From 7 to 10 April 2025, climate scientists, Earth system modellers, impact researchers, and science communicators will gather in Paris for a week dedicated to advancing our understanding of climate tipping points. The programme includes the TipESM & ClimTip Joint Conference, the TipESM Annual Meeting, and a dedicated Joint Project Meeting.

7–8 April 2025 | ClimTip & TipESM Joint Conference

On April 7 and 8, the TipESM & ClimTip Joint Conference will take place at the Henri Poincaré Institute at Sorbonne University. Organised by the two Horizon Europe projects, the event will bring together experts working at the forefront of tipping point research and serve as a platform for clustering Horizon Europe initiatives.

Throughout the two-day event, the conference will:

• Share knowledge across the clustered projects to strengthen impact and research in tipping point initiatives
• Present the latest progress and findings across five critical themes: Cryosphere, Biosphere, AMOC & SPG, Tipping point prediction methodologies, and Impacts and communication
• Empower and initiate interdisciplinary collaboration, connecting researchers across different expertise and projects
• Improve communication by translating complex science into impactful insights for the public, media, and policymakers

9–10 April 2025 | ClimTip Annual Meeting

From April 9 to 10, ClimTip will hold its Annual General Assembly Meeting. This internal meeting will explore the progress made across the project’s six scientific themes and set the course for upcoming research from the corresponding project Work Streams (WS) and Work Packages (WP).

The six themes are:

1. Better Understand Tipping Points and Improve Climate Models
   1. Reporting activities in WS1 (WP1-4)
2. Model Climate and Ecosystem Tipping Elements
   1. Reporting activities in WS2, ice sheets and paleo (WP5-6)
   2. Reporting activities in WS2, AMOC and ARF (WP7-9)
   3. ESM simulations and data management
3. Investigate Impacts of Tipping Points
   1. Reporting activities in WS3 (WP10-12)
4. Address Mitigation, Adaptation and Socioeconomic Costs
   1. Reporting activities in WS4 (WP13-16)
5. Assessing the impacts of tipping points on ecosystems and society
   1. Reporting activities in WS5 (WP17-18)

9–10 April 2025 | TipESM Annual Meeting

In parallel, TipESM will also hold its Annual Project Meeting focusing on the progress made across the project’s six scientific themes and set the course for upcoming research from the project.

The six themes are:

1. Simulating tipping points in the Earth system with an ensemble of ESMs and dedicated experiments
2. Delivering new knowledge on climate tipping points and their driving processes
3. Developing early warning indicators and assessing the risk for cascades of tipping points across the Earth system
4. Identifying climate-driven tipping points in ecosystems and society
5. Assessing the impacts of tipping points on ecosystems and society
6. Constraining future tipping point risks and providing safe mitigation emission pathways

10 April 2025 (Afternoon) | ClimTip & TipESM Joint Project Meeting

On the afternoon of April 10, the ClimTip & TipESM teams will reconvene for a Joint Project Meeting to build on the outcomes of the Joint Conference earlier in the week. The joint meeting will sum up the insights and discussions from the conference themes and take these insights further through breakout groups. As a common thread throughout both projects, the joint project meeting will include a dedicated session on storylines, focusing on how to integrate scientific findings into compelling, policy-relevant narratives that can connect science, risk, and communication.
