Past Global Changes (PAGES) is an international research network that supports studies of the Earth's past environment in order to improve understanding of future climate and ecosystem change. Established in 1991 as part of the International Geosphere-Biosphere Programme (IGBP), PAGES has since operated as a Global Research Project of Future Earth. It is based at the University of Bern, Switzerland, and is financially supported by the Swiss Academy of Sciences and the Chinese Academy of Sciences.[1][2]

Objectives

[edit]

PAGES promotes research on past climate and environmental changes, spanning the physical climate system, biogeochemical cycles, ecosystems, and human dimensions. Its aim is to provide a long-term perspective on natural variability and human impacts, thereby contributing to global change assessments such as those of the Intergovernmental Panel on Climate Change (IPCC).[3]

The network fosters international collaboration through working groups, synthesis efforts, and data sharing. It emphasizes open access to paleoclimate data, which have been widely used in IPCC reports and other global assessments.[2]

History

[edit]

PAGES was founded in 1991 as one of the IGBP’s core projects, with the goal of coordinating international paleoscience research.[1] After the closure of the IGBP in 2015, PAGES became part of Future Earth, a global sustainability science initiative.[4]

Over the decades, PAGES has organized synthesis projects and workshops that have shaped the field of paleoclimatology. Its efforts have produced widely cited datasets, such as the PAGES 2k Network reconstructions of global temperature over the past two millennia.[4][5]

Organization

[edit]

The PAGES International Project Office is hosted at the University of Bern’s Oeschger Centre for Climate Change Research. Scientific direction is provided by a Scientific Steering Committee of international experts, with additional input from an Early-Career Network established in 2017.[6]

Core Activities

[edit]

PAGES’ activities include:

  • Working groups – temporary collaborations focused on specific themes in paleoscience. These have produced synthesis papers, community datasets, and contributions to global assessments.[2][7][8]
  • Workshops and conferences – including the quadrennial Open Science Meeting and Young Scientists Meeting, which foster interdisciplinary exchange[9].
  • Publications – PAGES publishes the open-access Past Global Changes Magazine (formerly PAGES News) to disseminate paleoscience findings in an accessible format.[10]
  • Support for early-career researchers – through fellowships, training, and the Early-Career Network[11][12].

Legacy and Impact

[edit]

PAGES has played a central role in developing paleoclimate syntheses, creating community datasets, and advancing interdisciplinary collaboration in global change science.[3][2] Its research outputs have informed broader understanding of climate variability and contributed to major international assessments.
