PP41E:
Climate of the Common Era I

Submit an Abstract to this Session



Session ID#: 33748

Session Description:
This session highlights recent work on all aspects of the climate of the last 2000 years (the Common Era), using new proxy records, data syntheses, reconstruction methodologies, proxy system modeling, and paleoclimate model simulations. Contributions that combine several of the above areas or that focus on developing improved quantitative estimates of uncertainty are particularly welcome. A focus of this year's session will be on improving our understanding of past climate extremes and their associated atmosphere-ocean dynamics during the Common Era. New means of observing and reconstructing extreme events, as well as model-data comparisons over the Common Era that seek to understand their frequency and magnitude in response to internal variability and radiative forcing are encouraged.
