PAGES (Past Global Changes) supports research aimed at understanding the Earth’s past environment in order to make predictions for the future. We encourage international and interdisciplinary collaborations and seek to involve scientists from developing countries in the worldwide paleo-community. PAGES involves more than 5,000 scientists from over 100 countries. PAGES' scope of interest includes the physical climate system, biogeochemical cycles, ecosystem processes, biodiversity, and human dimensions, on different time scales. Founded in 1991, PAGES was a core project of the International Geosphere-Biosphere Programme (IGBP) until the end of 2015 and is now a core project of Future Earth and a scientific partner of WCRP. PAGES is funded by the U.S. and Swiss National Science Foundations. It is overseen by a Scientific Steering Committee (SSC) comprised of members chosen to represent the major techniques and disciplines, while at the same time providing regional geographic representation.
