On behalf of the organizing committee and all Chinese paleolimnologists, we are pleased to announce that the 13th International Paleolimnology Symposium (IPS2015) will be held from August 4th - 7th 2015in Lanzhou, China. Please mark these dates in your calendars now and pass on the information to your colleagues and students. We hope to launch the conference's official website in April this year with additional details. The guiding theme of the IPS2015 is “Paleolimnological Perspectives on Environmental Change”, however we will also embrace all other aspects related to paleolimnological research. We aim to create an encouraging scientific environment for all paleolimnologists, and provide the opportunity to learn about the most recent advances, share ideas, synthesize new knowledge and facilitate collaboration in the paleolimnology community. We are planning to have about 20 sessions/keynotes and up to 500 presentations (with 130 talks plus posters). We invite paleolimnologists to propose sessions on a topic that matches your research field. The topics can be methodological, regional, thematic, review or issues-based. The sessions will commence with a 30 minute keynote talk followed by 15 minute conference presentations. Your session topic proposal should comprise a title, a short abstract, conveners' name(s), and may also include suggestions for keynote speakers. The IPS2015 committee will select sessions to ensure they cover a diverse range of topics and some proposals may be merged with others if there are not enough scientists to attend the session. Could you please submit your proposal by email to fhchen-IPS2015@lzu.edu.cn by 15 June 2014. We really appreciate your support and contributions
