Past Global Changes (PAGES) is a registered paleoscience association that focuses on scientific research and networking related to past global changes. They aim to understand measurable changes in climate and biosphere on a global scale or with a global impact. PAGES is a Global Research Network of Future Earth and has formed scientific partnerships with organizations like the World Climate Research Programme (WCRP) and the Inter-American Institute for Global Change Research (IAI).

PAGES supports research on the Earth's past environment to improve predictions of future climate and inform strategies for sustainability. They provide small grants for workshops, connect scientists through their databases, offer website support, and facilitate outreach and press releases for publications by their working groups. PAGES encourages international and interdisciplinary collaborations and promotes the involvement of scientists from developing countries.

Their science is conducted through working groups that address broad questions and produce synthesis products. Anyone can get involved by signing up for mailing lists, attending workshops and meetings, and proposing new working groups. PAGES is located at the University of Bern in Switzerland and communicates through their website, monthly e-news, social media platforms, and scientific journals.

They receive financial support from organizations like the Swiss Academy of Sciences, the Chinese Academy of Sciences, and the University of Bern. PAGES also dedicates activities to early-career scientists through their Early-Career Network (PAGES ECN), as well as the Young Scientists Meeting (YSM) which helps early-career researchers enhance their skills and expand their network.
