Title Spatial and temporal complexity in Quaternary desert datasets: implications for interpreting past dryland dynamics and understanding potential future changes
CommissionTERPRO
Description

In recent years, a large amount of new data on the nature, timing, and extent of past climatic and hydrologic conditions in drylands has become available. As a result, the spatial and temporal complexity of the patterns of change is becoming increasingly evident, requiring revised interpretations of existing and new data sets; as well as regional correlations.
This symposium will address the significance of the emerging patterns of spatial and temporal complexity and rates of change in past arid systems for interpreting past dryland dynamics and understanding potential future changes. Papers reporting new research, revised interpretations, and discussions of complexities, controversies and routes to their resolution are invited from all global dryland contexts.
