Meeting zeros in on past global change in western North America

Authors


Abstract

A major effort is under way to reconstruct past changes in climate in western North America to address uncertainties in predicting physical and biologic responses to climate change at societal timescales. Sixty scientists from an array of disciplines recently met in Albuquerque to explore the reconstruction and modeling methods that can maximize the scientific return of this effort. Paleoclimate transects are one strategy for organizing climate-related research.

Past Global Changes (PAGES), a core projectof the International Geosphere-Biosphere Program, is using several paleoclimate transects which will eventually comprise a global network of paleoclimatological sites. PEP-I—which this article discusses—is comprised of North and South America, PEP-II covers Australia and Asia, and PEP-III includes Africa and Europe.
