PAGES - Past Global Changes

Welcome to PAGES

The PAGES (Past Global Changes) project is an international effort to coordinate and promote past global change research. The primary objective is to improve our understanding of past changes in the Earth system in order to improve projections of future climate and environment, and inform strategies for sustainability. ... more

PAGES is open and inclusive to all scientists interested in past global changes. In February 2017, PAGES' parent organization Future Earth published a statement affirming its commitment to supporting international collaboration and the free movement of scientists and flow of data, information and knowledge for global sustainability. PAGES fully supports the Future Earth statement.

PAGES is funded by the US National Science Foundation and the Swiss Academy of Sciences, and supported in-kind by the University of Bern, Switzerland. It is a Global Research Project of Future Earth and a scientific partner of WCRP.

DCV paper in BAMS

Details: Published: Thursday, 26 April 2018 14:58

A succinct review paper about Decadal Climate Variability (DCV) and predictability was recently published in the Bulletin of the American Meteorological Society (BAMS).

Written by Christophe Cassou et al., it is a result from the PAGES-supported "CLIVAR-ICTP Workshop on Decadal Climate Variability and Predictability: Challenge and Opportunity" meeting held in Trieste, Italy, in November 2015.

The study of DCV and predictability is the interdisciplinary endeavor to characterize, understand, attribute, simulate, and predict the slow, multi-year variations of climate at global and regional scales.

GPWG2 fire impacts in Eos

Details: Published: Wednesday, 25 April 2018 10:51

PAGES' Global Paleofire Working Group 2 (GPWG2) held a workshop in October 2017 to foster collaboration among different research communities interested in fire impacts and vegetation dynamics.

Find out what was discussed in their report, titled "Paleofire Knowledge for Current and Future Ecosystem Management", published yesterday in Eos.

Lake-core data collected during the workshop will be added to the group's Global Charcoal Database.

New paper in 2k special issue

Details: Published: Wednesday, 11 April 2018 11:01

Hans Linderholm et al. summarise the current understanding of Arctic hydroclimate during the past 2000 years in a new contribution to the PAGES 2k Network special issue of Climate of the Past.

Published yesterday, the paper, titled "Arctic hydroclimate variability during the last 2000 years: current understanding and research challenges", reviews the main natural archives and proxies used to infer past hydroclimate variations in this remote region and outlines the difficulty of disentangling the moisture from the temperature signal in these records.

It also shows the potential for providing a high-resolution hydroclimate reconstruction for the Arctic and a comparison with last-millennium simulations from fully coupled climate models. Read the paper here.

CoralHydro2k workshop report

Details: Published: Tuesday, 10 April 2018 11:42

Find out what happened at the PAGES 2k Network CoralHydro2k project meeting in September 2017 in their recent Eos report.

Jens Zinke et al. discuss why corals are a key archive for understanding variability over seasons, years and decades in "Reconstructing climate and environment from coral archives".

The project's future plans are also highlighted.

Antarctica 2k - EGU and BBC

Details: Published: Monday, 09 April 2018 14:11

A paper from the PAGES 2k Network Antarctica 2k project, discussed at the European Geosciences Union (EGU) General Assembly in Vienna, Austria, today, has been featured on the BBC News website.

Presented at the EGU by 2k Network member Liz Thomas, authors use 79 ice-core snow accumulation records in their paper "Regional Antarctic snow accumulation over the past 1000 years", published in Climate of the Past in November 2017.

Thomas said the work was undertaken to try to put current ice losses into a broader context. Read the BBC interview with Thomas here.
