Past Millennia Climate Variability

Report from the workshop “Past Millennia Climate Variability: Proxy Based Reconstructions, Modeling and Methodology—Synthesis and Outlook,” held 7–10 June 2006 in Wengen, Switzerland. The workshop, funded by the Electric Power Research Institute (EPRI), PAGES, the Swiss National Centers of Competence in Research (NCCR), and CLIVAR, represented the continued efforts of the international PAGES/CLIVAR intersection to identify the key priority areas for future international collaborative research to advance understanding of the nature of natural climate variability and the extent to which human activities are causing changes.
