Joining Météo France means joining a multi-site organization, located in France, overseas, etc. Météo-France is organized into central and inter-regional divisions. Below is a presentation of the department you could join:
The Centre National de Recherches Météorologiques (CNRM) is the research department of Météo- France, Toulouse, France, jointy operated by Météo-France and CNRS (https://www.umr-cnrm.fr/).. Within CNRM, the climate research group is in charge of the development of global state-of-the-art CNRM Earth system model (CNRM-ESM), which includes components dealing with the atmosphere dynamics and chemistry (ARPEGE), ocean and sea ice (NEMO- GELATO), land surface & biosphere (SURFEX), and oceanic biogeochemistry processes (PISCES). CNRM has a long history within the climate research community and has contributed to the successive CMIP phases and IPCC reports. For IPCC Assessment Cycle 7, CNRM hosts two CLAs (WG1 Chap 9 and 2) and two LAs (WG1 Chap 5 and SR Cities Chap 2)).
Ai4PEX (01/04/2024 – 31/03/2027) is a multidisciplinary project composed by 18 European partners that aims to improve the representation of these feedbacks in ESMs, reducing uncertainty in global warming projections. We propose a multidisciplinary approach, focused on “learning” how to accurately describe processes underpinning these feedbacks, through a fusion of observations with advanced machine learning and artificial intelligence. Such data and approaches, constrained by the laws of physics, will deliver a step change in the accuracy of Earth system models.
Why join us?
Embark on a stimulating adventure in the service of all, alongside men and women committed to the daily challenges posed to our society by the weather and climate. And enjoy the following benefits: flexible working hours, RTT, telecommuting, administrative restaurant or luncheon voucher, 75% contribution to public transport, contribution to health insurance, sports and cultural associations depending on the site (climbing, gym, pottery, theater, etc.).
Other benefits await you, come and discover them!
Missions
The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change. It provides authoritative assessments in the form of reports involving the global scientific community.
Chapter Scientists (CS) play essential roles in the IPCC report drafting process. The CS role is usually undertaken by an early career scientist who supports a specific chapter, assisting on more technical tasks such as document and citation management and figure development. The CS role is a unique opportunity for early career scientists to gain experience and knowledge of the IPCC process and of the latest climate change research.
Here, we are seeking for a Chapter Scientist based at CNRM (Météo-France/CNRS), Toulouse, France for supporting the authors’ team of the Chapter 9 of the IPCC WGI. This chapter focuses on Earth system responses under pathways towards temperature stabilization, including overshoot pathways.
This position is opened for 12 months initially, and can be extended by two additional years. The position is based in Toulouse at CNRM, the National Centre for Meteorological Research, a joint research unit of Météo-France and CNRS.
The Chapter Scientist will work under direct supervision of Roland Séférian at CNRM, one the CLAs of IPCC Chapter 9, as well as the two other Coordinating Lead Authors (CLAs) Kaoru Tachiiri (SETAN, Japan) and Kirsten Zickfeld (Simon Fraser University, Canada).
Key Responsibilities
Scientific & Analytical Support
o Assist authors in compiling and analyzing large, multi-source datasets relevant to the chapter.
o Develop and share reproducible analysis scripts (e.g., Python, R) for figures, tables, and metrics used in the chapter.
o Ensure all data processing follows transparent and traceable workflows (Github, Gitlab)
o Assist authors in gathering, organizing, and referencing scientific literature.
o Help with drafting and formatting figures, tables, and boxes.
o Verify consistency of data, citations, and cross-references within the chapter.
Coordination & Logistics
o Organize and facilitate author meetings and virtual calls.
o Track deadlines, submissions, and revisions for the chapter.
o Maintain up-to-date records of chapter drafts and supplementary material.
Review Management
Coordinate the handling of expert and government review comments.
Ensure traceability of responses to all review comments.
Cross-Chapter Communication
Serve as a link between the chapter team, other chapters, and the Technical Support Unit (TSU).
Help maintain consistency across the report (terminology, style, figures).
Profile
Background in climate science or a related field (Master’s or PhD level preferred).
Ability to work in a multicultural, multidisciplinary and international environment, showing respect and flexibility.
Excellent organizational and communication skills (proficiency in written and spoken English).
Ability to synthesize complex information and pay attention to details.
Work flexibility given the work of the chapter that will take place across different time zones.
Familiarity with scientific publishing and large collaborative projects.
The application must include:
· A Curriculum vitae (including research experience, publications and conferences, computing skills and different language practice…);
· A brief statement of research interests;
· Names and contact details (email + telephone number) of three academic referees.
For any further information, please feel free to contact Mr Roland SEFERIAN (roland.seferian@meteo.fr) or Mrs Orane LEVERT (orane.levert@meteo.fr).
Application deadline : 16/10/2025
