The PAGES Open Science Meeting (OSM) is an international and multi-disciplinary platform/ meeting designed to encourage interaction between scientists of all career stages, disciplines and regions. The hope is that many contacts are made, and many collaborations and joint activities begun, that will endure long after the meetings themselves.

Held every four years in a different location, both the OSM and Young Scientists Meeting (YSM) provide an invaluable opportunity to bring the past global change community together from around the world to share, discuss, learn, and plan for the future.

The theme of next year's OSM is "Earth System Changes from the Past towards the Future".

There are 31 sessions, covering a wide range of topics:

1. 01. Hydroclimate of the Common Era (The 2k Network)
2.  02. Scales and Scaling in the Climate System: climate, macroclimate, megaclimate
3.  03. Human Traces of Earth System Changes
4.  04. Transdisciplinary approach to address environmental issues
5.  05. Understanding drivers of paleo sea-level changes through proxies and modeling
6.  06. Reconstructing Marine Responses: Oxygen and pH Dynamics Through Time
7.  07. The end of the ‘41-kyr world’ and the transition to the ‘100-kyr world’
8.  08. Leveraging paleoecology for sustainable ecosystem restoration in the Anthropocene
9.  09. Pleistocene to Common Era climate reconstructions and insights from speleothem and allied archives
10.  10. Double Volcanic Eruptions - Identification, Attribution and Impacts
11.  11. New horizons for paleosciences outreach
12. 12. Arctic to sub-Arctic climate evolution during the Quaternary and their impact on modulating paleoclimate and paleoceanographic change worldwide
13.  13. Assessing plants diversity in time and space may help conservation approaches
14.  14. Atmospheric paleo-particles and global environmental impacts
15.  15. Climate and environmental changes in permafrost regions: paleoecological perspectives
16.  16. Emerging physical and geochemical proxies in sedimentary paleoclimate studies
17.  17. Eolian Processes and Landscape Dynamics in Drylands
18.  18. Exploring Rapid Cultural Change: Tipping Points, Cascading Impacts and Human Societal Evolution.
19.  19. Historical Climate Reconstruction and Societal Impacts from Written Records

26.  26. Contribution of past fire time-series and models to fire science across the Earth system
27.  27. Reconstructing intermediate circulation and water mass properties through time
28.  28. Southeast Asian monsoon evolution during the Quaternary:records, synthesis and model results
29.  29. The Missing Piece: Holocene Records from Remote Areas
30.  30. Holocene coastal marine environments in the Arctic: proxy records and development
31. 31. Open Session on past global changes

Due to the very limited number (<4%) of abstract submission with online option for the conference, the Scientific Program Committee, after careful consideration, has decided to cancel the online participation option. So the 7th PAGES OSM will be held in person only rather than in the originally planned hybrid mode.
Please find the registration fees for online attendance here. Note that early bird rates also apply here.

Registration must be done online through the website. All users must create an account. Once registered with an account in the User Center, participants can register for the event, submit an abstract to a session, book accommodation, book the conference dinner and book field trips. Payment is also done through the User Center online either via credit card, or bank transfer.

The registration system is designed to ask you filling information about the way of payment for registration, but will not request payment before you proceed to abstract submission. Watch the detailed guideline file on how to register for the 7th PAGES OSM.

Click here for information on applying for financial support, or, go this page on the OSM website, find the article on "Financial support available to attend the OSM in Shanghai in 2025" and follow the instructions to download the form and submit it via email with required attachments.

Yes. Although both the Local Organizing Committee (LOC) and the PAGES IPO are aware that applicants will not know if they will receive financial assistance before the 1 December 10 December deadline, it is a requirement to register and submit an abstract, but please do so WITHOUT making any payment. Should the application for financial assistance not be successful, participants may delete their registration/ account in the User Center.

Each registered participant (either virtual or in-person) for the PAGES OSM meeting is allowed to submit a maximum of three abstracts. More information on Abstracts can be found here. 

After the deadline of 1 December 10 December, the abstracts will be reviewed by the convenors of the session. You will be informed within a month if your abstract has been accepted, rejected or referred to another session. 

All early bird registrations must be accompanied by payment. If payment is not provided, the registration will not be processed, and standard registration rates will apply. The deadline to register at the early bird rate is 1 Mar (23:59 CST, UTC/GMT+08).

Payment receipts for registration from the 7th OSM can be downloaded in the User Center after payment. Invoice in Chinese for the 7th OSM are not available yet.

The 7th OSM accepts credit card and wire transfer payments. You can make the payment through the User Center online. The last day to submit payment via wire transfer is 20 April 2025.

Written notifications must be emailed to the Conference Secretariat. Cancellations made before 1 March 2025 will be fully refunded. Participants cancelling before 20 April 2025 will receive a 50% refund. No cancellation allowance is possible from 21 April 2025 onwards.

Substitutions are allowed at any time but must be requested in writing by the original registrant and emailed to the PAGES 2025 Local Contact via pages2025@tongji.edu.cn. Partial substitutions are not allowed. Registrants must transfer their full registration to a new person.

Attendees will have the opportunity to adjust their registration type from virtual to in-person before the payment. Please click “Withdraw registration” in the User Center and register again to adjust your registration type.
If you've already paid the fee, we cannot adjust the registration type in the backend system. A Written notification must be emailed to the PAGES 2025 Local Contact via pages2025@tongji.edu.cn, and we will refund your registration fee and you can register for a new account.

*Please note we will not convert an in-person presentation to an online one on a temporary basis as this might cause issues.
