PP43F:
Climate of the Common Era I


Session ID#: 10843

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.  This year the session will emphasize estimates of hydroclimate variability and associated dynamics over the Common Era.  New means of observing and reconstructing hydroclimate as well as model-data comparisons that focus on regional or global hydroclimatic variability at timescales from seasons to centuries are particularly encouraged.
