Topic: CO2 reconstructions across the MPT


As part of the EU Beyond-EPICA Ice Core (BE OI) project, and as co-chairs of the BE OI Climate and Carbon Cycle feedback Consortium, we are organizing a short online seminar series during the autumn 2023.

This seminar series is aiming at providing an update on advances related to paleoclimate reconstructions and simulations across the MPT and to our understanding of this major climatic transition based on proxy records from natural archives and climate modelling efforts.

Given the great interest in these topics for the paleoclimate research community, we are opening this seminar series to the public and invite you to join. 


The format of the seminar series is as follows: a seminar will take place once a month between September and December 2023 from 2-3pm CET. 

For each seminar, two speakers working on related topics will present their recent studies, and each speaker will give a 20 min talk followed by a 10 min discussion.
