PP33A:
Arctic Climate Change: Paleoclimate and Paleohydrologic Perspectives II Posters


Session ID#: 9110

Session Description:
Future climate change in the Arctic is expected to involve increased surface temperatures as well as changes in the amount and seasonality of precipitation. Since the Arctic contains large quantities of stored carbon, understanding the response to past changes will help us predict the future and whether permafrost regions become a carbon source or sink. Many proxy records from the Arctic have been used to infer past temperature, while fewer have been used to reconstruct hydroclimate, despite the fact that hydroclimatological changes are an extremely important aspect of arctic climate variability. This session will bring together researchers working to reconstruct Arctic paleoclimate on a variety of timescales. We are particularly interested in research that addresses hydroclimate changes but welcome contributions from researchers generating a variety of paleoclimate data from studies on land or in the coastal ocean, synthesizing and calibrating existing datasets, and working to model impacts of climate changes.
