primary productivity and redox conditions, and (4) biogeochemical and Earth system modeling of the LPIA. All these subjects from astronomical (“Milanković”) timescale to tectonic timescale are all welcome.
