IPCC: Call for authors and review editors for all Working Groups of the 7th Assessment Report (AR7)
The IPCC is looking for Coordinating Lead Authors, Lead authors, and Review Editors for the Seventh Assessment Report (AR7) of the IPCC. The deadline for nomination is 12 April 2025.

Deadline
For timely nomination, experts should fill in the nomination form of the corresponding Working Group until 12 April 2025 the latest (find below).
At its recent session the IPCC Panel agreed to continue to prepare comprehensive assessment reports and to maintain the existing Working Group structure under which:
- Working Group I assesses the scientific aspects of the climate system and climate change;
- Working Group II assesses the scientific, technical, environmental, economic, and social aspects of vulnerability to climate change, the negative and positive consequences of climate change, and options for adapting to it;
- Working Group III assesses the scientific, technical, environmental, economic, and social aspects of the mitigation of climate change.
Outline and schedule
The outline of the three Working Group reports is available here.
Expertise in demand
The IPCC requires that the nominee(s) have appropriate expertise. All nominations should indicate the chapter(s) and author role(s) for which the candidate is being nominated, a specification of the nominees’ key area of expertise and be accompanied by a curriculum vitae and a list of relevant publications.
Writing and review process
A detailed description of the IPCC writing and review process is contained in the “Procedures for the Preparation, Review, Acceptance, Adoption, Approval and Publication of IPCC Reports”.
The tasks and responsibilities for Coordinating Lead Authors, Lead Authors, and Review Editors are specified in the Annex 1 to these procedures.
Tasks
The task of Coordinating Lead Authors and Lead Authors is a demanding one. They are responsible for drafting the chapters and thereafter revising them considering comments submitted during the two IPCC-mandated reviews – namely an Expert Review and a second review by Governments and Experts.
Meetings
The Coordinating Lead Authors and Lead Authors will be expected to attend four Lead Author Meetings between 2025 and 2027/2028, and virtual chapter drafting meetings. A subgroup of authors will also contribute to drafting, revising, and finalizing the Summary for Policymakers (SPM) for each of the Working Group contributions to the AR7. The presence of Coordinating Lead Authors and select Lead Authors may be requested at Sessions of the IPCC and its Working Groups to assist in finalizing the SPMs.
The time commitment of Review Editors is less than that of Lead Authors but will include attendance at two Lead Authors Meetings during the latter half of the cycle.
Financial Support
ProClim on behalf of the FOEN will be able to reimburse travel (economy class) and accommodation costs to Coordinating Lead Authors, Lead Authors and Review Editors based in Switzerland. Unfortunately, a compensation for working time is not possible.
Selection
The IPCC requires that the nominee(s) have appropriate expertise. Coordinating Lead Authors, Lead Authors and Review Editors will be selected by the Working Group I, II and III Bureau. The composition of the group of Coordinating Lead Authors and Lead Authors for each chapter shall aim to reflect: the range of technical and socio-economic views and expertise, including experts from academia and practitioners and policymakers; geographical representation, ensuring appropriate representation of experts from developing and developed countries and countries with economies in transition; a mixture of experts with and without previous experience in IPCC; and gender balance.
